Diabetic foot ulcers, "biomechanics" theory

According to the American scholar reported that diabetic foot ulcers are usually associated with two kinds of structural abnormalities of foot (tight Achilles tendon and thumb activities restricted) closely related to correct the two kinds of exceptions can help reduce or even eliminate foot wounds and ulcers. St. Paul's Hospital, Dr. Troy Boffeli and colleagues noted that most patients with newly diagnosed diabetic ulcers are abnormal foot biomechanics. The researchers selected 26 patients (33 feet) thumb incipient ulcer patients studied. Ulcer was found in almost all patients are located in the joints between the toes toe midface, accompanied by gastrocnemius muscle movement and the limited outreach thumb.

The researchers believe that inspections should include the patient's biomechanical evaluation, treatment, including surgical or conservative ways to reduce abnormal pressure on the thumb. In addition, most due to ulcers in patients receiving the thumb amputation within a year had a second amputation, bio-mechanical anomalies are caused by the first time an important factor in ulcer, if not corrected, for the first time after an amputation can also cause ulcers.

The researchers noted that most patients with diabetes associated with the Charcot ankle nerve arthritis, joint instability and dislocation, so they use the foot pads of the 13 patients with Charcot ankle joints fixed, in order to avoid further bone and soft tissue degradation, The main method is the first line of the Achilles tendon lengthening the foot to ease tension, and then a stable joint with plantar pad.

Boffeli Dr. noted that the current treatment of patients occurred without a re-fracture, soft tissue injuries and ulcers. However, the effect of treatment still need to 5-year follow-up study to further confirm.
