Instruments and techniques can be used to release a first metatarsal for realignment. In some implementations, a techniques involves surgically accessing a sesamoidal ligament in a foot of a patient and advancing a guiding projection of a cutting instrument under the sesamoidal ligament. This can capture the sesamoidal ligament between the guiding projection of the cutting instrument and a cutting surface of the cutting instrument that is recessed relative to a distal end of the guiding projection. The techniques further involves cutting the sesamoidal ligament with the cutting surface of the cutting instrument.

First metatarsal lateral release instrument and technique

A variety of surgical procedures may be performed on the bones of the foot, such as on one or more lesser metatarsals of the foot positioned laterally of the first metatarsal. For example, a surgical procedure may involve cutting an end of one or both of a second metatarsal and an intermediate cuneiform and/or cutting an end of one or both of a third metatarsal and a lateral cuneiform. The tarsometatarsal joints defined be one or both sets of bones may be cut to treat an arthritic joint, metatarsus adductus, and/or other clinical condition. In any case, various surgical instruments can be utilized during a procedure to help increase the accuracy and repeatability of the procedure patient-to-patient, improving overall patient outcomes. For example, one or more cut guides, compressor-distractor devices, and/or other instruments designed to accommodate the specific anatomical conditions of the procedure being performed may be utilized during procedure.

Devices and techniques for treating lesser metatarsals of the foot

A metatarsus adductus technique may involve cutting an end of one or both of a second metatarsal and an intermediate cuneiform to create a wedge-shaped opening between the end of the second metatarsal and the intermediate cuneiform. The method may further involve cutting an end of one or both of a third metatarsal and a lateral cuneiform to also create a wedge-shaped opening between the end of the third metatarsal and the lateral cuneiform. The second metatarsal and the third metatarsal can then be moved in a transverse plane to close a metatarsus adductus angle. Movement of the second and third metatarsal may close the wedge-shaped openings forming during bone cutting. With the second and third metatarsals appropriately realigned, the clinician can fixate the moved position of the second metatarsal and the third metatarsal.
