Achieving excellent reduction in Bennett's fractures is crucial for long-term outcomes. Poor reduction quality correlates with increased arthritis and persistent symptoms, impacting patient function.

Area of Science:

  • Orthopedic Surgery
  • Traumatology
  • Radiology

Background:

  • Bennett's fractures are common injuries affecting the thumb carpometacarpal joint.
  • The quality of fracture reduction significantly influences long-term joint health and patient-reported outcomes.
  • Residual displacement after treatment can lead to degenerative changes and functional limitations.

Purpose of the Study:

  • To investigate the correlation between the quality of reduction in Bennett's fractures and the subsequent development of arthritic changes, symptoms, and disability.
  • To evaluate the long-term functional and radiographic outcomes based on initial fracture reduction quality.

Main Methods:

  • A retrospective study of 41 patients with Bennett's fractures.
  • Fractures were treated using closed reduction with plaster immobilization, percutaneous K-wire fixation, or open reduction.

  • Outcomes assessed included radiographic position, patient-reported symptoms, disability, and radiographic signs of arthritis after a median follow-up of 7.3 years.

    • Main Results:

    • Excellent reduction was achieved in 5/9 (closed reduction), 4/6 (K-wire fixation), and 18/26 (open reduction) fractures.
    • 15/18 patients with excellent reduction were symptom-free at follow-up, compared to 6/13 with residual displacement.
    • Radiographic arthritis was present in 3/14 patients with excellent reduction versus 7/10 with residual displacement.

    Conclusions:

    • High-quality reduction in Bennett's fractures is associated with better long-term symptom relief and reduced risk of arthritis.
    • Residual displacement after treatment for Bennett's fractures is linked to a higher incidence of arthritis and persistent symptoms.
    • Open reduction techniques appear to offer a higher rate of achieving excellent fracture reduction.
