Abstract:

BACKGROUND: To delay the further aggravation of early femoral head necrosis, drilling decompression of the femoral head is a better treatment method. However, traditional trepanation and decompression of the femoral head is traumatic.

OBJECTIVE: To compare the difference in the effect between robot-assisted drilling decompression and traditional surgery for aseptic necrosis of femoral head.


METHODS: Forty patients with aseptic necrosis of the femoral head were included for retrospective comparative analysis. According to the treatment plan, they were divided into two groups. Eighteen cases (26 femoral heads) in the robot group were treated with drilling decompression assisted by robots. Among them, 13 cases (18 femoral heads) were in Ficat stage I and 5 cases (8 femoral heads) were in Ficat stage II. The traditional surgery group consisted of 22 patients (29 femoral heads). Among them, 15 patients (19 femoral heads) were in Ficat stage I and 7 patients (10 femoral heads) in Ficat stage II. Incision, times of intraoperative fluoroscopy, intraoperative blood loss, times of intraoperative puncture and operation time were compared between the two groups. Harris score was used before and 1, 3, and 6 months after operation to evaluate the hip effect.

RESULTS AND CONCLUSION: (1) All cases were followed up for 6 months. (2) Incision, times of intraoperative fluoroscopy, intraoperative blood loss, times of intraoperative puncture and operation time were better in the robot group than in the traditional surgery group (P < 0.05). (3) Harris score was not significantly different 1, 3 and 6 months after surgery in the two groups (P > 0.05). (4) Compared with the traditional surgery, robot-assisted drilling decompression has no obvious advantage in the treatment of aseptic necrosis of the femoral head. However, its operation incision is small; the number of intraoperative fluoroscopy is small; the trauma is small; and the operation is safer and minimally invasive.
