    Investigation of Lateral Epicondylitis in Neurosurgeons
    (2019) Polat, Ömer; Tuncer, Cengiz; Katı, Yusuf Alper; Uckun, Ozhan Merzuk; Er, Uyğur
    AIM: To investigate the frequency of lateral epicondylitis (LE), depending on the tasks performed by neurosurgeons, and to determinewhether it can be accepted as an occupational disease depending on its frequency.MATERIAL and METHODS: All neurosurgery specialists enrolled in the Turkish Neurosurgical Society website were prospectively included. A questionnaire form was shared, and the subsequent responses were recorded. Those who provided incomplete responseswere excluded from the study. The respondents diagnosed with LE were recorded. Exclusion criteria were investigated on complaints ofpain. They were examined by an orthopedics and traumatology specialist with application of Thomsen test and necessary maneuvers.RESULTS: The study was conducted with 216 neurosurgeons. Those with more than 30 operations per month (p=0.002), those with aspecialization duration of 10–20 years and >20 years (p=0.001), and those who specialized in spinal surgery (p=0.014) had a significantlyhigher prevalence of epicondylitis. Considering the relationship between lumbar/thoracic pedicle screw insertion and epicondylitis, theepicondylitis diagnosis rate was significantly higher in physicians inserting 20–60 screws per month than those inserting <20 screws(p=0.009).CONCLUSION: LE frequently occurs in neurosurgeons who regularly perform spinal instrumentation and appears to be an occupationaldisease. However, data obtained during the current study should be combined with findings from case-control studies of neurosurgeons.

    The Preventative Effect of ?-Tocopherol on Spinal Epidural Fibrosis After Laminectomy in a Rat Model
    (2019) Tuncer, Cengiz; Subası, Canan; Dinç, Cem; Türkoğlu, Erhan; Er, Uyğur
    AIM: To assess the efficacy of ?-tocopherol as a topical antifibrotic agent on epidural fibrosis in lumbar laminectomy procedures.MATERIAL and METHODS: A total of 32 adult rats were assigned into four groups, with eight rats in each group. Standardlaminectomy was performed in every rat. In group 1, no treatment was administered after laminectomy. In group 2, a saline-soakedabsorbable gelatin sponge was left on the dura mater after laminectomy. In group 3, only ?-tocopherol was used on the dura materafter laminectomy. In group 4, a gelatin sponge soaked with ?-tocopherol was used after laminectomy. En bloc vertebral columnsbetween T10 and L5 were removed after sacrifice on postoperative day 30. Specimens were evaluated for degree of fibrosis andarachnoidal invasions.RESULTS: Statistically significant differences were found in the mean of fibrosis grades between groups (p=0.001). Differences inmean arachnoidal invasion were not statistically significant (p>0.05).CONCLUSION: Topical application of ?-tocopherol could effectively reduce the development of epidural fibrosis in an experimentallaminectomy model.
