Disc prolapse vs facet joint pain
Facet Joint Pain Typically presents with localised lower back pain, often worse in the morning and on standing. Pain exacerbated by lumbar extension and rotation. On examination, tenderness over the affected facet joints may be present. No radicular symptoms (no leg pain, numbness or weakness). Usually no neurological deficits. Imaging (X-ray/MRI) may show degenerative changes but is not diagnostic. Disc Prolapse Often presents with acute onset of back pain radiating down one leg (sciatica), following a dermatomal pattern. Associated with neurological symptoms: numbness, paraesthesia, weakness in affected myotomes. Pain worsened by sitting, bending forward, coughing or straining. Positive straight leg raise test may be present. MRI is the investigation of choice to confirm diagnosis. May have signs of nerve root compression on neurological examination.

100
Prepatellar bursitis vs Infrapatellar bursitis
Cause: - Prepatellar bursitis: Caused by repetitive direct pressure or trauma to the anterior aspect of the knee, typically from prolonged upright kneeling. - Infrapatellar bursitis: Results from repetitive kneeling with pressure on the area just below the patella, often associated with kneeling on bent knees. Presentation: - Prepatellar bursitis: Presents with swelling and tenderness over the prepatellar bursa (anterior to the patella). The swelling is superficial and may be fluctuant. - Infrapatellar bursitis: Presents with swelling and tenderness over the infrapatellar bursa, located just below the patella. It is often more distal compared to prepatellar bursitis. Prepatellar bursitis (Housemaid's knee): Typically seen in occupations involving prolonged upright kneeling, such as: Housemaids/cleaners Carpet layers Floor installers Roofers Infrapatellar bursitis (Clergyman's knee): Associated with jobs requiring kneeling on bent knees or frequent pressure below the patella, such as: Clergy (historically from prolonged kneeling during prayer) Plumbers Gardeners Tilers

102
When to DXA scan vs start bisphosphonate
Offer oral bisphosphonates to people taking glucocorticoid therapy without waiting for bone density assessment (which should follow later) if they have any of the following risk factors: A prior fragility fracture. Women age 70 years or over. Postmenopausal women, and men age 50 years or over taking high dose glucocorticoids (7.5 mg or more of prednisolone daily or equivalent over 3 months). Postmenopausal women, and men age 50 years or over with a FRAX probability of major osteoporotic fracture or of hip fracture exceeding the intervention threshold.

108
Differentiating Chondromalacia Patellae, Osgood-Schlatter Disease, and Osteochondritis Dissecans
Chondromalacia Patellae - Softening and degeneration of the articular cartilage on theurface of the patella. Presents with anterior knee pain exacerbated by activities that load the patellofemoral joint walking up/down stairs, rising from sitting. - No swelling or locking. - Tenderness is usually around the patella. Osgood-Schlatter Disease - Traction apophysitis of the tibial tubercle. - Repetitive strain from the patellar tendon pulling on the immature tibial tuberosity growth plate. Common in sporty adolescents (both sexes). - Localised pain, tenderness, and swelling over the tibial tubercle (apophysis). - Pain worsens with activities involving knee extension against resistance (running, jumping). Osteochondritis Dissecans - Localised subchondral bone necrosis due to repetitive microtrauma or vascular insufficiency. - Activity-related knee pain with intermittent swelling. - Mechanical symptoms such as locking or catching due to loose bodies

Which bones does osteosarcoma vs Ewing effect
Osteosarcoma- metaphysical regions of long bones especially around knee Ewing- diaphysis of long bones and pelvis
133
When to offer DEXA
Anyone >50 with a fragility fracture Anyone <40 with a major risk factor: Vertebral fracture High-dose corticosteroids (≥7.5mg prednisolone daily ≥3 months) ≥2 fragility fractures Calculate QFracture (preferred) or FRAX 10-year risk If high or borderline risk → proceed to DEXA
134
Pubic symphysis dysfunction
Commonly triggered by pregnancy Pain over pubic symphysis, radiates into the groins A ‘waddling’ gait
135
Meralgia paraesthetica.
Burning pain in the anterolateral thigh, worse on standing or walking and relieved by sitting, and pain reproduced by palpation over the ASIS
136
Mx of mechanical back pain
NSAIDs
137
Posterior knee dislocation- nerve affected and symptoms
Tibial nerve Motor: Plantarflexion + inversion Sensory: Sole of foot
138
Common perineal nerve injury mechanism and sx
Injury: Fibular neck compression Motor: Dorsiflexion + eversion (anterior + lateral compartments) Sensory: Dorsum of foot, lateral leg Features: High-stepping gait
139
Femoral nerve injury mechanism and sx
Roots: L2–L4 Motor: Anterior thigh → knee extension, hip flexion Sensory: Anterior + medial thigh, medial leg and foot Injury: Hip fracture, pelvic trauma
140
Obturator nerve injury mechanism and sx
Roots: L2–L4 Motor: Thigh adduction Sensory: Medial thigh Injury: Anterior hip dislocation
141
Sciatic nerve injury mechanism and sx
Roots: L4–S3 Motor: Posterior thigh (knee flexion), all leg and foot muscles Sensory: Posterior thigh, lateral leg, entire foot Injury: Posterior hip dislocation, acetabular fracture
142
Superior gluteal nerve injury mechanism and sx
Roots: L4–S1 Motor: Gluteus medius + minimus → hip abduction Sensory: None Injury: Pelvic surgery or fracture Sign: Positive Trendelenburg (pelvic drop on swing side when standing on affected leg)
143
Inferior gluteal nerve injury mechanism and sx
Roots: L5–S2 Motor: Gluteus maximus → hip extension Sensory: None Injury: Pelvic trauma/surgery
144
lower back with intermittent shooting pains down the front of his thigh. On examination power is 4/5 on knee extension, there is sensory impairment over the anterior thigh and loss of knee jerk reflex in the left leg.
Give NSAIDs First line for radiculopathy pain
145
Firm, fixed lump increasing in size in child ix
Very urgent US <48hrs for Ix of sarcoma
146
Ix of MSK cancers in children
Lump increasing in size → ultrasound within 48 hours Unexplained bone pain or swelling → X-ray within 48 hours Suspicious imaging → specialist referral within 48 hours
147
Breast cancer/myeloma and bone metastases mx
Bone-modifying agent (either zoledronic acid or denosumab) Consider in prostate cancer if other analgesia fails
148
Gonnorhoea septic arthritis mx
IV third-generation cephalosporin
149
Spinal fracture sx
Sudden onset, severe central back pain which is worse with loading (e.g. standing) Examination may reveal point vertebral tenderness.
150
Pain of OA from hip
Pain from hip OA is classically felt in the anterior groin, occasionally radiating to the thigh or knee, and worsens with activity but eases with rest. Loss of internal rotation (especially with hip flexion) is an early sign, and crepitus or stiffness may also be present.
151
Metastatic spinal disease presentation
Progressive, unremitting pain (especially at night)
152
MOA of tibial plateau fracture
struck on the knee by a car bumper Fall from height high-energy valgus/axial load causing a tibial plateau fracture.
153
Differentiating knee injuries
ACL tear: audible pop, rapid swelling (<2 hrs), positive Lachman test PCL tear: dashboard injury, posterior sag sign Meniscal tear: twisting + locking + joint line tenderness MCL injury: lateral trauma + medial pain + valgus test positive LCL injury: medial trauma + lateral pain + varus test positive Tendon rupture: Fall or sudden eccentric loading of the knee can't extend knee or perform straight leg raise Tibial plateau fracture: severe bruising, often in high-energy injury
154
Metastatic spinal cord compression mx
Bed rest, 16mg Dex + PPI, radiotherapy or surgery if appropriate
