BACKGROUND Fractures in the distal tibial metaphysis are more complicated to treat than diaphyseal fractures. We compared treatment with plating to treatment with shorted intramedullary (IM) nailing. METHODS Patients with AO type 43A fractures were treated with plate fixation (group A, n=14) or shortened IM nailing (group B, n = 13). We compared(More)
BACKGROUND We compare the use of plate and screws versus intramedullary nails in the operative management of patients with displaced midclavicular fractures. METHODS Between March 2006 and June 2007, we performed a retrospective comparison of a demographically balanced sample of 110 patients (aged 16-65 years) who had received either plates or nails for(More)
BACKGROUND The health-related quality of life (HRQoL) is currently weighted more heavily when evaluating health status, particularly regarding medical treatments and interventions. However, it is rarely used by physicians to compare responsiveness. Additionally, responsiveness estimates derived by the Harris Hip Score (HHS) and the Short Form 36 (SF-36)(More)
This retrospective study investigated adjacent segments radiologically and clinically after posterolateral fusion of the lumbar spine with instrumentation. Thirty-two patients over 60 years old with a postoperative follow-up of at least 4 years were included. These patients all met the criteria of a postoperative symptom-free period of over 2 years, evident(More)
OBJECT The authors measured the range of motion (ROM) of the spine in healthy individuals by using an electromagnetic tracking device to evaluate the functional performance of the spine. METHODS The authors used the Flock of Birds electromagnetic tracking device with 4 receiver units attached to C-7, T-12, S-1, and the midthigh region. Forward/backward(More)
Management for failed hip screw after femoral intertrochanteric fracture is a challenge for orthopaedic surgeons. The unfavorable factors include severe osteoporosis, unstable fracture geometry, improper placement of hip screw, and repeated trauma. Except revision fixation of the fractures, arthroplasty may be indicated in case of destructed femoral head.(More)
Various surgical procedures have been described for the treatment of complete acromioclavicular joint dislocation, but no consensus exists on the optimal therapy. The aim of each type of procedure is to stabilize the clavicle by substitution of the ruptured coracoclavicular ligaments. Treatment modalities have changed with increasing understanding of the(More)
This retrospective study involves 22 patients with displaced tibial plateau fractures who were treated surgically from July 1993 to April 1996. All the patients were over 60 years old (mean 66.3 years old, range 61– 80 years). All of the patients were treated by open reduction and internal fixation with AO/ASIF buttress plates (Synthes, Bochum,(More)
We retrospectively studied 50 patients who underwent salvage procedures for failed compression hip screw (CHS) fixation of intertrochanteric fractures from January 1991 to July 2000. Among these patients, seven underwent revision fixed angle plate surgery; 16 patients underwent bipolar hemiarthroplasty; five patients underwent Austin-Moore hemiarthroplasty;(More)
Tibial intercondylar eminence fractures are uncommon. In a review of the literature, most authors agreed that conservative treatment was suggested for non-displaced fractures. Displaced fractures were considered an indication for surgery. Between April 2000 and November 2001, five adult displaced tibial eminence fractures were treated by arthroscopic(More)
