The HIFSAT study will compare the standard direct lateral approach to hemiarthroplasty to a new muscle sparing approach (SPAIRE) in femoral neck fracture patients.
Femoral neck fractures are mostly treated with a hemiarthroplasty, where the fractured femoral head is replaced with a metal implant. The most common surgical approach to hemiarthroplasty has been the lateral approach, in which the gluteus medius tendon is partially released from the greater trochanter. Hip pain and limping is not uncommon after this approach has been used. A new surgical approach (SPAIRE) has been developed to alleviate this problem, and in this method the surgeon approaches the injured hip joint from posterior, preserving most of the muscles and tendons around the hip. This trial is designed to assess if this new SPAIRE approach leads to better results than the lateral approach in patients with femoral neck fractures.

The hip joint is approached from laterally, and parts of the gluteus medius tendon is released from the greater trochanter before the hip joint is entered from the anterior side.
The hip joint is entered from posterior, and the approach preserves the external rotators of the hip joint.

RECRUITINGHarris Hip Score ( HHS)
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).
Time frame: 4 months

It covers four domains: Pain, function, presence of deformity and range of motion. The score ranges from 0 (worst) to 100 (best).
Time frame: 12 and 24 months
Oxford Hip score
Oxford Hip Score(OHS) is a patient reported outcome measure( PROM), OHS is designed to assess outcome after total hip replacement. It has 6 questions on pain and 6 questions on mobility. 5 categories of answer from worst to best. The range is 0-48.
Time frame: 4,12 and 24 months
EuroQol-5d-5l
EuroQol-5d-5l is a descriptive system comprises 5 dimensions: Mobility, self-care, usual activities, pain/discomfort and anxiety/depression. Each dimension has 5 levels: no problems, slight problems, moderate problems, severe problems and extreme problems. This decision results in a 1-digit number that expresses the level selected for that dimension. The digits for the 5 dimensions can be combined into a 5-digit number that describes the patient's health state, and these digits can be converted into a single numerical value reflecting how the health state is according to the preferences of the general population of a country/region.
Time frame: 4,12 and 24 months
Trendelenburg test
This platform is for informational purposes only and does not constitute medical advice. Always consult a qualified healthcare professional.
This is a test to identify weakness in gluteal muscles, that can be seen in patients after hip surgery. Unilateral weakness in the gluteal muscles can for instance because nerve damage, trauma to the muscle or rupture of the tendon. The test will be performed as described by Hardcastle and Wade. The patient will be asked to raise their foot from the ground with 30º of hip flexion. The patient will be instructed to raise the non-stance side of the pelvis as high as possible with the examiner supporting the patient by holding their hands if needed. If the patient is not able to maintain this position for 30 seconds, or not being able to raise the hip of the non-stance side to above the level of the stance-side, the Trendelenburg test is considered positive.
Time frame: 4,12 and 24 months
New Mobility Score (NMS)
NMS consists of 3 questions about ambulation indoor, outdoor and the ability to go shopping. Each question has 4 alternative answers yielding 0-3 points, and the maximum score is 9.
Time frame: 4,12 and 24 months
Short Physical Performance Battery (SPPB)
The Short Physical Performance Battery is an assessment tool made specific for screening of physical function among older adults. SPPB has 3 different tests: Balance, walking speed and rising from a chair. Scorings range from 0-12, best possible is 12.
Time frame: 4, 12, an 24 months
Numerical Pain Rate Scale( NPRS)
Unidimensional measure of pain intensity in adults, describing pain extreme from 0 no pain at all to 10 the worst pain imaginable.
Time frame: 4, 12 and 24 months
Duration of surgery
Duration of the operation in minutes
Time frame: 1.st day after surgery
Preferred Walking Speed
A four-meter distance is marked on the floor, and the patients are instructed to walk this distance in their normal speed, as if they were walking down a street. The distance is walked twice, and the fastest speed is recorded. The subject can use any walking aids, and this is recorded.
Time frame: 4,12 and 24 months
Repeated Chair Stand Test
In the repeated chair stand test the participants are asked to fold their arms across their chest (the armrests shall not be not used) and stand up from the chair 5 times. This is timed by the examiner, and points are given from 0 to 4
Time frame: 4,12 and 24 months
Cumulated Ambulation Score
This will be recorded at day 1-3 for all patients. This score assesses the patients' early mobility by evaluating their ability to rise from bed, rise from a chair and walk indoor (walking aids permitted).
Time frame: 1-5 days after surgery
Timed up and go test
This test measures the time that the person uses to rise from a chair, walk three meters, turn around and walk back to the chair, and sit down again, turning 180 degrees. The person can use any mobility aids that he/she would normally use. The TUG test is being scored by the total time measured
Time frame: 4,12 and 24 months
Use of analgesia during admission
Analgesia during the first calendar day after surgery will be recorded as morphine equivalents according to a calculation table published by the Norwegian Directorate of Health.
Time frame: 1. day after surgery
Adverse events
Any adverse events will be recorded during the whole study period
Time frame: 0-24 months
Days Alive At Home (DAH)
Days alive and at home will be measured at 4,12 and 24 months. Patients wish to stay most of their lives at home, this measurement will tell us how long they could stay home and if they came home after their hip fracture.
Time frame: 4,12 and 24 months
