Classification and Reliability of Lumbar Facet Cysts Grading Scales

Neuraxial pathology and regional anesthesia: an education guide to decision-making

In current clinical practice, spinal anesthesia and analgesia techniques-including epidural and subarachnoid procedures-are frequently executed without imaging like X-ray or epidurography. Unrecognized spinal pathology has resulted in serious morbidity in the context of performing neuraxial anesthesia. Typically, preoperative consultations incorporate a patient's medical history but lack a detailed spinal examination or consideration of recent MRI or CT scans. In contrast, within the domain of pain clinics, a multidisciplinary approach involving anesthesiologists and neuroradiologists is common. Such collaborative settings rely on exhaustive clinical history and scrutinization of recent imaging studies, which may influence the decision to proceed with invasive spinal interventions. There are no epidemiological data concerning rates of the different baseline pathologies that would potentially pose morbidity risks from neuraxial procedures, but the most common among these is canal stenosis, which significantly affects almost 20% of people over 60 years of age. This paper aims to elucidate these critical findings and advocate for incorporating meticulous preoperative assessments for individuals slated for spinal anesthesia or analgesia procedures, thereby attempting to mitigate potential risks.

Lumbar Synovial Cysts-Should You Fuse or Not?

BACKGROUND

Spinal synovial cysts are lesions that most commonly occur in the lumbar region. The need for an instrumented spinal fusion in addition to lumbar decompression with removal of the synovial cyst is unknown.

OBJECTIVE

To test the hypothesis that select patients who underwent decompression with instrumented fusion for lumbar synovial cysts would be less likely to have subsequent surgery (SS) in a 2-year period than patients treated with laminectomy alone.

METHODS

This retrospective cohort study was performed using IBM MarketScan Commercial Claims and Encounters Database. Patients who had a lumbar synovial cyst diagnosis and laminectomy surgery with or without fusion surgery were included in this study. Patients were tracked for SS 2 years after surgery. Laminectomy patients were propensity score-matched to laminectomy with fusion (LF) patients using a 2:1 ratio. The log-rank test and Cox regression were used to compare the cumulative incidence of SS between groups.

RESULTS

There were 7664 and 1631 patients treated with laminectomy and LF before matching. After matching, there were 2212 laminectomy and 1631 LF patients and patient characteristics were balanced. The 2-year incidence of recurrent SS was 3.1% ([CI]: 2.2%, 4.0%) and 1.7% (95% CI: 0.9%, 2.5%) laminectomy and LF, respectively. Compared with laminectomy, LF had a statistically significant lower risk of recurrent SS (hazard ratio: 0.56 [95% CI: 0.32-0.97]; P -value: .04).

CONCLUSION

All patients who had concomitant lumbar fusion showed decreased chance of having a cyst- or noncyst-related recurrence SS when compared with all patients undergoing laminectomy alone, regardless of diagnosis at the time of SS.
