REPLACEMENT OF PROXIMAL INTERPHALANGEAL JOINTS IN HAMMER TOE DEFORMITY

Objective: to assess the results of Hammertoe Implant Procedure (HIP) in the treatment of hammer toes deformation. 28 operations were carried out in 16 patients aged 26 to 58 years with stage II-III (according to the classification of MI Kuslik) of hammer toes from September 2009 to March 2011. In 50% of them surgeries were performed on one foot, in the second half - on two feet. Mean duration of follow-up was 12.4 months, range 6-21. Results: evaluation of the results was carried out by scale of AOFAS. A significant improvement was noted after HIP: in average score before surgery - 47, in the postoperative period - 92. In evaluating the average preoperative pain score was 24.3, postoperative - 36.0 (complete absence of pain is estimated to be 40 points). Improving the function of the foot with an average of 19 before surgery after surgery reached 41 points, while the position of the fingers (the alignment of the foot and toes) is changed from the average value of 2.4 to 12.4 after surgery. Conclusion. Analysis of results showed the effectiveness of the HIP method in the treatment of hammertoe 2-3 fingers. HIP has allowed to achieve good functional and cosmetic results in early and the follow-up postoperative period. In our view, HIP with complex deformations forefoot can be used as an adjunct to other types of reconstructive surgery on the anterior part of the foot, and cases with recurrent strains hammer toes after surgery, HIP can be operation of choice.
