Morton's neuroma is a benign neuroma of an intermetatarsal plantar nerve, most commonly of the second and third intermetatarsal spaces (between the second/third and third/fourth metatarsal heads; the first is of the big toe), which results in the entrapment of the affected nerve.
Morton's toe is the condition of having a first metatarsal bone that is shorter than the second metatarsal (see diagram). It is a type of brachymetatarsia. [1] This condition is the result of a premature closing of the first metatarsal's growth plate, resulting in a short big toe, giving the second toe the appearance of being long compared to the first toe.
One cause of metatarsalgia is Morton's neuroma. When toes are squeezed together too often and for too long, the nerve that runs between the toes can swell and get thicker. This swelling can make it painful when walking on that foot. High-heeled, tight, or narrow shoes can make pain worse. This is common in runners, particularly of long distance.
Traumatic neuroma follows different forms of nerve injury (often as a result of surgery). They occur at the end of injured nerve fibres as a form of ineffective, unregulated nerve regeneration; it occurs most commonly near a scar, either superficially (skin, subcutaneous fat) or deep (e.g., after a cholecystectomy). They are often very painful.
Mulder's sign is a physical exam finding associated with Morton's neuroma, which may be elicited while the patient is in the supine position on the examination table. The pain of the neuroma, as well as a click, can be produced by squeezing the two metatarsal heads together with one hand, while concomitantly putting pressure on the interdigital space with the other hand.
It is named after Jules Tinel. [ 3 ] [ 4 ] [ 5 ] It is a potential sign of carpal tunnel syndrome , cubital tunnel syndrome , [ 6 ] anterior tarsal tunnel syndrome [ 7 ] [ 8 ] and symptomatic neuroma .
Complex regional pain syndrome is uncommon, and its cause is not clearly understood. CRPS typically develops after an injury, surgery, heart attack, or stroke. [8] [12] Investigators estimate that 2–5% of those with peripheral nerve injury, [13] and 13–70% of those with hemiplegia (paralysis of one side of the body) [14] will develop CRPS.
If non-invasive treatment measures fail, tarsal tunnel release surgery may be recommended. Tarsal tunnel release is a form of a nerve decompression to relieve pressure on the tibial nerve. The incision is made behind the ankle bone and then down towards but not as far as the bottom of foot.
