Traditional methods of correcting malunited distal humeral fractures in children involve complex wedge osteotomies held with pins or internal fixation devices. These require a large exposure and challenging fixation. We elected to perform simple transverse osteotomies, without wedges, using a lateral incision. These were maintained by the small AO external fixator. Between 1987 and 2004, five c...

BACKGROUND The optimal treatment of type III pilon fractures remains controversial. Hence, we performed this study to investigate whether open reduction and internal fixation (ORIF) is superior to external fixations combined with limited internal fixations (EFLIF). MATERIAL AND METHODS From January 2012 to October 2013, a total of 78 patients were included. Twenty-six patients underwent EFLIF...

Here are reported data on virulence determinants of Staphylococcus aureus from orthopedic surgical infections, emphasizing on the genes encoding fibronectin (fnbA, fnbB) and collagen (cna) adhesins. 191 S. aureus strains from orthopedic infections (53 from internal fixation devices, 29 external fixation devices, 15 knee arthroprostheses, 30 hip arthroprostheses, 45 surgical reconstruction and 1...

The paper outlines recent results from experiments devoted to evaluate the instrumental performance of Bragg-Brentano geometry based diffractometers. Reproducibility, repeatability, and accuracy increased when calibration procedures are taken into account. The evaluation of internal consistency is required for a good quality calibration process, a good check of the optical alignment, and accura...

A prospective randomised trial of surgical treatment for the displaced subcapital femoral fracture in patients of 70 years or more is presented. Two hundred and eighteen patients were randomly allocated into one of three treatment groups: manipulative reduction and internal fixation using Garden screws; Thompson hemiarthroplasty through a posterior (Moore) approach; and Thompson hemiarthroplast...

An experimental study is reported of fracture healing in the femora of 36 Beagle dogs, comparing the results of using stainless steel plates with those of using less rigid titanium alloy plates. The alloy plates led to the appearance of a small amount of periosteal callus without any histological evidence of fracture instability, thus allowing the radiological assessment of fracture union. This...

Failure of internal fixation following treatment of a fracture or fracture nonunion presents a challenging clinical situation. In certain cases, Ilizarov external fixation may be the preferred method to treat bony injuries that have failed to unite following one or more attempts at internal fixation. This paper reviews the modes of failure following internal fixation, revision internal fixation...

OBJECTIVES The monitoring of fracture healing is a complex process. Typically, successive radiographs are performed and an emerging calcification of the fracture area is evaluated. The aim of this study was to investigate whether different bone healing patterns can be distinguished using a telemetric instrumented femoral internal plate fixator. MATERIALS AND METHODS An electronic telemetric s...

Rigid internal fixation with plates and screws is now standard for the treatment of fractures, osteotomies and reconstruction of the craniomaxillofacial skeleton. The latest innovations are self-drilling, self-tapping screws and locking miniplates. These screws offer the prospect of less instrumentation and faster application. Preclinical testing has shown them to be substantially more retentiv...

BACKGROUND Implant breakage after the fixation of traumatic fractures is rare; however, when it occurs, it is debilitating for the patients and a challenge for surgeons. The purpose of this study was to analyze and identify the independent risk factors for implant breakage of traumatic fractures treated with plate osteosynthesis. METHODS We reviewed the medical records of patients with a frac...
