Dr. Cotler was president of the American Board of Orthopedic Surgery in 1982-83 and earned the Lifetime Achievement Award from the American Spinal Injury Association in 2003.
A grandson of Russian immigrant farmers in Cumberland County, N.J., "he worked extremely hard his whole life," daughter Michele Bronkesh said.
"It was all about hard work, academics, and ethics," she said. "He had this really strong moral fiber."
Born in Bridgeton, Dr. Cotler earned a bachelor's in science at Ursinus College in 1948 and graduated from Jefferson Medical College in 1952.
After completing his residencies in 1957, he began as an instructor at Jefferson Medical College and an associate orthopedic surgeon at Jefferson University Hospital.
He became the Dr. Everett J. and Marian Gordon Professor at the medical college in 1991.
He was affiliated with several hospitals in South Jersey and Southeastern Pennsylvania, serving at Elizabethtown Hospital for Crippled Children and Youth as president of its medical staff from 1971 to 1975.
His daughter said that he published "hundreds of clinical research papers and coauthored several orthopedic textbooks" and lectured at scientific conferences worldwide.
He was chairman of the North American Spine Society in 1996-97 and chairman of the board of councilors at the American Academy of Orthopedic Surgeons in 1975-76.
The Jewish National Fund named him its Man of the Year in 1997; the Arthritis Foundation of Eastern Pennsylvania gave him its Sir John Chamley Award in 2007; and Ursinus College gave him an alumni award in 2003.
Besides his daughter, Dr. Cotler is survived by his wife of 62 years, Florence; son Dr. Howard Cotler; four grandchildren; and a great-grandson.
A graveside service was set for 11 a.m. Sunday, April 13, at Locustwood Cemetery, 500 Route 70 West in Cherry Hill.
