Rectus sheath hematoma presents as a painful cheap vasotec 10mg without a prescription blood pressure zetia, tender mass in the caudal region of the rectus muscles buy vasotec 5 mg mastercard excel blood pressure chart. To ascertain whether the mass is intraabdominal or within the abdominal wall, the recumbent patient is asked to tense the abdominal wall musculature by raising the head. Although many rectus sheath hematomas are self-limiting and absorb spontaneously, those that are very large or expanding require surgical evacuation and hemostasis. Neurogenic pain can arise from radiculopathy affecting the anterior abdominal wall dermatomes, T7 to L1, due to compression of nerve roots by a disk tumor, infection, or hematoma. Herpes zoster, varicel- lar viral nerve infection, occurs frequently in older adults and immuno- suppressed patients, producing severe burning pain in a dermatomal distribution. Painful peripheral nerve entrapment can complicate abdominal hernias and surgical scars. The diagnosis is made by extin- guishing the typical burning pain by injection of a local anesthetic into the trigger zone. Abdominal epilepsy and syphilitic tabes dorsalis are rare central nervous system causes of abdominal pain. Anatomic structures adjacent to the abdominal cavity may refer pain that is misinterpreted as intraabdominal in origin. Thoracic pain from basilar pleuritis or pericarditis due to pneumonia, pulmonary, or myocardial infarction may mimic subdiaphragmatic pathology. Con- versely, subdiaphragmatic pathology, such as gastroesophageal reflux and choledochal disease, may suggest myocardial ischemia and other intrathoracic disorders. A classic example of distal referral from an abdominal pain source is pain felt at the root of the ipsilateral neck due to diaphragmatic irritation. This occurs because the phrenic nerve con- tains nerve fibers from the cervical 3 and 4 roots that also innervate the neck. In the lower abdomen, extraperitoneal pelvic and perineal pathol- ogy may masquerade as intraperitoneal disease. Clinical awareness of these diagnostic pitfalls and appropriate imaging studies usually lead to the correct diagnostic conclusions and avoidance of nonindicated surgery. Abdominal Pain 407 Summary The list of disease processes that cause abdominal pain is extensive. Most of these maladies never require surgery; however, recognizing when emergent, urgent, or elective operative intervention is required is a necessary skill for general surgeons and most physicians. Starting with a directed history of the nature of the pain and the associated symptoms, one can begin to formulate a differential diagnosis. The past medical and surgical history often provides additional clues as well as a picture of the patient’s overall condition. Understanding that the rigid abdomen seen with free air and the involuntary guarding seen with peritoneal irritation are signs of surgi- cal emergencies is the first step. Further refinement of diagnostic skills comes with the number of abdominal exams one performs. The history and physical combined with laboratory and imaging studies usually provide enough information to determine if the patient has a cata- strophic abdominal emergency, an urgent surgical condition, an elec- tive surgical condition, or a nonsurgical condition.

These four muscles form a conjoined tendinous cuff that attaches to the proximal humerus purchase vasotec 5 mg useless eaters hypertension zip. Rotator cuff muscles take their origin from the scapula and essentially pull the humeral head into the glenoid cheap vasotec 10mg with amex arterial blood gases. Rotator cuff strains can occur as a result of lifting relatively light as well as heavy objects. Repetitive use of the upper extremity also can lead to inflammation of the rotator cuff. In these cases, patients will note pain with forward elevation or abduction of the upper arm. Most strains and tendinopa- thy resolve with antiinflammatories and rehabilitative exercises. In some cases, the rotator cuff can tear away from the attachment on the proximal humerus. In these cases, patients notice pain and weak- ness with forward elevation and abduction of the shoulder. Small tears of the rotator cuff can be managed conservatively, using nonsteroidal antiinflammatory drugs and rehabilitative exercises. The usual treatment involves removal of the anterior portion of the acromion, release of the coracoacromial ligament, and repair of the torn rotator cuff to its humeral attachment. As stated earlier, the glenohumeral joint does not have tremendous osseous stability. Consequently, the glenohumeral capsule and liga- ments provide an important role as static stabilizers to the gleno- humeral joint. Dislocation of the glenohumeral joint usually results in detachment of the capsule and ligaments from the rim of the glenoid. In the most common dislocation, the humeral head dislocates in an anterior and inferior direction in relation to the glenoid face. However, isolated inferior dislocations and posterior dislocations of the glenohumeral joint also occur. Inferior glenohumeral dislocations are referred to as luxatio erecta, and the patient presents with the arm fully abducted. Posterior glenohumeral dislocations usually result from a seizure, an electrical shock, or a fall onto the anterior aspect of the shoulder. Anterior dislocations of the glenohumeral joint are signifi- cantly more common than the other two types (Fig. These usually occur as a result of trauma to the shoulder while the arm is held in an abducted and externally rotated position or as a result of a direct blow to the posterior aspect of the shoulder. When evaluating a patient with a shoulder dislocation, the axillary nerve function should be evaluated prior to reduction, since this can be injured at the time of the dislocation. Injury to the axillary nerve would result in decreased sensation near the distal insertion of the deltoid muscle as well as diminished deltoid function. In the elderly population, recurrence of glenohumeral dislocation is quite rare, although attention should be paid to the function of the rotator cuff during early recovery after the dislocation. If there is evidence of rotator cuff tear early after a glenohumeral dislocation, consideration should be given to surgical repair. In the younger, more athletic popu- lation, glenohumeral dislocation frequently can lead to glenohumeral Figure 33. The risk of redislocation of the glenohumeral joint after a primary traumatic dislocation ranges from 70% to 90%. The subse- quent dislocations usually require less trauma than the index disloca- tion. In many cases, recurrent instability of glenohumeral joint requires surgical intervention. The treatment usually consists of repairing the anterior inferior capsule and the inferior glenohumeral ligament complex to the rim of the glenoid. This occurs when patients fall on the lateral side of their upper arm or run into a hard object, such as an outfield wall in baseball. However, the clavicle is fixed rigidly by the sternoclavicular joint and really does not rotate significantly. However, in more significant injuries, dis- ruption of the ligaments is accompanied by penetration of the delto- trapezial fascia by the distal clavicle. In this case, the distal clavicle is in a subcutaneous position and will lead to chronic pain.
