Features of the macroscopic structure of the posterior inferior tibiofibular ligament based on anatomical study.

Objective: Aim: To study the anatomy of the posterior inferior tibiof i bular ligament (PITFL) and specify the features of its morphology and linear parameters.

Patients And Methods: Materials and Methods: The peculiarities of morphology and linear parameters of PITFL on 10 fresh amputated lower limbs were studied. The average age of the patients was 64.

BIOMECHANICAL COMPARISON OF THREE POSTERIOR MALLEOLUS FRACTURE FIXATION METHODS IN RELATION TO DIFFERENT FRACTURE MORPHOLOGY: A FINITE ELEMENT ANALYSIS.

The objective of this study was to compare the biomechanical behavior of three fixation methods for posterior malleolar fracture (PMF) in relation to different fracture morphology and to evaluate the corresponding changes of the stress distribution on the articular surface of the tibia plafond by finite element analysis (FEA). Three internal fixation techniques: two lag screws in antero-posterior direction (AP lag screws), two lag screws in postero-anterior direction (PA lag screws) and posterior plate (PP) were analyzed for posteromedial (PM) and posterolateral (PL) fragment of PMF using the FEA. The values of relative deformations, total displacements, and von Mises stress (VMS) in the model elements were estimated under vertical loading 700 N.

OSTEOCHONDRAL AUTOLOGOUS TRANSPLANTATION VERSUS ARTHROSCOPIC DEBRIDEMENT WITH DRILLING IN THE TREATMENT OF TALAR OSTEOCHONDRAL LESIONS AND DEFECTS.

Objective: The aim: To conduct a comparative analysis of the results of arthroscopic debridement with drilling (ADD) versus osteochondral autologous transplantation (OAT) in the treatment of talar osteochondral lesions and defects (OHLD) based on the assessment of the function of the ankle joint, the level of pain and changes in the range of movements (ROM) in the affected joint.

Patients And Methods: Materials and methods: The study included 40 patients with OHLD, with an average area of 3.14 cm2 and a depth of 1.

[Predictors of a knee-joint preserving during high amputation of the lower extremity in a purulent-necrotic complications of obliterating angiopathy].

The causes, influencing possibility of a knee joint preservation, when performing tne lower extremity high amputation, were analyzed in 65 patients while occurrence of purulent-necrotic complications of obliterating angiopathy. In accordance to results of logistic regression the value of comorbidity index 4 and more have appeared significant as a predictor of impossibility to preserve a knee joint. In its bigger or lesser values a success or failure of transtibial amputation is possible.

[Transtibial amputation of the lower extremity in patients with ischemic foot contracture].

The results of operative treatment of 8 patients was analyzed, in whom the lower extremity amputation on the upper third of the shin was performed for severe stage of the ischemic foot contacture. Operative interventions is expedient to perform in a specialized stationary, were exists possibility of further prosthesis. It is necessary to perform the extremity amputation in a residual period of the foot ischemic contracture, when operations for restoration of the sole sensitivity are nonperspective as well as in presence of severe trophic disorders on the sole and the shin, but without purulent--necrotic signs.
