ABSTRACT
A retrospective analysis was performed among 8 patients with unilateral intraarticular calcaneal fracture, who were selected from the Department of Orthopaedics in Yangpu District Central Hospital of Shanghai. They were treated with the injectable bone graft MIIG[R] X3 combined with percutaneous reduction by leverage and axial fixation from June 2005 to November 2006. After treatment, the function of affected feet was evaluated according to the ankle-hindfoot score of the American Orthopaedic Foot & Ankle Society (totally 100 points). All the patients were rechecked with X-ray films periodically to observe the reaction between the materials and the host, the healing of fracture, the pain of limbs and joint motion. Eight patients were all followed up, the complication rate reached 12.5% (1/8), the improvement of Bohler angle excelled 18° to 25°, and that of Gissane angle exceeded 30° to 35°. Among the included patients, 6 cases achieved excellent effect and 2 cases good. All developed the bone union. None of all had complications, such as necrosis of skin, hematoma and deep infection.
ABSTRACT
[Objective]To explore the mechanism of nucleoplasty combined with oxygen-ozone for the treatment of lumbar disc herniation，and to evaluate its therapeutic effects.[Method]From June 2005 to June 2006，62 patients with lumbar disc herniation were treated by nueleoplasty combined with oxygen-ozone，34 were male and 28 were female，ranging in age from 32 to 76 years，with an average of 53.4 years.The course of this disease ranged from 3 to 56 months，meanly 1.3 years.Thirteen patients had the herniation at L4.5 and L3，4，thirty two patients at L4、5，eight patients at L4、5 and L5S1，and nine patients at L5S1.The curative effect was assessed by using a modified MacNab method.[Result]After 25～35 months'follow-up，there were no servious complications in all 62 cases.According to modified MacNab assessment，50 cases(80.7%)achieved excellent outcomes，8 cases(12.9%)good，2 cases(3.2%)fair and 2 cases(3.2%)poor.The excellent and good rate was 93.5%.[Conclusion]The micro-invasive technique of nueleoplasty combined with oxygen-ozone is effective in the treatment of lumbar disc herniation，and it has maximized the clinical effect and minimized the local damage：it also expanded adaptive cases with lumbar disc herniation and enlarged the applicable scope of minimally invasive technique in treating lumbar disc hemiation.
ABSTRACT
Objective To study the factors affecting the functional restoration of the hip joint with femoral intertrochanteric fractures.Method44 patients with femoral intertrochanteric fractures were treated from Aprail 2004 to June 2006.The function of the hip joint was evaluated with the Harris hip score. Seven factors including age,sex,preoperative ASA class,preoperative time,fracture type,therapeutic measures,time of functional exercise were analyzed statistically with x2 test and logistic multiple regression with a significant difference (P
ABSTRACT
Objective To investigate the significance of myelography for selecting operation methods in microendoscopic discectomy(MED).Methods A total of 196 patients with lumbar disc herniation diagnosed by CT/MRI received a myelography before MED.According to their clinical manifestations,signs,and outcomes of myelography,the patients were given three different operation methods.①Simple discectomy was performed in 105 patients with patent spinal canal,lateral impression at intervertebral level,and shift of the nerve root sleeve;②Discectomy with spinal decompression was performed in 70 patients with patent spinal canal and compression of the nerve root sleeve;③Discectomy with semilaminectomy was performed in 21 patients with patent spinal canal,semispherical compression of the nerve root sleeve,and 7-shaped nerve root.Results The operation time was 30~90 min(mean,50 min) and the intraoperative blood loss was 30~120 ml(mean,50 ml).No intraoperative complications occurred.Conversions to open surgery were required in 21 patients,including partial spinal stenosis in 16 patients and thickened vertebral plate in 5 patients.Follow-ups were carried out in 196 patients for 3~58 months(mean,34 months).According to the Japanese Orthopedic Association(JOA) scoring system,the final scores significantly increased postoperatively(25.86?2.96) than preoperatively(13.21?4.96)((t=)38.24,P=0.00).According to the Macnab and Watts standard,the rate of excellent or good results was 93.7%(164/175).Conclusions Myelography has an important reference value for selecting operation methods of microendoscopic discectomy in patients with lumbar disc herniation.
