A Review of 51 Talonavicular Joint Arthrodeses for Flexible Pes Valgus Deformity

Isolated talonavicular joint arthrodesis through minimal incision surgery

“…Since the talonavicular joint has been described as a part of the talo-calcaneal-navicular complex, isolated TNA was proposed as an effective method to treat flatfoot deformities; nevertheless, the procedure was further developed and expanded to a wide variety of rearfoot pathologies [1][2][3]9,10]. It is currently being used to treat traumatic, rheumatoid, and degenerative isolated talonavicular arthritis, posterior tibial tendon deficiencies, and pes valgus deformities, as well as congenital deformities and neuromuscular diseases [1][2][3]5,[11][12][13][14][15][16][17][18].…”

“…It is currently being used to treat traumatic, rheumatoid, and degenerative isolated talonavicular arthritis, posterior tibial tendon deficiencies, and pes valgus deformities, as well as congenital deformities and neuromuscular diseases [1][2][3]5,[11][12][13][14][15][16][17][18]. We used isolated TNA by MIS, fundamentally for patients with precarious soft tissue, but without malalignment of the hindfoot or peritalar destabilization [19].…”

“…Isolated talonavicular arthrodesis (TNA) has demonstrated to provide satisfactory pain relief and to be an appropriate action to control progression in cases of flatfoot deformity [1][2][3]. In spite of the above, orthopedic surgeons are faced with a significant rate of osseous non-union after conventional surgery and screw or plate fixation [1,4,5]. Additionally, in many patients with indications for TNA, soft tissues are in a poor condition because of previous surgeries.…”

Osteoarthritis of the talonavicular joint with pseudarthrosis of the navicular bone: a case report

“…Most of the literature addresses patients with either inflammatory arthritis or adult acquired flat foot [4,5,7-11]. Main reported that the fracture of navicular was caused by shearing forces between the cuneiforms and the talar head, and triple arthrodesis was effective for persistent symptoms [12] while Chen maintained that isolated talonavicular arthrodesis provided both pain relief and functional improvement in traumatic arthritis [3].…”

“…Isolated arthrodesis for talonavicular joint has usually been performed for pes valgus deformities, congenital deformities, neuromuscular diseases, and arthritic conditions, including inflammatory, degenerative, or post-traumatic arthritis [3-11]. …”
