Abstract

Abstract:

BACKGROUND: As the number of elder patients become more and more, the number of arthroplasty operations becomes more, but periprosthetic fractures appear nearly 0.1%-5% as the report. The incidence of fractures grows up year by year. According to the part of fracture happened, it may have high incidence of complications and revision operation, and its treatment is also a big problem in orthopedics.
OBJECTIVE: To explore the repair method and effect of periprosthetic fractures after total knee arthroplasty.
METHODS: Nine patients had periprosthetic fractures around the knee joint and visited the Xinjiang Uygur Autonomous Region People’s Hospital from January 2007 to December 2012. There were six cases with femur fractures and three with tibia fractures. All the patients had consultations before operation to make sure the type of the prosthesis we used: PFC Sigma Depuy in three cases, and BIOMET Company’s Vanguard in six cases. From the X-ray, we used Kim Classify for femur fracture and used Felix Classify for tibia fracture. Three cases used locking compression plate. Three cases used intramedullary nail. Three cases used LISS system for internal
fixation. Follow-up was conducted after treatment. New York Hospital for Special Surgery knee score was used to assess knee function. The occurrence of complications was recorded.
RESULTS AND CONCLUSION: All nine patients had osteoporosis, and their wound was healed in one stage. Patients were followed up for 9-34 months. Fractures were healed in all patients in averagely 9.4 weeks. There was no deep vein thrombosis in limbs. No infection or loosening appeared. After repair, New York Hospital for Special Surgery knee score was utilized to assess knee function: excellent in five cases, good in three cases, and average in one case. After repair, early exercise was done in patients, and complications were less. These results indicate that periprosthetic fractures can be healed in one stage, and painless knee joint can be obtained. Suitable fixation manner can be obtained in the clinic according to the type of prosthesis and type of fractures.
