Results of femoral intramedullary nailing in patients who are obese versus those who are not obese: a prospective multicenter comparison study.

Objectives: Antegrade femoral nailing through a piriformis fossa starting point in patients who are obese has been demonstrated to be problematic. Retrograde femoral nailing therefore has been advocated in this patient population, but little data exist to support such a recommendation. The purpose of this study was to evaluate and compare antegrade and retrograde femoral nailing technique in both patients who are and are not obese.

Trochanteric versus piriformis entry portal for the treatment of femoral shaft fractures.

Objectives: The purpose of this study was to compare results of femoral shaft fracture treatment with nailing through the greater trochanter to nailing through the piriformis fossa with nails specifically designed for each starting point.

Design: Prospective cohort study.

Setting: Four level 1 trauma centers.

Acetabular fractures revisited: a new CT-based classification.

The objective of this investigation is to provide a new CT-based classification of acetabular fractures. The axial CT scans of 112 randomly selected acetabular fracture patients admitted to a Level 1 trauma center between January 1998 and December 2000 were analyzed by an experienced orthopedic trauma surgeon and two experienced emergency radiologists. When available, 3D reformatted images were analyzed as well.

Acetabular fractures revisited: part 2, a new CT-based classification.

Objective: The objective of this investigation was to provide a new CT-based classification of acetabular fractures.

Materials And Methods: The axial CT scans of 112 randomly selected acetabular fractures in patients admitted to a level 1 trauma center between January 1998 and December 2000 were analyzed by an experienced orthopedic trauma surgeon and two experienced emergency radiologists. When available, 3D reformatted images were analyzed as well.

Acetabular fractures revisited: part 1, redefinition of the Letournel anterior column.

Objective: The objective of part 1 of this study is to redefine the Letournel anterior column on the basis of developmental and adult pelvic skeletal anatomy.

Materials And Methods: The axial CT scans of 112 randomly selected patients with acetabular fracture or fracture-dislocations admitted to a level I trauma center between January 1998 and December 2000 were analyzed by an experienced orthopedic trauma surgeon and two experienced emergency radiologists. When available, 3D reformatted images were analyzed as well.

Patient-controlled ropivacaine analgesia after arthroscopic subacromial decompression.

Purpose: To evaluate the efficacy of a subacromial patient-controlled analgesia (PCA) infusion of 0.2% ropivacaine versus saline for postoperative pain control following arthroscopic shoulder surgery.

Type Of Study: Double-blind prospective randomized study.

Mechanical testing of small fracture implants for comparison of insertion and failure torques.

Introduction: Small fracture screws are among the most commonly used implants in the field of orthopedic surgery. The goal of this study was to compare the insertion and failure torques of three screw types: cortical, partially threaded cancellous, and fully threaded cancellous from three manufacturers: Zimmer, Richards, and Synthes.

Materials And Methods: Each type of screw was subjected to biomechanical tests to determine the insertion ( n=6/group) and failure ( n=10/group) torques.

Continuous lumbar plexus block for acute postoperative pain management after open reduction and internal fixation of acetabular fractures.

Objective: To assess the efficacy of postoperative continuous lumbar plexus blocks for postoperative pain control in patients undergoing open reduction and internal fixation of an acetabular fracture.

Patients/participants: Twenty-six patients who underwent open reduction and internal fixation of an acetabular fracture. DESIGN/PERSPECTIVE: According to a case-control study design, patients were divided into 2 groups: Group 1 (n = 13) received postoperatively a continuous lumbar plexus block with 0.
