During routine cadaveric dissection of the flexor compartment of the right arm, multiple supernumerary muscles were observed in a 56-year-old male cadaver. There were three supernumerary muscles took taking origin independently from the humerus distally to the insertion of coracobrachialis muscle. The upper two supernumerary muscles were attached to the common tendon of the biceps brachii muscle and considered as its additional heads. The third supernumerary muscle passed between the biceps brachii and brachialis muscles, then crossed obliquely the brachial artery and median nerve nearing cubital fossa to get inserted in to the radial side of the humeral head of the pronator teres. The clinical significance of the above variations is discussed (Fig. 1, Ref. 16).

: Anatomical variations in the biceps brachii muscle (BBM) are extremely frequent, leading to developmental and clinical implications. We studied the topography of the BBM and analyzed its correlations with other structures in the brachial region. A total of 103 cadaveric upper extremities were dissected.

Supernumerary extensor tendons of the hand are relatively common, whereas supernumerary extensor pollicis longus (EPL) tendons are rarely reported. Herein, we present the case of a 17-year-old boy with painful snapping at the anatomical snuffbox after repetitive pushups. Preoperative dynamic ultrasonography and magnetic resonance imaging revealed the bifurcation of EPL tendons.

Article Synopsis
- Phelan-McDermid syndrome (PMS) is a rare neurodevelopmental disorder linked to deletions of the 22q13 region, particularly affecting the SHANK3 gene, leading to various developmental challenges like intellectual disabilities and autism.
- Researchers conducted a study using the PMS International Registry to analyze clinical and genetic data from 401 individuals to understand how the size of deletions affects their clinical features.
- Findings revealed that larger deletions were associated with more severe developmental delays and physical issues, while individuals with smaller deletions or specific SHANK3 variants tended to show better self-help and verbal skills along with various psychiatric diagnoses.

Objectives: The prognostic value of left ventricular (LV) papillary muscle anomalies in dilated cardiomyopathy (DCM) patients is unclear. The objective of this study was to evaluate the prognostic significance of LV papillary muscle anomalies in DCM patients using cardiac magnetic resonance (CMR).
Methods: 369 DCM patients who underwent CMR at two Chinese medical facilities from January 2019 to June 2023 were retrospectively and consecutively included in total.

Wearable robots have promising characteristics for human augmentation; however, the the design and specification stage needs to consider biomechanical impact. In this work, musculoskeletal software is used to assess the biomechanical implications of having a two-degrees-of-freedom supernumerary robotic tail mounted posterior to the human trunk. Forward and backward tilting motions were assessed to determine the optimal design specification.
