To explore the effect of sequential rehabilitation nursing after vascularized iliac bone flap transplantation for patients with femoral head necrosis.

From January 2019 to December 2020, 39 patients with osteonecrosis of the femoral head who were treated with vascularized iliac bone flap transplantation in the department of orthopedics of 920 Hospital of the Joint Logistic Support Force of the PLA were selected as the observation group and given sequential rehabilitation nursing. From January 2017 to December 2018, 36 patients with osteonecrosis of femoral head treated with vascularized iliac bone flap transplantation were selected as the control group, and routine nursing was given after the operation. Visual analogue scale(VAS), incidence of lower extremity deep vein thrombosis(DVT), and Harris hip score were compared between the two groups by t test and chi square test.

All the 75 patients were followed up for (15±5) months. During the follow-up, there was no further aggravation of femoral head necrosis in the observation group. At the last follow-up, Harris score(t=5.642, P<0.001) and excellent hip rate(χ²=6.445, P<0.05) showed better results in the observation group than the control group. The VAS scores at 24, 72 h and seven days after the operation in the observation group were lower than that in the control group (t=4.178, 8.805, 13.002, all P < 0.05). The incidence of DVT was also lower in the observation group than the control group (χ²=5.271, P<0.05).

Sequential rehabilitation nursing can improve the pain threshold of patients with femoral head necrosis treated by vascularized iliac bone flap transplantation, reduce the pain of affected limb, reduce the incidence of DVT after operation, and promote the recovery of hip function.
