Anterolateral Versus Direct Lateral Approach in Hemiarthroplasty for Hip Fracture

September 29, 2022 updated by: Sykehuset Innlandet HF

Anterolateral Versus Direct Lateral Approach in Hemiarthroplasty for Hip Fracture: A Randomised Study

Patients with dislocated hip fractures are randomised to cemented hemiarthroplasty with an anterolateral approach or a direct lateral approach.

Study Overview

Detailed Description

Dislocated intracapsular hip fractures are usually treated with cemented hemiarthroplasty. In Norway, a direct lateral approach is most often used, as recommended in national guidelines. In total hip arthroplasty, however, minimally invasive approaches are also commonly used, and may improve the clinical results, as compared to posterior or direct lateral approaches.

The aims of the present study are to evaluate the effect of the minimally invasive anterolateral approach (Watson-Jones approach) compared to the direct lateral approach (Hardinge approach) to the hip joint in hemiarthroplasty after dislocated hip fractures.

Patients with dislocated hip fractures who are fit for cemented hemiarthroplasty are randomised to surgery with an anterolateral approach or a direct lateral approach.

  • able to walk, with or without walking aids, prior to the injury.

Exclusion Criteria:

  • young and healthy patients with displaced hip fractures who are recommended total hip arthroplasty or open reduction / internal fixation of the fracture.
  • patients with severe comorbidity and high risk of cement-related complications who are recommended uncemented hemiarthroplasty (some, but not all, patients with ASA (American Society of Anesthesiologists) grade 4).
  • not able to give informed consent.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Anterolateral approach

The minimally invasive anterolateral approach (Watson-Jones approach) is performed with the patient in supine position. An oblique incision is made from just dorsal to the anterior superior iliac spine, and extended distally to the greater trochanter. After the fascia is incised, deep dissection continues in the plane between the tensor fasciae latae and the gluteus medius muscles. The joint capsule is exposed and opened. The femoral head and neck are resected and the femoral canal is reamed according to the preoperative plan.

A femoral stem (Link Lubinus SPII) is fixed using bone cement (Heraeus Medical Palacos R+G pro) and connected to a bipolar femoral head (Zimmer Multipolar).

After implantation of the prosthesis, the fascia, subcutis and skin is closed in separate layers with sutures.

Active Comparator: Direct lateral approach

The direct lateral approach (Hardinge approach) is performed with the patient in a lateral decubitus position. A straight or curved longitudinal incision is made over the greater trochanter, and the fascia is incised longitudinally. The anterior aspect of the gluteus medius and minimus muscles are separated from the greater trochanter. The joint capsule is exposed and opened. The femoral head and neck are resected and the femoral canal is reamed according to the preoperative plan.

A femoral stem (Link Lubinus SPII) is fixed using bone cement (Heraeus Medical Palacos R+G pro) and connected to a bipolar femoral head (Zimmer Multipolar).

After implantation of the prosthesis, the gluteus medius and minimus muscles are reinserted using osteosutures. The fascia, subcutis and skin is closed in separate layers with sutures.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Harris Hip Score (HHS)
Time Frame: 12 months
Harris Hip Score (HHS) is an outcome measure for hip-related symptoms. The score is based on both patient-reported information and clinical examination, and is administered by a qualified health care professional. It covers four domains: Pain, function, absence of deformity and range of motion. The score ranges from 0 (worst) to 100 (best).
12 months

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
EuroQol questionnaire (EQ-5D)
Time Frame: 12 months
Quality of life is measured by the EuroQol questionnaire (EQ-5D). EQ-5D is a validated generic health-related quality-of-life instrument. It consists of two parts: EQ-5D descriptive part and EQ-5D visual analogue scale. The descriptive part includes five dimensions (mobility, self-care, usual activities, pain/discomfort, and anxiety/depression), each with three possible answers ("no problems", "some problems", and "major problems"). EQ-5D VAS is a visual analogue scale of self-related overall health, ranging from 0 (worst imaginable health state) to 100 (best imaginable health state).
12 months
Patient-reported limping
Time Frame: 12 months
Patient-reported limping is a sub-score of the Harris Hip Score. The patients describe their limping as (1) "none", (2) "slight", (3) "moderate" or (4) "severe or unable to walk".
12 months
Patient-reported use of walking aid
Time Frame: 12 months
Patient-reported use of walking aid is a sub-score of the Harris Hip Score. The patients describe their use of walking aid as (1) "none", (2) "cane/walking stick for long walks", (3) "cane/walking stick most of the time", (4) "one crutch", (5) "two canes/walking sticks" or (6) "two crutches or unable to walk".
12 months
Trendelenburg test
Time Frame: 12 months
Trendelenburg test is a clinical test for the integrity of hip abductor muscle function. The test is positive when the patient is unable to maintain the pelvis horizontal to the floor when standing on one leg.
12 months
Timed Up and Go (TUG)
Time Frame: 12 months

The Timed Up and Go (TUG) test is a performance-based measure of functional mobility that was initially developed to identify mobility and balance impairments in older adults.

The patients start in a seated position, walk 3 meters, turn around, walk back to the chair and sit down. The time starts when the patient is commanded to start and stops when the patient is seated.
