4-anchor internal brace repair for perilunate dislocations

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

We will test if a 4-anchor internal brace repair leads to better healing and fewer complications than standard K-wire fixation in adults who have had surgical fixation for a perilunate dislocation.

What this trial studies

This observational study compares clinical and radiographic outcomes after perilunate dislocation repair using an internal brace 4-anchor construct versus the traditional Kirschner wire (K-wire) technique. Outcomes of interest include nonunion, reoperation, infection, fixation failure, and objective measures like range of motion, pain, numbness, and weakness. Researchers will collect complication incidence rates and compare functional and radiographic results between the two techniques. The study enrolls skeletally mature adults treated surgically for isolated perilunate dislocations and excludes patients with concomitant carpal fractures, prior ipsilateral perilunate dislocation, pediatric patients, and those aged 89 or older.

Who should consider this trial

Good fit: Adults aged 18–88 who are skeletally mature and have undergone surgical fixation for an isolated perilunate dislocation without concomitant carpal fractures or prior ipsilateral perilunate dislocation.

Not a fit: Pediatric patients, people aged 89 or older, patients with associated carpal fractures, or those with a prior perilunate dislocation on the same side are unlikely to benefit from or be eligible for this comparison.

Why it matters

Potential benefit: If the internal brace technique reduces fixation failures and complications, patients could have fewer reoperations and better wrist function after perilunate dislocation.

How similar studies have performed: Internal bracing has shown promising results in other ligament and wrist repairs, but direct comparative data versus K-wire fixation specifically for perilunate dislocations are limited, making this application relatively novel.
