Dynamic bone scintigraphy in osteochondritis dissecans.

We report a retrospective study of eighteen patients with pain in the knee or ankle, eleven of whom had osteochondritis dissecans. In these patients the bone-flow time-activity curves were observed after an intravenous injection of a bolus of 99mTc MDP. The curves varied according to the severity of the clinical signs and symptoms. The diagnosis rate was 29% with static scintigraphy and this improved to 57% when dynamic flow studies were used. A positive pattern in the dynamic study together with radiographs and static scintigraphs raised the diagnosis rate to 100%; the sensitivity was 90%. These preliminary results show that dynamic bone scintigraphy holds promise as a technique for identification and management of this condition.

Overview of computed tomography of the temporomandibular joint.

Computed tomography of the temporomandibular joint has been shown to be an accurate method of assessing the position of the disk. To date, we have examined over 500 patients with this modality and have found it also to be effective in the evaluation of other osseous and soft tissue abnormalities. An overview of temporomandibular joint pathology is presented, including the range of osteoarthritic changes from spur formation to complete fusion. Anterior dislocation, with and without reduction, and closed lock are demonstrated. A heretofore unreported phenomenon--posterior dislocation of the meniscus with open lock--is presented. Also shown is the computed tomography evaluation of splint therapy, which has not been dealt with in other publications.

A subtraction technique in conventional angiography.

A subtraction technique is described for conventional angiography by which a superimposed vessel can be removed, allowing exact visualization of the area in question. The method is easy, requires only standard subtraction apparatus, and obviates the need for additional contrast material injections.
