BACKGROUND A new classification system for juxta-articular osteosarcoma around the knee joint was developed to allow biological reconstructions using distraction osteogenesis or frozen autograft containing tumors treated with liquid nitrogen. Type I: Tumor has metaphyseal extension to a maximum of 2 cm from the epiphyseal cartilage plate. Type II: Tumor extends to at least half the circumferenc...

BACKGROUND The sacroiliac joint (SIJ) is a frequently underestimated cause of lower back (LBP). A simple clinical test of sufficient validity would be desirable. The aim of this study was to evaluate the diagnostic value of a new PSIS distraction test for the clinical detection of SIJ arthropathy and to compare it to several commonly used clinical tests. METHODS Consecutive patients, where a ...

Aim to study the effectiveness of combined treatment contractures proximal interphalangeal joint.
 Material and methods. The included 30 patients with a diagnosis post-traumatic mixed contracture joint. were divided into 3 groups. In first group, administered treatment, including arthrolysis joint, imposition dynamic distraction apparatus, injection hyaluronic acid preparations platelet-ri...

Ankle distraction is an alternative to ankle arthrodesis or total ankle arthroplasty in younger patients with arthritis. Ankle distraction involves the use of external fixation to mechanically unload the ankle joint, which allows for stable, congruent range of motion in the setting of decreased mechanical loading, potentially promoting cartilage repair. Adjunct surgical procedures are frequentl...

We report the case of a 57-year-old woman who had basilar impression manifesting as severe myelopathy and occipital neuralgia and was treated by distraction and fixation performed using a modification of Goel's method. Magnetic resonance imaging (MRI) and computed tomography (CT) scans showed severe myelocompression by the dens of the axis from the ventral side and occipitalization of the atlas...

The Ilizarov technique lends itself well to correction of foot deformities because of the three-dimensional nature of the foot and of the apparatus. The two approaches to the correction of foot deformities are (1) soft tissue distraction of the deformity and (2) distraction of an osteotomy. In the former, the deformity is corrected by eliminating pre-existing contractures and by distracting acr...

conclusions callus distraction is an effective and reliable method for lengthening short phalangeal, metacarpal, and metatarsal bones. it also preserves periosteal tissue. our distractor is reliable, cheap, lightweight, user friendly, and highly effective for callotasis. background this study was performed to evaluate the results of finger lengthening following traumatic amputation or congenita...

BACKGROUND Previous designs of internal bone lengthening devices have been fraught with imprecise distraction, resulting in nerve injuries, joint contractures, nonunions, and other complications. Recently, a magnet-operated PRECICE nail (Ellipse Technologies, Inc, Irvine, CA, USA) was approved by the FDA; however, its clinical efficacy is unknown. QUESTIONS/PURPOSES We evaluated this nail in ...

BACKGROUND Ankle distraction arthroplasty is one option for the treatment of severe ankle arthritis in young patients. The outcomes and factors predicting success in distraction arthroplasty are poorly understood. METHODS From January 2011 to May 2015, 16 patients who had undergone ankle distraction arthroplasty for ankle arthritis were operated, including six males and ten females. All patie...

Under the effective chemotherapy protocol, physeal distraction could be used as an effective limb salvage in the growing children with lower-limb malignant metaphyseal bone tumours and could actively prevent leg length discrepancy or malalignment that profoundly affects function. In this paper, we report a 7-year-old boy with right distal tibial osteosarcoma but not yet invaded the epiphysis, w...
