The Femoral Head Edema Zone: A Novel Classification Scheme to Better Predict Osteonecrosis Progression
This study proposed a new classification, the Edema Zone classification, that uses Magnetic Resonance Imaging (MRI) images to grade the extent of edema in osteonecrosis of the femoral head (ONFH). The purpose of the study was 1) to examine how the Edema Zone classification compared to the Japanese Investigation Committee (JIC) classification’s prognostic ability for early conversion to total hip arthroplasty (THA), and 2) to determine how accurately and reliably the Edema Zone classification performed as a classification system.
Does running ruin your knees? And how old is too old to start?
You've probably heard that running is tough on your knees—and even that it can cause long-term damage. But is this true?
A patient's own cartilage cells may be the key to promoting healing after hip surgery
In their study published in the journal Archives of Orthopaedic and Trauma Surgery, the research team collected cartilage removed during hip surgeries.
Hip Replacement Dislocation
Among the most frequently seen complications of hip replacement surgery is dislocation of the hip replacement. Hip replacement dislocations occur in about 4% of first-time surgeries and about 15% of revision hip replacements. This complication is uncommon, but it does occur—sometimes in unforeseen circumstances.
Retrospective Review of Outcomes of Total Hip Arthroplasty in Developmental Dysplasia of the Hip in Adults
Developmental dysplasia of the hip (DDH) is a major cause of hip arthritis in young adults. Total hip arthroplasty (THA) is an effective treatment for DDH, but few studies have examined mid- (5 to 10 years) to long-term (>10 years) outcomes. This study reports the long-term survivorship, clinical, and radiographic outcomes of THA in DDH patients.
