4 compartments of the leg
-function -approach to decompress? - contents of this compartment (ACheaven) |
anterior compartment,
- dorsiflexion of foot and ankle anterolateral incision- identify and protect the superficial peroneal nerve, fasciotomy of anterior compartment performed 1cm in front of intermuscular septum 1 tibialis anterior 2 extensor hallucis longus 3 extensor digitorum longus 4 peroneus tertius 5 deepr pereonal nerve 6 anterior tibial artry & vein |

4 compartments of the leg
-function -approach to decompress? - contents of this compartment (SPC/beer) |
superficial posterior compartment
function-mainly plantarflexion of foot and ankle posteromedial incision-protect saphenous vein and nerve incise superficial posterior compartment 1gastrocnemius 2soleus 3plantaris 4 medial suralcutanious nerve (sciatic n) 5 poplteal artery & vein |

4 compartments of the leg & -function
-approach to decompress? - contents of this compartment ()LC/traffic light) - isolated lateral compartment syndrome PE findings ? |
lateral compartment
function-plantarflexion and eversion of foot anterolateral incision, identify and protect the superficial peroneal nerve fasciotomy of lateral compartment performed 1cm behind intermuscular septum 1 peroneus longus 2 peroneus brevis 3 superficial peroneal nerve -superficial peroneal nerve Decreased sensation dorsum of his foot i hallux, 3rd, and 4th toes |
|
4 compartments of the leg & -function
-What ankle position lowest deep posterior calf compartment pressures in leg -approach to decompress? -name the muscles in each -compartment (DP/beer) |
-deep posterior compartment
function- plantarflexion and inversion of foot muscles Neutral to 30 degrees of plantar flexion posteromedial incision protect saphenous vein and nerve detach soleal bridge from back of tibia to adequately decompress deep posterior compartment 1tibialis posterior 2 flexor digitorum longus 3 flexor hallucis longus 4 tibial nerve 5 posterrior tibisl artery & vein |
|
-single lateral incision describe
-which structures is at risk during proximal dissection of a single lateral perifibular approach? (elevator) |
-single lateral incision from head of fibula to ankle along line of fibula by following interosseous membrane from the posterior aspect of fibula and releasing compartment from this membrane
-Common peroneal nerve at risk with proximal dissection |
|
compartment syndrome
-sx, 1st sx -PE & most sensitive clinical sign in child? --indications emergent fasciotomy? (traffic light) -best predictor for compartment of syndrome in pediatric pt |
sx-pain out of proportion to injury
PE-pain w/ passive stretch, iintact MENTAL STATUS - child, increasing analgesia requirement is more sensitive -1 unequivocally positive clinical findings -->emergent surgery without need for compartment measurements 2 compartment pressures with absolute value of 30-45 mm Hg 3 compartment pressures within 30 mm Hg of diastolic blood pressure (delta p) - child, increasing analgesia requirement is more sensitive not mech inj |

3 What do you see?
1 diagnostic study of choice? (DSC) 2 (RXrV &PPFs?) Recommended X-ray Views looking & PathoPnemonic Findings -hx-epid-doing/associations, MoI, symptoms -5a/b what is the treatment? A (conservative treatment is B surgical indications (PE/image findings/time) 6 what are risks with treatment/non treatment? (complications) |
Die-punch fxs
A depressed fracture of the lunate fossa of the articular surface of the distal radius, volar shearing fracture with comminution creates a functional radiolunate ligament avulsion, which can lead to instability; volar aspect of the lunate fossa bears more load than the scaphoid fossa and be difficult tro treat |

Origin
Insertion Action Arterial Supply |
Origin-Lateral condyle of tibia, proximal 1/2 - 2/3 or lateral surface of tibial shaft, interosseous membrane, and the deep surface of the fascia cruris
Insertion-Medial and plantar surfaces of 1st cuneiform and on base of first metatarsal Action Dorsiflexor of ankle and invertor of foot Innervation Deep peroneal nerve (L4, L5) Arterial Supply Anterior tibial artery |
