Objectives: We aimed to evaluate the results of arthroscopic dorsal capsuloligamentous repair in the treatment of cases with floating lunatum (FL) (presence of both scapholunate interosseous ligament (SLIL) and lunotriquetral interosseous ligament (LTIL) instability).
Methods: Twelve patients (5 female, 7 male) (mean age: 36.6 years) who were operated on for FL between 2009 and 2014 were evaluated retrospectively. Accompanying wrist pathologies were investigated by radiocarpal and midkarpal joint arthroscopy. The patients whom both scapholunate (SL) and lunotriquetral (LT) joint instabilities were detected arthroscopically were treated with capsular debridement and dorsal ligamentocapsulodesis repair for both SL and LT joints. Preoperative and postoperative VAS (visual analog scale) values, Mayo wrist scores, grip strength and joint range of motion were evaluated in all patients.
Results: At the end of mean 32 (range: 24-52) months follow-up period, none of the patients had recurrence. The preoperative VAS score was 6.4 (range: 4-8) and the postoperative average was 1.2 (range: 0-3). According to the Mayo wrist scoring, excellent results were obtained in 22 patients and good result was obtained in 1 patient.
Summary points: The patients with FL injuries have become more detectable after arthroscopic evaluation. FL is not always seen as a secondary to trauma, and radiological findings do not always support recognition. Midcarpal arthroscopic examination should be performed in patients with chronic wrist pain. We think that the treatment results of dorsal ligamentocapsulodesis operation for both LT and SL joints are satisfactory.
