BONES Flashcards
The pin should just take __% of the bone
70-80%
at the start of the surgery, the pin should be longer than the bone
true
you can prepare just 1 size
false
incision approach
craniolateral border
tool for reduction
bone holding forceps
tool used to reduce space between bones
bone holding forceps
key to bone surgery
proper visualization
steps in bone suegry
- reduction
- apposition
- preliminary fixation
used to hold bones togetehr
cerclage wires
differentiate normograde vs retrograde
- going distal
- going proximal, then into and towards the distal end of bone
angle of pin insertion
20
pin insertion should be aligned with the ______ of the bone
medullary axis
drive the pin into the ___ of distal metaphysis
cancellous bone
when penetrated may cause inflammation
cortex
aftercare phase 1
resolve inflamm, edema and pain
aftercare phase 2
Resolve hematoma/edema
Prevent muscle contracture
how long do bone healing lasts
6 or 8-12
indication for FHO
hip dysplasia, fractures esp. recurrent
tools needed for FHNO
major surgical pack
bone hammer
chisel (osteotome)
bone saw/cutter
bone rasp/file
incision approach for FHNO
craniolateral to thigh
cranial to greater trochanter
where to cut in FHNO
neck
how many people to do FHO
at least 3
what are checked after FH is freed
bony prominences
irregularities
range of motion [grinding, bony contact]
suture pattern on deep gluteal
mattress
suture pattern on muscle reattachment
simpl. int.
suture material for closing of joint capsule over acetabulum
o - 2-0
popular rehab
swimming
supplements are for life
true
Healing is generally complete after 4 weeks
6 weeks
primary fixation, external fixation
cast or splint - external coaptation
primary fixation , internal fixation
IM pins and/or k wires
ESF
ILN
BPaS
ancillary fixation, internal fixation,
lag screws
full cerclage
hemi cerclage
indications for IM pin + cerclage wire
long oblique fractures, spiral fractures of feumir, tibia and humerus
indications for ILN
comminuted fractures, limited bone length, very rigid repairs
ESF indication
open contaminated fractures, avulsion, concern to implants causing infection, osteomyelitis or explantation
BPS indication
Any fracture in which there is enough bone length proximal and distal to the fracture to allow placement of 3 screws in each fragment, engaging a minimum of 6 cortices
aftercare for FHNO
1-14 days anti inflamm, edema, pain
rehab early
first muscle seen after first incision
biceps muscle
second muscle seen after biceps muscle
vastus lateralis on left
adductor magnus muscle on right and under
FNO or FHNO meaning
FHO (FHNO) FEMORAL HEAD (AND NECK) OSTECTOMY
when can sutures be removed after pin placement
10-14 days
