Abstract:
Objective:To analyze the causes of equinus deformity caused by intramuscular venous malformation onset posterior muscles of leg, and discuss the corresponding treatment methods.
Methods:A retrospective study was conducted on 69 cases of intramuscular venous malformations with equinus deformity from January 2012 to December 2017. Based on patient's main complain, physical examination and imaging data, the causes were divided into two categories: pain disorder and contracture disorder. Classification was on the basis of definite diagnosis of MRI. When the main complaint of medical history and physical examination indicated pain relief or passivity of the affected limb, and when the back extension of ankle joint was greater than 75 degrees, it was a pain disorder; when the medical history and physical examination indicated pain relief or passivity of the affected limb, the back extension of ankle joint was less than 15 degrees, it was a contracture disorder. Therapeutic methods included drug conservative treatment and surgical treatment. For the patients with pain disorder, the first choice was drug conservative treatment, and for the patients with contracture disorder, the first choice was surgery. Operative methods include simple venous malformation resection, venous malformation resection and Z-type Achilles tendon anastomosis lengthening. After operation patients received systematic functional rehabilitation exercise and calculated the satisfaction rate.
Results:13 cases of painful disorders were firstly treated by conservative medicine, but 4 cases were treated by operation after series of conservative treatments, satisfaction rate was 69.2%(9/13). 56 contracture cases were treated by operation, including 11 cases of simple venous malformation resection, 45 cases resection and Z-type anastomosis lengthening of Achilles tendon. All the patients were followed up for 6 months to 2 years after operation. 53 patients recovered to normal walking after operation, and 3 patients had mild limp, satisfaction rate was 94.6%(53/56). Patient satisfaction was 100%.
Conclusions:The equinus deformity caused by intramuscular venous malformation onset posterior muscles of leg affect the quality of life. Muscle/tendon contracture was the main cause. Correct surgical treatment combined with early rehabilitation exercise post operation can restore normal walking posture.
