The Foot (Bones) Bones = 26 14 phalanges 5 metatarsals 7 tarsals
Toes (Phalanges) Designed to give wider base for balance and propelling the body forward. 1st toe (Hallux) Two sesamoid bones located under the 1 st MP joint.
Metatarsals 5 Bones 1 st metatarsal is the largest and strongest and functions as the main body support during walking and running. Palpable at the ball of the foot. 5 th metatarsal most common fractured.
Tarsals 7 bones Aids in the support of the body. Calcaneous = largest tarsal bone, supports talus and shapes heel, and provides attachment for achilles tendon.
Joints of the Foot Interphalangeal joint (IP) Flexion / Extension Metarsalphalangeal joint (MP) Flexion / Extension Abduction / Adduction
Bones of the Ankle Tibia Main weight bearing bone of LOWER LEG Forms medial malleolus Fibula Non-weight bearing Mainly muscle and ligament attachment Forms lateral malleolus Talus Main weight bearing bone of the ANKLE

Foot and Ankle Injuries
Ankle Sprain Cause: Excessive inversion or eversion of the ankle S/S: Point tenderness, swelling, discoloration, laxity, inability to walk or run properly (extent based on degree). TX: RICE, rehabilitation immediately (Grade III requires immobilization) Prevention: Strengthening exercises, proper shoes/ equipment
1 st Degree Ankle Sprain Mechanism (MX) Inversion and/or plantarflexion ATF most common sprained Occurs during contact or non contact.
S/S 1 st degree Mild pain Pt ATF Possible swelling Fast recovery to FWB and ROM No joint laxity
2 nd Degree Ankle Sprain MX Same as 1 st degree, more severe. Involves the ATF, CF Possible growth plate involvement Most cases x-ray needed
S/S 2 nd degree Felt a pop Localized severe pain Pt more then one ligament Rapid swelling Decrease ROM Laxity in joint Unable to FWB
3 rd Degree Ankle Sprain Rupture of ligaments (ATF, CF, PTF) Consider a FX X-ray is mandatory
S/S 3 rd Degree Felt or heard pop Extreme pain Extreme/rapid swelling No ROM Unable to FWB
1 st Degree Ankle Sprain RICE Return to Play (Toe raise, heel walk, Full go w/ full ROM Tape to Play Reevaluate 24hrs 2 nd Degree Ankle Sprain RICE (Horseshoe w/ compression wrap) Crutches 24 hours Reevaluate 24hrs Refer to Dr. X-rays 3 rd Degree Ankle Sprain RICE (Horseshoe w/ compression wrap) Crutches Walking Boot Refer to Dr. X-rays
Syndesmotic Injury High Ankle Sprain of ligaments between tibia and fibula Associated with rotational injury Pushed back on planted foot Interosseus Ligament Anterior-Inferior Tibiofibular Ligament Posterior-Inferior Tibiofibular Ligament
Physical Exam: Syndesmotic Injury Pain with External Rotation Test Separates tibia from fibula Tenderness between tibia and fibula Positive Squeeze test Limited dorsiflexion Pain with weight bearing and rising up on their toes Imaging: X-Ray Possible widening of the space between tibia and fibula
Treatment of High Ankle Sprain Boot as needed if severe pain Functional Rehab Strengthening, early ROM Similar to ankle sprain Takes twice as long to recover as compared to ankle sprain Widening with fracture may require Ortho referral for surgical repair
Anterior Drawer Test Tests for ligament instability Mainly tests ATF integrity but can also test the CF and PTF depending on severity Ankle must be relaxed Ankle in slight plantar flexion
Talar Tilt Test for lateral ankle instability Positive test indicates tear in ATF, and CF Kleigers Test Test for High Ankle Sprain. Dorsiflexion and external rotation
Squeeze Test Compression of the mid tibia and fibula with reproduction of pain in the ankle Indicates High Ankle Sprain pain from syndesmotic injury http://step.nl/enkelverzwikking-enkeldistorsie-inversietrauma-enkelbrace-proprioceps
Ankle Dislocation Mx: Heel strikes ground forcefully; blow to anterior lower leg S/S: Deformity, inability to move foot, rapid swelling, refusal to allow moving or touching foot TX: Splint, ICE, 911 or transport to hospital https://www.youtube.com/watch?v=3mlxrmfj HJUl
Turf Toe Sprain of the 1 st MP joint Mx: S/S Hyperextension/ hyperflexion of great toe Common on artificial surface Flexible types of footwear can contribute Pain over the first MP joint
Achilles Tendonitis MX: Repetitive motions such as running and jumping that cause tendon breakdown S/S: Swelling, crepitus, pn with palpation, pn with dorsiflexion, weak with plantarflexion TX: RICE Limiting or restricting the activity that caused the irritation Aggressive stretching of heel cord Crepitus (crackling and grinding) may mean it is too late Prevention: Achilles and gastroc/solues stretching, proper acclimization to activity.
Achilles Tendon Rupture MX: Sudden, forceful dorsiflexion of the ankle with a chronically tight tendon. S/S: Feel or hear a pop. Feel as if they ve been kicked in the leg. Inability to plantar flex foot. TX: Surgery or a cast Prevention: Stretching and proper care of any tendonitis https://www.youtube.com/watch?v=fbskdt0xklw
Thompson Test Test for achilles tendon rupture
Longitudinal Arch Strain Mx Downward force to the foot causing depression of the arch Most common with overuse (running) S/S Sharp pain with weight bearing Painful during dorsiflexion
Lower Leg Problems Shin Splints : catch all term related to lower leg pain. MX: constant pounding associated with running S/S: sharp pain in lower leg around medial/lateral aspect of lower leg and connective tissue between tibia and fibula TX: RICE (cold whirlpool), heal lift, arch support, shoes, change running surface
MX: Compartment Syndrome Increased pressure within one of four compartments of lower leg causes compression of the structures in the leg. S/S: Deep aching pain, tightness, and swelling. Pain with stretching. TX: Acute~ immediate surgery Chronic~ activity modification & ice and some times surgery Prevention: Stretching (Hard to prevent)

Lisfranc Injury Lisfranc Ligament: Base of 2 nd Metatarsal Medial Cuneiform -Injury causes separation of the base of the 1 st and 2 nd metatarsals leading to forefoot instability
Lisfranc Injury Injury is referred to as a Lisfranc if there is any disruption of the tarsometatarsal joint complex Injury can range from sprain of the Lisfranc ligament to dislocation (due to ligament tear) to fracture Why is this area of the foot prone to injury? Transverse ligaments connect the bases of the four lateral metatarsals No transverse ligament exists between the 1 st and 2 nd metatarsal bases Minimal support = increased risk of injury
Imaging X-Ray Weight-bearing: AP and lateral, +/- oblique -Tell radiology what diagnosis you are concerned about Lisfranc Injury XR Evaluation: Look for widening of space between 1 st and 2 nd metatarsal Look for fracture at base of 2 nd metatarsal XR findings very subtle. If have midfoot pain and negative XR, still possibly a Lisfranc and needs follow up http://orthoinfo.aaos.org/topic.cfm?topic=a00162
Toe Abnormalities Hammer Toes MX: TX: Poor shoe choices Middle joint (PIP) flexed, other joints (MP, DIP) hyperextended Refer, orthotics or surgery
Bunion / Hallux Valgus MX: Bony enlargement of the head of the 1st metatarsal caused from wearing improperly fitting shoes S/S: Obvious deformity, tenderness, and swelling TX: Proper shoe selection, protection devices, surgery may be necessary Prevention: Properly fitting shoes
MX: Ingrown Toenail Improper shoe fitting and nail cutting S/S: Increased pain, swelling, redness around the nail bed TX: Hot, soapy water, antibiotics, raise nail up Prevention: Proper shoes, proper nail trimming
Foot & Ankle Rehab Begin rehab with modalities. E-Stim, Thermotherapy, Massage, Etc. **Remember the 3 components that need to be done sequentially** 1) Flexibility and ROM 2) Strength and Muscle Endurance 3) Proprioception, Coordination, and Agility
