Fractures: Bone Repair

2.9K
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...

Area of Science:

  • Orthopedic Surgery
  • Trauma Surgery
  • Hand Surgery

Background:

  • Metacarpal fractures are common hand injuries.
  • Intramedullary fixation (IMF) is an established treatment option.
  • Limited prospective data exists on IMF outcomes for metacarpal fractures.

Purpose of the Study:

  • To assess the outcomes of metacarpal fractures treated with IMF.
  • Evaluate patient-reported outcomes, grip strength, and total active motion.
  • Determine the complication rate associated with IMF for metacarpal fractures.

Main Methods:

  • Prospective multicenter trial of closed, extra-articular metacarpal fractures treated with IMF.
  • Radiographic healing assessed postoperatively.
  • Patient-reported outcomes (pain, QuickDASH, SF-36), grip strength, and motion measured.

Main Results:

  • 101 fractures in 82 patients showed significant QuickDASH score improvement (40 points).
  • Final grip strength averaged 15 kg, total active motion 228°.
  • Low complication rate (3.9%) with 3 revisions required.

Conclusions:

  • Intramedullary fixation is a reliable technique for extra-articular metacarpal fractures.
  • Satisfactory patient outcomes, excellent strength, and motion were observed.
  • IMF is a viable option for closed, extra-articular metacarpal fractures.
