Summary

This MedED lecture, scheduled on 19th September 2024, dives deep into MSK and Rheumatology, with a particular focus on PACES. The on-demand teaching session will cover common presentations and differentials for each joint, principles of joint examination on the hand, knee, and shoulder, special tests for each joint, and X-ray interpretation for MSK pathologies. The session will also delve into other rheumatological conditions, like SLE, PMR, and AS. Using interactive case studies like that of a 6-year-old with sickle cell disease presenting knee pain, the session promises to be practical and engaging. Medical professionals will benefit from this session, enhancing their expertise in managing similar cases in their practice.

Dd an i e ll a . s o u s s i 1@ n h s . n e t MSk and Rheumatology PACES MedED Lecture – 19/09/2024SESSION STRUCTURE • Common presentations and differentials for each joint • Principles of joint examination: Hand, Knee and Shoulder • Special tests for each joint • X-ray interpretation for MSK pathologies • Other rheumatological conditions e.g. SLE, PMR, AS SBA 1 Johnny, a 6 year old child with sickle cell disease presents to paeds A&E complaining of knee pain. When you see him, you see that he tries to avoid putting weight on his knee, and has a temperature of 38.6 degrees. What is the next best step in management? A) Obtain blood sample including WCC, CRP B) Conduct joint aspiration and send sample off for MC&S and crystals C) Prescribe antibiotics D) Sent Johnny home with simple analgesia E) Obtain a joint x-ray SBA 1 paeds A&E complaining of knee pain. When you see him, younts to Common organisms: see that he tries to avoid putting weight on his knee, and has 1. Staph aureus a temperature of 38.6 degrees. 2. Strep pneumoniae 3. Salmonella species in sickle cell What is the next best step in management? patients A) Obtain blood sample including WCC, CRP (of secondary use) Cardinal signs of septic arthritis: MC&S and crystals (septic arthritis until provenfor • Hot otherwise) • Swollen • Painful knee C) Prescribe antibiotics (will do eventually) • Inability to weight D) Sent Johnny home with simple analgesia bear E) Obtain a joint x-ray (MRI would be better but even still • Temperature pathology will not show on imaging unless there is bone • Limited ROM involvement) Knee – Common presentations • Joint pain (acute and chronic) • Reduced range of motion Knee – Common presentations Joint pain (acute and chronic): • Osteoarthritis • Crystal arthropathy (esp. Pseudogout) • Ligamentous injury • Meniscal injury • Fracture • Septic arthritis Knee – Common presentations Reduced range of motion: • SEPTIC ARTHRITIS (painful swollen knee, cannot weight bear) • Fracture • Osteoarthritis Examination introduction Introduction (WIIPPPE) • Wash your hands • Introduce yourself (name and position) • Identity of patient (confirm name and date of birth) • Permission (consent and explain examination: “I’m going to examine your X now, is that OK?”) • Pain? • Position • Expose Knee examination Look, feel, move + special tests + gait Look: Feel: Move (active and Special tests: passive): • Anterior drawer (ACL) • Erythema • Sweep test • Joint swelling • Patellar tap • Flexion 0-140° • Lachman's test (ACL) • Scars • Joint crepitus • Extension -10-0° • Posterior drawer (PCL) • Deformity • Patellar tenderness or • Valgus stress (MCL) laxity • Muscle wasting (LMN, • Varus stress (LCL) disuse atrophy etc.) • Joint line tenderness – • Posteriorly – baker's cyst fracture, meniscal or • Patellar tracking collateral ligament injury • McMurray's (offer – • Fixed flexion deformity • Baker's cyst • Posterior sag sign assesses medial and lateral • Popliteal aneurysm menisci)Knee examination Knee exam presentation and further Ixs: *Today I examined X, a X-year-old M/F. On general inspection, the patient appeared comfortable at rest, with no signs of MSk disease. There were no medical paraphernalia around the bed. The patient had a normal gait and knee joint appearance. There was no joint crepitus and the range of movement of both knee joints passively and actively was within normal range. There were no abnormalities noted on the assessment of the ligaments of either knee joint. Special tests were negative. In summary, these findings are consistent with a normal knee joint examination. For completeness, I would like to perform the following further assessments and investigations:* 1. Neurovascular examination of both lower limbs. 2. Examination of the joints above and below (e.g. ankle and hip). 3. Further imaging if indicated (e.g. X-ray and MRI). https://geekymedics.com/knee-examination/Knee X-rays: Osteoarthritis LOSS: • Loss of joint space • Osteophytes • Subchondral cysts • Subchondral sclerosisKnee X-rays: Replacements https://bmcmusculoskeletdisord.biomedcentral.com/articles/10.1186 /s12891-019-2508-1 https://www.hss.edu/conditions_partial-knee-replacement.asp SBA 2 wrist.

Further examinations and investigations: • Neurological examination of Axillary nerve palsy upper limbs • Typically caused by shoulder dislocation. • Loss of sensation over the lateral deltoid region (regimental patch) • Examination of the joints above • Deltoid muscle weakness (loss of shoulder abduction). and below (cervical spine and elbow) • Further imaging if indicated (e.g. Shoulder impingement syndrome (SIS) X-ray, MRI). • Inflammation of rotator cuff muscle tendons as they pass through the subacromial space. • Most often associated with supraspinatus tendonitis. • Symptoms include pain, weakness and a reduced range of active movement. • Normal passive range of motion is preserved. • Symptoms exacerbated by overhead movement of the limb, typically during abduction between 60-120°, which is referred to as a ‘painful arc’ of movement. https://geekymedics.com/shoulder-examination/X-ray findings SBA 3 Samantha, a 72 year old retired seamstress presents to you in the GP clinic complaining of pain in her hands.
