Objective To evaluate the midterm efficacy of prosthetic disc nucleus ( PDN) replacement for the treatment of lumbar disc herniation. Methods Twenty cases of lumbar disc herniation( including one case of recurrent lumbar disc herniation) were treated with PDN. The twenty cases were followed-up 5.4 ~6.2 years( mean 5.7 years). Functional,and radiographic follow-up examinations,MRI and follow-up records of all patients were reviewed carefully. Results Clinical evaluation at the end of follow-up,there were 10 cases in excellent,6 cases in good,2 cases in fair and 2 cases in poor,and good rate was 80%. One patient accepted the revision operation to remove the PDN because of device migration. One patient accepted the fusion because of adjacent segment disease. The others experienced pain relief, and resumed their normal life and work. The average Oswestry score and VAS get better significantly. Conclusion The PDN was effective in treating patients with lumbar disc herniation. However, the medium term complications of device subsidence should be taken seriously.

Objective To investigate clinical features and anterior surgical results of cervical myelopathy in patients more than 70 years of age. Methods Twenty aged patients with cervical myelopathy who underwent anterior decompression with bone graft surgery were reviewed. Neurological function was assessed using a scoring system proposed by the Japanese Orthopaedic Association (JOA score). The clinical results and complications were compared with the control group which included 31 patients with multisegmental cervical myelopathy and less than 69 years old and underwent the same operation. Results The preoperative mean JOA score was 9.3 (ranged from 3 to 14) and the JOA score at latest follow-up averaged 13.4 (ranged from 8 to 17) in the aged patient group. 68 percent patients had achieved an excellent or good result and the recovery rate was 58%. 71 percent patients had achieved an excellent or good result and the recovery rate was 67% in the control group. No statistical difference was found in the excellent and good result rate or the recovery rate of JOA score between the aged group and the control group (?字2=0.04, P=0.85;t=1.12, P=0.138). The incidence of surgical related complications in the aged group was 35% (7 cases), which was considerably higher than that in the control group (3 cases, 10%) but without statistical difference (?字2=3.47, P=0.06). In the preoperative flexion-extension stress lateral radiographs, the incidence of cervical instability was higher in the control group (8 cases, 26%) than that in the aged group(1 case, 5%). Conclusion 1) Multilevel lesion induced by overcompensation for cervical instability are the probable cause of myelopathy in aged patients. 2) Anterior decompression is beneficial to improve the neurological function and life style in the aged patients with cervical myelopathy, but associated with a high incidence of surgical complications.

Objective To evaluate the surgical strategy of decompression via posterior-anterior approach and anterior fixation in treatment fracture-dislocation of the lower cervical spine with bilateral facet joints dislocation. Methods This study retrospectively reviewed 37 cases of lower cervical spine fracture with bilateral joints dislocation. There were 21 males and 16 females with an average age of 42 years (19-58). Distraction-flexion stage 3(DFS 3) were found in 24 cases and DFS 4 in 13 cases. All the cases were diagnosed by X-ray, CT and MRI and confirmed during the surgery. Decompression via posterior-anterior approach and anterior fixation had been adapted as the surgical strategy. The NASCIS and IMSOP standard were applied to definite the level of cervical spinal cord injury. The ASIA grading was used for evaluation the spinal cord function and the recovery rate. The X-ray and CT were used to observe reduction and bone fusion. Results The mean operative time was (4.5:±0.5) h, and the mean amount of blood loss was 360 ml (200-500 ml). All the incision healed. The two segments fixation was used in 23 cases, 3 segments fixation in 13 cases, and 4 segments fixation in 1 case. The mean follow-up period was 32 months (16-45 months).Postoperative X-ray and CT showed that bone fusion was achieved in all patients within 4-8 months, without graft displacement, or failure of implants. Spinal cord function did not aggravate, and sensory recovery ranged from 7 to 20 levels (averaged, 12.7). The ASIA grade were improved with an average of one grade. Conclusion To treat fracture-dislocation of the lower cervical spine with bilateral facet joints dislocation, the posterlor-anterior approach and anterior fixation/fusion was benefit to preservation the cervical spinal cord function and reconstruction biomechanical stability of the cervical spine.

Objective:To compare the outcomes of arthroscopic rotator cuff repair in patients with or without stiffness.Methods:Retrospective analysis was performed on the data of 20 patients (stiffness group) who underwent arthroscopic rotator cuff repair combined with capsular release from January 2017 to November 2019. There are 9 males and 11 females, age 62.2±8.7 years old (range 45 to 80 years old), preoperative duration 5.2±4.3 months (range 1 to 12 months). 54 patients who underwent arthroscopic rotator cuff repair without stiffness were used as the control group. There were 16 males and 38 females, aged 60.9±9.1 years old (range 46 to 81 years old), preoperative duration 8.2±13.0 months (range 1 to 60 months). Pain, function and range of motion (ROM) were recorded at 1 month, 3 months, 6 months post-operatively and last follow-up, and compared with that of pre-operatively. Satisfaction and complication were recorded at the last follow-up. The main outcome measurements included the visual analogue scale (VAS), the American Shoulder and Elbow Surgeons (ASES) score, the University of California at Los Angeles shoulder rating scale (UCLA), Constant-Murley score, and range of motion.Results:The mean follow-up period was 19.7±4.6 months (12-30 months) in the stiffness group, and 18.6±4.4 months (12-29 months) in non-stiffness group. VAS, ASES score, UCLA score, Constant-Murley score and ROM were significantly improved post-operatively. One month post-operatively, the VAS score was 4.2±1.5 in stiffness group, and 3.4±1.1 in the non-stiff group, and the difference was statistically significant between two groups ( t=2.381, P=0.020). There was no significant difference at 3 months post-operatively. The ASES score, UCLA score and Constant-Murley score were 52.3±10.2, 17.8±4.2 and 51.7±9.7 in stiffness group at 3 months post-operatively, and 57.4±7.4, 21.6±3.8, 63.2±13.5 in non-stiffness group, respectively. The difference was statistically significant ( t=2.363, P=0.021; t=3.713, P<0.001; t=3.484, P<0.001). There was no significant difference at 6 months post-operatively. The postoperative satisfaction of stiffness group and the non-stiffness group were 95.0% and 96.3%, respectively. The difference was not statistically significant ( χ2=0.2511, P=0.802). Conclusion:The results of stiffness group are statistically the same as those in non-stiffness group at last follow-up, although the recovery period is longer in patients who combined with stiffness at the first 6 months.

AIM To investigate the effect of frozen recombinant staphylokinase on the hemostatic and fibrinolytic systems in healthy volunteers, in order to obtain reliable evidence for the possibility of further clinical application. METHOD r-Sak had been taken intravenously by 20 cases of healthy volunteers in different dosages (1 mg, 2.5 mg, 5 mg, 10 mg, 15 mg). The clinical hemorrhagic manifestations were observed and a set of hemostatic tests(BT, BPC, ATPP, PT, TT, Fg) and fibrinolytic tests (PL∶A,α2-PI∶A, FDP, D-D) monitored before and after injection. RESULT Four of 20 volunteers showed slight hemorrhagic tendency on mucocutaneous area (3/4 from gingivea and 2/4 at the sites of injection). It stopped spontaneously. None of them showed visceral bleeding. There were no significant changes in hemorrhagic and coagulative phases. Only 4 of them showed slight abnormal changes in D-D. It was supported that r-Sak was a highly selective fibrirolytic agent without significant influence in human hemostatic and coagulatic system. CONCLUSION The specific ranges of doseges, r-Sak is a relatively safe and well tolerated agent for healthy people. Further clinical study is still needed for the suitable dosage for clinical application.
