Detailed Picture

It is unusual to find such extensive deformity of the navicular in a bilateral and symmetrical fashion. The apparent lack of significant trauma coupled with the patient's unremarkable medical history led the authors to an exclusionary diagnosis of spontaneous osteonecrosis. While changes are clearly evident on plain film radiography, computed tomography and magnetic resonance imaging provide the clinician with a more detailed picture of the extent of destruction.

Kirner’S Deformity

The distal phalanx in Kirner’s disease is abnormal and recognizable both clinically and radiologically. Despite previous investigation, the cause of these abnormalities is not clear. The current study seeks to evaluate the abnormal physis in Kirner’s deformity using radiological investigation, intraoperative observation and histopathological assessment in three clinical cases. Similarities with clinodactyly are described. Three patients with Kirner’s deformity underwent plain-film radiography and magnetic resonance imaging. Intraoperative observations were recorded, and histologic assessment of anatomically abnormal tissue was performed in all three cases. All three modalities of investigation (plain-film X-rays, magnetic resonance imaging and histological findings) were consistent and supported the intraoperative observation of cartilage abnormally situated anterior to the diaphysis and deep to the flexor tendon. There is thus evidence for the presence of an incomplete volar bracket or L-shaped physis in Kirner’s deformity, analogous with the C-shaped bracket found in clinodactyly.

Preceding Study

This preliminary study considers the advantage of magnetic resonance imaging over plain film radiography in assessing pin resorption and bone marrow regeneration over a 6-month period. The Orthosorb pin was used to fixate an Austin osteotomy in a patient and was followed with serial magnetic resonance imaging at scheduled intervals. This study expands on the preceding study in this issue of the Journal, which was carried out in the rat model.
