Lower Socioeconomic Status Is Associated With Worse Preoperative Function, Pain, and Increased Opioid Use in Patients With Primary Glenohumeral Osteoarthritis.

Background: Numerous studies have identified differences in patient-reported outcome scores and complication rates based on various measures of socioeconomic status (SES); however, there is limited information regarding the role of SES in the shoulder arthroplasty cohort. The purpose of this study was to characterize the role of SES in patients undergoing primary anatomic total shoulder arthroplasty (TSA) for primary glenohumeral osteoarthritis (OA).

Methods: We identified 1,045 patients who had primary TSA done for OA in a prospective shoulder arthroplasty registry, and 982 patients met inclusion criteria.

Understanding the Importance of the Teres Minor for Shoulder Function: Functional Anatomy and Pathology.

Although the teres minor is often overlooked in a normal shoulder, it becomes a key component in maintaining shoulder function when other rotator cuff tendons fail. The teres minor maintains a balanced glenohumeral joint and changes from an insignificant to the most significant external rotator in the presence of major rotator cuff pathology. The presence or absence of the teres minor provides prognostic information on the outcomes of reverse total shoulder arthroplasty and tendon transfers.

The influence of critical shoulder angle on secondary rotator cuff insufficiency following shoulder arthroplasty.

Introduction: Secondary cuff failure after shoulder replacement is disabling and often requires additional surgery. Increased critical shoulder angle (CSA) has been found in patients with cuff tear compared to normal subjects. The interobserver reliability of the CSA and the relationship between CSA and symptomatic secondary cuff failure after shoulder replacement were investigated.

The treatment of type III acromioclavicular dislocations with a modified Cadenat procedure: surgical technique and mid-term results.

Introduction: The treatment of type III acromioclavicular injuries is controversial. Both conservative and surgical approaches have been successful. Aim of the present study was to prospectively evaluate the results of the modified Cadenat procedure in subjects with type III acromioclavicular joint injuries.

Chronic anterior glenohumeral instability in soccer players: results for a series of 28 shoulders treated with the Latarjet procedure.

Background: Glenohumeral instability is a common problem in young and active patients. Both open and arthroscopic procedures have proven to be effective options. In cases with large bone defects on the glenoid side or on the humeral head or in contact sports, arthroscopy leads to a high risk of recurrence.

Normalization of the subscapularis belly-press test.

The purpose of this report is to document the normal range of the subscapularis belly-press test and to define factors that influence it to aid in the assessment of subscapularis function in relevant shoulder pathology and procedures. Both shoulders in 204 patients with no history of shoulder problems were tested with an Isobex machine. Patients were educated on proper technique before testing.

Glenohumeral arthrosis in anterior instability before and after surgical treatment: incidence and contributing factors.

Background: Few large series of arthropathy related to anterior glenohumeral instability are available in the orthopaedic literature, preventing analysis of the incidence and the risk factors of preoperative and postoperative glenohumeral arthritis.

Hypothesis: Anterior stabilization surgery influences the risk factors of glenohumeral arthritis.

Study Design: Retrospective review.
