Q

Rotator cuff syndrome: vascular reaction

A

In attempt to repair torn tendon, new blood vessels grow in + calcium deposits are re absorbed
This reaction may cause congestion + P

Q

Surgical treatment of rotator cuff tear

A

If Pt has useful ROM, strength + well-controlled P, no operative measure appropriate
If symptoms do not subside 3 months, consider operation
Indication more pressing if evidence of full tear in young person
Decompress rotator cuff by removing structures pressing on it
Procedure allows for early rehab

Q

Repair of tears

A

Indicators for operative repair are chronic P weakness of shoulder, signs ant loss of function
Younger + more active= greater justification for surgery
Procedure either open or arthroscopy
Advantages of arthroscopy - no soft issue damage, faster rehab, better cosmetic appearance

Q

Posterior instability

A

May persist after acute post dislocation
Usually takes form of subluxation rather than full dislocation
When arm is held in flex + IIR

33
Q

Post instability treatment

A

Treatment usually conservative Muscle strengthening exercises + voluntary control of Jt
Operative reconstruction indicate only if disability is marked, no gross Jt laxity + structural abnormality found using CT/MRI

34
Q

Atraumatic instability treatment

A

Usually treated by Pt to strengthen muscles + restore proprioception

Occasionally surgery needed to tighten capsule

35
Q

Example of Atraumatic instability

A

Voluntarily subluxation or dislocate their shoulders
Can become involuntary
Treatment requires physiotherapist + sometimes psychological counselling
- surgery should avoided

36
Q

Disorders of GH Jt- TB arthritis

A

Uncommon in shoulder
Usually starts as osteitis rarely diagnosed till arthritis has intervened
Pt usually adults
Constant ache + stiffness lasting many months
Striking features include muscle wasting around the shoulder

37
Q

TB arthritis treatment

A

Anti-TB drugs
Rest until acute symptoms have settled
Movement encouraged
If repeated flares, or if articulate surfaces are destroyed, Jt should be arthrodesed

38
Q

Disorders of GH- RA

A

AC, GH + synovial pouches commonly involved in RA
Chronic synovial leads to rupture of rotator cuff + Jt erosion

Pt usually has generalised arthritis, complaints of P + difficulty with tasks which involve lots of movement
Passive movements are painful + marked with crepitus

39
Q

RA treatment

A

In general, measures do not control synovitis, corticosteroids may be injected
If synovitis persists, surgical options are available

40
Q

Disorders of GH- OA

A

Usually secondary to other obvious disorders (local trauma, long standing rotator cuff lesion, rheumatoid disorders, a vascular neurosis of head of humerus)

Pt usually 50-60
History of previous shoulder problems
Most typical sign= progressive restriction

Analgesics, anti-inflam relieve P, exercise may improve mobility

41
Q

Rapidly destructive shoulder arthropathy epidemiology

A

Crystal induced, rapidly progressive arthopathy
Sometimes associated with massive tears of rotator cuff

42
Q

Clinical presentation of rapidly destructive arthopathy

A

Swelling
X-ray shows bizarrely destructive form of arthritis
Similar conditions encountered in other Jts

43
Q

Prognosis of rapidly destructive arthropathy

A

No satisfactory treatment
Arthroplasty may relive P but will not improve function because Jt is unable

44
Q

Congenital elevation of scapula

A

One remains higher than other- visible by 3 months of life
Smaller than usual + somewhat prominent
Abduction limited
Associated symptoms- Fuchs on of Csp, kyphosis or scoliosis likely
Mild cases left untreated
Marked limitation of abduction or severe deformity= operation

45
Q

Klippel-Feil syndrome

A

Rare congenital disorder
Compromises bilateral failure of scapula descent + fusion of several Csp vertebrae
Neck usually short + may be webbed, Csp motion limited
Condition usually left untreated

46
Q

Winged scapula

A

Scapula just under skin, like small wing
Due to weakness of serrated anterior (stabilises scapula on thoracic cage)
May cause asymmetry of shoulders, often not apparent until Pt contracts serrated ant against resistance

Can gradually improve
Even if it doesn’t, disability usually slight
Can be stabilised by tendon transfer

47
Q

Weakness of serrated anterior may arse from..

A

Damage to long thoracic nerve
Injury to brachial plexus of 5-7 nerve roots
Viral infection of nerve roots
Certain types of muscular dystrophy

48
Q

Grating scapula

A

Found in about 1/3 of normal people
Cause usually not found but occasionally an X-ray will show osteochondroma
Involves popping, grating, grinding or snapping of bones + tissue in the shoulder blade area when lifting or moving the arm

49
Q

AC instability

A

Common, resulting from dislocation of AC + rupture of ligaments which surround end of clavicle
Pt may complain of discomfort + weakness during strenuous with arm above shoulder

On exam, fairly obvious bump over AC+ Direct pressure may be painful
If diagnosis not obvious on x-ray, re-exam with Pt standing + holding heavy object will drag shoulder down + show displacement

Condition causes little disability during non-strenuous activity + treatment unnecessary

50
Q

OA of AC

A

Common in elders
Develops spontaneously
When it occurs in younger individuals it may be due to previous injury or repetitive stress
Pt complains of P over top of shoulder, particularly whilst using arm above shoulder height
Tenderness + localised swelling to AC

If analgesics + corticosteroid injections are ineffective, P may be relived by excision of lateral end o clavicle

51
Q

Tendinitis/bursitis/sub acromial impingement

A

Subacromial impingement= rotator cuff tendinitis or bursitis

52
Q

Subacromial impingement epidemiology

A

Irritation of rotator cuff underneath acromion
Exact cause unclear
Born with ‘hooked acromion’ will predispose impingement
Intrinsic rotator cuff weakness

53
Q

Age groups affected by subacromial impingement

A

> 40

54
Q

Risk factors of subacromial impingement

A

Sport
Work related activities (overhead motion)

55
Q

Clinical presentation of subacromial impingement

A

Inflam of bursa between rotator cuff + acromion
Recent Hx of over activity
P on top of shoulder
Localised tenderness, inflam, oedema, loss of function
Most symptoms begin gradually, have chronic component that progresses over several months
Bursitis can cause crepitus
Assess Csp for radiculopathy

56
Q

Prognosis of subacromial impingement

A

Best initial intervention= activity modification, NSAIDs, subacromial injections, PT program
Arthroscopy for failure of conservative treatment- 3-6 months- + impingement

57
Q

Calcification tendinitis

A

Multi focal, cell-mediated calcification of tendon usually followed by spontaneous resorption

58
Q

Epidemiology go calcification tendinitis

A

Build up on calcium in tendon
Genetic predisposition
Abnormal cell growth
Bodily production of anti-inflam agents
Metabolic diseases, such as diabetes

59
Q

Age groups affected by calcification tendinitis

A

40-60
Women more likely to be affected

60
Q

Risk factors of calcification tendinitis

A

Perform lots of overhead motions
More common in people who play sports routinely
Can affect anyone

61
Q

Clinical presentation of calcific tendinitis

A

May have minimal/no symptoms during formative phase
Acute symptoms common in restorative phase, P related to increased intratendinus pressure from influx of inflam cells, oedema, swelling, etc
Increased tendon vol= increased restriction of subacromial space
Examine Csp

62
Q

Acute phase of calcific tendinitis

A

Painful catching caused by localised impingement of calcified mass of coracoacromial arch, can easily be confused with acute infection

63
Q

Chronic phase of calcific tendinitis

A

Supra/infraspinatous atrophy, severe P due to guarding against motion
During this provocative tests such as impingement can be nearly impossible due to significant loss of motion

64
Q

Prognosis of calcific tendinitis

A

PT, NSAIDs, steroid injections
Calcific deposits remain, symptoms will resolve
Daily exercise program to avoid mobility loss
Surgery suggested when- symptoms progress despite treatment (3-6 months refer), when P interferes with daily activity

65
Q

Clinical presentation of calcific tendinitis

A

Should P on top
Movement aggravates (specifically horizontal direction)
Typical complaints include inability to sleep on affected side
Overall should have nearly full but painful ROM

66
Q

Prognosis of calcific tendinitis

A

NSAIDs
Intra-articulate injection of cortisone
Surgical excision of JT if P persists
Refer at 3-6 months

67
Q

Frozen shoulder/adhesive capsulitis epidemiology

A

Capsule thickens + tightens around Jt, restricting movement
