Definition (Neer)
 = Abnormal amount of excursion of the humeral head on the glenoid in all directions 

Classification - Neer
Group I   Antero-inferior dislocation / Posterior subluxation
Group II   Postero-inferior dislocation /Anterior subluxation
Group III   Global dislocation

Definitions

  • Instability = a symptom, usually one direction
  • Laxity = a sign, usually multidirectional
  • Multidirectional Instability - VERY Rare

Stanmore Classification (Bayley Triangle)

Examination

  • Laxity - using Cofield's technique
  • Gagey Test for Inferior capsule
  • Muscle Patterning
  • Kinetic Chain
  • Generalised Hypermobility (Beighton Score)

Investigations

In all cases: X-Ray (AP and axillary views), MR Arthrogram

If indicated: CT scan, EMG's, EUA & Arthroscopy

Decision Making

  • Polar Type I = Surgery (+ rehab)Management
  • Polar Type III = Specialist Shoulder Physiotherapy
  • Polare Type II = combination of above (needs skillful and careful management)

Shoulder Therapy
Concentrates on:

  1. Core stability
  2. Scapula Stability
  3. Muscle patterning
  4. Proprioception
  5. Functional Rehab.

Combined Rehab exercises incorporate Core stabilty, Proprioception, Scapula, ROM, Strength

Surgery
Treat ALL Pathology present:

  • Labral (Anterior, Posterior, Superior)
