Introduction The effectiveness of segmental wire fixation technique in repairing lumbar spondylolysis has already been reported. However,
whether the technique can be indicated for spondylolysis associated with spina bifida, which is occasionally found with spondylolysis,
is not well known. In this study, the authors report the mid-term clinical outcome of the procedure performed in patients
with symptomatic lumbar spondylolysis associated with spina bifida occulta.
Materials and methods Among 20 patients with symptomatic lumbar spondylolysis who underwent segmental wire fixation between 1996 and 2001, four
patients associated with spina bifida occulta were evaluated with an average of 32 months follow-up. Bony union at spondylolysis
sites and spina bifida was evaluated using plain X-rays and computed tomography (CT) scans. Clinical symptoms were assessed
using Japanese Orthopedic Association scores for back pain (JOA scores) and Henderson’s evaluation of functional capacity.
Results The radiographic examinations of the latest follow-ups revealed the following results. Pars defect; in three cases with bilateral
defect, one case healed bilaterally and two healed only unilaterally. One case with unilateral defect healed. Spina bifida;
two cases showed bony union and two showed no union. Of the four patients operated, two were rated excellent with the remaining
two good according to Henderson’s evaluation. The recovery rate of JOA score was averaged at 69.7 ± 23.5%. No serious complications
were noted.
Conclusions In four cases associated with lumbar spondylolysis and spina bifida, segmental wire fixation provided satisfactory clinical
outcomes. 相似文献

Direct repair of multiple levels lumbar spondylolysis by pedicle screw laminar hook and bone grafting: clinical, CT, and MRI-assessed study 总被引:1,自引:0,他引:1
INTRODUCTION: A prospective analysis of 6 cases with multiple-level spondylolysis treated by direct repair with pedicle screw laminar hook is presented. The objective of the study was to evaluate the clinical outcome, plain radiographs, computed tomography (CT) scan, and magnetic resonance imaging to demonstrate the result of direct repair in the treatment of multiple-level spondylolysis. MATERIALS AND METHODS: Ten patients with multiple-level spondylolysis of lumbar spine were treated with segmental pedicle screw hook fixation and autogenous bone graft. Four patients had lost follow-up. Six patients were followed up for a minimum of 2 years (mean 34.3 mo, range 24 to 55 mo). Patient's average age was 22 years old (range from 20 to 25 y old). All lytic defects were bilateral and located at 2 different lumbar vertebras (levels). CT scans and MR images were obtained at the latest follow-up postoperatively to assess the healing of the bony defects and the adjacent disc conditions. Fusion was considered to be presented when trabecula across the lytic defect was detected. RESULTS: The union rate was 87% (21 pars/24 pars) on plain radiographs and 75% (18 pars/24 pars) on CT scans. Follow-up magnetic resonance imaging of lumbar spine showed no disc degeneration. All patients were satisfied (either excellent or good) with the postoperative outcomes. CONCLUSIONS: Direct repair of multiple-level spondylolysis by pedicle screw laminar hook and autogenous bone graft would be the alternative of treating patients with persistent back pain after 6 months of conservative treatment The favorable clinical outcome was correlated with bony healing rate in this series. 相似文献

Direct defect repair using segmental pedicular screw hook fixation was carried out in nine patients with spondylolysis and a mean age of 24.2 years. One patient was fused 3 years after isthmic reconstruction. In the remaining eight patients, after a mean follow-up of 41 months (range, 12-78), three self-evaluation scales revealed a significant (p < 0.05) improvement in clinical status. Computed tomography scans were carried out in seven patients. There was bilateral bony union in two cases, in three pars healing was unilateral, and in two the isthmic defect persisted bilaterally. No correlation was observed between the status of the pars and follow-up. We conclude that repair of defects in spondylolysis may result in a favorable clinical outcome even when anatomic reconstruction of pars interarticularis is not successful. 相似文献

We describe the results of a prospective case series of patients with spondylolysis, evaluating a technique of direct stabilisation of the pars interarticularis with a construct that consists of a pair of pedicle screws connected by a U-shaped modular link passing beneath the spinous process. Tightening the link to the screws compresses bone graft in the defect in the pars, providing rigid intrasegmental fixation. We have carried out this procedure on 20 patients aged between nine and 21 years with a defect of the pars at L5, confirmed on CT. The mean age of the patients was 13.9 years (9 to 21). They had a grade I or less spondylolisthesis and no evidence of intervertebral degeneration on MRI. The mean follow-up was four years (2.3 to 7.3). The patients were assessed by the Oswestry Disability Index (ODI) and a visual analogue scale (VAS). At the latest follow-up, 18 patients had an excellent clinical outcome, with a significant (p < 0.001) improvement in their ODI and VAS scores. The mean ODI score at final follow-up was 8%. Assessment of the defect by CT showed a rate of union of 80%. There were no complications involving the internal fixation. The strength of the construct removes the need for post-operative immobilisation. 相似文献

Biomechanical and clinical study on screw hook fixation after direct repair of lumbar spondylolysis 总被引:1,自引:0,他引:1
Objective : To evaluate the biomechanical effect and clinical results of hook screw fixation after direct repair of lumbar spondylous defects in the pars interarticularis. Methods: L2-L6 spines of 8 fresh-frozen and thawed calf cadavers were used for mechanical testing. Bilateral spondylous defects were created in the L4 vertebra. The intervertebral rotation ranges between L4 and L5 were scanned and computerized in various states of motion, such as flexion/extension, lateral bending and torsional loadings applied on the intact spine and the spondylous spine when the spondylous spine was fixed with modified Scott' s fixation, hook screw fixation and Buck ' s fixation sequentially and respectively. Between July 2002 and February 2004, 14 young male patients (aged 15-31 years) suffering from symptomatic lumbar spondylolysis were treated with TSRH hook screw fixation after direct repair of the defects. MacNab criteria were used to assess their pre-and post-operative status. Results: Each fixation technique could significantly increase the intervertebral rotational stiffness and made the stiffness return to nearly the intact level. Hook screw technique provided more rotational stability than the others. Hook screw and Buck' s techniques provided more flexion/extension stability than modified Scott' s technique. Neither complication nor instrumental failure was observed in this study. The mean follow-up period was 21 months. All the patients except one acquired union during the follow-up period. Thirteen patients had a“good”or“excellent”result according to MacNab criteria. Conclusions: Hook screw fixation shows biomechanical advantages and is safe and effective for young patients with lumbar spondylolysis. 相似文献

BACKGROUND: A nonunion of the pelvic ring after a pathologic or insufficiency fracture of osteopenic bone is rare. The purpose of the present study was to evaluate the radiographic and clinical results of in situ fixation of these nonunions. METHODS: The records of forty-four patients who had been managed with in situ fixation of pelvic fracture nonunions were reviewed retrospectively. Twenty-seven patients had sustained pathologic fractures after a simple fall, and seventeen had sustained insufficiency fractures. Forty-two of the forty-four nonunions were unstable and were located unilaterally or bilaterally in the posterior pelvic arch, and thirty-six involved the lateral aspect of the sacrum. Two of the forty-four non-unions involved only the pubic rami. The average age of the patients was sixty-six years (range, thirty-five to eighty-seven years), and the average duration of postoperative follow-up was four years (range, two to eleven years). All patients were assessed with regard to fracture union, residual pelvic pain, pelvic instability, and functional status. In addition, all patients were asked to rate the surgical result as highly satisfactory, satisfactory, or unsatisfactory. RESULTS: Thirty-six (82%) of the forty-four nonunions healed after in situ fixation, and seven of the eight persistent nonunions healed after additional surgery. Thirteen patients (30%), including five patients who had radiographic evidence of union, had persistent pain at the one-year follow-up assessment. None of the forty-three patients in whom the fractures eventually healed complained of persistent pelvic instability. At the time of the final follow-up examination, twenty-four patients (55%) were highly satisfied, twelve (27%) were satisfied, and eight (18%) were unsatisfied with the surgical result. CONCLUSIONS: In situ fixation of a nonunion of the pelvic ring following a pathologic or insufficiency fracture can result in a decrease in pelvic pain and instability along with an improvement in walking ability. A high percentage of patients complain of persistent pain, even if there is radiographic evidence of union of the pelvic ring. 相似文献

Bone defect in the lumbar articular facet is rarely noted, and only a few reports on its clinical course have been presented. We report on seven cases with lumbar inferior facet defect whose symptoms were mimicking spondylolysis. We have found three types of the defect shape on radiographs: linear, blunt, and irregular. There were five cases with linear type, one with blunt, and one with irregular. All patients had persistent low back pain, especially when doing physical activity or sports, but no one had history of major trauma or accident. Injection of a small amount of anesthetic temporarily alleviated the low back pain. The low back pain in six patients was controlled with conservative treatments, such as bracing or medication; bone union was especially gained in one case. However, a volleyball player's pain could not be controlled conservatively, and removal of the bone fragment was performed. It is considered that facet defect is not as rare as presumed, and more attention should be paid to it as a source of low back pain. 相似文献

The aim of this retrospective study was to assess clinical outcomes after segmental wire fixation and bone grafting for repair of pars defects in patients with multiple-level lumbar spondylolysis. Subjects were 7 patients (5 men and 2 women, mean age 26.7 y) with multiple-level lumbar spondylolysis treated by segmental wire fixation and bone grafting at one of our affiliated institutions between 1983 and 2004. Clinical outcomes were determined by comparing preoperative and postoperative Japanese Orthopaedic Association scores and Mancab criteria, and healing of pars defects was evaluated by radiographic and computed tomography study. The condition involved 2 levels in 5 cases and 3 levels in 2 cases. The mean postoperative follow-up period was 51.0 months. The mean Japanese Orthopaedic Association score improved significantly from 21.29 before surgery to 27.86 after surgery, and the recovery rate was 85.21%. An "excellent" result was achieved in 5 cases, a "good" result in 1 case and a "fair" result in 1 case according to the Macnab criteria. Postoperative radiographs revealed healing of all defects in 4 cases, healing of 3 out of 4 defects in 2 cases, and no healing of any defect in 1 case. Pseudoarthrosis was related to wire breakage, and patients who did not obtain complete healing were patients who did not fully comply with instructions to wear a lumbar corset or restrict activity postoperatively. Segmental wire fixation and bone grafting were shown to be effective for multiple-level lumbar spondylolysis. 相似文献
