Trauma of the Upper Limb Content • Clavicle Fractures • Shoulder Dislocations • Humerus Fractures • Fractures of the Forearm • Distal radius fractures
Clavicle Fractures • Mechanism • Fall onto shoulder (87%) • Direct blow (7%) • Fall onto outstretched hand (6%)
Classification • Type I Middle Third (80%) • Type II Distal Third (15%) • Type III Medial Third (5%)
Clinical Evaluations • Pain • Local deformity/abnormal motion • Radiography
Treatments • Conservative Treatment: Eight bandage immobilization for 4 weeks.
Treatments • Surgery • Fractures with neurovascular injury • Fractures with severe associated chest injuries • Open fractures • Cosmetic reasons, uncontrolled deformity • Nonunion
Shoulder Dislocations • Epidemiology • Anterior: Most common • Posterior: Uncommon, 10% • Inferior: Rare, hyperabduction injury
Evaluations • Clinical Evaluation • Lose of a round shape of the shoulder • Dysfunction • Dugas sign (+)
Evaluations • Radiographic Evaluation
Treatments • Closed Reduction • Hippocratic technique: effective for one person • Appropriate sedation
Post-reduction • Dugas sign (-) • Reduced local pain • Post X-ray films are a must to confirm reduction • Immobilization for 1-2 weeks before progressive ROM • Operative indications • Irreducible shoulder, failed due to soft tissue interposition • With fractures of the humeral head • Habitual dislocations
Proximal Humerus Fractures • Most common fracture of the humerus • Higher incidence in the elderly, thought to be related to osteoporosis • Females 2:1 greater incidence than males • Most commonly due to a fall onto an outstretched arm from standing height;
Proximal Humerus Fractures • Minimally displaced fractures- Sling immobilization, early motion • Complicated fractures: Open reduction and internal fixation (ORIF)
Humeral Shaft Fractures • Commonly resulted from indirect injury • Indirect injury results in Spiral or Oblique fractures • Complications : - Radial nerve injury - Delayed union & non-union
Clinical Evaluation • pain, swelling, deformity of the upper arm • Careful nerve exam is important as the radial nerve is in close proximity to the humerus and can be injured: wrist drop
Treatments • Closed reduction & immobilization with a splint or hanging cast . • Goal of treatment is to establish union with acceptable alignment • >90% of humeral shaft fractures heal with nonsurgical management
Treatments • Open reduction internal fixation by plate and screws or internal locking nail. • Indications: inadequate reduction, nonunion, associated injuries, open fractures, segmental fractures, associated vascular or nerve injuries
Supra-condylar Fracture of Humerus • More common in Children • Indirect injury
Typical treatment: Surgery K wires fixation
Fractures of the Forearm • Direct trauma or falling on the outstretched hand • Patients typically present with gross deformity of the forearm and with pain, swelling, and loss of function at the hand • Careful exam is essential, with specific assessment of radial, ulnar, and median nerves and radial and ulnar pulses • Tense compartments, unremitting pain, and pain with passive motion should raise suspicion for compartment syndrome
Monteggiafractures A fracture of the proximal ulna with an associated radial head dislocation
Distal radius fractures • One of the most common fractures in elderly; • Gross deformity of the wrist with variable displacement of the hand; • Most common: Colles fractures
Distal Radius Fractures • Colles’ Fracture : Fracture of the distal end of the radius, most common among elderly women, related to postmenopausal osteoporosis • Mechanism : Falling on outstretched hand, with wrist between 40-90 degrees of dorsiflexion • Pathological Anatomy : The distal fragment is displaced upwards, dorsally and laterally producing the classical dinner fork deformity
Radiographic Evaluation • Normal bony relationships of the wrist 11 Deg 23 Deg 11 mm
Treatment • Displaced fractures require and attempt at reduction. • Hematoma block-10ccs of lidocaine or a mix of lidocaine and marcaine in the fracture site • Reproduce the fracture mechanism and reduce the fracture • Place in cast
Manipulative reduction • Use the soft tissue hinge to reduce fracture
Operative Management • For the treatment of intraarticular, unstable, malreduced fractures.
Trauma of the Lower Limb Content • Hip Fractures / Dislocations • Femur Fractures • Patella Fractures • Tibia Fractures
Hip Dislocations • Significant trauma, usually MVA • Posterior: Hip flexion, inner rotation, adduct
Mechanism • Anterior: rare
Closed Reduction: Emergency • Emergency is necessary for reducing risk of DVT and AVN, under anesthesia • Need a team! • Allis Maneuver
After Reduction • Repeat AP pelvis film • No flexion >60 degrees • Early mobilization under aid • Follow the risk of avascular necrosis
Hip Neck Fractures • One of the most common fractures in the elderly • Female > male • May result from a simple fall • Intra-capsular fracture
Classifications • Garden Classification • I Valgus impacted • II Non-displaced • III Complete: Partially Displaced • IV Complete: Fully Displaced • Functional Classification • Stable (I/II) • Unstable (III/IV) I II III IV
Treatments • Non-operative • Very little role • Traction • Operative • ORIF (canulated screws or DHS) • Hemiarthroplasty (>65 years old) • Total Hip Replacement
Intertrochanteric Hip Fractures • Extra-capsular femoral fractures • To inferior border of the lesser trochanter
Treatments • Typically surgery: DHS, DCP, PFN
Femoral Shaft Fractures • Intra-madullary nail • ORIFwith plate and screws
Distal Femur Fractures • High energy, multiple trauma • High incidence of post-traumatic arthritis if the knee was disrupted
