Is the use of neuromonitoring necessary in Sprengel's deformity surgery?

Abstract

This study aimed to emphasize the effectiveness of using intraoperative neuromonitoring (IONM) in preventing possible nerve damage in Sprengel's deformity surgery. Eighteen patients who underwent Woodward surgery accompanied by neuromonitoring due to Sprengel's deformity were included in the study. Demographic information of the patients and their clinical and cosmetic results before and after surgery were recorded. Complications that occurred during and after the surgery were recorded. Of the 18 patients who underwent surgery, 12 were female and 6 were male. The mean age of the patients was 4.4 (2-8). The mean shoulder abduction angle of the patients was 84.4 (65-105) degrees before the surgery and 151.1 (125-175) degrees in the first year after the surgery. The mean Cavendish score of the patients was 3.6 (3-4) before the surgery and 1.1 (1-2) in the first year after the surgery. In one patient, there was a decrease in IONM motor-evoked potency signals during the reduction of the intraoperative scapula. Considering some loss of correction in the deformity, the scapula was detected at the point where there was no loss of signals. No patients developed wound problems or infections. In this study, it was determined that the use of neuromonitoring was effective in preventing brachial plexus damage, even if this complication was minimal in patients operated on due to Sprengel's deformity.
