ABSTRACT

OBJECTIVE@#To compare the clinical effecty of Wiltse approach combined with contralateral transforaminal lumbar interbody fusion (TLIF) and traditional TLIF in the treatment of lumbar disc herniation and its affect on injury of multifidus muscle.@*METHODS@#From June 2014 to September 2017, 90 patients with lumbar disc herniation combined with lumbar spine instability were divided into two groups (Wiltse approach group and traditional group) depend on the procedure of operation. Wiltse approach group was treated with Wiltse approach screw placement in one side combined with contralateral TLIF. There were 50 patients in Wiltse approach group, including 36 males and 14 females, aged 45 to 72 yearswith an average of (60.4± 3.1) years. The traditional group was treated with traditional TLIF operation. There were 40 patients in the traditional group, including 25 males and 15 females, aged 45 to 74 years with an average of (62.1±3.4) years. The operative time, intraoperative blood loss, accuracy of screw implantation, postoperative drainage volume and drainage tube removal time were recorded in two groups. Visual analogue scale (VAS) and Oswestry Disability Index (ODI)were observed before and 12 months after operation. All patients underwent CT examination preoperative and 12 months postoperative, and the CT values of bilateral multifidus muscle were measured.@*RESULTS@#All the patients were followed up, 40 patients in traditional group were 12 to 18 months with an average of (15.3±4.3) months; and 50 patients in Wiltse approach group were 13 to 24 months with an average of (16.5± 4.1) months. There were no statistically significant differences in operative time and intraoperative blood loss between two groups (@*CONCLUSION@#Compared with traditional surgical procedures, the Wiltse approach nail placement combined with contralateral TLIF has the advantage of accurate nail placement, reducing multifidus muscle damage, and reducing the incidence of postoperative intractable low back pain.

ABSTRACT

OBJECTIVE@#To analyze the clinical efficacy of unilateral and bilateral intervertebral space release in the treatment of lower lumbar spondylolisthesis.@*METHODS@#The clinical data of 41 patients with lumbar spondylolisthesis treated by surgery from October 2012 and May 2016 were retrospcetive analyzed. The patients were divided into two groups, 18 cases were enrolled in unilateral intervertebral release group, there were 7 males and 11 females, aged from 47 to 75 years old with an average of (59.3±6.4) years; according to Meyerding classification, 9 cases of I degree, 7 cases of II degree, 2 cases of III degree. And 23 cases were bilateral release group, there were 11 males and 12 females, aged from 51 to 76 years old with an average of (58.2±5.7) years; according to Meyerding classification, 11 cases of I degree, 10 cases of II degree, 2 cases of III degree. The operation time, intraoperative blood loss, bone graft fusion rate of the patients were recorded in the patients. Pre- and post-operative back and leg pain were evaluated by visual analogue scale (VAS) between two groups. The slip rate, slip angle, posterior height of intervertebral space, height of intervertebral foramen, distance of anterior and posterior displacement of vertex of intervertebral foramen were measured on X-ray and CT. And the above radiographic data were analyzed by intra-group or inter-group.@*RESULTS@#All the patients were followed up from 9 to 24 months with an average of 12 months. The entire 41 patient obtained bone fusion at 12 months after operation. There was no statistical significance in VAS at 12 months after operation, intraoperative blood loss and operation time between two groups(>0.05). There were statistical significance in sliding angle, posterior height of intervertebral space, height of intervertebral foramen, distance of anterior and posterior displacement of vertex of intervertebral foramen of all patients before and after operation(0.05), but there was significant difference in bilateral release group. There was statistical significance in postoperative slip angle, posterior height of intervertebral space, distance of anterior and posterior displacement of vertex of intervertebral foramen between two groups(=0.001, 0.045, 0.001). The height of intervertebral foramen increased and the slippage rate decreased in both groups after operation, but there was no significant difference between two groups(=0.248).@*CONCLUSIONS@#Unilateral and bilateral intervertebral space release for the treatment of lumbar spondylolisthesis can obviously reduce the rate of spondylolisthesis, restore foraminal height and achieve better clinical efficacy. Bilateral release group can better restore the slip angle, increase posterior height of intervertebral space, reduce the distance of anterior and posterior displacement of vertex of intervertebral foramen. Especially for grade II or above degree of slippage is more appropriate.

ABSTRACT

<p><b>OBJECTIVE</b>To explore efficacy of posterior reduction and interbody fusion in treating thoracolumbar fractures and dislocations.</p><p><b>METHODS</b>From August 2004 to May 2009, 24 patients (18 males and 6 females with an average of 38.2 years, ranged 24 to 56 years old) were treated. Among them, 14 cases were by traffic accident,6 cases were falling down, 2 cases were heavy hit, 2 cases were transverse crush. According to AO classification, 12 cases were type B1, 5 cases B2, 2 cases B3,3 cases C1, 2 cases C2. One cases in T(10,11), 2 cases in T(11,12), 5 cases in T12L1, 8 cases in L(1,2), 2 cases in L(2,3), 4 cases in L(3,4), 2 cases in L4/5. Acoording to Frankle classification,5 cases in grade A, 9 cases in grade B, 8 cases in grade C and 2 cases in grade D. The reduction, graft healing and recovery of nervous function were followed up.</p><p><b>RESULTS</b>All patients were followed up from 8 to 33 months with an average of 16 months. The operation time was for 3.0 to 5.8 hours, meaned 3.7 h, and mean blood loss was 860 ml (ranged, 500 to 1800 ml). Cobb angle improved from preoperative (32.6 +/- 3.7) degrees to postoperative (13.7 +/- 2.4) degrees. The anterior high of fractured vertebrae increased from preoperative (41.0 +/- 11.6)% to postoperative (87.6 +/- 2.3)% .Three cases of 5 cases with Frankle A were not recovery, 1 case changed to grade B, 1 case changed to grade C; Five cases of 9 cases with Frankle B were changed to grade C, 3 cases to grade D, 1 case changed to grade E; Five cases of 8 cases with Frankle C were changed to Grade D, 3 cases to Grade E; Two cases with Frankle D were recoved to normal. Planting bone surface got bone fusion, and no internal fixation lossen, dislocation occurred.</p><p><b>CONCLUSION</b>Posterior reduction and rigid interbody fusion for the treatment of thoracolumbar fractures and dislocations can receive satisfactory fusion based on recovering normal spinal sequence</p>

ABSTRACT

<p><b>OBJECTIVE</b>To explore the feasibility of C1-2 pedicle screw fixation and fusion technique in treating atlantoaxial instability.</p><p><b>METHODS</b>From January 2006 to January 2009,18 patients with atlantoaxial instability were treated with C1-2 pedicle screws and plates fixation under general anesthesia. There were 11 males and 7 females, the age for 17-62 years with the mean of 37.7 years. The course of disease was from 3 days to 30 months with an average of 10.6 months. The patients had different degrees neck pain and disturbance of sensation or (and) dyskinesia, had atlantoaxial instability from images before operation. The JOA scoring before operation were from 8 to 15 with an average of 11.4. Bone fusion of patients was observed with X-rays, CT and MR image at the same time after operation and the JOA scoring was compared with preoperative.</p><p><b>RESULTS</b>A total of 72 screws were successfully placed in 18 cases, among them, 15 cases were followed up from 6 to 24 months with an average of 11.5 months. Fifteen cases obtained bone fusion with time for 3-6 months without the complications of internal fixation failure or redislocation of atlas. The spinal compression had differently improved, postoperative JOA scoring was from 12 to 17 scores with an average of 14.5 scores.</p><p><b>CONCLUSION</b>Pedicle screw fixation and fusion in atlas has advantages of firm fixation and high fusion rate, it is a better choices for atlantoaxial instability. It is not suitable for variations of sulcus of vertebral artery of atlas and posterior arch of atlas.</p>
