Background: The femur is the most common long bone affected by metastatic carcinoma. We report our experience regarding treatment of metastatic femoral fracture using femoral head prosthesis (FHP) or intramedullary nailing (IM nail) with augmentation by polymethylmethacrylate (PMMA).
Patients And Methods: Thirty-five complete fractures in 33 patients were treated surgically. Metastatic lesions were present in the femoral head to neck region (n=9), trochanteric to shaft region (n=23) and supracondular region (n=3).
Results: Eight out of 9 patients with proximal femoral metastasis reconstructed by FHP were later able to walk outdoors. For the 11 patients with trochanteric metastasis, the short type of gamma nail was used for bony fixation. In two patients the inserted IM nails were broken. All other cases showed excellent clinical outcomes. For the 12 patients with femoral shaft metastasis, the long type of gamma nail was inserted. Nine cases showed excellent clinical outcomes without any serious complications.
Conclusion: FHP is indicated for metastases in the femoral head to neck region. IM nailing is best indicated when the lesion is located in the proximal to mid shaft and the patient's life expectancy is <6 month.

Aseptic loosening (AL) of artificial hip joints is the most common complication following hip replacement surgery. A total of eight patients diagnosed with AL following total hip arthroplasty (THA) undergoing total hip replacement and eight control patients diagnosed with avascular necrosis of femoral head (ANFH) or femoral neck fracture undergoing THA were enrolled. The samples of the AL group were from synovial tissue surrounding the lining/head/neck of the prosthesis, and the samples of the control group were from the synovium in the joint cavity.

Objective: By comparing the hip arthroplasty parameters planned with the AIHIP three-dimensional simulation surgery system, this study analyzes the accuracy of the new femoral-side "shoulder-to-shoulder" artificial anatomical marker positioning method in femoral-side prosthesis implantation and the prevention of leg length discrepancy in hip arthroplasty.
Methods: A retrospective collection of 47 patients who underwent initial total hip arthroplasty at our hospital from August 2020 to December 2022 and met the inclusion and exclusion criteria was used as the study subjects. The average age was 67.

Bone marrow adipose tissue is a distinct adipose subtype comprising more than 10% of fat mass in healthy humans. However, the functions and pathophysiological correlates of this tissue are unclear, and its genetic determinants remain unknown. Here, we use deep learning to measure bone marrow adiposity in the femoral head, total hip, femoral diaphysis, and spine from MRI scans of approximately 47,000 UK Biobank participants, including over 41,000 white and over 6300 non-white participants.

Developmental dysplasia of the hip (DDH) poses significant challenges in both childhood and adulthood, affecting up to 10 per 1000 live births in the United Kingdom and United States. While newborn screening aims to detect DDH early, missed diagnoses can lead to severe complications such as hip dysplasia and early onset osteoarthritis in adults. Treatment options range from less invasive procedures like hip-preserving surgery to more extensive interventions such as total hip arthroplasty (THA), depending on the severity of the condition.

Aims: The purpose of this study was to directly compare the Modular Dual Mobility (MDM) Mobile Bearing Hip System (Stryker, USA) and large femoral heads (LFHs) in revision total hip arthroplasties (THAs) at mid-term follow-up, with specific emphasis on survival free of re-revision for dislocation, any re-revision, dislocation, and the risk of metal-related complications.
Methods: We identified 299 revision THAs performed at a single tertiary care academic institution from March 2011 to July 2014. Aseptic loosening of the acetabular component (n = 65), dislocation (n = 58), and reimplantation as part of a two-stage exchange protocol (n = 57) were the most common reasons for index revision.
