An 18-year-old man with cerebral palsy presented with a flexion deformity of the middle finger particularly at the metacarpophalangeal joint and ulnar dislocation of the extensor tendon. Releasing the tight ulnar sagittal band and imbricating the attenuated radial sagittal band allowed centralization of the extensor tendon. For complete correction of other deformities intrinsic release and extrinsic flexor muscle lengthening were done. Extensor tendon instability in this case was due to the combined forces of the extrinsic and intrinsic muscles on the retinacular system of the extensor mechanism.

The Difference

A tendon subluxation test was performed on the unaffected side in 13 patients with traumatic extensor tendon dislocation of the middle finger and on both middle fingers in 800 healthy controls to identify extensor mechanism laxity at the metacarpophalangeal joint. Ten of the 13 patients with dislocation had laxity of middle finger extensor tendon, compared with 174 of the 800 (22%) controls. The difference in these rates of extensor tendon laxity is significant ( P<0.0001), and suggests that extensor mechanism laxity at the metacarpophalangeal joint may predispose to traumatic extensor tendon dislocation.

Intrinsic Muscles

A case with spontaneous extensor tendon dislocation was treated operatively. Right hand was more severely affected with contracture of the metacarpophalangeal joints. Centralisation of the extensor tendons and sectioning of ulnar intrinsic muscles sufficed correction of the pathology. No recurrence occurred in the last 24 months.

Juncturae Tendinum

A 43-year-old female shiatsu therapist complained of sudden snapping of the metacarpophalangeal joints (MCPjs) of both ring fingers during a specific hand posture. The extensor tendon of the ring finger was dislocated ulnarly when the MCPj of the ring finger was flexed and deviated ulnarly and the MCPj of the middle finger was extended. Surgical exploration revealed an attenuated radial sagittal band. We plicated the juncturae tendinum of the extensor digitorum communis between the middle and ring fingers and released the ulnar sagittal band partially to centralise the extensor tendon excursion. Twenty-six months postoperatively, the patient regained full active and passive range of motion of all fingers without extensor tendon dislocation or snapping in either hand during work.

Alternative Method

We report a case of extensor tendon dislocation at the metacarpophalangeal joint of the middle finger in which it appeared that an ulnar translation force created by an end-to-side transfer contributed to the dislocation. We recommend alterations in technique or alternative method of extensor tendon reconstruction to avoid this complication if unfavorable factors for end-to-side transfer exist.

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.

Primary Assessment

Irreducible volar subluxation should be considered when assessing a patient with flexion deformity of the proximal interphalangeal finger joint (PIPJ). Primary assessment requires careful examination of the collateral ligaments and extensor tendon. Preoperative imaging such as ultrasound and MRI can help identify the interposed structures and plan the subsequent operation. Although rare, irreducible volar subluxation due to radial collateral ligament interposition is an important entity to be aware of. Prompt and appropriate management can prevent joint stiffness and loss of function.
