ABSTRACT
BACKGROUND: Appropriate treatment of osteonecrosis of femoral head (ONFH) remains challenging. OBJECTIVES: Here, we report the results of treating these patients with auto-corticocancellous bone graft from iliac crest to overcome the need for early total hip arthroplasty (THA). PATIENTS AND METHODS: There were 132 hips (96 patients) with ONFH. Association Research Circulation Osseous (ARCO) type II and III underwent auto-corticocancellous bone grafting from the iliac crest in the current prospective study. Before the operation and in the final postoperative visit, the pain intensity using visual analogue scale (VAS), range of hip motions and Harris hip score (HHS) were determined and compared. Patients were followed for 48.5 ± 17.9 months. RESULTS: The shape of head and the joint space were preserved in 120 hips (90.9%). There were 12 hips in which the disease progressed to grade IV and resulted in THA in 10 of them. The pain intensity significantly decreased (6.3 ± 4.1 vs. 1.4 ± 2) and HHS (35.8 ± 15.3 vs. 79.5 ± 16.2) and range of motion (ROM) significantly improved after the operation (P < 0.001). CONCLUSIONS: Necrotic bone removal and filling the femoral head cavity with auto-corticocancellous bone graft from iliac crest is an effective femoral head preserving method in treating patients with precollapse stages of ONFH and preventing the need for early THA, especially in young active populations.
ABSTRACT
BACKGROUND: Epidemiologic differences among various fracture sites and within different populations are important as they imply different cultures and lifestyles in each region. One of these fractures is the tibial shaft fracture. Rather few epidemiological studies have been undertaken on this injury. This study was designed to provide an update on various aspects of tibial shaft fractures during 1999-2006 in a referral educational orthopedic center in Iran. MATERIAL/METHODS: The charts of 854 adult patients were evaluated in a cross-sectional study. All the patients were examined and the results were registered. The collated information was classified along with descriptive statistical analysis. RESULTS: The highest frequency of these fractures was seen in the 20-30 year age group in both genders, and women had a higher rate than men in people aged > or =50 years old. The most common cause of fractures was road traffic accidents; 54% of all injuries were closed fractures and 46% were open. The most frequent fracture pattern was comminuted and the fewest were segmented and with butterfly fractures. The most noticeable complication early after treatment was infection and those during at least one year follow-up were pain, nonunion, and delayed union. CONCLUSIONS: The peak frequency of tibial shaft fractures in Iran was one decade higher than in European populations and in those > or =50 years old the rate was higher in women, which was two decades lower than the mentioned populations. Furthermore, in this study in addition to high-energy trauma, low-energy trauma also had a great role.
