Muscles of the Forearm that Move the Hand and Fingers

Muscles of the Forearm that Move the Hand and Fingers

The muscles of the forearm that move the wrist, hand, and digits are numerous and diverse. They can be classified into two groups based on their location and function — the anterior and posterior compartment muscles.
Anterior Compartment
The anterior compartment muscles originate from the humerus. They primarily function as flexors and are also known as flexor muscles. They typically insert on the carpals, metacarpals, and phalanges. The superficial layer includes the flexor carpi...

Area of Science:

Orthopedic Surgery
Sports Medicine
Hand Surgery

Background:

Extensor carpi ulnaris (ECU) subsheath injuries are increasingly recognized causes of ulnar-sided wrist pain in elite athletes.
There is limited surgical outcome data specific to elite athletes with these injuries.

Purpose of the Study:

To evaluate the surgical outcomes of ECU subsheath reconstruction in elite athletes.
To analyze specific considerations for managing these injuries in a high-performance population.

Main Methods:

Retrospective review of 14 elite athletes undergoing ECU subsheath reconstruction.
Analysis of clinical, MRI, and intraoperative findings.
Subgroup analyses for hockey players and acute injuries.

Main Results:

Mean postoperative pain was 0.25 (VAS).
Excellent recovery in grip strength (P=.001) and wrist motion (P=.037).
Mean return to sport was 92.5 days with no complications.

Conclusions:

Surgical management of ECU subsheath injuries is effective in elite athletes.
The procedure is viable for both acute and chronic injuries.
Surgical intervention may be superior to nonoperative management for this population.
