Attrition of the Extensor Tendon of the Index Finger Following an Avulsion Fracture of the Third Metacarpal

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.

Extensor Carpi Radialis

The extensor carpi radialis brevis (ECRB) muscle is an integral extensor and abductor of the wrist. It originates from the lateral epicondyle of the humerus, laying deep to the extensor carpi radialis longus and extensor digitorum communis, and superficial to the supinator. Insertion occurs at the base of the third metacarpal. The radial nerve or a derivative supplies innervation. Its significance in orthopedics is highlighted by its involvement in multiple surgical approaches, such as the Thompson and Kaplan approaches for exposure of the radius, as well as its association with several routinely observed pathologies. Many of the associated syndromes, such as lateral epicondylitis, arise from repetitive gripping motions or overuse and are frequently seen in the orthopedic clinic. This review seeks to provide a comprehensive summary of the relevance of the ECRB to the orthopedic setting to broaden knowledge of its anatomy and increase recognition and proper management of associated pathologies.

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.

Extensor Compartment

Accessory extensor tendons in the hand are not rare, usually asymptomatic, and recognized incidentally during elective surgery or cadaveric dissection. This report describes a novel case of symptomatic duplication of accessory extensor tendons to both the thumb and the index finger causing a painful dorsal wrist tenosynovitis. Excision of the accessory tendons with decompression and tenosynovectomy of the fourth extensor compartment alleviated the patient’s symptoms without compromising motion or function.

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.

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.
