We reviewed the medical records and radiographs of 35 patients (3 males, 32 females; mean age 40.8 years) who underwent isolated, modified Lapidus arthrodesis for forefoot pathology in 39 feet. The purpose of the review was to evaluate the structural radiographic changes of the medial longitudinal arch (MLA) following isolated arthrodesis of the first tarsometatarsal joint. Pre- and postoperative standardized measurements of sagittal plane views of the foot were assessed to examine change in the MLA construct. The talo-first metatarsal angle and medial cuneiform height both had statistically significant changes, 2.97 degrees (range, 0-11.5 degrees) and 3.44 mm (range, 0-13 mm) (P < .0001) respectively. Our findings suggest that the Lapidus arthrodesis may influence the medial longitudinal arch.

Joint arthrodesis is a very common surgical approach in foot and ankle surgery at various anatomic levels. Several techniques have demonstrated the ability to provide successful fusion with appropriate preparation of the joint in question. With that in mind, the joint preparation, regardless of approach or instrumentation, is consistently the most time-consuming.

Many fixation options exist for correction of a hallux valgus deformity with a first tarsometatarsal joint arthrodesis with pros and cons to each. Few have looked at utilizing a shape memory alloy staple made from nitinol for fixation. This study evaluates the effectiveness of a modified Lapidus technique using a nitinol (shape memory alloy) staple combined with a two-screw construct for first tarsometatarsal joint arthrodesis in correcting hallux valgus deformity.

Background: Titanium plantar plates have proven successful in the fixation of the first tarsometatarsal arthrodesis (TMT). However, a second surgery is typically needed for implant removal, and potential adverse effects, carried by the conventional implantations, are not uncommon. The purpose of this study was to determine whether a novel magnesium-based plantar plate system provides similar fusion stability to a titanium-based plantar plate system under various loading conditions.

: Hallux valgus (HV) is recognized as a triplanar deformity. A biplanar locking plate (BLP) system corrects this deformity through first tarsometatarsal joint (TMTJ) arthrodesis, with specialized reduction tools and cutting guides. Yet the optimal surgical technique and fixation construct for first TMTJ arthrodesis remains controversial.
