A 4-Anchor Construct With Internal Bracing Technique for Surgical Treatment of Perilunate Dislocations

A 4-Anchor Construct With Internal Bracing Technique for Surgical Treatment of Perilunate Dislocations: A Prospective Study

The purpose of the research study is to determine the overall clinical and radiographic outcome differences between internal brace technique and the gold standard Kirschner wires (K-wire) technique for treatment of perilunate dislocations (e.g. nonunion, reoperation, infection, fixation failure, etc.). A secondary purpose is to determine the specific types of complications and their incidence rates with respect to internal brace technique and the gold standard Kirschner wires (K-wire) technique (e.g. range of motion losses, pain, numbness, weakness, etc).

Inclusion Criteria:

• Skeletally mature patients who have undergone surgical fixation of perilunate dislocation

Exclusion Criteria:

• Perilunate dislocations with concomitant carpal fracture(s)
• Pediatric patients (Age < 18 years-old)
• Patients whose age is greater than or equal to 89 years
• History of previous perilunate dislocation on ipsilateral side
