Analysis Of The Difference Of Short-term Curative Effect Between The SuperCap Approach And The Posterolateral Approach To Artificial Femoral Head Replacement For Older Adults With Femoral Neck Fracture

Objective: To examine the short-term effectiveness of the SuperCap approach in comparison to the posterolateral approach,after artificial femoral head replacement for femoral neck fracture among older adults.Methods: The sample was drawn from patients aged 65 and older admitted between June 2018 and December 2020 because of femoral neck fracture（N = 90）.Half of the patients were assigned to the SuperCap group（Group A,n = 45）,and the other half were in the posterolateral group（Group B,n = 45）.A group of licensed physicians performed artificial femoral health replacement using the same biological type BE femoral stem+metal femoral health from Chun Li in both groups.The time to get out of bed and the incidence of postoperative complications were compared between the two groups.The Harris Hip Function Score（HHS）,VAS（Visual Analogue Scale）,and Mini Mental State Examination（MMSE）were used to record and score the patients’ hip joint level,pain perception,and cognitive level at multiple time points after the surgery.There was no statistically significant difference in age,gender,weight,and preoperative conditions between the paired cases from both groups.Results: The time to get out of bed after surgery in the SuperCap group was earlier than that in the posterolateral group（t = 3.497,P < 0.05）.The Harris scores of the SuperCap group on the 2nd and 7th day after surgery were higher than those of the posterolateral group（t = 3.202 and 3.461,P < 0.05）.There was no statistically significant difference between the Harris scores of the preoperative and the 30 th day after surgery（t = 1.167 and 0.673,P > 0.05）.The VAS scores at 2 h,8 h,and 24 h in the SuperCap group were lower than those in the posterolateral group（t = 2.199,3.697,and 4.519,P < 0.05）.There was no significant difference in VAS score between the two groups at 48 h after surgery（t = 0.957,P > 0.05）.The MMSE score at 8 h after operation in the SuperCap group was significantly higher than that in the posterolateral group（t = 2.274,P < 0.05）,and there was no significant difference in MMSE scores before operation and one day after the operation（t = 1.729,0.419,P >0.05）.The probability of postoperative complications（sciatic paralysis,periprosthetic fracture,and delirium）between the two groups was not statistically significant（?2= 1.047,0,0.714,P > 0.05）.Conclusion: The SuperCap approach can improve early postoperative hip function,reduce pain,accelerate cognitive function recovery after anesthesia.The approach can lead to rapid recovery for older patients with femoral neck fracture from artificial femoral head replacement surgery.
