Dr. Ain is not accepting new appointments at this time. Dr. Michael Ain is an associate professor of orthopaedic surgery and neurological surgery at the Johns Hopkins School of Medicine. His areas of clinical expertise include achondroplasia, clubfeet, orthopaedic surgery, pediatric orthopaedics and skeletal dysplasias.
Dr. Ain and his colleagues have developed groundbreaking surgical techniques for patients with spinal deformities and skeletal dysplasia, including the design of prostheses and instruments for people less than four feet tall and the use of pedicle screws instead of hooks and wires for scoliosis surgery.
Dr. Ain received his undergraduate degree in mathematics from Brown University. He earned his M.D. from Albany Medical College of Union University. He completed his residency at Albany Medical College and performed a fellowship in pediatric orthopaedic surgery at the Johns Hopkins Hospital.
Dr. Ain's research interests include skeletal dysplasias, scoliosis, achondroplasia, pediatric trauma, pediatric spinal deformities, hip dysplasia and pediatric spinal deformities.

Research & Publications
Dr. Ain’s research focuses on the outcomes of surgical treatment on patients with skeletal dysplasias and on pediatric orthopaedics.
Dr. Ain, along with residents and medical students, has published several papers on outcomes of patients with skeletal dysplasias. They have looked at the malalignment of lower extremities in achondroplasia, results of cervical fusion in patients with skeletal dysplasias and results of thoracolumbar fusions in patients with achondroplasia.
His future research plans include looking at the natural history of low-back pain in achondroplasia, the outcomes of decompression in achondroplasia and the natural history of kyphosis in achondroplasia.
