Muscles of the Forearm that Move the Hand and Fingers01:16

Muscles of the Forearm that Move the Hand and Fingers

3.4K
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...

Summary

Severe finger injuries with extensor tendon loss can be challenging. A salvage technique involves transplanting a tendon from an unsalvageable finger to reconstruct large extensor tendon gaps in zone I.

Area of Science:

  • Orthopedic surgery
  • Hand surgery
  • Trauma surgery

Background:

  • Acute extensor tendon injuries, including laceration, crush, and avulsion, are common.
  • Severe injuries can result in significant tendon loss and gaps, particularly in extensor zone I.
  • Reconstruction of these defects presents a significant surgical challenge.

Observation:

  • This article presents a salvage technique for reconstructing large extensor tendon gaps in extensor zone I.
  • The technique involves transplanting a tendon from an unsalvageable finger to repair a terminal tendon gap in another finger of the same patient.
  • This method is designed for patients with severe, multi-finger injuries.

Findings:

  • The described tendon transplantation technique offers a salvage option for significant extensor tendon loss.
  • It may be a reasonable remedy for reconstructing large extensor tendon gaps.
  • This approach can provide advantages over traditional reconstructive methods in specific clinical scenarios.

Implications:

  • This salvage technique expands reconstructive options for severe extensor tendon injuries.
  • It offers a potential solution for complex cases where traditional methods may be insufficient.
  • Further evaluation may confirm the advantages of this approach in improving functional outcomes for patients with multi-finger extensor tendon loss.
