Stress fracture of the first rib from serratus anterior tension: an unusual mechanism of injury.

Fracture of the first rib usually results from high-impact, direct trauma. Stress fractures are less common and are associated with minimal morbidity. The case of a patient with a stress fracture resulting from the use of an exercise machine is reported. Previous reports have attributed stress and fatigue fractures of the first rib to the forces exerted by the scalene muscles. A new pathophysiologic mechanism involving the serratus anterior muscle is introduced and is supported by T2 relaxation times from magnetic resonance imaging. Stress and fatigue fractures of the first rib have minimal complications. An aggressive diagnostic evaluation of first rib fractures occurring by this mechanism is not warranted.

Complications of shoulder dislocation.

Dislocations of the shoulder are the most common joint dislocations seen in the emergency department, and complications of shoulder dislocations are more frequent than is generally believed. It is vital that emergency physicians have current knowledge of complications associated with shoulder dislocations because of their important role in recognition and prevention. Delayed recognition of complications can have an impact on the long-term outcome of patients. Prompt recognition and follow-up are essential. Most references address reduction methods rather than recognition of specific complications. Emergency physicians have few opportunities to update their knowledge of complications of shoulder dislocations. This article briefly reviews mechanisms of shoulder dislocation and discusses complications in light of the mechanisms of injury.

Vanishing distal clavicle after arthroscopic acromioplasty.

Arthroscopic subacromial decompression is gaining wide acceptance. There are several reports on its technique, its limitations, and its efficacy. However, papers describing complications are rare. We describe a case of osteolysis of the distal clavicle after overenthusiastic arthroscopic subacromial decompression.

[Fulminant air embolism in arthroscopy of the shoulder joint using CO2].

We report on a case of an unexpected gas embolism during an arthroscopy of a newly injured shoulder joint. We used carbon dioxide as an arthroscopic medium which has not been considered hazardous up to now. The sudden decrease of the endtidal CO2 concentration in connection with a decrease of peripheral oxygen saturation as well as the clinical symptoms led to an immediate diagnosis of gas embolism. In this case external cardiac massage and aspiration of gas from the right ventricle proved an effective treatment.

[The value of sonographic diagnosis for the demonstration of Hill-Sachs lesions].

UNLABELLED: In a prospective study we evaluated the use of diagnostic ultrasound for Hill-Sachs lesions in unstable shoulder joints of 114 patients. In 38 patients we found a Hill-Sachs lesion by sonography. 31 patients underwent an arthroscopic procedure. The arthroscopic control of the sonographic findings showed a sensitivity of 95%, a specifity of 92%, an accuracy of 94%, a positive predictive value of 95%, and a negative predictive value of 92%. We also documented posttraumatic joint effusion. With these results ultrasound seems to be more reliable than x ray in the diagnosis of Hill-Sachs lesions. CLINICAL RELEVANCE: With a high diagnostic value for detecting Hill-Sachs lesions ultrasound may replace difficult special x ray techniques.

[Value of conventional x-ray diagnosis and computerized tomography in the detection of Hill-Sachs defects and bony Bankart lesions in recurrent shoulder dislocations].

Forty patients with anterior dislocation of the shoulder were examined in order to demonstrate Hill-Sachs defects and bony Bankart lesions. All patients had conventional radiographs of the shoulder in two planes, special views according to Hermodsson and Bernageau and CT. The examinations were evaluated by three observers. CT was regarded as the gold standard. Sensitivity for demonstrating Hill-Sachs defects for the standard views was 45% and for the Hermodsson views was 76%. For demonstrating Bankart lesions, standard views had a sensitivity of 37% and the Bernageau view 64%. Computed tomography was markedly superior to the standard and the special views, both for demonstrating the lesions and the agreement between various observers.

Unsolicited paresthesias with nerve stimulator: case reports of four patients.

IMPLICATIONS: Unsolicited paresthesias may occur when a nerve stimulator is used and may indicate valid proximity to the nerve. This phenomenon suggests that nerve stimulator use does not protect against unplanned direct contact with peripheral nerves during performance of a nerve block on an obtunded patient.

CT and MRI of massive osteolysis of Gorham.

Massive osteolysis of Gorham is a clinical, radiographic, and histologic entity characterized by histologically benign vascular proliferation involving bone associated with extensive osteolysis. We present CT and MRI findings of the disease and serial radiography following the progressing bone destruction.

CT and MRI of Gorham syndrome.

Gorham syndrome, also known as massive osteolysis or vanishing bone, is a rare disorder (135 cases reported) leading to extensive loss of bony matrix, replaced by proliferating thin-walled vascular channels. Three histologically proven cases of the disease are reported, including the clinical presentation and modern imaging features with CT (with 3D reconstruction) as well as T1- and T2-weighted MRI. Two cases in young women were located in the pelvis with extensive osteolysis reaching to the acetabulum. The third case in a 2-month-old boy is the youngest case ever reported and involved the humerus. The radiological appearance of the disease is discussed and the importance of the modern imaging methods debated.

Brachial plexus injury caused by impalement.

Open injuries of the brachial plexus are rare. One such case, that of a 68-year-old impaled on a fence spike, is presented here. Certain principles to guide evaluation and treatment are discussed. Concomitant injury to the pleura or to vascular structures requires immediate attention; the extent and type of plexus damage may be determined from physical findings and the nature of injury. The results of plexus reconstruction are variable and routine exploration may be detrimental. The Brooks classification is reviewed.
