Genu varum

Genu varum (Blount's Disease) is a deformity marked by medial angulation of the leg in relation to the thigh, an outward bowing of the legs. It is also known as bandy-leg, bowleg, bow-leg, and tibia vara. Usually there is an outward curvature of both femur and tibia, with at times an interior bend of the latter bone. more...

At birth all children are more or less bandy-legged. The child lies on its nurse's knee with the soles of the feet facing one another; the tibia and femora are curved outwards; and, if the limbs are extended, although the ankles are in contact, there is a distinct space between the knee-joints. During the first year of life a gradual change takes place. The knee-joints approach one another; the femora slope downwards and inwards towards the knee joints; the tibia become straight; and the sole of the foot faces almost directly downwards.

While these changes are occurring, the bones, which at first consist principally of cartilage, are gradually becoming ossified, and in a normal child by the time it begins to walk the lower limbs are prepared, both by their general direction and by the rigidity of the bones which form them, to support the weight of the body. If, however, the child attempts either as the result of imitation or from encouragement to walk before the normal bandy condition had passed off, the result will necessarily be either an arrest in the development of the limbs or an increase of the bandy condition.

If the child is weakly, either with rickets or suffering from any ailment that prevents the due ossification of the bones, or is improperly fed, the bandy condition may remain persistent. Thus the chief cause of this deformity is rickets. The remaining causes are occupation, especially that of a jockey, and traumatism, the condition being very likely to supervene after accidents involving the condyles of the femur. In the rickety form the most important thing is to treat the constitutional disease, at the same time instructing the mother never to place the child on its feet. In many cases this is quite sufficient in itself to effect a cure, but matters can be hastened somewhat by applying splints. When in older patients the deformity arises either from traumatism or occupation, the only treatment is surgery.

Orthopaedic training in developing countries
From Journal of Bone and Joint Surgery, 1/1/05 by Lavy, C B D

More than 80% of the population of the world and a vast reservoir of orthopaedic pathology is located in developing countries. Our experience is mainly in central and sub-Saharan Africa, yet our conclusions hold for poor countries of all continents.


The need for both elective and emergency orthopaedic services in developing countries is great. Most of the degenerative musculoskeletal diseases seen in the West are prevalent, as well as conditions such as untreated club foot, gross genu varum and valgus, tuberculosis of the spine and severe chronic osteomyelitis. Road traffic accidents are becoming an epidemic. More than 80% of deaths in road traffic accidents and more than 90% of those involving children occur in developing countries.1 In Malawi there are only four orthopaedic surgeons to care for a population of 12 million people. The need for postgraduate training in orthopaedic surgery in a developing country is undeniable, but whether this should be the only level of training depends on the general level of health services in the country. In Malawi, most of the 25 district hospitals have only one doctor of Senior House Officer level and no specialists. The majority of patients are managed by paramedical personnel known as clinical officers. Our main emphasis in training is to instruct these clinical officers in practical orthopaedics and the treatment of fractures. Each district hospital has one or more orthopaedic clinical officers (OCOs), who are able to treat most trauma safely and relatively conservatively. We have a visiting consultant support service which is patchy at present, but will improve as the number of trained specialists increases. Thus, in Malawi a two-tiered orthopaedic training programme has evolved, where we can train OCOs and postgraduate orthopaedic surgeons side-by-side. The majority of the OCOs work at the district level, while the orthopaedic surgeons are in central or teaching hospitals providing service for clinical referral and increasing the scope of training programmes. We believe this is to be a realistic, cost-effective, and achievable strategy. Other developing countries, where there are more doctors, may aim to have a postgraduate level surgeon at every district hospital (either an orthopaedic surgeon, or a generalist with orthopaedic experience).


A developing country has three options available to train its orthopaedic surgeons. It can try to carry out all the training within its own borders. For the bigger countries with established medical structures, such as Nigeria and Uganda, this is feasible. They have well-run postgraduate programmes in orthopaedic surgery. In smaller countries with less developed services where there are very few qualified trainers, the breadth of training is severely limited, even though the spectrum of disease may be wide.

The second option aims to address the problem with a regional rather than a national approach. In our region we have recently set up a training scheme under the newly formed College of Surgeons of East Central and Southern Africa (COSECSA).2 This allows trainees to augment the teaching available in their own country and to work under approved trainers in other countries in the region. COSECSA organises a membership examination in basic surgical sciences and an exit level fellowship in orthopaedics. However, the existence of a training scheme and an examination system does not mean that residents automatically receive good training. Two other components are needed, namely good hospital conditions and keen trainers. These are not always available together in government or university hospitals, and in Malawi we have encouraged cooperation with private and mission hospitals in order to benefit from their facilities and expertise. With such cooperation the trainee gets the best that the country can offer. In other countries the private sector is not always amenable to participate in training, and where private patients are limited there may even be opposition or obstruction to training programmes.

The third option is to send trainees to more developed countries for all of their instruction. Historically, this was the only option for many. It will always remain a possibility, and although the training is usually of a high standard there are several disadvantages. The pathology in more developed countries is very different and few trainees who do all their postgraduate training in developed countries ever return. We believe that there are benefits to a short period in a developed country, probably at the end of the national or regional training. This should be for approximately one year and concentrate on a particular aspect such as joint replacement or spinal surgery. Where possible such visits should be arranged as a formal exchange between trainees from developed and developing countries. The benefits of a visit at this stage in training are many and include exposure to modern technology, a different medical culture and the forging of academic and professional links and friendships, many of which will last a lifetime. These links facilitate orthopaedic education in its broadest sense, allowing the exchange of ideas to continue long after the formal period of training is over.

After training

Trained orthopaedic surgeons are desperately needed in developing countries but their provision in a poor country often highlights other needs. Modern orthopaedics is expensive, and a surgeon trained to the highest theoretical and practical level in internal fixation of fractures can become frustrated working in a country where a simple small fragment plate and six screws costs more than the annual health budget for ten people. The surgeon will have to struggle with out-of-date or broken equipment, theatres of less than perfect cleanliness and staffing levels which are so low that nurses may not even meet all the patients, let alone nurse them. This encourages the use of less costly conservative methods of treatment. Often these are appropriate, but sometimes they are second best, and it is a struggle not to compromise the quality of care. Salaries paid by governments to specialists in developing countries are often insufficient to keep a family fed, let alone cover school fees or buy a car. Many orthopaedic surgeons have to undertake private practice just to survive. Continuing medical education is seldom mandatory in developing countries and even if the surgeon is keen to keep up-to-date, this is not easy, as colleagues may not be like-minded; journals are few and the internet, if available, is usually very slow. We are fortunate in our region of Africa as COSECSA tries to address the need of continuing medical education, but conferences usually involve travel to one of the other countries in the region which is time-consuming and costly. If trained orthopaedic surgeons are to stay and work in their countries, efforts to improve the conditions of work, remuneration, and incentives to stay must be a priority for national governments.

The challenge to developed countries

The orthopaedic needs of people in developing countries are immense and the plight of our orthopaedic colleagues both trained and in training is precarious. It is useful to compare our lot with that of our colleagues in developing countries. How may concerned orthopaedic surgeons best help? Some will want to visit, and we have benefited greatly from open-minded orthopaedic visitors, bringing both expertise and equipment. A recent hip course sponsored by the Royal College of Surgeons and industry has enabled us to begin a joint replacement service. Programmes of volunteer visiting surgeons can greatly strengthen local postgraduate training programmes. secondment of trainees from programmes in the United Kingdom allow them to visit developing countries, bringing many mutual benefits. Such a visit allows trainees to expand their minds and catch a glimpse of the orthopaedic problems of the underdeveloped world. They see the natural history and results of untreated pathology. Surgeons who manage club feet may never have seen teenagers or adults with severe untreated feet walking on the head of the talus and the lateral malleoli. Few have seen a sequestrum involving most of the tibia or patients who have walked for months on untreated displaced fractures of the ankle. Visits from trainees also forge friendships and mutual respect for colleagues in different parts of the world. Most who have visited our unit have also been involved in mutually beneficial research projects. Heads of training programmes in the United Kingdom may find appropriate spaces for trainees from developing countries who wish to acquire particular skills.

Material support in the form of donated orthopaedic equipment can go a long way toward improving the training environment of residents in the developing world. As well as equipment, the donation of 'knowledge', by, for instance, subscriptions to international journals can be invaluable. The internet has opened up access to electronic information for trainees in developing countries, but there is still the need for equipment and continued financial support to make it available.

The orthopaedic world is becoming smaller and closer. When the senior author (CBDL) made arrangements to visit Malawi in 1994, it was by aerogramme as the internet had not yet been established in Malawi, and phone lines were unreliable. Now that communication is almost instantaneous, it is our hope that orthopaedic training in the developing countries will be a concern for us all, that training programmes in the developed world will ask what they can do on a global level, and that communications, visits in both directions, bilateral research programmes and mutual understanding will continue to bring us closer together.
