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.

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.

We report an avulsion fracture at the base of the third metacarpal involving the extensor carpi radialis brevis insertion and a resulting complication of attritional rupture of the extensor indicis proprius tendon and the extensor digitorum communis to the index finger, in a 67-year-old man.

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.

Arthroplasty Procedure

Replacing a destroyed MCPJ has always been a challenge. Few operations have resulted in consistent satisfactory results. Also, anchoring a subluxed EDC tendon from the metacarpal head has produced numerous corrective procedures, again indicating the difficulty to keep the extensor tendon aligned. The EDC anchor and interposition arthroplasty procedure addresses both these challenging problems.

Extensor Carpi Radialis

The relative contributions of the forearm extensors to the tensile force at the lateral epicondyle were examined by implanting a force transducer in the common extensor tendon of four soft fixed cadaver elbows and sequentially stretching each muscle arising from the lateral epicondye. Extensor carpi radialis brevis and extensor digitorum communis produced the largest increases while the superficial head of supinator produced a moderate increase in tensile force in the common extensor tendon. Extensor carpi radialis longus and extensor carpi ulnaris had no significant effect. Radial tunnel pressure was measured using a balloon catheter in a separate study of five cadaver elbows. Radial tunnel pressure increased on moving the wrist from neutral to a flexion–pronation position. This positional rise in pressure was reduced by supinator musculotendinous lengthening (77%) while lengthening of the extensor carpi radialis brevis and extensor digitorum communis had no effect. This study demonstrates a biomechanical basis for the superficial head of supinator in the aetiology of both lateral epicondylitis and radial tunnel syndrome.
