25
What movements are involved in superficial posterior
- plantarflexion - flexion (knee) - gastrocnemius
26
What muscles are involved in deep posterior
- flexor digitorum longus - flexor hallucis longus - tibialis posterior (popliteus)
27
What movements are involved in deep posterior
- plantarflexion - inversion - flexion (toes)
28
What muscles are involved in anterior
- tibialis anterior - extensor hallucis longus - extensor digitorum longus - peroneus tertium
29
What movements are involved in anterior
- dorsiflexion - inversion - eversion - extension (toes)
30
What muscles are involved in lateral
- peroneus longus (long) - peroneus brevis (short)
31
What movements are involved in lateral
- plantarflexion - eversion
32
What is the lateral origin of the gastrocnemius?
posterior of lateral femoral condyle
33
What is the medial origin of the gastrocnemius?
posterior of medial femoral condyle
34
What is the insertion of the gastrocnemius?
posterior surface of calcaneus (via achilles tendon)
35
What is the innervation of the gastrocnemius?
tibial nerve
36
What is the palpation of the gastrocnemius?
upper half of posterior lower leg
37
What is the origin of the soleus?
posterior of proximal fibula and proximal 2/3 of posterior tibia
38
What is the insertion of the soleus?
posterior of calcaneus (via achilles tendon)
39
What is the innervation of the soleus?
tibial nerve
40
What is the palpation of the soleus?
under gastrocnemius
41
What is the origin of the tibialis anterior?
upper 2/3 of lateral surface of tibia
42
What is the insertion of the tibialis anterior?
inner surface of medial cuneiform and base of 1st metatarsal
43
What is the most common foot/ankle injury?
ligament sprain (inversion)
44
List the plantarflexors in the foot/ankle
- gastrocnemius - soleus - tibialis posterior - FDL - FHL - peroneus longus - peroneus brevis
45
List the dorsiflexors in the foot/ankle
- tibialis anterior - EDL - EHL - peroneus tertius
46
List the invertors in the ankle/foot
- tibialis anterior - tibialis posterior - FDL - FHL
47
List the evertors in the ankle/foot
- peroneus brevis - peroneus longus - peroneus tertius - EDL
48
What is a ligament sprain (inversion)?
- ankle ligament tear - usually 2+ together - anterior talofibular and calcaneofibular most common pairing
49
What is the mechanism of a ligament sprain (inversion)?
- inversion and supination - usually on landing or incorrect/uncoordinated placement of the foot
50
What is the management of a ligament sprain (inversion)?
- RICE - NSAIDs - progressive rehabilitation
51
What is the presentation of a ligament sprain (inversion)?
- specific pain when joint is loaded/moved - tenderness and swelling to anterior and lateral regions - bruising behind and below lateral malleolus
52
What is the complications of a ligament sprain (inversion)?
- reinjury - reduced performance
53
What is tibial stress syndrome commonly known as?
shin splints
54
What is the mechanism of tibial stress syndrome?
- usually caused by overuse - periostitis - acute inflammation of tendon sheath
55
What is the management for tibial stress syndrome?
- RICE - NSAIDs - progressive rehabilitation - surface change
56
What is the presentation of tibial stress syndrome?
- local pain with plantarflexion (medial tibial) or dorsiflexion (anterior tibial) - tenderness, heat and inflammation
57
What is the complications for tibial stress syndrome?
- reinjury - reduced performance - could be masking a stress fracture of the tibia
