SYNONYMS - Flat Feet - Pes Planovalgus - Fallen Arches - Pronation of feet DEFINITION Collapse of medial longitudinal arch, with the entire sole of the foot coming into complete or near-complete contact with the ground.
ANATOMY OF MEDIAL LONGITUDINAL ARCH Formed by the Calcaneum, Talus, Navicular, three Cuneiforms & three Metatarsals. Characteristic feature is RESILIENCY ( Capacity to recover quickly from any injuries) Factors maintaining the Medial Longitudinal Arch : BONE- Sustentaculum Tali supports the head of Talus. LIGAMENTS- a) Spring Ligament – provides dynamic support to head of talus. b) Interosseous Lig. – connecting adjacent bones. c) Interosseous Talo-calcanean Lig.
MUSCLES, TENDONS & APONEUROSIS- A] Acting as Slings [ suspension of arch from above] Tibialis Posterior Tendon : *Provides Dynamic support to Head of Talus *Suspends the arch from above. Tendon of Flexor Hallucis Longus : *Stretches the arch *Supports Calcaneus & Talus B] Acting as Tie Beams [preventing separation of the pillars] The medial part of plantar aponeurosis + Abductor Hallucis assisted by Flexor Hallucis Brevis – acts as tie beam to maintain the height of the medial longitudinal arch.
FLAT FOOT RESULTS IN – *Relatively over mobile foot (which requires muscular contraction to support the arches during standing ) *Increased weight bearing on the 2nd to 4th metatarsal heads ( plantar callus formation ) *Weight-bearing pronation in erect standing posture causes medial rotation of tibia ( may affect knee joint function )
BIOMECHANICS TWO TYPES- A) Rigid Flat Foot – MLA is absent in Non-weight bearing, Toe Standing, and in Normal weight bearing situation. B) Flexible Flat Foot – MLA is reduced during Normal weight bearing but reappears during Toe Standing and Non-weight bearing situation • Depression and pronation of the Calcaneus and depression of the Navicular bone • Tension in spring ligament • Lengthening of Tibialis Posterior Muscle ESTIMATION OF EXTEND OF FLAT FOOT – Note the location of navicular bone in relation to the head of first metatarsal. **Normally the Navicular bone is intersected by the Feiss Line. In case of flat foot, the Navicular bone is depressed ( i.e. it lies below the Feiss Line)
COMPONENTS OF FLAT FOOT Forefoot Abduction & Supination Talar head Displaced medially, anteriorly, and downwards Calcaneum Everts, dorsiflexes – hindfoot is in valgus Navicular Subluxates dorso-laterally
SECONDARY CHANGES • Navicular , Cuneiform, Cuboid becomes wedge shaped, with apex directed dorso- laterally. • Plantar, Spring and Deltoid ligaments are stretched. • Anterior, Pọsterior Tibial tendons & plantar muscles are stretched whereas the Achilles tendon & Peronei become shortened. • Callus develops over the medial bony prominences.
RADIOLOGICAL FEATURES • Collapse of the longitudinal arch • Hind foot Valgus • Forefoot Abduction
ETIOLOGY Rigid flat foot Flexible flat foot Developmental Hypermobile ( ligamentous hyperlaxity ) Neurogenic CONGENITAL FLAT FOOT ACQUIRED FLAT FOOT Pes planovalgus Adult Flexible Flat Foot Congenital Vertical Talus Tarsal Coalition Tendon Dysfunction Iatrogenic Arthritic Charcot Foot / Neuromuscular Flat Foot

OBJECTIVE ASSESMENT OBSERVATION • POSTURE - foot posture in standing and arch posture • Deformity - is there any deformity present such as bunions, hammer toes, claw toes, calluses, hindfoot valgus etc PALPATION • Joint Lines • Medial and lateral ligament • Achilles tendon, peronei and other extrinsic muscles
GAIT Gait Analysis - walking normally, on insides and outsides of feet, walk on heels and toes, in a straight line, running (particularly if pain present on running ) SR.N O. TITLE AUTHOR METHODOLOGY CONCLUSION 1. Kinematic Analysis of the Lower Extremities of Subjects with Flat Feet at Different Gait Speeds Myoung- Kwon Kim, Yun- Seop Lee This study determined the difference between flat feet and normal feet of humans at different gait velocities using electromyography (EMG) and foot pressure analysis. [Subjects] This study was conducted on 30 adults having normal feet (N = 15) and flat feet (N = 15), all of whom were 21 to 30 years old and had no neurological history or gait problems. [Methods] A treadmill (AC5000M, SCIFIT, UK) was used to analyze kinematic features during gait. These features were analyzed at slow, normal, and fast gait velocities. A surface electromyogram (TeleMyo 2400T, Noraxon Co., USA) and a foot pressure analyzer (FSA, Vista Medical, Canada) were used to measure muscle activity changes and foot pressure, respectively. Because muscle activation has a tendency to increase with an increase in gait velocity, we hypothesized that the lower extremity with a flat foot requires more work to move due to the lack of a medial longitudinal arch, and consequently pressure was focused on the 2nd–3rd metatarsal area during the stance phase Article link -- https://doi.org/10.1589/jpts.25.531

SPECIALTEST “Too many toes sign” • Navicular Drop Test • Toe Raising Test • Fore-Foot Heel Alignment • Jack’s Test ( Hubscher’s maneuver ) • Silfverskiöld test
Special Test: Functional or Structural Pes Planus PROCEDURE: • Therapist observes ( and compares) the orientation of the patient’s MLA while doing each of the following: a. Patient stands straight with both heels and toes on the ground b. Patient stands with just the toes on the ground c. Patient sits on the table POSITIVE TEST: • Functional Pes Planus = if MLA is restored when the patient is either standing on the toes or seated = due to muscle or ligament weakness • Structural Pes Planus = if MLA remains flat when the patient is standing on toes and when seated.
INVESTIGATION X-RAY : • AP and Lateral Views of the foot is taken to evaluate the severity of deformity. • Special View – 45 degree eversion oblique for accessory navicular bone. • AP standing view is to assess Heel Valgus ( Talo-calcaneal angle > 35 degree is associated with increased heel valgus ) CT SCAN : Accurately defines anatomy of subtalar joint, allows surgical planning if involved.
DIAGNOSIS A] Collapse of the longitudinal arch. *Meary’s angle Long axis of Talus should nearly bisect the Navicular & long axis of First Metatarsal through it’s shaft ( on standing lateral X-ray ) Grades – Normal – 0 degree Mild – 0 to 15 degrees Moderate – 15 to 40 degrees Severe – > 40 degrees
*Calcaneal Pitch is decreased Normal – 17 to 32 degrees
B] Hind foot Valgus : *AP Talo -calcaneal Angle – Angle formed by the intersection of a line bisecting the head of the TALUS and a line running parallel with the lateral surface of the CALCANEUS. Normal Range is 15 – 30 ° Abnormally increased angle > 30 degrees indicates Hind Foot Valgus in pes planus
C] Forefoot Abduction : Lateral subluxation of the navicular on the talus is indication of forefoot abduction
PROBLEM LIST BODY STRUCTURE & FUNCTION ACTIVITY LIMITATION PARTICIPATION RESTRICTION Pain along the arch and dorsum of foot Inability to weight bear Difficulty while walking, standing and running Hind foot Stiffness Unable to invert or evert while weight bearing Gait Deviation Restricted ROM Walking Limitations Difficulty in daily activities
SHORT TERM GOALS LONG TERM GOALS To relieve Pain Pain free Ambulation To reduce stiffness Gait training To increase ROM at Talus-crural joint, Subtalar joint, Calcaneo-cuboid joint and Transverse tarsal joint. Strengthening of weak muscles To mobilize the callus formed Argonomics
MEDICAL MANAGEMENT • Analgesics & NSAIDs are the common pain relieving medications.
CONSERVATIVE MANAGEMENT 3-9Years : • Conservative Management • No Surgery • Custom orthosis inserted with leather, cork, propylene. • Physiotherapy Physiotherapy – Gastrocnemius Stretching, Tibialis posterior and Intrinsic muscles Strengthening . 10-14Years : • If there are No symptoms – No treatment is needed. • Symptomatic – Initially conservative management - Orthosis - Physiotherapy - Surgery
FOOT ORTHOSES
INDICATION FOR SURGICALTREATMENT 1. Persistent pain and Ulceration or Callus under the head of the plantar flexed talus and interferes with normal daily activities. 2. Rigid and painful flatfoot. 3. To prevent progression in neuropathic ( charcot joint ) 4. Tibialis posterior dysfunction.
OPERATIVE PROCEDURES 1. Achilles tendon or gastrocnemius fascia lengthening 2. Evans Calcaneal Lengthening osteotomy 3. Talonavicular reduction and pinning 4. Talectomy 5. Triple Arthrodesis
Achilles tendon or gastrocnemius fascia lengthening • TA Lengthening – Percutaneous & Z lengthening • Gastrocnemius Recession
Evans Calcaneal Lengthening osteotomy • Lengthening of lateral column of the foot by inserting bone graft and calcaneocuboid fusion.
Triple Arthrodesis • Usually done after the age of 12-13 years. • Has a 50% failure rate in children under 10 years of age. Joints fused are : • Subtalar joint. • Calcaneo - Cuboid joint. • Talo Navicular joint.
COMPLICATIONS OF SURGERY • Non-union • Degenerative joint disease • Avascular Necrosis • Lateral Instability • Stiff Foot
POST OPERATIVE PHYSICALTHERAPY MANAGEMENT DAY 1-7 POST OP • Patient education & advice • Education of precautions & contra- indications • Non weight bearing immobiliztion • Bed Exercises : *Upper limb exercises to stimulate the cardiac function * Maintenance of non-operated leg 2WEEEKS POST OP • Removal of cast • Replaced with posterior orthosis, a removable cast boot or CAM boots that allows free plantarflexion but restricts dorsiflexion to -20 degree. • Partial weight bearing ambulation with bilateral axillary crutches • Prevent stiffness
2-4WEEKS POST OP • Same CAM Orthosis continued. • Weight bearing as tolerated in walking boot or CAM orthosis, crutches as needed 4-6WEEKS POST OP • CAM orthosis that allows free plantarflexion but restricts dorsiflexion to 10 degree ( week 4) and 0 degree (week 5). • Full weight nearing in walking boot. 6-8WEEKS POST OP • CAM orthosis that allows free plantarflexion but restricts doriflexion to 10 degree (week 6). • Wean from CAM orthosis to shoes with 1 to 1.5cm bilateral heel lift (week 7). • Full weight bearing to functional brace or shoe with heel lift. 8WEEKS POST OP • Wean from heel lifts by 10 weeks. • Full weight bearing in regular shoe without lifts by 10 weeks.
POST OP EXERCISES STRETCHING EXERCISES • Initiate AROM dorsiflexion within the protected range by week 3. • Limit DF to no more than 10 degree beyond neutral until 8 weeks after surgery. • Progress to full ankle DF by 12 weeks. • Initiate weight bearing stretches in sitting with feet on the floor, a low incline wedge (< 10 degree). • Begin standing stretches in bilateral stance with knees bent, only if pain free, which is accomplished with a modified runners wall stretch or a low incline (<10 degree) wedge. RESISTANCE EXERCISES • Begin strengthening exercises for ankle and foot musculature in non weight-bearing positions against low loads before progressing to closed chain exercises against body weight. • Initiate heel raises in a seated position with gradual addition of external resistance before progressing to bilateral heel raises in standing. • Progress heel raising/lowering exercises from bilateral to unilateral only if performed pain free by 10 to 12 weeks post-op.
