          Abstract

          Ten-year old boy with an 8-month history of limping for pain in the dorsomedial region of the right midfoot. At examination, there were signs of local swelling and tenderness to palpation, as well as antalgic gait with internal rotation. X-ray results showed widening of the proximal epiphysis of the first metatarsal. One month later, local fragmentation with hypodense and sclerotic areas was observed. MRI showed fragmentation, sclerosis, and collapse in the proximal epiphysis consistent with avascular necrosis of the proximal epiphysis of the first metatarsal bone. Patient was only recommended to avoid any physical activity that could increase the load on the foot, without pharmacological treatment. Symptoms spontaneously subsided over the course of six weeks and local pain disappeared after four months. Four years later, the patient remains asymptomatic, playing sports.

          A high index of suspicion is needed to avoid superfluous diagnostic tests, as it is a self-resolving lesion.

          Resumen

          Paciente varón de 10 años edad con cojera de 8 meses de evolución por dolor en la zona dorsomedial del antepie derecho. Presentaba inflamación local, dolor local y marcha antiálgica con rotación interna. No existían signos de flogosis, erosiones, eritema o fiebre. La radiografía mostraba ensanchamiento de la epifisis proximal del primer metatarsiano. Un mes después se podía observar fragmentación, esclerosis y colapso en radiografía y en resonancia magnética compatible con necrosis avascular de la epífisis proximal del primer metatarsiano. Se prescribió evitar actividades físicas con carga en el pie. Los síntomas remitieron espontáneamente en las siguientes seis semanas y el dolor local lo hizo tras cuatro meses. Cuatro años más tarde permanece asintomático, realizando deporte.

          Es una causa excepcional de cojera en la infancia. Se necesita un alto índice de sospecha para evitar realizar pruebas complementarias superfluas dado que es una entidad autoresoluble.

          Intraosseous pressure in Kienböck's disease.

          Intraosseous pressure was measured in the lunate of 10 patients undergoing surgery for Kienböck's disease. Using the styloid process of the radius and the capitate as reference points of bone pressure, I found a stasis rather than arterial insufficiency in the lunate. This pattern was observed regardless of the stage of the disease according to Ståhl and regardless of the finding by technetium TC 99m-methylene diphosphonate scintigraphy. The significance of this finding is still unknown but questions the current concept that Kienböck's disease is caused by arterial insufficiency, because these results imply an interruption of the blood flow as a result of venous congestion.

            Avascular necrosis of the intermediate cuneiform bone.

            We present a case of avascular necrosis of the intermediate cuneiform bone in a skeletal immature patient with a spontaneous recovery following conservative treatment. We discuss the aetiology and options of treatment.

              Assessment of etiologic factors in the development of Freiberg's disease.

              The etiologic factors in the development of Freiberg's disease are assessed in a consecutive series of 31 patients (33 feet). No evidence was found for the commonly held view that the condition is precipitated by trauma (in only 5 feet (15%), was there a history of injury to the foot). Similarly, pedobarographic studies failed to show high pressure at the affected metatarsal head. However, in 28 feet (85%), the affected metatarsal was the longest in the foot. The importance of this and other possible etiologic factors is discussed.
