To explore efficacy and safety of using denervation of dorsal medial branch to treat the low back pain due to lumbar joint origin. ⋯ It is effective by denervation of dorsal medial branch to treat the low back pain due to lumbar joint origin. There are significant difference in low back pain VAS between every two among the preoperation,single branch blocked group,dual branches blocked group and three branches blocked group. There is no significant difference between four branches blocked group and three branches blocked group. In low back muscle strength and average EMG of multifidus, compared with the preoperation group,there is no significant decline in single branch blocked and dual branches blocked group,and there is significant decline in three branches blocked and four branches blocked group. Therefore, single or dual dorsal medial branch blocked is safety. Among the dual branches blocked group, dorsal medial branches of the involved and the upper level blocked should be given priority to. There is a certain risk in three or four dorsal medial branches blocked which should be used with caution.

To evaluate the efficacy and clinical outcome of reduction and pedicle screws fixation at the fracture level with the approach through para-vertebral muscles in treating thoraeolumbar fractures. ⋯ Using reduction and short-segment pedicle screws fixation at the fracture level through para-vertebral muscles approach is an effective method in treating thoracolumbar fractures. The method has advantages of simple operation,easy establishing screw, short operative time, less blood loss, which can obtain good reduction and stable, reliable fixation after operation.

To evaluate the efficacy and clinical outcome of the treatment of thoracolumbar single compression fracture by using in situ rod rotation reduction and short segment pedicle screw at the fracture level. ⋯ The thoracolumbar single compression fracture can obtain and maintain a good restoration by using the technic of in situ rod rotation reduction and short segment pedicle screw at the fracture level. The technique should be highly recommended.

To introduce the procedure of the 1st ray stabilization combined with resection of the lesser metatarsal heads for patient with severe forefoot deformity caused by rheumatoid arthritis (RA) and evaluate the short to mid-term clinical results. ⋯ The characters of forefoot with RA in later stage are the 1st ray deformity and instability compound with the lesser toes deformity. The 1st ray stability procedure which include the 1st MTP arthrodesis and the Lapidus procedure can correct the 1st ray deformities and rebuilt its stability. The lesser toes metatarsal head resection is effective in correct their deformity. This combined procedure is reliable. It is suitable for patients with severe Hallux valgus, increased IMA, tarsometatarsal joint instability and the lesser MTP joint stiff dislocation.

To evaluate the modified Stoppa approach in treatment of pelvic and acetabular fractures. ⋯ The modified Stoppa approach can be used to treat pelvic and acetabular fractures effectively, and it has advantages of easy manipulation and a low complication rate.
