Juxtafacet Spinal Synovial Cysts.

Abd El-Kader Hel-B - Asian Spine J (2016)

Bottom Line: An excellent or good outcome was considered as satisfactory.All patients included in this study had excellent outcomes as regarding to improvement of all preoperative manifestations and returning to normal daily activities.Only 2 cases developed postoperative transient cerebro-spinal fluid leak and were treated conservatively and improved during the follow up period.

ABSTRACT

Study design: This was a retrospective study.

Purpose: To study the surgical outcome of synovial cysts of the lumbar spine through posterior laminectomy in combination with transpedicular screw fixation.

Overview of literature: Synovial cysts of the lumbar spine contribute significantly to narrowing of the spinal canal and lateral thecal sac and nerve root compression. Cysts form as a result of arthrotic disruption of the facet joint, leading to degenerative spondylolisthesis in up to 40% of patients.

Methods: Retrospective data from 6 patients, treated during the period of March 2007 to February 2011, were analyzed. All preoperative and postoperative manifestations, extension/flexion radiographs, magnetic resonance imaging, and computed tomography records were reviewed. All underwent surgery for synovial cysts with excision and decompression combined with posterior fixation. The result of surgery was evaluated with Macnab's classification. An excellent or good outcome was considered as satisfactory. Japanese Orthopedic Association Scale was used for evaluation of back pain.

Results: All patients included in this study had excellent outcomes as regarding to improvement of all preoperative manifestations and returning to normal daily activities. Only 2 cases developed postoperative transient cerebro-spinal fluid leak and were treated conservatively and improved during the follow up period.

Conclusions: Although this study included a small number of cases and we could not have statistically significant results, the good outcome of decompression of synovial cysts combined with posterior fixation and fusion encouraged us to recommend this approach for patients with juxtafacet synovial cysts.

Mentions: Confirmation of diagnosis was done through X-ray radiographs (including dynamic films), CT, and MRI (Figs. 1, 2). After selection of patients and obtaining surgical consent, all the patients included in the study underwent decompression with excision of the synovial cyst through posterior laminectomy combined with transpedicular screw fixation and posterolateral fusion (PLF) (Fig. 3). All the possible samples retrieved during surgery (Fig. 4) were sent for histological examination (Fig. 5).
