Fractures: Bone Repair

3.2K
Treatment for a fracture is based on the type of break, the bone affected, and the patient's age.
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the...

Summary

Restoring finger extension after severe forearm injuries can be achieved using the biceps and triceps muscles. These muscles serve as effective alternative donors when conventional options are unavailable, significantly improving hand function.

Area of Science:

  • Orthopedic Surgery
  • Reconstructive Surgery
  • Hand Surgery

Background:

  • Restoring finger extension is vital for hand function after severe injuries.
  • Mangled forearm injuries often damage conventional donor sites for tendon transfers.

Purpose of the Study:

  • To evaluate the efficacy of biceps and long head of triceps transfers for finger extension restoration.
  • To detail treatment considerations, surgical techniques, and outcomes for these transfers.

Main Methods:

  • Two patients with sequelae of mangled forearm injuries underwent tendon transfers.
  • Biceps and long head of triceps were transferred to the finger extensors.

Main Results:

  • Both patients demonstrated dramatic improvement in hand function.
  • Patients reported high satisfaction with the restored finger extension and overall hand use.

Conclusions:

  • Biceps and long head of triceps are viable second-line donor options for finger extensor reconstruction.
  • These transfers offer a valuable solution when conventional donors are compromised by extensive forearm trauma.
