PURPOSE: There are two widely used distal humerus fracture (DHF) fixation methods with either orthogonal or parallel double-plate osteosynthesis. However, biomechanical studies have shown inconsistent results on which technique is more effective. We performed a meta-analysis to compare these two fixation methods for adult DHF fixation. METHODS: We searched the literature for entries discussing the biomechanical testing of orthogonal and parallel fixation techniques for DHFs...

BACKGROUND: There is a high incidence of blood transfusion following hip fractures in elderly patients. AIM: The aim of this study is to evaluate the effectiveness and complications of use of tranexamic acid in proximal femur nailing surgery. MATERIALS AND METHODS: Our sample group consisted of 90 patients suffering from pertrochanteric fractures surgically treated with osteosynthesis with SupernailGT(LimaCorporate). The classification system AO/OTA was used to divide the fractures into 31A1 (n=45) and 31A2 (n=45)...

BACKGROUND: Minimally invasive percutaneous plate osteosynthesis (MIPPO) has begun to be used in fractures of the lateral malleolus surgeries in recent years as for fractures in other regions. However, for MIPPO techniques applied to fractures of the lateral malleolus there is no external guide for plate insertion, determining the incision and inserting the screws as used for fractures in other regions. With the MIPPO technique fluoroscopy exposure is unavoidable. The MIPPO technique is advantageous for patients; however the unavoidable problem with this treatment method for the surgical team is exposure to fluoroscopy with every case...

BACKGROUND: The Morel-Lavallée lesion is one of the concomitant soft tissue lesions of pelvic fractures. Its role in spine fractures and its treatment in combination with osteosynthesis of pelvic or spine fractures have not yet been determined. The aim of this study was to analyse the best diagnostic and treatment options of both spine and pelvic fractures combined with Morel-Lavallée lesions (MLL). METHODS: An analysis of the literature was performed via PubMed and Medline...

BACKGROUND CONTEXT: In patients with Mucopolysaccharidosis (MPS), glycosaminoglycans deposits in the dura mater and supporting ligaments cause spinal cord compression and consecutive myelopathy, predominantly of the cranio-cervical junction. Disease characteristics of cranio-cervical stenosis (CCS) in MPS patients differ profoundly from other hereditary and degenerative forms. Due to high peri-procedural morbidity and mortality, MPS patients pose a substantial challenge to the unexperienced medical care provider...

Pertrochanteric femur fractures are considered amongst the most commonly encountered fractures in the geriatric age group. We evaluated radiographic and functional outcomes of patients with unstable pertrochanteric fractures treated with the proximal femur nail antirotation (PFNA). Between March 2013 and December 2015, fifty patients (28 male and 22 females with a mean age of 72.8 years (range, 20-94)) with unstable pertrochanteric fractures (AO 31.A2 and 31.A3) were fixed with the PFNA at our institution, and they were retrospectively evaluated...

This surgical technical case report presents initial clinical experience and preliminary results with a less invasive surgical solution for selected hangman's fracture. A well-known stabilization technique (i.e. direct transpedicular osteosynthesis) was applied through a minimally invasive small incision transmuscular posterior approach guided by a standard C-arm fluoroscopy. This mini-open approach to C2 vertebra allows similar dissection, visualization of the bony landmarks, visual control of the transpedicular screw path drilling, tapping and screw insertion to the standard posterior cervical spine approach...

Bone healing models are necessary to analyze the complex mechanisms of fracture healing to improve clinical fracture treatment. During the last decade, an increased use of mouse models in orthopedic research was noted, most probably because mouse models offer a large number of genetically-modified strains and special antibodies for the analysis of molecular mechanisms of fracture healing. To control the biomechanical conditions, well-characterized osteosynthesis techniques are mandatory, also in mice. Here, we report on the design and use of a closed bone healing model to stabilize femur fractures in mice...

Deepak Gautam, Rajesh Malhotra
Massive skeletal defects are encountered in the setting of tumors necessitating excision, failed total hip arthroplasty with periprosthetic bone loss, periprosthetic fracture, complex trauma, multiple failed osteosynthesis and infection. Reconstruction of the segmental defects poses a tremendous challenge to the orthopaedic surgeons. The goal of osseous reconstruction of these defects is to restore the bone length and function. Currently the most commonly employed methods for reconstruction are either a megaprosthesis or an Allograft Prosthesis Composite (APC)...

We present a rare case of traumatic bilateral asymmetric hip dislocation with pelvic fractures and a traumatic diaphragmatic hernia. A 53-year-old machinist was transferred to our emergency department with the suspicion of a bilateral hip dislocation after he was trapped between an elevator and the roof. Immediate closed reduction of the hips was not performed because of the expected risk of increasing hemodynamic instability with muscular relaxation. An emergent full-body computed tomography (CT) scan was made to assess injuries with need for further operative treatment...

Spinopelvic injuries result from high energy trauma with overloading through the sacrum. These lesions can accomplish either bone fractures, ligament injuries or, most commonly, both. They may be accompanied with other associated life threatening injuries and cause biomechanical instability with potential fracture non-union, mal-union and subsequent lifetime pain and disability. Surgical stabilization of spinopelvic injuries requires planning in order to apply the appropriate osteosynthesis principles (compression; neutralization; buttressing and tension band)...

BACKGROUND: Implant-related infections, including those of peri-prosthetic joint (PJIs), osteosynthesis and other biomaterials, are biofilm-related. Pathogen identification is considered the diagnostic benchmark; however, the presence of bacterial biofilms makes pathogen detection with traditional microbiological techniques only partially effective. To improve microbiological diagnostic accuracy, some biofilm debonding techniques have been recently proposed. Aim of this health economics assessment study was to evaluate their economic impact on hospital costs...

INTRODUCTION: Supracondylar fracture of the humerus can be considered the most serious fracture in childhood. Problems with its diagnostics and treatment as well as its complications and sequels have not been fully solved yet. That is evidenced by a large amount of articles with frequently inconsistent conclusions. The aim is to evaluate contemporary diagnostic and therapeutic approach based on our own clinical experience. METHODS: A total of 2847 children with skeletal injury were treated by the authors during the year 2016...
