48
What are the advantages of ultrasonography in the investigation of soft tissue injuries?
- Good for soft tissue assessment - Good for bony surface assessment e.g. for avulsions - Quick and easy - portable unit - GA not needed - Oedema of soft tissue injury provides excellent contrast
49
What are the weaknesses of ultrasonography in the investigation of soft tissue injuries?
- Expensive equipment - Experience in interpretation needed - 2D images obtained
50
Justify the use of radiography in the investigation of soft tissue injuries

52
What are the most common indications for use of arthroscopy, tenoscopy or bursography in the investigation of soft tissue injuries?
- More chronic management | - Or acute cases with wounds that may have resulted in septic processes in joint
53
When should ultrasonography of soft tissue injuries be carried out and why?
- Repeat ~7 days after injury in order for fibres to become more destroyed by proteinases, macrophages, more oedema will be present allowing better contrast - Allows assessment of full extent and progression of damage
54

- Thickened SDFT - Soft swelling of the SDFT (change in texture, more spongy) - Pain on gentle pinching
57
Describe the common ultrasound findings in a case of superficial digital flexor tendonitis

60
Give the approximate severity, time out of training and prognosis for return to racing for an SDFT lesion where the total lesion CSA/total tendon CSA = 16-25%
- Moderate severity - 11 months out of training - 30% prognosis for return to racing
61
Give the approximate severity, time out of training and prognosis for return to racing for an SDFT lesion where the total lesion CSA/total tendon CSA = >25%

62
Outline the value of ultrasonography in monitoring the progression of SDFT injury
- Used for management of re-initiation of training and intensity - re-scan before increasing/changing exercise - Re-scan every 2-3 months and before any change in exercise - If >10% increase in CSA, reduce exercise level
63
Compare the occurrence of particular tendon injuries depending on the work done by the horse
- SDFT rupture more common in racehorses | - Suspensory ligament rupture more common in dressage or show jumpers
64
Describe the normal ultrasonographic appearance of the suspensory ligament
Heterogenous due to presence of ligamentous fibres, muscle fibres and fat
65

- Rare to palpate swelling/heat as is deep to other soft tissue structures and surrounded by fascia - Pain on deep palpation - Diagnostic analgesia and imaging findings (ultrasound +/- MRI) - Usually present with lameness, uni or bi lateral
66
Describe the diagnosis of proximal suspensory ligament desmitits in the forelimb

Bandage and dorsal splint
85
Outline the emergency treatment of all tendon/ligament injuries
- Stabilise limb, restore biomechanical function by creating alignment of single bony column and reduce pressure on soft tissues - Local wound care - Antibiotics and anti-inflammatories
86
Briefly describe the characteristics of healed tendons
- Stiffer than normal tendons as tendons fibrose rather than regenerate - Less efficient energy store leading to poorer performance due to limited elastic energy storage
87
Outline the acute phase treatment of tendon/ligament injury in the horse
- Physical therapy: cold, compression, rest - Medical: NSAID analgesia e.g. phenylbutazone and anti-inflamm, steroids controversial (can be used short term to reduce initial inflammation)
88
Outline the subacute phase treatment of tendon/ligament injury in the horse
- Fibroplasia phase - Mobilisation: early and progressive, train tenocytes back to normality, passive manipulation if on box rest, mobilisation from 7-14 days onwards ideally - Monitor with ultrasonography (CSA, fibre pattern)
89
Outline the chronic phase treatment of tendon/ligament injury in the horse
- Remodelling - Controlled ascending excercise - Ultrasonographic monitoring
90
Outline some examples of treatment options for tendinitis
- Stem cells (mesenchymal stem cells), must be used in acute phases - Platelet rich plasma - provides biological scaffold as well as containing cytokines, proinflamm growth factors etc. that may promote healing
91
Outline how tendonitis can be prevented
- Maximise quality of tendon prior to skeletal immaturity (tendon training of immature horses) - Reduce degeneration after skeletal maturity (avoid tendon training) - Reduce risk factors for tendonitis (decreased speed, fatigue, jumping, weight, improve ground surface, shoeing) - Detect tendonitis early with ultrasound and structure training around this
