Assistant everts wall
Pinch stomach wall to separate submucosa and mucosa and tunnel under with haemostat and cut over the top - 34When is the best time to preform an OVE?Before second season or coming into heat (5-6 months)
- 35What is the difference between dogs and cats for OVE incision?Dogs - cranial extent of umbilicus scar
Cats - between umbilicus and pubis - 36What is a flank spay CI for?Point cats as fur may grow back a different colour
- 37What animal has a long term risk of EAN?Bitches - urinary incontinence
- 38Which animals should you break vs stretch ligament in for OVE?Cat - stretch
Dog - break - 39What type of ligature is used on the ovarian pedicle?Circumferential
- 40What does IM pins and cerclage prevent?IM pins stop bending
Cerclage wire stops shearing and rotation - 41What is a reconstructable fracture?Anatomical reconstructed
Primary bone healing
Load sharing with implants - 42What is a non reconstructible fracture?Cannot put them back together to make load sharing so implant takes all weight
Biological repair
Leave fracture and blood supply intact - 43When can you use an IM pin without cerclage?Interlocking simple fractures in young patients
Transverse fracture - 44When is cerclage CI?Young animals as may cause ring bark bone
- 45What bone should you never put an IM ipn in?Femur, tibia and humerus
- 46What should you ensure your pin in in ?Medullary bone from either end
- 47When is IM CI?Communited fractures, open fractures, wide bones
Never as sole means of fixation for transverse - 48What bones do you approach normograde for IM?Femur to avoid hip joint and sciatic nerve
Tibia to avoid stifle joint - 49What is dowel pinning?IM pin that has no access points (all internal)
- 50When do you use dowel pinning?Paired bones as stability is from multiple pins and splint
Metacarpal bones as no way of pinning without damaging joint - 51What is the benefit of a Jacobs Chuck over a electric drill?Complete sterility
- 52How do you not hold a Jacobs Chuck?Back end in the palm (pin may go through)

- 56What is interfragmentary cerclage?Small IM pins have cerclage wire looped around external part
- 57What is tension banding?Compression using two wires in the bone in a figure of 8
- 58What are the problems of cerclage?Loose loops damage blood supply
Prevent bone growth in young animals - 59What may cause implant failure?Incorrect placement
Undersized or of poor quality

Delayed Union
Non-union
Sequestrum and involucrum - 61What does hypertrophic bone activity appear like?Elephants food
Indicates lack of stability - 62What increases the risk of surgical infection?Long surgeries, implant use, tissue trauma
- 63Why does implant use increase the risk of surgical infectionAllows biofilm to form which harbours bacteria and the body cannot fight
If the immune system is compromised or there is movement bacteria is release and spread haematogenously - 64What is done to reduce the risk of sruvial infection?High dose of IV cephalosporin at induction
- 65What type of fracture still has a high risk of infection despite proper care?Grade 3 open fracture - skin, muscle and ligament removes with a possible open joint
- 66What should be done with an open fracture to reduce contamination?Cover as soon as possible
Only use sterile equipment
High hygiene standards to prevent contamination from hospital bacteria - 67What is a dystrophic non union?Bone has been remodelled at the end
- 68What is the different types of inactive non unions?Dystrophic, necrotic, defective, and atrophic
- 69What is a defective inactive non union?May not try to bridge the bone gap
- 70What is atrophic inactive non union?May never heal completely
- 71What is inactive non unions common in toy breeds?Small amount of blood supply from muscle and medullar cavity
- 72What is most important for recruitment of new blood supply for bone?Extra osseous muscle
- 73How do toy breed fractures heal?Primary bone healing - anatomical reconstruction and complete immobilisation (plate)
- 74What are the different types of plates?Compression, neutralisation, bridging
- 75Where should the plates be placed?On the tension side of the bone
- 76What is a compression plate used for?Load sharing transverse or very short oblique
- 77What is a neutralisation plate used for?Oblique fractures to stop rotation
- 78What does a bridging plate do?Takes all the load across a fracture
- 79What size should a bridging plate be?The entire length of the bone
- 80What should be done before you do the lateral fabellar suture?Arthrotomy to examine ligament and meniscus for damage
- 81How do you preform a lateral fabellar suture?Pass suture around cranial half of fabellar proximal to distal
Drill hole with IM pin through tibial crest from lateral to medial
Crimp suture - 82What can be used to repair the tendon and ligament?3-loop pulley or locking loop suture
- 83What type of instrument is this and what is it used for?Jacobs chuck
IM pin insertion
- 84What type of repair is this?Hemi-cerclage

- 85What type of repair is this?Inter-fragmentary K wires
