Dr. William H. Dillin


“As mathematical and absolute certainty is seldom to be attained in human affairs, reason and public utility require that judges and all mankind, in forming their opinions of the truth of facts, should be regulated by the superior number of the probabilities on the one side, or the other, whether the amount of these probabilities be expressed in words and arguments or by figures and numbers.”

-William Murray, 1st Earl of Mansfield (1705-1793)

William Dillin, MD completed the neurosurgery and orthopedic spine fellowship at Pennsylvania Hospital in Philadelphia in 1985. He was a partner at the Kerlan-Jobe Orthopedic Clinic in Los Angeles for 35 years and concurrently an associate at the Cedars-Sinai Kerlan- Jobe Institute for 7 years.

During Dr. Dillin’s tenure, the Kerlan-Jobe Orthopaedic Associates were either the team physicians or consultants to the Los Angeles Dodgers, the Los Angeles Angels of Anaheim, the Los Angeles Rams, USC football, the Anaheim Mighty Ducks, the Los Angeles Kings, the Los Angeles Sparks, the Los Angeles Lakers, the Los Angeles Clippers, USA Olympics, the PGA Tour and Loyola Marymount University in Los Angeles.

Evidence-based medicine has been the cornerstone of Dr. Dillin’s education during his spine surgery fellowship in Neurosurgery and Orthopaedic Surgery and the format for his subsequent clinical spine practice.

An evidence-based practice features the best available information translated into patient care. Critical thinking in medicine, and the combined infusion of traditionally designed spine studies and the data mining models of machine learning, create the current state of spine knowledge.

Evidence-based practice is devoted to the flexible adaptation of clinical spine medicine as the science evolves. As the aviation world has modeled through recurrent pilot training, practicing what one knows and acquiring new skills are cornerstones to offering patients the best options.

For over 35 years, Dr. Dillin has traveled to refine and acquire these skills. His particular interest is spine surgery simulation, not only as demonstrated in cadaver procedure practice, but represented in the new VR-Haptic-Gaming Computer configurations.

Since July 1985, Dr. Dillin has been exclusively devoted to clinical spine, interventional spine, and spine surgery practice. He has performed between 9,000 to 10,000 spine operations/interventions covering a wide range of technical spine procedures.

Dr. Dillin embraces his mentors, Dr. Fred Simeone in spine neurosurgery, and Dr. Richard Rothman in orthopedic spine surgery. Years may have passed, but the influence of great teachers never disappears. Dr. Dillin is in practice and accepts forensic consults.
