INTRODUCTION: Unstable intra articular fractures of distal radius are frequently being managed with open reduction and internal fixation. Volar locking plate based on polyetheretherketon (PEEK) polymer has developed lately as an alternative to conventional metallic devices. The advantage of this kind of plates include the lack of metal allergies, radiolucency, low artefacts on MRI or imaging scans and the high resistance associated to loading forces. The aim of this study was to evaluate the clinical and radiological results using a new Carbon-PEEK volar locking plate compared with titanium volar locking plates for the treatment of distal radius fractures...

Small animal studies have demonstrated significant high-dose recombinant parathyroid hormone1-34 (rPTH1-34) effects on intercalary allograft healing. Towards a human adjuvant therapy to decrease non-unions, we evaluated rPTH1-34 safety and efficacy in a clinically relevant canine femoral allograft model. Adult female mongrel hounds (n = 20) received a 5cm mid-diaphyseal osteotomy reconstructed with a plated allograft, and were randomized to: 1) Placebo (n = 5; daily saline), 2) Continuous rPTH1-34 (n = 7; 5 μg/kg/day s...

BACKGROUND: The magnitude of head and neck (H&N) cancers in the Indian subcontinent is very high. Neck nodal involvement is indicative of higher stage and subsequent adverse prognosis when compared with node negative disease. The frequency of such spread is greater than 20% for most H&N squamous cell carcinomas (SCC). The purpose of this study was to analyze the pattern of nodal metastasis in patients presenting with SCC of buccal mucosa (BM) and correlate it with survival. PATIENTS AND METHODS: Ninety-nine cases of carcinoma BM who received post op radiotherapy were analyzed retrospectively...

Osteoporosis-related vertebral compression fractures (OVCFs) are a common and clinically unmet need with increasing prevalence as the world population ages. Animal OVCF models are essential to the preclinical development of translational tissue engineering strategies. While a number of models currently exist, this protocol describes an optimized method for inducing multiple highly reproducible vertebral defects in a single nude rat. A novel longitudinal semiautomated microcomputed tomography (µCT)-based quantitative structural analysis of the vertebral defects is also detailed...

BACKGROUND: In order to improve the correction and fusion rates, an anterior release is often needed for treatment of idiopathic scoliosis with a curve of more than 75° before posterior correction, instrumentation and fusion. However, there are disadvantages to anterior release, and we are concerned about whether it is necessary for anterior/posterior spinal fusion in these patients. PURPOSE: To compare the surgical results for idiopathic scoliosis with curve of more than 75° and flexibility less than 25% between using posterior-only approach and combined anterior release followed by posterior correction with a hybrid construct (hooks and pedicle screws) and spinal fusion...

Background/Purpose: In colon cancer (CC) patients preoperative (pre-op) levels of VEGF-A165 (VEGF) is a strong predictor for disease recurrence. Elevated postoperative (post-op) VEGF levels could have undesirable effects by enhancing tumor growth and metastasis formation. It has been suggested that thromboprophylaxis with a Low Molecular Weight Heparin (LMWH) in surgical cancer patients, further to thromboembolic protection, may exert some anti-neoplastic properties, as well. The aim of our study was to assess the potential impact of the LMWH Tinzaparin (Innohep® - Leo Pharma, Copenhagen, Denmark), given at different doses and for different perioperative (peri-op) periods, upon the post-op variability of serum VEGF levels in surgical CC patients...
