BACKGROUND Proximal femoral nail antirotation devices (PFNAs) are considered biomechanically superior to dynamic hip screws for treating unstable peritrochanteric fractures and reportedly have a lower complication rate. The PFNA II was introduced to eliminate lateral cortex impingement encountered with the PFNA. However, it is unclear whether the new design(More)
In a prospective study, the authors used a porous tantalum monoblock acetabular component for primary total hip arthroplasty between November 1997 and June 1999. A total of 156 consecutive primary total hip arthroplasty were done in 143 patients younger than 75 years. A total of 151 hips had a follow-up time from 8 to 10 years. The average preoperative(More)
BACKGROUND This retrospective study was undertaken to determine the incidence of kidney dysfunction (KD) and to identify potential risk factors contributing to development of KD in orthopaedic population following an elective or emergency surgery. METHODS A total of 1025 patients were admitted in our institution over a period of one year with various(More)
Fifteen patients with Neer type II distal clavicle fracture were treated surgically. Operative treatment included open reduction and fixation of the proximal clavicular fragment to the coracoid process using a 6.5-mm cancellous screw and repair of the coracoclavicular ligaments. Fracture union occurred at a mean of 7 weeks postoperatively without any(More)
Between January 1998 and December 1998, 82 consecutive patients (86 hips) underwent total hip arthroplasty using a trabecular metal monoblock acetabular component. All patients had a clinical and radiological follow-up evaluation at six, 12 and 24 weeks, 12 months, and then annually thereafter. On the initial post-operative radiograph 25 hips had a gap(More)
In order to compare short-segment stabilization with long-segment stabilization for treating unstable thoracolumbar fractures, we studied fifty patients suffered from unstable thoracolumbar burst fractures. Thirty of them were managed with long-segment posterior transpedicular instrumentation and twenty patients with short-segment stabilization. The mean(More)
Deep periprosthetic hip infection is a devastating complication. Goal of treatment is infection eradication and durable functional reconstruction. Two-stage re-implantation is the standard of treatment. From January 1998 to December 2004 we treated 38 patients with an infected THA. There were 24 females and 14 males, with a mean age of 67 years (61-75). The(More)
Despite modern surgical techniques and advanced antimicrobial therapy, open lower-extremity fracture management and osteomyelitis remain a challenge for reconstructive surgeons. Posttraumatic composite bone and soft tissue defects are usually the result of high-energy trauma and are often associated with concomitant injuries, therefore making complex(More)
BACKGROUND Fractures of the distal radius are among the most common fractures in orthopedic practice. The purpose of our study was to explore the advantages and disadvantages of two methods of treatment for this type of fracture. METHODS One hundred thirteen fractures of the distal radius have been operated; 49 fractures were treated with an external(More)
We report the long-term results of the management of neglected chronically infected total knee replacements with a two-stage re-implantation protocol. In 18 of 34 patients (53%) a resistant organism was isolated. All cases were treated by the same surgical team in a specialist centre and had a mean follow-up of 12.1 years (10 to 14). They were evaluated(More)
