Abstract:

BACKGROUND: With the rapid growth of hip arthroplasty, the number of periprosthetic femoral fractures is increasing yearly. Because most of patients are older adults complicated with severe osteoporosis, the treatment is difficult, which is a challenge for clinical joint surgeons.

OBJECTIVE: To evaluate the curative effectiveness of allogeneic cortical bone plate combined with locking plate for Vancouver type B1 and C osteoporotic periprosthetic femoral fractures after hip arthroplasty.
METHODS: Clinical data of 13 patients with Vancouver type B1 and C osteoporotic periprosthetic femoral fractures after hip arthroplasty at Quanzhou Orthopedic-Traumatological Hospital of Fujian University of Traditional Chinese Medicine between August 2014 and July 2017 were collected. All patients were treated with allogeneic cortical bone plate combined with locking plate, also with anti-osteoporosis treatment. The joint function was assessed by Harris hip score. The fracture and allogenic bone plate healing, prosthesis and internal fixation position, and prosthetic loosening were evaluated by X-ray.
RESULTS AND CONCLUSION: (1) The follow-up time was 12-46 months. (2) The Harris hip score at postoperative 6 months was significantly higher than that at 1 month postoperatively (t=-13.38, P=0.000). The score at last follow-up was significantly higher than that at 6 months postoperatively (t=-5.59, P=0.01). (3) All fractures were healed at 6 months after operation, no loosening of prosthesis or internal fixator was found, bone plate of allograft healed with host bone, and different degrees of modeling were observed at the last follow-up. All patients could walk painlessly. (4) These results indicate that allogeneic cortical bone plate combined with locking plate for Vancouver type B1 and C osteoporotic periprosthetic femoral fractures after hip arthroplasty shows good clinical efficacy.
