Abstract

This prospective study compares a mini-incision technique and traditional posterior approach for total hip arthroplasty (THA). Thirty-three patients who had undergone a mini-incision THA were matched by diagnosis, gender, average age, and preoperative Harris Hip Score (HHS) to 33 patients who had undergone THA using the traditional posterior approach. The average length of the incision for group 1 was 11.7 cm (range, 7.3–13.0) and for group 2 was 20.2 cm (range, 14.8–26.0). At the 3-month follow-up, patients in the mini-incision group had significant improvement in limp (P<.05) and ability to climb stairs (P <.01) compared with the traditional group. At the 6 month follow-up, the mini-incision group was significantly better in terms of limp (P <.05), distance walked (P<.001), and stairs (P < 0.001). There was no significant difference between groups for pain, function, or range of motion at the 1-year follow-up examination. Copyright 2003, Elsevier Science (USA). All rights reserved.

Materials and methods

The mini-incision surgical technique was first used for primary THA in October of 1998. One hundred twenty-one patients with 137 hips underwent surgery using this technique. Thirty-three patients (35 hips; group 1) were selected of 121 patients who had undergone a mini-incision THA matched by diagnosis, gender, average age, and preoperative Harris Hip Score (HHS) [13] to 33 patients (35 hips; group 2) of 120 patients who had undergone THA using the traditional posterior approach. The same

Surgical technique

The mini-incision surgical approach used in our study is a modification of the traditional posterior approach (Moore). However, the landmarks for initial skin incision varies significantly. Moore's incision starts approximately 10 cm distal to the posterior superior iliac spine and extendes distally and laterally parallel with the fibers of the gluteus maximus to the posterior margin of the greater trochanter. The traditional incision is then directed distally 10 to 13 cm parallel with the

Results

The average length of the skin incisions for group 2 (traditional posterior approach) measured 20.2 cm (range, 14.8–26.0). For group 1 (mini-incision), the skin incision averaged 11.7 cm (range, 7.3–13.0) (P<.001). The average surgical time was 2 hours for the mini-incision group and 1 hour and 40 minutes for the traditional approach. The preoperative plan for each cup position was 45° of abduction and 20° of flexion. Acetabular cup alignment for both groups was within 5° of the preoperatively

Discussion

We are aware of no clinical data in the literature comparing the functional results of mini-incision with those of the traditional posterior approach for THA with the navigation system. Wright, Crockett, and Sculco [21] described the minimal posterior approach for THA and found that primary THA in selected patients can be performed safely and effectively. The authors concluded that cup malposition is the most significant potential pitfall of a mini-incision technique, and recommended extending
