Orthopaedic deformities may result from abnormalities of bone, joints, growth plates, muscles, tendons, ligaments or nerves and can be angular, rotational, translational or length-related. Common deformities include cubitus varus and valgus...

Garden I–II = non-displaced, III–IV = displaced. Pauwels I 50° vertical shear. Young = urgent reduction + fixation (CS/DHS). Elderly = arthroplasty if displaced. Complica...
Indications: femoral shaft fractures, temporary stabilization. Provides traction + splintage. Structure: proximal ring, side bars, distal crossbar. Complications: sores,...
Used for tibia/femur fractures with traction. Has pulleys, slings; allows elevation and adjustment. Complications: sores, stiffness, peroneal palsy.
Non-invasive traction in children. Types: Gallows (
AFO: ankle-foot support in drop foot, CP, polio. KAFO: supports knee in quadriceps paralysis, SCI. Types: rigid, hinged, leaf-spring (AFO); locked, drop lock, offset (KAF...
Malunion = fracture healing in unacceptable position (angulation, rotation, shortening, translation). Nonunion = failure of fracture to heal in expected time (9 months wi...
Raised intracompartmental pressure → ischemia/necrosis. Causes: tibia/forearm fractures, crush injury, reperfusion, tight casts. Early signs: pain out of proportion, pain...
CT: excellent for cortical bone, 3D recon. MRI: excellent for marrow, soft tissue, ligaments, cartilage. CT indications: complex fractures (pelvis, acetabulum, calcaneus)...
Bone scan = radionuclide (Tc-99m MDP) uptake proportional to osteoblastic activity. Highly sensitive for metastasis, stress fractures, infection, AVN. PET (FDG-PET): meas...
ETC: definitive fixation within 24 h for stable patients. DCO: temporary stabilization in unstable patients; definitive fixation after stabilization. Second hit phenomeno...
Score based on skeletal/soft tissue injury, ischemia, shock, age. Ischemia >6 h doubles points. MESS ≥7 → amputation likely. Adjunct tool; not absolute.
Common alloys: 316L stainless, cobalt‑chrome, titanium (Ti‑6Al‑4V). Corrosion mechanisms: fretting at modular junctions, crevice under plates, galvanic with dissimilar me...
