Abstract

Background: This study assessed the mortality and complications of hip fractures using in-patients aged 20-40 years from a nationwide population database in Taiwan.

Methods: Subjects were selected from Taiwan's National Health Insurance Research Database for the period 2000-2008, and these subjects were followed up until the end of 2010. A total of 5,079 (3,879 male and 1,200 female) subjects were admitted for the first time with primary diagnosis of hip fracture and treated with operation. We calculated the long-term overall survival rate and complication-free rate. We also assessed the risk factors for mortality and complications.

Results: The 1-month, 3-month, 6-month, 1-year, 2-year, 5-year, and 10-year complication-free rates were 98.3%, 96.2%, 94.5%, 86.8%, 80.4%, 75.3%, and 73.5% for the entire cohort, respectively. The 10-year survival rates were 93.3%, 91.8%, and 94.5% for total cases, trochanteric fracture, and cervical fracture, respectively. The 10-year complication-free rates were 73.5%, 80.5%, and 67.3% for total cases, trochanteric fracture, and cervical fracture, respectively. The risk factors for overall death were male, older age, and greater number of Charlson comorbidity index (CCI) comorbidities. The risk factors for complication were cervical fracture, and greater number of CCI comorbidities. Complications resulted in 42.83% of patients receiving internal fixation implants or prothesis removal and 2.01% underwent conversion to revision arthroplasty during follow-up.

Conclusions: The overall 10-year survival rate in hip fracture patients aged 20-40 years in Taiwan was over 90%. The 10-year complication-free rates were around 70%. Preventing the occurrence of severe complications after hip fracture among young adults is an important public health issue that warrants greater attention.
