Aim. To review the evolution of the orthopaedic surgical care offered at a small rural hospital in western Nepal. The United Missions Hospital of Tansen (UMHT) was established in 1954 and has progressed substantially over the past 55 years. Located in the hills 300 km west of Kathmandu, it services not only Palpa District but also the surrounding nine districts and Indian patients from across the nearby border. The hospital has progressed from a simple medical clinic to a 165-bed hospital with four operating theatres, a new emergency department and multiple outpatient clinics. Orthopaedics in particular has come a long way from solely non-operative care such as plasters, splints and traction, to plating and intra-medullary nailing with intra-operative imaging facilities. This talk will review the progression of services in the region and highlight how western intervention has drastically improved the health care and lives of people in and around Tansen. Methods. UMHT is a 165-bed hospital with medical staff covering paediatrics, general medicine, general surgery and orthopaedics. Exact specialty coverage can vary depending on expatriate cover and locally trained staff expertise. There are around 315 Nepali employees, and eight mission appointees, mainly from the UK, USA, Australia and Sweden. There are six resident medical officers who are post internship and usually completing GP training schemes. The hospital is accredited to train 10 interns per year and frequently takes local and international medical students on rotation. Surgical facilities include daily outpatient surgical clinics of 30–60 patients, two minor operation theatres and two operating theatres. Generally, these are run as one orthopaedic and one general surgical theatre. This review is based on the experiences of Dr John Bosanquet, Dr Sandy Bosanquet and Dr Lachlan Host in their outreach trips to this hospital and in particular will focus on the progression over the last 10 years of the orthopaedic services available. Major advances have been in the provision of x-ray and CT facilities, improved supply of sterile equipment, introduction of IM nailing using the SIGN nail, and the training of local staff to continue the work. Conclusions. UMHT is a work in progress and is only made possible by the contributions of the many doctors, nurses, teachers and other professionals who willingly offer their services to help those less fortunate. Even more importantly is the funding provided from multiple organisations to sustain this outreach. The challenge remains, as in any outreach offered, of providing a service that is sustainable long-term. To date, UMHT has stood the test of time and there is much to be learnt from its example in the establishment of similar outreach projects. Future challenges for Tansen include the need for improved sterile facilities, the challenges of introducing elective surgery, particularly arthroplasty, provision of spine and neurosurgical facilities, and retention of skilled personal in what can be an isolating environment
