SummaryOverview
The
reverse total shoulder replacement arthroplasty enables experienced shoulder
surgeons to treat patients with conditions that previously had no solution.
These conditions include rotator cuff tear arthroplasty, instability with
anterosuperior escape, pseudoparalysis, and failures of surgery for arthritis
and facture management.
Rotator
cuff tear arthropathy (arthritis with a large cuff defect) is a devastating
condition that seriously compromises the comfort and function of the shoulder.
This condition is characterized by the irreparable loss of the rotator cuff
tendons and destruction of the normal joint surface of the shoulder. Because
these tissues cannot be restored, the shoulder is often weak, painful, and
unstable. Using special techniques and a reversed total shoulder design [Figure 1] qualified surgeons can improve the
stability of the shoulder and enable the deltoid muscle to power it, even in
the absence of a normal rotator cuff.
By
contrast, when the rotator cuff is intact, shoulder arthritis is often best
treated by a convential total shoulder replacement. In certain milder cases of rotator cuff tear
arthropathy of the shoulder without instability, a special prosthesis with a CTA head may be indicated.
Failed
conventional shoulder joint replacements and failed fracture surgery may also
be treatable using a reverse total shoulder replacement.

In
the normal shoulder, the rotator cuff muscles, including the supraspinatus,
help balance the ball of the arm bone (humeral head) in the socket against the
upward pull of the deltoid muscle. [Figure 2].
In
rotator cuff tear arthropathy, the rotator cuff tendons that normally are
interposed between the humeral head and the overlying coracoacromial arch
become progressively thinned until the humeral head moves upwards and rubs
against the bone of the arch. [Figure 3].
In
stage 1A of rotator cuff tear arthropathy the humeral head remains centered in
the socket (glenoid) in spite of a large rotator cuff tear [Figure 4]. In stage
1B of rotator cuff tear arthropathy the humeral head migrates medially into the
socket (glenoid) [Figure 5]. In stage 2A of rotator cuff tear arthropathy the
humeral head migrates upwards, but is stabilized by the overlying
coracoacromial arch in spite of the lack of rotator cuff. [Figures 6 and 7]. In
stage 2B of rotator cuff tear arthropathy the humeral head is unstable,
migrating upwards and forwards because it is no longer held in position by the
coracoacromial arch. This condition often arises after previous procedures such
as an acromioplasty when performed in the presence of a large cuff tear.
[Figure 8] In this situation, the arm often cannot be raised from the side,
even though the deltoid muscle is working; this is called ‘pseudoparalysis’.
After
performing a clinical exam, a shoulder surgeon experienced with rotator cuff
tear arthropathy can suggest what type of surgery is most likely to be helpful to
the individual with the condition. Individuals are most likely to benefit from
this surgery if they are well motivated and in good health.
Shoulders
demonstrating changes of Stages 1A, 1B, and 2A with substantial loss of comfort
and function may be considered for shoulder arthroplasty using a cuff tear arthropathy
(CTA) prosthesis.
Shoulders
with stage 2B cuff tear arthropathy and with substantial loss of comfort and
function are considered for the reversed total shoulder (reverse Delta)
prosthesis because other options may not provide sufficient stability for the
humeral head (ball of the shoulder joint). The reversed (reverse Delta) total
shoulder prosthesis is designed with a socket where the ball (head of the
humerus) is normally located and a ball where the socket (glenoid) is usually
located. This configuration adds stability so that the deltoid muscle can power
the shoulder.
The
goal of reverse total shoulder replacement is to restore some function to the
joint destroyed as a result of cuff tear arthropathy by providing stability and
a fulcrum against which the deltoid muscle can help elevate the shoulder to a level
where some basic shoulder functions can be performed.
Reverse
total shoulder replacement is a highly technical procedure and is best
performed by a surgical team who has experience with this surgery. Such a team
can maximize the benefit and minimize the risks of surgery.
The
two-hour reverse total shoulder replacement is performed under general (or
nerve block) anesthesia.
Use
of the arm is started several weeks after the procedure. Extensive therapy is
not needed with reverse shoulder surgery.
This procedure does not restore the ability of
the shoulder to perform heavy work or sport.
Characteristics of reverse shoulder replacement Rotator cuff tear arthropathy (or shoulder arthritis with a large
rotator cuff tear) is a severe and complex form of shoulder arthritis
in which the shoulder has lost not only the cartilage that normally
covers its joint surface, but also the tendons of the rotator cuff tear
which help position and power the joint. [Figure 9]
Normally, the tendons of the rotator cuff (large arrows) allow
smooth motion of the upper end of the arm bone (humerus) beneath the
overlying bones, ligaments, tendons and muscles. [Figure 10]
When the rotator cuff is degenerated, chronically torn or otherwise
deficient, the normally smooth upper surface of the upper end of the
arm bone (humeral head) is unprotected from rubbing with the
undersurface of the bone and ligaments above as shown by the large
arrow. [Figure 11]
In cuff tear arthropathy, the upper surface of the ball of the upper
arm bone (humeral head) becomes roughened as it rubs against the
overlying bone (the acromion) as shown by the arrow. [Figure 12] This
condition results in shoulder pain, weakness, stiffness and grinding on
movement. Types Rotator cuff tear arthropathy appears to be a condition with a
succession of stages, depending on the stability of the humeral head
(ball of the shoulder joint) in respect to the glenoid (socket of the
shoulder joint). These stages have been described at the beginning of this article.Similar conditions Shoulder arthritis with a massive cuff defect must be distinguished
from arthritis without substantial rotator cuff involvement, from
isolated rotator cuff disease, from frozen shoulder, and from neck
arthritis, each of which may produce somewhat similar symptoms.
Arthritis usually gives rise to stiffness without weakness. Rotator
cuff tears usually cause pain and weakness, but stiffness is less
common. Frozen shoulder is characterized by shoulder stiffness, but the
X-rays are usually normal. Neck arthritis may cause shoulder pain and
weakness that is worse when the head is held in certain positions.Incidence and risk factors Rotator cuff tear arthropathy (or shoulder arthritis with a large
rotator cuff tear) most commonly occurs in individuals over the age of
65 and is more common in women than men.
Diagnosis Rotator cuff tear arthropathy (or shoulder arthritis with a large
rotator cuff tear) is diagnosed by a history of progressive loss of
shoulder function, usually without an injury, along with a physical
examination showing weakness and grinding on movement and a typical
appearance on X-ray. In these films the humeral head can be seen
contacting the undersurface of the coracoacromial arch (indicated by
the arrows). [Figure 13] The most important test for cuff tear
arthropathy is the x-ray, characteristically showing rounding off of
the humeral head as it contacts with the undersurface of the
coracoacromial arch.
[Figure 14]
Rotator cuff tear arthropathy (arthritis of the shoulder associated
with a massive cuff tear) is best diagnosed by an orthopaedic surgeon
with experience in shoulder disorders. Certain surgeons specialize in
rotator cuff tear arthropathy (arthritis of the shoulder associated
with a massive cuff tear). Such individuals may be found in the
shoulder services of major schools of medicine. Medications Mild analgesic medications may relieve some of the symptoms of cuff tear arthropathy.Exercises If the symptoms of rotator cuff tear arthropathy (shoulder arthritis
with a massive rotator cuff tear) are mild, the condition may be
treated with gentle motion exercises and exercises to strengthen the deltoid and other muscles around the shoulder that remain intact. Possible benefits of reverse shoulder replacement When exercises are not successful, most cases of cuff tear arthropathy are considered possible candidates for shoulder joint replacement arthroplasty with a cuff tear arthropathy
(CTA) head prosthesis that allows arthritic shoulders to regain some of
their lost comfort and function. However, when the shoulder is no
longer stabilized with the ball in the socket, consideration can be
given to a reversed (reverse Delta) prosthesis.
Joint replacement surgery can improve the mechanics of the shoulder,
but cannot make the joint as good as it was before the onset of rotator
cuff tear arthropathy. The effectiveness of the procedure depends on
the health and motivation of the individual, the condition of the
shoulder, and the expertise of the surgeon. When performed by an
experienced surgeon, shoulder replacement arthroplasty with reversed
(reverse Delta) prosthesis can provide improved stability along with
improved shoulder comfort and function. The greatest improvements are
in the ability of the individual to sleep and to perform some of the
simple activities of daily living. In that the tendons of the rotator
cuff are not repairable in this condition, normal strength and function
of the shoulder cannot be regained. Types of surgery recommended Three types of surgery can be helpful in the management of rotator
cuff tear arthropathy (shoulder arthritis associated with massive
rotator cuff defects). The surgical procedures can range from a simple
smoothing of the roughened bone [Figure 15] to a resurfacing of the
humeral head with a smooth prosthesis, such as one with a rotator cuff tear arthropathy
(CTA) head fixed to the shaft of the arm bone (humerus) [Figure 16]. If
the joint is unstable, a reversed prosthesis, such as the reverse Delta
[Figure 17] may be needed.
Who should consider reverse shoulder replacement ? Individuals with rotator cuff tear arthropathy complicated by
shoulder instability should consider joint replacement surgery with a
reversed (reverse Delta) prosthesis if
- the cuff tear arthropathy complicated by instability is a major problem for the individual,
- the individual is sufficiently healthy to undergo the procedure,
- the individual understands and accepts the risks and alternatives,
- there is sufficient bone to permit the surgery,
- the surgeon is experienced in shoulder replacement surgery with a reversed (reverse Delta) prosthesis, and
- no other surgical options are preferable for the individual's shoulder
Shoulder replacement surgery with a reversed (reverse Delta)
prosthesis is most effective when the individual follows a simple
exercise program after surgery and understand the limitations of the
procedure. Thus, the individual ? motivation and cooperation are
important elements of the partnership. What happens without surgery? The rate of progression of rotator cuff tear arthropathy (shoulder
arthritis with a massive rotator cuff defect) is usually slow, thus
surgery is not urgent. Serious instability with associated loss of
function can motivate prompt surgical consideration, however.
Surgical options Three types of surgery can be helpful in the management of rotator cuff
tear arthropathy (shoulder arthritis associated with massive rotator
cuff defects). The surgical procedures can range from a simple
smoothing of the roughened bone to a resurfacing of the humeral head
with a smooth prosthesis, such as a cuff tear arthropathy
(CTA) head, fixed to the shaft of the arm bone (humerus). If the joint
is unstable, a reversed prosthesis, such as the reverse Delta may be
needed.Effectiveness In the hands of an experienced surgeon, shoulder arthroplasty with a
reversed (reverse Delta) prosthesis can be helpful in restoring
stability, comfort and function to the shoulder of a well-motivated
individual with cuff tear arthropathy complicated by instability. The
greatest benefits are often the ability to sleep on the affected
shoulder and the ability to perform simple activities of daily living.
As long as the shoulder is cared for properly and subsequent injuries
are avoided, the benefit can last for years.
Urgency In that rotator cuff tear arthropathy progresses slowly, consideration
of surgery is not urgent. Before surgery is undertaken, the individual
needs to be in optimal health, understand and accept the risks and
alternatives of surgery, and understand the postoperative
rehabilitation program. Only if there is concern about the possibility
of infection in a swollen, warm and red shoulder does urgent surgery
demand consideration. If there is an infection, prosthesis would not be
inserted, but rather the shoulder would require surgical cleaning out
and extensive postoperative antibiotics.Risks Shoulder replacement surgery for rotator cuff tear arthropathy using a
reversed (reverse Delta) prosthesis carries significant risks that are
important for the individual to consider. The risks of this surgery
include but are not limited to the following: infection (which can be
sufficiently serious to require revision surgery, including removal of
the prosthesis), injury to nerves and blood vessels, fracture,
stiffness or instability of the joint, dislocation, loosening of the
prosthesis, pain, failure of tendon or muscle attachment, and the need
for additional surgeries ? any or all of which may result in major loss
of function to the arm. There are also risks of anesthesia and blood
transfusion (although transfusions are not usually necessary). An
experienced shoulder joint replacement team will use special techniques
to minimize these risks, but cannot totally eliminate them.Managing risk Some of the risks of shoulder replacement surgery with a reversed
(reverse Delta) prosthesis can be effectively managed if they are
promptly identified and treated. Infections may require a wash out in
the operating room?sometimes complete removal of the prosthesis is
necessary. Blood vessel or nerve injury may require repair. Fracture
may require surgical fixation. Stiffness or instability may require
exercises or additional surgery. Loosening of the prosthesis may
require surgical revision. If the individual has questions or concerns
about the course after surgery, the surgeon should be informed as soon
as possible.
Preparation Shoulder joint replacement surgery with a reversed (reverse Delta)
prosthesis is considered for healthy and motivated individuals in whom
cuff tear arthropathy is complicated by instability that interferes
with the comfort and function of the shoulder.
Successful shoulder replacement depends on a partnership between the
individual and the experienced shoulder surgeon. Individuals should
optimize their health so that they will be in the best possible
condition for this procedure. Smoking should be stopped a month before
surgery and not resumed for at least three months afterwards. Any
heart, lung, kidney, bladder, tooth, or gum problems should be managed
before surgery. Any infection may be a reason to delay the operation.
The shoulder surgeon needs to be aware of all health issues, including
allergies and the non-prescription and prescription medications being
taken. Some of these may need to be modified or stopped. For instance,
aspirin and anti-inflammatory medication may affect the way the blood
clots.
The incision used for a shoulder replacement with a reversed
(reverse Delta) shoulder is usually made across the side of the
shoulder. [Figure 18] Occasionally it is made in the front of the
shoulder. The area of the skin incision must be clean and free from
sores and scratches.
Before surgery, the individual should consider the limitations,
alternatives and risks of surgery. Individuals should also recognize
that shoulder replacement with a reversed (reverse Delta) prosthesis
cannot restore normal function to the severely damaged shoulder.
The individual needs to plan on carefully protecting the arm for
three to six weeks after the procedure. Driving, shopping and
performing usual work or chores may be difficult after surgery. Plans
for necessary assistance need to be made before surgery. For
individuals who live alone or those without readily available help,
arrangements for home help should be made well in advance.
Timing Shoulder replacement arthroplasty can be delayed until the time that is
best for the individual's overall health and convenience. However,
excessive delays can result in the loss of bone making the
reconstruction more difficult for the surgeon and the individual.Costs The surgeon's office should provide a reasonable estimate of the
surgeon's fee and the hospital fee.Surgical team Shoulder replacement arthroplasty with a reversed (reverse Delta)
prosthesis for cuff tear arthropathy complicated by instability is a
technically demanding procedure that should be performed by an
experienced surgeon in a medical center experienced in performing
similar shoulder joint replacements. Individuals should inquire as to
the number of shoulder arthroplasty procedures that the surgeon
performs each year and the number of these procedures performed in the
medical center each year.Finding an experienced surgeon Because relatively few shoulder arthroplasties are performed in the
United States each year, it is unlikely that every community has an
experienced shoulder arthroplasty surgeon who frequently performs
arthroplasties for cuff tear arthropathy . Surgeons specializing in
shoulder joint replacement may be located through university schools of
medicine, county medical societies, or state orthopaedic societies.
Other resources include local rheumatologists or professional societies
such as the American Shoulder and Elbow Surgeons society.Facilities Shoulder replacement arthroplasty is usually performed in a major
medical center that performs these procedures on a regular basis. These
centers have surgical teams and facilities specially designed for this
type of surgery. They also have nurses and therapists who are
accustomed to assisting individuals in their recovery from shoulder
replacement surgery.
Technical details Shoulder replacement surgery with a reversed (reverse Delta)
prosthesis for cuff tear arthropathy complicated by instability is a
highly technical procedure; each step plays a critical role in the
outcome.
After the anesthetic has been administered and the shoulder is
prepared, an incision is usually made across the side of the shoulder
from above the collarbone to the middle of the arm bone as shown in the
figure. [Figure 19] The deltoid is split along the direction of its
fibers taking care to avoid the axillary nerve that runs on its
inferior surface. Opening the shoulder reveals the irregular joint
surface of the humeral head. [Figure 20] This surface is resected using
a cutting guide. [Figure 21 and 22] Instead of duplicating the normal
30-degree posterior direction of the humeral head joint surface the
head is cut so that it faces directly medially.[Figure 23 and 24]. The
shaft of the arm bone (humerus) is prepared to receive the stem of the
humeral component. [Figures 25, 26 and 27]. Additional reamers are used
to prepare the neck of the humerus [Figures 28. 29, and 30]. The
definitive humeral prosthesis body [Figure 31] is inserted into the
prepared bone [Figure 32].
Attention is then directed to the glenoid, which is surgically
exposed [Figure 33] and a pin driven into its center to act as a guide
[Figure 34]. The glenoid surface is then drilled [Figure 35] and reamed
to a flat surface [Figure 36]. The base of the socket (metaglene) is
then inserted onto the prepared surface and fixed into position using
four screws. [Figure 37]. The inferior and superior screws lock into
the metaglene, while the anterior and posterior screws are not locking.
[Figure 38]
A trial ball (glenosphere) is placed on the metaglene and a trial
cup is placed on the humeral component allowing the surgeon to examine
the shoulder for stability. [Figure 39 and 40]. If the soft tissue
tension is insufficient for stability, an extended neck can be added to
the humeral prosthesis [Figure 41 and 42].
Once the optimal trial components and the positions of the humeral
and glenoid components verified, the definitive glenosphere is screwed
onto the metaglene [Figure 43]. The definitive humeral socket is then
fixed to the humeral prosthesis. [Figure 44]
At the conclusion of this procedure, the subscapularis tendon is securely repaired to the bone.
X-rays are taken to document the position and orientation of the prosthesis.

Anesthetic Shoulder joint replacement surgery may be performed under a general
anesthetic or under a brachial plexus nerve block. The individual
should discuss his or her preferences with the anesthesiologist before
surgery.Length of reverse shoulder replacement The procedure usually takes approximately two hours, however the
preoperative preparation and the postoperative recovery may add several
hours to this time. Individuals often spend two hours in the recovery
room and two to four days in the hospital after surgery.
Pain and pain management Recovery of comfort and function after humeral prosthetic
arthroplasty with a cuff tear arthropathy head is progressive after the
surgery. Often the benefits become apparent to the individual after two
to six weeks.
This partial joint replacement procedure is a major surgical
procedure that involves cutting of skin, tendon and bone and removal of
scar tissue, as well as resuturing of tendon back to bone. The pain
from this surgery is managed by the anesthetic and by pain medications.
Immediately after surgery, strong medications (such as morphine or
Demerol) may be given by injection and by mouth as needed. Within a day
or so, oral pain medications (such as hydrocodone or Tylenol with
codeine) are usually sufficient. On the other hand, some individuals
need surprisingly little pain medication after this procedure. In older
individuals it is often safer to use relatively less pain medication. Use of medications Initially after surgery pain medication can administered by mouth,
in the vein (intravenously), or in the muscle (intramuscularly).
Sometimes patient controlled analgesia (PCA) is used to allow the
individual to administer the medication as it is needed. Hydrocodone or
Tylenol with codeine are taken by mouth. Intravenous pain medications
are usually needed only for the first day or two after the procedure.
Oral pain medications are usually needed only for the first two weeks
after the procedure. Some individuals need surprisingly little pain
medication after this procedure. In older individuals it is often safer
to use relatively less pain medication.
Effectiveness of medications Pain medications can be very powerful and effective. Their proper
use lies in the balancing of their pain relieving effect and their
other, less desirable effects (such as slowed breathing, sleepiness,
nausea, constipation, or difficulty urinating). Good pain control is an
important part of the postoperative management.
Important side effects Pain medications can cause drowsiness, slowness of breathing,
difficulties in emptying the bladder and bowel, nausea, vomiting and
allergic reactions. Individuals who have taken substantial narcotic
medications in the recent past may find that usual doses of pain
medication are less effective. For some individuals, balancing the
benefit and the side effects of pain medication is challenging.
Individuals should notify their surgeon if they have had previous
difficulties with pain medication or pain control.Hospital stay After surgery the individual spends an hour or so in the recovery
room. A drainage tube is usually used to remove excess fluid from the
surgical area. The drain is usually removed on the second day after
surgery. Bandages cover the incision. They are usually changed the
second day after surgery.
Individuals are discharged as soon as the incision is dry, the shoulder
is comfortable with oral pain medications, the individual can care for
the shoulder, and the home support systems for the individual are in
place. Discharge is usually on the third or fourth day after surgery.
Recovery and rehabilitation in the hospital Early protected and restricted motion after shoulder replacement
with a reversed (reverse Delta) prosthesis helps achieve the best
possible shoulder function. The surgeon will provided detailed
information on the optimal program after the particular surgical
procedure.
During the hospitalization, the individual learns a simple
rehabilitation program that will be used at home after discharge. The
arm is kept in a sling for several weeks after surgery to allow for
early healing. Hospital discharge At the time of discharge, the individual should be relatively
comfortable on oral medications, should have a dry incision, should
understand their exercises and should feel comfortable with the plans
for managing the shoulder. For the first month or so after this
procedure, the operated arm may be less useful than it was immediately
beforehand.
The specific limitations can be specified only by the surgeon who
performed the procedure. It is important that the reconstructed
shoulder not be challenged until it has had a chance to heal. Usually
the individual is asked to lift nothing heavier than a cup of coffee
for six weeks after the surgery.
Management of these limitations requires advance planning to
accomplish the activities of daily living during the period of recovery. Convalescent assistance Individuals usually require some assistance with self-care,
activities of daily living, shopping and driving for at least six weeks
after surgery. They usually go directly home after this surgery,
especially if there are people at home who can provide the necessary
assistance, or if such assistance can be arranged through an agency. In
the absence of home support, a convalescent facility may provide a safe
environment for recovery.
Recovery of comfort and function after shoulder arthroplasty
continues for many months after the procedure. Improvement in some
activities may be evident as early as six weeks. With persistent
effort, individuals can make progress for as long as a year after
surgery.
Physical therapy Limited use after total shoulder replacement with a reversed
(reverse Delta) prosthesis is critical for protection during the early
phases of healing.
Most individuals find the recovery of comfort and function can be
accomplished without formal physical therapy.
Rehabilitation options It is often most effective for the individual to carry out her or
his own rehabilitation at home. Often no physical therapy is
recommended.
Can rehabilitation be done at home? In general the rehabilitation is best performed by the individual at
home. Occasional visits to the surgeon or therapist may be useful to
check the progress and to review the program.Usual response Individuals are almost always satisfied with the increases in
comfort and function that are achieved with the rehabilitation program.
If the exercises are uncomfortable, difficult, or painful, the
individual should contact the surgeon promptly.
Risks The rehabilitation program is safe with little risk.Duration of rehabilitation Once the rehabilitation goals are achieved, the exercise program can be cut back to a minimal level.Returning to ordinary daily activities In general, individuals are able to perform gentle activities of
daily living with the operated arm at the side starting four weeks
after surgery. Walking with the arm protected is strongly encouraged.
Driving should wait until the individual can perform the necessary
functions comfortably and confidently. This may take up to six weeks if
the surgery has been performed on the right shoulder, because of the
increased demands on the right shoulder for shifting gears.
With the consent of their surgeon, individuals may be able to return
to certain activities at six months after surgery. It is important to
remember that shoulder arthroplasty with a reversed (reverse Delta)
prosthesis does not restore the function of the degenerated rotator
cuff tendons so that the shoulder will never totally regain full
comfort, strength, range of motion or function. Stressful activities
and activities with the arm in extreme positions may never be possible
after this procedure. Long-term patient limitations Individuals should avoid activities that involve major impact
(chopping wood, contact sports, activities with major risk of falls) or
heavy loads (lifting of heavy weights, heavy resistance exercises)
after this surgery. In this way the risk of re-injury is minimized.
Costs The surgeon and therapist should provide the information on the usual
cost of the rehabilitation program. The program is quite
cost-effective, because it is based heavily on home exercises.Summary of reverse shoulder replacement for reverse shoulder replacement Rotator cuff tear arthropathy (arthritis with a massive cuff defect)
with shoulder instability is a devastating condition that seriously
compromises the comfort and function of the shoulder. This condition is
characterized by the permanent loss of the rotator cuff tendons and the
normal surface of the shoulder joint. These tissues cannot be restored
to their normal condition and the lost comfort and function of the
shoulder cannot be totally regained.
However, in the hands of an experienced surgeon and in a
well-motivated individual, shoulder replacement surgery with a reversed
(reverse Delta) prosthesis along with careful post-surgical
rehabilitation can help restore substantial comfort and function to
shoulders damaged by cuff tear arthropathy and instability.
Pre-planning and persistent rehabilitation efforts will help assure
the best possible result for the individual with rotator cuff tear
arthropathy.
