Why do subchondral cysts occur at the medial aspect of the femoral head in hip dysplasia?

Introduction: Osteoarthritis in dysplastic hips should develop from the lateral side of the acetabulum and the femoral head just below. However, the existence of subchondral cysts located more on the medial side contradicts the weight-loading theory. The aim of this study was to confirm the presence of medial cysts at the femoral head and to investigate the relationship between medial cysts and injuries of the ligamentum teres in hip dysplasia.

Reliability of the acetabular reconstruction technique using autogenous bone graft from resected femoral head in hip dysplasia: Influence of the change of hip joint center on clinical outcome.

Introduction: The previous studies have not reached on consensus as to the outcome of acetabular reconstruction with autogenous bone graft for dysplastic hips, especially in severe cases such as Crowe type IV. The current study aimed to determine the survivorship of the arthroplasty and the grafts as well as the change of hip joint center averagely 9.8 years (range, 5-19) after cementless total hip arthroplasty.

Aspergillus Septic Arthritis of the Hip in an Immunocompetent Middle-aged Female with Undiagnosed Recurrent Pulmonary Aspergillosis.

We present a case of Aspergillus septic hip arthritis in an immunocompetent patient with undiagnosed recurrent pulmonary aspergillosis who underwent arthroscopic surgery. Biopsy specimens of synovium revealed fungal hyphae, confirming Aspergillus infection. Aspergillus septic hip arthritis can occur in immunocompetent patients, and arthroscopy can be a noninvasive surgical option in these cases.

Periprosthetic fractures of the distal femur following total knee arthroplasty: even very distal fractures can be successfully treated using internal fixation.

Purpose: We treat periprosthetic fracture of the distal femur above total knee arthroplasty using single or double plating and the minimally invasive plate osteosynthesis (MIPO) technique. Here, we report the results of using this operative treatment and our analysis of whether very distally extended fractures can also be successfully treated using internal fixation.

Methods: We retrospectively reviewed 32 periprosthetic distal femoral fractures.

The effects of lignan-riched extract of Shisandra chinensis on amyloid-β-induced cognitive impairment and neurotoxicity in the cortex and hippocampus of mouse.

Ethnopharmacological Relevance: The fruits of Schisandra chinensis (Trucz.) Baill. (Schisandraceae) which have been used as a tonic especially for kidney yin deficiency in Chinese traditional medicine are recently receiving attention for its preventive activity on age-related neurodegenerative diseases.
