ABSTRACT
Objective To investigate the effect and nursing experience of iliacus groin approaches and internal fixation treatment for patients with pelvic fractures. Methods Twenty- six patients with unstable pelvic fracture were obtained iliac groin approaches and internal fixation treatment, the changing symptoms in patients were monitored frequently, and all patients were performed general nursing. Results All patients were followed up for 0.5 to 5.0 years, without obvious complications, the results of surgical treatment included optimal 16 cases, good 7 cases, mean 3 cases. Conclusions Iliacus groin approaches and internal fixation with reconstruction plate treatment on pelvic fractures was proved to be reset accurate, reliable and strong, with better effects. Effective nursing measures can save life of patients with pelvic fractures, speed up rehabilitation of physiological function, improve life quality of the patients.
ABSTRACT
Objective To investigate the ability of auto-dermis grafts in the prevention of epidural fibrosis and adhesions, and provide reference for clinical application. Methods Five Tibet mini-pigs were used and laminectomy was performed in lumbar 2 and 4 segment. Dura was exposed and covered with auto-genous dermis grafts in lumbar 2 (the experimental group), without grafts in lumbar 4 (the autogeoous blank group). The specimens were observed grossly and histologically at 2, 4, 6, 8 and 10 weeks postoperatively. Epidural scar amount and adhere range was evaluated by modified Robertson scoring method and analyzed by SPSS 13.0. No sear and adhesion, 0 point; small amount scar and light-range adhesion, 1 point; medium sear and midrange adhesion, 2 pionts; bulk scar ang high-range adhesion, 3 pionts. Results All grafted dermis survived and thicken obviously than dermis in body surface (P< 0.05). Hair growth, sebaceous gland cyst and sweat cystogenesis were not observed. A larvaceous dissection abruption plane, little cicatricial tis-sue and adhesions rarefaction between dermis and dura were observed in the experimental group. Massive ei-catricial tissue from erector spinae filled in cavitas epiduralis was observed and dura was separated difficult-ly from cicatricial tissue in the autogeous blank group. Epidural scar amount and adhesion range in the ex-perimental group was significantly lower than the blank group (P< 0.05). Conclusion Dermis is a kind of favourable biomaterial with restraining cicatrisation and isolation barrier. Autogenous dermis grafts has the best effect on preventing peridural cicatrisation and adhesion after laminectomy.
ABSTRACT
Physical continuity of bone is damaged following bone defects. The use of exogenous bone morphogenetic protein (BMP) treatment depends on appropriate carrier, which releases exogenous BMP and other growth factor into the bone defect site, inducing new bone formation and achieving therapeutic purposes. There are many carrier materials for BMP, including inorganic material, synthetic polymers, biological material, and composites of these three materials. But all have some deficiencies. So many researchers have optimized them by combined, physical and chemical methods to improve the bone inductive activity. BMP, which is released from carrier or local gene, can repair bone defect effectively, affording a new way for bone defect repairing.
ABSTRACT
Objective To study the early diagnosis and treatment of cervical vertebrae injury.Methods 86 cases with cervial vertebrae injury were retrospectively analyzed.8 cases were treated by head halter treaction,78 cases were treated by skull traction,15 cases treated in early-day operation,27 cases seclected-day operation.Results According to frankel grading.A degree was 36 cases,no betterment,one case died;B degree 18 cases,2 cases improved to C degree,3 cases improved to D degree,13 cases had no improverment;9 cases,all had one or two degree improvement.20 cases with the nerve root injury all had determinate improverment or were cured.Conclusion Quick and correct early diagnosis and treatment after cervical vertebrae injury are the key steps in decreasing the death rate and disability rate.
