Helical Blade or the Integrated Lag Screws: A Matched Pair Analysis of 100 Patients With Unstable Trochanteric Fractures.

Objectives: To compare the radiological and clinical results with PFNA-II and InterTan in the treatment of unstable trochanteric fractures in the elderly.

Design: Retrospective, multicenter, matched pair.

Setting: Three tertiary level trauma centers.

A novel MIS technique for posterior cruciate ligament avulsion fractures.

Objective: Open surgical approaches to treat tibial avulsion fractures of the posterior cruciate ligament (PCL) often use large incisions involving extensive muscle dissection and retraction. The objective of this study was to describe a new mini-invasive approach targeting the fractured zone, to minimize surgical dissection and improve recovery and rehabilitation.

Methods: The new approach was used in 15 males and seven females with isolated PCL avulsions.

Transplantation of autologous chondrocytes expanded using Thermoreversible Gelation Polymer in a rabbit model of articular cartilage defect.

Graft failure due to de-differentiation of the chondrocytes during in vitro culture and after transplantation is a major hurdle in Autologous Chondrocyte Implantation (ACI). We, herein, report the transplantation of autologous chondrocytes expanded using a Thermo-reversible Gelation Polymer (TGP) in a rabbit model. A full thickness chondral defect was created in one of the knee joints in each of the six rabbits of the study and autologous chondrocytes expanded using TGP scaffold were transplanted after 10 weeks.

Delayed Total Hip Arthroplasty for Failed Acetabular Fractures: The Influence of Initial Fracture Management on Outcome After Arthroplasty.

Background: Total hip arthroplasty (THA) provides a successful salvage option for failed acetabular fractures. The complexity of arthroplasty for a failed acetabular fracture will depend on the fracture pattern and the initial management of the fracture. Our objective was to compare the midterm outcome of THA between patients who presented with failed acetabular fractures following initial surgical or nonsurgical treatment.
