Introduction: Anatomic unconstrained arthroplasty for the treatment of proximal humeral nonunion is challenging and may require management of rotator cuff tearing or scarring, glenohumeral instability, shoulder capsule fibrosis, poor bone quality and bone defects, and glenohumeral arthritis and may require internal fixation and bone-grafting for stimulation of healing.

Step 1 Preoperative Planning: Obtain anteroposterior, axillary, and lateral scapular Y views of the shoulder to assess the fracture for the size and position of the humeral head, humeral shaft, and greater and lesser tuberosities as well as for fracture nonunion.

Step 2 Positioning And Surgical Approach: In cases with substantial contracture or difficult exposure, use an anteromedial approach. Read More

Treatment of young, active patients with primary glenohumeral osteoarthritis (GHOA) is challenging because shoulder arthroplasty may not be ideal in this population. In the past two decades, joint-preserving arthroscopic management options for GHOA, including débridement, have been used to treat different pathologies related to GHOA to reduce pain, to improve function, and to delay or even avoid arthroplasty. Key aspects of comprehensively addressing GHOA arthroscopically include chondroplasty, synovectomy, loose body removal, humeral osteoplasty with excision of the goat's beard osteophyte, capsular release, subacromial and subcoracoid decompression, axillary nerve decompression, and biceps tenodesis.

Glenohumeral arthritis in the young, active patient remains a challenging problem shoulder surgeons face. Anatomic total shoulder arthroplasty has been proven to be a successful operation for patients with end-stage shoulder arthritis; however, concerns over long-term implant survival remain. These concerns are amplified in young patients and largely revolve around the placement of a glenoid component, which is seen as the "weak link" in shoulder arthroplasty. Read More

Younger patients with severe glenohumeral (GH) arthritis are a challenge to treat, as they have high physical demands, high expectations, a long lifespan, and often altered anatomy from prior surgery or congenital deformity. Nonoperative management is the cornerstone of treatment; however, when it fails, shoulder arthroplasty can be indicated. Although the literature suggests that total shoulder arthroplasty is the most appropriate for severe GH arthritis, there are a subset of patients in which a hemiarthroplasty can still be successful.

Glenohumeral osteoarthritis in the young patient (aged <60 years) is a difficult condition, given both age and functional demands. Primary osteoarthritis is the most common etiology in this patient demographic, but secondary causes include osteonecrosis, previous trauma (eg, fracture-dislocation), previous infection (eg, septic arthritis), previous capsulorrhaphy, previous arthroscopic surgery (eg, chondrolysis), and glenoid dysplasia. Nonsurgical modalities, including activity modification, pharmacotherapy, physical therapy, and intra-articular injections, are the mainstay of management; however, in young patients who have exhausted nonsurgical management, surgical options include arthroscopic débridement, humeral head replacement with or without glenoid treatment (ie, biologic glenoid resurfacing, glenoid reaming), and total or reverse total shoulder arthroplasty.

Purpose: The purpose of this study was to compare clinical outcomes and development of post-infectious arthritis of the shoulder joint after single (Group S) or repeated (Group R) arthroscopic debridement surgeries. We hypothesized that (1) repeated surgeries might be attributable to initial subchondral involvement resulting from septic arthritis and (2) the repeated surgery group would exhibit a higher incidence of post-infectious arthritic changes and inferior clinical outcomes due to prolonged resolution of the infection.

Methods: This study included 42 patients (single surgery, n = 29; repeated surgery, n = 13) who underwent arthroscopic debridement for septic arthritis and had a minimum of 2 years of postoperative follow-up data. Read More
