Objective To explore the effects of single rectangle cage interbody fusion combined with pedicle screw fixa?tion for isthmic spondylolisthesis. Methods Data of the 34 cases with isthmic spondylolisthesis hospitalized at our department from March 2012 to February 2015 were retrospectively analyzed. All cases were operated by posterior pedicle screw fixation com?bined with single rectangle cage interbody fusion. There were 21 males and 13 females, aging from 18 to 63 years old (with an aver?age age of 41.6±8.2 years). Lesion segments were L4 in 15 cases and L5 in 19 cases;there were 12 cases in Meyerding I degree, 16 in II degree and 6 in III degree;28 patients had lower back pain associated with lower limb pain;19 patients had lower back pain associated with numbness of lower limb;18 patients had lower back pain associated with lower limb muscle weakness and 2 pa?tients had urination and defecation function disturbance. The surgical operation time, bleeding, postoperative drainage flow, graft fusion rate, complications were measured, and the intervertebral disc height, Japanese Orthopaedic Association (JOA), Oswestry disability indes (ODI), visual analogue scale (VAS) score were compared before and after treatment. Results The operation of 34 patients was successfully completed with the average operation time of 1.8 ± 0.8 h, and the bleeding in operation was 362.4 ± 93.7 ml, while postoperative drainage flow was 116.3±54.2 ml. All patients were effectively followed up for 12 months to 46 months (av?erage, one year and 10 months). Two weeks after operation, the intervertebral disc height were obviously increased (9.85±1.11 mm, 9.63 ± 1.04 mm), and there were significant difference compared with preoperative results (6.53 ± 0.98 mm, 6.24 ± 1.07 mm), but there were no significant difference compared with the latest follow?up results (9.23±1.33 mm, 9.30±1.16 mm). At the latest follow?up, JOA score was 13.19±1.08, ODI score 12.34±7.52, VAS score 2.23±1.51, and there were significantly different in each score compared with preoperative results. The symptoms of low back pain, lower limb nerve dysfunction and quality of life were signifi?cantly improved compared with preoperative situation. At the 16 month follow?up, all postoperative patients with vertebral body bone graft were judged to be fused. There was no pedicle screw loosening, fracture and so on. Conclusion Single rectangle cage interbody fusion combined with pedicle screw fixation for the treatment of isthmic spondylolisthesis is a kind of mini?invasive, less bleeding, safe and effective surgical method.

BACKGROUND: To repair bone defect, histocompatibility, growing characteristics, biodegradation and repairing mechanism of nanometer need to be further studied in clinic. OBJECTIVE: To observe the growing characteristics and histocompatibility of nano-hydroxyapatite (Nano-HA) for repairing jaw defect of rabbits.DESIGN: Randomized grouping animal study.SETTING: Beijing Jishuitan Hospital and Stomatology College of Jiamusi University.MATERIALS: A total of 24 New Zealand rabbits, either gender, weighing 2.5-3.5 kg, were provided by Animal Experimental Center of Jiamusi University. The animal experiment had got confirmed consent from local ethic committee. Nano-HA was provided by Material Engineering College of Jiamusi University and dealt with routine hyperthermia/hypertension sterilization. In addition, hydroxyapatite was provided by Wuhan Industry University, and the diameter was 1.0-2.0 μm.METHODS: The experiment was carried out in the Experimental Animal Center of Jiamusi University from November 2001 to May 2006. All rabbits were randomly divided into experimental group and control group with 12 in each group. Bone defect in the diameter of 1.0 cm was produced on body of mandible. Nano-HA was used to repair the bone defect of rabbits in the experimental group, while hydroxyapatite was used to repair the bone defect of rabbits in the control group. At 1, 4, 8 and 12 weeks after operation, all rabbits were sacrificed. In addition, medical imaging analysis system was used to analyze generative quantity of tissue in the two groups; meanwhile, histological quality and quantity were also analyzed so as to observe histocompatibility and newborn osteogenesis. MAIN OUTCOME MEASURES: Histocompatibility and newborn osteogenesis.RESULTS: With the time passing by, the amount of repairing materials was decreased because of the combination with newborn tissue into bone in bone defect-repaired region in the experimental group. When it was closed to normal bone, the amount was stable. However, bony callus was not able to grow in materials in the control group. Results of correlation analysis demonstrated that materials were negatively straight-line correlation with newborn bone (r = -0.912 0, P < 0.01). During the repairing procedure of bone defect, newborn bone was closely correlative with Nano-HA; while, with the increase of newborn bone, the amount of repairing materials was decreased because of the combination with newborn tissue into bone.CONCLUSION: Nano-HA can combine with newborn bone tissue so as to rapidly generate bone, while it has an excellent biocompatibility.
