“…The biggest concern in previous publications is a relatively high nonunion rate, up to 12% (Table 1) [2,10,11,13,18]. However, most of these studies with high nonunion rates involved varied joint preparation and different types of fixation [2,3,7,8,10,13,16,18].…”

Background: The modified Lapidus procedure is widely used to correct hallux valgus but has been reported with high nonunion rates. In this study, we retrospectively reviewed the nonunion rate of the modified Lapidus procedure performed with rigid cross screw fixation, meticulous joint preparation, and shear-strain-relieved calcaneal bone graft. Questions/Purposes: Does the performance of the Lapidus procedure with rigid cross screw fixation, complete joint preparation, and shear-strain-relieved calcaneal bone graft achieve higher union rates than currently reported? If nonunion does occur, what is the clinical course? Methods: We reviewed both radiographic and clinical results of the modified Lapidus procedure with the above technique in 171 patients (182 feet). Evaluation included age, gender, tobacco use, diabetic status, and radiographic analysis at least 3 months postoperatively. Results: The modified Lapidus procedure described above resulted in a union rate of 97.3% (177 of 182 feet). Three of the five feet with radiographic nonunions were clinically symptomatic. Conclusions: The union rate of the modified Lapidus procedure is higher than previously reported when performed with rigid cross screw fixation, meticulous joint preparation, and shear-strain-relieved bone graft. Nonunion of the first tarsometatarsal joint should be considered an infrequent occurrence.

“…Although Lapidus originally stabilized the arthrodesis site with catgut suture, multiple fixation constructs have evolved to enhance the mechanical stability of the fusion interface. Static fixation constructs using partially threaded screws, Steinman pins, H-plates, and crossed screws have been reported both clinically 3,[6][7][8][9][10][11][12][13] and in cadaveric and synthetic models. 2,4,[14][15][16][17][18][19] Cohen et al 18 compared crossed screws to a locking H-plate in a cadaveric model.…”

“…17 Classically, the In case of stable fixation and good initial positioning of the first metatarsal, the nonunion can be revised by first tarsometatarsal athroscopy. 11 As an arthroscopic procedure, advantages associated with this technique include better cosmesis, better visualization, limited bone resection and less soft-tissue dissection (Table 2).…”

Revision arthrodesis is indicated in symptomatic nonunion of the first tarsometatarsal joint. Revision by first tarsometatarsal arthroscopy cannot deal with the dilated screw tract and associated bone cysts. Revision by bone endoscopy is indicated in symptomatic nonunion of the first tarsometatarsal joint, which is previously fixed by transarticular screw along with loosening of the screw and bone cyst formation. The screw tract makes up the portal tract, with the proximal and distal ends of the tract corresponding to the proximal and distal portals, respectively. In this technical note, we describe zonal debridement and bone grafting of the bone cysts, nonunion site, and the screw tract via the bone endoscopy. This can resolve all the co-pathologies of nonunion of the first tarsometatarsal fusion.
