Bone scan utilization in the differential diagnosis of exercise-induced lower extremity pain.

In 4 patients with lower extremity pain and either negative or equivocal radiograhic findings, the bone scan was definitely positive for stress fracture in all, accurately localized the lesion, and permitted proper therapy. The condition in all instances proved to be a microfracture at the origin or insertion of a muscle. The pain was always intensified by physical activity.

Mechanism of extremity injuries occurring during ejection from F-4 aircraft.

A retrospective study of F-4 ejections from 1967-77 revealed extremity injuries during the ejection sequence in 43 of 399 ejections for an injury rate of 10.8%. Of the 43 ejections, there were 111 extremity injuries. The injuries were divided into two groups: severe and minimal. Severe injuries consisted of fractures, dislocations, ligamentous tears, and nerve palsys. There were 76 severe injuries. Minimal injuries consisted of contusions, lacerations, and minor sprains. There were 35 minimal injuries. The 76 severe injuries were divided into 50 upper-extremity and 26 lower-extremity injuries. The majority of the severe upper-extremity injuries involved the proximal joints and the majority of the severe lower-extremity injuries involved the distal joints. When the windblast/windflail injuries were compared to the various variables, correlation was seen with the knots indicated airspeed (KIAS), aircraft attitude, and aircraft type. The incidence of extremity injury increases with increased airspeed and a nose-down attitude, and decreases in the RF-4C aircraft configuration.

The role of culture in primary health care. Two case studies.

The purpose of this article is to show the importance of traditional healers in primary health care (PHC) services. Most countries, despite adopting PHC, have not incorporated traditional healers into this service. The article also illustrates how traditional healers fulfil three of Morrell's four PHC objectives, and how incorporating traditional healers into health services will fulfil the fourth objective. The first contact between a black African patient and health care services usually takes place in the traditional healing system. Therefore health workers should realise that the traditional care system is important if PHC is to succeed. Traditional healers are the most important primary health care service in an African setting. This is highlighted by 2 cases described in the article.

[Replantation in multiple injuries?].

While amputations of extremity parts are not uncommon in multiple trauma, replantation of these parts is not always feasible. Initial therapy will concentrate on plain survival. We suggest an aid to identify those patients with multiple trauma and extremity amputation, who should undergo replantation.
