BACKGROUND High-energy trauma to the lower extremity presents challenges with regard to reconstruction and rehabilitation. Failed efforts at limb salvage are associated with increased patient mortality and high hospital costs. Lower-extremity injury-severity scoring systems were developed to assist the surgical team with the initial decision to amputate or(More)
BACKGROUND Limb salvage for severe trauma has replaced amputation as the primary treatment in many trauma centers. However, long-term outcomes after limb reconstruction or amputation have not been fully evaluated. METHODS We performed a multicenter, prospective, observational study to determine the functional outcomes of 569 patients with severe leg(More)
BACKGROUND The use of recombinant human bone morphogenetic protein-2 (rhBMP-2) to improve the healing of open tibial shaft fractures has been the focus of two prospective clinical studies. The objective of the current study was to perform a subgroup analysis of the combined data from these studies. METHODS Two prospective, randomized clinical studies were(More)
BACKGROUND A better understanding of the factors influencing return to work (RTW) after major limb trauma is essential in reducing the high costs associated with these injuries. METHODS Patients (n = 423) who underwent amputation or reconstruction after limb threatening lower extremity trauma and who were working before the injury were prospectively(More)
The system of Gustilo and Anderson for the classification of open fractures is commonly used as a basis for treatment decisions and for comparison of the published results of treatment. The reliability of this classification system was tested on the basis of the responses of 245 orthopaedic surgeons to a survey. The respondents were asked to provide data(More)
OBJECTIVE To measure the failure rate of percutaneous iliosacral screw fixation of vertically unstable pelvic fractures and particularly to test the hypothesis that fixations in which the posterior injury is a vertical fracture of the sacrum are more likely to fail than fixations with dislocations or fracture-dislocations of the sacroiliac joint. DESIGN(More)
BACKGROUND A recent study demonstrated that patients treated with amputation and those treated with reconstruction had comparable functional outcomes at two years following limb-threatening trauma. The present study was designed to determine whether those outcomes improved after two years, and whether differences according to the type of treatment emerged.(More)
BACKGROUND Plantar sensation is considered to be a critical factor in the evaluation of limb-threatening lower extremity trauma. The present study was designed to determine the long-term outcomes following the treatment of severe lower extremity injuries in patients who had had absent plantar sensation at the time of the initial presentation. METHODS We(More)
BACKGROUND Urgent débridement of open fractures has been considered to be of paramount importance for the prevention of infection. The purpose of the present study was to evaluate the relationship between the timing of the initial treatment of open fractures and the development of subsequent infection as well as to assess contributing factors. METHODS(More)
A technique for closed reduction and percutaneous screw fixation of fractures of the iliac wing and fracture-dislocations of the sacro-iliac joint is presented. Twenty-seven pelvic fractures were treated with attempted closed reduction followed by percutaneous screw fixation. Closed reduction failed in two patients. In the other twenty-five, closed(More)
