OBJECTIVES: Minimally invasive plate osteosynthesis (MIPO) is one of the most recent fixation techniques that embody the concept of biological osteosynthesis. Several studies evaluating MIPO in dogs have been published in the recent years. However, there are few clinical reports of MIPO in cats and no description of the surgical approaches. The purpose of our study was to describe the safe corridors for plate insertion in cats using the MIPO technique. METHODS: The surgical approaches for the humerus, radius-ulna, femur and tibia were developed after reviewing the described techniques and surgical approaches for MIPO in dogs, while considering any relevant anatomical difference between dogs and cats...

The aim of this study was to assess the biomechanical stability of six different osteosynthesis methods after sagittal split osteotomy. Sixty polyurethane hemimandibles were divided into two groups, with six subgroups in each. After 10-mm advancement of the distal segment (group 1) and 10-mm advancement combined with 20° counterclockwise rotation (group 2), the bone segments were fixed using 2.0-mm plates/screws as follows: subgroup A, one conventional straight plate; subgroup B, two conventional straight plates; subgroup C, one conventional sagittal plate; subgroup D, one locking straight plate; subgroup E, two locking straight plates; subgroup F, one locking sagittal plate...

INTRODUCTION: Simultaneous radius and ulna fractures are common in adults and generally osteosynthesis with plating is the treatment of choice. Nailing of such fractures is infrequently advocated. We present our unique technique of radius ulna nailing in adults to achieve closed reduction and early predictable union with minimal or no complications. CASE REPORT: Case 1: 22 year old male with midshaft both bones forearm fracture was treated with stacked nailing. Two 2...

INTRODUCTION: Subtalar dislocation is an uncommon lesion in traumatology chiefly when it concerns the lateral form. Surgical treatment is required when a fracture is related or the dislocation is irreducible. Even well treated, these dislocations progress unavoidably to subtalar arthrosis, which stays well tolerated. CASE REPORT: A 46-year-old male with irreducible lateral subtalar dislocation caused sustentaculum tali incarceration confirmed on computed tomography (CT)...

Partial tibial plateau fractures may occur as a consequence of either valgus or varus trauma combined with a rotational and axial compression component.High-energy trauma may result in a more complex and multi-fragmented fracture pattern, which occurs predominantly in young people. Conversely, a low-energy mechanism may lead to a pure depression fracture in the older population with weaker bone density.Pre-operative classification of these fractures, by Müller AO, Schatzker or novel CT-based methods, helps to understand the fracture pattern and choose the surgical approach and treatment strategy in accordance with estimated bone mineral density and the individual history of each patient...

BACKGROUND: Commonly, intramedullary nails are made of nondegradable materials, and hence they need to be removed once the bone fracture is healed. We propose a novel composite material consisting of poly-L-lactide matrix modified with carbon and alginate fibers to be used for biodegradable intramedullary fixation. The aim of this study was to make in vitro and in vivo biocompatibility assessments. METHODS: In the in vitro conditions, biocompatibility of biomaterials was compared using normal human osteoblasts...

BACKGROUND: Osteoporosis-associated fractures are of increasing importance in trauma surgery. Systematic diagnostics and treatment of osteoporosis during a hospital stay, however, remain inadequate. Therefore, a specific algorithm for diagnosing and treating osteoporosis in trauma surgery patients was developed based on the DVO (German Osteology Society) guideline for osteoporosis from 2014. METHODS: In a first step, the individuals' age and risk profile for osteoporosis is identified considering specific fractures indicating osteoporosis and risk factors assessed by a specific questionnaire...

Isolated mandibular fractures usually represent themselves as non-life-threatening injuries and are not treated in emergency setting. However, some rare patterns of them may result in airway obstruction as a result of displacement of bony fragments. The authors report a patient of an open comminuted fracture of mandibular symphysis which exhibited an uncommon split pattern with retrogression of lingual cortical plate, and thereby induced glossoptosis, painful deglutition, and obstruction of the upper airway within a few hours...

Tooth replacement often leads to inadequate vertical volume in the recipient site bone when a tooth has been extracted because of a vertical root fracture (VRF). This case report presents the autotransplantation of a mandibular third molar (tooth #32) with the attached buccal cortical plate to replace a mandibular second molar (tooth #31) diagnosed with a VRF. After extraction of tooth #31, the recipient socket was prepared based on the size measured in advance with cone-beam computed tomographic imaging. The precise and calculated osteotomy of the cortical bone of tooth #32 allowed for the exact placement of the donor tooth in the position of tooth #31...

INTRODUCTION: Traditional open reduction and internal fixation (ORIF) of extra-articular distal humerus fractures has a risk of iatrogenic radial nerve injury, extensive soft tissue stripping, and long incision scar. We performed an antero-lateral minimally invasive plate osteosynthesis (MIPO) technique with the radial nerve exploration for distal-third diaphyseal fractures of the humerus and evaluated clinical and radiographic outcomes through this respective study. METHODS: From April 2010 to June 2016, 28 cases of extra-articular distal-third diaphyseal fractures were treated with an antero-lateral MIPO procedure...

Thomas S Roukis
Arthrodesis of the first metatarsal-phalangeal joint has been proposed for treatment of severe hallux valgus, end-stage hallux rigidus, rheumatoid arthritis, and revision of failed surgery due to the perceived safety and efficacy. This article discusses the principles of first metatarsal-phalangeal joint arthrodesis in primary and revision situations, joint preparation, configurations of osteosynthesis, and common complications, including salvage of nonunion and revision of malunion with realignment osteotomy...

BACKGROUND: Periprosthetic femoral shaft fractures are a significant complication after total hip arthroplasty (THA). Plate osteosynthesis has been the mainstay of treatment around well-fixed stems. Nonunions are a rare and challenging complication of this fixation method. We report the outcomes of a novel orthogonal plating surgical technique for Vancouver B1 and C-type periprosthetic fractures that previously failed open reduction internal fixation (ORIF). METHODS: A retrospective review identified all patients with Vancouver B1/C THA periprosthetic femoral nonunions from 2010 to 2015...

INTRODUCTION: Tibial diaphyseal fractures are the commonest long bone fractures in adults, most commonly managed by intramedullary interlocking nailing. However, several meta-analysis show that locking plate osteosynthesis is equally effective in managing tibial diaphyseal fractures and are associated with less number of complications. AIM: To compare the results of fixation of tibial fractures following plating and nailing in terms of union, patient satisfaction and complications...
