Aims. Various surgical techniques have been described for total hip arthroplasty (THA) in patients with Crowe type III dislocated hips, who have a large acetabular bone defect. The aim of this study was to evaluate the long-term clinical results of patients in whom anatomical reconstruction of the acetabulum was performed using a cemented acetabular component and autologous bone graft from the

Surgical interventions consisting of internal
fixation (IF) or total hip replacement (THR) are required to restore
patient mobility after hip fractures. Conventionally, this decision
was based solely upon the degree of fracture displacement. However,
in the last ten years, there has been a move to incorporate patient

Aims. The optimal management of intracapsular fractures of the femoral
neck in independently mobile patients remains open to debate. Successful
fixation obviates the limitations of arthroplasty for this group
of patients. However, with fixation failure rates as high as 30%,
the outcome of revision surgery to salvage total hip arthroplasty
(THA) must be considered. We carried out a systematic review to
compare the outcomes of salvage THA and primary THA for intracapsular
fractures of the

Several different designs of hemiarthroplasty are used to treat intracapsular fractures of the proximal femur, with large variations in costs. No clinical benefit of modular over monoblock designs has been reported in the literature. Long-term data are lacking. The aim of this study was to report the ten-year implant survival of commonly used designs of hemiarthroplasty. Patients recorded by the Australian Orthopaedic Association National Joint Replacement Registry (AOANJRR) between 1 September 1999 and 31 December 2020 who underwent hemiarthroplasty for the treatment of a hip fracture with the following implants were included: a cemented monoblock Exeter Trauma Stem (ETS), cemented Exeter V40 with a bipolar head, a monoblock Thompsons prosthesis (Cobalt/Chromium or Titanium), and an Exeter V40 with a Unitrax head. Overall and age-defined cumulative revision rates were compared over the ten years following surgery.Aims
Methods
There have been several studies examining the
association between the morphological characteristics seen in acetabular
dysplasia and the incidence of the osteoarthritis (OA). However, most studies focus mainly on acetabular morphological
analysis, and few studies have scrutinised the effect of femoral
morphology. In this study we enrolled 36 patients with bilateral
acetabular dysplasia and early or mid-stage OA in one hip and no
OA in the contralateral hip. CT scans were performed from the iliac
crest to 2 cm inferior to the tibial tuberosity, and the morphological
characteristics of both acetabulum and femur were studied. . In addition, 200 hips in 100 healthy volunteer Chinese adults
formed a control group. The results showed that the dysplastic group
with OA had a significantly larger

Aims. We aimed to quantify the relative contributions of the medial
femoral circumflex artery (MFCA) and lateral femoral circumflex
artery (LFCA) to the arterial supply of the head and neck of the
femur. Materials and Methods. We acquired ten cadaveric pelvises. In each of these, one hip
was randomly assigned as experimental and the other as a matched
control. The MFCA and LFCA were cannulated bilaterally. The hips
were designated LFCA-experimental or MFCA-experimental and underwent
quantitative MRI using a 2 mm slice thickness before and after injection
of MRI-contrast diluted 3:1 with saline (15 ml Gd-DTPA) into either
the LFCA or MFCA. The contralateral control hips had 15 ml of contrast
solution injected into the root of each artery. Next, the MFCA and
LFCA were injected with a mixture of polyurethane and barium sulfate
(33%) and their extra-and intra-arterial course identified by CT
imaging and dissection. Results. The MFCA made a greater contribution than the LFCA to the vascularity
of the femoral head (MFCA 82%, LFCA 18%) and neck (MFCA 67%, LFCA
33%). However, the LFCA supplied 48% of the anteroinferior femoral
neck overall. Conclusion. This study clearly shows that the MFCA is the major arterial
supply to the femoral head and neck. Despite this, the LFCA supplies
