Objective: To objectively evaluate the effect of transecting the tendon of the biceps brachii muscle (BBT), tendon of the infraspinatus muscle (IFS), or medial glenohumeral ligament (MGHL) on shoulder joint stability in canine cadavers.
Sample Population: 81 forelimbs from mature dogs.
Procedure: Cadaver forelimbs were placed in a testing frame and axially preloaded with 4 kg of weight. Shoulder joint stability was tested in neutral joint position, flexion, and extension before and after transection of the BBT (n = 37), IFS (37), or MGHL (7). Humeral translation relative to the glenoid was induced by applying a 3-kg load in each of 3 directions (cranial, lateral, and medial) and quantitatively measured by use of an electromagnetic motion tracking system. Peak translational data were compared in each joint position before and after transection of the BBT, IFS, or MGHL.
Results: When tested in neutral position, the cranial, lateral, and medial translation of the humerus was significantly increased after BBT transection. In the flexed position, translation of the humerus in the cranial and lateral directions was significantly increased after BBT transection. In the extended position, the medial translation of the humerus was significantly increased after BBT transection. Complete medial luxation of all humeral heads occurred following transection of the MGHL.
Conclusions And Clinical Relevance: The BBT contributes to passive shoulder joint stability in dogs, particularly in the neutral and flexed positions. It also provides medial stability during shoulder joint extension. Complete luxation of the joint occurs when the MGHL is transected.

The diagnosis of septic arthritis remains challenging in the clinical setting, often leading to a suspicion for medical liability. Our purpose is to describe an unusual case of a post-mortem diagnosis of P. multocida fatal septic arthritis, in a healthy 67-year-old woman presenting with pain in the right shoulder.

: Shoulder pain is a common treatment outcome in breast cancer survivors. While various risk factors and mechanisms for shoulder pain have been proposed, evidence is inconsistent. Increased risk of subacromial pain syndrome exists, which can lead to disability and reduced quality of life if untreated.

The aim of this study was to analyze the outcomes of arthroscopic subscapularis tendon repair combined with coracoplasty in the treatment. The study involved 80 patients (46 males, 34 females; aged 33 to 73 years), who underwent arthroscopic repair for subscapularis tears (type I, II, and III) presenting symptoms of anterior shoulder pain and tenderness. Subcoracoid impingement was defined as a coracohumeral distance of less than 6 mm on preoperative magnetic resonance imaging, with a follow-up of was at least two years.

The ARCR_Pred study was initiated to document and predict the safety and effectiveness of arthroscopic rotator cuff repair (ARCR) in a representative Swiss patient cohort. In the present manuscript, we aimed to describe the overall and baseline characteristics of the study, report on functional outcome data and explore case-mix adjustment and differences between public and private hospitals. Between June 2020 and November 2021, primary ARCR patients were prospectively enrolled in a multicenter cohort across 18 Swiss and one German orthopedic center.

: Shoulder pain is a very common health issue among adults, being 8% due to calcifying tendinopathies (CT) of the shoulder. The evolutionary process of this lesion can be classified according to Bianchi Martinoli, depending on the ultrasound appearance. In 50% of cases, with first-line treatments, they resolve spontaneously.
