AIMS: The common treatment for an undisplaced femoral neck fracture is osteosynthesis. Two major complications of osteosynthesis are non-union and late collapse of the femoral head. We speculated that femoral head perfusion is one of the most important factors that affect the outcome of osteosynthesis after femoral neck fracture. We have preoperatively estimated femoral head perfusion by dynamic MRI positive enhancement integral color mapping (PEICM). The purpose of this study was to evaluate the outcomes of undisplaced femoral neck fractures based on PEICM...

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 fracture to any part of their four extremities, clavicle, hand or foot, who underwent surgical plate osteosynthesis from January 2005 to January 2015, and who sustained a subsequent implant breakage...

Osteosynthesis of the distal radius by a volar plate can be complicated by lesions of extensor tendons by screws penetrating the dorsal cortex. The fluoroscopic skyline view enables to confirm the length of the screws. To avoid its risk of irradiation, some authors have recommended to use ultrasound instead. The goal of this study was to demonstrate that the detection rate of screws penetrating the dorsal cortex was at least as good using ultrasound compared to fluoroscopic skyline. A volar plate in which one screw penetrated the dorsal cortex was implanted in 10 cadaveric wrists...

Fractures of the upper limbs are frequent and often need operative treatment in addition to a well-indicated conservative management. This depends on the maturity of the nearest growth plate and the local remodeling potential, which is dependent on age. Following conventional x‑ray imaging an individual prognostic growth analysis leads to the therapeutic decision. Around the elbow and the shaft of the forearm, criteria are stricter than near the shoulder or wrist. Gilchrist or Desault bandages as well as braces are adequate for most subcapital and humeral shaft fractures...

A three-dimensional (3D) digital preoperative planning system for the osteosynthesis of distal radius fractures was developed for clinical practice. To assess the usefulness of the 3D planning for osteosynthesis, we evaluated the reproducibility of the reduction shapes and selected implants in the patients with distal radius fractures. Twenty wrists of 20 distal radius fracture patients who underwent osteosynthesis using volar locking plates were evaluated. The 3D preoperative planning was performed prior to each surgery...

M Rickert, A Meurer
Hemangiomas are benign tumors, which are mainly composed of neoplastic blood vessels. The exact pathogenesis is still unclear. They are the most common benign spinal tumors and also occur less commonly in the bones of the extremities. Hemangiomas are often clinically asymptomatic and are diagnosed as incidental findings. Women are affected more frequently than men (2:1). The X‑ray and computed tomography (CT) diagnostics typically demonstrate the classical honeycombing or vertically orientated lucencies separated by thickened cancellous bone in the affected skeletal section...

INTRODUCTION: Osteosynthesis of femoral neck fractures is related up to 46% rate of complications. The novel method of biplane double-supported screw fixation (BDSF; Filipov's method) offers better stability using three medially diverging cannulated screws with two of them buttressed on the calcar. Biomechanically, the most effective component is the distal screw placed at steeper angle and supported on a large area along the distal and posterior cortex of the femoral neck following its spiral anterior curve...

A lot of research was conducted on the use of various biomaterials in orthopedic surgery. Our study investigated the effects of nanostructured calcium-phosphate coating on metallic implants introduced into the bone marrow canal. Stainless steel or titanium 2-mm wires (groups 1 and 2, respectively), and hydroxyapatite-coated stainless steel or titanium wires of the same diameter (groups 3 and 4, respectively) were introduced into the tibial bone marrow canal of 20 dogs (each group = 5 dogs). Hydroxyapatite coating was deposited on the wires with the method of microarc oxidation...

M Thomas, M Jordan
Severe symptomatic hallux valgus deformities are usually not treatable with conservative methods in the long-term. Surgical treatment currently aims for mechanical restitution of the first ray with preserved mobility of the first metatarsophalangeal (MTP 1) joint and with low risk of recurrence after surgery. Keeping these aims in mind the surgical methods consist of osteotomy at the proximal part of the first metatarsal bone with a high potential for correction of the deformity. Surgical interventions at the midshaft level of the first metatarsal are only useful if the anatomical shape of the metatarsal shows a wide shaft, which allows a large shift in the osteotomy...

PURPOSE: Virtual surgery combined with patient-specific saw and drill guides and osteosynthesis materials are rapidly spreading from reconstructive surgery to orthognathic surgery. Most commercial partners are already providing computer-aided design and computer-aided manufacture (CAD/CAM) wafers and patient-specific saw guides. Clear benefits have been demonstrated for custom-made drill guides combined with individually designed three-dimensional (3D) printed patient-specific implants (PSI) as a reposition and fixation system in Le Fort I osteotomy...

BACKGROUND: Nonoperative treatment has historically been considered the standard for fractures of the shaft of the humerus. Minimally invasive bridge-plate osteosynthesis for isolated humeral shaft fractures has been proven to be a safe technique, with good and reproducible results. This study was designed to compare clinical and radiographic outcomes between patients who had been treated with bridge plate osteosynthesis and those who had been managed nonoperatively with a functional brace...

The os acetabuli is thought to arise from unfused secondary ossification centers or as rim fractures in the setting of dysplastic hips or hips with femoroacetabular impingement. Resection of a large os acetabuli can lead to structural instability of the joint, and in these cases, osteoplasty of the impingement, reduction and internal fixation of the osseous fragment, and labral repair have been described in the literature. Anchor fixation for labral repair in the surrounding zone of the osteosynthesis might bring some technical problems...
