Bankart Repair By: Abbie Mitchell, Brian Bartow, Jordan Anderson, & Tyler Pecha
BackgroundPathology/Etiology: • What is a Bankart Lesion? • A Bankart lesion is a traumatic detachment of the glenoid labrum . • Most common cause: Dislocation of the shoulder. • At the time of original injury, the humeral head is forced out anteriorly and inferiorly, first stretches the anterior capsule and the inferior glenoid ligament. • As a result of the traction from the inferior glenoid ligament, the fibrous labrum is pulled off from the anterior rim of the glenoid. • Seen in over 85% of cases after a traumatic anterior dislocation. • More common in younger (under 30 years old) individuals. • The inferior glenoid ligament is the most important stabilizer of the shoulder; The stretch of the ligament and the resulting Bankart lesion results in shoulder instability.
BackgroundProcedure: • When is the procedure performed? • Surgery is recommended with younger than middle age individuals who lead active lifestyles. • Biggest factor is chance for repeat dislocations. • Other factors: Patient’s pain, instability, lifestyle, and activities. • Approximate percentage for re-dislocation: • Under the age of 20 = 90% • Between 20-30 years old = 75% • Between 30-40 years old = 30%
BackgroundProcedure: • Traditionally, most orthopedic surgeons would not choose to operate on a patient after a first dislocation. Rather, after a brief period of immobilization, followed by physical therapy, the patient would gradually resume their normal activities. If the patient sustained a second, or recurrent, dislocation, then surgery was considered. • More recently, there is good scientific evidence to support early surgery, especially in young patients who are at a high risk for re-dislocation.
BackgroundProcedure: • Can be completed arthroscopically or via open surgical technique. • Involves reattachment and tightening of the labrum and ligaments of the shoulder. • Usually done using sutures and small bone anchors. • Surgeon will also smooth out rough edges of labrum.
Examination • AROM – guarding, compensatory movements, scapular kinematics (delayed until active motion is allowed). • PROM – guarding, pain • check incision – color, temperature, healing process, signs of infection, bandaging • palpation • pain • swelling • neurological changes – temperature, sensation, weakness • mechanism of initial injury • medical/surgical/injury history • medication compliance • PLF, CLF • occupation, hobbies, recreational activities • living environment • patient goals
Examination:Tests/Measures for ROM • inter- and intra-rater agreement for 5 different methods of assessing shoulder range of motion in 6 directions: • visual estimation • inter: 0.57-0.70 • intra: 0.59-0.67 • goniometry • inter: 0.64-0.69 • intra: 0.53-0.65 • still photography • inter: 0.62-0.73 • intra: 0.56-0.61 • stand and reach • inter: 0.74 • intra: 0.49 • hand behind back reach • inter: 0.26-0.39 • intra: 0.14-0.39 • fair-good reliability found for all methods except hand behind the back reach (poor)
Evaluation • functional outcomes assessment • DASH Questionnaire • Shoulder Pain and Disability Index • University of Pennsylvania Shoulder Score • American Shoulder and Elbow Surgeons Shoulder Form • Rowe Shoulder Score • comparison of examination findings to expected presentations • constant re-evaluation of patient progress • use non-operative side as a “standard” for comparison as able (after precautions removed)
Signs & Symptoms • pain • swelling • guarding • catching • tenderness to palpation • compensatory movements (ex: shoulder hike) • poor scapular kinematics • apprehension
Differential Diagnosis • Bankart Lesion: • is an avulsion of the anteroinferior glenoid labrum at its attachment to inferior glenohumeral ligament (IGHL) complex; lesion is felt to result from anterior shoulder dislocation and is felt to be primary lesion in recurrent anterior instability. • Hill-Sachs lesion: • impression fracture of the humeral articular surface caused by translation of the humeral head over the glenoid rim. Found in 85% of anterior dislocations. If >25% of the articular surface is involved allograft or autograft bone graft to repair the defect is indicated
Differential Diagnosis • SLAP (superior labral anterior posterior tear) • Acquired Posterior Capsular Contracture in throwing athletes leads to high torsional and shear stress on the posterosuperior labral in the late-cocking phase of throwing, which can produce a posterior SLAP lesion. Throwers may feel sharp pain in the extreme abduction/ER position followed by "dead arm" sensation and loss of throwing velocity. • History of falls directly on shoulder, downward force on outstretched arm, or sudden eccentric force on a contracting biceps.
Differential Diagnosis • Rotator Cuff Tear (RTC) • Anterior-Inferior Glenohumeral Instability • Athletes: instability may occur with repetitive external rotation with the arm in abduction (apprehension position). • ALPSA: • anterior labroligamentous periosteal sleeve avulsion; medialized Bankart with medial displacement of the torn anterior labrum. • Perthes lesion: nondisplaced labral tear • GLAD lesion: • glenolabral articular disruption: nondisplaced anterior labral tear associated with articular cartilage injury.
Differential Diagnosis • CORRELATION BETWEEN BANKART AND HILL-SACHS LESIONS IN ANTERIOR SHOULDER DISLOCATION • A total of 61 patients had an MRI • The MRI scans were reviewed and subsequently confirmed by a radiologist to show the presence or absence of BankartandHill-Sachs lesions • 73% had a Bankartlesion and 67% had a Hill-Sachs lesion on MRI • 64% of those with a Bankart lesion had Hill-Sachs lesions • 70% of those with Hill-Sachs lesions had a Bankartlesion • The correlation between Bankart lesion and Hill-Sachs lesion showed that if one of the lesions was identified, the chance of the other being present was more than two-and-a-half times as likely
Diagnosis/Prognosis • Guide to PT Practice- PT Diagnosis • 4I- Impaired Joint Mobility, Motor Function, Muscle Performance, and Range of Motion Associated with Bony or Soft Tissue Surgery • Prognosis • Following physician/PT directions both open and arthroscopic repairs have a good prognosis • Recurrance: • Marquardt, et al: 5.6% failure rate (arthroscopic) • Gartsman et al: 7.5% failure rate (arthroscopic) • Freedman et al: 12.6% arthroscopic vs 3.4% open • Failure to identify bony lesions through arthroscopy (4% failure rate when bony lesions excluded)
Problem list/Goals • Problem list • Pain • Decreased ROM • Decreased Strength • Swelling • Goals • Goals will be related to function and will address problems from problem list. • Will address different parts of problem list based on phase of recovery.
Sample Goals • Phase one (weeks 0-6): • Following PT intervention, pt will report decrease in pain to 2/10 at rest, in order to sleep through the night, within 2 weeks. • Phase two (weeks 6-12): • Following PT intervention, pt will achieve full shoulder AROM within 10 weeks in order to be independent in ADL’s. • Phase three (weeks 12+) • Following Pt intervention, pt will achieve equal strength, all motions bilateral shoulders, within 16 weeks in order to return to full work responsibilities as a mechanic.
Timeline • Stages of Tissue Healing! • Who knows them?
Timeline • Stages of tissue healing • Inflammatory stage (0-2 weeks) • Proliferation/Repair stage (days-6 weeks) • Maturation/Remodeling (up to 2 years!) • General Timeline • Return to strenuous work duties • Physician dependent • Generally around 4 months
Inpatient care • Today this is an outpatient surgery
Outpatient care Comparison of 4 different Bankart Repair protocols Consensus among protocols • Modalities as needed for pain/swelling • Sling until week 6 typically • ROM • Begin pain-Free PROM around week 2 • Brigham and Women’s Hospital: No shoulder movements of any kind until week 4. • Very slow progression of passive ER in scapular plane or at 90 degrees abduction. ER last to regain full motion • Joint Mobilizations • Avoid anterior glides to protect surgical repair • No AROM until around week 6 • Full AROM around week 10
Outpatient Care • Strengthening • Pain-free RTC isometrics around week 2 • Begin isotonic shoulder strengthening around week 6 • Slow progression of strengthening exercises • Avoid aggressive strengthening exercises that place stress on anterior capsule (i.e. bench press, push-ups • Equal strength bilaterally around week 14-20 • Return to sport/strenuous work duties • Physician dependent • Pain Free shoulder Function without signs of instability • Full AROM • Equal Strength Bilaterally
Outpatient care • Take Home Message • Slow and conservative rehabilitation • Number one priority • Protection of healing tissues!
Home Program • Post-op • Ice as needed for pain/swelling • Pendulums • Emphasis on correct form to ensure passive movements • AAROM elbow, wrist, hand • Wound care • Active Motion phase • HEP of specific strengthening/stretching activities • Progression of strengthening exercises as tissue healing occurs
Patient Education • Avoid active motion during first 6 weeks • Warn pt of over-compliance • Mechanism of injury • Re-emphasize mechanism as same mechanism is what will cause surgical repair to fail • I.E. forced external rotation and extension • POC • Including problem list, goals, timeline, prognosis • HEP and progression of HEP
