The Opening Base Wedge Osteotomy and Subsequent Lengthening of the First Metatarsal: An In Vitro Study

Double First Metatarsal and Akin Osteotomy for Severe Hallux Valgus

“…The degree of lengthening is proportional to the size of the opening wedge and the plane of the osteotomy and varies from 1% to 2.8%. 3 The Lapidus procedure is technically challenging. Revision rates tend to be higher than those for other techniques and are reportedly up to 13%.…”

Second Metatarsal Transfer Lesions Due to First Metatarsal Shortening After Distal Chevron Metatarsal Osteotomy for Hallux Valgus

“…4 To prevent the shortening of the first metatarsal during hallux valgus surgery, opening wedge osteotomy, distraction osteotomy, and intentional depression of the first metatarsal head has been suggested. 5,14 However, we did not attempt to lengthen the first metatarsal or displace the distal metatarsal head in the plantar direction. Nonetheless, there was no significant correlation between the extent of first metatarsal shortening and the occurrence of second metatarsal transfer lesions.…”

Change in First Metatarsal Length After Proximal and Distal Chevron Osteotomies for Hallux Valgus Deformity

“…Because the PCMO is the osteotomy in which a lateral translation of the distal fragment is performed, accompanied by an opening wedge (28), it has been reported that the first metatarsal bone length was shortened by a small margin (2) or lengthened to some degree (29). Shortening of 1 to 2 mm can occur owing to the thickness of the microsaw blade and shaking of the blade while the osteotomy is being performed.…”
