Pediatric Flatfoot Deformity Case Study Evaluation and Management Frank A Luckino III DPM, Jeffrey C. Lupica DPM, Allan Boike DPM Department of Podiatry Pediatric flatfoot is not an uncommon patient presentation in clinical practice. A thorough history and physical examination of these children is Treatment of pediatric pes planus depends on the degree of deformity and Parents often become more concerned than the children themselves. Reports paramount. Standing exam and gait analysis is recommended. Body symptomatology. Initial treatment should consist of modifying activity and non- show that more than 30% of all newborns have a calcaneal valgus foot habitus and limb alignment should be noted as well (1). Radiographs in a steroidal anti-inflammatory medications as necessary (2). Stretching regimens deformity of both feet (5). As these individuals mature, the majority will weight-bearing fashion should be obtained (5). As a clinician, one needs to may be implemented if an equinus deformity is a cause for abnormal pronation become asymptomatic and not necessitate care. However, some patients will determine whether the deformity is pathologic or non-pathologic, rigid or and subsequent pes planus. Physical therapy should be started when muscle require conservative and or surgical treatment. The goal of the clinician is flexible, functional or nonfunctional, symptomatic or asymptomatic (1). weakness is observed. Orthotics, whether over-the counter or custom made, determine whether the deformity is rigid or flexible, painful or non-painful, and A calcaneovalgus foot deformity presents with a flexible, deformity which is may provide some relief despite limited level one studies (1). In an article by functional versus nonfunctional. Differential diagnosis includes calcaneal easily manipulated. The foot can be easily dorsiflexed and plantarflexed Evans in 2008, three randomized controlled studies were analyzed that valgus, congenital vertical talus, flexible flatfoot, accessory navicular, tarsal against the leg and subtalar joint range of motion is normal. This deformity evaluated the effect of foot orthoses on the pediatric flatfoot. One study showed coalition, and skewfoot. We present the case of a 5 year old male who is usually asymptomatic. Musculotendinous structures are normal in that children with juvenile rheumatoid arthritis treated with orthoses had a presented to our clinics with chronic foot pain and severe flatfoot deformity. length. There are no associated dislocations and is thought to result from reduction in pain and improved quality of life. Two other studies of children with The patient had no previous neuromuscular disorders or significant past intrauterine position. Orthotics and bracing may help alleviate symptoms typical pes planus and/or pronated foot type treated with orthoses versus medical history. The clinical and radiographic findings are reported and (5). Congenital vertical talus (CVT), typically presents with a symptomatic controls showed no significant difference in regards to foot type, motor skills, or treatment plan is outlined. deformity that is rigid in nature. “Rocker-bottom” appearance is common physical performance. However, the latter two studies did show a reduction in to the foot and is not amenable to reduction. The navicular is dorsally leg/foot pain though this was more of an observed rather than quantified result dislocated on the talus. The Achilles tendon is typically contracted (8). As reported in a Cochran Review orthotics should not be used in children posteriorly and extensor digitorum longus anteriorly. Treatment usually that have a asymptomatic flexible flatfoot as the deformity will reduce with age. consists of casting followed by surgery when conservative treatment fails Orthotics should only be used in children that are symptomatic. Referenced in (6). Stressed plantarflexion/dorsiflexion views are paramount in this same article, children who wear shoe gear often before the age of six have differentiating tarsal coalition, CVT, pediatric flexible flatfoot (1). a higher preponderance for a pes planus foot type than there unshod counterparts (4). On physical exam, vascular status was intact and neurological exam was normal. Dermatological exam revealed no relevant findings. On the Discussion: musculoskeletal exam, muscle strength was rated 5/5. Ankle joint ROM was Pediatric flatfoot deformity is an entity commonly seen in orthopedic and decreased with the knee flexed but full when extended.

Standing exam reveals bilateral pes that the majority of children will have a pes planus foot type that should resolve planus with an everted rear foot of approximately 15 degrees.
