Hallux Valgus Osteotomy / Lapidus Arthrodesis
Hallux Valgus Osteotomy / Lapidus Arthrodesis
Lapidus arthrodesis is a surgical procedure used to treat severe bunions, also known as hallux valgus deformity by cutting and realigning the toe's bones. In cases requiring significant realignment or with bone loss, an allograft wedge can be inserted into the created gap during osteotomy to maintain alignment, support healing, and enhance the procedure's success.
- This study found no significant difference in union rates between Lapidus arthrodesis cases that used an allograft bone wedge (90%) and those that did not (97%), but there was a significant difference in union rates when comparing the use of two crossed compression screws (85%) to a medial locking plate with a single transarticular screw (98%). The research highlights the importance of robust fixation when using an allograft bone wedge, and demonstrates that it offers a valuable option in cases requiring extensive bony resection due to severe deformity, or where there's a considerable length discrepancy between the first and second metatarsal.
- This study examined the use of an allograft bone wedge in Lapidus procedures, finding that the use of an allograft bone wedge, particularly with a medial locking plate and intra-articular compression screw, can aid in decisions regarding bony resection, potentially reduce the risk of metatarsalgia due to shortening, and allow for more significant corrections while maintaining satisfactory union rates.
