Acute flexor carpi radialis tendinitis has been seen in clinical practice with increasing frequency due to the increasing popularity of both racquet sports such as tennis and golf order toprol xl online. Improper stretching of flexor carpi radialis muscle and flexor carpi radialis tendon before exercise has also been implicated in the development of flexor carpi radialis tendinitis as well as acute tendon rupture buy 50mg toprol xl fast delivery. Injuries ranging from partial to complete tears of the tendon can occur when the distal tendon sustains direct trauma while it is fully flexed under load or when the wrist is forcibly flexed while the hand is full ulnar deviation purchase 100 mg toprol xl overnight delivery. The pain of flexor carpi radialis tendinitis is constant and severe and is localized to the dorsoradial aspect of the wrist. The patient suffering from flexor carpi radialis tendinitis often complains of sleep disturbance due to pain. Patients with flexor carpi radialis tendinitis exhibit pain with active resisted flexion of the hand and with ulnar deviation of the wrist. In an effort to decrease pain, patients suffering from flexor carpi radialis tendinitis often splint the inflamed tendon by limiting hand flexion and ulnar deviation of the wrist to remove tension from the inflamed tendon. If untreated, patients suffering from flexor carpi radialis tendinitis may experience difficulty in performing any task that requires flexion and abduction of the wrist and hand such as using a hammer. Over time, if the tendinitis is not treated, muscle atrophy and calcific tendinitis may result, or the distal musculotendinous unit may suddenly rupture. Patients who experience complete rupture of the flexor carpi radialis tendon will not be able to fully and forcefully flex the hand or fully abduct the wrist. Plain radiographs are indicated in all patients who present with wrist and hand pain. Magnetic resonance imaging or ultrasound imaging of the wrist and hand is indicated if flexor carpi radialis tendinopathy or tear is suspected (Fig. Magnetic resonance imaging or ultrasound evaluation of the affected area may also help delineate the presence of calcific tendinitis or other hand pathology. A: Longitudinal sonogram of the right flexor carpi radialis muscle 16 days after initial symptoms shows discontinuity of muscle fibers and a 1. Sonographic appearance of nontraumatic tear of flexor carpi radialis muscle: a case report. With the patient in the above position, the distal crease of the wrist is identified and the patient is asked to forcibly flex his or her hand against resistance (Fig. The tendon of the flexor carpi radialis tendon will be evident closest to the thumb. A high-frequency linear ultrasound transducer is placed in a transverse position over the tendon and an ultrasound survey scan is taken (Fig. The tendon should appear just radial to the median nerve which appears as a bundle of hyperechoic nerve fibers surrounded by a slightly more hyperechoic neural sheath lying beneath the flexor retinaculum (Fig. The median nerve can be distinguished from the flexor tendons by simply having the patient flex and extend their fingers and observing the movement for the tendons. The flexor tendons will also exhibit the property of anisotropy with the tipping of the ultrasound transducer back and forth over the tendons. The flexor carpi radialis will be the most radial and superficial of the superficial flexor tendons. There may be significant effusion surrounding the tendon which will appear on transverse ultrasound imaging as a hypoechoic ring around the tendon. If there is a question as to whether the tendon is the flexor carpi radialis tendon, the ultrasound transducer can be turned to the longitudinal plane and the tendon can be followed distally to its insertion on the trapezium (Fig. After the musculotendinous unit is identified as it passes under the flexor retinaculum, it is evaluated for presence of tendinopathy, tendinitis, tears, infection, and extrinsic compression (Figs. A: Identification of the flexor carpi radialis tendon is facilitated by having the patient forcibly flex his or her wrist.

Note the significant amount of fluid surrounding the tendon and positive halo sign. Repeated injection of the flexor carpi radialis musculotendinous unit with steroids, the use of quinolones, and the use of anabolic steroids have been associated with rupture of the tendon at the wrist as it passes beneath the flexor retinaculum. Flexor carpi radialis tendinitis caused by malunited trapezial ridge fracture in a professional baseball player. The flexor carpi ulnaris muscle has two heads which find their origin on the medial epicondyle of the humerus and the medial margin of the olecranon process of the ulna. The muscle finds its insertion on the pisiform bone with a secondary insertion via ligaments to the hamate, the third and fifth metacarpals, and the tuberosity of the trapezium (Fig. The flexor carpi ulnaris muscle is innervated by the median nerve and receives its blood supply from the ulnar artery. It is at its point of insertion and at the point at which the distal flexor carpi ulnaris musculotendinous unit passes beneath the flexor retinaculum that it is susceptible to the development of tendinitis, tears, and rupture. The anatomy of the flexor carpi ulnaris muscle and its distal tendinous insertion. The relatively poor blood supply of the distal musculotendinous unit limits the ability of the muscle and tendon to heal when traumatized. Over time, muscle tears and tendinopathy develop, further weakening the musculotendinous unit and making it susceptible to additional damage and ultimately complete rupture. The flexor carpi ulnaris tendon of the hand may develop tendinitis after overuse or misuse, especially when performing activities that require repeated flexion and adduction of the hand.
The underlying pleura and lung are evaluated for effusion order toprol xl with amex, empyema order toprol xl from india, pleural thickening safe toprol xl 50 mg, pneumothorax, and pulmonary infarction (Fig. A low-frequency curvilinear transducer may provide superior imaging of the underlying lung if lung pathology is suspected (Fig. Longitudinal placement of the ultrasound transducer at the posterior angle of the ribs with the superior aspect of the transducer rotated approximately 15 degrees.

Real-time lung ultrasound for the diagnosis of alveolar consolidation and interstitial syndrome in the emergency department. The proximity to the pleural space to the rib and intercostal neurovascular bundle makes the potential for pneumothorax an ever present possibility in the presence of chest wall penetrating injuries and trauma or if the patient is undergoing interventional procedures such as intercostal nerve block and pleural biopsy. Should a pneumothorax occur, the “waves on a sandy beach” appearance of the normal pleural lung interface will be replaced with a more chaotic “ripples on a pond” appearance. Ultrasound-guided intercostal nerve block for traumatic pneumothorax requiring tube thoracostomy. Between the two pleurae lies the pleural cavity which contains a small amount of pleural fluid which facilitates this sliding function. The pleural fluid also helps maintain surface tension adequate to allow the visceral pleural to adhere closely to the parietal pleural thus optimizing expansion of the lungs. The outer parietal pleura is tightly attached to the chest wall, while the inner visceral pleura covers the lungs and adjacent structures. The parietal pleura is highly sensitive to pain with its costal and cervical surfaces as well as the outer diaphragmatic surfaces innervated by the intercostal nerves. The more central diaphragmatic and mediastinal surfaces of the parietal pleura are innervated by the phrenic nerve (Fig. The visceral pleura receives no somatic sensory innervation, but is innervated by the autonomic nervous system. The blood supply of the parietal pleura is from the intercostal arteries, with the visceral pleura receiving its blood supply directly from bronchial circulation. Contraction of the external intercostal muscles and the hemidiaphragms causes expansion of the chest wall resulting in an increased lung volume. This increased lung volume creates a negative pressure within the airways causing inspiration to occur. During periods of heavy respiration, the sternocleidomastoid and scalene muscles may serve as accessory respiratory muscles. The outer parietal pleura and inner pleura work together to help decrease the effort of breathing by allowing the two layers of pleura to slide against each other. The outer visceral pleura is tightly attached to the chest wall, while the inner visceral pleura covers the lungs and adjacent structures. The parietal pleura is highly sensitive to pain with its costal and cervical surfaces as well as the outer diaphragmatic surfaces innervated by the intercostal nerves. The more central diaphragmatic and mediastinal surfaces of the parietal pleura are innervated by the phrenic nerve. The visceral pleura receives no somatic sensory innervation, but is innervated by the autonomic nervous system. Inspection of the patient for the presence of cyanosis, tachypnea, the use of accessory muscles of respiration, retraction of the intercostal muscles, abnormal respiratory patterns such as Kussmaul and Cheyne–Stokes breathing, clubbing of the fingers, and pursed lip breathing is carried out. The jugular venous pressure is noted and the chest wall is inspected for symmetrical excursion, anatomic 639 abnormalities such as pectus recurvatum and carinatum, chest wall defects, paradoxical movement of chest wall segments as seen in flail chest, and the presence of barrel chest associated with chronic obstructive pulmonary disease (Fig. The posterior chest wall and spine are inspected for the presence of kyphosis or scoliosis that may compromise respiration. Computed tomography scan showing compression of the right cardiac chamber and displacement of the heart in a patient with scoliosis and severe pectus excavatum deformity. Modified nuss procedure in concurrent repair of pectus excavatum and open heart surgery. Palpation of both lung fields to identify consolidation associated with pneumonia is performed by placing both palms against the left and right posterior chest wall and feeling the vibrations transmitted as the patient counts from 1 to 10. The examiner then places the ulnar aspect of the hands on the left and right posterior chest wall while the patient repeated the words toy boat to identify asymmetry in sound transmission with increased vibrations associated with consolidation and decreased vibrations associated with pneumothorax. Percussion of the left and right anterior and posterior chest is then performed to identify asymmetry of sound. Pneumothorax will result in a tympanic sound and areas of pleural effusion and consolidation will yield a more dampened sound. Auscultation is carried out with the stethoscope and the respiratory sounds are assessed by comparing the left and right lung fields. Abnormal sounds such as rales, rhonchi, wheezes, crackles, whistles, stridor, and friction rubs are identified. Transmitted voice sounds are then assessed via auscultation by having the patient whisper the words blue balloons while looking for increase or decrease in the volume of the words heard by the examiner through the stethoscope. The whispered words will be louder in areas of consolidation and tumor and softer in areas of pneumothorax. Evaluation of all pathologic conditions of the pleura and lungs, and to a lesser extend the subcutaneous tissues and muscles overlying the pleura, begin with the ability to identify the rib, pleura, and lung. The rib will be identified as a hyperechoic curvilinear line with an acoustic shadow beneath it. The three layers of intercostal muscle, the external, internal, and innermost, will be identified in the intercostal space between the adjacent ribs (Fig. Color Doppler will help identify beneath the adjacent intercostal artery and vein (Fig. This space between adjacent ribs provides an excellent acoustic window which allows easy identification of the intercostal space and the pleura beneath it.
