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.

Extensor Tendons

Finger extensor tendon dislocation at the metacarpophalangeal joint is caused by various etiologies, such as trauma, congenital anomaly, or rheumatoid arthritis. When the dislocation occurs with no etiology, this is called spontaneous dislocation. Although spontaneous extensor tendon dislocation in one, two or three fingers has been described, to our knowledge, simultaneous dislocation in four fingers has not been reported. In this paper, we report a spontaneous ulnar dislocation of all the extensor tendons in the index, long, ring, and small fingers. Repair of the radial sagittal bands of the extensor digitorum communis of the middle and ring fingers reduced dislocation of all the extensor tendons in four fingers.

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.

We report a rare case of radial dislocation of the extensor tendon over the metacarpophalangeal (MCP) joint of the thumb. Ulnar dislocation has been reported, but previous reports have not mentioned radial dislocation of the extensor tendon in the thumb. Radial dislocation of the extensor tendon of the thumb gradually progressed after cerebral hemorrhage and the patient could not extend MCP joint of the thumb. To resolve difficulty in extending the MCP joint, surgical centralization of the extensor tendon and partial resection of the flexor pollicis brevis (FPB) and abductor pollicis brevis (APB) insertions was performed. The patient recovered function of thumb extensors.

Abstract Introduction We review the benefits of early motion protocols following replantation of a total right hand amputation at 1 and 2 years after replantation, and provide recommendations for postoperative management. Materials and Methods Replantation of the entire right hand in zone-4 was performed and supported by rigid external fixation spanning the forearm and hand. An early active “place-and-hold” motion protocol was initiated within the first 3 postoperative days. Metacarpophalangeal joint extensors were tethered by the pins, limiting full excursion. This resulted in stiffness and extensor adhesions that required a staged extensor tenolysis; however, all joints remained supple. The early motion protocol prevented the need for significant flexor tenolysis and joint releases. Results Early motion rehabilitation protocols can produce very successful results in complex replantation. The enhanced stability afforded by external fixation of the wrist allowed us to perform aggressive early rehabilitation. Conclusion This case highlights the benefits of early active motion (limiting the need for complex joint and flexor tendon releases) and demonstrates the degree of extensor adhesions caused by even minor extensor tendon tethering. This aggressive rehabilitation approach can produce excellent range of motion, and likely limit the need for secondary tenolysis and joint release procedures.

Metacarpophalangeal Joints

After silicone arthroplasty of the metacarpophalangeal (MP) joint there is increasing osteolysis, subsidence and fracture of the implants in the longer postoperative term. In 44 patients with rheumatoid arthritis (54 hands) 151 arthroplasties of the metacarpophalangeal joint were assessed at a mean of 3.9 years postoperatively. In 57 arthroplasties titanium protectors (grommets) were used. There were no significant differences in the clinical outcomes with respect to swelling, correction of ulnar deviation, range of active movement and grip strength. The additional use of grommets in MP joint arthroplasty slightly reduced reactive osteolysis, protected the spacers from breakage and slightly reduced the amount of pain with only a few additional complications in the midterm follow-up.

A Taekwondo participant sustained a hand injury from punching an opponent that resulted in painful instability of the ring finger extensor digitorum communis tendon due to sagittal band damage. His symptoms resolved after reconstructive surgery on the sagittal band (SB) with stabilization of the extensor tendon over the metacarpophalangeal joint.

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.
