Tendon transfer techniques in the foot and ankle are used for tendon ruptures, deformities, and instabilities. This fresh cadaver study compares the tendon fixation strength in 10 paired specimens by performing a tendon to tendon fixation technique or using 7 x 20-25 mm bioabsorbable interference-fit screw tendon fixation technique. Load at failure of the tendon to tendon fixation method averag...

PURPOSE The purpose of this study was to biomechanically evaluate a new technique of intramedullary cortical button fixation for subpectoral biceps tenodesis and to compare it with the interference screw technique. METHODS We compared intramedullary unicortical button fixation (BicepsButton; Arthrex, Naples, FL) with interference screw fixation (Bio-Tenodesis screw; Arthrex) for subpectoral b...

INTRODUCTION: Osteosynthesis plates and screws are used in combination to fix complex fractures. These metallic fixation systems are used with success in healthy bone. But when important stresses apply on the bone-screw interface and when bone is weak, failure of the screw fixation may occur. An obvious mean to improve the fixation of a screw is to augment the surrounding bone with cement. Prev...

The management of intra-articular fractures of the hand represents a challenge. Large articular fragments require reduction and operative fixation. A number of surgical techniques have been described in literature, with variable results. Distal interphalangeal joint fractures have been fixed by various methods including screw, plate and suture techniques. Generally operative fixation is indicat...

A displaced tibial tuberosity avulsion fracture associated with an open extra-articular proximal tibial diaphyseal fracture is an uncommon fracture pattern. This case report describes the successful management of such a fracture pattern in a 45-year old male using an open reduction and lag screw fixation of the tuberosity with a minimally invasive reduction and plate fixation of the proximal ti...

BACKGROUND We aimed to use the animal model of dynamic fixation to examine the interaction of the pedicle screw surface with surrounding bone, and determine whether pedicle screws achieve good mechanical stability in the vertebrae. METHODS Twenty-four goats aged 2-3 years had Cosmic ® pedicle screws implanted into both sides of the L2-L5 pedicles. Twelve goats in the bilateral dynamic fixatio...

background: the accuracy of pedicle screw placement is essential for lumbar and thoracolumbar spine fracture fixation. purpose: the aim of the present study was to assess the accuracy of the pedicle screw placement with conventional c-arm fuoroscopy-guided in these patients. methods: a retrospective review identified patients who underwent operative management with thoracolumbar instruments at ...

AIM Anterior transodontoid screw fixation technique is generally chosen for the management of type II odontoid fractures. The nonunion of type II odontoid fractures is still a major problem especially in elderly and osteoporotic patients. Eleven osteoporotic type II odontoid fracured patients were presented in this article. MATERIAL AND METHODS We have divided 11 patients in two groups as cla...

Minimally invasive osteosynthesis of proximal tibial fractures has grown in popularity in recent years. This article describes a patient with a Schatzker type VI proximal tibial fracture (AO/OTA type 41.C3) and previous compartment syndrome treated with definitive fixation 8 weeks after initial injury with a precontoured proximal tibial plate and a distal targeting device. Brisk bleeding occurr...

Introduction Unilateral pedicle screw fixation and transforaminal cage for interbody fusion are well-established form of treatment for lumbar spondylolisthesis. It is cost effective and has shown to have a comparable outcome to bilateral pedicle screw fixation. We present a case of unilateral pedicle screw fixation and transforaminal cage for interbody fusion in a patient of Grade 1 Degenerativ...
