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:

Multiple finger flexor tendon pulley injuries, common in rock climbing, often require surgical intervention to prevent loss of function.
Traditional surgical techniques using bone-encircling grafts can lead to osteonecrosis (bone death) of the phalanx.
A novel transosseous technique is presented to address these limitations.

Purpose of the Study:

To describe and evaluate a new transosseous surgical technique for treating multiple finger flexor tendon pulley injuries.
To present a modification of the "loop and a half" technique that avoids the risk of osteonecrosis.

Main Methods:

The technique involves a standard palmar-sided incision, debridement, and creation of transosseous drill holes at the base phalanx.
A palmaris longus tendon graft is passed through the drill holes and interlaced.
The graft is then laced through the remaining pulley rims and flexor tendon sheath, secured, and followed by controlled mobilization.

Main Results:

No intraoperative or postoperative complications were reported.
Functional and sport-specific outcome scores were predominantly good to excellent.
No instances of osteonecrosis of the phalanx were observed post-surgery.

Conclusions:

The modified transosseous "loop and a half" technique is a safe and effective treatment for multiple finger flexor tendon pulley injuries.
This technique combines the benefits of existing methods while mitigating the risk of osteonecrosis.
It provides favorable functional recovery for patients with significant pulley ruptures.
