Glenohumeral osteoarthritis has proven to be a major contributor to shoulder joint pain and dysfunction in the elderly. There are several conditions about the shoulder that contribute to the development of glenohumeral osteoarthritis, which includes traumatic injuries, rotator cuff pathology, glenohumeral instability, glenoid dysplasia, and osteonecrosis. When glenohumeral osteoarthritis pain is refractory to conservative treatment, intra-articular injections and surgery can be performed. Read More

While short stems in total shoulder arthroplasty (TSA) preserve bone stock and facilitate revision surgery, they have been associated with higher rates of malalignment and loosening in some cases compared to standard length stems. The purpose of this study was to analyze the intramedullary canal in progressive increments distal to the greater tuberosity to provide anatomic information about the optimal length of press-fit short stems for alignment and stability in TSA. We hypothesized that the humeral canal diameter will remain variable for the first 50 to 75 mm distal to the greater tuberosity and will become consistent thereafter. Read More

Department of Orthopaedic Surgery, Massachusetts General Hospital, Harvard Medical School, Boston, MA, USA.

Background: Patient-reported outcome measures (PROMs), including the Patient-reported Outcomes Measurement Information System (PROMIS), are increasingly used to measure healthcare value. The minimum clinically important difference (MCID) is a metric that helps clinicians determine whether a statistically detectable improvement in a PROM after surgical care is likely to be large enough to be important to a patient or to justify an intervention that carries risk and cost. There are two major categories of MCID calculation methods, anchor-based and distribution-based. Read More

Avascular necrosis (AVN) of the humeral head is debilitating condition that, when left untreated, can progress to humeral head collapse and end-stage arthritis of the glenohumeral joint. Core decompression is widely regarded as a first-line surgical treatment for early-stage AVN, and when performed on the appropriate patient, core decompression is an effective treatment for improving symptoms and preventing progression and humeral head collapse. This article discusses operative indications and presents a relatively simple and effective arthroscopic method for core decompression of humeral head avascular necrosis. Read More

Department of Orthopaedic Surgery, Johns Hopkins University, Baltimore, Maryland, USA.

Aims: Corticosteroid injections are often used to manage glenohumeral arthritis in patients who may be candidates for future total shoulder arthroplasty (TSA) or reverse shoulder arthroplasty (rTSA). In the conservative management of these patients, corticosteroid injections are often provided for symptomatic relief. The purpose of this study was to determine if the timing of corticosteroid injections prior to TSA or rTSA is associated with changes in rates of revision and periprosthetic joint infection (PJI) following these procedures.

Bone & Joint Center, Henry Ford Health System, Detroit, Michigan, USA.

Background: Rotator cuff repair is a common orthopaedic procedure that provides pain relief for many patients, but unfortunately, an estimated 20% to 70% of repair procedures will fail. Previous research has shown that elongation (ie, retraction) of a repaired tendon is common even in patients with a repair construct that appears intact on magnetic resonance imaging. However, it is unknown how this repair tissue functions under dynamic conditions. Read More

Purpose: Symptomatic carpal tunnel syndrome in patients with advanced ipsilateral glenohumeral arthritis requiring total shoulder arthroplasty (TSA) may be easily overlooked. Even when diagnosed beforehand, most upper extremity surgeons have historically chosen to perform TSA and carpal tunnel release (CTR) separately. We hypothesized that combined single-stage TSA and CTR is feasible and yields results comparable with those when the 2 procedures are performed separately, while avoiding 2 surgeries. Read More

Shoulder arthroplasty has become an increasingly common option for the management of glenohumeral osteoarthritis in younger, higher demand, and athletic individuals. Patients with shoulder arthritis in whom nonsurgical measures fail and who are not candidates for arthroscopic treatment may be evaluated for shoulder arthroplasty. Available options include shoulder hemiarthroplasty, with or without biologic glenoid resurfacing, total shoulder arthroplasty, and less commonly reverse total shoulder arthroplasty. Read More

Instr Course Lect 2022 ;71:135-144

Glenohumeral arthritis in athletes or young and active individuals constitutes a challenging clinical problem, and multiple factors should be taken into consideration when deciding on nonsurgical or surgical treatment in this patient cohort. Selection of therapy should be based on clinical evidence, but the therapeutic strategy should align with patient expectations. Patient education on the nature and progression of shoulder osteoarthritis may facilitate the decision-making process regarding the selection of treatment. Read More

Arthroscopy 2022 03;38(3):699-700

Massive irreparable rotator cuff tears without glenohumeral arthritis are a common cause of shoulder pain and disability. Many surgical treatment options have been proposed, including debridement, partial repair, tendon transfer, superior capsule reconstruction, balloon spacer placement, bursal acromial reconstruction, and reverse shoulder arthroplasty. Interposition graft bridging reconstruction, as evidenced by the mid-term results of the current study, may also be considered, at least for now. Read More

Limited clinical evidence is available to help to predict poor outcomes after reverse shoulder arthroplasty (RSA) among patients with massive rotator cuff tears without glenohumeral arthritis. A retrospective case-control study was performed for patients who underwent RSA for massive rotator cuff tear without glenohumeral arthritis (Hamada score ≤3) and had a minimum of 2 years of follow-up. Preoperative risk factors for poor outcomes were subsequently analyzed. Read More

Bull Hosp Jt Dis (2013) 2022 Mar;80(1):37-46

Glenohumeral osteoarthritis (GHOA) in the young adult remains a challenging clinical problem to treat. These difficulties stem from the high physical demands and expectations of this patient population, limited longevity of existing treatment modalities, and need for a future revision surgery after primary surgical intervention. Given the heterogeneous etiology, clinical presentation, and radiographic findings, a thorough understanding of the pathology, patient expectations, and outcomes of existing treatment options available is necessary to deliver a treatment that is tailored to individual needs of the patient.
