| Popis: | Minimally invasive posterior spinous process–splitting laminoplasty preserving the paraspinal musculature has been introduced to treat patients with lumbar spinal stenosis. Despite its theoretical advantage of limiting muscular trauma, additional efforts are required to evaluate patients' clinical and functional results following this procedure. Between 2010 and 2012, 37 patients underwent spinous process–splitting laminoplasty for lumbar stenosis at a mean age of 68 years (range, 36–87 years) and were followed for minimum of 1 year (mean, 1.3 years). There were 22 (59%) men and 15 (41%) women. Mean number of levels treated with a spinous process–splitting laminoplasty was 2.2 (range, 1–6 levels). Patients had statistically significant improvements in their scores for all self-reported outcomes, including visual analog scale (VAS) for back and leg pain, Oswestry Disability Index (ODI), and Short Form 36 (SF-36) components. Mean VAS significantly decreased by 4.4±3.2 points for back pain and 3.9±3.7 points for leg pain ( P P P =.0017) for the physical component and 21.8±25.6 points ( P =.0062) for the mental health component. Four (10.8%) patients had a dural tear requiring repair (3 were intraoperative), 3 (8%) had an epidural hematoma requiring evacuation, 1 (2.7%) had an infection requiring irrigation and debridement, and 2 (5%) had additional decompression for symptom recurrence secondary to instability. Lumbar spinous process–splitting laminoplasty is a novel minimally invasive technique that provides adequate decompression for the neuronal elements and may avoid extensive paraspinal muscular damage associated with conventional laminectomy. Patients demonstrated significant improvements in pain and overall heath and function scores at a minimum 1-year follow-up. [ Orthopedics. 2016; 39(5):e950–e956.] |
