Q

What is the pathophysiology of spondylolisthesis?

A

Spondylolisthesis occurs where one vertebra shifts forward over another.

Usually there is a preceding stress fracture of the pars interarticularis.

Pain is often caused by extreme stretching of the interspinous ligaments and/or the nerve roots themselves.

Q

How would you manage a patient with spondylolisthesis?

A

Refer to physiotherapy for a strict flexion exercise program for at least 3 months. (objective is to splint their own spine with abdominal and spinal muscle strengthening).

Avoid extension, especially hyperextension of the lower back.

Surgery in intractable cases (Also lumbar corsets in refractory)

IF PATIENT DEVELOPS new LUMBOSACRAL RADICULOPATHY or acute neurological deficit - IMMEDIATE neurosurgical review is needed.

Q

A young endurance athlete presents with calf pain which occurs during exercise. Pain is described as ache, squeeze tightness. Symptoms gradually subside with rest (After 20 minutes) and are minimal during normal daily activities. What is the most likely diagnosis? What is the pathophysiology?Ix? Management?

A

Chronic exertional compartment syndrome.

CECS.
Can be associated (after months/years) with tibial stress fracture.

A stiff/non compliant fascial compartment may underlie symptoms.

If not improving with conservative management for orhtopaedic review for pressure testing of fascial compartments and for consideration of fasciectomy/fasciotomy.

Genetic predisposition
Female sex
Aromatase inhibitor use
Occupational: repetitive work with flexed wrists

COMORBIDITIES - DM, Connective tissue disorders, Rheumatoid arth, Hypothyroidism, pregnancy, pre-exisitng median nerve mononeuropathy, granulomatous disease (eg TB), pagets disease, multiple myeloma, Amyloidosis, acromegaly, Tophaceous gout

21
Q

22
Q

CTS symptoms

A

Numbness and pain in the radial three and one half digits (including thumb).
Wakes at night with tingling/pain/numbness - shakes hands over end of bed and relieves symptoms.
Can get weakness of thumb abduction and opposition
Due to innervation of LOAF muscles - lateral two lumbricals, opponens pollicis, Abductor policis Brevis, Flexor pollicis brevis

23
Q

Examination findings in CTS?

A
  1. Check sensation in entire upper arm. Changes in sensation are a late change in CTS. The sensory changes occur in the distribution of radial 3 and 1/2 fingers but SPARE THE THENAR EMINENCE.

If thenar eminence is involved the lesion may be proximal to the carpal tunnel.

  1. In advanced CTS can get weakness of muscles of thenar eminence. Manifests as weakness of thumb ABDUCTION and OPPOSITION
  2. PROVOCATION TESTS
  3. Tinel (Tap)
  4. Phalens (Reverse pray)
  5. Two point discrimination test (high spec/low sens)
24
Q

Investigations in CTS?

A
  1. NCS - high sens/spec for CTS.
    (Not always needed)

Indications:

  1. PROGRESSIVE motor/sensory symptoms
  2. UNCLEAR DX
  3. WORK RELATED - do NCS and EMG to exclude other conditions.

NB: If shoulder, neck involvement may need cervical MRI

25
Q

Management of CTS?

A
Wrist splint.
Elevate forearm on pillow at night.
NSAID (ibuprofen) - (not in pregnancy)
Steroid Injection - pregnancy and lactation
Surgery - carpal tunnel release
26
Q

What are the indications for surgery in CTS?

A
  1. Moderate/severe changes on NCS
  2. Progressive motor/sensory symptoms.
  3. Not responding to conservative management
27
Q

What do you know about pregnancy related CTS?

A

Steroid injections may be appropriate instead of non steroidal oral therapy.

Usually resolves within 4 weeks postpartum. However can RECUR in menopause

28
Q

Key aspects of clavicular anatomy?

A
  1. AC joint - acromoclavicular
  2. SC joint - sternoclavicular

3 parts of the clavicle can be fractured.

Middle third - usually conservative - most common
Medial third - refer ortho and check for lung or intrathoracic injury - subclavian art/vein
Lateral third - displaced - refer

90% of clavicular fractures in kids are middle third

29
Q

Immediate management of every clavicular fracture?

A
  1. EXCLUDE damage to lungs (haemo/pneumothoraces), Scapular fracture, rib fracture, check both blood supply and nerves of brachial plexus - upper limb neurovascular status (All these can be damaged at high force).
  2. Pain relief.
  3. ICE to reduce bleeding to area for 48 hrs.
  4. Refer if indicated
  5. adults broad arm sling for 3 months
    Children broad arm sling for 6 weeks.
30
Q

When should you refer a clavicular fracture to ortho?

A

Neurovascular compromise
Lung injury associations - haemo/pneumothroaces
FLoating shoulder - ipsilateral clavicular and glenoid neck fractures
Complete displacement - displacement greater than one bone width
Communition of fracture
Open fracture
Shortening of 2cm
Lateral third clavicle fractures that are significantly displaced
Medial third clavicle fractures - refer to EMERGENCY for evaluation of associated head, neck, intrathoracic injuries (occurs in 90%).

31
Q

What are the most common complications of a middle third fracture?

A

Malunion - angulation, shortening and poor cosmetic result.

Serious Cx rare

32
Q

What is non union? Risk factors for non union in clavicular fractures?

A

Fracture fails to heal after 4-6 months.
RF’s - greater initial displacement, severe trauma, communition, shortening, primary open reduction, inadequate immobilisation, older age

33
Q

What’s a late complication occasionally associated with non union?

A

In mid and distal fractures - brachial plexus compression neuropathy from callus formation

34
Q

Most common complications of proximal third clavicular fracture?

A
  1. non union

2. post traumatic arthritis.

Patient can move shoulder satisfactorily through ROM without pain

37
Q

Return to sports in clavicular fractures?

A

Wait 4 to 6 weeks after clinical healing has occurred. (non contact)
8-12 weeks for contact sports

38
