| # | Slide |
|---|---|
| 1 | Title slide – Radial Nerve: Anatomical Sites of Compression & Injury |
| 2 | Overview – Anatomy: Origin (C5–T1, posterior cord), triangular interval, radial groove, lateral intermuscular septum, division into PIN and SBRN, radial tunnel |
| 3 | Section header – Proximal compression sites |
| 4 | Site 1 – Axilla: Crutch palsy, honeymoon palsy, shoulder dislocation → triceps weak + wrist drop |
| 5 | Site 2 – Spiral Groove: Most common site; Saturday-night palsy, humeral shaft fractures; triceps SPARED; with intraoperative surgical image |
| 6 | Clinical Sign – Wrist Drop: Comparison of lesion levels, EMG findings; clinical photo |
| 7 | Site 3 – Lateral Intermuscular Septum: Mid-arm entrapment; with radiograph |
| 8 | Section header – Distal compression sites |
| 9 | Site 4 – Radial Tunnel / PIN Syndrome: LEAFS mnemonic (Leash of Henry, ECRB edge, Arcade of Frohse, Fibrous band at radial head, Supinator distal edge); with intraoperative image |
| 10 | Arcade of Frohse: Ultrasound & MRI features; PIN entrapment imaging |
| 11 | Sites 5 & 6 – Distal Supinator + Wartenberg Syndrome (SBRN): wristwatch compression, Tinel's sign |
| 12–13 | Comparison tables: Lesion level vs. clinical features (two-column layouts) |
| 14 | Diagnosis & Management: EDX, ultrasound CSA, conservative vs. surgical, nerve repair |
| 15 | Key Clinical Pearls: 6-row reference table |
