Osteochondral lesions (OCLs) that are frequently encountered in skeletally immature and adult patients are more common than once thought, and their incidence rate is rising. These lesions can appear in many synovial joints of the body, such as the shoulder, elbow, hip, and ankle, occurring most often in the knee. The term osteochondral lesion includes a vast spectrum of pathologies such as osteochondritis dissecans, osteochondral defects, osteochondral fractures, and osteonecrosis of the subchondral bone.

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.

»: The majority of proximal humeral fractures (PHFs) in patients who are ≥65 years of age are treated nonoperatively, but certain complex fracture patterns benefit from surgical intervention. However, there continues to be debate regarding the indications for surgery and the optimal surgical treatment (repair versus replacement) in this population.
»: Reverse total shoulder arthroplasty (RTSA) has grown in popularity for surgical treatment of fracture-dislocations and displaced complex PHFs in patients who are ≥65 years of age; it has definite advantages over surgical repair and hemiarthroplasty, but this finding requires additional higher-quality evidence.

Introduction: Dysbaric osteonecrosis (DON) is a specific type of atraumatic osteonecrosis that has been shown to occur mainly in deep-sea divers and workers exposed to increased air pressure environments. The pathophysiology is not entirely understood but is thought to be due to subclinical decompression sickness resulting in arterial gas emboli. This leads to vascular occlusion and subsequent bone death.

Background: Adolescent idiopathic scoliosis (AIS) is the most common form of abnormal spine curvature observed in patients age 10 to 18. Typically characterized by shoulder height and waistline asymmetry, AIS may drive uneven distribution of force in the hips, leading to increased rates of concurrent hip diagnoses. The relationship between AIS and concurrent hip diagnoses is underexplored in the literature, and to date, there has been little research comparing rates of hip diagnoses between patients with AIS and those unaffected.

Background: Avascular necrosis (AVN) of the humeral head is a debilitating pathology that can be managed with an array of treatments depending on disease staging. Humeral head arthroplasty for AVN has demonstrated good short-term improvements in pain and range of motion, but the published long-term outcomes data are limited. The objective of this study was to report long-term survivorship and outcomes for patients undergoing hemiarthroplasty (HA) or total shoulder arthroplasty (TSA) for the treatment of AVN of the humeral head.

Background: Claims of shoulder injury now account for half of all claims to the Vaccine Injury Compensation Program. Reports from databases of claims or potential adverse events note a relatively high mean age and high prevalences of rotator cuff tendinopathy and adhesive capsulitis-common shoulder problems that might be incidental to vaccination. Published case reports provide much more detail about individual patients than is available in databases.

The humeral head is considered the second most common site for osteonecrosis to occur after the femoral head. As seen in the femoral head, the circulatory implications characteristic of this condition are attributable to the interaction between a genetic predisposition and the exposure to certain risk factors. There is no consensus regarding the pathogenesis of osteonecrosis, yet the final common pathway results in disrupted blood supply, increased intraosseous pressure, and bone death.

Background: Massive rotator cuff tears associated with greater tuberosity bone loss are challenging to treat. Repairing the rotator cuff without addressing the greater tuberosity deficiency may result in poorer clinical outcomes.
Hypothesis: Utilizing an Achilles tendon-bone block allograft to address both the massive rotator cuff tear and greater tuberosity bone loss concurrently can result in improved clinical outcomes.

Anatomic total shoulder arthroplasty is the replacement of the humeral head and glenoid surfaces with the goal of replicating normal anatomy. It is commonly utilized for patients with osteoarthritis, rheumatoid arthritis, and osteonecrosis, who have decreased range of motion (ROM), persistent pain, and loss of strength. Total shoulder Arthroplasty (TSA) is the third most common joint replacement in the United States.

Aims: Open reduction and plate fixation (ORPF) for displaced proximal humerus fractures can achieve reliably good long-term outcomes. However, a minority of patients have persistent pain and stiffness after surgery and may benefit from open arthrolysis, subacromial decompression, and removal of metalwork (ADROM). The long-term results of ADROM remain unknown; we aimed to assess outcomes of patients undergoing this procedure for stiffness following ORPF, and assess predictors of poor outcome.
