Objective:

To analyze the clinical results of metatarsalgia treated with percutaneous distal metatarsal metaphyseal osteotomies (DMMO).

Material and methods:

Prospective and continuous study of 29 patients with isolated unilateral mechanical metatarsalgia, operated on with DMMO, with a mean follow-up of 38 months. The mean age of the patients was 58 (range: 50-67) years and only two men. We use the AOFAS score, we obtained the digital and metatarsal formulas on the X-rays. We record the subjective assessment of the surgeon and the patient at the end of the treatment.

Results:

The improvement in the final score exceeded 80 points in all cases (p = 0.000), with a significant improvement in pain (p = 0.000) and calluses (p = 0.000), improving metatarsal-phalangeal joint stability and interphalangeal and metatarsal alignment. The type of footwear did not change after surgery, we found no variation in mobility, neither in the metatarsophalangeal joints (p = 0.382), nor in the interphalangeal joints (p = 0.672). After surgery increased the square foot morphology (p = 0.027) but the metatarsal formula underwent few modifications. Patients and surgeons were in 96% of the cases «very satisfied» or «satisfied».

Conclusion:

DMMO achieves a high degree of satisfaction in patients and in the surgeon, pain and hyperkeratosis under the head of the painful metatarsals disappear and that significantly improves the functional capacity of patients.
