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.

Extensor Digitorum Communis

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.

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.

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.

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.

Finger Motion

We present a case of a gradually developing ischaemic contracture of the forearm muscles of an infant who developed without any trauma or acute gangrene at birth. Release of the middle and ring finger digitorum profundus muscles and pronator quadratus at 2 years of age corrected the deformity. Histopathology showed no evidence of fibromatosis or any other tumor. Although a dynamic splint was used to maintain the range of motion, the range of the middle finger motion deteriorated gradually 2 years after surgery. Though the pathogenesis of this problem was unclear, we assume that it was caused by fibrosis of muscles as a result of bleeding before or during delivery.

Extensor Lag

Subluxation of the extensor digitorum communis tendons in the rheumatoid hand causes ulnar digital drift. If passively correctable, the digit may be realigned by soft tissue rebalancing and extensor centralization, which may preserve a more functional arc of motion than achieved with arthroplasty. A total of 71 centralization procedures were done in 15 rheumatoid patients with a mean age of 55 years and an average follow-up of 9 years. A distally based central-third strip of extensor tendon was used. Correction of ulnar drift deformity was from an average of 47° preoperatively to 7.9° postoperatively, and correction of active range of motion of the metacarpophalangeal joints was from an average of 38° to 56.2°. Reoperation and complication rates were low. This technique corrects and maintains ulnar drift in the rheumatoid hand. Range of motion at the metacarpophalangeal joint level is improved and converted to a more functional one by decreasing the extensor lag.

Flexor Digitorum

This study reports on outcomes of the flexor digitorum superficialis tendon transfer from the ring finger in Type II and IIIA hypoplastic thumbs. We included 22 patients with 27 involved hands: 16 Type II thumbs and five Type IIIA treated by transfer and six non-operated Type II thumbs. The outcomes were assessed by range of motion, strength, sensibility, joint stability and patient/parent satisfaction. Compared with normative data, the range of motion was diminished in all patient groups. Opposition strength in operated Type II thumbs was significantly better than in non-operated thumbs. Grip strength, pinch strength, tripod strength and key pinch strength were approximately 50% of normal in Type II thumbs and 35% in Type IIIA thumbs. Metacarpophalangeal joint stability was restored in all operated Type II thumbs and in 40% of Type IIIA thumbs. We conclude that the flexor digitorum superficialis tendon transfer of the ring finger is a good functioning opponensplasty in both Type II and IIIA thumbs. The transfer provides excellent stability of the metacarpophalangeal joint in Type II thumbs. Level of Evidence: Level IV
