Abstract:
Objective:To explore the surgical techniques in posterolateral mini-incision total hip arthroplasty and clinical effcacy.
Methods:A total of 94 patients (98 hips) had posterolateral mini-incision total hip arthroplasty, from December 2006 to December 2008, and were randomly divided into a posterolateral mini-incision total hip arthroplasty group (Group A) and a conventional group of posterolateral incision for total hip arthroplasty (Group B). Forty-nine patients (50 hips) in Group A had posterolateral small incision total hip arthroplasty [26 males, 23 females, between 37.0 and 95.0 years (average 68.9 years), body mass index (BMI) between 20.3 and 29.7 (average BMI 25.4)]. Forty-ifve patients (48 hips) in Group B had the conventional posterolateral incision [27 males, 18 females, between 45.0 and 92.0 years (average 69.7 years), BMI between 18.7 and 34.1 (average BMI 26.9)]. The incision length, blood loss, drainage, operation time, and postoperative Harris scores were compared between the 2 groups.
Results:The incision length was 6.0~10.5 (average length 7.4) cm, average blood loss was 387.6 (140.0~1000.0) mL, average drainage was 143.1 (63.0~375.0) mL, average blood transfusion was 77.6 (0~400.0) mL, average operation time was 84.6 (63.0~130.0) min, and vitalock abduction angle imaging after the operation was 41.6° (averagely 38.0°~57.0°) in Group A. The incision length was 15.0~23.0 (average length 20.0) cm, average blood loss was 513.1 (210.0~1350.0) mL, average drainage was 152.3 (70.0~520.0) mL, average blood transfusion was 142.2 (0~800.0) mL, average operation time was 84.0 (71.0~115.0) min, and postoperative radiographic acetabular cup abduction angle was 42.3° (37.0°~54.0°) in Group B. The follow-up showed that the prosthesis of the 2 groups was in a good position, Harris score was significantly improved with no complications after total hip arthroplasty in the 2 groups.
Conclusion:With the correct selection of indications and adept operation skills and other circumstances, posterolateral mini-incision total hip arthroplasty may do little damage to the soft tissue with a small scar on the skin. The imaging evaluation after the operation and the Harris score show no difference between the 2 groups. Patients are satisfied with their joint function and postoperative recovery.
