After medializing calcaneal osteotomy for flexible flatfoot, children still showed higher arch index and more external foot rotation than matched controls, despite balanced plantar loading and similar stance timing; higher BMI independently raised arch index.
In patients with progressive collapsing foot deformity, greater hindfoot valgus malalignment, male sex, and higher BMI were associated with failure of nonoperative treatment and eventual surgery.
Double-pin versus single-pin calcaneocuboid joint fixation during calcaneal lengthening for pediatric flatfoot showed better maintenance of calcaneal pitch at 2 years but similar subluxation prevention.
Adolescent flexible flatfoot shows anteromedial forefoot loading; radiographic and dynamic assessments capture complementary, non-interchangeable aspects.
Static pronation (FPI-6) showed poor concordance with structural flatfoot or dynamic loading patterns, supporting multidimensional assessment for clinical evaluation.
Progressive Collapsing Foot Deformity. Is There Really a Johnson and Strom Stage I?
Reviews Johnson and Strom stage I posterior tibial tendon dysfunction, covering clinical diagnosis, causes, orthotic and surgical options, and possible prophylactic medializing calcaneal osteotomy in patients at high risk of progression.
This review examines subtalar arthroereisis for flexible progressive collapsing foot deformity in adults, noting generally improved clinical scores but unclear indications and sinus tarsi pain as the main complication.
Triple Arthrodesis for Adult-Acquired Flatfoot Deformity.
Review of triple arthrodesis for adult-acquired flatfoot, highlighting advances in imaging, fixation, and postoperative care for correcting the rigid planovalgus foot.
Flexible flatfoot in children and adolescents
Flexible flatfoot is normal in most children; pain-causing short Achilles tends improves with surgery combining osteotomy and lengthening.
Posterior Tibial Tendon Insufficiency: Which Ligaments are Involved?
MRI study of 31 patients found ligament involvement is extensive in posterior tibial tendon insufficiency, most often the spring ligament complex, so treatment should aim to protect these ligaments from progressive failure.
