Shin splints
Periostitis vs tendonitis
Overuse & biomechanical factors
Muscle imbalance
• Tx based upon accurate dx

• Modalities, stretching to posterior muscles and strengthening anterior
stress fracture
Usually metatarsals or tibia
Sometimes difficult to differentiate from shin splints
Dx: x-ray, repeat x-ray, bone scan
exertional compartment syndrome
Exercise induced pain in lower leg at specific compartments
Cramping, burning, tightness, aching
Growing evidence for conservative tx vs surgery
Diff diagnosis: periostitis, stress fx, vascular/neural entrapment
ACUTE COMPARTMENT SYNDROMES ARE A MEDICAL EMERGENCY

Eccentric strengthening, address impairments and biomechanical factors
plantar fascitis
o AM pain, limited gait mechanics, pain provoked with palpation and DF of great toe
o Stretching very effective with soft orthotic and night splint
95% recover with conservative tx - can take up to a year
surgery = last resort, high complication rate...wait 12-18 mos
o Associated factors: obesity, pes planus, pronation, cavus feet, tight gastroc

Accommodative orthotic: soft with MT pad or cutout
calcaneal
o Extra or intraarticular
o Fx of the body are the result of a large compressive force
o Conservative vs surgical based on factors such as configuration, displacement, soft tissue involvement
o NWB during initial phase
o Lose significant STJ ROM - may lead to STJ fusion
talus
o Mostly intraarticular due to large amt of cartilage
o Osteochondral lesions as a result of forces with fx or sprains
forefoot
o Nondisplaced 2-5: tape and WBAT
o Nondisplaced 1: NWB x 2 weeks
o Displaced: must be accurately reduced
o Nondisplaced 5: jones fx = base of 5th met and avulsion fx of tuberosity - can extend into proximal diaphysis - high incidence of nonunion
phalanges
o Tape immobilization and protected WB
ankle
o Classification: lateral, medial, bimalleolar, trimalleolar
Lateral: surgery with static or dynamic incongruency only - all others have good results with closed reduction
Bimalleolar: usually require ORIF
Trimalleolar: involvement of the posterior lip of the tibial plafond - usually require ORIF
All require 4-6 of NWB
Rehab problems: limited CKC DF, weakness, gait deficits
