Arthroscopic reductions successful in treatment of perilunate and fracture dislocations

Researchers found arthroscopic reduction with percutaneous fixation to be a reliable minimally invasive surgical method for acute perilunate injuries, according to a study published in Arthroscopy.
A team from Dankook University College of Medicine in Seoul studied 20 patients with a perilunate dislocation or a fracture-dislocation who were treated with arthroscopic reduction and percutaneous fixation at a median interval of 3.9 days from the time of injury between April 2002 and November 2008. The study included 19 men and 1 woman with a mean age of 37.3 years.
According to the study, the participants were retrospectively studied at a mean follow-up of 31.2 months with range of motion and grip strength being assessed. Functional outcomes were determined radiographically, along with the modified Mayo wrist score; Disabilities of the Arm, Shoulder and Hand questionnaire and Patient-Rated Wrist Evaluation score.
The researchers found that the flexion-extension motion arc and grip strength of the injured wrist averaged 79% and 78%, respectively, of the corresponding values for the contralateral wrists, according to the study results. The mean Disabilities of Arm, Shoulder and Hand score was 18, and the mean Patient-Rated Wrist Evaluation score was 30. According to the Mayo wrist scores, overall functional outcomes were rated as excellent in three patients, good in eight, fair in seven and poor in two.
“This study suggests that arthroscopic reduction with percutaneous fixation is a reliable minimally invasive surgical method for acute perilunate injuries in that it provides proper restoration and stable fixation of carpal alignment and results in satisfactory functional and radiologic outcomes on a midterm basis,” the authors wrote in the abstract.
