Q

shoulder pain treatment if pain is suspected from impingement

A
  • Oral NSAID course (4-6 wks), activity modification, physical therapy to strengthen rotator cuff and scapular musculature
  • Cortisone injection: subacromial, posterolateral approach: Diagnostic as well
  • No benefit from injection after 3-4 weeks then consider MRI to r/o tear of rotator cuff
  • Can give cortisone injections every 3-4 months

Q

why do we care about dislocations

A

o Buzz words associated with dislocations, instability and shoulder surgery
o When large both the Hill Sachs and Bankhart lesions may predispose patient to recurrent instability with external rotation and abduction of shoulder

Q

after shoulder dislocations are reduced

A

Orthopedic management: anterior

  • Anterior dislocation: conservative management
  • Short period of immobilization
  • Gradual advance to passive rom, then active rom, then advance to strengthening
  • Can be a long 3-5 month process
  • If continued instability 6 months plus after injury than refer to surgeon

Orthopedic management: posterior
-Not as common, I always review these with surgeon on first visit and defer to their treatment plan

Increased chance to repeat dislocation

33
Q

cubital tunnel syndrome diagnosis and treatment

A

Diagnosis
-Nerve Conduction Study

Treatment

  • Elbow pad to protect nerve
  • Splint for nighttime comfort w elbow in 45 deg flexion
  • NSAIDs
  • Surgical treatment: decompression (release) or ulnar nerve transposition

Release: the ligament “roof” of the cubital tunnel is cut and divided. This increases the size of the tunnel and decreases pressure on the nerve

Transposition: the nerve is moved from its place behind the medial epicondyle to a new place in front of it. This is called an anterior transposition of the ulnar nerve. The nerve can be moved to lie under the skin and fat but on top of the muscle (subcutaneous transposition), within the muscle (intermuscular transposition) or under the muscle (submuscular transposition).

34

52
Q

fracture care and follow up

A

o Initially fractures will be quite swollen and a splint is used for immobilization. If injury initially seen in urgent or primary care setting than patient is typically referred to an Orthopedic provider.
o Stable fractures typically follow up within 12-14 days for X-ray, diagnosis and treatment
o Unstable fractures should follow up within 1-3 days for X-ray, diagnosis, possible reduction, treatment which may include surgical intervention
o ALWAYS note neurovascular status when documenting!

53
Q

fracture care and follow up: stable vs unstable fractures

A
  • Diagnosed stable fracture can be immobilized in variety of ways: cast or splint most common
  • Diagnosed unstable fractures are typically immobilized in NWB cast or if post surgical NWB splint (remember swelling issue)

Stable fractures return to clinic at 4 week mark from date of injury (DOI) for X-ray to check healing
-If healing progress is shown than cast/immobilizer may be removed and a less restrictive modality may be considered as well as initiating WB if not already doing so.

Unstable fractures return to clinic often 1 week apart to check alignment of fracture by doing an X-ray in cast
-At 4-6 week mark depending on fracture, cast may be removed and new one placed. WB status may be considered, but if still questionable conservative treatment is typically to continue NWB modality.

54
Q

fracture care and follow up

A

o In general at 2 weeks out from DOI bone callus starts forming to the point where the bone gets sticky (knitting together). True evidence of bone healing not usually seen on Xray until approx 4 weeks out from DOI. By 8-10 weeks out from DOI smaller fractures are considered healed and may slowly begin normal activity as tolerated. If fracture has been reduced or in area of poor blood supply may take 12-14 weeks out from DOI.
o This is stuff you learn as you go, it always depends on who you are working with, where the fracture is and the type of fracture. But these are general guidelines that have helped me through my first few months alone in clinic.
o Always keep “when can I start range of motion?” in mind.
