The Hip and Pelvis

Nicholas H. Mast MD, a private practice orthopedic surgeon in San Francisco, CA specializing in surgery of the hip and pelvis.

Dr. Mast is board certified in orthopedic surgery and trained by some of the very best in hip surgery. In addition to completing a residency in orthopedic surgery, Dr. Mast has completed advanced postdoctoral fellowships in pelvic and acetabular trauma and reconstruction.

He has done advanced training in the anterior approach for hip replacement. He has completed international fellowship training in hip preservation including periacetabular osteotomy and hip arthroscopy.

I am a specialist in surgery of the Hip and Pelvis in San Francisco. My interests include non-replacement options for hip arthritis, as well as the latest techniques in minimally invasive hip replacement and resurfacing, I am also trained in the management of complex pelvic and acetabular trauma.

My credentials include completion of residency under the direction of Professors Harold Dunn and Charlie Saltzman at the University of Utah. In addition to an excellent exposure to the breadth of orthopedics, I had an excellent exposure to joint replacement and osteotomy under the tutelage of Dr. Chris Peters, Dr. Peter Stevens, Dr. Harold Dunn, and Dr. Aaron Hofmann. I was quite involved in the clinical experience of the PAO and Surgical dislocation while working with Dr. Peters.

Following completion of residency, I spent 1 year under the direction of Dr. Joel Matta where I became a student of hip and pelvis surgery. While under Dr. Matta’s direction I participated in over 180 anterior approach total hip arthroplasties, over 40 acetabular/pelvic fractures, and over 25 PAOs. I became well versed in the use of the orthopedic table for hip and pelvis surgery. I became quite comfortable in the application of the Heuter approach for a wide variety of hip pathologies. In our trauma work, I became familiar with the philosophy and surgical stratagem of Letournel. Following my work under Dr. Matta, I returned home to work with my father, Dr. Jeffrey Mast. I had six very valuable months working along side my father in a private general orthopedic practice setting in Reno, Nevada. During this time, I continued to perform complex procedures of the pelvis and acetabulum, as well as anterior approach arthroplasty.
