BACKGROUND: Augmentation of the proximal femur with bone cement (femoroplasty) has been identified as a potential preventive approach to reduce the risk of fracture. Femoroplasty, however, is associated with a risk of thermal damage as well as the leakage of bone cement or blockage of blood supply when large volumes of cement are introduced inside the bone. METHODS: Six pairs of cadaveric femora were augmented using a newly proposed planning paradigm and an in-house navigation system to control the location and volume of the injected cement...

Ankylosing spondylitis (AS) is most common in adolescents and the ultimate result is disability, which places a huge burden on patients and society. Therefore, the key to improve the prognosis of AS is the early diagnosis of hip injury. To examine if AS patients whose hip pain is either absent or minimal might already have observable MRI and X-ray hip changes. Clinical and imaging hip data were systematically analyzed in 200 healthy controls (HC) and 300 AS with varying degrees of hip pain. Forty-four patients with early hip osteoarthritis (OA) served as positive imaging controls...

BACKGROUND: Proximal femoral nail antirotation-2 (PFNA-2) has been widely used to treat intertrochanteric fractures with varied outcomes in the previous studies. The entry point of the nail plays an important role in achieving acceptable reduction, stable fixation, and avoiding implant related complications. This study was proposed to determine the optimal greater trochanteric entry point for PFNA-2 in unstable intertrochanteric femur fractures. METHODS: We conducted an observational study on 40 patients with unstable intertrochanteric fracture treated with PFNA-2 implant in a tertiary care hospital...

INTRODUCTION: Total hip arthroplasty in patients with high hip dislocation is a surgically demanding procedure. This is due to the congenital disorder of hip maturation and the resulting anatomical features. The aim of the arthroplasty is implantation of the cup prosthesis in the original centre of rotation, at the same time correcting femoral deformities and reducing the hip joint. INDICATIONS: The indications include advanced osteoarthritis in the secondary acetabulum, existing instability, severe contractures and secondary changes in adjacent joints...

BACKGROUD: The osteotomy of the posterolateral overhanging part (PLOP) of the greater trochanter via posterior approach has been used for the hip arthroplasty for decades with good results. However, the osteotomy method remains undefined and the precise adjacent structures around PLOP have not been reported. The purpose of this study was to present a modified PLOP osteotomy approach and perform a detailed study of the topographic and surgical anatomy of the PLOP. METHODS: The peri-PLOP soft tissue and the bony parameters were measured using 10 cadavers with 20 hips and 20 skeletal hip specimens, respectively...

The impact between acetabulum and femoral neck is another possible mechanism of femoral neck fracture.Direct trauma of the greater trochanter may not be able to fully explain the mechanism underlying femoral neck fracture. In this study, we sought to investigate whether anterior femoroacetabular impingement are associated with femoral neck fractures.A total of 36 patients with femoral neck fracture who had undergone total hip arthroplasty or hemiarthroplasty were included in this study. These patients were divided into 2 groups: labrum tear group and normal labrum group...

Total hip arthroplasty (THA) of Crowe type IV developmental dysplasia of the hip (DDH) is challenging. Although traditional (lateral, posterolateral, and posterior) THA approaches have been used with great anatomic success, they damage periarticular muscles, which are already quite weak in type IV DDH. The recently developed direct anterior approach (DAA) can provide an inter-nerve and inter-muscle approach for THA of type IV dysplasia hips. However, femur exposure with the DAA could be difficult during surgery and it is hard to apply femoral shortening osteotomy...

Approximately 3% of all joint dislocations involve the hip joint, and only 8-10% of these will be anterior. Traumatic anterior open dislocation of the hip is rare in children and prone to be associated with injuries, extensive soft tissue damage, and avascular necrosis of the femoral head. We present a case of a 13-year-old boy who had an open anterior dislocation of the hip with ipsilateral avulsion of the greater trochanter after a tractor wheel crush in an agricultural accident. Additional lesions included a diaphyseal closed fracture of the contralateral femur...

We present a case of a secondary injury to the femoral artery in a geriatric male patient who sustained a pertrochanteric femoral fracture. Six days after closed fracture reduction and intramedullary femoral nailing, the patient presented with persistent hematocrit level drops, femoral swelling and pain. A computed tomography angiography of the femur revealed a perforation of the profunda femoris artery through the dislocated lesser trochanter fragment, and immediate surgical revision was induced. The patient returned to his pre-injury mobilization level without any peripheral vascular or neurological deficiencies...

The modified Dunn procedure enables restoration of the proximal femoral anatomy and normal hip function in patients with slipped capital femoral epiphysis (SCFE). Surgery is indicated in severe SCFE and in hips with a moderate slip angle and impaired function. To prevent further dislocation of the femoral head, the authors recommend non-weightbearing until surgery, since an accurate evaluation of slip stability is not possible in the clinical setting. Only a well-trained orthopedic surgeon with a high level of expertise in hip preservation surgery should perform this procedure...

Frequent repositioning is important to prevent pressure ulcer (PU) development, by relieving pressure and recovering damages on skin areas induced by repetitive loading. Although repositioning is the gold standard to prevent PU, there is currently no strategy for determining tissue condition under preventive approaches. In this study, the peak reactive hyperemia (RH) trends and ultrasonographic (US) features are compared with the tissue condition under histopathological examination to determine the potential use of these features in determining the tissue condition noninvasively...

BACKGROUND: Femoral trochanteric fractures are common among older adults. In the reduction of trochanteric fractures, acquiring the support of the anterior cortex at the fracture site on lateral view immediately after surgery is important. However, even if the cortical support is acquired, postoperative displacement due to the loss of this support often occurs. This study aimed to investigate local stress distribution in several trochanteric fracture models and to evaluate risk factors for postoperative displacement using the finite element (FE) method...
