Proximal femoral allograft treatment of Vancouver type-B3 periprosthetic femoral fractures after total hip arthroplasty. Surgical technique.

Background: Periprosthetic femoral fractures following total hip arthroplasty are becoming more prevalent. When a fracture occurs in a femur with substantial proximal bone deficiency, the surgical options for revision are limited. One option includes the use of a proximal femoral allograft.

A large-scale statistical analysis of barefoot impressions.

In an earlier paper, outlines of footprints of persons walking normally were studied to determine whether different people make verifiably distinct footprints. Our basic null hypothesis is: given a footprint outline trace made by Subject A (Alice), then Subject B (Bob), a distinct person, cannot produce a footprint outline trace indistinguishable from that of Alice. We showed in the previous work that the probability of a chance match is less than 10(-8).

Modified sliding trochanteric osteotomy in revision total hip arthroplasty.

Traditional trochanteric sliding osteotomy preserves the lateral aspect of the greater trochanter, the abductors, and vastus lateralis in continuity. Our modification uses a lateral approach to the hip and osteotomy immediately anterior to the insertion of the posterior capsule and external rotators onto the greater trochanter. The osteotomy and attached abductors and vastus lateralis are translated anteriorly, leaving the posterior capsule and external rotators attached to the proximal femur.

Management of periprosthetic femoral fractures after total knee arthroplasty using a distal femoral allograft.

This study is a review and discussion of 12 consecutive patients who were revised with a distal femoral allograft for periprosthetic supracondylar fractures of the femur associated with poor bone quality by the same surgeon between 1990 and 2001. Two were lost to follow-up. The average age was 65 years, and the mean follow up was 6 years.

Acetabular metastases: planning for reconstruction and review of results.

The treatment of acetabular bone metastases presents numerous clinical challenges including the necessity for careful patient selection for surgery, determination of the extent of bone destruction, and providing the patient with stable surgical reconstruction of the pelvis. There are relatively few patient series reported in the literature to inform treatment planning, surgical reconstruction techniques, and patient outcomes. We describe a rationale for assessment of patients with acetabular metastases and options for reconstruction.

Long-term follow-up of fresh tibial osteochondral allografts for failed tibial plateau fractures.

Background: The management of large posttraumatic full-thickness osteochondral defects in the proximal part of the tibia remains a challenge. The goal of treatment is a pain-free range of motion of the knee that provides enduring function and enables a young patient to participate in a wide range of activities. The use of fresh osteochondral allograft transplantation for tibial plateau lesions has been well documented.

A review of ski injuries resulting in combined injury to the anterior cruciate ligament and medial collateral ligaments.

Alpine skiing is a global winter recreational sport with 15 million participants in the United States alone, and an overall injury rate of 2.5 per 1,000 ski person-days. Isolated injury to the anterior cruciate ligament (ACL) or the medial collateral ligament (MCL) is common among ski injuries; however, combined injury to these structures is rare.

Statistical analysis of barefoot impressions.

Comparison of the shapes of barefoot impressions from an individual with footprints or shoes linked to a crime may be useful as a means of including or excluding that individual as possibly being at the scene of a crime. The question of the distinguishability of a person's barefoot print arises frequently. This study indicates that measurements taken from the outlines of inked footprint impressions show a great degree of variability between donors and a great degree of similarity for multiple impressions taken from the same donor.
