Extensor Digitorum Brevis Manus - Report of a Case and Treatment Planning

LT Glickman, BW Brewer. Extensor digitorum brevis manus – Report of a case and treatment planning. Can J Plast Surg 1994;2(2):95-96. The extensor digitorum brevis manus muscle (edbm) is an anomalous extrinsic extensor that may occur in up to 3% of the population and may produce symptoms and signs that are very similar to those of a dorsal ganglion. We report a case of edbm in a male whose diagnosis was made intraoperatively. He remains symptom free following surgical resection.

Painful extensor digitorum brevis manus muscle

Diagnosis was confirmed of 10 extensor digitorum brevis manus muscles in 7 patients. The muscle is located on the dorsum of the hand, just distal to the wrist. It is most prominent with the wrist flexed to 30 degrees and the fingers fully extended. We propose that pain in the extensor digitorum brevis manus muscle is due to compression of the muscle in the rigid fibro-osseous fourth dorsal compartment. Extensor retinacular release is the treatment of choice.

Anatomic and clinical studies of the extensor digitorum brevis manus

The extensor digitorum brevis manus muscle (EDBM) was found in 17 (3.0%) out of 559 dissected hands of 286 cadavers. The anatomy of the EDBM was classified into three types. The EDBM frequently arose on the distal margin of the radius, but without direct attachment to the carpal bones. The insertion of the EDBM was the same as that of the extensor indicis proprius. The EDBM and the extensor indicis proprius were often joined and had the same nerve and arterial supply. The EDBM muscle was considered to be a variant of the extensor indicis proprius muscle. Clinically five of 29 patients with an EDBM were treated.

Extensor digitorum brevis manus: A case report and review

A detailed description of bilateral extensor digitorum brevis manus (EDBM) present in a female cadaver is presented. The need for clinical recognition is emphasized. Prevalence, morphological variability and theories of ontogeny are reviewed. Clinical significance and possible function are discussed. Since misdiagnosis may result from the anatomical variability and lack of clinical awareness, the need for further study is emphasized.

Synovitis of the Extensors of the Fingers Associated with Extensor Digitorum Brevis Manus Muscle A Case Report

The extensor digitorum brevis manus muscle, an uncommon anomaly that has been described by many anatomists, was also considered by LeDouble in his monograph published in 1897. The prevalence of this muscle varies greatly, depending upon the report reviewed. It arises from the metacarpal bases or from the carpal bones, usually in the region of the scaphoid or lunate, and inserts into the tendons of the extensor digitorum communis near the metacarpophalangeal joints. Its area of insertion is variable, usually near the metacarpophalangeal joint of the index, middle and ring fingers or any combination of these.2 When its presence is unknown, it may suggest a dorsal ganglion of the hand or wrist, possibly a hematoma after injury, or some other tumor of the dorsum of the hand.1 The muscle probably represents a homolog of the extensor digitorum brevis of the foot.

Extensor digitorum brevis manus

Two patients with symptoms caused by an extensor digitorum brevis manus muscle are described. The literature is discussed. Excision of the abnormal muscle belly would appear to be the most certain method of obtaining complete relief.
