Background: The concept of on-track versus off-track bone lesions in glenohumeral instability continues to evolve. Although much has been ascertained from an original biomechanical model, bony pathological changes, especially on 3-dimensional (3D) imaging, have not been fully evaluated.
Purpose: To compare the differences in on-track versus off-track lesions to characterize glenoid and humeral head bone defects using 3D modeling software.
Acute coronary syndrome (ACS) remains a significant global health concern, with a growing recognition of its impact on young adults, particularly young female adults. Although gender-related factors, defined as a social construct that encompasses 4 distinct dimensions (gender roles, gender identity, gender relations, and institutionalized gender) are undoubtedly relevant across age groups, young female patients with ACS face specific challenges and disparities in outcomes, compared to other populations. This narrative review examines the role of gender-related factors-specifically, gender roles, gender identity, gender relations, and institutionalized gender-in influencing objective and subjective ACS outcomes in young female patients.

Though commercial three-dimensional preoperative planning software (3D PPS) is available to simulate ROM before and after OP resection, little is known about the magnitude of effect OPs and their subsequent removal have on simulated glenohumeral ROM.
Methods: Included patients were 1) indicated for reverse total shoulder arthroplasty (rTSA) using 3D PPS and 2) presented with glenoid and/or humeral head OPs on preoperative two-dimensional computed tomography (2D-CT) imaging.
Article Synopsis
- Humeral head reconstruction using fresh osteochondral allografts (OCA) is being explored as a viable option for treating shoulder stability issues, particularly due to the matching properties of talus bone grafts with joint surfaces.* -
- A controlled study using seven cadaver shoulders evaluated how talus OCA plugs affect the surface geometry of humeral heads with varying sizes of Hill-Sachs lesions (HSLs), showing significant improvements in surface area and congruency.* -
- Results indicated that while the native shoulder surface area was significantly lower, OCA augmentation notably increased surface area and congruency across all sizes of HSLs, confirming the effectiveness of talus OCA in shoulder reconstruction.*
Background: Engaging Hill-Sachs lesions (HSLs) pose a significant risk for failure of surgical repair of recurrent anterior shoulder instability. Reconstruction with fresh osteochondral allograft (OCA) has been proposed as a treatment for large HSLs.
Purpose: To determine the optimal characteristics of talus OCA bone plugs in a computer-simulated HSL model.
