BACKGROUND We reviewed our results and complications of using a pre-bent 1.6 mm Kirschner wire (K-wire) for extra-articular metacarpal fractures. The surgical procedure was indicated for angulation at the fracture site in a true lateral radiograph of at least 30 degrees and/or in the presence of a rotatory deformity. METHODS A single K-wire is pre-bent in a lazy-S fashion with a sharp bend at...

INTRODUCTION Tuberculous involvement of metacarpals and phalanges is a rare presentation of extrapulmonary tuberculosis in adult. Tuberculous infection of the metacarpals, metatarsal and phalanges of hands and feet is known as tubercular dactylitis. CASE REPORT A 65 years old female with history of pain and swelling at 1st metacarpal of left hand, since 3 months which gradual in onset and pro...

A man aged fifty mangled his non-dominant left hand in a spinning machine (Fig. 1). At the time of primary operation the condition of the hand was as follows. The thumb had been severed through the base of the proximal phalanx. The index finger had been severed through the proximal part of the shaft of the metacarpal; the palmar skin remained but was not viable. The middlefinger had a compound ...

INTRODUCTION Isolated trapezium fractures accounts for 3-5% of all carpal fractures, are often missed on initial presentation. Trapezial fractures should be treated early given its importance in grip and pinch. We report a rare isolated coronal fracture of trapezium, following fall on an outstretched hand. CASE REPORT A 40-year-old right lady presented with pain in right hand due to fall on o...

During dissection practice held at Kyorin University School of Medicine in 2004, two anomalous muscles were observed on the Rt-forearm-flexor-side of an 83-year-old man. The results of this investigation are reported. One accessory muscle originated from the tendinous insertion of the biceps brachii and medial epicondyle. After passing through the deep layer of the pronator teres, it became ten...

PURPOSE Ulnar-sided carpometacarpal injuries can be difficult to diagnose radiographically. We hypothesized that the resting position of the normal hand during lateral radiography provides a consistent relationship between the rays and that dorsal subluxation of the metacarpal base in fracture-dislocations increases the angle between the uninjured index and long metacarpals and the injured smal...

INTRODUCTION Isolated pure dislocation of the fifth carpometacarpal (CMC) joint is a very rare injury and classified depending on displacement of the metacarpal base. This rare injury is often difficult to recognize and is liable to be overlooked. The purpose of this case report is to present a patient with an isolated dislocation of the fifth CMC joint that was satisfactorily treated with clos...

To measure the motions of the trapeziometacarpal joint of the thumb quantitatively, a roentgenographic method was developed and tested using T-shaped metal markers, a special cassette-holder, and biplane roentgenograms. Two experiments were performed. In the first one, the metal markers were fixed to the trapezium and third metacarpal in ten cadaver specimens, and a fixed spatial relationship b...
