A Case Report of Giant Cell Tumor in the Thumb Distal Phalanx.

Introduction: The following report describes a rare case of giant cell tumor (GCT) of the bone that presented in the distal phalanx of the thumb. GCT of the bone is a relatively rare, and typically benign condition that presents most frequently in the metaphysis of long bones in women age 30-50 years old. There are only three other instances in the literature describing GCT of the bone presenting in the distal phalanx of the thumb.

Patient with a Hook of the Hamate Fracture Presenting as Vascular Occlusion: Diagnosis Made with Bedside Ultrasound.

Background: Hook of the hamate fractures are particularly rare carpal fractures with significant morbidity if not diagnosed early. Classically, these fractures occur from localized blunt trauma to the hook of the hamate in racket sports. Common complaints include pain localized in the hypothenar eminence and reduced grip strength.

Anatomic variations of the first extensor compartment and abductor pollicis longus tendon in trapeziometacarpal arthritis.

Anatomic variation of the trapeziometacarpal joint stabilizing structures is one of the concepts proposed to explain the pathogenesis of trapeziometacarpal arthritis. We undertook this study to test the hypothesis that septation of the first extensor compartment or variation of the abductor pollicis longus (APL) tendon (supernumerary insertions) are more frequently associated with the progression or severity of trapeziometacarpal arthritis. Septation within the first extensor compartment was significantly associated with trapeziometacarpal arthritis (p = 0.

Reduction and maintenance of scapholunate dissociation using the TwinFix screw.

Objective: Closed reduction and internal fixation of the scapholunate dissociation are currently performed using K-wires or a headless bone screw. We present an alternative for this fixation by means of a cannulated screw with dynamic adjustable interfragmentary compression and discuss the advantages of using this type of technique.

Methods: Closed reduction of the scapholunate interval was achieved using a K-wire centered through the scaphoid and lunate bones followed by delivery of a cannulated compression screw to maintain the scapholunate interval.
