[Physiolysis with Resection of Vickers' Ligament in Adolescent Patients with Madelung's Deformity].

BACKGROUND

Madelung's deformity is a congenital or acquired growth disorder of the forearm that can lead to significant impairments in the quality of life of affected patients. Various surgical treatment options for the condition have been described in the literature. This study aimed to investigate whether physiolysis with resection of the Vickers ligament can successfully halt the progression of the disease in a cohort of young patients, as would be expected based on existing literature on this topic.

MATERIAL AND METHODS

An analysis was performed on the records of all patients with Madelung's deformity who were primarily treated with physiolysis with resection of the Vickers ligament between January 2001 and June 2017. Patients were invited for follow-up examinations, and surgical outcome was assessed. Parameters evaluated included pain at rest and under load, range of motion of the wrists, and activity level. Additionally, standard X-rays and radiological measurements were performed for each operated wrist. The collected data was compared with the preoperative data from patient records.

RESULTS

Nine wrists were included in the study. The average age at the time of surgery was 13.2 years, and the average follow-up period was five years. Extension and ulnar abduction showed a slight decrease from preoperative to follow-up, while flexion improved minimally, and radial abduction and forearm rotation showed noticeable improvement. The visual analogue scale score for pain at rest increased from preoperative 0.25 points to 1.88 points at follow-up. Under load, the average pain score increased from 2.00 to 4.25 points. The mean DASH score increased from 6.04 points before the surgical procedure to 12.20 points at follow-up. The average values of two out of the five measured McCarroll parameters increased, the increase being statistically significant for lunate subsidence. A follow-up procedure was required in one wrist.

CONCLUSION

In our cohort, the progression of Madelung's deformity was only partially halted by physiolysis with resection of the Vickers ligament, and a significant increase in pain symptoms during the study period could not be avoided. Therefore, this procedure should be used cautiously in skeletally immature patients.
