Summary

Arthroscopic release of the SCM muscles with radiofrequency under local anesthesia is an effective method for the treatment of CMT with low risk of neurovascular injury and satisfactory cosmetic results.

Abstract

Background

Congenital muscular torticollis (CMT) is considerated to be the third most common congenital musculoskeletal anomaly. Questions remain as to the efficacy of arthroscopic surgical treatment for CMT. The aim of this retrospective cohort study was to determine whether the efficacy of release of the sternocleidomastoid (SCM) muscle arthroscopically is better than open surgery for the treatment of CMT.

Methods

From April 2008 to May 2016, a total of 49 patients (24 men and 25 women) were surgically treated for CMT in the Chinese PLA Genneral Hospital. According to the different methods of operation, the patients was divided into two groups. In the arthroscopic surgery group, 28 patients (13 men and 15 women) with a mean age of 18.5 years were surgically treated with arthroscopy under local anesthesia. The sternal and clavicular attachments were dissected with radiofrequency. In the open surgery group, 21 patients (11 men and 10 women) with a mean age of 17.2 years were treated with conventional surgery under general anesthesia. Both groups were clinically assessed using a modified Cheng and Tang score.

Results

Baseline conditions of the two patient groups were comparable. All patients were successfully surgically treated and followed up for more than 24 months. No recurrence or serious complications were observed at the final follow up. According to the modified Cheng and Tang scale, 11 patients showed an excellent result and 10 patients had a good result in the open surgery group group. However, in the arthroscopic surgery group, 21 patients showed an excellent result and 7 patients had a good result. The excellent rates between two groups were significant different (P<0.05).

Conclusions

Arthroscopic release of the SCM muscles with radiofrequency under local anesthesia is an effective method for the treatment of CMT with low risk of neurovascular injury and satisfactory cosmetic results.
