Basic steps of Hip Arthroscopy
- Position & Mark Landmarks
- Apply traction
- Central Compartment
- Release traction
- Peripheral Compartment
Patient Positioner features (x4)
- Active Heel Technology (Conforms to patient, secure)
- Military Grade buckles & straps (Easy to secure & release)
- Fits both left & right feet (No double checking correct boots)
- Quick disconnect (Quick, Easy, can load foot into boot prior to positioning)
Hip Portals - marking
Find ASIS, mark midline down leg (suicide line)
1. ALP - Find & palpate GT, portal = 2cm Superior and Anterior to GT.
2. AP - Follow ALP towards suicide line, go back 2 cm
3. PLP - 2cm Superior and Lateral to GT
4. Mid Anterior Portal - 45 degree from ALP to suicide line. Anywhere within triangle.
Hip Positioner Technique
- Attach using 4 clamps
- Blue cushion - Perineal post hole on op leg side
3 Attach well leg & distractor leg - Attach Traction boots (Active Heel on OP leg) & white clip to lock
- Patient boots on
- Patient into traction boots
- Perineal post and pad, and smooth down
- Gentle traction on well leg
- Loosen orange knob & ball joint and pull for gross traction
- Fine traction & xray. (2hrs max in traction)
Steps using Crosstrac
Traction, mark skin
1. 17 gauge spinal needle in ALP. Xray/needle/xray/needle
2. 40cc saline into joint
3. Guidewire down needle, remove needle
4. Scalpel, Insert 4.5mm (G) Arthrogarde Cannula plus Delrin Handle Obt over guidewire
5. Remove Obt and guidewire
6. Attach scope and irrigation extender
7. Attach Crosstrac
8. Black top obt into Crosstrac to AP mark
9. Push to skin, incision, insert, XL needle, guidewire
10. Remove all aprt from guidewire
11. Put in switching stick & Viktor OR 2 nd Arthrogarde
