“…There are many of etiological factors associated with DGS (e.g., direct trauma of buttock or pelvis, hypertrophy of muscles in deep gluteal region, hematoma or neoplasm and anatomical variants the between piriformis and sciatic nerve 4 17 18) ). As shown in our study, DGS can occur in various locations; although none of the cases in our study were caused by trauma, various distributions and nerve variations were present in one case which has been described as Type 2 according to Beatons and Anson's classification.…”

PurposeThe purpose of this retrospective study was to evaluate clinical outcomes of endoscopic nerve decompression in patients with deep gluteal syndromes (DGS).Materials and MethodsBetween October 2013 and March 2015, 24 patients who underwent surgical treatment of DGS were retrospectively included in this study. The mean age was 47 years (range, 35 to 76 years), and there were 11 males and 13 females. The mean duration of pain was 12 months (range, 5 to 35 months) and the mean follow-up period was 32 months (range, 26 to 45 months). Clinical evaluations included the visual analog scale (VAS) pain score, modified Harris hip score (mHHS), and the symptom-rating scale.ResultsSignificant improvement in symptoms following endoscopic decompression were achieved as measured using the VAS score (decrease in the mean from 7.1±0.9 to 2.5±1.5; P<0.001) and mHHS (increase from 59.4±6.5 to 85.0±8.3; P<0.001).ConclusionEndoscopic sciatic nerve decompression was satisfactory for treating recalcitrant DGS, making it an effective treatment option to improve symptoms of DGS.

“…However, any structures in deep gluteal region can cause this syndrome by compression sciatic nerve, so sciatic nerve entrapment syndrome or deep gluteal syndrome may be a proper representation [ 16 ]. There are a number of etiological factors of sciatic nerve entrapment syndrome, such as direct trauma of buttock or pelvis, hypertrophy of muscles in deep gluteal region, hematoma or neoplasm and anatomical variants between piriformis and sciatic nerve, etc [ 17 – 19 ]. Be aware of possible anatomical variation bifurcation of the sciatic nerve through the muscles.…”

BackgroundThe purpose of this study is to assess the effectiveness of endoscopic sciatic nerve decompression and evaluated the differences of clinical results between atraumatic and traumatic groups.MethodsSixty consecutive patients. We retrospectively reviewed sixty consecutive patients without major trauma (45 hips) or with major trauma (15 hips) groups to compare the outcomes of endoscopic treatment.). The mean follow-up period was 24 ± 2.6 months (range, 24–38.4 months).ResultsThe mean duration of symptoms was 14.1 months (range, 12 to 32 months). Compromising structures were piriformis muscle, fibrovascular bundles, and adhesion with scar tissues. The mean VAS score for pain decreased from 7.4 ± 1.5 to 2.6 ± 1.5 (P = .001). The mean mHHS increased from 81.7 ± 9.6 to 91.8 ± 7.6 (P = .003). Clinically, positive paresthesia and seated piriformis test were statistically significant to diagnosis sciatic entrapment syndrome. Paresthesia and sitting pain were significantly improved at the final follow-up (P = .002). More favorable outcome was observed a group without major trauma. No complication was observed.ConclusionsEndoscopic sciatic nerve decompression is a safe and effective procedure for the management of DGS. Patients with major trauma could have poor clinical outcome. Seated piriformis test, FADIR, and tenderness of sciatic notch are maybe useful guide for pre and postoperative evaluation of DGS.

“…In previous reports, CEH was shown to occur in many locations, such as the calf, 5 thigh, 7–10 knee, 11 buttocks, 12 abdomen, 6 pelvis, 13 thorax, 14 and breast, 15 and often simulated neoplasms. It is thought that the initial hemorrhage is caused by trauma due to surgery, 6,8,13,15 minor blunt trauma, 7,11 or gunshot wound.…”
