A 6 mo old 13.5 kg (29.7 lb) male intact American Staffordshire terrier was evaluated for a history of supernumerary pelvic limbs, with malodorous discharge from a supernumerary penis. Imaging (radiographs, abdominal ultrasound, and computed tomography with excretory urogram) showed a supernumerary pelvis with associated pelvic limbs, no osseous continuity with the primary spinal column, a colonic diverticulum extending to the supernumerary pelvis, an enlarged left kidney with a ureter connecting to a single bladder, right renal aplasia, a single descended testicle in the primary scrotum, an intra-abdominal cryptorchid testicle, and two unidentifiable soft tissue masses...

OBJECTIVE: The demographic change in the population leads to a rising number of patients presenting with fractures of the cervical spine, especially C-2, due to falls. With an increase of co-morbidities in these elder patients, the risk for intra- and postoperative complications is increased likewise. Thus, an alternative strategy instead of operative management of these fractures should be taken into account whenever possible. Conservative management of dens fractures in the elderly is still a subject of great controversy despite numerous studies on this topic...

PURPOSE: Greater tuberosity fractures (GTFs) account for 17 to 21% of proximal humerus fractures, most of these fractures are treated conservatively, but treatment for displaced fractures is still controversial. The aim of this study is to compare intra-operative clinical conditions and post-operative outcomes when displaced GTFs are treated with either proximal humeral internal locking system (PHILOS) or mini locking plate with trans-osseous sutures. METHODS: This is a retrospective study conducted in Shanghai Tenth People's Hospital...

Intra-osseous cholesterol granuloma (CG) is a rare and benign lesion. Very few cases of CG of the jaws have been described in the literature. CG of the jaws seems to be due to the accumulation of cholesterol of hematogenous origin in odontogenic cysts. We report on one case of CG of the maxilla treated by surgical enucleation in a 46-year-old man who presented an asymptomatic swelling of the maxilla.

Intra-articular injection of corticosteroid and anesthetic (CSI) is a useful diagnostic tool for hip pain secondary to labral tears or femoroacetabular impingement (FAI). However, the effectiveness of CSI as a stand-alone treatment for hip pain in adolescents is unknown. The purpose of this study is to evaluate the use of CSI for the treatment of hip pain and determine factors that may affect outcomes after injection. Retrospective analysis of 18 patients and 19 hips that underwent fluoroscopic guided hip injection for the treatment of pain at a single institution from 2012 to 2015 was carried out in this study...

BACKGROUND: Arthrodesis of the first metatarsophalangeal joint (MTPJ) is a common procedure to treat significant first MTPJ arthritis. However, dorsal plates used for this have been associated with high incidence of metalwork removal. The IOFIX (Intra-Osseous FIXation) is a fixed angle device that is noted to provide a more uniform compression over a larger aspect of the fusion surfaces than a screw construct alone with the advantage of minimizing soft tissue irritation which can reduce the need for subsequent implant removal...

Minimally invasive procedures play a crucial role in the diagnosis and treatment of many pediatric musculoskeletal conditions. Although computed tomography and fluoroscopy are commonly used for image guidance, the associated exposure to ionizing radiation is especially concerning in pediatric patients. Ultrasonography may be used successfully in a subset of interventions, but it is often not useful for complex, deep, and osseous targets. Interventional magnetic resonance imaging (iMRI) facilitates targeting and treatment of musculoskeletal lesions at many locations with high accuracy due to its excellent tissue contrast...

WE43 Mg alloy, composed of Mg, Yttrium, Rare Earth elements, and Zirconium, has proved to be a suitable candidate for production of resorbable osteosynthesis implants in both clinical and experimental settings. In a previous study we tested biocompatibility and degradation properties of untreated (as-cast) and artificially aged (T-5) WE43 Mg-alloys as subperiosteal implants on a maxillofacial sheep model. Both the alloy compositions showed excellent biocompatibility, however, with respect to degradation rate, the as-cast form showed increased degradability compared with the T-5...

BACKGROUND: Proximal humeral fracture is a common fracture. Different approaches have been utilized in the surgical intervention of three-part fractures. Our study is to evaluate the clinical outcomes and effectiveness of a modified anterolateral approach and intra-osseous portal in minimally invasive treatment for three-part proximal humeral fractures in comparison to the traditional deltopectoral approach. METHODS: From March 2015 to September 2016, 13 patients with three-part proximal humeral fractures were treated with internal fixation through the modified anterolateral minimally invasive approach (MIPO)...

BACKGROUND: Pseudomeningoceles most commonly occur due to prior trauma or surgery and are often located in the posterior paraspinous tissues. Here, we report a case of an intraosseous pseudomeningocele that mimicked an intra-osseous T2 hyperintense lesion in the L1 vertebral body. CASE DESCRIPTION: A 64-year-old male presented with back, left lateral thigh and left knee pain lasting several months. He had no prior history of trauma or surgery. Radiographs of the lumbar spine showed mild levoscoliotic curvature of the lumbar spine, Baastrup's changes between the spinous processes, multilevel degenerative disc disease and facet arthropathy...

BACKGROUND: Traumatic posterior hip dislocations in children and adolescents requires emergent closed reduction. Postreduction imaging is necessary to assess the concentricity of reduction and structural injuries to the hip. There is no a consensus for which imaging is a modality of choice in such condition. The purposes of this study are to describe magnetic resonance imaging (MRI) findings of traumatic posterior hip dislocations and to compare the effectiveness of MRI with computerized tomography (CT) in detecting structural abnormalities of the hip that impact patient management...

BACKGROUND: Navigated total hip arthroplasty (THA) can employ intra-osseous pins through a separate incision to secure reference arrays to the iliac crest. This study is the first to investigate the consequences of pin use in THA in vivo. METHODS: A prospective, consecutive series of 43 patients presenting for navigated THA were included. Two temporary 125 × 4 mm Schanz screws were inserted into the iliac crest for the attachment of a reference array. Telephone follow-up occurred at 6 and 12 weeks post-operatively...

We report two patients with increased central skull base and craniocervical junction bone pneumatisation complicated by extra-osseous gas. One patient presented with symptoms of increasing nasal blockage and 'sinus pressure' on a background of extensive nasal polyposis. He was subsequently found to have a history of repeated Valsalva's manoeuvre, the cessation of which resulted in a rapid decrease in the amount of extra-osseous gas on imaging. The second patient presented following a minor head trauma with dysarthria from a hypoglossal nerve palsy and neck pain, with extensive intra- and extra-cranial gas including within the spinal canal (pneumorrhachis)...

CASE: The medial collateral ligament (MCL) is the most commonly injured ligament of the knee; however, to our knowledge, avulsion fractures of the MCL resulting in an intra-articular fragment have not been reported. We present the case of a 55-year-old woman with a posterior cruciate ligament avulsion fracture and an MCL avulsion fracture with an intra-articular bony fragment. CONCLUSION: Patients who sustain trauma to the knee should be carefully evaluated for ligamentous avulsion injuries...

Osteosarcoma, the most common malignant primary bone tumor, is currently treated with chemotherapy and surgery. The effectiveness of chemotherapy is evaluated by means of histological analysis of tumor necrosis, known as "the Huvos score". However, 25% of the patients initially considered good responders will relapse. In our practice, strong tissue heterogeneity around the residual viable cells of the osteosarcoma is observed, but this is not taken into account by the Huvos score, as it is only an average...
