BACKGROUND: Hip dislocations are a common presentation in the Emergency Department (ED) and require urgent reduction to reduce the risk of avascular necrosis. Over 90% of all dislocations can successfully be reduced in the ED and there is evidence that cases awaiting operative reduction result in significant delays. DISCUSSION: While there is limited data comparing specific techniques, the individual success rates of most maneuvers range from 60-90%. Additionally, each technique has distinct advantages and limitations associated with its use...

Iloprost is a commercially available prostaglandin I2 (PGI2) analogue that is shown to have antithrombotic, vasodilatative and antiproliferative effects. A number of clinical studies have shown that Iloprost can be effective in the management of bone marrow oedema and the treatment of avascular necrosis. The aim of this manuscript is to present our current understanding on the effect of Iloprost on the treatment of these conditions. Areas covered: The authors offer a comprehensive review of the existing literature on the experimental and clinical studies analysing the effect of Iloprost on bone, bone marrow oedema and avascular necrosis...

INTRODUCTION: The Taperloc® Complete femoral stem (Zimmer Biomet, Warsaw, Indiana) builds on the widespread clinical success of the original Taperloc design used since 1982. Enhancements to the Complete design include a lowered caput-collum-diaphyseal (CCD) angle from 138° to 133° for improved offset, optimized neck taper with polished neck flats to increase range of motion, reduced distal geometry to improve proximal canal fill, and gradual off-loading that is the goal of tapered geometry...

RATIONALE: Idiopathic avascular necrosis of the scaphoid or lunate bone are known as Preiser disease and Kienböck disease, respectively. Although there are reports of avascular necrosis involving more than one carpal bone, concurrent idiopathic avascular necrosis of the scaphoid and lunate bones is rare, with only five cases reported in the English literature (including the two herein). Although the optimum treatment for Preiser disease with concomitant Kienböck disease has not been established, our cases underwent closed radial wedge osteotomy based on the evidence of satisfactory outcomes for treating Kienböck disease...

Talus fractures with associated dislocations are rare but have high rates of complications, including avascular necrosis (AVN). Management of these injuries involves urgent surgical reduction and fixation, although there are no definitive data defining an operative time frame for preserving the blood supply and preventing complications. To determine the effect of time to surgical reduction of talus fractures and talus fracture-dislocations on rates of AVN and posttraumatic osteoarthritis (PTOA), we retrospectively reviewed talus fractures surgically managed at a level I trauma center during the 10-year period 2003 to 2013...

Chul Hyun Park, Woo-Chun Lee
We compared the results of proximal chevron osteotomy and double metatarsal osteotomy for hallux valgus with an increased distal metatarsal articular angle (DMAA). From October 2008 to December 2012, first metatarsal osteotomies were performed in 64 patients (69 feet) with symptomatic hallux valgus associated with an increased DMAA. Proximal chevron with Akin osteotomy and lateral soft tissue release was performed in 46 feet (PCO group); double metatarsal osteotomy and Akin osteotomy without lateral soft tissue release was performed in 23 feet (DMO group)...

PURPOSE: Avascular necrosis of the talus is one of the most notable complications associated with talar neck fractures with frequent evolution of the osteonecrosis into a difficult arthrodesis. We tested whether the injection of bone marrow mesenchymal stem cells (MSCs) could improve the repair process of the osteonecrosis. MATERIAL AND METHODS: Forty-five early (without collapse) post-traumatic talus osteonecroses (group 1; study group) were treated between 1995 and 2012 with percutaneous injection of progenitor cells (autologous bone marrow concentrate from the iliac crest)...

We studied three FLT3 ITD acute myeloid leukemia (AML) patients who relapsed after allogeneic haematopoietic stem cell transplantation (alloHSCT) and received multikinase inhibitor (MKI) sorafenib as part of salvage therapy. MKI was given to block the effect of FLT3 ITD mutation which powers proliferation of blast cells. However, the known facts that sorafenib is more effective in patents post alloHSCT suggested that this MKI can augment the immune system surveillance on leukaemia. In the present study, we investigated in depth the effect of sorafenib on the alloreactivity seen post-transplant including that on leukaemia...

Scaphoid non-union affects wrist joint function and is often associated with a predictable pattern of degenerative change. A 30-year-old man presented with a symptomatic 15-year-old right scaphoid fracture with secondary scaphoid non-union advanced collapse of his right wrist. There was no evidence of avascular necrosis. The initial injury was from a fall onto his outstretched hand. We performed a right scaphoid open reduction, internal fixation and iliac crest bone graft. One year after the operation, the patient had good wrist function and grip strength...

About 250000 patients are operated on annually for hip arthroplasty in the USA alone. Of this number, about 10% the cause of their osteoarthritis is the avascular necrosis of the femoral head. But the causes of necrosis are multiple and many of them are still unknown. That is why small advances in etiopathogenesis, diagnosis and treatment of different causes are very important in order to reduce the number of affected patients. It may seem that small changes, studies focused on the details of different diseases do not bring great changes to science, but it is these small changes that end up adding great evolutions in our knowledge...

Dexamethasone (Dex) and other glucocorticoids are widely used to treat serious infections and immunological diseases, however they may cause steroid‑induced avascular necrosis of the femoral head (SANFH). Salidroside (Sal) has demonstrated an anti‑apoptotic effect on neurocytes by activating the phosphoinositide 3‑kinase (PI3K)/protein kinase B (Akt) signaling pathway. In the present study, primary osteoblasts were used in vitro and in rats in vivo to determine the anti-apoptotic effect of Sal on SANFH...

BACKGROUND: Perilunate dislocations and fracture-dislocations are a subcategory of the carpal instability complex. Herein, we report our university hospital experience with this complex injury. The goal of our study was to find predictive factors and quantify the development of arthritis and lunate necrosis. We tried to measure the impact of arthritis on hand function. METHODS: Between January 2000 and December 2014, 21 patients underwent surgery for perilunate dislocations and perilunate fracture-dislocations of the wrist in our tertiary university center...

Dislocation of the major joints of the lower extremities--hip, knee, and ankle--can occur due to motor-vehicle crashes, falls, and sports injuries. Hip dislocations are the most common, and they require emergent management to prevent avascular necrosis of the femoral head. Knee dislocations are uncommon but potentially dangerous injuries that can result in amputation due to the potential for missed secondary injury, especially if they are reduced spontaneously. Isolated ankle dislocations are relatively rare, as most ankle dislocations involve an associated fracture...

Slipped capital femoral epiphysis (SCFE) is a serious orthopaedic hip disease in the adolescent population. It has a prevalence of 10.8 per 100.000 children and usually occurs in children 9-16 years of age. Despite focus on delay of the diagnosis, no improvements have been made. An adolescent complaining of stress-related pain in the hip, groin, thigh or knee should be suspected of having SCFE, until an X-ray has excluded this diagnosis. Delayed diagnosis may have serious consequences in terms of further displacement of the femoral head and risk of increased avascular necrosis...

Introduction: Traumatic dislocation of the hip with ipsilateral fracture neck femur is a rare injury because of the different mechanism of both these injuries. The management of such injuries is a challenge as the chances of nonunion and avascular necrosis of femoral head are very high with fixation methods. We report a case of obturator dislocation of the hip with ipsilateral fracture neck of the femur which was treated with uncemented total hip replacement. Case Report: A 32-year-old male sustained obturator dislocation with ipsilateral fracture neck femur following road traffic accident...

About 1 in 3 people suffer from bone and joint disease, which is a disease of bone and cartilage cells. Osteonecrosis of the femoral head (ONFH) is a typical example of bone and joint disease involving bone cell necrosis. Osteonecrosis of the femoral head leads to the occurrence of premature osteoarthritis of the hip and collapse of the cartilage cells, and there is currently no effective drug treatment available. In order to study the effects of "bone-strengthening pill" (BSP) on the repair of bone and cartilage cells, we investigated the potential effects of the herbal mixture BSP in an animal model of avascular necrosis of the femoral head and in patients...

Case 1: A 33-year-old man with hemoglobin SS (homozygous hemoglobin S) disease presents for his regular clinic visit. He had 6 hospital admissions for pain over the past year. He also has avascular necrosis of the right hip. He takes daily hydroxyurea with hematologic changes indicative of compliance. He also takes morphine sustained release twice daily and morphine immediate release every 6 hours as needed for pain. He feels that more optimal pain control at home would help him reduce his number of hospital admissions in the upcoming year and improve his daily functioning at home...

BACKGROUND: Long standing nonunion of the lateral humeral condyle (LHC) usually results in elbow pain and instability with progressive cubitus valgus and tardy ulnar neuritis. Surgical treatment of long standing nonunion is still a controversial issue due to the reported complications, such as stiffness, loss of elbow motion, and avascular necrosis of the LHC fragment. In this study, we reported the outcomes of treatment of cubitus valgus deformity in long standing nonunion of the LHC in children treated with combined triple management (fixation of the nonunion site, dome corrective osteotomy, and anterior transposition of ulnar nerve) through a modified para-triceptal approach...

Objective This study aimed to assess the principal risk factors that could lead to the most common long-term complications of slipped capital femoral epiphysis, such as avascular necrosis, chondrolysis, and hip impingement. Methods We conducted a single-centre, retrospective study and evaluated patients (70 patients, 81 hips) who were treated for slipped capital femoral epiphysis from 2010 to 2015 and who underwent pinning. We measured the severity of displacement radiologically using the Southwick angle. Postoperative radiographs were evaluated for the most frequent long-term complications of avascular necrosis (AVN), chondrolysis, and femoral acetabular impingement (FAI)...
