In situ fusion for spondylolysis” is regaining its lost popularity
Authors
Abstract:
Abstract Background: Spondylolysis and spondylolisthesis can be associated with significant low back pain, especially in physically active adolescents. Non-operative management is usually successful in improving symptoms, but surgical intervention is occasionally required. The aim of this study was to determine the effect of in situ posterolateral fusion in the treatment of refractory cases with spondylolysis. Methods: In this prospective before and after study, we described our experience in13 patients managed by in situ fusion after failing multimodality non-operative treatment. All surgical procedures were performed by the senior author and by a similar technique. The spondylolytic vertebra and the one below were fused, in situ. Finally, clinical outcome and recovery rates of clinical symptoms were evaluated by Henderson’s functional capacity and Oswestry Disability Index version 2.1, respectively. Results: The mean duration of non-operative management was 36 (12-72) months. There were 8 males and 5 females. Average pre- and postoperative Oswestry Disability Indices were 28.4%±13.7% and 4.9±7.8 respectively (P=0.001, significant). All patients had follow-up contact on an average of 42.3 months (range 30 - 62 months). Based on Henderson’s clinical outcome functional capacity at the final follow- up stage clinical outcomes were excellent in 10, good in 2 and poor in 1 patient. The case with poor result had a pseudoarthrosis and was re-oprated. Finally he had an excellent outcome. Conclusion: We accept that the number of our cases is not high significantly but it can be claimed that in situ fusion is a safe and effective modality to treat symptomatic patients with spondylolysis and low-grade spondylolisthesis. A study with much more cases is strongly recommended.

full textAcquired spondylolysis after spinal fusion.
Spondylolysis occurring after a spinal fusion is considered to result from operative damage to the pars interarticularis on both sides. Fourteen cases are reported, and compared with the 23 cases which have previously been published. The defects are usually recognised within five years of fusion, and usually occur immediately above the fusion mass. Other contributory causes may be: fatigue frac...

Cervical spondylolysis is a rare condition defined as a corticated cleft at the pars interarticularis in the cervical spine. This is the case of C2 spondylolysis demonstrating progressive significant instability, which was successfully treated by anterior cervical discectomy and fusion (ACDF) with cervical anterior plate. We describe a 20-year-old female with C2 spondylolysis presenting with pr...
