Phalanx; Dislocation Toe(S) clinical trials

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.

Intramedullary Resorbable Fixation System Versus K-wire for the Treatment of Lesser Toe Deformities

Start date: May 1, 2019
Phase: N/A
Study type: Interventional

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.
