Novel Interlocking Nail Explantation Utilizing Custom-Made Jig and Cortical Bone Windowing Technique in a Dog

Distal intramedullary nail interlocking: the flag and grid technique.

Distal interlocking in intramedullary nailing of long bone fractures accounts for a significant proportion of the total fluoroscopy and operative time. We describe a modification of the "perfect circles" freehand technique employing a metallic grid temporarily attached to the skin of the lateral surface of the femur or to the medial surface of the tibia that acts as a fixed "navigational" aid. ...

Extraction of broken interlocking tibial nail without opening the fracture - Nail in Nail technique: A simpler and cost effective solution

The removal of the distal fragment of broken intramedullary nail often poses an important technical challenge. Many methods have been published on the removal of the distal piece of a broken distal closed section intramedullary nail that involve the use of hooks, olive wires or special instruments that are often not available to the general orthopedist working in a smaller setup. Additionally, ...

Assessment of osteonal and interstitial bone quality using a novel custom-made microscope-indenter assembly

INTRODUCTION: Prediction of bone fracture goes beyond bone mineral density measurement. The quality of bone matrix is instrumental in providing fracture resistance to bone. Thus assessment of bone quality is critical to understanding bone fracture. Reference point indentation (RPI) purports to measure bone matrix quality in vivo and has been shown to separate fracture and non-fracture groups wi...

A New Surgical Technique in Treatment of Nail Onycogryphosis

Risk of periprosthetic femur fracture after anterior cortical bone windowing

BACKGROUND AND PURPOSE Removal of distal cement at femoral implant revision is technically challenging and is associated with complications such as cortical perforations. A technique that can reduce the risks and operating time is to make a small cortical window in the distal femur for enhanced access. We wanted to determine whether the use of long, bridging, cemented femoral stems is necessary...
