Hemiarthroplasty shoulder is a surgical procedure that replaces a shoulder joint using a prosthesis. The procedure uses a rounded replacement socket that is placed on the humerus. It can help patients with rotator cuff arthropathy. However, it may not be the right choice for those with structural damage to the rotator cuff. Another contraindication is a fracture in the glenoid bone. In these cases, your healthcare provider may recommend an alternative procedure.
Resurfacing hemiarthroplasty is a form of shoulder joint replacement that can be an effective solution for restoring shoulder function and socket integrity. This type of surgery can be very beneficial for patients with a variety of conditions, including avascular necrosis, different types of arthritis, and rotator cuff injuries. Although it does not always restore full range of motion, it can greatly improve the patient’s pain and function.
In a meta-analysis of 112 studies, resurfacing hemiarthroplasty shoulder was associated with a lower complication rate than total shoulder arthroplasty. The primary indication for revision was component loosening, followed by rotator cuff failure, and infection. Overall, the intraoperative and postoperative complication rates were low. The highest rate of postoperative complications was iatrogenic humeral fractures (91/230, 40%), while the lowest rate was associated with infection (216/825, 26%).
Although total shoulder arthroplasty is the accepted procedure for treating patients with glenohumeral osteoarthritis, some surgeons prefer resurfacing hemiarthroplasty for younger patients. There is also controversy over the choice between stemmed hemiarthroplasty and SHA. A recent meta-analysis examined the results of both procedures for patients with glenohumeral arthritis. Functional outcomes such as range of motion and pain relief were measured postoperatively. Complication rates were also compared to the rate of revisions.
Patients with shoulder resurfacing procedures typically stay in the hospital for one to two days. Following the surgery, they may perform limited exercises and wear a sling for several weeks. After six weeks, they may resume driving and golfing. However, high-contact sports, such as soccer, are generally prohibited after shoulder resurfacing.
The patient’s primary care physician may order diagnostic tests to determine the cause of the problem. The doctor may also recommend preoperative strengthening of the surrounding muscles. Strengthening these muscles will help the patient recover better after surgery. After a shoulder surgery, the muscles tend to atrophy, so the strength of these muscles is critical.
Glenoid Fracture Compromising The Stability Of The Shoulder
Glenoid fracture is a complication after hemiarthroplasty and is associated with instability of the shoulder. It is caused by anterior HAGL lesions and results in failure of the surgical Bankart repair. This is one of the most common and complicated injuries that arise after hemiarthroplasty.
While labral resection has the potential to increase the risk of glenohumeral translation, this procedure also carries a risk of glenoid fracture, a potentially devastating complication. This fracture, in conjunction with labral resection, can compromise the stability of the shoulder.
A glenoid fracture associated with posteriorly directed force can cause anterior glenohumeral dislocation. This dislocation occurs when the humerus impinges on the anteroinferior glenoid rim. This fracture can also result in a subcoracoid fracture and labral injury.
Another complication is called the osseous Bankart lesion. The lesions may involve the anteroinferior right glenoid rim. In such a case, the osseous defect is calculated as the ratio of the osseous fragment’s surface area to a circle covering the inferior two thirds of the glenoid fossa. Other measurements that can help diagnose this complication are the abnormal glenoid width compared to the normal contralateral glenoid width.
Glenoid fractures are more common in the glenoid side of the shoulder than the humeral side. This is one of the reasons that patients may need a revision surgery to fix the glenoid component. This is a relatively common complication after hemiarthroplasty. Glenoid fractures are more difficult to repair than the humeral side and may require bone grafting.
In addition to identifying the cause of the fracture, doctors can also use the patient’s medical history to make an accurate diagnosis. The patient’s history may reveal any past shoulder complaints and whether there were concomitant injuries. Moreover, a patient’s postoperative course after hemiarthroplasty may also be helpful in determining a suitable course for revision surgery. For example, postoperative numbness or paresthesia could be indicative of a brachial plexus injury or other nerve injury. Additionally, wound healing problems may indicate an infection.
The glenoid fossa is responsible for providing a stable articular surface for the humeral head. It also prevents lateral translation. It is made up of a rim of fibrous tissue that bridges the glenoid with the joint capsule, a synovial membrane.
Recovery After A Hemiarthroplasty
A hemiarthroplasty shoulder surgery can result in a long recovery period for the shoulder. The recovery process can last anywhere from three to six months, depending on the patient’s condition and the type of surgery performed. Following surgery, patients will begin physical therapy and begin to slowly increase activity levels. They may need to wear a sling for several weeks and limit their activities.
One to two weeks before surgery, patients will have pre-operative tests performed. These may include an electrocardiogram to check the heart’s electrical activity and a blood test. Patients may be given an IV line to administer medications and fluids. Patients will also receive pain medication. They may stay in the hospital overnight or go home the day of surgery, depending on the doctor’s instructions.
Shoulder hemiarthroplasty is a surgical procedure that replaces the humeral head with a metal implant. The glenoid remains intact. Patients undergo this procedure if they suffer from severe shoulder osteoarthritis. A second type of hemiarthroplasty, called resurfacing hemiarthroplasty, involves replacing the humeral head’s joint surface with a cap-like prosthesis. This technique preserves the bone and avoids component wear.
Depending on the type of surgery performed, patients may need to modify their activity levels. They may not be able to engage in vigorous activities right away, but they may be able to play some sports. The recovery time depends on the extent of the immobilization and other factors. If the shoulder replacement surgery is successful, the patient should be able to return to normal activities.
Before RnR surgery, patients should develop a close relationship with their surgeon. This relationship provides structure and assurance for the patient. This relationship may also improve postoperative outcomes. The surgeon and his or her team will also be available to offer additional support and education. Patients will also receive instructions on exercises necessary to recover from the surgery.
Patients should avoid strenuous activities or extreme positions for six weeks after surgery. In addition, patients should avoid reaching for objects that are too heavy or too low. They should also avoid putting their arm behind their back for six weeks.
Comparison Of Hemiarthroplasty With Reversal Total Shoulder Replacement
The RTSA, or reversal total shoulder arthroplasty, is a newer type of arthroplasty, and rates are steadily increasing globally. However, RTSA implantations are also associated with higher rates of complications and revision surgeries. Consequently, there is an urgent need to evaluate salvage therapies, including hemiarthroplasty, for patients who undergo failed RTSAs.
This study compared the two procedures using preoperative factors as predictors of patient outcome. The main outcomes were decreased pain and limited range of motion after surgery, and a reduction in rotator cuff deficiency. Overall, patients who underwent hemiarthroplasty improved 19 degrees of shoulder elevation after surgery, and those who had a torn rotator cuff were better than those who underwent total shoulder replacement.
There were several limitations to this study. Firstly, the study was conducted at only one institution. In addition, the participants were orthopedic surgeons from two subspecialties, which may have influenced results. Another limitation was the small sample size. Longer follow-ups are needed to identify any additional complications, such as conversion from HA to RSA or failure of the reverse prosthesis.
The two approaches are very different in some aspects. Both surgeries involve a reduction in the size of the incisions. For example, hemiarthroplasty can remove bone fragments from the shoulder without removing the tissue from the joint. However, reversal total shoulder replacement involves removing the affected part of the joint.
This type of arthroplasty is used to repair fractures of the proximal humerus. In addition, it is commonly used for patients with poor bone quality or fracture patterns. Reverse total shoulder arthroplasty is less dependent on tuberosity healing and provides improved functional outcomes.
The prosthesis for a reversal total shoulder replacement is composed of 5 parts: the glenosphere, the polyethylene cup, the humeral neck, and the humeral stem. There have been no long term studies of this surgery in the United States. However, shoulder surgeons in Europe report that the prosthesis has a high survival rate, with an average of 15 years.
Complication rates are similar between the two techniques. Infection, nerve damage, and dislocation of the prosthesis are the major risks with both. Revision cases can take a longer time than first joint replacement. Recovery time for function of the arm can also be extended, depending on whether bone grafting is required.
