Chondrosarcomas located in the spine are uncommon tumors and are challenging to manage. A case of a 65-year-old man with a T3-T4 spine chondrosarcoma is reported. The onset of symptoms consisted in progressive dorsal pain with sometimes a girdle-like radiation and, successively, in dysaesthesia and paresthesia from the lower limbs to the thoracic region. ⋯ An adjuvant radiation therapy with a dose of 5.500 centigrays (cGy) over four weeks was performed. At one year follow-up the patient is alive with no signs of recurrence on computed tomographic scans and magnetic resonance imaging. We discuss this case with particular emphasis on the preoperative planning, the surgical procedure and related prognosis.

Postlumbar laminectomy syndrome, or pain following operative procedures of the lumbar spine, is increasingly a common entity in modern medicine. Multiple causes proposed for recurrence of pain after lumbar laminectomy are: epidural fibrosis, recurrent disc herniation, instability, and facet joints. Even though the prevalence of persistent low back pain secondary to the involvement of lumbosacral facet joints has been described in controlled studies from 15% to 45%, the prevalence of facet joint mediated pain in postlumbar laminectomy syndrome has not been studied. ⋯ Results showed that the prevalence of facet joint mediated pain in non-surgical patients was 44% compared to 32% in post surgical patients determined by comparative controlled local anesthetic blocks utilizing lidocaine and bupivacaine. This study also showed a false positive rate of 36% in non-surgical group and 24% in post-surgical group. In conclusion, this study shows that facet joint mediated symptomatology in chronic low back pain is prevalent, both in non-surgical as well as post-surgical patients even though prevalence was somewhat higher in the non-surgical group compared to post-surgical group.

Epidural fibrosis is seen as a common phenomenon among postlumbar laminectomy syndrome patients, contributing to approximately 60% of symptom recurrence. Percutaneous epidural lysis of adhesions has been described as a modality to effectively manage chronic low back pain secondary to epidural fibrosis. Forty-five patients were randomly assigned, with fifteen patients in the control group, or Group I, who were treated with conservative modalities of treatments, including medication, physical therapy, and an exercise program; and, thirty patients in Group II, who were treated with percutaneous epidural adhesiolysis and hypertonic saline neurolysis. ⋯ The study also showed that overall health status improved significantly in the treatment group in all parameters with average pain, physical health, mental health, functional status, psychological status and narcotic intake. Analysis also showed that this is a cost-effective treatment, with cost for 1-year improvement of quality of life at $2693. In conclusion, epidural adhesiolysis with hypertonic saline neurolysis performed on a 1-day basis is an effective modality of treatment in managing chronic low back pain in patients who failed to respond to fluoroscopically directed epidural steroid injections and also were demonstrated not to have facet joint mediated pain.
