She had some forefoot supination that was felt to cause a valgus moment at her ankle while she was striding. After careful analysis of her condition, it was agreed that she could, with use of a semirigid orthotic, run one race that she and her trainer felt was essential for her preparation for the World Championships. The plan was that, following this event, she would then do easy training for two and a half weeks before her next big race.
A bone scan or magnetic resonance imaging (MRI) usually will confirm the diagnosis before plain radiographic changes are evident.  Type I The head of the metatarsal (MT) dies and then heals by “creeping substitution” (Phemister). In this form it may heal completely, with little or no collapse, leaving the articular surface intact and almost as good as it was before the event occurred. Surgery often is not necessary. Type II The head collapses during revascularization and the articular surface settles and remains intact, but peripheral osteophytes form along the dorsal margin of the joint, limiting dorsiflexion.
After the torn spring ligament was exposed at its navicular insertion, the edges and thinned portions were debrided. The proximal medial aspect of the pole of the navicular was roughened, establishing a cancellous bleeding surface through which an osseous suture anchor was placed, thereby avoiding inadvertent talonavicular joint penetration. A splint was applied following surgery. This was replaced by a brace that was worn for 16 weeks. A heel lift was used for 6 to 8 weeks subsequently. Rehabilitation succeeded in permitting this athlete to resume his career and to set the American pole vault record on his repaired foot.
