PMID: 36412378.)). {{::l5s1mridischerniation.jpg?200|}} ===== Treatment ===== [[L5-S1 disc herniation treatment]] ===== Case series ===== A total of 32 patients (average age: 49.4 years, range: 23-78) with L5-S1 disc herniations were included. The patient to be tested stood next to a table on which they could lean with their hands. The leg closer to the table was fully flexed at the knee, and the other foot was brought to maximum plantar flexion on the toes. At this point, a stopwatch was started to measure the time that passed until the muscles fatigued and the heel fell. The differences between the right and left plantar flexion times were noted. In addition, three different physicians graded muscle strength by using the classical "The Medical Research Council of the United Kingdom" method. The time until fatigue in right and left [[plantar flexion]] was measured using the proposed method, and each test underwent a video recording. The Yilmaz-Ilbay plantar flexion test yielded the correct classification for all cases. They suggest that the proposed method "Yilmaz-Ilbay plantar flexion test" can serve as a useful, practical, and effective test to detect quantitative evaluation of plantar flexion in L5-S1 herniation ((Yilmaz M, Ilbay G, Yilmaz HE, Ertem O, Erbayraktar S, Ilbay KM.

PMID: 36412378.)) ===== Case reports ===== A 72- year-old female patient was admitted to our outpatient clinic complaining of right leg pain for 6 months. A 4/5 motor paresis was observed on her right toe with a positive Lasegue test at 45°. On her magnetic resonance imaging (MRI), a L5-S1 disc herniation was detected. The patient was planned for percutaneous endoscopic interlaminar disc surgery. The extruded disc was adherent to the dura. During removal, a dural tear was observed. She was relieved of her right leg pain immediately after surgery, but after 30 min postoperatively, she complained of double vision with left abducens nerve paralysis. On cranial MRI, no abnormality could be observed. Intravenous fluids were administered and the paralysis resolved on the postoperative 24th hour. The patient was discharged from the hospital and did not show any complaints on her follow-ups. A 6th nerve palsy can be caused due to alterations of intracranial pressure or mechanic injury. We believe that the durotomy following removing of the disc fragment caused a rapid drainage of CSF, leading to intracranial hypotension and injury of the abducens nerve. Intracranial pressure should be monitored perioperatively and brisk deteriorations has to result in immediate finishing of the surgery to avoid further secondary damage ((Avci İ, Gürsoy T, Paksoy K, Şentürk S, Yaman O, Özer AF.

Six hours after surgery, she suffered from [[headache]], nausea, visual disturbance, and seizures. Magnetic resonance imaging revealed [[vasogenic edema]] in the occipital lobe, and she was diagnosed with PRES. Prompt symptomatic treatment resulted in a full recovery at 3 days after surgery. Subsequently, we reviewed the literature pertaining to PRES following spine surgery. The review of the relevant literature on PRES following spine surgery identified 12 cases (male, n = 2; female, n = 10; average age, 59.5 years). Approximately 92% patients received multi-level decompressive laminectomy and/or fusion. This case and the review of the relevant literature suggest that even minimally invasive spine surgery in a young woman with specific characteristics (eg, hypertension) can cause PRES ((Matsuo M, Morimoto T, Kobayashi T, Tsukamoto M, Yoshihara T, Hirata H, Mawatari M.
