The Hip Joint

For centuries, orthopedic surgeons have been managing the pain, limp, and gait disturbance that develop in association with various traumas and diseases of the hip joint. The hip is a ball-and-socket joint that has a good range of movement, but it’s stable and rarely dislocates, even after high-impact trauma, and can withstand repeated motion and a fair amount of wear and tear. However, despite its durability, the hip joint isn't indestructible. With age and use, the cartilage can wear down or become damaged. Muscles and tendons in the hip can get overused, for example, in athletes, leading to hip pain due to muscle strain or tendonitis. Other factors that can cause pain include the abnormal anatomy a person is born with and conditions that develop during the growth and development of bones. Trauma as well as wear and tear due to aging can all lead to progressive arthritic changes. The diagnosis and management of hip injuries has evolved substantially with advances in hip arthroscopy and diagnostic tools such as MRI and new, minimally invasive techniques.

This book provides a detailed account of the hip joint's anatomy and biomechanics and serves as a practical guide for the diagnosis and treatment of hip diseases and injuries at all ages: children, adolescents and adults, and the older population. The book covers recent trends in orthopedic surgery of the hip joint, including the latest advances in revision total hip arthroplasty (THA), computer-assisted navigation for THA, resurfacing of the hip joint, neoplastic conditions around the hip, and indications, complications, and outcomes of hip arthroscopy. The chapters are written by experts who have contributed greatly to the understanding of problems of the hip joint. The book will be appreciated by undergraduate and postgraduate students, experienced hip surgeons, medical doctors, and practicing consultants in orthopedics.

Dr. K. Mohan Iyer obtained his MCPS degree (1971) from the College of Physicians and Surgeons, Mumbai, India; MBBS (1971) from the University of Mumbai; D’Orth. and FCPS Orth. (1975) from the College of Physicians and Surgeons; MS Orth. (1978) from the University of Mumbai; and M. Ch. Orth. (1981) from the University of Liverpool, UK. He wrote three theses on fractures of the patella, excision arthroplasty of the elbow, and excision of the trapezium for carpometacarpal arthritis of the thumb.

From 1971 to 1972, Dr. K. Mohan?Iyer was with K.E.M. Hospital, Mumbai, India, on a resident rotating internship. His other nonorthopedic appointments were as resident house surgeon in general surgery (1973–1974) in K.E.M. Hospital and as SHO (1976) in East Birmingham Hospital, UK. His orthopedic appointments were as resident house surgeon in orthopedics (1973) and resident registrar orthopedics (teaching post; 1974–1976) in K.E.M. Hospital and as registrar in orthopedics (1976–1977), Dryburn Hospital, Durham, UK, in addition to numerous other locum consultant and specialist registrar jobs.

Dr. K. Mohan Iyer has presented numerous papers at state, national, and international conferences at Singapore and Bangkok. He was invited to be on the faculty of the CME programs of numerous instructional courses and regional orthopedic association conferences in India. He was in charge of the teaching program in orthopedics for undergraduate students and an examiner for the MBBS degree at the University of Bangalore, India. He has also carried out a wide range of operative work on all kinds of major fractures, as well as arthroscopy of the knee, spinal surgery, and elbow and total hip replacements, and has published numerous articles and book chapters.

He has also done original research work as seen on his website at kmohaniyer.com. He has been instrumental in devising "A Modified Posterior Approach to the Hip Joint" which he has been following from 1981 till today.

In 2008, Dr. K. Mohan Iyer moved back to his home town, Bengaluru, India.
