History of the clinic

The Gilmore Groin and Hernia Clinic was established in 1991 by Mr Jerry Gilmore.

During research for his master of Surgery Degree he developed an interest in wound healing which evolved into specific interest in soft tissue injuries and repair. In 1980 he recognised the syndrome of Groin disruption in sportsmen and undertook the first successful repair.

The technique later became known as “Gilmore’s Groin” or Sportsmans Groin (and also the misnomer sports hernia.) This pioneering work which has resulted in the successful and rapid restoration of many sporting careers, was recognised nationally by the award of Fellowship of the Institute of Sports Medicine in 1995.

In 1999 Mr Simon Marsh, a prize winning Cambridge Graduate and Consultant in Colchester, joined the clinic because of his surgical expertise and knowledge of different sports and their associated injuries. He was appointed Surgical Director of the Clinic following Jerry Gilmore’s retirement from practice in October 2010.

Mr Simon Marsh, Consultant Surgeon

Simon Marsh trained at Trinity College Cambridge and the Clinical School, Addenbrookes Hospital.  He qualified in 1987, having been awarded a BA in 1985. In 1992 he was made a Fellow of the Royal College of Surgeons in England and granted an MA from Cambridge.

In 1996 he was awarded an MD by the University of Cambridge and received the Intercollegiate Fellowship in General Surgery. In 1999 having been appointed as Consultant surgeon in Colchester he joined the team at 108 Harley Street. In 2006 he halved his workload within the NHS to dedicate more time to working in Harley Street.

Following qualification he developed an interest in sports medicine and has advised on many sports, including equestrian events, motorcycle speedway and rugby.  This expertise has ensured his success since joining The Gilmore Groin and Hernia Clinic where he has become adept and experienced in assessing, diagnosing and treating patients not only with hernia of all types but also with Gilmore’s Groin.

Gilmore's Groin (groin disruption) and how it is treated

The syndrome was first recognised in 1980, following the successful treatment of three professional footballers who had been unable to play for many months because of undiagnosed injuries of the groin. Although some people refer to it as a Sportmen’s Hernia there is no true hernia present. Groin disruption (Gilmore’s Groin) is a severe musculo-tendinous injury of the groin, which can be successfully treated by the surgical restoration of normal anatomy.
