Types of Anterior Dislocation
– See: Multidirectional Instability: – Radiographic Subtypes: – Subcoracoid – most common type of anterior dislocation – head of humerus is displaced anteriorly w/ respect to glenoid, & is inferior to coracoid process; – greater tuberosity is fixed on anterior glenoid rim; – neck … Read more
Type VI Plateau Frx
– Discussion: Tibial Plateau Frx Menu – bicondylar frx w/ distal oblique shaft frx; – these frx have bicondylar frx along w/ dissociation of diaphysis from metaphysis; – if the medial plateau fragment is intact, this frx can be treated with placement of a lateral plate and and Ex … Read more
Type V
– Discussion: – type V growth plate injuries are due to severe axial loading; – some or all of the physis is so severely compressed that growth potential is destroyed; – angulation and limb length inequality may be long term complications
Type IV (Medial) Tibial Plateau Fractures
– See: – Tibial Plateau Frx Menu: Bicondylar Fractures and Type V Frx, Type IV Fractures, Total Depression Fracture – Discussion: – frx of medial tibial plateau (see total depression frx): – carries worst prognosis of all tibial plateau fractures; – 2 subsets of injury: … Read more
Type-IV Intertrochanteric Fractures
– See: Unstable Intertrochanteric Fractures – Discussion: – consist of an intertrochanteric frx w/ a subtroch component; – constitutes 15% of intertroch frx; – Treatment Options: – sliding hip-screw or 2nd-generation locking nail may be used in rx of intertroch-subtroch frx that have femoral shaft extension; … Read more
Type III Tibial Plateau Frx
– See: Tibial Plateau Frx Menu, Local Compression Frx – Discussion: – involves central or peripheral depression of frx of lateral plateau w/o associated lateral wedge fracture; – it usually occurs from minimal impact on weak osteoporotic bone; – commonly affects older age groups (55-60 yrs) w/ marked osteoporosis; … Read more
Type III Supracondylar Frx
– Discussion: – posterior cortex is disrupted w/ no cortical contact; – distal fragment is displaced posteriorly and proximally (by pull of triceps); – w/ medial displacement, the medial periosteal hinge is intact; – w/ lateral displacement, the lateral periosteal hinge is intact; – Physical Exam: … Read more
Type III: Pilon Frx
– Discussion: – severe articular comminution and articular impaction frx; – reduce fibula then perform plate & lag screw fixation; – restores length of fractured distal tibia: – reduce articular surface – carried out & maintained by temporarily stabilizing it with K wires; … Read more
Type III Olecranon Frx
– Discussion: – frx is displaced & forearm is unstable in relation to humerus; – this injury is really a fracture-dislocation; – Avulsion Fracture – Comminuted Fractures – Distal Olecranon Fracture: … Read more
