KIN 361 – Lecture 7 Notes
Achilles Tendonitis
- Achilles tendon: the band of tissue connecting muscles of the calf to the heel
bone
- injury most commonly found in runner
who have suddenly increased the
intensity/duration of their runs
- recovery time may last for 4-6wks
● Mechanism:
o Traction forces on the tendon
• Cause
o Excessive pronation
o Uphill running
o Cavus foot
• Treatment (Tx)
o Bilateral heel lifts
o Rx, S&S
Achilles Tendon Rupture
● Mechanism:
o Eccentric contraction
• Cause
o Landing from dismount
• Treatment (Tx)
o Surgery
Fractures – styloid avulsion
- The styloid is forcibly detached from its normal point
● Mechanism:
o Eccentric contraction of peroneals
• Cause
o Plantarflexion + inversion
• Treatment (Tx)
o Surgery
Fractures – metatarsal
● Mechanism:
o Axial load
o Transverse load
• Cause
o Kicking something
o Getting stepped on
• Treatment (Tx)
o O.R.I.F. – Open Reduction Internal
Fixation (Surgery procedure)
Fractures – Malleolar
● Mechanism:
Document Summary
Achilles tendon: the band of tissue connecting muscles of the calf to the heel bone injury most commonly found in runner who have suddenly increased the intensity/duration of their runs recovery time may last for 4-6wks. Mechanism: traction forces on the tendon, cause, excessive pronation, uphill running, cavus foot, treatment (tx, bilateral heel lifts, rx, s&s. Mechanism: eccentric contraction, cause, landing from dismount, treatment (tx, surgery. The styloid is forcibly detached from its normal point. Mechanism: eccentric contraction of peroneals, cause, plantarflexion + inversion, treatment (tx, surgery. Mechanism: axial load, transverse load, cause, treatment (tx, kicking something, getting stepped on, o. r. i. f. Internal: avulsion, compression, cause, extreme inversion, extreme eversion, treatment (tx, surgery. Fractures maisonneuve spiral fracture of the proximal third of the fibula caused by a tear in the distal tibiofibular syndesmosis and the interosseous membrane. Mechanism: transverse compression of fibula, cause, sliding tackle, kick, extreme inversion, treatment (tx, surgery, if displaced.
