INTRODUCTION: The purpose of the study was to determine the surgical outcomes of intramedullary nailing in diaphyseal atypical femoral fractures (AFFs) and to evaluate the clinical outcomes of nail entry modification technique. MATERIALS AND METHODS: We retrospectively reviewed diaphyseal AFFs treated with IMN at nine institutions. In total, 82 patients were included. Surgical outcomes such as complication, union time, and femoral bowing were evaluated. We modified the nail entry of the straight nail from piriformis fossa to the tip of the greater trochanter in the bowed femur and compared the surgical outcomes between the original group and the modification group...

Pain in the coccyx is referred as coccydynia. The pain aggravates in weight bearing i.e. sitting. Total 48 persons with coccydynia diagnosed clinically were recruited and randomly assigned into one of the 3 groups. Experimental group I were treated by stretching of piriformis and iliopsoas muscles, experimental group II were treated by stretching of piriformis and iliopsoas muscles and Maitland's rhythmic oscillatory thoracic mobilization over the hypomobile segments and the conventional group were treated by seat cushioning + Sitz bath + Phonophorosis...

A 12-year-old girl presented with a 1-week history of right hip pain. MRI revealed a lesion in the incompletely fused posterior triradiate cartilage of the right acetabulum with imaging characteristics of an osteoid osteoma. The surgeon requested guidewire placement under CT guidance for lesion drilling. The CT approach was planned to avoid the usual course of the sciatic nerve, and the lesion was successfully removed and confirmed at histology to be an osteoid osteoma. At a follow-up visit, MRI showed no recurrence but demonstrated an abnormal common peroneal nerve from the sciatic notch to the popliteal fossa with denervation oedema in the tibias anterior and peroneal musculature...

We report a case of sciatica that fulfilled the diagnostic criteria for inferior gluteal vein varicosities according to patient history and on magnetic resonance imaging. Since conservative treatment was ineffective, excision-ligation of the varicose vein was performed as recommended in the previous literature. However, pain was only slightly relieved and then aggravated. Reoperation involving wide release and resection of the piriformis outlet was performed. Pain resolved immediately thereafter. We suggest that this case of sciatica resulted from both piriformis entrapment and vein varicosities...

BACKGROUND: The recommended location of graft attachment during sacrocolpopexy is at or below the sacral promontory on the anterior surface of the first sacral vertebra. Graft fixation below the sacral promontory may potentially involve the first sacral nerve. OBJECTIVE: The objectives of this study were to examine the anatomy of the right first sacral nerve relative to the midpoint of the sacral promontory and to evaluate the thickness and ultrastructural composition of the anterior longitudinal ligament at the sacral promontory level...

Exchange nailing has proven to be a reliable surgical technique for the management of aseptic femoral shaft nonunions. Similar to primary intramedullary nail fixation for femur fractures, exchange nailing for aseptic hypertrophic nonunions of the femur relies on successful navigation of the starting point and proper nail trajectory to minimize coronal and sagittal plane deformities. Compared with the supine position, the lateral decubitus position has the advantage of allowing gravity to displace the soft tissue around the piriformis start site to facilitate nail entry...

Terminal hip flexion contributes to increased strain in peripheral nerves at the level of the hip joint. The effects of hip abduction and femoral version on sciatic nerve biomechanics are not well understood. A decrease in sciatic nerve strain will be observed during terminal hip flexion and hip abduction, independent of femoral version. Six un-embalmed human cadavers were utilized. Three Differential Variable Reluctance Transducers (DVRTs) sensors were placed on the sciatic nerve while the leg was flexed to 70° with a combination of - 10°, 0°, 20° and 40° adduction/abduction...

Sciatic nerve injury (SNI) results in neuropathic pain, which is characterized by the excessive Ca(2+) entry, reactive oxygen species (ROS) and apoptosis processes although involvement of antioxidant Hypericum perforatum (HP) through TRPM2 and TRPV1 activation has not been clarified on the processes in SNI-induced rat, yet. We investigated the protective property of HP on the processes in the sciatic nerve and dorsal root ganglion neuron (DRGN) of SNI-induced rats. The rats were divided into five groups as control, sham, sham+HP, SNI, and SNI+HP...

Piriformis muscle syndrome (PMS) is difficult to diagnose by objective evaluation of sciatic nerve injury. Here we report a case of PMS diagnosed by diffusion tensor imaging (DTI) and tractography of the sciatic nerve, which can assess and visualize the extent of nerve injury. The patient was a 53-year-old man with a 2-year history of continuous pain and numbness in the left leg. His symptoms worsened when sitting. Physical examination, including sensorimotor neurologic tests, the deep tendon reflex test, and the straight leg raise test, revealed no specific findings...

BACKGROUND: Antegrade intramedullary (IM) nailing for skeletally immature femur fractures can damage the capital femoral epiphysis blood supply, leading to avascular necrosis (AVN) of the femoral head. Reported AVN rates are 2% for piriformis entry and 1.4% for trochanteric entry. None of previous reports described IM lengthening nails for limb lengthening procedures. We have used self-lengthening telescopic nails with a proximal Herzog bend and standard trochanteric entry for femoral lengthening in children...

BACKGROUND: Modular neck femoral stem (MNFS) for total hip arthroplasty (THA) was introduced to optimize the outcome, but created concerns about pain, elevated blood metal ion levels, and adverse reaction to metal debris such as pseudotumors (PTs), related to corrosion between femoral neck and stem. We compared these outcomes in patients with MNFS or nonmodular femoral stem (NFS) THA. METHODS: Thirty-three patients with unilateral MNFS THA were compared with 30 patients with unilateral NFS THA...
