Outcomes
Primary Outcome Measures
Change of AOFAS MTP-IP for the lesser toes
Each measure is comprised of nine questions and cover three categories: Pain (40 points), function (50 points) and alignment (10 points). These are all scored together for a total of 100 points.
Secondary Outcome Measures
Change of Finger alignment.
X-ray in dorsal-plantar projection in load to measure the angle formed between the longitudinal axes of the proximal and middle phalanges. Good: 0-10º. (tb smartoe vs kw buried and the other from smartoe); Enough: 11-20º; or Bad:> 20º.
Change of visual analog scale
Heel pain intensity was referred to as 0-10, in which 0= no pain at all and 10= the worst pain possible
Level of Satisfaction
Satisfaction assessed by the scale.This is a self-administered scale of satisfaction with the procedure with 4 categories. The response categories consisting of very satisfied (4 points), somewhat satisfied (3 points), somewhat dissatisfied ( 2 points), and very dissatisfied (1 points).
Change of Foot health status questionnaire
Foot Health Status Questionnaire: The questionnaire to measure foot health related quality of life. The Foot Health Status Questionnaire Data Analysis Software obtain the scale scores for the domains of; Foot Pain, Foot Function, Footwear, General Foot Health Perceptions from respondent's answers on the questionnaire.The questionnaire does not providean overall score. To obtain these indexes, the responsesare analysed through computer software (FHSQ, version1.03). After processing the data, the software produces ascore ranging from 0 to 100. The maximum score is in-dicative of a person with excellent foot health, no painor discomfort and no difficulty or limitations in puttingon shoes, performing activities of daily life or work, with adequate functional capacity; a score of zero representsthe worst state of health for the foot.

5. Study Description
Brief Summary
Hammertoe deformity is one of the most common deformities in the foot and is characterized by dorsiflexion of the proximal phalanx at the metatarsal-phalangeal joint and a plantarflexion of the middle phalanx at the proximal interphalangeal joint. Surgical intervention for this type of deformity is indicated when the symptoms progress and conservative treatments are not enough, that is, when we are faced with a rigid painful deformity.Arthrodesis of the proximal interphalangeal joint temporarily fixed with a Kirschner wire is the most commonly used techniques.
Therefore, intramedullary fixation with a PLLA needle may be a good alternative. The use of biomaterial is gaining relevance in foot surgery, with polylactic acid being the most widely used due to its strength. Its total biodegradation requires a time of 16-24 months. No cases of foreign body reaction have been described with this type of osteosynthesis material, due to its characteristics similar to those of bone. Its only drawbacks are that it increases the complexity of the technique and that it increases the cost of the procedure. Being a flexible needle, it allows to leave a functional intraoperative claw. It maintains the functionality of the distal interphalangeal joint and carries a lower risk of infection by carrying osteosynthesis material on the outside.
The purpose of the present study is to prospectively collect clinical and radiographic outcomes of operative correction of hammertoe deformity using a fixation system of intramedullary device of polylactic acid versus a kirschner wire.
