BACKGROUND Open reduction and internal fixation is the treatment of choice for displaced intra-articular calcaneal fractures at many orthopaedic trauma centers. The purpose of this study was to determine whether open reduction and internal fixation of displaced intra-articular calcaneal fractures results in better general and disease-specific health(More)
BACKGROUND Treatment of fractures is sometimes performed after normal daytime operating hours and in such instances may be performed under less than ideal conditions. The consequence of performing operations under such conditions is largely unknown and was therefore studied in the context of intramedullary nail fixation of tibial and femoral shaft(More)
OBJECTIVE To compare the results of cementless unicondylar knee arthroplasty (UKA) with those already reported in a similar study on cemented UKA. DESIGN A case-series cross-sectional study. SETTING The Queen Elizabeth II Health Sciences Centre, Dalhousie University, Halifax. PATIENTS Fifty-one patients who underwent a total of 57 UKAs between May(More)
A quantitative systematic review of randomized and quasirandomized trials was conducted to determine the effect of surgical versus conservative treatment of acute Achilles tendon ruptures on rates of rerupture. Secondary outcomes included deep infection rates, return to normal function, and minor complaints. A search of computerized databases was conducted(More)
A prospective, randomized, double-blind, multicenter trial was done to determine if the addition of hydroxyapatite and tricalcium phosphate to the porous coating of a cementless femoral component would result in improved clinical and radiographic outcomes. Patients were randomized to receive identical porous-coated stems with (n = 159 hips) or without (n =(More)
BACKGROUND Displaced intra-articular calcaneal fractures are devastating injuries and pose a therapeutic challenge. The purpose of this study was to determine whether open reduction internal fixation (ORIF) plus an injectable bioresorbable calcium phosphate paste (alpha-BSM [bone substitute material]) is superior to ORIF alone in the treatment of calcaneal(More)
Pelvic fractures, especially those of a Malgaigne type, frequently occur in patients who are polytraumatized. Sacroiliac disruption reflects a massive, disruptive energy force with concurrent soft tissue injury. Fixation through an anterior approach facilitates the accurate and stable fixation and avoids many soft tissue wound problems associated with open(More)
Pelvic fractures with disruption of the important weight-bearing sacroiliac area can lead to impaired gait due to malunion or pelvic obliquity, back or buttock pain arising from the sacroiliac joint, and permanent neurologic damage. In eight patients with sacroiliac joint dislocation, an anterior retrofascial approach and stapling of the sacroiliac joint(More)
We measured femoral intramedullary pressures and applied axial thrust force generated in vitro during reaming with the AO and Zimmer systems. Six pairs of cadaver femora were instrumented with pressure taps midshaft and in the distal diaphysis, a load cell distally to measure force, and a displacement transducer to monitor reamer position. Following initial(More)
STUDY DESIGN This is a retrospective single-patient case report with a literature review. OBJECTIVE To report on an uncommon injury: traumatic fracture-dislocation of the lumbosacral junction with delayed displacement. SUMMARY OF BACKGROUND DATA Only 31 cases of traumatic fracture-dislocation of the lumbosacral junction were found in the English(More)
