Subtalar arthroereisis is a common treatment for symptomatic pes planus, also known as flatfoot. There are two forms of pes planus: rigid flatfoot (RFF) and flexible flatfoot (FFF). The symptoms of the former typically necessitate surgical intervention[1]. The latter may manifest fatigue or pain, but is typically asymptomatic[1].

---|---|
Specialty | Orthopaedics |
Uses | Treating flexible flat foot |
Complications | Pain in sinus tarsi, implant extrusion, oversized implants, synovitis, infection, and peroneal spasm. |
Recovery time | Plaster fixation might be needed after surgery, non-weight-bearing exercises could be initiated around 3 weeks after surgery, partial weight-bearing function exercises after 6 weeks, resume to sports within 12 months. |
Outcome | Correcting the excessive subtalar eversion and restore the subtalar joint towards a neutral position. |
Subtalar arthroereisis is considered as the last resort for treating FFF in cases when conservative measures fail[2]. This is accomplished by putting an implant into the sinus tarsi to prevent excessive eversion of the subtalar joint and improve talus alignment relative to the calcaneus and navicular. This treatment is considered minimally invasive and joint sparing[3].
Complications associated with subtalar arthroereisis include undercorrection (due to the use of undersized implants), sinus tarsi pain, and implant extrusion. Less common complications include overcorrection caused by oversized implants, synovitis, infection, and peroneal spasm. Nerve injury can also occur as a complication but can be avoided with careful procedural execution.
Subtalar arthroereisis allows for the removal of the implant in case of postoperative complications while still maintaining the correction achieved for flat feet. The surgery also allows patients to bear weight right after the treatment.
