OBJECTIVETo investigate clinical curative effects of gluteal muscle contracture release combined with insertion of gluteus maximus tendo-chilles lengthening with Z-shaped in treating severe gluteal muscles contracture.

METHODSFrom 2006 May to 2011 May, 20 patients (35 sides) with severe gluteal muscle contracture were collected, including 12 males and 8 females, aged from 8 to 34 years old with an average of 13 years old; the courses of disease ranged from 3 to 21 years. All patients manifested abnormal gait at different degree, knees close together cannot squat,positive syndrome of Ober, positive test of alice leg. Gluteus contracture fascia release were performed firstly in operation, then insertion of tendo-chilles lengthening with Z-shaped were carried out. Preoperative and postoperative gait, and knee flexion hip extensor squat test, cross leg test, adduction and internal rotary activity of hip joint, stretch strength and motor ability after hip abduction were observed and compared.

RESULTSTwenty patients were followed up for 1 to 5 years. Gluteus maximus were released thoroughly, and snapping hip was disappeared, Ober syndrome were negative. There was significant differences in knee flexion hip extensor squat test, adduction and internal rotary activity of hip joint,stretch before and after operation (P<0.01). Gluteus muscle strength was protected,stretch strength and motor ability of hip joint were recovered well. Among them,31 cases got excellent results and 4 good.

CONCLUSIONFor severe gluteal muscles contracture,insertion of gluteus maximus tendo-chilles lengthening with Z-shaped performed after gluteus contracture fascia release could release gluteal muscle contracture to the greatest extent and obtain postoperative curative effect without resection of normal hip muscle fibers and destroy joint capsule.

Objective To investigate the clinical value of the intervertebral disc morphous in patients with thoracolumbar vertebral compression fracture. Methods The MRI, X-ray and CT data of 75 patients with thoracolumbar vertebral compression fracture were retrospectively analyzed. The intervertebral disc damage degree was observed, and its correlation with vertebral fracture degree and endplate damage degree was studied. The vertebral body leading edge height, intervertebral space height and back convex Cobb angle in patients with different intervertebral disc damage degree were measured. Results The intervertebral disc damage degree height was positively correlated with endplate damage degree (P<0.01), and the intervertebral disc damage degree was positively correlated with fracture degree (P<0.01). With the increase of the intervertebral disc damage degree in patients with Ⅰ - Ⅳtype intervertebral disc damage, the vertebral body leading edge height and intervertebral space height gradually became smaller: (0.68 ± 0.05), (0.61 ± 0.03), (0.58 ± 0.03), (0.42 ± 0.05) mm, and (0.31 ± 0.06), (0.29 ± 0.03), (0.24 ± 0.06), (0.22 ± 0.02) mm, and there were statistical differences (P<0.05). There was no statistical difference in back convex Cobb angle in patients with different intervertebral disc damage degree (P>0.05). Conclusions It is more important to observe the morphological changes of the intervertebral disc in patients with thoracolumbar vertebral compression fracture, and the damage degree is closely related with the vertebral fracture degree and endplate damage degree.

Objective To investigate the clinical characteristic, surgical stage, operative approach, resection and stability reconstruction of dumbbell intra-extradural tumor of cervical spine. Methods From January 1999 to December 2005, 37 consecutive cases with cervical dumbbell intra-extradural tumor were retrospectively studied. 18 males and 19 females ranged from 18 to 80 years old were involved in this study, including 25 schwannomas, 3 neurofibromas, 5 multi-neurofibromas and 4 malignant schwannomas. According to tumor location and involved range, all tumors were divided into five stages: 8 cases in Ⅰ stage, 9 cases in Ⅱstage, 13 cases in Ⅲ stage, 5 cases in Ⅳ stage and 2 cases in Ⅴ stage. Resection and reconstruction were performed at 20 patients through posterior-lateral approach, 17 patients through anterior-lateral combined with posterior-lateral approach. Lateral mass screw internal fixation system were used in 26 cases, while anterior combined posterior fixation were performed in 5 cases and none fixation in 6 cases. Results The follow-up period was from 3 months to 7 years. 1 case developed a transient weakening of upper limb, 1 case developed anesthesia in posterior neck, and 1 case developed Horner's sign. Vertebral artery ligation was performed in 1 case because of vertebral artery injury. 2 cases with malignant schwannoma occurred local recurrence in 1-2 years postoperation and received second operation. The recent effects after operation were satisfactory in majority cases,with complete recovery of spinal cord function in 19 cases. 2 cases without fixation appeared recuration deformity in cervical spine in 1-2 years postoperation. Conclusion The surgical approach and operative methods must be selected according to the location, surgical staging, characters of tumors. Stability reconstruction plays important roles in maintaining stability of cervical spine. More care should be taken in procedure for protecting vertebral artery, cervical nerve and spinal cord.

Objective To develop a new method for the determination of trace manganese in water by flame atomic absorption after cloud point extraction. Methods The effect of experimental conditions such as pH value and concentration of reagents and equilibration temperature on cloud point extraction and determination sensitivity was discussed. The chemical variables affecting the separation phase and extraction recovery were optimized. Results Under the optimum conditions, pre-concentration of only 50 ml of sample in the presence of 0.05% Triton X-114 presented a detection limit of 0.28 ?g/L(3?) for manganese. The enhancement factor was 65 for manganese. The relative standard deviation was 2.17%. The calibration graph using the pre-concentration system for manganese was linear with a correlation coefficient of 0.999 at levels near the detection limits up to at least 120 ?g/L. The recovery rates were 98.0%-101.5%. Conclusion The method is rapid, accurate, simple and is suitable for determination of trace manganese in water samples.
