Early Functional and Radiological Outcomes Between Plaster Cast and Fiberglass Cast in Stable Thoracolumbar Burst Fracture

Introduction: Burst fracture results from compression failure of both the anterior and middle columns under substantial axial loads. Conservative treatment was a method of treatment for fractures without neurological deficit. This cross sectional study was designed to evaluate the functional and radiological outcome of patient with thoracolumbar burst fracture treated conservatively. Methods: 40 cases were recruited from January 2013 till December 2015. They were followed-up with minimum period of 1 year and evaluated for the functional (Oswetry Disbility Index) and radiological outcomes (kyphotic angle deformity and anterior body compression). Results: 20 patients were treated with body cast made form plaster of Paris and remaining 20 patients with fiberglass cast. In plaster of Paris group, mean kyphotic angle deformity at last follow up was 16.60 ± 2.95 with a mean improvement 4.45 degree and anterior body compression at last follow up was 30.35% ± 10.2 with mean improvement of 9.30%. In fiberglass group, mean kyphotic angle deformity at last follow up was 15.55 ± 3.38 with a mean improvement 7.25 degree and anterior body compression at last follow up was 25.90% ± 7.81 with mean improvement of 3.45%. The functional outcome showed Oswetry Disability Index (ODI) score in plaster of Paris group was 23.70 (SD = 7.82) and in fiberglass group was 18.50 (SD = 5.94). Conclusions: Application of body cast using a fiberglass material give better radiological outcome hence less pain, more functional and higher patient’s satisfaction as compared to plaster of Paris.

Study on Bit Body Materials Made of Tungsten Carbide and Steel Shot

This paper introduces a new kind of diamond bit body material. The characteristics of this material are as follows: the outer bit body cast with tungsten-carbide and the inside is steel shot. So the bit body has got high wear resistance on the outside and good mechanical properties inside at the same time. The mechanical properties inside and the wear resistance outside of the bit were tested. The paper also introduces how to apply a film of mixture of glue-included tungsten-carbide on the surface of the bit mold and graphite stick. The improvements of mechanical properties inside and maintenance of wear resistance outside have made much choice to design wider and deeper junk slots. Thus the performance of bit has been improved.

Treatment of a shoulder luxation in a forelimb amputee dog

SummaryAn eight-year-old, male, thoracic limb amputee Whippet presented with a traumatic lateral luxation of the scapulohumeral joint. Surgical reduction and stabilisation of the shoulder joint by means of a modified Campbell scapulohumeral prosthesis and capsulorrhaphy was unsuccessful and reluxation of the shoulder joint occurred. Subsequent surgical stabilisation using bicipital tendon transposition and a modified Campbell scapulohumeral encircling prosthesis in combination with a novel body cast / Spica splint resulted in a return to satisfactory function of this limb.
