Variation in the origin of long flexor tendons in the anterior compartment of forearm is common. During routine cadaveric dissection at Melaka Manipal Medical College (Manipal Campus), we observed a separate muscle belly and tendon of flexor digitorum superficialis (FDS) to the fifth digit in the right upper limb of a 60 year-old male cadaver. The anomalous muscle belly originated from the common flexor tendon from the medial epicondyle of the humerus and continued as a thin tendon at the middle of the forearm to get inserted into the middle phalanx of the fifth digit. This can be considered as a case of split flexor digitorum superficialis. Such muscle variations and knowledge of their frequency, appearance, and location can be helpful for surgeons.

Throughout childhood growth and development, both the nervous and the musculoskeletal systems undergo rapid change. The goal of this study was to examine the impact of growth-related changes in skeletal size and muscle strength on the neural control of finger force generation. By modifying an existing OpenSim hand model in accordance with pediatric anthropometric data, we created 10 distinct models representing males and females at each year of development from 6 to 10 years old.

Sarcopenia corresponds to a decrease in muscle mass and strength. CCL5 is a new myokine whose expression, along with the CCR5 receptor, is increased in sarcopenic muscle. Therefore, we evaluated whether CCL5 and CCR5 induce a sarcopenic-like effect on skeletal muscle tissue and cultured muscle cells.

Background: Quantitative ultrasound imaging is a popular technique to assess the structural properties of the intrinsic and extrinsic foot muscles. Although several studies examined test-retest reliability, specific gaps remain in assessing inter-rater reliability, particularly distinguishing between image acquisition and muscle measurement. Additionally, these studies utilized equipment that may not be generalizable across both clinical and research settings and often involved small sample sizes without prior sample size calculations.

This study investigates the effects of photobiomodulation (PBM) with a 660-nm laser on nerve regeneration and muscle morphometry following median nerve axonotmesis in rats. Sixteen Wistar rats were divided into a control group and laser-treated group, with the latter receiving 10 applications of PBM (660 nm; 20 mW; 10 J/cm; 0.4 J; and 20 s) over 2 weeks.

Dynamic compression of the median nerve under the lacertus fibrosus at the elbow causes pain and weakness. It is a frequently overlooked pathology and a cause of failed recovery after carpal tunnel release. The purpose was to present a technical note on minimally invasive ultrasound-guided lacertus syndrome surgical treatment under WALANT.
