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

All patients, 18 years of age and older, who undergo operative fixation for perilunate dislocations without fracture at the level one trauma center, Orlando Health Orlando Regional Medical Center.
