![]() ![]() dorsiflexion of the ankle, in contrast, will worsen the deformity if the hammer toe is due to contracture of FDL tendon, then plantar flexion of the ankle will straighten the toe it has been suggested that pressure on the plantar aspect of the metatarsal heads will cause toe extension in supple hammer toes distinguish between supple and fixed hammer toe determine if hammer toe is made worse w/ walking (hammer toes are usually accentuated by standing, when intrinsics are relaxed) look for callus formation over dorsum of PIP joint and/or at the volar tip of the toe (just under the nail) Subluxation and dislocation of the second metatarsophalangeal joint. Second metatarsophalangeal joint instability. Traumatic horizontal deviation of the second toe: mechanism of deformity, diagnosis, and treatment. taping of toes may prevent further deformity but will not reverse deformity w/ cross-over toe deformity look for tight medial collateral ligament, and plantar skin changes after it has subsided patient may be left with subluxated MTP joint & fixed hammer toes deformity w/ dorsal dislocation, there will usually be attenuation of the volar plate it usually subsides after 3 to 6 months, but may go on to frank dorsal subluxation if long metatarsal is a strong risk factor, and the EHL/EDL is the most important dynamic deforming force occurs spontaneously in women and results in pain and disability tends to involve second metatarsophalangeal joint ref: Definitions of hammer toe and claw toe: an evaluation of the literature main action of the EDL is to dorsiflex the phalanx, but can only do so when the phalanx is in a neutral or flexed position w/ MP joint contracture, contracture of EDL may prevent the MP joint from obtaining a neutral position in rare cases hammer toe deformity may be due to plantar fascia release less common causes are RA, cross over deformity, diabetes high heels and crowded shoe wear are also common causes long second metatarsal may be a predisposing factor when this is the case look for a dynamic deformity, ie., the hammer toe is worse when the patient stands or walks w/ severe hammer toe deformity, MP joint may go into hyperextension (distal joint usually stays supple) ![]() flexion deformity of PIP may be fixed or supple the hammer toe deformity is similar to the curly toe deformity but is not malrotated Hammer toe can also be found in Friedreich's ataxia (GAA trinucleotide repeat).- term describes abnormal flexion posture of PIP joint of one of lesser 4 toes Toe deformities can also be caused by muscle, nerve, or joint damage, resulting from conditions such as osteoarthritis, rheumatoid arthritis, stroke, Charcot–Marie–Tooth disease, complex regional pain syndrome or diabetes. Ill-fitting shoes are especially likely to push the toes out of balance. If the bend persists, then as the tendons and ligaments tighten (as they do if not stretched ), the bend may become permanent. The toe muscles work in pairs if the muscles pulling in one direction are much weaker than those pulling in the other direction, the imbalance can bend the toe. ![]() This is often found in conjunction with bunions or other foot problems (e.g., a bunion can force the big toe to turn inward and push the other toes). Having the toes bent for long periods of time can cause the muscles in them to shorten, resulting in the hammer toe deformity. Hammer toe most frequently results from wearing poorly fitting shoes that can force the toe into a bent position, such as high heels or shoes that are too short or narrow for the foot. Hammertoes and clawtoes have multiple causes. Causes Ī mallet toe is evident on the 3rd digit. Arthritis and diabetes may also increase the risk of foot deformities. Injuries to the toes, and being born with a big toe that is short in comparison to the second toe, increase risk. Women are at higher risk, due to the construction of women's shoes. Older people are more likely to develop hammer toes. Claw toe can affect the second, third, fourth, or fifth toes. Ĭlaw toe is another similar condition, with dorsiflexion of the proximal phalanx on the lesser metatarsophalangeal joint, combined with flexion of both the proximal and distal interphalangeal joints. Mallet toe is a similar condition affecting the distal interphalangeal joint. In the early stage a flexible hammertoe is movable at the joints a rigid hammertoe joint cannot be moved and usually requires surgery. A hammer toe or contracted toe is a deformity of the muscles and ligaments of the proximal interphalangeal joint of the second, third, fourth, or fifth toe bending it into a shape resembling a hammer. ![]()
