MS exam 2: Shoulder instability; surgical interventions and rehab

Anterior instability Non-anatomic surgeries:-Putti-Platt/Magnuson-stack-Modified Bristow/Latarjet

-Putti: shorten/advances subscaplaris to decr ant dislocation-Bristow: transfer coracoid tip to anteroinferior glenoid neck

What are the Pros/cons of non-anatomic anterior instability procedures

Pros: prevents dislocaioncons: -does not restore normal motion-loss of ER-inability to return to throwing sports

Describe a Bankart lesion

-labral tear-stretching of anterior-inferior capsule and IGHL-poriosteal stripping of subscap from neck of glenoid fossa

Anatomic Anterior instability repair:-Bankart repair-indications?

Reattchment of avulsed anterior capsule to glenoid rim-Make vertical incision along ant axial fold-subscap tendon divided Indications: -symptomatic recurrent anterior shoulder dislocations -failed conservative therapy-only helpful for unidirectional anterior instability

Contraindicaitons for Bankart repair

-voluntary instability w/emotional/psychological problems -seizure disorder-multidirectional instability

What are the factors impacting rehab for Bankart repair?

-open procedure or arthroscopy-method of fixation (sutures or anchors)-concomitant procedures (capsular shift; thermal shrinkage)

What are the rehab precautions w/ an open Bankart repair?

-avoid early agressive motion and activities -avoid excessive ER and extension-Avoid resisted or foreceful IR-lengthy immobilizaiton

For an open Bankart Repair, how do you treat motion?

-immediate to tolerance -ER/IR in scapular plane (45 deg abd initially --> 90 wk 5)-Gradual incr in shoulder elevation wk 2: 0-100wk 4: 0-155wk 6: 1-180

How do you treat strength for an open Bankart repair?

-submax isometrics immediately (rhythmic initaiton and stab)-isotonics wk 3-plyometrics wk 10

When can you start functional activities w/an open Bankart repair?

-sport specific training at week 12-14-contact sports at 5 months-overhead sports after 6-7 months

What are the rehab precautions for arthroscopic Bankart repair?

-sling for 6 wks (out for ROM; sling continues for comfort >6 wks)-no overhead motion for 4 wks-sleep in immobilizer for 4 wks-no excessive ER or ext for 4 wks slower rehab than open

How do you treat motion for an arthroscopic Bankart repair?

-immediate in scapular plane-ER/IR at 30 deg ABD-Elevation to 90 for 3 wks (stress to inferior capsule; progress to 135 deg wk 6)-Full ROM by wk 12

Arthroscopic Bankart repair Phase 1 rehabilitation (0-6 wks)-goals?

-maximal protection-absolute immobilization (0-4 wks)-achieve staged ROM goals (AAROM; scap retraction)

What are the milestones to continue to Phase 2 (6-12 wks)?

-appropriate healing-staged ROM goals achieved -min to no pain w/ROM (0-2/10)

What are the interventions for Phase 2 rehab for arthroscopic Bankart repair?

-cross body stretching for IR-scapular stability-elevation in scapular plane (full can): minimal capsular tightness; subacromial clearance; optimal length-tension RC/scap

What are the milestones to reach phase 3 (12-24 wks)?

-full ROM w/o substitution -good dynamic scapular control-strengthening w/ 0-2/10 pain

What are the goals for Phase 3 rehab?

-normal strength, endurance and neuromuscular control and power-gradual stress to anterior capsulolabral structures-gradual return to full ADLs, work duties, recreational activities

What is the intervention for Phase 3 rehab (12-24 wks) for arthroscopic Bankart repair

-Progressive strength/endurance (high speed/multi-planar)-Neuromuscular control-Activity specific interventions (work, sport, hobbies)-core and scapular stability-plyometrics (overhead athletes)

What are the milestones to return to full activity after an arthroscopic Bankart repair?

-MD clearance-No pain/full ROM-no sensation of instability-adequate RC/scap strength w/o pain

T/F: conservative treatment of anterior instability has lower recurrence rates than surgical repairs

false: both surgical repairs have lower recurrence rates (both forms of Bankart repairs)

Which repair is better: open or arthroscopic Bankart repair?

-argued that open might be better for athletes, but overall conflicting evidence and not a significant dif in success rate

Anatomic Anterior instability repair: Capsular shift/capsular plication-What is it?-Indications?-pros/cons?

-corrects anteroinferior GH jt instability; labrum is intact-indication: atraumatic instability-Pro: addresses lax structures w/o compromising ROM-con: posterior translation

T/F: Arthroscopic capsular plication is the most common procedure for anterior-inferior instability. Capsule is shifted superiorly and capsule repaired to intact labrum

true

What is thermal shrinkage for anterior instability?

-rarely done anymore-probe used to heat capsule and ligaments to tighten them-unidirectional only-poor long term outcome due to failure
