Minimally invasive treatment of geriatric and osteoporotic femur fractures with polyaxial locking implants (NCB-DF®)

Periprosthetic femur fractures in elderly patients are a challenging surgical procedure. The aim of this study was a prospective evaluation of minimally invasive implantation of non-contact bridging (NCB-DF®) plates. A total of 30 osteosynthesis procedures in 29 patients (average age 76 years and me...

Description
Summary:Periprosthetic femur fractures in elderly patients are a challenging surgical procedure. The aim of this study was a prospective evaluation of minimally invasive implantation of non-contact bridging (NCB-DF®) plates. A total of 30 osteosynthesis procedures in 29 patients (average age 76 years and mean ASA 2.9) with complex femur fractures were registered, 19 fractures were periprosthetic and osteoporosis was present in 17 bones. In 25 patients a minimally invasive percutaneous procedure was performed using a standardized technique. An x-ray examination and clinical follow-up were performed after 6, 12 and 24 weeks. The early complications (14% in total) included 1 plate breakage after 16 weeks as well as 3 minor revisions for screw length correction. The x-ray follow-up after 24 weeks showed a secondary extension deficit of 10° and 15° in the knee joint in 2 patients, respectively. The NCB-DF® implantation using a standardized minimally invasive technique in periprosthetic femur fractures is a safe alternative in elderly patients. In this very sensitive population the early revision rate within the first 24 weeks is noticeable lower compared to similar procedures.
