The Early Result of Cementless Arthroplasty for Femur Neck Fracture in Elderly Patients with Severe Osteoporosis / 대한고관절학회지

PURPOSE: The purposes of the current study were to assess the early results of cementless hip arthroplasty (HA) for femoral neck fractures in elderly patients with severe osteoporosis and to compare the clinical outcomes between those who underwent total HA (THA) or bipolar hemiarthroplasty (BHA). MATERIALS AND METHODS: From April 2011 to May 2012, we performed 87 cementless HAs for displaced femoral neck fractures in elderly patients (> or =65 years) with severe osteoporosis. Among them, we studied 70 hips that were able to be followed-up for >24 months. Of these, 34 underwent THA and 36 underwent BHA. Clinical results were evaluated using the Harris hip score (HHS), Koval classification, and radiographs. RESULTS: Only one instance of femoral stem loosening was observed. Additionally, no dislocations were observed and no revision surgeries were required. The mean changes in the functional items of the HHS scores were 2.8 and 5.2 for those who underwent THA and BHA, respectively (P<0.05). According to the Koval classification used for the ambulatory status analysis, the mean perioperative change in the grade was 0.8 (0-4), with no significant differences noted between the THA and BHA groups. CONCLUSION: The early results of cementless HA for femur neck fractures in elderly patients with osteoporosis were satisfactory, and THA was found to have a functional advantage over BHA.

Giant Intramuscular Lipoma in the Back after a Blunt Trauma: A Case Report

STUDY DESIGN: Case report. OBJECTIVES: To report a case of a giant intramuscular lipoma after a blunt trauma. SUMMARY OF LITERATURE REVIEW: Lipomas are the most frequent benign tumor of the mesenchymal tissue. Although the etiopathogenesis is not complete understood yet, it is known that lipoma develope with a 1% rate after traumas in the related localizations. Traumata induce hematoma and initiates inflammatory reactions in fatty tissue and can trigger the development of lipoma. MATERIALS AND METHODS: 2 years after a blunt trauma a 56years male patient developed a back mass. A massive lipoma was confirmed clinical and radiological. RESULTS: A total excision was performed and the result was histopathologic confirmed. CONCLUSIONS: Patients who develop hematoma after a trauma need a close lipoma progress observation which decrease the invasive treatment of post-trauma hematoma.
