Objective : In Asians, kneeling and squatting are the postures that are most often induce common peroneal neuropathy. However, we could not identify a compatible compression site of the common peroneal nerve (CPN) during hyper-flexion of knees. To evaluate the course of the CPN at the popliteal area related with compressive neuropathy using magnetic resonance imaging (MRI) scans of healthy Koreans. Methods : 1.5-Tesla knee MRI scans were obtained from enrolled patients and were retrospectively reviewed. The normal populations were divided into two groups according to the anatomical course of the CPN. Type I included subjects with the CPN situated superficial to the lateral gastocnemius muscle (LGCM). Type II included subjects with the CPN between the short head of biceps femoris muscle (SHBFM) and the LGCM. We calculated the thickness of the SHBFM and posterior elongation of this muscle, and the LGCM at the level of femoral condyles. In type II, the length of popliteal tunnel where the CPN passes was measured. Results : The 93 normal subjects were included in this study. The CPN passed through the "popliteal tunnel" formed between the SHBFM and the LGCM in 36 subjects (38.7% type II). The thicknesses of SHBFM and posterior portions of this muscle were statistically significantly increased in type II subjects. The LGCM thickness was comparable in both groups. In 78.8% of the "popliteal tunnel", a length of 21 mm to <40 mm was measured. Conclusion : In Korean population, the course of the CPN through the "popliteal tunnel" was about 40%, which is higher than the Western results. This anatomical characteristic may be helpful for understanding the mechanism of the CPNe by posture.

In Oriental Medicine, mononeuropathy belongs to or . Common peroneal neuropathy(CPN) is the most frequently encountered mononeuropathy in the lower extremity. It is usually caused by direct surgery injury, compression, leg crossing, trauma, traction etc, occasionally by nerve tumor. A 47-year-old healthy man was complained of the sudden development of left foot drop and sensory manifestation owing to suspected compression and habitual leg-crossing. Acupuncture along with bee-venom acupuncture, moxibustion was performed mainly at Stomach and Gallbladder Meridian specially ST36, ST37, ST40, GB34 and GB39. Nerve conduction study and electromyography was also performed three times. Symtoms was relieved fast, and full recovery took about 110 days. Acupuncture and bee-venom acupuncture are considered to be beneficial to CPN. More clinical trials and studies are needed.

The purpose of this study is to report that a patient suffered from Common Peroneal Neuropathy (CPN) caused by ankle sprain was improved by acupuncture plus electro-acupuncture. In this study, the patient was diagnosed with magnetic resonance image(MRI) and electomyography(EMG). We treated at acupoints ST36, ST41, SP9, GB34, GB39 and LR3 by acupuncture plus electro-acupuncture twice a day for 16 days; a total of 30 times. We used evaluation scale including muscle manual testing(MMT) and visual analogue scale (VAS). MMT changed from Grade 0 to Grade 5 and VAS changed from 10 to 2 after treatment for 16days with hospitalization. Though it is a case report, these results suggest that acupuncture and electrical acupuncture might have valid effect on CPN in controlled environment.

Objective : We aimed to analyze the effectiveness of external neurolysis on the common peroneal nerve (CPN) in patients with posture-induced compressive peroneal neuropathy (PICPNe). Further, we aimed to examine the utility of magnetic resonance imaging (MRI) in assessing the severity of denervation status and predicting the postoperative prognosis. Methods : We included 13 patients (eight males and five females) with foot drop who underwent CPN decompression between 2018 and 2020. We designed a grading system for assessing the postoperative functional outcome. Additionally, we performed MRI to evaluate the denervation status of the affected musculature and its effect on postoperative recovery. Results : The median time to surgery was 3 months. The median preoperative ankle dorsiflexion and eversion grades were both 3, while the average functional grade was 1. Posterior crural intermuscular septum was the most common cause of nerve compression, followed by deep tendinous fascia and anterior crural intermuscular septum. There was a significant postoperative improvement in the median postoperative ankle dorsiflexion and eversion grades and average postoperative functional (4, 5, and 2.38, respectively). Preoperative ankle eversion was significantly correlated with denervation status. Additionally, the devernation status on MRI was positively correlated with the outcome favorability. However, denervation atrophy led to a less favorable outcome. Conclusion : Among patients with intractable PICPNe despite conservative management, surgical intervention could clinically improve motor function and functional ability. Additionally, MRI examination of the affected muscle could help diagnose CPNe and assess the postoperative prognosis.
