Abstract BACKGROUND: The study was conducted to determine whether radiofrequency ablation (RFA) can safely reduce pain from osseous metastatic disease. METHODS: single‐arm prospective trial included patients with a single painful bone metastasis unremitting score >50 on scale of 0‐100. Percutaneous computed tomography‐guided RFA the temperatures >60°C performed. Endpoints were toxicity and effects before at 2 weeks, 1 month, 3 months after RFA. RESULTS: Fifty‐five completed Grade...

Background: Popliteal artery injury is frequently associated with knee dislocation following blunt trauma, an that being seen increasing frequency. The primary purpose of the present study was to evaluate use physical examination determine need for arteriography in a large series patients dislocation. secondary correlation between findings and clinically important vascular subgroup who underwent arteriography. Methods: One hundred thirty consecutive (138 knees) had sustained acute...

The purpose of this study was to document the pattern ligament and meniscal injuries that occur during high-energy tibial plateau fractures. One hundred three patients with fractures due mechanisms were evaluated knee magnetic resonance imaging (MRI). All studies read by a single musculoskeletal radiologist who blinded surgical physical exam findings. Pertinent demographic information obtained. There 66 AO/OTA type 41C 37 41B Seventy-three (71%) tore at least one major group, 55 (53%)...

Background: Deep-vein thrombosis following skeletal trauma is an important yet poorly studied issue. The purpose of the present study was to evaluate efficacy two different strategies for prophylaxis against deep-vein and pulmonary embolus blunt trauma. Methods: Two hundred twenty-four inpatients were enrolled in a prospective, randomized investigating venous thromboembolic disease patients completed study, which compared regimens prophylaxis. Group A received enoxaparin (30 mg, administered...

Insulin resistance has been associated with the accumulation of fat within skeletal muscle fibers as intramyocellular lipid (IMCL). Here, we have examined in a cross-sectional study interrelationships among IMCL, insulin sensitivity, and adiposity European Americans (EAs) African (AAs). In 43 EA AA subjects, measured soleus IMCL content proton-magnetic resonance spectroscopy, sensitivity hyperinsulinemic-euglycemic clamp, body composition dual-energy X-ray absorptiometry. The subgroups had...

The use of dynamic ultrasonography (US) in diagnosing traumatic and nontraumatic extensor tendon dislocations fingers three subjects is reported. Dynamic US the clenched fist two patients with injury revealed dislocated but grossly intact tendons surrounded by soft-tissue edema; magnetic resonance (MR) imaging one patient indicated similar findings. Rupture sagittal band hood mechanism was confirmed at surgery. third subject, an asymptomatic volunteer, had a congenital tendency toward...

The hypothesis of this study was that pulsatile mechanical compression superior to standard sequential for decreasing the prevalence deep-vein in patients with or fracture.A prospective, randomized, blinded two methods prophylaxis against conducted. One hundred seven were randomized into either Group A (fifty-four patients), which thigh-calf low-pressure sequential-compression device used, B (fifty-three...

Twelve patients, all over 17 years of age, with adult neuroblastomas, an entity recently described, were seen at Roswell Park Memorial Institute for the period from 1950 to 1977. Four these patients who treated by multimodality therapy constitute bulk this report. One patient had a complete response and showed no evidence desease 23 months after treatment surgery combination chemotherapy (CYVADIC); she also maturation established metastases. Another remained stable 22 chemotherapy. These...

Bone loss secondary to primary or metastatic lesions of the proximal humerus remains a challenging surgical problem. Options include preservation joint with stabilisation using internal fixation resection tumour prosthetic replacement. Resection often includes greater tuberosity and adjacent diaphysis, which may result in poor function rotator cuff and/or deltoid function. Preservation reduce time hospital peri-operative morbidity compared replacement, better functional outcome. We included...
