Introduction Flexor digitorum superficialis (FDS) is the muscle which responsible from the skill actions of the fingers. It has three heads including humeral, ulnar and radial; generally the humeral and ulnar heads are fused together and called as humeroulnar head. The muscle fibers reach the other fingers except the thumb. Each of the muscle beams divides into two parts at the level of the 1st...

A 39-year-old gentleman presented with a painless finger mass that had increased in size over eight years. There was no history of trauma or injury. He denied having any numbness or tingling in his fingers. No similar masses were present elsewhere. Past medical and family histories were non-contributory. Physical examination revealed a non-tender soft mass on the extensor aspect of the right fi...

Objective: Fractures of metacarpals and phalanges are very common fractures, and there are a lot of treatment modalities. The purpose of the study was to describe the technique of percutaneous fixation of phalangeal fractures using a cannulated compression screw fixation system and its results. Methods: We conducted a prospective clinical study on 43 patients with different types of phalangeal ...

Fractures of the proximal interphalangeal joint constitute a broad spectrum of injuries. An understanding of the anatomy, the potential for joint instability, and the treatment options is essential to management of these fractures. Commonly observed fracture patterns involve one or both condyles of the proximal phalanx or the base of the middle phalanx. Fractures of the middle phalanx may invol...

795 aspect of the IP joint and the proximal phalanx of the right thumb. Both masses were solid, well-defined, and slightly tender. Mass was measured to be 2 cm on right thumb, 1.5 cm on left plantar region, respectively. On plain radiography of the right thumb, the mass showed a well-defined soft-tissue shadow. There were neither periosteal reactions nor articular involvement (Fig. 1). On plain...

The first dromaeosaurid theropod from the Lower Cretaceous Bayan Gobi Formation is identified based on an incompletely preserved partially-articulated left leg, increasing the known diversity of its understudied ecosystem. The leg belongs to specimen IVPP V22530 and includes a typical deinonychosaurian pedal phalanx II-2 with a distinct constriction between the enlarged proximal end and the dis...

We report a case of fingernails clubbing in a 55-year-old man suffered since the age of 40 from cutaneous psoriasis. The patient had no clubbing before and had no familial cases of clubbing. Cardiological and pneumological visits revealed no abnormalities. All laboratory tests were within normal limits and X-rays excluded the presence of pachyodermoperiostosis. We made the diagnosis of atypical...

Osteoid osteoma is a relatively common osteoblastic lesion of benign skeletal neoplasms and occurs most commonly in the cortex of long bones, especially the femur and the tibia. Radiological characteristics are a nidus that appears as a small, relatively radiolucent zone within an area of extensive reactive sclerosis. Clinically, the lesion presents with increasing pain, is worse at night, and ...

In human beings, the muscles of the sole of the foot are known to exhibit variations. During routine cadaveric dissection, an anomalous attachment of the flexor digiti minimi muscle was observed on both sides of a 55 year male cadaver. The flexor digiti minimi muscle had its usual origin from the plantar surface of base of the fifth metatarsal bone and the sheath of the peroneus longus muscle a...

Dynamic high-resolution ultrasonography findings obtained in 34 extreme rock climbers with finger injuries were compared with those in 20 healthy volunteers. Thicknesses of the flexor tendon and A-2 flexor tendon pulley system were measured at the base of the proximal phalanx. The distance between the tendon and phalanx was evaluated with the finger in extension and in forced flexion as a measu...
