ABSTRACT

Frieberg’s disease is a chronic painful condition characterized by avascular necrosis of metatarsal head. With this case report, we aimed to analyze the gait pattern of a case presented with Frieberg’s disease.

A 20-year-old female patient (body weight: 50 kg, height: 1.64 m, body mass index: 18.5 kg/m2) with a known Frieberg’s disease during the last 6 years is presented. Her physical examinations showed no anatomical deformity of the foot such as hallux valgus or pes planus. The diagnosis of chronic stage Frieberg’s disease was verified by a conventional posteroanterior X-ray imaging of foot. Gait analysis was performed during a painless period after physical and medical therapy. The average pressure distribution during stance phase was altered due to longterm protective behavior. There was a larger foot rotation on the affected side compared to the intacted side.

We considered that this gait pattern is not forced as in the primary pathologies or compensatory. Rather it may be accepted as volitional.
