My 15 year old daughter has a lytic spondylolisthesis at L5/S1. She has had mid and lower back pain for over 18 months. This has not resolved despite rest and stopping gymnastics, ice skating and other sports. The MRI shows “multiple mature dorsal osteophytes anteriorly. The L5 vertebra is 2mm in front of S1. Disc shows borderline narrowing, but axials show no disc herniation.
A surgeon has suggested she have a Direct Pars Repair with “hook instrumentation” taking a bone graft from her vertabra and packing it in the fractures.
Would the above procedure be a good option? Why or why not?
If a pars repair is not likely to succeed, then which type of spinal fusion and what approach and instrumentation be the best option?
If she is still growing is surgery likely to fail?
Should she wait, or is it better to do the surgery right now to prevent a further slip?
Is it inevitable that the slip is likely to progress?
Should a Pars Repair be tried before doing a spinal fusion?
Please explain MRI results. Are the osteophytes abnormal?
Does anyone out there have a similar disorder or know someone with it?
Any help would be gratefully appreciated.
