Latissimus Dorsi Tendon Transfer and Reverse Shoulder Arthroplasty: Restoring Mechanical Advantage by Transfer Posterior to the Long Head of the Triceps Tendon.
J Shoulder Elbow Surg
December 2024
Shoulder and Elbow Division, Sports Medicine Institute, Hospital for Special Surgery, New York, NY, USA.
Background: Patients undergoing reverse shoulder arthroplasty (RSA) for rotator cuff arthropathy may present with an external rotation (ER) lag due to posterior rotator cuff insufficiency. As a result, the addition of a latissimus dorsi (LD) tendon transfer in combination with RSA has become increasingly utilized. Initial descriptions of LD tendon transfer involved rerouting of the LD tendon posterior to the long head of the triceps tendon.

Jakaya Kikwete Cardiac Institute, P.O. Box 65141, Dar es Salaam, Tanzania.
Background: Concurrent ST-elevation myocardial infarction (STEMI) and acute ischemic stroke (AIS) are extremely rare, and their management remains perplexing due to the absence of high-quality evidence and limited resources. For the first time, we report a rare, preventable, and suboptimally managed case of concurrent AIS and STEMI in a patient with non-Hodgkin lymphoma (NHL) who received cyclophosphamide, doxorubicin, vincristine, and prednisolone (CHOP) chemotherapy.
Case Presentation: A 59-year-old postmenopausal woman of African origin with a background history of type 2 diabetes mellitus presented to the Jakaya Kikwete Cardiac Institute with sudden onset of left-sided weakness and typical ischemic chest pain for 3 days.
Massive Bilateral Haemorrhagic Prepatellar Bursitis: A Case Report.
Cureus
November 2024
Department of Sports Medicine, Barts Health NHS Trust, London, GBR.
Prepatellar bursitis is a common cause of anterior knee pain. We present an unusual case of massive bilateral traumatic haemorrhagic prepatellar bursitis managed with surgical excision and describe our operative findings. The patient presented with large bilateral knee swellings which had been present for six years following a fall onto both knees.

Orthopaedic Biomechanics Laboratory, Congress Medical Foundation, Pasadena, CA, USA. Electronic address:
Background: There is a relative paucity of studies examining how the superior capsule reconstruction (SCR) may alter the kinematics of the glenohumeral joint capsule itself, specifically with respect to rotation and translation in the anterior-posterior and superior-inferior planes. This then raises the possibility that the SCR may be having unintended consequences on glenohumeral kinematics. The purpose of this study was to quantify the glenohumeral joint kinematics following Fascia Lata SCR (FL-SCR).

J Shoulder Elbow Surg
December 2024
Orthopedic Biomechanics Laboratory, Congress Medical Foundation, Pasadena, CA, USA. Electronic address:
Background: The restriction of active internal rotation (IR) after reverse shoulder arthroplasty (RSA) poses a challenging problem for reconstructive shoulder surgeons, particularly in patients suffering from massive rotator cuff tears (mRCT) with subscapularis (SSC) deficiency. This study aims to evaluate the biomechanical effectiveness of different tendon transfer techniques following medialized glenoid and lateralized humerus RSA in improving internal rotation (IR) strength.
Methods: Eight cadaveric shoulder specimens were evaluated using a custom shoulder testing system designed to simulate loading conditions typical of mRCT with SSC insufficiency.
