3 Sensitivity Ability to identify patients with particular disorder Ability to correctly identify positives SnNout: Sensitivity Negative rules Out If test is (-), low probability of having disorder Specificity Ability to identify patient without particular disorder Ability to correctly identify negatives SpPin: Specificity Positive rules In If test is (+), high probability of having disorder
4 Condition (Gold standard result) Positive Negative Test Outcome Positive True Positive False Positive Negative False Negative True Negative PPV NPV Sensitivity Specificity
5 Predictive Value Positive: proportion of patients with positive diagnoses that truly have the disorder Negative: proportion of patients with negative diagnosis that truly do not have the disorder
6 Likelihood Ratio Positive: probability shift to the patient does have the disorder Negative: probability shift to the patient does not have the disorder (+) LR (-) LR Interpretation of probability shifts >10 <0.1 Large & often conclusive shifts Moderate shifts Small but sometimes important shifts Small & rarely important shifts
7 The Musculoskeletal System System is comprised of 206 bones that provide the framework for the body and protect various organs Also includes soft tissue, which includes cartilage, tendons, ligaments and muscles
8 Musculoskeletal Overview Bones, cartilage, tendons, and ligaments are all connective tissue consisting of living cells, non living protein fibers and an amorphous ground substance
9 Other things that make up the Musculoskeletal System Tendons connect muscle to bone have good blood supply and heal well Ligaments- connect bone to bone, indirect blood supply and have a longer healing time Both of these have great tensile strength Joints-union of two or more bones Bursae-cushion of joints
10 Other Components Bursae: located between bones, tendons and ligaments that move against each one another, prevents friction Menisci: fibrocartilage structures of crescent shape that are thought to be formed in fetal development
11 Types of Joint Movement Flexion: bending of joints that decrease angle between 2 bones Extension: bending of joint that increases angle between two bones Hyperextension: extension in which the angle exceeds 180 degrees Dorsiflexion: movement of the body part up toward the dorsum Plantarflexion: flexion of the ankle down toward the ground Abduction: movement of part away from midline Adduction: movement of part toward midline Pronation: turning downward Supination: turning upward Circumduction: combinations of flexion, extension, abduction and adduction resulting in circular motion of the body part
12 History/Interview The medical interview or consultation influences the precision of diagnosis and treatment, and studies have indicated that over 80% of diagnoses in general medical clinics are based on the medical history Physicians themselves have contributed to a culture of medical practice in which objective test results are given more credence and are felt to be more reliable than the subjective story of the patient or assessment of the physicians J Gen Intern Med January; 14(S1): S26 S33.
13 5 Minute Consultation. Less time, otherwise, will mean less relating time and damage to care: less-accurate and incomplete data; difficulty in identifying the real problems; less efficiency in test and treatment choices based on knowledge of the individual patient; less trust; less healing; more errors and more waste Tamblyn R, Berkson L, Dauphinee WD, Gayton D, Grad R, Huang A, Isaac L, McLeod P, Snell L Ann Intern Med Sep 15; 127(6):
14 Listen Listen to the patient s answer without interrupting. Studies show that clinicians interrupt patients during office visits after only 18 seconds! If patients are allowed to tell their stories, most will finish within 2 minutes Beckman HB, Frankel RM. The effect of physician behavior on the collection of data. Ann Intern Med 101(5): ,1984
15 B A T E S G U I D E T O P H Y S I C A L E X A M I N A T I O N A N D H I S T O R Y T A K I N G History/Patient Interview The Seven Attributes of a Symptom ATTRIBUTES OF A SYMPTOM 1. Location. Where is it? Does it radiate? 2. Quality. What is it like? 3. Quantity or severity. How bad is it? (For pain, ask for a rating on a scale of 1 to 10.) 4. Timing. When did (does) it start? How long does it last? How often does it come? 5. Setting in which it occurs. Include environmental factors, personal activities, emotional reactions, or other circumstances that may have contributed to the illness. 6. Remitting or exacerbating factors. Is there anything that makes it better or worse? 7. Associated manifestations. Have you noticed anything else that accompanies it?
16 EXPLORING THE PATIENT S PERSPECTIVE The patient s thoughts about the nature and the cause of the problem The patient s feelings, especially fears, about the problem The patient s expectations of the clinician and health care The effect of the problem on the patient s life Prior personal or family experiences that are similar Therapeutic approaches the patient has already tried
17 Conclusion of Interview Summarization Giving a capsule summary of the patient s story during the course of the interview can serve several different functions. It indicates to the patient that you have been listening carefully. It can also identify what you know and what you don t know. Anything else?
18 Mechanism of Injury Was there an injury? Describe the mechanism? Immediate swelling? Care provided prior to presentation to clinic? Ice, heat, OTC or prescriptions taken Prior injuries? Prior treatment? If no injury?
19 Perils of Orthopedics Explain what you are going to be doing. Always examine the normal extremity first Establishes rapport/familiarity with patient Gives examiner a baseline for normal ROM Flexibility Strength Joint Laxity Bony Landmarks DON T JUST PALPATE or Poke

21 Ankle Anatomy
22 Ligaments and attachments
23 Muscles and Tendons
24 Squeeze Test To perform the squeeze test, compress the midleg from posterior lateral to anterior medial. The squeeze test is used to identify disruption of the tibiofibular syndesmosis (the interosseus membrane between the tibia and fibula).
25 Talar Tilt Perform the talar tilt test with the ankle in both the neutral position (A) and in plantar flexion (B). With the patient seated, secure the lower leg with one hand and grasp the forefoot with the opposite hand. Apply an inversion force to produce a talar tilt
26 Anterior Drawer The anterior drawer test also assesses the integrity of the ATFL. While the patient is seated, grasp the lower leg with one hand and the forefoot with the other. Then, apply an anterior force to produce forward translation rqok1ak&feature=relmfu
27 Achilles Tendon Rupture/
28 Ottawa Ankle Rules Ankle radiographs are indicated if there is pain in the malleolar region and any of the following: 1. Tenderness of posterior edge of distal 6 cm or tip of lateral malleolus, or 2. Tenderness of posterior edge of distal 6 cm or tip of medial malleolus, or 3. Unable to bear weight (4 steps) both immediately after the injury and at the time of evaluation
29 Ottawa Ankle Rules Foot radiographs are indicated if there is pain in the midfoot region and any of the following: 1. Tenderness of the navicular bone 2. Tenderness at the base of the 5 th metatarsal 3. Unable to bear weight (4 steps) both immediately after the injury and at the time of evaluation

35 The Ottawa knee rules are a set of rules used to help physicians determine whether an x-ray of the knee is needed.  They state that an x-ray is required only in patients who have an acute knee injury with one or more of the following: Age 55 years or older Tenderness at head of fibula Isolated tenderness of patella Inability to flex to 90 Inability to bear weight both immediately and in the emergency department (4 steps
