There were studied up the morphofunctional changes of vertebral motor segments in 21 patients with vertebral osteochondropathy as well as with initial spondylolysis and spondylolisthesis. The patients were from 12 to 21 years old, the average follow-up was 4.5 years. In vertebral deformity in sagittal plane the spondylolystic spondylolisthesis was not revealed in patients, and in particular the leading clinical sign presented was the syndrome of spondyloarthrosis on the level of compensational hyperlordosis; in vertebral osteochondropathy with preserved or the smoothed physiologic vertebral curvatures--dysplastic spondylolisthesis with early occurrence of hyperplastic spondyloarthrosis as a consequence of the Schmorl's hernia in middle lumbar vertebral segments and of instability of the lower lumbar segments due to vertebral sliding shift with subsequent occurrence of hyperplastic spondyloarthrosis predominantly on these levels. The presence of hyperplastic spondyloarthrosis in lower lumbar vertebral segments while overextension causes the risk rise of the vertebral canal stenosis occurrence.

Progression of spondylolysis to spondylolisthesis in adults is very rare. It is always accompanied by disc degeneration at the slip level, or at a lower level. The intervertebral disc is indeed the main structure that opposes the anteriorly directed shear forces. Of course, the disc degeneration might also be a consequence, rather than a cause of the slip. The authors describe an unusual case of progression of spondylolysis to spondylolisthesis in an adult, without any disc degeneration. They are not aware of a similar case in the literature. In 1999, an aircraft engineer with known asymptomatic spondylolysis was involved in a low impact motorcycle accident, after which a Grade I spondylolisthesis L4 was diagnosed. There was no predisposing disc space narrowing at any vertebral level. There may have been a certain degree of microscopic disc degeneration L4L5, a possibility which was confirmed by the development of a disc hernia L4L5, seven years after trauma. This case illustrates the potential for progression of spondylolysis to spondylolisthesis in an adult, without radiographical signs of disc degeneration at any level. The minimal trauma might have played a role. The authors recommend that patients with known spondylolysis who sustain acute exacerbation of their back pain should have standing radiographs.

Approximately 80% of the adult population suffers from chronic lumbar pain with episodes of acute back pain. The aetiology of this disorder can be very extensive: degenerative scoliosis, spondiloarthritis, disc hernia, spondylolysis, spondylolisthesis and, in the most serious cases, neoplastic or infectious diseases. For several years, the attention of surgeons was focused on the articular facets syndrome (Lilius et al. in J Bone Joint Surg (Br) 71-B:681-684, 1998), characterised clinically by back pain and selective pressure soreness at the level of the facets involved. The instrumental framework highlights widespread zigoapophysary arthritis and hypertrophy/degeneration of articular facets due to a functional overload. This retrospective study analyses the patients who arrived at our observation and were treated with a neuroablation using a pulsed radiofrequency procedure, after a CT-guided infiltration test with anaesthetic and cortisone. From the data collected, it would seem that this procedure allows a satisfactory remission of the clinical symptoms, leaving the patient free from pain; furthermore, this method can be repeated in time.
