[Dorsal ligamentoplasty for posttraumatic scapholunate dissociation].

This study aimed to evaluate a modified dorsal ligamentoplasty in second- and third-degree scapholunate dissociation in a prospective study design. Furthermore, the study aimed to find out if there is a correlation between radiological and clinical parameters at follow-up and whether or not a SLAC wrist can be avoided. From 2007 to 2011 we performed 29 dorsal ligamentoplasties in our hospital in patients with second- and third-degree scapholunate dissociation. In a prospective study design, 25 patients were followed up after an average period of 18 months. Parameters recorded preoperatively included ROM, the radiological parameters SL diastasis, SL diastasis in power grip and SL angle, the DASH score, and the VAS score. The postoperative evaluation additionally included power grip, the Mayo wrist score, and patients' subjective satisfaction. The average subjective satisfaction after surgery was good. The average postoperative ROM was 83.8 % of the ROM of the healthy wrist and decreased by 11 % compared with the preoperative level. The average postoperative grip strength was 85.7 % of the strength of the healthy hand. The VAS score was 2.7 with a significant reduction from 6.7 preoperatively. The average DASH score decreased significantly from 60 preoperatively to 22.5 postoperatively. The average Mayo wrist score after surgery was 73. All radiological parameters at follow-up were significantly better than preoperatively, although they remained in a pathological range. T...
