[Effect of Bryan cervical disc replacement on cervical curvature and replacement segment in treating cervical spondylosis].

Objective: To investigate the effect of Bryan cervical disc replacement on cervical curvature and replacement segment in the treatment of cervical spondylosis, and analyze its clinical efficacy.

Methods: Forty-nine patients underwent Bryan artificial cervical disc replacement from August 2010 to August 2013 were retrospectively analyzed. There were 26 males and 23 females, aged from 27 to 66 years old with an average of 48.

Cervical anterior hybrid technique with bi-level Bryan artificial disc replacement and adjacent segment fusion for cervical myelopathy over three consecutive segments.

This study aimed to assess the preliminary clinical efficacy and feasibility of the hybrid technique for multilevel cervical myelopathy. Considering the many shortcomings of traditional treatment methods for multilevel cervical degenerative myelopathy, hybrid surgery (bi-level Bryan artificial disc [Medtronic Sofamor Danek, Memphis, TN, USA] replacement and anterior cervical discectomy and fusion) should be considered. Between March 2006 and November 2012, 108 patients (68 men and 40 women, average age 45years) underwent hybrid surgery.

[Clinical study of a cervical anterior Hybrid technique with posterior longitudinal ligament retained for cervical spondylosis].

Objective: To explore the clinical effects and significances of a cervical anterior Hybrid technique with posterior longitudinal ligament retained in treating cervical spondylosis.

Methods: The clinical data of 138 patients with cervical spondylosis underwent cervical anterior Hybrid surgery were retrospectively analyzed from March 2009 to March 2013. There were 52 males and 86 females,the age ranged from 36 to 58 years old with an average of 45.

Multivariate analysis of risk factors for predicting supplementary posterior instrumentation after anterolateral decompression and instrumentation in treating thoracolumbar burst fractures.

Background: Although anterolateral decompression and instrumentation has several advantages in treating thoracolumbar burst fractures, the risk factors for supplementary posterior instrumentation are still unclear.

Methods: We retrospectively reviewed 238 patients who underwent anterolateral decompression and instrumentation for single-level thoracolumbar burst fractures from January 2010 and March 2012. The influences of several potential risk factors that might affect supplementary posterior instrumentation were assessed using univariate and multivariate analyses.

[Application of exercise therapy on rehabilitation after selective posterior rhizotomy (SPR) in children with cerebral palsy].

Objective: To observe the clinical effect of exercise therapy on rehabilitation after selective posterior rhizotomy (SPR) in children with cerebral palsy, so as to provide reliable rehabilitation method for children with cerebral palsy.

Methods: Two hundred and twenty-six children with cerebral palsy were treated in the study during September 2003 to April 2007. All the patients were randomly divided into the training and control groups.

[Treatment of equinovarus caused by cerebral palsy with neurotomy of muscular branch of tibial nerve].

Objective: To evaluate clinical effect of neurotomy of muscular branch of tibial nerve for the treatment of equinovarus caused by cerebral palsy.

Methods: Fifty-two cases of equinovarus caused by cerebral palsy were treated with neurotomy of muscular branch of tibial nerve. The male was 33 (38 feet) and the female 19 (26 feet) with the average age of 7.
