What is flat foot?
● Also known as Pes planus
● Postural deformity
● Medial longitudinal arch of foot is collapse/flattened
● The whole foot/part of the sole touches the ground
while standing
● The heel in this deformity goes into valgus with
prominence of talus medially.
● In this deformity, there is bulging on the medial
aspect of the foot, which is due to displacement
of the head of the talus medially from the
navicular.
● Loss of medial longitudinal arch due to ligaments and muscles
● Arches-
❖ Wedge-shaped blocks
❖ It supported and formed by complex network of Ligaments, Muscles, Bones
❖ and tendons
● Function
❖ Weight bearing spring to absorb shock
❖ Distributed the body weight
❖ Act as lever to propel body forward in walking , running, jumping
● Epidemiology
❖ More prevalent in children.
❖ Female > Male

Types of Arches
Types of flat foot
1. Rigid/True/Congenital
Flat Foot:
2. Supply/ Flexible/
Pediatrics flat foot
Arch absent in sitting and
standing
Arch present in sitting and tiptoe
standing
Arch never appears Arch disappears only during
weight-bearing
Often painful and pathological Usually painless and
physiological
Less common Common in children
May lead to arthritis Usually resolves as the child
grows
1. Genetics
2. Ligament laxity in congenital diseases such as
Marfan syndrome.
3. Charcot's arthropathy.
4. Obesity.
5. Pregnancy.
6. Tight Achilles tendon
7. Under medical condition
❏ Tarsal condition (restriction in movement)
❏ Osteoporosis
❏ Congenital anomalies
Common causes
Pathophysiology
1.Normal Medial Longitudinal Arch
2. Soft tissues
1. NORMAL FOOT
2.WEAKNESS/INJURY/
LIGAMENT
LAXITY/TENDON
DYSFUNCTION
3. LOSS OF ARCH
SUPPORT
4. COLLAPSE OF
MEDIAL ARCH
5. FLAT FOOT (PES
PLANUS)
NOTE:Dysfunction/Injury to any of the supporting leads to collapse of the medial longitudinal arch, Result: Flat foot deformity
Diagnosis
X-ray-foot shows C-sign , developing from a bony bridge
Clinical features
1. Lowering of the Dome on the medial side of the foot 2. Inward Turned Ankle (Hindfoot Valgus)
4. Ankle and Foot pain
3. Weight Bearing on the Medial aspect of the foot
5. Tip toes Walking/Running

PHYSIOTHERAPY
1.Strengthening exercises:Tibialis posterior tibialis anterior, flexor hallucis longus,
flexor digitorum longus, intrinsic foot muscles, abductor hallucis muscles are given
either manually, or using weight cuff/theraband.
2. Stretching: Gastrocnemius-soleus complex, stretching of peronei (most particularly
peroneus brevis muscle),
3. Passive ROM exercise
4. Foot Pain Management
Faradic
foot bath
cryotherapy/
contract bath
Ultrasound
★ Orthotic management—Shoe modification:
1. Thomas heel
● Medial heel and sole raise with medial arch support.
● wedge with extended anterior medial border
2. Silicon arch support/Scaphoid pads
3. Supramalleolar orthosis(SMO)
● It supports foot just above the ankle bone ot malleolus.
Surgery:
❖ Tendon transfers
❖ Osteotomies
❖ Arthrodesis (triple arthrodesis)
Complications:
● painful arthritis.
