Recent literature on the subject is reviewed, and the role of Syme's amputation, reconstructive surgery and prosthetic management is discussed in relation to the severity of the condition. Amputation, which should be performed between 18 months and two years old is specifically recommended for total fibula absence with ankle instability. The operative technique is detailed.
A study has been made of lower limb amputation statistics from morbidity data from the State Health Departments in New South Wales, Queensland, and Western Australia. The incidence of lower limb amputation in these three States was 22.6 in 1981, 22.5 in 1983, and 23.6 in 1984. Incidence was lowest in New South Wales and highest in Western Australia. Below-knee amputation was more common than above-knee except in Western Australia in the years 1981 and 1983. Males had slightly more amputations than females. Incidence increased steadily with age, rising rapidly after 55 years. Vascular disease was the most common cause of major amputation. Of malignancies, skin cancers, both malignant melanoma and other forms, were causes of major and minor amputations in addition to bone malignancies. These three Australian States have a lower incidence of amputation than the United Kingdom or Finland.
Upper extremity amputations in Denmark between 1978 and 1983 comprised 3 percent of all major amputations. Trauma was the main reason for upper extremity amputations.
A case in which inadequate treatment of a nail plate injury resulted in chronic osteomyelitis has been described. Because of its distinct anatomy, trauma to the nail and its associated structures should not be summarily dismissed as an innocuous injury but should be thoroughly examined for phalangeal fracture and laceration of the nail bed.

Unfortunately, amputation surgery is still a very important part of the treatment for diabetic foot problems. The decision-making process must be done thoughtfully, remembering that blood flow is not the only issue. Many factors enter into the decision to perform a partial foot amputation or to perform a more proximal level amputation. Adherence to good surgical principle, proven techniques, and gentle soft-tissue handling can make the difference between a successful and durable amputation or continued complications and frustrations.

A case of team-treated thrombosed popliteal artery caused by blunt limb trauma with open tibia fracture is presented. Thrombosed artery was treated by endovascular pulse-spray method using Angiomed catheter. Implementation of this method allowed us to dissolve thrombus and to retrieve arterial circulation in the limb. In our opinion this procedure was an alternative for traditional surgery. After revascularisation of the limb orthopedic operation on fractured bones was performed using Zespol technique.

Through-the-knee amputation (TKA) is an excellent lower extremity treatment for the ischemic extremity when revascularization is not feasible and a prosthesis is not practical. Over the past 8 years 185 major amputations have been performed at our hospital of which 63 were of the TKA type. In 61 of these an improved technique was used that resulted in nonischemic, strong, and aesthetic stumps with 100 per cent primary healing. Our technique consists of removing the distal 2 cm of the femoral head with the two condyles and allowing the patella to ankylose to the new distal femoral end. In comparison with the other major amputations the TKA with this technique had significant advantages over the above-knee amputation and often was found to be superior to the below-knee amputation especially when rehabilitative ambulation with a prosthesis was not possible.
