  1. Department of Orthopaedic Surgery and Rehabilitation UNMC Orthopaedic Surgery Welcome to your M4 Clerkship and Welcome to Omaha

  2. Introduction • Welcome • Expectations and goals • General considerations for Orthopaedic history and physical exam • Introduction to reading x-rays • Trauma/Open Fractures • Compartment Syndrome

  3. WELCOME • Welcome to UNMC and your Orthopaedic clerkship • We are here to teach you the basic foundations of Orthopaedics. • With that, you should be able to gain a feel for what a career in Orthopaedics may be like. • We are happy to have you as a part of our team for the next month and hope you gain a lot of useful information while you are here

  4. Expectations: General • Show up on time, be available, and work hard • Read before surgical cases (anatomy and surgical plan) • Be helpful, be inquisitive, ask questions • Learn basic management of common musculoskeletal problems • Participate actively in rounds, clinics, conference, and general discussions about Orthopaedic problems

  5. Expectations Cont. • Be able to access knowledge about Orthopaedics from books, internet, journals, etc.. • Be able to answer questions about musculoskeletal anatomy, common injuries, treaments, etc.. Especiallywhen asked to look it up beforehand.

  6. Clinical functioning at the level of an intern • Think about the patient care plan: • Pre-op planning • Medical workup before surgery • Antibiotics • Pain control • DVT prophylaxis • Therapy goals & restrictions • Dressing changes / drain output • Discharge planning & clinic follow-up • Read other consult service notes for their plan

  7. Goals • At the end of your rotation you should be able to: • Read basic x-rays appropriately • Perform an orthopaedic history and physical • Recognize common fractures, their classification, and know how to acutely manage them • Understand basic patient care for the Orthopaedic patient • Be able to diagnose common musculoskeletal problems

  8. CALL

  9. Divide call on trauma nights between the students such that you average no more frequently than q4 during your month. • Be sure to get at least one full weekend off. We’d like you to be able to both have a life and also get to know a little about our city. • The actual schedule is left up to the students to arrange. Be fair to each other.

  10. Carry the on-call pager and notify the junior resident on-call that you will be taking call with them that evening • The best opportunity to learn how to suture, splint, cast, and possibly do reductions as a medical student takes place on-call and in the ER/trauma bay.

  11. CONFERENCES

  12. Conference Schedules • Three rules • If there is an assigned reading for a conference, be sure to get a copy and read it. • No scrubs in conference, dress appropriately. • Be on time. Tardiness to conference will be looked upon very poorly.

  15. Orthopaedic History • A good general orthopaedic history contains: • Onset, Duration, and Location of a problem • Limitations and debilitation attributed to the problem • Good surgical history, especially with regards to orthopaedic surgeries and prior anesthesia • Co-morbid conditions that contribute to the problem or will preclude healing in some manner

  16. Physical Exam Basics • Inspect and Palpate everything- start with normal structures and move to abnormal • Range of motion in all planes • Strength • Sensation • Reflexes • Gait • Stability

  17. Physical Exam Basics • NVI What does this mean? • Neurologic exam- Always document the neurologic status. Some fractures are associated with nerve injuries and knowing the status of the nerve is critical • Vascular exam- Always check for pulses distal to the fracture sight. Missed vascular injuries can be devastating

  18. Physical Exam • NEVER trust someone else’s exam. ALWAYS put your hands on the patient and see for yourself • Always trust your exam- you WILL pick up something that someone else has missed at some point

  19. Imaging

  20. Intro to Reading X-rays • Reading a radiograph is essentially describing the anatomy of a certain structure • In order for it to be universal and understandable for others, clarity and precision are essential • A fracture is described based on the findings of the physical exam and a review of radiographs

  21. Reading X-rays • Say what it is- what anatomic structure are you looking at and how many different views are there • Condition of the soft tissue- Open vs Closed • Regional Location- Diaphysis (rule of 1/3), Metaphysis, Epiphysis including intra and extra-articular, and Physis (pedi) • Direction of the fracture line- Transverse, Oblique, Spiral

  22. Reading X-rays • Condition of the bone- comminution (3 or more parts), Segmental (middle fragment), Butterfly segment, incomplete, avulsion, stress, impacted • Deformity-Displacemtent (distal with respect to proximal), angulation (varus, valgus), rotation, shortening (in cm’s), distraction

  23. Fracture Pattern • Transverse • Produced by a distracting or tensile force

  24. Fracture Pattern • Spiral • Produced by a torsional force

  25. Fracture Pattern • Butterfly • Produced by pure bending force

  26. Fracture Pattern • Comminuted • Broken into many pieces- high energy with combined forces

  27. Displacement • Characterized by % of bone contact on either view

  28. Angulation • Distal fragment relative to proximal • Varus, Valgus, Anterior, Posterior • Apex of angle formed by fragments • E.g., Apex Anterior, Apex Medial, Apex Ulnar

  29. Location • Commonly described in thirds of affected bone • ie distal third of tibia • ie junction of proximal and middle third of femur • If fractured at two levels describe as segmental

  30. Location-Diaphysis • Shaft portion of bone

  31. Location-Metaphysis • The ends of the bone (if the fracture goes into a joint it is described as intra- articular)

  32. Now All Together • Transverse fracture of the femur at the middle third- distal third junction with 100% displacement and varus (or apex lateral) angulation

  36. Casting, Splinting, and Definitive Fracture Fixaiton

  37. Definitive Fracture Fixation Options • Casts and Splints • Appropriate for many fractures especially hand and foot fractures • Adults typically will get plaster splints initially transitioned to fiberglass casts as swelling decreases • Kids typically will get fiberglass casts

  38. Definitive Fracture Fixation • Delayed until patient is stable (may be days or weeks) • Femur Fracture has priority as delay in fixation has negative impact on pulmonary status by shower of fat emboli to the lungs • Goals is to stabilize skeleton to allow patient to rapidly mobilize from bed

  39. Definitive Fracture Fixation Options • Traction • Useful in patients who are too sick for surgery • Useful to maintain alignment until definitive fixation

  40. Definitive Fracture Fixation Options • External Fixation • Used primarily in the treatment of open fractures and pelvis fractures • Also useful as temporary stabilization prior to definitive fixation

  41. Indications- Emergent Stabilization

  42. Definitive Fracture Fixation Options • Open Reduction and Internal fixation with Plates and screws • Used for many fractures especially those involving joints

  43. Definitive Fracture Fixation Options • Intramedullary Nails • Treatment of choice for most tibia and femur fractures • Used in selected humerus and forearm fractures

  44. Definitive Fracture Fixation Options • Joint Replacement • Used in displaced femoral neck fractures in geriatric patients • Allows for early ambulation • Occasionally used in geriatric pts with comminuted shoulder or elbow fractures

  45. Open Fractures

  46. Open Fractures • Open fractures refer to osseous disruption in which a break in the skin soft tissue communicates directly with a fracture • Any wound occurring on the same limb as a fracture must be suspected to be an open fracture until proven otherwise • A missed open fracture can have dire consequences

  47. Evaluation of open fractures • ABC’s • Identify the injured area • Assess neurovascular status of the limb both proximal and distal to the wound. Always use the normal side as a control • Assess skin and soft tissue damage. Exploration of a wound is not usually indicated in a trauma or emergency setting. If you know its an open fracture, splint it and prepare to go to the OR • DO NOT remove bone no matter how small or insignificant a piece it may seem • Always consider vascular injuries and compartment syndrome with open fractures

  48. Classification of open fractures • Gustillo Classification • Grade I- Clean skin opening of less than 1 cm, usually inside to out • Grade II- Open between 1 and 10 cm, extensive soft tissue injury, minimal to moderate crushing • Grade III- Open more than 10cm, extensive tissue including muscle damage, high energy • IIIA- Laceration with adequate bone coverage, segmental features, gunshot injuries • IIIB- Soft tissue injury with periosteal stripping, usually associated with massive contamination • IIIC- Any of the above with an associated vascular injury

  49. Acute Management of open fractures • Address hemorrhage with direct pressure • Initiate antibiotics • Grade I and II- Ancef 1g-2g IV • Grade III- Ancef plus Gentamicin 2mg/kg IV • Farm injuries or gross contamination- add Penicillin • Apply saline soaked gauze dressing to wound • Attempt reduction and apply splint • Operate- most surgeons use 8 hrs as the window for decreasing the incidence of infection and other related complications of open fractures
