Influence of surgical performance on clinical outcome after osteosynthesis of distal radius fracture.

Clinical outcome after surgery depends on the surgeon's level of expertise or performance. The present study of minimally invasive plate osteosynthesis (MIPO) with anterior plate for distal radius fracture assessed whether clinical outcome correlated with surgeon performance. The series included 30 distal radius fractures: 15 operated on by 4 level III surgeons (Group 1) and 15 by 4 level V surgeons (Group 2), utilizing the MIPO technique. The surgical performance of all 8 surgeons was assessed using the OSATS global rating scale. Clinical outcomes were assessed at 3 months' follow-up using the modified Mayo score (MMS), in 4 grades: 0-64 (poor), 65-79 (moderate), 80-89 (good), and 90-100 (excellent). The QuickDASH score (QDASH) was also calculated, and complications were recorded. Median MMS was better for level V (75 = fair result) than level III surgeons (62 = poor result). Median QDASH score likewise was better in group 2 (9.1) than group 1 (22.7). In group 1, there were 2 paresthesias in the median nerve territory, 1 type-1 complex regional pain syndrome, and 1 hypoesthesia in the scar area. Mean correlation between the 2 scores was -0.68. Group 1 patients were on average 7 years older. The number of patients, number of surgeons and distribution of OA A and C fractures were almost identical in the two groups. On MMS, the overall result of the two groups was moderate (70.5), which can be explained by short mean follow-up. Quality of the clinical outcome on MMS and QDASH increased with surgical performance, with fewer complications. In the patients' interest, protocols for improving surgical performance should be implemented, for example, through deliberate practice.
