Forces required to dynamize sliding screws in gamma nail and selfdynamizable internal fixator.

Background: Single limb support phase of the gait-cycle in patients who are treated for a pertrochanteric fracture is characterized by transversal loads acting on the lag screw, tending to block its dynamization. If the simultaneous axial force overcomes transversal loads of the sliding screw, the dynamization can still occur.

Methods: Biomechanical investigation was performed for three types of dynamic implants: Gamma Nail, and two types of Selfdynamizable Internal Fixators (SIF) - SIF-7 (containing two 7 mm non-cannulated sliding screws), and SIF-10 (containing one 10 mm cannulated sliding screw).

Does ligamentotaxis reduce the risk of avascular necrosis of the talus after lateral subtalar dislocation.

Lateral subtalar dislocations are rare and severe injuries caused by high-energy trauma, and they require urgent treatment. We reported two cases of lateral subtalar dislocation, which were treated with different methods. In case of open lateral subtalar dislocation, we used the method of distractional external fixation; the final outcome was good, without avascular necrosis of the talus.

[The role of capsuloligamentotaxis and minimally invasive percutaneous osteosynthesis with rigid and dynamic unilateral external fixation of the intra-articular pilon fracture].

Fractures of the tibial pilon are severe injuries which can be accompanied by articular impaction, comminution and soft tissue injury. Soft tissue injury with already existing skin damage can further complicate the method of treatment. In these cases, the method of unilateral or circular external fixation can be used as an alternative method of treatment.

Lateral tibial plateau fractures-functional outcomes and complications after open reduction and internal fixation.

Purpose: Tibial plateau fractures are severe intra-articular injuries; their treatment is accompanied by numerous complications and requires extensive surgical experience. In this manuscript, we compared our experiences with data from the literature.

Methods: Retrospectively, we analyzed 41 patients with closed lateral tibial plateau fracture (Schatzker's I-III).
