Summary

Posterior peri-lunate wrist dislocations often result in functional impairment and pain. Scapho-lunate ligament repair may improve healing and reduce carpal instability risks.

Area of Science:

  • Orthopedic Surgery
  • Traumatology
  • Hand Surgery

Background:

  • Posterior peri-lunate dislocations are complex wrist injuries.
  • Understanding prognostic factors is crucial for patient outcomes.

Purpose of the Study:

  • To report experience with 25 posterior peri-lunate wrist dislocations.
  • To identify prognostic factors by comparing outcomes with literature data.

Main Methods:

  • Retrospective review of 25 patients (24 male, 1 female; mean age 36).
  • Classification into pure (n=16) and trans-scapho-lunate (n=9) dislocations.
  • Analysis of treatment variations (open/closed, pinning, ligament suture, screw fixation) and outcomes over a mean 57-month follow-up.

Main Results:

Related Experiment Videos

  • 22 patients reported residual pain; 21 had subjectively good/very good outcomes.
  • Significant functional deficits noted: 8 patients with impaired wrist movement, 20% force reduction.
  • Poor functional/radiographic results correlated with carpal instability; wrist stiffness was also a concern.

Conclusions:

  • Functional impairment is common after posterior peri-lunate dislocation.
  • Treatment type showed no statistical correlation with outcome in this small series.
  • Scapho-lunate ligament repair may be beneficial for healing and reducing instability.
