Abstract

Porous tantalum rod implantation is a novel surgical method that is used to treat avascular necrosis (AVN) of the femoral head (hip). In the present study, the results of core decompression and tantalum rod implantation were compared with non‑surgical treatment for AVN, and the survivorship of the femoral head was evaluated. In total, 60 patients with AVN femoral head were recruited and analysed. Non‑surgical treatment was selected by 30 patients (41 hips), 7 with a Ficat score of I and 23 with a score of II. Non‑surgical treatment included celecoxib, salvia miltiorrhiza and tetramethylypyrazine and a reduction in weight‑bearing activities. Surgical treatment and porous tantalum rod implantation were selected by 30 patients (41 hips), 10 with a Ficat score of I and 20 with a score of II. After follow‑up (average: 33.5 months), patients were evaluated by assessing post‑operative complications, radiology, hip survivorship and Harris hip score. In the surgical group, pre‑operative symptoms were significantly alleviated. No complications, including infection, delayed healing or fractures were reported. Final follow‑up rates of femoral head survivorship were 4.9% in the non‑surgical group and 36.7% in the surgical group. The Harris hip score was significantly improved following surgery when compared with non‑surgical treatment (P<0.05). The results indicated that core decompression and porous tantalum rod implantation are beneficial short‑ and mid‑term treatment methods for AVN of the femoral head.
