As reverse shoulder replacement has become more popular, the indications have expanded to include shoulder “pseudoparalysis” due to massive rotator cuff tears, shoulder fractures, severe bone loss on the scapula or humerus precluding the use of standard implants and failed prior shoulder replacement procedures. [6]
The development of safer, more effective techniques have led to the increased use of reverse total shoulder arthroplasty. [4] Reverse total shoulder arthroplasties are typically indicated when the rotator cuff muscles are severely damaged. [14] There are a few major approaches for reverse total shoulder arthroplasties. The first is the ...
A dislocated shoulder can be treated with: arthroscopic repairs; repair of the glenoid labrum (anterior or posterior) [1] In some cases, arthroscopic surgery is not enough to fix the injured shoulder. When the shoulder dislocates too many times and is worn down, the ball and socket are not lined up correctly.
In a small minority of cases where extensive arthritis has developed, an option is shoulder joint replacement (arthroplasty). Specifically, this is a reverse shoulder replacement, a more constrained form of shoulder arthroplasty that allows the shoulder to function well even in the presence of large full thickness rotator cuff tears.

Bone healing, or fracture healing, is a proliferative physiological process in which the body facilitates the repair of a bone fracture. Generally, bone fracture treatment consists of a doctor reducing (pushing) displaced bones back into place via relocation with or without anaesthetic, stabilizing their position to aid union, and then waiting ...
Shoulder arthritis is a clinical condition in which the joint that connects the ball of the arm bone (humeral head) to the shoulder blade socket (glenoid) has damaged or worn out cartilage. Normally the ends of the bone are covered with hyaline articular cartilage , a surface so smooth that the friction at the joint is less than that of an ice ...
While the Latarjet procedure can be used for surgical treatment of most cases of shoulder dislocations or subluxation, it is particularly indicated in cases with bone defects. [4] The failure rate following arthroscopic Bankart repair has been shown to dramatically increase from 4% to 67% in patients with significant bone loss. [ 5 ]
The bone formation portion (σ f) of the bone remodeling period is calculated as follows: [5] = in which MWT refers to the mean wall thickness of the completed bone unit and M f refers to the prevailing mean effective bone appositional rate. In other words, what this formula means is that the bone remodeling period is equivalent to the ...
