Achillies tendon treatment conservative

A

Reduce re-rupture rate 4/100

Q

Types of ACL surgery

A
  • Autografts – tissue from patients’ own body.
  • Allografts = tissue from donor (revision surgery)
  • Hamstring graft = might have some weakness in hamstrings, this graft is a lot looser and more lax
  • Patella graft = stronger, trouble with extension and PFPS

Q

Types of THR surgery

A

Posterior - glute max fibres dissection (hip extension) –> high dislocation rate
Anterior - TFL and sartorius muscles
Anterolateral - TFL and glute med –> can have limp (medium dislocation rate)
Lateral - splits TFL to get through to glute med –> Trendelenburg, nerve damage = hip abductor weakness (lowest dislocation rate)

Q

When is a Open RC Repair used and when would arthroscopic performed

A

Large or complex tears where the tear is completely retracted off the bone or needs greater access to the torn tendons.
Arthroscopic is smaller procedures and tears –> can even be to just have a look but is become more popular for all RC tears

Q

Non-Modifiable risks for ACL Injury

A

Gender
Variations in bone morphology
Neuromuscular control
Genetics - CC genotype variant in COL541
Hormones
Previous ACLR

20
Q

Modifiable risks for ACL injury

A

Young playing age
Weather
Friction (number of cleats)
Earlier, more intense and more frequent participation in sport

21
Q

KANON Trial

A

I found no difference between the knee being surgically reconstructed earlier or late there is just risk that patient will need surgery later down track and will take longer for recovery

22
Q

SNAPP

A

Better 18month outcome with those that had early recon compared to delay –> due to recovery time I assume

23
Q

3 types of ACL treatments

A
  1. ACLR followed by rehab
  2. Rehab first line of treatment and then surgery if patient develops functional instability
  3. Preop rehab and ACLR (not to be used with meniscal tears)
24
Q

What is the Weber Classification

A

Weber A - #’s inferior to syndesmosis, usually stable and able to do conservative Mx

Weber B - #’s at the level of syndesmosis can be stable or unstable depending if Medial Malleolus # or deltoid ligament injury or syndesmosis intact or not, may need ORIF

Weber C - #’s above syndesmosis, syndesmosis is not intact, Medial and deltoid injury, ORIF required due to unstable

25
WEBER B Mx
Traditional cast compared to foot orthosis is just as effective for ankle function and fracture healing as the conventional 6 week immobilisation in a cast --> shorter immobilisation could be viable option for patients (short term is close enough in effectiveness to the long term)
26
Precautions after THR
No twisting of the leg Leg to not cross the midline of the body No hip flexion past 90º No hip extension past netural PWB no excessive hip ABD Avoid reaching across Must get in and out of bed on the operated side --> 6 weeks usually
27
Progression of Assistive Aid
FASF 2WF Pick up frame Crutches stick
28
Difference between WB post THR or ORIF
THR - WBAT from day 1 ORIF - NWB (6-8/52) - PWB (8-10/52) - FWB (10-12/52)
29
Evidence for traction
NICE and AAOS guidelines do not recommend traction as pre-surgery Tx due to lack of efficacy and surgeons can now get more stability in the Sx itself
30
ACDF Surgery precautions and instructions
Must: Log roll Wear cervical collar if told for 2/52 Wear Philadelphia collar or soft collar 48hrs unless an exception Sleep on the firm pillow to support the neck Change positions regularly See a Dr if red flags become present DO NOT: Get the surgical site wet lift arms above 90º  Do not lift anything heavier than 1.5kg Do not bend, twist, lift Do not sleep with arms overhead Do not spend all your time in bed Do not drive until cleared Do not perform strenuous activities
31
Evidence for Cervical Spine Surgery
At the 2-year mark, there is no significant difference between arm pain and function in the conservative group. Surgery has massive improvements in pain and neck disability index in the first year but evens out by year 2. Surgery = speed recovery and reduce pain faster (comes with complications)
32
Standard precautions following LSF
Do Not Do: No bending, lifting or twisting No lifting more than 5kg No driving unless cleared No over extending No prolonged sitting for >30-60mins Must: Incorporate log rolling Gradual Ambulation Stabilisation exercises for breathing and relaxation (extensor spinal muscle)
33
Referral - Pseudoarthrosis
Inadequate unloading to allow healing to occur in the fusion site or because of a delay in diagnosis. Interrupts the bones ability to heal, creating a scar tissue to form in between like a fibrous joint. - can have axial radicular pain - widespread pain around the abdomen - strange and persistent neurological pain
34
Referral - DVT
Blood clot that forms within the deep veins due to immobilisation 9can travel proximally - Odema - red and hot skin with a dilated vein tenderness - Wells scoring ≥2
35
Referral - Infection
Pain (insidious 1 month post-op swelling or erythema at the incision wound dehiscence and purulent drainage from wound
36
Referral - Cauda Equina Syndrome (L1-L5)
Spinal cord is so compressed --> lower region (lumbar spine) - urinary retention - radicular pain down the back of legs - Reduced anal sphincter tone severe low back pain - Sensory loss - Sexual dysfunction
37
Sx VS Cx for lumbar spine fusion
Surgery is preferred as it provides faster pain relief, improved QOL, and functional improvement and is essential for those with severe conditions. Conservative treatment can be used for low severity patients --> will clinically see more improvement with fusion.
38
RCT Surgery Precautions 0-4/52
No pushing, pulling or lifting No shoulder extension, abduction or IR No overhead movements No excessive stretching or sudden movements Sling must be worn 24/7 for the first 6 weeks No sleeping on the affected side Wound Mx keep the incision dry/ use shower sling No BW through arms or hands or leaning on both elbows No muscle activation for 6-8/52
39
Subacromial Shoulder Pain - arthroscopic Subacromial decompression
Surgery group had better outcomes in terms of functionality, pain compared with no treatment but was not clinically significant--> surgery is a quick fix at the end of the day Either surgery does the job and neither are superior of each other.
40
Physiotherapy Repetitive Exercise compared with best practice
PRE was not sueprior Corticosteroid injections had no long term benefit
41
Non-traumatic RC tear
Conservative treatment is a reasonable option for the primary initial treatment for isolated, symptomatic, non-traumatic, supraspinatus tears in older patients. --> There was no clinical difference between the three interventions
42
Definition: Mean Difference
The bigger the mean difference the better = will depend on what the clinically significant number is
43
Definition: clinical worthwhile effect
Determine how much of a change is needed
44
Definition: Confidence Interval 95%
The smaller the confidence interval, the better, as it means there is a smaller chance the researchers have got it wrong for which outcome is better
45
12 factors that affect Rehab after RC repair --> may give in relation to other joint
1. Surgical approach 2. Size of tear 3. tissue quality 4. fixation method 5. location of tear 6. type of tear 7. mechanism of failure 8. timing of surgery 9. characteristics of the patient 10. RC tissue quality anterior and posterior of tear site 11. Access to care 12. Physiotherapy philosophical approach
46
Achilles Tendon Rehab
Wear Cam boot 24/7 for 2 weeks 2cm heel lift for 6-8 weeks, reducing the height. Cam boot must be worn for 3 months total
47
RC Tear Rehab
On for 24/7 for the first 6 weeks Can remove sling when resting or sitting with the arm by side Remove arm from the sling 3-4x/day to bend and straighten your elbow → arm needs to be supported however throughout
