ANATOMY The tooth is composed of three layers: enamel, dentin, 30 DENTAL and the pulp chamber (see Fig. Elizabeth M O’Connor, DDS Enamel protects the crown of the tooth because of its hardness and structure. INTRODUCTION There are many benefits to participating in athletic activities, such as enhanced physical fitness and the enjoyment from competition. Sport, however, also increases the risk of sustaining an injury, especially injuries to the teeth and mouth. EPIDEMIOLOGY An oral injury can be defined as dental avulsions, dental fractures, dental luxations, lacerations or con- tusions to the gum, cheeks, tongue, lips and jaw injuries (fracture, locked open or closed, temporo- mandibular joint pain, and chewing difficulty). A con- cussion from a blow under the chin can also be included (Kvittern et al, 1998). Pulpal involvement can be seen by than the enamel and has dentinal tubules that contain examining the fractured area and looking for a bleed- neurovascular structures.

What is the quality of your pain—sharp cheap 30 mg remeron amex, stabbing cheap remeron 15 mg with amex, numbness remeron 30 mg cheap, tin- gling generic 30mg remeron otc, etc buy remeron 30mg with mastercard.? Patients with numbness, tingling, and shooting electric pains in the ulnar nerve distribution are likely to have cubital tunnel syndrome or ulnar collateral ligament injury (ulnar nerve symptoms are often associated with ulnar collateral ligament injury). This question is specifically for rheumatoid arthritis—a disease characterized in part by its symmetric distribution of symptoms. Have you noticed any weight loss or systemic symptoms, such as flushing or fever? Patients with a loose body in their elbow from either a fracture or osteochondritis dissecans may complain of locking and/or clicking. This question is more useful for when you are ready to order diag- nostic studies and decide on treatment. Having completed the history portion of your examination, you have narrowed your differential diagnosis and are prepared to perform your physical exam. Patients with rheumatoid arthritis will have bilateral, symmetrical swelling. Palpate the joint as you move it passively through extension and flex- ion. Any crepitus may reflect underlying osteoarthritis or synovial or bursal thickening. There is a bursa in this location, and tenderness there indicates olecranon bursitis. Next, palpate the medial collateral ligament, which attaches from the medial epicondyle of the humerus to the coronoid process and the olecranon of the ulna. This ligament is responsible for the medial sta- bility of the elbow and is often injured in baseball pitchers because of the excessive valgus stresses placed on the ligament. Test for its stability by cup- ping the posterior aspect of the patient’s elbow with one hand, and holding the patient’s wrist with the other hand. Have the patient flex the elbow a few degrees and then apply a medially directed force to the patient’s arm while simultaneously applying a laterally directed force to the patient’s wrist. This maneuver places a valgus stress on the 42 Musculoskeletal Diagnosis Photo 2. With the hand cupped under the patient’s elbow, appreciate any medial gapping, which would indicate medial collateral ligament injury. Test the stability of the lateral collateral ligament by placing a varus stress on the forearm. Do this by placing a laterally directed force to the patient’s arm and a medially directed force to the patient’s wrist and note any gapping, which would indicate a lateral collateral ligament injury (Photo 2). Palpate the ulnar nerve as it runs in the groove between the medial epicondyle and the olecranon (Photo 3). The ulnar nerve feels round and tubular, and you can roll it between your fingers. However, because one- quarter of asymptomatic people will have a positive Tinel’s sign at this location, it is a very nonspecific test. If cubital tunnel syndrome is sus- pected based on the patient’s history, another test that may be performed is to maximally flex the patient’s elbow with the forearm supinated and wrist extended (Photo 4). When this position is held for 60 seconds and reproduces the patient’s elbow pain and radiation of symptoms into the fourth and fifth digits, it is considered a positive test for cubital tunnel syndrome. Another clinical sign for cubital tunnel syndrome is the Wartenberg sign. To elicit this sign, passively spread the patient’s fingers and instruct the patient to adduct the fingers. Weakness or atrophy in the fifth digit adductor is a positive Wartenberg sign. Start by palpating the lateral epi- condyle of the patient’s humerus for tenderness. To perform the Cozen test, the examiner stabilizes the patient’s elbow with one hand and the patient is instructed to make a fist, pronate the forearm, and radially deviate the wrist. Finally, the patient is instructed to extend the wrist against resistance that is pro- vided by the examiner (Photo 5).

This is know as the offset of the head [9, with complex mathematical calculations [3, 8, 13, 15, 22, 19, 21]. The author has developed a relatively simple method for determining the contact area between the acetabulum Calculation of loading and femoral head, subject to the requirement that the In a double-leg stance, only external forces act on the hip femoral head and acetabulum are roughly spherical and via the weight of the body.

The figures marked on the template also allow an estimate to be made of the angles between the center of the femo- ral head and the anterior and posterior acetabular rims. The two angles for the anterior and posterior sides are read off the template and then marked on the x-ray. The acetabular orientation in both the sagittal and anatomical planes can be determined by drawing a line between the two marks entered for the angles on the ventral and dorsal sides. The template can also be used to calculate the relevant loading of the hip. Example of a contact area calculation using a template placed on an AP x-ray of the hip.
