BACKGROUND: Lumbar spondylolysis is the common cause of teenagers' low back pain. It should apply internal fixation if conservative treatment is invalid. There are a variety of surgeries, which aims to alleviate pain and bony fusion of pars defect.OBJECTIVE: To observe clinical outcome of bone graft of pars defect plus temporary single segmental pedicle screw rod fixation for adolescent lumbar spondylolysis.METHODS: A total of 32 adolescent patients of lumbar spondylolysis were treated by bone graft of pars defect plus temporary single segmental pedicle screw rod fixation. All the patients had bilateral spondylolysis. 20 patients had no lumbar spondylolisthesis, while the others had I° spondylolisthesis. All the patients received lumbar radiograph, CT and MRI. Visual analogue scale and Oswestry disability index were utilized to evaluate pain improvement before and after operation. MacNab was used to assess efficacy. Bone graft healing at isthmus was observed with lumbar CT after fixation. The internal fixation was removed after bone fusion, then the motion of the fixed segment and the degeneration of adjacent intervertebral disc occurred were recorded.RESULTS AND CONCLUSION: (1) Completed bone fusion of pars defect was achieved in all the patients. The average period of bone union was 7.4 months. (2) The visual analogue scale and Oswestry disability index scores were significantly improved after surgery in all patients (P < 0.05). (3) The fixed segment reserved the motion after internal fixation removal. The signal of adjacent intervertebral disc of fixed segment had no changes compared to preoperative MRI. (4) Bone graft to repair isthmus defect plus temporary single segmental screw rod fixation for adolescent lumbar spondylolysis is very effective, the bone fusion is completed, and temporary fixation may effectively alleviate the degeneration of adjacent disc.

Objective To investigate the surgery outcomes between patients with different recovery states measured by visual analog scores (VAS),explore the relationships among surgery outcomes,bone cement,and degrees of pain relief,and to find out the best combination of cement volume and cement distribution for Percutaneous kyphoplasty (PKP).Methods There were 220 patients with 220 vertebra,from January 2012 to January 2014,who received PKP in our hospital.Patients were divided into two groups,on the basis of different VAS.The epidemiological data,operative effect,and surgical complications were compared between two groups.Characteristic curve (ROC) was used to analyze the effect of bone cement dosage and distribution on the diagnosis of patients with different recovery state.The correlation was analyzed between the dose and distribution of bone cement and surgery outcomes.Moreover,logistic regression analysis was used to assess the safety of cement implantation.Results A total of 77 recuperators and 143 non-recuperators were included in the study.Two groups of patients in epidemiological data showed no significant difference.The surgery duration,bone cement injection dose,cement distribution,vertebral height restoration rate and improvement of kyphotic angle in the recuperator group were all significantly higher than those in the non-recuperator group.Whether small dose and large dose of bone cement volume and expanded the bone cement distribution area could significantly improve the patient of operation after the recovery rate and bone cement dose with extensive bone cement distribution area and large bone cement dose with limited bone cement distribution area had the same operation after the recovery effect (x2 =2.880,P =0.090).When the cement volume was constant,cement distribution was positively correlated with the restoration rate of vertebral height and improvement of the kyphotic angle (r2 =0.207,P ＜ 0.01;r2 =0.159,P =0.02).Conclusions The value of cement distribution is better than cement volume in relieving patient pain for diagnostic.For PKP,cement distribution above 0.49 with small cement should be suggested.

BACKGROUND: Most scholars believed that injured vertebral body needs to be fixed in the open surgery of thoracolumbar vertebral fractures; however, it is unclear whether injured vertebra needs to be fixed in the minimaly invasive surgery. OBJECTIVE: To investigate the clinical outcomes of minimaly invasive percutaneous self-dilating pedicle in repair of injured vertebral fixation in thoracolumbar vertebral fractures. METHODS: Totaly 36 patients with thoracolumbar vertebral fractures without nervous system injury who received treatment in Honghui Hospital, Xi’an Jiaotong University Health Science Center from February 2013to February 2014 were enroled and divided into injured vertebral fixation and cross-injured vertebral fixation groups (n=18/group). Patients in these two groups were al subjected to minimaly invasive percutaneous self-dilating pedicle treatment. The injured vertebral body, upper, and lower vertebrae of injured vertebral body were fixed in injured vertebral fixation group, and the upper and lower vertebrae of injured vertebral body was fixed in cross-injured vertebral fixation group. RESULTS AND CONCLUSION: Compared with the injured vertebral fixation group, the cross-injured vertebral fixation group had smaler incisions, less intraoperative blood loss, less operation tine and intraoperative X-ray fluoroscopy time (P < 0.05). After one year of internal fixation, the anterior vertebral height, anterior vertebral height percentage and kyphotic Cobb angle of patients in these two groups improved compared with those before internal fixation (P < 0.05), but there were no significant differences in anterior vertebral height percentage, kyphotic Cobb angle and Oswestry disability index between these two groups (P > 0.05). These results demonstrate that anterior vertebral height cross-injured vertebral fixation has the similar clinical effect with injured vertebral fixation, but cross-injured vertebral fixation had more advantage in the operation. Therefore, there is little significance of conducting injured vertebral fixation in the surgery of minimaly invasive percutaneous self-dilating pedicle in repair of thoracolumbar vertebral fractures.
