BACKGROUND: The gluteus medius (GMED) affects hip function as an abductor. We evaluated muscle volume and degeneration of the GMED by using CT-based analysis and assessed factors that affect hip abductor strength in patients with unilateral hip osteoarthritis (OA). METHODS: We examined clinical and imaging findings associated with hip abductor strength in consecutive 50 patients with unilateral hip OA. Hip abductor muscle strength and Harris hip score (HHS) were assessed...

INTRODUCTION: Non-traumatic limping is a common reason for consultation in paediatric emergencies. Although transient synovitis of the hip (TS) is the most frequent diagnosis, there are cases of limping secondary to serious pathologies. The aim of this review is to describe the variables related to non-traumatic limp that come to the paediatric emergency department to establish the best management protocol, making the most of resources and speeding up emergency care. MATERIAL AND METHOD: A prospective study was conducted, selecting all children less than 15 years old who consulted aspaediatric emergencies for non-traumatic limping during the 2014...

INTRODUCTION: Trans arterial embolization (TAE) can stem uncontrolled bleeding associated with pelvic fractures, but is associated with potential complications. This study investigated and compared the early to midterm complications in two patient cohorts: one who did and one who did not undergo TAE. METHODOLOGY: The results of 14 patients who underwent TAE in the resuscitation phase, and then had their pelvic fractures managed non-operatively, the study group (Group 1), were compared with those of a control group (Group 2) of 14 patients matched for age, sex, injury and management, that did not undergo TAE...

BACKGROUND: Extensive tearing of the gluteus muscles (spontaneous or subsequent to hip arthroplasty) is difficult to treat. We are carrying out osseous fixation with securement of the suture anchor by a nonresorbable collagen patch. The objective of this study is to examine the follow-up data of 30 patients and to assess whether the clinical outcomes depended on the extent of the fatty degeneration of the gluteus medius. METHODS: Thirty patients (28 female and 2 male) with a mean age of 76...

Bellini Duct Carcinoma (BDC) of the Kidney is a rare type of Renal Cell Carcinoma. It usually presents with features of local advancement or metastasis and rarely diagnosed incidentally. We present a case report of a young man who was found to have BDC of the Right Kidney following presentation with an iliac bone tumour. A 40 year old man presented to the Orthopaedic outpatient clinic on account of right sided pelvic pain and limping following a trivial fall at home. There was no antecedent history of loin pain, loin mass or haematuria...

The surgical treatment of septic non-union is challenging and carries a high failure rate. Bone defect management and fracture site stabilisation are key treatment objectives. We report the case of a 75-year-old woman who underwent intercalary endoprosthetic reconstruction of a large tibial defect due to septic non-union after two previous treatment failures. The two-stage procedure involved extensive excision of infected tissues and implantation of an antibiotic-loaded cement spacer followed by insertion of an intercalary endoprosthesis...

We report here the case of a 3-year-old patient, who presented a left limp and a total refusal of walking, without any traumatism. Clinical examination revealed a significant pain in the left leg with a limit to the limiting mobilization. Acute phase reactants were slightly elevated. Based on the hip ultrasound, acute transient synovitis of the hip was diagnosed. Following persistent complaints, a hip plain radiography was performed, showing a discreet reshuffle at the right ischiopubic branch. The MRI of the hip revealed a discrete T2 high intensity centered on the right ischiopubic synchondrosis (IPS), corresponding to a Van Neck-Odelberg osteochondrosis...

The NOD-like receptor (NLR) family pyrin domain-containing protein 3 (NLRP3) inflammasome is implicated in the pathogenesis of multiple diseases including neuroinflammation associated with multiple sclerosis (MS). However, the extent to which NLRP3 has a pathobiological role in MS-associated central neuropathic pain (CNP) is unknown. Hence, the present study was designed to address this issue using an optimised relapsing-remitting experimental encephalomyelitis (RR-EAE)-mouse model of MS-associated neuropathic pain...

Hip dysplasia, when significant, is effectively treated with periacetabular osteotomy. There have been good results reported with hip arthroscopy when dysplasia is mild. However, when dysplasia is significant, hip arthroscopy with labral repair alone has led to poor results and even rapid decline to end stage arthritis. Staged hip arthroscopy and periacetabular osteotomy would potentially treat the labral lesion and correct the underlying bony abnormality that resulted in the labral pathology. Such a staged treatment plan should help prevent progression to degenerative joint disease...

Ewing's sarcoma is a common malignant bone tumor seen in 5-15 years age group. It often arises from diaphysis of long bones. Ewing's sarcoma arising from the ilium is very rare, and it has an unfavourable prognosis. We present a rare case report of Ewings sarcoma of ilium with no metastasis in a two and a half year old boy, who was treated with neoadjuvant chemotherapy followed by surgical excision of the tumor and reconstruction using allograft from the femoral head fixed with multiple k-wires and screw. The patient is disease free at one year follow up and the allograft has taken the shape of growing ilium and excellent functionality and gait with minimal limp...

Hip joint instability can be secondary to congenital hip pathologies like developmental dysplasia (DDH) or acquired such as sequel of infective or neoplastic process. An unstable hip is usually associated with loss of bone from the proximal femur, shortening, abnormal gait, and pain. Many authors have suggested proximal femoral valgus osteotomy for the treatment of unstable hip joints. Ilizarov modified this technique and performed a double-level osteotomy. In addition to proximal femoral valgus extension osteotomy, he introduced a distal femoral varus osteotomy which would lead to limb lengthening and correction of mechanical axis of the leg...

INTRODUCTION: Primary synovial chondromatosis (SC) is a disease of the synovium occurring in the third to fifth decade of life with the peak incidence in the fifth decade and commonly involves the knee in 50% cases. The diagnosis of SC is primarily radiological and intraoperative. Primary SC of the hip is rare, and their prevalence is not known. CASE REPORT: A 7-year-old female child presented with pain and limp left hip for 6 weeks. She had a stiff hip gait. Clinical examination revealed a fixed abduction, flexion deformity, and restricted internal rotation with apparent lengthening of 2 cm...

BACKGROUND: Posteromedial and greater trochanteric fragments are a major cause of telescoping and medialization of the femoral shaft in an unstable intertrochanteric fracture. This leads to significant limb shortening, fracture collapse in varus position and implant failure, which can be prevented by trochanteric wiring in addition to dynamic hip screw (DHS) fixation. The purpose of our study is to assess the outcomes of DHS augmented with trochanteric wiring in unstable type A2 intertrochanteric fractures...

Kohler's disease is rare cause of foot pain and limping in the pediatric population. The exact etiology of Kohler's disease is unknown. It usually presents as sudden and unexplained foot pain and limping. We report a case of a 5-year-old male who presented to the Pediatric Emergency Department with foot pain and inability to bear weight for two days after overactivity and acute foot injury. The patient was eventually diagnosed with Kohler's disease (avascular necrosis of the navicular bone). Although Kohler's disease is not very common, it should be considered in the differential diagnosis of foot pain in the pediatric population, as it may prevent unnecessary tests and treatments...

A 4-year-old female was referred to pediatric orthopedic surgery for left leg pain and limping for 3 months following a motor vehicle collision. Recently, the patient's mother had noted left knee swelling and dragging of the left leg when walking. Past medical history was significant for hip dysplasia with slight leg length discrepancy. The patient was otherwise healthy. Physical examination was remarkable for left pre-patellar soft tissue fullness with normal range of motion. There was no warmth or tenderness...

INTRODUCTION: To the best of our knowledge, there has been no report regarding rheumatoid arthritis associated with spinal neuroarthropathy and combined double-level isthmic spondylolisthesis. Here, we report a rare case of spinal neuroarthropathy with double-level isthmic spondylolisthesis in a rheumatoid arthritis (RA) patient. A 56-year-old female patient under medical treatment for RA during the last 13 years presented aggravating radiating pain to her right lower extremity and a limping gait developed 4 months ago...

Conventional kinesin (kinesin-1) can walk on microtubule filaments in an asymmetric hand-over-hand manner, exhibiting a marked alternation in the mean dwell time in successive steps. Here, we study computationally the asymmetric stepping dynamics of the kinesin-1 homodimer, revealing its origin and providing quantitative explanations of the available experimental data. The alternation in the mean dwell time in successive steps arises from the alternation in the mechanochemical coupling ratio, which is in turn caused by the alternation in the slight variation of the stretched neck linker length...

When new motor learning changes the spinal cord, old behaviors are not impaired; their key features are preserved by additional compensatory plasticity. To explore the mechanisms responsible for this compensatory plasticity, we transected the spinal dorsal ascending tract before or after female rats acquired a new behavior-operantly conditioned increase or decrease in the right soleus H-reflex-and examined an old behavior-locomotion. Neither spinal dorsal ascending tract transection nor H-reflex conditioning alone impaired locomotion...
