[Clinical outcome, 6 years after robot assisted hip endoprostheses implantation--a prospective study].

Aim: In our prospective study we evaluated the clinical and radiological results of 36 patients who had a robot-assisted implantation of a cementless hip endoprosthesis.

Method: All patients underwent a standardised examination preoperatively, 1 year after the operation and 6 years postoperatively. We evaluated the pain of the patients with the help of a visual analogue scale, the range of motion of the hip joint and subjective and objective parameters according to the Harris hip score and the Merle d'Aubigné score.

[Modified percutaneous balloon kyphoplasty at osteolysis of 11th thoracic vertebra and communication with the spinal canal. Case report and review of the literature].

This paper presents the case report of a 67-year-old man who came to our hospital suffering from severe osteolysis of the 11th thoracic vertebral body. The patient has been suffering from renal cell carcinoma for 2 years. During a routine control the above-mentioned lesion was found by chance.

The dimensional accuracy for preparation of the femoral cavity in HIP arthroplasty. A comparison between manual- and robot-assisted implantation of hip endoprosthesis stems in cadaver femurs.

Introduction: The aim of the study was to determine the precision of the preparation of the femoral cavity in cementless hip arthroplasty. We compared the bone-prosthesis interface after manual- and robot-assisted implantation of the stems.

Material And Methods: After plastination the specimens were cut to slices of 2.

[Primary rotatory stability of hip endoprostheses stems after manual and robot assisted implantation].

Aim: In our study we compared the primary rotatory stability of hip endoprostheses which were implanted with the help of a robot with that of manually implanted stems.

Method: We examined three different types of prosthesis-stems: Osteolock (Stryker-Howmedica), CBC (Mathys), Excia (Aesculap). Furthermore, we examined two types of prostheses which could not be implanted with a robot (Sl-Plus/Endoplus; Hipstar/Stryker-Howmedica).

[Primary rotatory stability of robot-assisted and manually implanted hip endoprosthesis stems].

In our study we compared the primary rotatory stability of hip endoprostheses implanted with the help of a robot and manually implanted stems. We examined three different types of prosthesis stems: Osteolock (Stryker-Howmedica), CBC (Mathys), and Excia (Aesculap). Ten stems of each prosthesis type were implanted in identical polyurethane foam blocks: five were implanted manually and five with the help of a robot (CASPAR, URS-Ortho).
