"CONCLUSION: Selective fatty atrophy of the ADQ is not a rare finding on MR examination
of the foot and ankle, being seen in 6.3% of all studies and in 7.5% of all studies in females.The clinical relevance of selective ADQ atrophy seen on MRI is uncertain."

Conclusion: Prevalence of fatty muscle atrophy of the ADM muscle—classically considered to represent entrapment neuropathy—is between 4% and 11% in both asymptomatic volunteers and patients with foot pain, and it increases with age.
