Abstract:
BACKGROUND:Traditional core decompression and al ograft fibula supporting can reduce the stress load within femoral head and improve mechanical properties of femoral head. However, it cannot provide supports for maintaining the stability of five pathological areas fol owing femoral head necrosis. OBJECTIVE:To observe the clinical effect of fan-shaped decompression and al ograft fibula supporting internal fixation in treatment of early femoral head necrosis in adults, taking al ograft fibula grants as the control. METHODS:Forty patients with early femoral head necrosis were randomly divided into treatment group and control group, receiving fan-shaped decompression plus al ograft fibula supporting internal fixation and traditional decompression plus al ograft fibula grafting, respectively. The therapeutic effects in two groups were observed and compared. After treatment, patients were detected by bilateral hip anteroposterior films, Harris scoring and X-ray ARCO staging to evaluate the col apse severity and restoration of necrosis. RESULTS AND CONCLUSION:At the last fol ow-up, Harris scores in the treatment group were significantly higher and the repairing effect was better than control group (P<0.05). In treatment group, 18 hips restored wel (72%) and 7 hips delayed or failed to restore (28%);in control group, 9 hips restored wel (60%) and 6 hips delayed or failed to restore (40%). Our findings indicate that, fan-shaped decompression plus al ograft fibula supporting internal fixation yields a more complete decompression, a higher stability of femoral head and a more reliable supporting, compared with traditional decompression plus al ograft fibula grafting.
