We investigated the effect of progesterone on the nerve during lengthening of the limb in rats. The sciatic nerves of rats were elongated by leg lengthening for ten days at 3 mm per day. On alternate days between the day after the operation and nerve dissection, the progesterone-treated group received subcutaneous injections of 1 mg progesterone in sesame oil and the control group received oil ...

Ollier's disease is characterised by severe deformity of the extremities and retarded growth because of multiple enchondromas. For correction of deformity, the Ilizarov method has been used although it has many complications. A 17-year-old boy with Ollier's disease had a limb-length discrepancy of 17.4 cm, with a valgus deformity of the right knee and recurvatum of the femur of 23 degrees . He ...

Today's medical technology makes it possible to increase leg length for people with leg length discrepancies or excessively short limbs. With the Ilizarov method bones can be gradually elongated (max. Immlday) without implantation of bone grafts or multiple operations. Although the operative procedure is relatively simple, the negative side effects for the patient are considerable. An external ...

BACKGROUND Coronal imbalance of the pelvis is recognized to lead to the development of degenerative lumbar scoliosis. We hypothesized that an abrupt change of pelvic obliquity may show a reproducible trend of coronal compensation in the lumbosacral spine. The aim of the study was to classify the change of coronal alignment of spine after THA. METHODS This is a retrospective study based on the...

this article presents a new technique for weakening the superior oblique muscle by lengthening it's tendon. lengthening is accomplished by a nasal superior oblique tenotomy, and by inserting a segment of silicone band 240 between the cut ends of the tendon. this technique is useful for the treatment of brown syndrome and cases with superior oblique overaction.

background: surgical crown lengthening is needed for teeth with subgingival caries, fractured teeth, insufficient crown length, and deep subgingival margin of failed restorations. since there is no agreement on the effects of crown lengthening surgery on gingival parameters, the purpose of this study was to evaluate periodontal parameters in patients who needed crown lengthening surgery. method...

introduction: repair of peripheral nerve injuries is an intensive area of challenge and research in modern reconstructive microsurgery. intensive research is being carried out to develop effective alternatives to the standard nerve autografting, avoiding its drawbacks. the aim of the study was to evaluate the effectiveness of a newly designed mechanical device for the reconstruction of the scia...
