Key result

Patients with femoroacetabular impingement had significantly decreased flexion, internal rotation, and abduction in comparison to normal hips (p < 0.001).

Why the study?

Does the HipMotion CT-based method accurately assess hip range of motion and identify differences between normal hips and those with femoroacetabular impingement?

Population

150 patients with normal hip range of motion and 31 consecutive hips with femoroacetabular impingement…

Comparison

CT-based method for noninvasive… vs Normal hips (for the clinical comparison cohort)

Implication

May support HipMotion CT analysis for FAI ROM assessment; leaves open prospective validation before clinical adoption.

Type

Observational (n=181)

Structured PICO

Does the HipMotion CT-based method accurately assess hip range of motion and identify differences between normal hips and those with femoroacetabular impingement?

P
Population
150 normal patients and 31 consecutive hips with femoroacetabular impingement evaluated using a novel CT-based three-dimensional assessment method.
E
Exposure
CT-based method ('HipMotion') for noninvasive three-dimensional assessment of femoroacetabular impingement
C
Comparator
Normal hips (for the clinical comparison cohort)
O
Outcome
Accuracy, reliability, and reproducibility of the HipMotion method, and hip range of motion (flexion, internal rotation, abduction)surrogate

Main Result

p-value: p=<0.001

The HipMotion CT-based method provides an accurate and reliable 3D assessment of hip range of motion, successfully quantifying functional deficits in patients with femoroacetabular impingement.

Cite This Study

Tannast et al. (2006) conducted an observational in Femoroacetabular impingement (FAI) (n=181). Femoroacetabular impingement vs. Normal hips was evaluated on Hip range of motion (flexion, internal rotation, and abduction) (p=<0.001). Patients with femoroacetabular impingement had significantly decreased flexion, internal rotation, and abduction in comparison to normal hips (p < 0.001).
