1 NON TRAUMATISK SKULDERSMERTE Impingement et entydigt begreb? FLERE PATOLOGISKE TILSTANDE maj rotatorcuffen. kapsulolabrale apparat. caput longum bicipsitis Speciallæge Arne N. Gam

2 EPIDEMIOLOGI. alder. ensidigt monotont arbejde. overhead aktivitet Tungt industri arbejde Sigholm G 1994 Arbejde over skulder niveau Palmerud 1995 Repetitivt arbejde - monotont Campell 1991 Håndgreb - Rotatorcuff musklerne (stabilisatorer) var mere øget end m. deltoideus Sporrong 1995, badminton, håndbold, volley: 8%/år. svømning: op til 87% over hele svømmekarrieren

3 Histiologi Glycosaminglycan infiltration Fibrocartilaginous transformation Tab af tenocyter Forkalkning (kadaver undersøgelser) Chard MD 1994 Riley GP 1994 Tendinit vs Tendinosis Angiofibroblastic hyperplasi (arthroskopisk) Ruptur

4 INSTABILITETENS CIRCULUS VITIOSUS (instability complex. Jobe, 1989) repetitive stress microtrauma to capsule attenuation (svækkelse) of capsule mild instability fatigue of rotator cuff anterior translation of humeral head secondary mechanical impingement rotatorcuff lesion

5 ANTERIOR SHOULDER PAIN IN THROWING ATHLETES Classification (Jobe 1989) I: Pure impingement, no instability ( > 35 years) II: Primary instability due to chronic labra microtaumata, and secondary impingement III: Instability due to hypermobility and subsequent impingement IV: Pure instability, no impingement (trauma)

6 CLASSIFICATION OF IMPINGEMENT AND INSTABIITY (Belling Sørensen, 2000) I: Pure impingement, no instability ( > 35 years) II: Instability and impingement. Functional instability. Unilateral instability. Multidirectional instability III: Pure instability, no impingement (trauma)

7 ROTATOR CUFF SYNDROM SYMPTOMER Smerter Bevægeindskrænkning Udstrålende smerter lateralt på overarmen Painful arc

8 ROTATORCUFF SYNDROM DIAGNOSE Ømhed (tub. majus, akromion, lig. coracoakromiale) Muskeltests Neer Impingemens tests Impingement relief test (SA-injektion) Hawkins

12 INTERN IMPINGEMENT Impingement mellem den posterosuperiore del af labrum glenoidale og rotatorcuffens dybe side Eneste fund hos 17 patienter med uforklaret skuldersmerte (Walch et al. 1992)

13 LÆSIONER AF DET KAPSULOLABRALE KOMPLEX SYMPTOMER Instabilitet Klik, catching, aflåsning, Snurren, smerte Dead arm syndrome Impingement

14 Læsioner af det kapsulabrale Komplex Diagnostik Instabilitet Apprehension Relocation Active compression test Biceps load test (SLAP)

15 SLAP LESION BICEPS LOAD TEST Author n (patients) sens. spec. Kim 75 (64 SLAP) (Am J Sports Med 99) Superior labrum anterior posterior

16 LABRUM LESION ACTIVE COMPRESSION TEST Author n (patients) sens/spec sens/spec labrum AC O Brien /99 100/97 (53 labrum, 55 AC abnormality) (Am J sports Med 98)

17 APICAL OBLIQUE PROJECTION - presence or absence of dislocation - glenoid fracture - Hill-Sachs lesion (Brems-Dalgaard 90, Sloth 89, Schydlowsky 98, )

18 ULTRASONOGRAPHY OF LABRAL LESIONS Author n (patients) sens/spec Schydlowsky 29 (26 lesions) 88/67 (Eur J Ultrasound 98) Schifter 21 (19 lesions) 90/73 (Unpublished)

19 MR-SCANNING OF LABRAL LESIONS - Divergerende resultater BEDST MED - højfeltmagnet - T1 og T2 sekvenser - billeder i flere planer - EXPERIENCED RADIOLOGIST ALLERBEDST MED - MR arthrography

20 CAPUT LONGUM BICIPITIS SYMPTOMER - Smerter DIAGNOSE - Ømhed - Yergasons test - Palm-up test RADIOLOGI - UL - MR

21 I. KONSERVATIV BEHANDLING 1. Heling af det inflammerede væv - Aktiv hvile, NSAID, Steroid Injektions teknik ved skuldersmerter hvor? Hollingworth GR 1983 Tenderpoint vs. Lokalisation (bursa, intraarticulært) Svagheder ved studiet: Diagnoser usikre Manglende sikring af lokalisationen Usikre parametre (smerte?) 2. Træning A. 4 P: Protectors (rotator cuff) and pivoters (m. serratus anterior, romboideerne, trapezius) B. positioners (deltoideus), propellers (pectoralis major, latissimus dorsi) - Proprioception

22 BEHANDLING II. KIRURGISK - PARTIEL ROTATOR CUFF LÆSION. Arthroskopisk debridement 85% tilbagevenden til sport (Andrews, 1985). Subakromiel dekompression 56% tilbagevenden til sport (Burns, 1992)

23 BEHANDLING II. KIRURGISK - KAPSULOLABRALE LÆSIONER. Arthroskopisk debridement (flap læsioner) 93% excellent or good (12 patients) (Payne, 1993). Capsular shift (multidirektionel instabilitet) 88% excellent or good (26 shoulders) (Bak, 2000)

24 BEHANDLING II. KIRURGISK - KAPSULOLABRALE LÆSIONER. Bankart operation (unidirektionel instabilitet) Open: 97% excellent or good (Rowe, 1978) Arthroscopic: 42% failure (Green, 1995) 92% excellent or good (Gartsman,2000) Arthroscopic/open: 24 /18% failure, ns (Cole, 2000)
