ANKLE 3 Primary Joints Medial malleolus w/average bone Tibial plafond w/talar arch Lat malleolus w/lat bone 3 Bones: Tibia, Fibula and Talus 3 sets of Ligaments: Lateral pledges (ATFL, CFL, PTFL) Syndesmotic Ligaments Medial guarantees (Deltoid) ANATOMY 101

Slide 11

What are steady cracks? Lower leg shapes a ring Disruption of just 1 structure is steady Disruption of > 1 is unsteady

Slide 12

Approach to Ankle/Foot X-beams Go through total approach (ABC's) 3 sees AP, lat, Mortise (15-20 ° int spoil) lower leg, Direct proof of damage: survey bones Indirect confirmation of wounds: are all lower leg estimations ordinary? Joint emission? Depict x-beam, as opposed to just naming it

Slide 13

Management all in all Chip/separation #'s <3mm = Tx as sprain Non-dislodged, non-intra-articular, stable #'s 3 wks NWB thrown, 3-5 wks WB thrown, f/u with cast center Unstable #'s, intra-articular # - talk with Ortho Open – saline splashed dsg, IV ABx, Td, Ortho desperately NV trade off – lessen and call Ortho Urgently

Slide 14

Diagnosis?Classification?Treatment? Does it transform you mgmt in the event that they have a delicate deltoid tendon?

Slide 15

Lateral Malleoli #'s MC lower leg #, MOI: usu reversal harm Weber order – used to decide danger of syndesmosis damage and in this way requirement for agent repair Management NWB x 3wks, WB x 3-5wks* Refer B's or C's, Functional bimalleolar's to ortho

Slide 16

Stable ? Is the area critical? Administration? What estimations/lines do you take a gander at in the lower leg? What do they connote?

Slide 18

Syndesmosis harm 1 >10 mm B A Medial clear Space <5mm 2 3 4 A-B = talar tilt <3 is typical

Slide 19

Point out 3 variations from the norm. Analysis? Stable? Treatment?

Slide 20

Maisonneuve

Slide 21

Diagnosis? Treatment?

Slide 22

Bimalleolar/Trimalleolar #'s Involve the average, parallel or potentially back malleoli Splint, torment control, NPO Need to address ortho as they will probably require OR

Slide 23

Mechanism of harm? Related wounds? Administration?

Slide 24

PILON # Mechanism of damage pivotal load? Related wounds calcaneus, C,T & L spine, pelvis, intra-stomach. Administration OR, approx half are open cracks

Slide 25

Description? What would you like to know/evaluate? What would you like to do? How?

Slide 26

Ankle Dislocations Relatively normal, as a rule assoc w/# Describe the position of foot/bone to tibia If open, Tx accordingly X-beams ought not defer diminishment if NV bargain or skin rising present Analgesia/PS, Reduce, support, post-red movies

Slide 27

Pediatric Ankle Injuries Not simply minimal grown-up # The tendon connections are more grounded than the physis in this way more #'s, less sprains Overall administration is like grown-ups Although with breaks you can acknowledge more angulation (next to zero dislodging) LLC throws are the underlying decision for most #'s

Slide 29

Can we apply OAR/OFR in youngsters? Six reviews took a gander at approving OAR in peds Different age bunches (2-18, 6-16) Sens 85*-100*% Considered all # Some viewed as all #, others just "huge #")

Slide 30

BMJ 2003. Precision of OAR to prohibit breaks of the lower leg and mid-foot: A deliberate audit This review references the majority of the OAR done in kids and additionally grown-ups

Slide 31

Problems with the reviews Haven't thought of a typical meaning of critical # Unsure of what to do with SH-1, conflicting Dx Local practice (and Edmonton) – variable some apply it, some utilization lead + attentiveness, others utilize clinical judgment

Slide 32

Conclusion This should be further considered Need to figure out which #'s are huge But I think they will probably be approved Although I think they'll need to Tx SH1 as particular wounds

Slide 33

Describe crack? Arrangement? Administration? SH-2 LLC x 3 wks, then SLC X 1-3 wks

Slide 34

Describe break? Order? Administration? SH2 Reduction/immbolize (air cast)

Slide 35

SALTR L ower (epiphysis) R am (Crush) S traight T hru the Physis A bove (metaphysis)

Slide 36

Non-agent administration for SH 1-2 Attempt shut lessening, can acknowledge more angulation Long leg cast x 3wks, trailed by SLC x 3wks SH 3-4 - > OR SH 5 - >poor fx visualization Complications for SH 3-5 incorporate development capture, appendage length inconsistency

Slide 37

Acute Skin corruption NV harm Compartment disorder # Blisters Wound contamination/osteo Chronic Mal-union Non-union Post-traumatic joint inflammation AVN Chronic agony Chronic unsteadiness Ankle # Complications

Slide 38

Describe # Do you have to address Ortho? ?ottawa lower leg rules Talar Dome # Yes – Ortho to find in cast center

Slide 39

Describe # Anything unique about this bone? Blood stream distal to proximal like scaphoid and proximal femur, thusly inc AVN hazard Is there an order framework for these #'s?

Slide 40

Talus Neck Body Head Chopart's joint

Slide 41

Talar breaks Minor talar cracks Chip and separation breaks of neck ,head, and body. Generally same system as lower leg sprains Talar neck breaks half of major talar wounds. outrageous dorsiflexion compel Hawkins arrangement Talar body breaks 23% of all talar cracks (counting minor cracks) Major talar body cracks are unprecedented normally pivotal stacking (e.g. falls) Talar head cracks Uncommon (5-10%) compressive constrain transmitted up through the talonavicular joint connected on a plantarflexed foot

Slide 42

Hawkins Classification of Talar Neck Fractures Type 1: = nondisplaced; Type 2: subtalar subluxation Type 3: disengagement of the talar body (half open #'s) Type 4: separation of the talar body & diversion of the talonavicular joint. Break sort impacts administration & visualization Thanks Moby

Slide 43

Describe harm. Name this injury.v Management?

Slide 44

Describe harm. Name this damage Lisfranc Management? On the other hand

Slide 46

What to search for on x-beam: Normally, average part of metatarsals 1-3 ought to adjust to average fringes of cuneiforms Metatarsals ought to be adjusted dorsally to tarsals on horizontal view Medial 4 th metatarsal ought to adjust to average cuboid Any crack or separation of the navicular or cuneiforms or augmenting between metatarsals 1-3 Proximal 2 nd metatarsal # is patho gnomonic Thanks Dave

Slide 47

Normal Lisfranc joint arrangement Tx: Need to address ortho May attempt shut decrease

Slide 48

Describe. Administration NWB cast # usu from direct injury

Slide 49

Describe. Administration Walking cast x 2-3 weeks Avulsion sort #

Slide 50

Metatarsal # Treatment: Nondisplaced or min uprooted breaks of metatarsal 2-4 stiff shoe, throwing, or crack support. Non uprooted 1 st metatarsal  NWB BK strolling cast (cuz it's a noteworthy WB surface) Displaced 1 st or 5 th metatarsal  ER ortho Attempt shut lessening if >3mm relocation or 10 degrees angulation Thanks Dave

Slide 51

Phalangeal #'s Non-dislodged: amigo tape, (air give if hallux included a role as they are difficult) Significant removal/angulation: shut diminishment - > talk with ortho if decrease is insufficient (esp w/hallux) If subungal hematoma is available with tuft # - clear hematoma and repair nail bed

Slide 53

Posterior tuberosity pinnacle of front process summit of back feature

Slide 55

Calcaneus # Management Order Harris (hub view), may require CT Probably ought to address Ortho for all since x-beams under-gauge degree of harm But… non-dislodged, additional articular – NWB cast x 6-8 wks Otherwise, Tx changes extensively and is best dictated by Ortho

Slide 56

Summary Ankle #'s If #/damage disturbs>1 structure in ring = temperamental or if intra-articular – ortho Otherwise: NWB cast x 3wks Foot Stable, additional articular, wgt bearing surface NWB cast Unstable, or intra-articular – ORTHO Stable, additional articular, non-wgt bearing surface: moderate mgmt (inflexible shoe, strolling cast, pal tape) If in uncertainty, Look up administration of # - excessively numerous particularities to remember
