Randomized Controlled Trial Comparative StudyInterscalene brachial plexus block for open-shoulder surgery: a randomized, double-blind, placebo-controlled trial between single-shot anesthesia and patient-controlled catheter system.
Interscalene brachial plexus block (ISB) is widely used as an adjuvant regional pain therapy in patients undergoing major shoulder surgery and has proved its effectiveness on postoperative pain reduction and opioid-sparing effect. ⋯ Based on our results, we recommend the use of interscalene plexus block in combination with a patient-controlled catheter system under ultrasound guidance only for the first 24 h after major open-shoulder surgery.

Randomized Controlled TrialIntracorporeal pneumatic shock application for the treatment of chronic plantar fasciitis: a randomized, double blind prospective clinical trial.
Plantar fasciitis (PF) is a common clinical condition that usually resolves with non-operative treatments. Extracorporeal shock wave therapy (ESWT) has been used in the treatment of chronic PF not responding to other conservative measures; however, ESWT devices are expensive and available for daily practice in only few centers (In developing countries). A pneumatic lithotripter is a cheap and readily available device which uses pneumatic shock application for the intracorporeal lithotripsy. The aim of this study was to investigate the clinical efficacy of intracorporeal pneumatic shock therapy (IPST) application for the treatment of chronic PF using a cheap and readily available pneumatic lithotripter. ⋯ This pilot study showed that IPST is an effective and safe method of treatment of patients with chronic PF not responding to conservative measures. IPST application should be considered before surgical intervention when the extracorporeal shock devices are not available for daily practice. However, further evaluation of this novel treatment is necessary to understand the exact mechanism of action.

Clinical TrialAnterior-inferior plating of middle-third fractures of the clavicle.
Various techniques have been reported for the treatment of middle-third clavicle (collar bone) fractures. This prospective study was conducted to evaluate the results of anterior-inferior plating using a 3.5-mm reconstruction plate for the treatment of middle-third clavicle fractures. ⋯ Anterior-inferior plating is an effective treatment modality for middle-third clavicle fractures, with few complications and early return of shoulder function. The procedure provides stable fixation, avoids risk to vital structures below the clavicle, and is associated with a low rate of implant-prominence problems.

Comparative StudyChanges in content and synthesis of collagen types and proteoglycans in osteoarthritis of the knee joint and comparison of quantitative analysis with Photoshop-based image analysis.
The different cartilage layers vary in synthesis of proteoglycan and of the distinct types of collagen with the predominant collagen Type II with its associated collagens, e.g. types IX and XI, produced by normal chondrocytes. It was demonstrated that proteoglycan decreases in degenerative tissue and a switch from collagen type II to type I occurs. The aim of this study was to evaluate the correlation of real-time (RT)-PCR and Photoshop-based image analysis in detecting such lesions and find new aspects about their distribution. ⋯ Photoshop-based image analysis might become a valuable supplement for well known histopathological grading systems of lesioned articular cartilage.

Comparative StudyBiomechanical evaluation of fixation of comminuted olecranon fractures: one-third tubular versus locking compression plating.
New concepts in plate fixation have led to an evolution in plate design for olecranon fractures. The purpose of this study was to compare the stiffness and strength of locking compression plate (LCP) fixation to one-third tubular plate fixation in a cadaveric comminuted olecranon fracture model with a standardised osteotomy. ⋯ Contoured LCP and intramedullary screw fixation can be used as an alternative treatment method for comminuted olecranon fractures as its stiffness and strength were not significantly different from a conventional plating technique.
