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...

A 61-year-old woman was admitted with severe hip pain causing immobility and high serum levels of inflammatory markers. The patient had a medical history of diabetes. She had been scheduled to undergo right hip replacement surgery for the treatment of osteoarthritis associated with gradually progressive pain. On admission, an enhanced abdominal computed tomography scan showed an abnormal increase in synovial fluid surrounding the right ilium, with piriformis muscle calcification. Subsequent blood and specimen cultures identified Campylobacter fetus subspecies fetus...

Various techniques for piriformis muscle release have been published previously. However, it is imperative we continue to improve on existing techniques as well as develop new ones that may further optimize outcomes. Therefore, we aimed to describe an endoscopic technique for the release of the piriformis muscle in those with symptoms of sciatic nerve compression. Using the posterolateral portal, we are able to perform a complete release of the piriformis from the greater trochanter and the piriformis fossa with care to protect the external rotators and the sciatic nerve...

INTRODUCTION: Intramedullary nailing (IMN) has become the standard of care for the treatment of most femoral shaft fractures. Different IMN options include trochanteric and piriformis entry as well as retrograde nails, which may result in varying degrees of femoral rotation. The objective of this study was to analyze postoperative femoral version between three types of nails and to delineate any significant differences in femoral version (DFV) and revision rates. MATERIALS & METHODS: Over a 10-year period, 417 patients underwent IMN of a diaphyseal femur fracture (AO/OTA 32A-C)...

Background and purpose - The accuracy of using clinical measurement from the anterior superior iliac spine (ASIS) to the center of the knee to determine an anatomic axis of the femur has rarely been studied. A radiographic technique with a full-length standing scanogram (FLSS) was used to assess the adequacy of the clinical measurement. Patients and methods - 100 consecutive young adult patients (mean age 34 (20-40) years) with chronic unilateral lower extremity injuries were studied. The pelvis and intact contralateral lower extremity images in the FLSS were selected for study...

A fungus with broad spectrum antifungal activity was isolated from the soil in Qinling Mountain, Shaanxi Province, in China. The fungus was identified as Purpureocillium lilacinum based on ITS rDNA gene analysis. The strain, coded as QLP12, showed high inhibition activity on fungal mycelium growth in vitro, especially to Mucor piriformis, Trichothecium roseum, Rhizoctonia solani, and Verticillium dahliae, and its potential for biocontrol efficacy of eggplant. Verticillium wilt disease caused by Verticillium dahliae among 10 fungal species tested was explored...

OBJECTIVE: We previously reported a modified endoscopic medial maxillectomy (modified transnasal endoscopic medial maxillectomy through prelacrimal duct approach [MTEMMPDA]) to resect inverted papilloma (IP), for which the inferior turbinate (IT) and nasolacrimal duct (ND) can be preserved. MTEMMPDA is a safe and effective method to obtain wide, straight access to the maxillary sinus (MS). However, there are few reported cases of patients who underwent MTEMMPDA, and even fewer of patients who underwent partial osteotomy of the apertura piriformis and the anterior wall of the MS...

BACKGROUND: Wallet neuritis is an example of extra-spinal tunnel neuropathy concerning sciatic nerve. Its clinical appearance often gets confused with sciatica of lumbar spine origin. Wallet-induced chronic sciatic nerve constriction produces gluteal and ipsilateral lower extremity pain, tingling, and burning sensation. It was Lutz, first describing credit-card wallet sciatica in an Attorney, surfaced on Journal of American Medical Association (JAMA), 1978; however, the condition has not been well-studied in various other occupations...

PURPOSE: The apparent failure of pudendal nerve surgery in some patients has led us to suggest the possibility of entrapment of other adjacent nerve structures, leading to the concept of inferior cluneal neuralgia. Via its numerous collateral branches, the posterior femoral cutaneous nerve innervates a very extensive territory including the posterior surface of the thigh, the infragluteal fold, the skin over the ischial tuberosity, but also the lateral anal region, scrotum or labium majus via its perineal branch...

INTRODUCTION: The Sparing Piriformis and Internus, Repair Externus (SPAIRE) technique allows a muscle sparing mini-posterior approach to the hip. METHOD: We present in this article a description of an adaptation of the familiar posterior approach (PA) in which the only tendon released is obturator externus. Termed SPAIRE, this muscle sparing technique enables preservation of the piriformis tendon and conjoint insertion of obturator internus and the gemelli. The technical description allows for safe and reliable replication by any surgeon familiar with the posterior approach (PA) to the hip without reliance on additional equipment, and without compromising the ability to convert into a more extensile approach...

PURPOSE: To perform a synthesis of articles addressing the role of stretching on roots in the pathophysiology of radiculopathy. METHODS: Review of relevant articles on this topic available in the PubMed database. RESULTS: An intraoperative microscopy study of patients with sciatica showed that in all patients the hernia was adherent to the dura mater of nerve roots. During the SLR (Lasègue's) test, the limitation of nerve root movement occurs by periradicular adhesive tissue, and temporary ischemic changes in the nerve root induced by the root stretching cause transient conduction disturbances...

Cancer is frequently seen in women of reproductive age. Diagnosis, management of treatment, and safety of the therapeutic approach are particularly important for these patients. Presently described is pain management in a case of pregnancy with malignant mesenchymal tumor. A 23-year-old woman in 30th gestational week presented with severe pain in right hip and back of the right thigh. Piriformis block successfully decreased pain and was followed by pulsed radiofrequency (PRF) to the piriformis muscle. PRF, as a non-neurodestructive method, is a safe and effective method to treat cancer pain in a pregnant patient...
