Metatarsophalangeal Instability (Subscribe)  

this procedure allows long toe flexors to behave like intrinsic muscles producing active plantar flexion at MP joints & extension at IP joint;

Metatarsophalangeal joint dysfunction (MPJ) is one of the more common presentations that podiatrists see in practice. With this in mind, these authors offer pertinent pearls on the Weil osteotomy and weigh the benefits of hybrid screw fixation in facilitating improved outcomes.

Pain in the second MTP with synovitis and instability was first described in 1985 by Mann et al, who considered that the instability was due to synovitis of uncertain origin, perhaps associated with impingement from hallux valgus. Several relatively small studies have elucidated this problem further.

Instability and synovitis of the lesser MTP joints is a common cause of forefoot pain. Peck et al's (2006) series of 164 patients represented 26% of the patients presenting to their clinic with metatarsalgia.

Lesser Toe Problems
A number of abnormalities may need to be addressed: there is almost always a hammertoe deformity
instability of the MTP joint with a partial or full thickness plantar plate tear (plain or MR arthrography, or ultrasound, can help distinguish partial from full thickness tears)
in a few patients, fixed...
