Sam Elattar, MD
Limb Lengthening Fellow 201

Dr. Elattar graduated from medical school in his home country of Egypt where he ranked 7th in his class of 1500. This helped him to enroll in his desired residency program at the prestigious Cairo University Medical School, which is heralded as the number one orthopaedic residency program in Egypt. Dr. Elattar originally intended to pursue a career in sports medicine. However, he encountered a major turning point when his mentor recommended to him to focus his PhD thesis on the topic of "Arthroscopic Assisted Ankle Arthrodesis." Ever since then he found himself giving his whole attention to foot and ankle surgery with a special interest in trauma and deformity corrective treatments.

The foot and ankle speciality is underexplored and still evolving in Egypt, which has led Dr. Elattar to embark on a crusade in America looking to enhance his knowledge and technique in foot and ankle surgery. He completed a foot and ankle research fellowship with the Univeristy of Alabama just prior to joining the Limb Lengthening team where he achieved two paper presentations accepted at the 2015 American Academy of Orthopaedic Surgeons and three paper presentations at the 2015 Mid America Orthopaedic Association. Dr. Elattar is excited for this opportunity to further develope his goal of becoming a comprehensive lower extremity surgeon.
