Study: NCT01785264

Intervention type: PROCEDURE
Group type: ACTIVE_COMPARATOR
Intervention: Non-operative treatment
Description: All patients included in the study will be immobilized in equinus position for the first two weeks using a below-the-knee cast. Following the first two weeks the cast is replaced with a brace that will be used for additional six weeks during which the ankle angle will be adjusted from 3 heel-lifts to none. Patients randomized to non-operative treatment will have a cast applied within 3 days from injury.

Intervention: Mini-invasive surgery
Description: We will use the technique developed by Dr. Amlang and Professor Zwipp from Dresden, Germany. They have developed a protocol of mini-invasive surgery using specially adapted proprietary instruments.~All patients included in the study will be immobilized in equinus position for the first two weeks using a below-the-knee cast. Following the first two weeks the cast is replaced with a brace that will be used for additional six weeks during which the ankle angle will be adjusted from 3 heel-lifts to none.
