[Clinical pedographic radiological findings after basal valgus osteotomy of metatarsal 1--a prospective study].
OBJECTIVE
This study investigated the influence of valgusizing base wedge osteotomy of metatarsal 1 (MT 1) subsequently on the entire forefoot.


METHODS
Pre- and post-operatively 22 cases were investigated between 1998 and 2000 both clinically and radiologically with pedographic analysis in 20 of these cases.


RESULTS
According to the Kitaoka Score we could establish preoperative 37 and postoperative 72 out of 100 possible points. Following the MT 1-base wedge osteotomy with a distal soft-tissue procedure, the central forefoot region (MT 2/3) showed reduced pressure-induced pain, unchanged callus development, and reduced maximum load pressure. When the Plus-Index (MT 1 longer than MT 2) could be preserved in the valugusizing MT 1-base wege osteotomy, the metatarsalgia in the central forefoot region not only improved generally, but also the maximum loading pressure was clearly reduced. In cases with a post-operative Minus-Index (MT 1 shorter than MT 2), as well as in those Plus-Index cases undergoing a Keller procedure in the valgusizing base wedge osteotomy, the elevated pressure values in the central forefoot region persisted.


CONCLUSIONS
In valgusizing MT 1-base wege osteotomy with preservation of the Plus-Index (MT 1 longer MT 2), metatarsalgia can be improved and the maximum loading pressure in the central forefoot can be reduced.
