3D navigation assisted percutaneous vertebroplasty combined with postoperative lower-back muscles training in treatment of osteoporotic vertebral compression fracture / 中国介入影像与治疗学

Objective: To observe value of 3D navigation assisted percutaneous vertebroplasty (PVP) combined with postoperative lower-back muscles training in treatment of osteoporotic vertebral compression fracture (OVCF). Methods: Twenty-five consecutive patients with OVCF were enrolled in observation group and treated with 3D navigation assisted PVP using O-arm scanner and postoperatively systematic back muscle exercise, while other 25 OVCF patients in control group were treated with traditional C-arm assisted PVP and postoperatively regular back muscle exercise. Intraoperative fluoroscopy time, mean dose of radiation, mean procedure time, visual analogue score (VAS) before and 2 h, 1 month, 3 months, 6 months after operation were compared between the two groups. Technical success rate was calculated, and vertebral leakages and complications were observed. Results: Technical success rate of the two groups were both 100% (25/25). The duration of fluoroscopy and operation were shorter, the radiation dose was lower in observation group (all P0.05). Conclusion: PVP guided with 3D navigation combined with postoperative lumbar and dorsal muscle training can safely and effectively treat OVCF, shorten the operation time, reduce radiation exposure and improve the medium and long-term pain symptoms after PVP.

Evaluation of the Back Muscle Exercise for the Lumbar Discectomy Patients

STUDY DESIGN: Retrospective study. OBJECTIVES: To identify the implementation of self-exercise therapy and analyze the effects of exercise therapy after lumbar discectomy. MATERIALS AND METHODS: Studied 47 patients who underwent partial lumbar discectomy and laminectomy from January, 2009 to December, 2009. They were instructed on 16 kinds of exercise therapy in total from postoperative 1day to postoperative 6weeks. Group A (n=25), whose frequency of outpatient clinic visit is above the average, and Group B (n=22), whose frequency of visit is relatively low;, below 5 times. We tested the visual analog scale (VAS scale) of back, Oswestry disability index and the strength of the two groups before surgery and at postoperative 3, 6, and 12 months. RESULTS: The degree of pain was significantly different (26.6+/-9.4 and 53.5+/-18.6) between group A and group B at postoperative 6 months. Function of daily life and strength test were significantly different (6.6+/-4.8 and 11.3+/-4.0 at group A, 3.6+/-0.9 and 3.0+/-1.1 at group B) between the two groups at postoperative 12 months. The characteristics of low compliance patients are low accessibility to the hospital and lack of knowledge on the importance of exercise according to the degree of pain. CONCLUSION: These results suggested that postoperative exercise program has significant effects on the pain, the function of daily life. It also increases flexibility and strengthens the muscle of patients with high compliance of outpatient clinic visit. The factors influencing the results are the age of patients, the willingness to exercise, and the environment in which each patient lives/resides.

Application of the cervical back muscle trainer in the cervical back muscle exercise / 中国康复理论与实践

@#ObjectiveTo investigate the effect of a cervical back muscle trainer. MethodsA cervical back muscle trainer designed by ourself was used in 128 patients with different kinds of cervical spondylosis. The situation of pain and activity of daily life of the patients before and 1 month after treatment were recorded and compared. ResultsThe neck pain of all of the patients nearly completely disappeared in a month and their activity of daily life improved significantly(P<0.01). ConclusionThe cervical back muscle trainer can improve the stability of cervical vertebrae through increasing the strength of the cervical back muscle, which can be used as an assistant rehabilitation approach of all kinds of cervical spondylosis.
