Hip luxation Flashcards
Schlag JAVMA 2019
Retrospective multicenter
Closed reudction Ehmer sling 92 dogs craniodorsal hip lux
40% reluxated
Reluxation 5x higher risk if initial injury was due to trauma
50% soft tissue injury a/w sling
Ehmer low success high comp
Le Floch JFMS 2022
Retrospective 51 cats hip lux closed reduction
50% success
Loh VS 2024
Nonsurgical management of caudoventral hip luxation 170 limbs
Ehmer sling not recommended (20%)
Hobbles 60% success, Toggle 88% success
closed reduction alone 10%
low trauma etiology and poodle crosses were overrepresented
Trostel JAAHA 2020
Retrospective 58 dogs
Toggle rod with orthofibre, fibrewire, nylon
20% major comp - 10% relux (majority were nylon)
90% owner satisfaction
Darrow VCOT 2021
19 cadaveric hips - accuracy of PSDG for toggle via minimally invasive sx
80% ideal placement
Not that accurate for femoral or acetabular bone tunnels
-errors in identifying borders of fovea capitis on CT data
Matthews VS 2021
Retrospective 128 dogs
Risk factors reluxation after toggle stabilisation
25% postop comp - 15% relux
non traumatic, low impact lux higher risk for relux
Traumatic lowest risk for relux
Rivenburg VCOT 2022
Cadaveric study
arthroscopic assisted toggle via limited arthrotomy
Bone tunnels all within acetabular fossa - high accuracy
accuracy of femoral tunnels not as highu
Ruperez VS 2021
Retrospective 48 CATS
Toggle with UHMWP or nylon
25% postop comp - 10% relux
97% outcome good-excellent
no diff in UHMWP and nylon
Cats that underwent other ortho procedures higher relux risk
Ruperez VS 2023
Ex vivo arthroscopic hip toggle in cats
5/7 intraop comp relating to bone tunnel and toggle dislodgement
femoral tunnel hardest
no articular damage
Knell VCOT 2023
Retrospective study
Mini tightrope 32 cats hip lux
8% double strand vs 25% single strand failed - double stranded implant recommended
50% developed moderate OA - OA is common after open reductions
Redolfi JAAHA 2023
Retrospective study
prosthetic capsule replacement 15 dogs with traumatic hip lux
acetabular screws and washers Ethibond (polybutane coated polyester prosthetic lig)
13% major comp (1 relux, 1 capital physeal #)
91% overall success
Letesson JFMS 2022
Ex vivo cadaveric cat craniodorsal lux model
extra articular UHMWP (NovaLig) with interference screw VS iliofemoral suture UHMWP
recurrence higher with iliofemoral suture
