Little Finger

We managed a case of locked metacarpophalangeal joint of the little finger in the extension position. Incarceration of a chronic osteochondral fracture fragment led to this unique condition. The fracture fragment partially adhered to the volar plate and ulnar collateral ligament on the joint side, which is supposed to have resulted in manually irreducible locking of the joint. We performed open reduction and achieved release of the locked joint by excising the fracture fragment.

Little Finger

Kaplan’s lesions are defined as open wounds with the metacarpal head exposed in the palms, accompanied by complex dorsal dislocation of the metacarpophalangeal joint (MCPJ). Kaplan’s lesions are clinically rare because the volar side of the MCPJ is anatomically supported and reinforced by a stronger adjacent structure. Moreover, lesions in the little finger are very rarely reported because most Kaplan’s lesions occur in the index finger. The reduction of lesions and restoration of joint stability is difficult when Kaplan’s lesions occur. Various methods have been currently introduced in the treatment of Kaplan’s lesions; however, no standardized treatment has been established because of the rarity of this disease. This paper reports a case of Kaplan’s lesion of the left little finger without fracture after a fall; the case was successfully treated with open reduction using a volar approach.

Stener Lesion

We report a case of distal pull-off of the ulnar collateral ligament of the metacarpophalangeal joint of the thumb with two fracture fragments. The more obvious fracture fragment, seen on plain X-ray to be lying adjacent to the expected location of the attachment of the ulnar collateral ligament of the metacarpophalangeal joint of the thumb, was, in fact, unassociated with it and was part of the attachment of the adductor pollicis muscle. A second smaller fleck of bone which was attached to the displaced collateral ligament was only observed on plain X-ray on retrospective review. This second fleck of bone identified that this was a Stener lesion, requiring surgical reattachment of the ligament. Similar cases in the literature are reviewed and the use of MRI in detecting these lesions is discussed.

A patient with a volar dislocation of the metacarpophalangeal joint of the thumb is reported in which closed reduction proved impossible because of the interposition of the dorsal capsule, extensor pollicis longus tendon and extensor pollicis brevis tendon in the metacarpophalangeal joint. The collateral ligament was also ruptured. Therefore open reduction is recommended for similar cases.

Displaced Fracture

Ulnar collateral ligament injuries of the thumb may present as avulsion fractures of the bone or as ligamentous tears. Displaced fracture fragments or Stener lesions demand operative management. Occasionally, both fracture and ligamentous tears may occur simultaneously, and the management of the ligamentous aspect may be overlooked in cases with undisplaced fractures leading to failure of non-operative treatment. It is important in cases with a relatively undisplaced fracture fragment to exclude a simultaneous ligamentous tear and Stener lesion by careful clinical examination and by examining the radiographs for telltale displaced flecks of bone.

High Level

We report a case of rotatory subluxation of the metacarpophalangeal joint (MCPJ) of the finger. A 40-year-old man sustained an open injury to his index finger following an explosive injury. Radiographs showed rotatory subluxation of the index finger MCPJ. The index finger extensor digitorium was found interposed in the MCPJ, with a complete tear of the radial collateral ligament. Treatment was by open reduction and repair of the collateral ligament and the extensor tendon. A high level of clinical suspicion is needed to diagnose this entity.
