AbstractBackground:Hip joint replacement (endoprosthesis, alloplasty) has become one of the most frequent surgery interventions of the 20th century.Aim:To conduct rehabilitation therapy in the late post-surgery period of hospital rehabilitation (45 days after surgery), to track patients’ progress and measure the results.Materials and methods:One hundred and fifty-two patients with hip joint endoprosthesis were included in the study. All underwent surgery and rehabilitation at the Department of Clinical Rehabilitation of the Physical and Rehabilitation Medicine Clinic at Doctor G. Stranski University Hospital, Pleven. Kinesitherapy included therapeutic massage, isometric exercises for gluteal and hip muscles, isotonic exercises for the hip and the knee joint, breathing exercises, analytical gymnastics, exercises for balance and posture stability; gait control, exercises with gym equipment; occupational exercises included all activities of daily living (ADL) that were practiced at home; treatment with performed physical factors included applying magnetic field, interferential current therapy, electrostimulation of them. quadriceps femorisand the gluteal muscles.Results:The scores from the pain visual analog scale (VAS), the muscle strength test and the test for the movement volume of the hip joint were obtained at the beginning and at the end of the rehabilitation process and stored in an individual file for each patient.Conclusion: The results of the present study suggest that the complex rehabilitation program (kinesitherapy, performed physical factors and occupational therapy) can result in a considerably faster recovery and ensures that patients reach optimal functional results.

AbstractEndoprosthesis stem fractures are among the rarest complications that occur after hip joint arthroplasty. The aim of this paper is to evaluate the causes of the fractures of the Aura II stem neck, which is an element of an endoprosthesis implanted in a patient. In order to achieve it, a radiogram was evaluated, the FEM analysis was carried out for the hip joint replaced using the Aura II prosthesis and scanning tests as well as a chemical analysis were performed for the focus of fatigue. The tests performed indicate that the most probable causes leading to the fatigue fracture of the Aura II stem under examination were material defects in the process of casting and forging (forging the material with delamination and the presence of brittle oxides and carbides) that resulted in a significant reduction of strength and resistance to corrosion. In the light of an unprecedented stem neck fracture, this information should be an indication for non-destructive tests of ready-made stems aiming to discover the material and technological defects that may arise in the process of casting and drop forging.

The paper presents a complex study on hip joint endoprosthesis. The model for the femur was obtained by CT scanner and Mimics, the endoprosthesis was designed in proEngineer. This study has two stages: obtaining the 3D model for the bone and endoprosthesis, analysing the model in Ansys to obtain stress and strain state information. The paper also presents some interesting aspects of the contact between the bone and the implant in case of different types of endoprosthesis (two standardized types and one personalized). A good contact between the bone and the stem indicates a long life solution for an endoprosthesis. A personalized stem is very useful for persons with disabilities is designed taking in consideration the particularities of the patient. The contact results from Ansys illustrate the aspects from the bone stem interface. With this information the orthopaedist can take better decisions for a proper hip joint endoprosthesis used for a named patient.
