Massive ankle fractures lead to joint stiffness and resulting decrease in range of motion. This can be avoided by functional treatment. In cases where severe soft tissue trauma coexists with bone fractures surgical treatment is limited and external fixation is the method of choice. Modern external fixation technique allows for stabilisation and maintaining range of motion in the affected joint. This paper presents the results of application of the Dynastab-S external fixator. The construction of this fixator allows dorsal and plantar, reducing postraumatic joint stiffness. It also allows appropriate insight into soft tissues and debridement of devitalised tissues as well as their forthcoming surgical reconstruction. In our material (27 cases) treated with the Dynastab-S fixator for an average of 16 weeks a satisfactory bone healing process in all cases was noted. Appropriate function of the extremity was maintained, with comparable plantar flexion to the contralateral, not affected joint. Only in one case post operative treatment was complicated by algodystrophy. Our observations showed that implementation of modern external stabilisation techniques leads to appropriate fracture healing with full function of the inferior extremity.
