The suprascapular nerve (SSN) is commonly reconstructed by spinal accessory nerve (SAN) transfer. However, reinnervation of its branch to the infraspinatus muscle (IB-SSN) is poor. Reconstruction of the SSN in cases of scapular fractures is frequently neglected in clinical practice. The morphological study was performed on 25 adult human cadavers. The course and the length of SSN of minimal diameter of 2 mm within the trapezius muscle, the length of the distal stump of IB-SSN to its branching point and the length of the SSN available for reconstructive procedure were measured. The feasibility study of the SAN - IB-SSN neurotization performed by using a bony canal under the spine of scapula was performed. The mean distance of the SAN from the spine was 8.5 cm (±0.88) at the point where it perforates the trapezius muscle and 4.49 cm (±0.72) at the most distal part of the nerve. The mean length of the intramuscular portion of the nerve was 14.74 cm (±1.99). It ran under a mean latero-medial angle of 15.54 (±2.51). The mean distance between the medial end of the scapular spine and the SAN was 2.44 cm (± 0.64). The mean length of the IB-SSN was 3.6 cm (± 0.67). The mean length of the SAN stump which was mobilized from its original course and transferred to the infraspinous fossa to reach distal stump of the IB-SSN was 8.09 cm (±1.6). Direct SAN to IB-SSN transfer is anatomically feasible in the adult population.

Background/objective: Rheumatic diseases (RMDs) are among the leading health burdens and causes of disability globally. Interestingly, they are on the rise due to the increasingly ageing population. Inflammatory RMDs are not left behind in the rise, especially in Africa, where they were thought to be rare as there has been increasing reportage of these diseases in recent years.

Purpose: To determine if the fatty infiltration of rotator cuff muscles, as measured by magnetic resonance imaging (MRI) preoperatively and assessed using the Goutallier Fatty Degeneration Index (GFDI), can predict early post-operative shoulder stiffness (POSS) following rotator cuff repair (RCR).
Methods: This retrospective longitudinal cohort study included patients who underwent primary RCR, had available medical records, and underwent MRI before RCR between November 2012 and July 2022. Patients were excluded based on the following criteria: (1) preoperative shoulder stiffness, (2) additional procedures (e.

Unlabelled: Several medical conditions (diabetes, cardio-vascular diseases, hypercholesterolemia etc.) or modifiable behavioral habits (smoking habit and alcohol assumption) capable of causing a damage to the peripheral microcirculation are considered potential risk factors for degeneration/tear of the rotator cuff. The aim of the study was to analyse and quantify how the association of multiple known risk factors is more effective than the predisposing action of a single factor.

Background: Muscle atrophy after the rupture of a rotator cuff (RC) tendon is a major factor that increases the risk of secondary complications and re-rupture. Metformin, a type 2 diabetes treatment, can be used to modulate intracellular signaling pathways that promote muscle growth. This study aimed to verify whether systemic metformin administration could prevent supraspinatus (SS) atrophy after RC rupture in a rat model.
