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.

Complex Lesions

Complex dorsal metacarpophalangeal (MCP) joint dislocations as a result of hyperextension injuries are uncommon in the pediatric population and irreducible to closed maneuvers. Treatment of these complex lesions is invariably surgical, and dorsal or volar approaches are traditionally used. The authors describe a case of a 16-year-old male who suffered a fall onto his outstretched right hand in a soccer game. The patient presented to the ER with pain and deformity of the index finger MCP joint. Radiographs confirmed a complex MCP dislocation with a small osteochondral fragment. A lateral surgical approach was made, and interposition of the volar plate and an osteochondral fragment blocking the reduction were found. This versatile approach allowed access to volar and dorsal structures, minimizing the risk of surgical scarring and mobility arch limitation. To our knowledge, there are no reported cases regarding a lateral surgical approach.

The Right

A 21 year-old woman with achondroplasia exhibited locking of the metacarpophalangeal joint of the right index finger which required surgery to release the joint. Locking was confirmed to be due to entrapment of the fan-like part of the radial collateral ligament on a metacarpal head prominence arising from epiphysial thickening.

Definitive Management

Complex dislocation of the metacarpophalangeal joint of the index finger is rare and often requires surgical intervention. Here, we present a case of an index finger metacarpophalangeal joint dislocation requiring open reduction due to obstruction by a displaced volar plate and the intra-articular entrapment of a sesamoid bone. Surgical approach was performed dorsally, allowing easy visualization of the volar plate and sesamoid bone as well as minimizing risk to the radial digital nerve to the index finger. Postoperatively, the patient reported good functional return despite the delay in definitive management.

We developed a new internal fixation method for extra-articular fractures at the base of the proximal phalanx using a headless compression screw to achieve rigid fracture fixation through a relatively easy technique. With the metacarpophalangeal joint of the involved finger flexed, a smooth guide-pin is inserted into the intramedullary canal of the proximal phalanx through the metacarpal head and metacarpophalangeal joint. Insertion tunnels are made over the guide-pin using a cannulated drill. Then, a headless cannulated screw is placed into the proximal phalanx. All of five fractures treated by this procedure obtained satisfactory results.

Movement Tracking

The purpose of this study was to examine the effects of age, sex, and hand preference on precise control of voluntary movement at the index finger metacarpophalangeal joint in able-bodied volunteers. An electrogoniometer was attached to this joint and connected to a computer. The computer screen displayed a sine wave target that each subject attempted to track with careful extension and flexion finger movements. Accuracy index scores were calculated for the extension phases, flexion phases, and the total sine wave. Each subject performed three tracking trials and the average for each of the above scores was computed. The results showed that younger subjects tracked significantly more accurately than older subjects and men tracked significantly more accurately than women. Also, the subjects tracking with the nonpreferred hand (15 right, 105 left) tracked significantly more accurately than those subjects tracking with the preferred hand (112 right, 8 left) in the flexion phases of the test. The data from these able-bodied subjects provide a base for comparison of patients' data, which may be helpful in the early recognition and monitoring of problems with precision in movement control.
