Radial hand crush injuries can severely impact thumb function. Mild cases heal well, but bone and joint damage leads to poor outcomes, though some surgical interventions can improve thumb function.

Area of Science:

  • Orthopedic Surgery
  • Hand Surgery
  • Traumatology

Background:

  • Crush injuries to the radial side of the hand present a diverse range of severity.
  • Thumb function is a primary concern following such trauma.
  • A significant spectrum of injuries, from muscle contusions to complete tissue loss, can occur.

Purpose of the Study:

  • To review the outcomes of radial hand crush injuries.
  • To identify factors influencing functional recovery, particularly of the thumb.
  • To evaluate the effectiveness of different treatment modalities, including surgical interventions.

Main Methods:

  • Retrospective review of 161 cases of radial hand crush injuries.
  • Analysis of treatment strategies including conservative management, debridement, skin flaps, and opponensplasty.

  • Correlation of injury severity and treatment with functional outcomes.

    • Main Results:

    • Mild injuries treated conservatively or with debridement showed good results.
    • Cases requiring skin flaps for coverage also yielded satisfactory outcomes.
    • Injuries involving bone and joint damage resulted in poor functional outcomes.
    • Opponensplasty was effective in improving thumb function in select patients with scarred tissue.

    Conclusions:

    • Conservative treatment and debridement are effective for mild radial hand crush injuries.
    • Surgical reconstruction, including skin flaps, can achieve satisfactory results.
    • Severe injuries with bone and joint involvement have poor prognoses.
    • Opponensplasty is a viable option for functional thumb restoration in specific complex cases.
