Digital neural loops are present in the palms of most individuals. They can arise within the common palmar digital nerves (CPDNs) or proper palmar digital nerves (PPDNs). Typically, common palmar digital arteries (CPDAs) pass through digital neural loops, however there are reports of loops forming around the superficial palmar arch or proper palmar digital arteries (PPDAs). We describe an unusual digital neural loop that involved both a CPDN and a PPDN. To our knowledge, this is the first…

Carpal tunnel syndrome caused by the entrapment of a bifid Lanz IIIA Type anatomical variant of median nerve: A case report and systematic literature review
A rare case of Lanz IIIA BMN Type at the wrist has been encountered in a patient with a CTS and a systematic review and practical considerations have been presented with the aim of raising awareness to the neurosurgical community of a such rare variant that could be encountered during carpal tunnel release procedures.

Digital neural loops: classification and implications of variation in hand surgery.
A new model, of separating neural loop position into anatomical levels, provides more information to the hand surgeon when dissecting and raising vascular pedicles for flaps reconstruction.
During a routine cadaveric dissection, an anatomical variation at the level of the right forearm of a 77-year-old Caucasian male cadavaver was observed, which was the third common palmar digital nerve running distally from the ulnar side of the median nerve and coursing through the flexor digitorum superficialis muscle.
The surgical anatomy of ulnar and median nerve communications in the palmar surface of the hand.
A risk area in which the communicating branch of the ulnar and median nerves may be subject to iatrogenic injury during common hand procedures is defined.

Carpal Tunnel Syndrome Caused by Bifid Median Nerve in Association with Anomalous Course of the Flexor Digitorum Superficialis Muscle at the Wrist
A rare case is reported in which an anomalous tendinous course of theflexor digitorum superficialis muscle is associated with bifid median nerve proximal to the flexor retinaculum at the distal wrist, causing clinical features of secondary carpal tunnel syndrome.
Cadaveric study of anatomical variations of the median nerve and persistent median artery at wrist
AHigh percentage of deviation from standard anatomy as well as a high percentage of transligamentous thenar muscle motor branch is shown in this study.
Ulnar to median nerve anastomosis in the palm (Riches-Cannieu anastomosis)
An unusual case of pure bilateral ulnar innervation of the thenar and hypothenar muscles of the hands and the anomaly known as Riches-Cannieu anastomosis should be kept in mind and should be investigated electrophysiologically.

During routine dissection classes to undergraduate medical students, the formation of each common palmar digital nerve divided into 2 or 3 branches and formed a ring enclosing the corresponding commonPalmar digital artery was observed.
Anatomic Variation of the Median Nerve Associated with an Anomalous Muscle of the Forearm
Abstract Documented anatomical variations are important not only for the study of the subject of anatomy, but also in clinical situation. This knowledge would aid surgeons in planning a preoperative
