Peripheral neuropathy following monkeypox infection: an unexpected diagnosis of Parsonage-Turner syndrome Open
Parsonage-Turner syndrome following monkeypox infection is a rare form of peripheral neuropathy seen in orthopaedic practice and described only once in the literature. We present the case of a man in his 30s with severe shoulder pain and s…

Three-dimensional evaluation of the transverse rotator cuff muscle's resultant force angle in relation to scapulohumeral subluxation and glenoid vault morphology in nonpathological shoulders Open
Despite an assumed balance in the transverse volume of the rotator cuff muscles in nonpathological shoulders, variations exist regarding the transverse resultant force depending on the SHSI, GVA, and GOA. In healthy/nonosteoarthritic shoul…

EP133 Single-bolus injection of local anaesthetics, with or without continuous infusion, for interscalene brachial plexus block in the setting of multimodal analgesia: a randomised controlled trial Open
Background and Aims Previous trials favoured a continuous interscalene brachial plexus block over a single injection for major shoulder surgery. However, these trials did not administer a multimodal analgesic regimen. The null hypothesis o…

The role of platelet-rich plasma in shoulder pathologies: a critical review of the literature Open
Platelet-rich plasma (PRP) is a revolutionary treatment that harnesses the regenerative power of the body's own platelets to promote healing and tissue regeneration. While PRP therapy has emerged as a promising option for augmenting biolog…

Muscle co-contraction in an upper limb musculoskeletal model: EMG-assisted vs. standard load-sharing Open
Estimation of muscle forces in over-actuated musculoskeletal models involves optimal distributions of net joint moments among muscles by a standard load-sharing scheme (SLS). Given that co-contractions of antagonistic muscles are counterpr…

Feasibility of an alternative method to estimate glenohumeral joint center from videogrammetry measurements and CT/MRI of patients Open
Videogrammetry is commonly used to record upper limb motions. However, it cannot track the glenohumeral joint center (GH). GH is required to reconstruct upper limb motions. Therefore, it is often estimated by separately measuring scapular …

Agenesis of the long head of the biceps brachii tendon: ignored variations of the anatomy and the next tendon to disappear? Open
Bilateral agenesis of the long head of the biceps brachial tendon (LHB) is a very rare variation of the anatomy. We report a case of an 18-year-old man with bilateral agenesis of the long head of the biceps brachii tendon. We present initi…

A randomised controlled trial of shoulder block vs. interscalene brachial plexus block for ventilatory function after shoulder arthroscopy Open
Summary The shoulder block may impair ventilatory function and diaphragmatic movement less than the interscalene brachial plexus block. We randomly allocated 30 adults who underwent shoulder arthroscopy under general anaesthesia to ultraso…
