Effect of extracorporeal shock wave treatment on deep partial-thickness burn injury in rats: a pilot study.

Extracorporeal shock wave therapy (ESWT) enhances tissue vascularization and neoangiogenesis. Recent animal studies showed improved soft tissue regeneration using ESWT. In most cases, deep partial-thickness burns require skin grafting; the outcome is often unsatisfactory in function and aesthetic appearance.

Texture analysis, bone mineral density, and cortical thickness of the proximal femur: fracture risk prediction.

Objective: The objectives of this study were to perform a clinical study analyzing bone quality in multidetector computed tomographic images of the femur using bone mineral density (BMD), cortical thickness, and texture algorithms in differentiating osteoporotic fracture and control subjects; to differentiate fracture types.

Methods: Femoral head, trochanteric, intertrochanteric, and upper and lower neck were segmented (fracture, n = 30; control, n = 10). Cortical thickness, BMD, and texture analysis were obtained using co-occurrence matrices, Minkowski dimension, and functional and scaling index method.

Extracorporeal shock wave treatment in ischemic tissues: what is the appropriate number of shock wave impulses?

The dose-dependent effect of extracorporeal shock wave technology (ESWT) was evaluated using a murine skin flap model. Thirty-six Sprague-Dawley rats were divided into six groups (ESWT groups 1 through 5 and a control group). After surgery, shock wave impulses doses were administered: 200 (group 1), 500 (group 2), 1500 (group 3), 2500 (group 4), 5000 (group 5), and 0 (control group 6).

Corrective osteotomy in symptomatic midshaft clavicular malunion using elastic stable intramedullary nails.

Introduction: It is our goal to present an alternative, less invasive surgical technique for corrective osteotomy in symptomatic midshaft clavicular malunion using elastic stable intramedullary nails (ESIN) and to present our results in a consecutive patients series.

Method And Patients: Between January 2003 and December 2006, five patients aged between 23 and 44 years presented with a symptomatic malunion after nonoperative treatment of displaced midshaft clavicular fractures. Corrective osteotomy was performed without bone grafting.

Suspensory fixation of grafts in anterior cruciate ligament reconstruction: a biomechanical comparison of 3 implants.

Purpose: Our purpose was to evaluate the biomechanical difference between 2 new soft-tissue anterior cruciate ligament (ACL) fixation devices (RetroButton [Arthrex, Naples, FL] and ToggleLoc [Biomet, Warsaw, IN]) and a clinically established implant (EndoButton CL; Smith & Nephew, Andover, MA).

Methods: In test session 1 biomechanical testing was performed by use of 48 porcine femora fixed to a material testing machine. In session 2 the implants were tested alone.

Shock wave therapy reduces necrotic flap zones and induces VEGF expression in animal epigastric skin flap model.

The effect of extracorporeal shock wave (ESW) therapy on skin flap survival and growth factor expression was investigated in a rat model using epigastric skin flap. Treatment and control groups each contained 20 animals. ESW effectively enhanced epigastric skin flap survival by significant reduction of areas of necrotic zones.

High-resolution ultrasound of the supraclavicular brachial plexus--can it improve therapeutic decisions in patients with plexus trauma?

Patients with major traumatic brachial plexus lesions benefit from early surgery, but they are seldom isolated by today's diagnostic workup. Subjects with ambiguous findings after such workups usually undergo a trial of conservative treatment and those without improvement delayed surgery. Our study focuses on this problem.

Ultrasound guidance for facet joint injections in the lumbar spine: a computed tomography-controlled feasibility study.

Unlabelled: We conducted this study to develop an ultrasound-guided approach for facet joint injections of the lumbar spine. Five zygapophyseal joints (L1-S1) on each side of 5 embalmed cadavers were examined by ultrasound for a total of 50 examinations. The joint space was demonstrated under ultrasound guidance.

Comparison of the effectiveness of gene therapy with transforming growth factor-beta or extracorporal shock wave therapy to reduce ischemic necrosis in an epigastric skin flap model in rats.

The induction of neoangiogenesis by exogenous growth factors in failing skin flaps has recently yielded promising results. Gene transfer with virus vectors has been introduced as a highly capable route of administration for growth factors, such as vascular endothelial growth factor or fibroblast growth factor. Extracorporal shock waves (ESW) deliver energy by means of high amplitudes of sound to the target tissue and have been shown to induce angiogenesis.

Sciatic nerve enlargement in the Klippel-Trenaunay-Weber syndrome.

The case of a 35-year-old woman with Klippel-Trenaunay-Weber syndrome (KTWS) showing clinical symptoms of a peroneal nerve lesion is presented. An immense nerve enlargement along most of the sciatic, peroneal and tibial nerve was found to be due to a lipoma arising from the epi- and perineurium. Treatment consisted of extensive microsurgical neurolysis and excision of the tumor resulting in decompression of the affected nerves.

Real-time sonographic imaging for periradicular injections in the lumbar spine: a sonographic anatomic study of a new technique.

Objective: We conducted this study to develop a sonographically guided approach to the spinal nerve of the lumbar spine and to assess its feasibility and accuracy by means of computed tomography (CT).

Methods: Fifty sonographically guided approaches at 5 levels (L1-S1) were performed on 5 embalmed cadavers, which were positioned prone. The spinal nerves of the lumbar spine were shown under sonographic guidance.
