Core decompression may used in the management of early stage, precollapse nontraumatic osteonecrosis of the humeral head. We propose a technique without risk of complications associated with injury to the biceps tendon or the blood supply to the humeral head.

Editorial Commentary: Partial Rotator Cuff Repair and Deltoid Retraining Shows Positive Outcomes for Large to Massive Rotator Cuff Tear.
Arthroscopy
January 2025
Department of Orthopaedic Surgery, New England Baptist Hospital, Boston, MA USA. Electronic address:
In terms of rotator cuff repair, there is a goal for complete repair and healing, as rotator cuff integrity correlates with clinical and functional results. Retear has been shown to have a significant influence on progression toward osteoarthritis, and patients with an intact supraspinatus show superior abduction and flexion strength. However, in cases where complete repair may not be possible and/or cost limitations may prohibit augmentation, partial repair can provide a respectable outcome.

BMC Surg
January 2025
Department of Orthopedics, General Hospital of Southern Theater Command of PLA, Guangzhou, 510000, People's Republic of China.
Objective: To compare the clinical efficacy of the minimally invasive lateral shoulder approach and deltopectoral space approach in the treatment of proximal humerus fractures.
Methods: The clinical data of 95 patients with proximal humerus fractures admitted to the hospital from June 2018 to June 2023 were retrospectively collected. Forty-four patients were treated with a minimally invasive lateral shoulder approach (study group), and 51 patients were treated with a deltopectoral space approach (control group).
Comparative anatomy of the subclavius muscle and clavicle: a histological study using human, swine and mouse fetuses.
Folia Morphol (Warsz)
January 2025
Department of Histology and Developmental Biology, Tokyo Dental College, Tokyo, Japan.
Background: Some mammals including the swine carry a fibrous vestigial clavicle, but a subclavius muscle (SBM) extends between the first rib and the supraspinatus muscle surface fascia. We aimed to examine development of the SBM and clavicle for finding a specific factor to provide the curious morphology.
Materials And Methods: Histological sections of early- and midterm fetuses of the swine, human and mouse were observed and compared at the almost same morphological stage.
Humeral Head-Split Fracture in Two Dogs.
Vet Radiol Ultrasound
January 2025
Royal (Dick) School of Veterinary Studies and Roslin Institute, The University of Edinburgh, Roslin, UK.
Two skeletally immature female dogs were each investigated for chronic weight-bearing thoracic limb lameness. The first patient was lame for 2 months following a tumble whilst playing, and the second patient had been intermittently lame since 3 weeks of age. In both cases, radiographic examination of the shoulder revealed fissuring of the caudal humeral head consistent with an incomplete proximal humeral Salter-Harris type IV fracture with an Enoki-mushroom-like appearance of the caudal fragment, where two heads rise from a common stem.

Cureus
December 2024
Trauma and Orthopaedics, Northampton General Hospital, Northampton, GBR.
Although mixing and matching components is a common, safe, and well-documented practice in hip revision surgery, our extensive search indicates that it has not been previously reported for shoulder arthroplasty. This case report presents the use of mixed implants in shoulder revision surgery to reduce morbidity and address flaws in the initial implant design. We describe a case of a patient with multiple epiphyseal dysplasia who was treated for osteoarthritis in his left shoulder with an anatomic shoulder replacement in 2014.
