INTRODUCTION Palmaris longus and flexor digitorum superficialis of the little finger are highly variable anatomically. The tendons vary in different parts of the globe and different regions of the same country. Many studies have negated an association between the tendons. However, most of the studies have a sample size of less than 500 subjects. AIMS AND OBJECTIVES The aim was to study the te...

BACKGROUND Current examination methods to assess the anatomical variations of flexor digitorum superficialis (FDS) tendon in the little finger necessitate a strong external force applied by the examiner and cause false negatives. A new examination method was designed to detect the variations more accurately. METHODS We examined the little fingers of 220 adult hands (110 subjects) by 2 methods...

A contraction and relaxation strategy with regard to forearm muscles during the release of the bowstring has often been observed during archery, but has not well been described. The purpose of this study was to analyze this strategy in archers with different levels of expertise; elite, beginner and non-archers. Electromyography (EMG) activity of the M. flexor digitorum superficialis and the M. ...

An avulsion of the flexor digitorum profundus (FDP) tendon from its insertion is typically described as a jersey finger. The patient in this case presented with pain and loss of motion of his dominant ring finger after grasping the jersey of an opposing American football player in an attempt to tackle him. This mechanism is typical of a jersey finger; however, his injury included avulsions from...

We report a case of post-traumatic trigger finger due to a partial longitudinal tear of the flexor digitorum superficialis. The suspect came from the clinical history and the young age of the patient. It was successfully treated with tendon flap suture and pulley A1 release.

Blind intramuscular injection might cause severe neurovascular injury if it would be performed with insufficient knowledge of anatomy around the injection area. We report a case of pseudo-anterior interosseous syndrome caused by multiple intramuscular steroid injections around the antecubital area. The patient had weakness of the 1st to 3rd digits flexion with typical OK sign. Muscle atrophy wa...
