Piriformis syndrome (PS) is an uncommon neuromuscular disorder caused by the piriformis muscle (PM) compressing the sciatic nerve (SN). The main symptom of PS is sciatica, which worsens with certain triggering conditions. Because the pathophysiology is poorly understood, there are no definite diagnostic and therapeutic choices for PS. This case report presents a young woman who mainly complained of bilateral leg weakness. Electromyography revealed bilateral sciatic neuropathy and magnetic resonance imaging confirmed structural lesions causing entrapment of the bilateral SNs. After a laborious diagnosis of bilateral PS, she underwent PM releasing surgery. Few PS cases present with bilateral symptoms and leg weakness. Therefore, in such cases, a high level of suspicion is necessary for accurate and prompt diagnosis and treatment.

Sciatic neuropathy is a rare complication of gynecologic procedures with lithotomy position. Anesthesiologists should be aware of the possible causes and take extreme care to prevent nerve injuries. We report a case of postoperative sciatic neuropathy after a robot-assisted laparoscopic myomectomy, despite following recommended guidelines regarding appropriate positioning. Compressive neuropathy following a prolonged operation should be considered.

The piriformis syndrome is a condition allegedly attributable to compression of the sciatic nerve by the piriformis muscle. Recently, magnetic resonance neurography and electrophysiologic study have helped to diagnose piriformis syndrome. High dose radiotherapy could induce acute and delayed muscle damage. We had experienced piriformis syndrome with fatty atrophy of piriformis muscle after radiotherapy for recurrent cervical cancer.

STUDY DESIGN: A case report. OBJECTIVE: We wanted to present the clinical manifestation and imaging findings of a rare case of acute sciatic nerve palsy with a foot drop similar to lumbar disc herniation developed after sleeping for 8 hours in a sitting position in inebriated condition. SUMMARY OF LITERATURE REVIEW: Sciatic nerve palsy as a complication from being operated in a sitting position have been reported, but here have not been any reported cases of after-sleep sciatic nerve palsy. STUDY SUBJECT AND METHODS: Sixty eight year old male admitted to hospital due to acute onset of right foot drop, subsequent walking difficulty, and numbness of the right calf and foot. Symptoms began after 8 hours of sleeping in a sitting position. Pelvic MRI exam revealed sciatic neuropathy, and also electrophysiological exam revealed sciatic nerve palsy. RESULTS: The subject patient's conditions started improving after 6 weeks and he was able to walk again on his own. CONCLUSION: Sciatic nerve injury by prolonged pressure around the buttocks or posterior thighs, albeit rare, can develop and may cause foot drop, parethesia and sciatica.

PURPOSE: The purpose of this study is to evaluate the clinical results of modified Stoppa approach in acetabular fractures. MATERIALS AND METHODS: Twelve patients who underwent surgery using the modified Stoppa approach for acetabular fractures were enrolled. There were 10 cases of isolated acetabular fracture, two cases of acetabular fracture combined with pelvic ring injury. There were two cases of anterior column fracture, nine cases of both column fracture, and one case of T-type fracture according to Letournel classification. The clinical outcomes were evaluated from Harris hip score (HHS) at postoperative one year and complications. The radiologic result was evaluated according to Matta criteria; anatomical, imperfect, and poor. RESULTS: According to the radiological results, there were eight cases of anatomical, three cases of imperfect, and one case of poor reduction. The average HHS was 82.5 and 10 patients had excellent or good results. The other two patients had poor results due to lumbosacral plexopathy and poor reduction, respectively. The complication included one case of incomplete sciatic nerve palsy, which was recovered at postoperative three months. CONCLUSION: Internal fixation of acetabular fractures using the modified Stoppa approach had satisfactory clinical and radiological outcomes. The modified Stoppa approach can be a useful option for acetabular fractures with appropriate indication and anatomical information.

Sciatic nerve palsy is the most common nerve injury associated with acetabular fracture and dislocation, but femoral nerve injury is known to be very rare because of relative protected position of nerve between the iliacus and psoas muscle, and as far as we know only one report was noted in English about combined femoral and sciatic nerve injury associated with acetabular fracture and dislocation, so we hereby report a case of combined femoral and sciatic nerve palsy associated with acetabular fracture and dislocation.

Nerve palsy as a complication of hematoma following total hip arthroplasty (THA) is a rare development. Although rare, this complication can cause permanent nerve palsy. The authors experienced a case of recovery from sciatic nerve palsy after emergency evacuation of a hematoma. The expanding thigh hematoma was due to anticoagulation treatment for prevention of venous thromboembolism after total hip arthroplasty. After 10 months from the operation, the patient regained complete motor power and leads an ordinary life. The authors would like to emphasize the danger of hematoma following anticoagulation therapy for prevention of venous thromboembolism after total hip arthroplasty.

Rhabdomyolysis is an acute disorder resulting from skeletal muscle injury in which intracellular contents are released into extracellular space and plasma. The condition may result from drug or alcohol abuse, infection, collagen disease or intensive excersice, trauma and longstanding comatous mentality. We report a case of sciatic nerve palsy complicating gluteal compartment syndrome due to rhabdomyolysis.
