In a prospective randomized study, we compared the results after implantation of the mobile bearing high flex TKA with a fixed bearing posterior stabilized TKA in 60 patients (30 patients each group). We evaluated the hospital for special surgery-score (HSS) and different radiological parameters preoperatively, as well as 3 months, 3 and 5 years(More)
AIM Short-stemmed prostheses are increasingly regarded as implants of first choice in coxarthrosis, especially in young patients. Despite promising short-term results, long-term follow-up studies are still lacking. Short-stemmed femoral implants are characterised by a metaphyseal osseointegration and strain distribution. Therefore a reduced stress shielding(More)
To evaluate the effectiveness of the Bipolar Sealer 6.0-VT (BPS 6.0-VT) (Tissue Link Medical, Inc, Dover, NH) in reducing blood loss compared with a conventional electrocautery (Erbe ICC 350) (Erbe ICC 350 (ERBE Elektromedizin GmbH, Tübingen, Germany). A prospective randomized trial of 105 patients with primary total hip arthroplasty (Erbe ICC 350: 50(More)
BACKGROUND Up to 80% of professional musicians are affected by playing-related musculoskeletal disorders, but data regarding the frequency of craniomandibular dysfunction (CMD) in professional orchestra musicians is scarce. AIMS To evaluate the frequency of CMD and its relation to musculoskeletal pain in various body regions. METHODS A(More)
The aim of this prospective study was to assess the range of motion (ROM) achieved with the Genesis II Posterior Stabilized High Flexion knee prosthesis. The ROM was compared with that of a historical study group with the standard PS insert and an identical study design. Sixty three patients with primary knee osteoarthritis (37 female, 26 male; average age:(More)
Computer-assisted navigation in total knee arthroplasty has been shown to improve implant positioning and may lead to improved patient outcomes. The purpose of this study was to assess differences in time and accuracy using a navigation system with either a conventional (20 knees) or specially designed (20 knees) system of cutting blocks. The time needed(More)
The flexible Triac-Brace was developed to improve cosmetic appearance and wearing comfort. It was evaluated in this study with respect to primary curve correction in idiopathic scoliosis (IS). Twenty patients (15 girls, 5 boys, mean age: 12.5) with a diagnosis of IS were treated with the Triac-Brace. Lumbar curves showed an initial average Cobb angle of 26(More)
Ziel der Studie war, die biomechanischen Auswirkungen der flexiblen Krallenzehkorrektur durch Sehnentransfer nach Girdlestone-Taylor mittels dynamischer pedobarographischer Untersuchung zu analysieren. Zwölf Patienten wurden präoperativ und 12 Monate postoperativ klinisch und durch den AOFAS-Score (American Orthopaedic Foot and Ankle Society) evaluiert. Die(More)
In total hip endoprosthetics and consequently for TDA, metal-on-metal combinations are used with the aim of reducing wear debris. In metal-on-metal TDA the release of metal ions has until now been secondary to the main discussion. In order to investigate the ion release following the implantation of the metal-on-metal Maverick™ type artificial lumbar disc(More)
The aim of this study was to analyze the bone remodeling around the Nanos stem (Smith & Nephew, Marl, Germany) after primary total hip arthroplasty for coxarthrosis. In 25 patients (15 male, 10 female, mean age 59.9 years) with the diagnosis of coxarthrosis, a DEXA scan was performed immediately after surgery, 97 days (SD 6.1 days) and 368 days (SD 6.2(More)
