Fibrous dysplasia is a benign developmental disorder of bone in which fibrous connective tissue containing abnormal bone with irregular trabeculae replaces normal cancellous bone. It may affect 1 (monostotic) or multiple bones (polyostotic). Polyostotic disease is the less common of the 2, occurring in only 20 to 25% of fibrous dysplasia patients and tending to affect those who are younger than 10 years of age; patients having this form tend to experience bone enlargement beyond normal skeletal maturation, which can cause pain, progressive damage, and increased risk of pathological fracture...

Central neurocytomas (CNs) are rare benign tumors located in the central nervous system with a good prognosis. These tumors are predominantly located in the lateral ventricle near the foramen of Monro or in the third ventricle. Similar tumors that are located outside the ventricle are also called extraventricular neurocytomas, and have an even lower morbidity. Until now, several tumors have been identified in the thalamus, cerebellum, pons, medulla oblongata and spinal cord. In total, 24 cases of neurocytomas located in the spinal cord have been reported in English journals...

The constructive interference in steady state (CISS) sequence has been widely used in human neuroimaging. It has been shown to be advantageous in the evaluation of intra-axial and extra-axial cystic abnormalities, arteriovenous and dysraphic malformations and disturbances of cerebrospinal fluid circulation. To assess the utility of this technique in small animals, interpretations based on this sequence were compared with those based on T2-weighted (T2W) sequences in 145 dogs that underwent MRI of the spine for suspected spinal cord disease...

Today intramedullary nails (IMN) are the gold standard in the treatment of femur fractures. Since its inception, improved design and understanding of the surrounding anatomy has exponentially increased successful patient treatment and outcomes by promoting early mobilization and reliable union. In this review, we provide an in-depth look into the evolutionary process that has led IMN to becoming today's gold standard in femur fractures.

Distal Chevron osteotomy is a well-established surgical procedure for mild to moderate hallux valgus deformity. Many methods have been described for fixation of osteotomy site; secure fixation, enabling large displacement of the metatarsal head, is one of the essentials of this procedure. The purpose of the present study was to evaluate the short-term radiographic outcome of a distal Chevron osteotomy using an intramedullary plate for the correction of hallux valgus deformity. The present study evaluated 37 patients (40 feet) who underwent distal Chevron osteotomy using an intramedullary plate by periodic radiographs obtained preoperatively and at 4 weeks, 8 weeks, 3 months, and 6 months postoperatively...

Purpose  The purpose of our study is to compare the intramedullary fixation of metacarpal fractures with cannulated headless screws and antegrade Kirschner wires in terms of final total active motion, grip strength, patient-related outcomes, need for casting, and return to work times. Methods  The authors performed a retrospective review of the hospital records. Thirty fractures were included in the study, 19 in the screw fixation group, and 11 in the Kirschner wire group. Grip strength, and total active motion, was measured at the latest follow-up for both the injured and contralateral hand...

OBJECTIVES: The best fixation method for open tibial fractures has long been a matter of debate, many studies have recommended the use of intramedullary nails over external fixation for treating such fractures, recent studies also showed favorable results for the use of plates in managing open tibial fractures. However, there are very few (if any) reports in the literature comparing the use of minimally invasive plate osteosynthesis to reamed intramedullary nails in the fixation of open tibial fractures...

BACKGROUND: Bone metastases represent the most frequent cause of cancer-related pain, affecting health-related quality of life and creating a substantial burden on the healthcare system. Although most bony metastatic lesions can be managed nonoperatively, surgical management can help patients reduce severe pain, avoid impending fracture, and stabilize pathologic fractures. Studies have demonstrated functional improvement postoperatively as early as 6 weeks, but little data exist on the temporal progress of these improvements or on the changes in quality of life over time as a result of surgical intervention...

PURPOSE: Surgical treatment of displaced midshaft clavicle fractures requires a decision between plate fixation and intramedullary (IM) fixation. Numerous studies report on the biomechanical properties of various repair constructs. The goal of this systematic review was to provide an overview of studies describing the biomechanical properties of the most commonly used surgical fixations of midshaft clavicle fractures. Additionally, we aimed to translate these biomechanical results into clinically relevant conclusions...

With an aging population, treatment of interprosthetic femur fractures continues to pose a challenge to the orthopedic surgeon. Retrograde IMN combined with open reduction internal fixation utilizing a tissue-preserving plating technique was used in our series of 9 patients with non-comminuted, distal femur fractures. No interfragmentary screws, cables, cerclage wires, or supplemental bone grafts of any type were used. Each patient initiated weight-bearing as tolerated following operative intervention. Every fracture healed at an average of 20 weeks (range 18 to 24 weeks)...

A neutered male Siberian tiger ( Panthera tigris altaica) presented with paraplegia of 5 days' duration. Thoracolumbar magnetic resonance imaging (MRI) revealed a focal, linear T2-W hyperintense intramedullary lesion at the level of T10-11 as well as reduced size of the nucleus pulposus of the T10-11 intervertebral disc. The animal was humanely euthanatized as a result of the severity of clinical signs and the poor prognosis. Gross necropsy revealed a dark red, firm focus on the spinal cord at the level of the T11 nerve roots...

A 79-year-old man presented with primary intramedullary malignant lymphoma with a presyrinx state in the cervical cord manifesting as left hemiparesis and hemidysesthesia. The magnetic resonance imaging (MRI) scan showed an intramedullary mass in the cervical spinal cord at the level of C1 and T2-weighted image prolongation from the medulla to the level of C5. According to the progression of hemiparesis, he underwent an emergency removal of the tumor under general anesthesia. The tumor was totally removed, and the peritumoral signal abnormality was not present in the postoperative MRI...

Multiple methods have been described for treating unstable proximal and middle phalangeal fractures. Irrespective of using an open or closed technique of fixation, stiffness and extensor lag at the proximal/distal interphalangeal joint almost always occur. This issue can be avoided by allowing the patients to mobilize the fingers out of plaster or splint as early as possible from the day of surgery. We describe a technique of intramedullary percutaneous fixation of extra-articular proximal and middle phalanx fractures allowing immediate mobilization of fingers, concurrent stabilization with progressive healing and thus preventing such complications...

We analyzed the results of 20 unstable metacarpal fractures in 15 patients treated with a cannulated compression screw and no immobilization. All fractures healed within 6 weeks. One patient with multiple fractures and a flexion deficit required arthrolysis of two metacarpophalangeal joints. Another patient had an extension lag. There were no other complications. This fast and easy technique results in good outcomes for unstable metacarpal fractures. The advantages are early active motion without immobilization and stable fixation...
