Política

Subtalar arthroereisis is considered investigational as there is insufficient evidence to support a general conclusion concerning the health outcomes or benefits associated with this procedure.

Descripción/Antecedentes

Subtalar arthroereisis has been performed for more than 50 years, with a variety of implant designs and compositions. The Maxwell-Brancheau Arthroereisis implant is the most frequently used, although other devices such as the HyProCure^® subtalar arthroereisis implant, and Kalix^® devices are also available. The Maxwell-Brancheau Arthroereisis implant is designed to be reversible and easy to insert, while the additional advantage is that it does not require bone cement. In children, insertion of the Maxwell-Brancheau Arthroereisis implant may be offered as a standalone procedure, although often used in combination with other procedures to correct additional deformities.

Regulatory Status

A number of implants have been cleared for marketing by the U.S. Food and Drug Administration through the 510(k) process, and are summarized in Table 1. In general, these devices are indicated for insertion into the sinus tarsi of the foot, allowing normal subtalar joint motion while blocking excessive pronation.

Fundamento

Summary of Evidence

For individuals who have flatfoot who receive STA, the evidence includes mainly single-arm case series and a small nonrandomized controlled trial comparing STA with lateral column calcaneal lengthening. Relevant outcomes are symptoms, functional outcomes, and quality of life. The small nonrandomized comparative trial (n=24 feet) is considered preliminary, and interpretation of the case series evidence is limited by the lack of adequate comparators in addition to STA, creating difficulties in determining the extent to which each modality contributes to the outcomes. Another limitation of the published data is the lack of long-term outcomes, which is of particular importance because the procedure is often performed in growing children. Although some authors have reported rates of symptom improvement, the current evidence is insufficient to determine the effects of the technology on health outcomes.

For individuals who have talar subluxation joint dislocation who receive subtalar arthroereisis, the evidence consists of 1 prospective, single-arm study of talocalcaneal stabilization using HyProCure^®. Relevant outcomes are symptoms, functional outcomes, and quality of life. Although improvements in pain and function were observed, the current evidence on the use of subtalar arthroereisis for treatment of talar subluxation joint dislocation is insufficient to draw conclusions about treatment effectiveness. The evidence is insufficient to determine that the technology results in an improvement in the net health outcome.

Definiciones

Calcaneus is the largest of the tarsal bones situated at the lower and back part of the foot forming the heel.

Talus is the ankle bone; the bone of the tarsus which articulates with the tibia at the ankle.
