Abstract:

BACKGROUND: Traditional posterolateral bipolar prosthetic replacement has a large incision and needs to cut the external rotator muscles, and the rehabilitation time is long. SuperPATH has a small incision, is minimally invasive and articular capsule is retained, which can accelerate the rehabilitation, but needs expensive special equipments and prosthesis. It is feasible to popularize the modified artificial bipolar femoral head through SuperPATH approach.

OBJECTIVE: To compare the curative effectiveness between SuperPATH approach and posterolateral approach with artificial bipolar femoral head, and to investigate the surgical technique and efficacy of modified artificial bipolar femoral head through SuperPATH approach in the treatment of senile femoral neck fracture.
METHODS: Sixty-two patients with senile femoral neck fracture admitted from March 2015 to June 2017 were randomly divided into trial (n=30) and control (n=32) groups. The trial group was treated with advanced instruments, conventional bipolar femoral head using SuperPATH approach, and the control group was treated with conventional bipolar femoral head by posterolateral approach. The length of incision, operation time, intraoperative blood loss, change in hemoglobin, ambulation time, Visual Analogue Scale score and Harris Hip Score were compared to evaluate the curative efficacy.
RESULTS AND CONCLUSION: (1) All patients were followed up for 10-38 months. (2) There was a significant difference in the incision length, intraoperative blood loss, hemoglobin before and after operation, ambulation time, Visual Analogue Scale score at 1 week postoperatively, and Harris Hip Score at postoperative 1 and 3 months between two groups (P < 0.05), and the trial group was better than the control group. (3) The operation time in the trial group was significantly longer than that in the control group (P < 0.05). (4) There was no significant difference in the Visual Analogue Scale score at 3 months postoperatively and Harris Hip Score at postoperative 6 months between two groups (P > 0.05). (5) These findings indicate that after the improvement, the common bipolar femoral head replacement performed by SuperPATH approach in the treatment of senile femoral neck fracture has advantages of smaller incision, less trauma and less blood loss compared with the posterolateral approach, which alleviate postoperative pain and shorten hospitalization time. Therefore, it is recommended in clinical practice.
