1/19. An operative technique for recurrent shoulder dislocations in older patients.Recurrent anterior shoulder dislocation in the elderly is not as exceptional as it was once thought to be. That anterior shoulder dislocation in older patients is caused by a rotator cuff tear through the posterior mechanism is well accepted. However, in the subset of patients who have multiple recurrent or intractable dislocations develop, there may be combined pathologic conditions at work: large or massive rotator cuff tears together with anterior capsulolabral injuries such as a Bankart lesion or fracture of the glenoid rim. These patients have multiple recurrences because of disruption of both the anterior and the posterior stability mechanisms. We suggest a procedure that provides anterior stabilization with the capsular shift technique and that is supplemented by Bankart repair as necessary. The capsule transfer is performed superiorly and posteriorly to close the defect in the cuff. In this way a capsulodesis effect can be achieved that displaces the humeral head downward and produces active centering of the head in the course of abduction. Use of only the anterior capsule for the shift, and not the subscapularis tendon, does not compromise subscapularis function. Between 1990 and 1996, we used this technique to treat 16 patients older than 55 years of age with multiple recurrent anterior shoulder dislocation and massive rotator cuff tear. We report the results for the first 10 patients with a minimum follow-up of 2 years (range 2 to 7 years) and an average follow-up of 52 months. There were 7 excellent results, 2 good results, and 1 fair result according to the Rowe criteria. None of the patients had a recurrence of the dislocation. All the patients regained full or functional range of motion with stable shoulders, and most of them could perform activities of daily living without limitation. The average Constant score was 83%. This procedure appears to be successful in treating older patients with recurrent shoulder dislocation.- - - - - - - - - - ranking = 1keywords = fracture (Clic here for more details about this article) |
2/19. Severe heterotopic ossification after arthroscopic acromioplasty: a case report.Heterotopic ossification is a well-recognized complication of spinal cord injury, closed head injury, total hip arthroplasty, burns, and other trauma and has been observed in various tissues such as muscles, tendons, ligaments, and menisci. Complications of arthroscopic acromioplasty are relatively uncommon and include hematoma, traction neuropathy, infection, acromial fracture, reflex sympathetic dystrophy, and instrument breakage. However, little has been reported on heterotopic ossification of the shoulder, particularly after arthroscopic surgery. Recurrent rotator cuff impingement symptoms caused by small amounts of heterotopic ossification after arthroscopic acromioplasty have been described. We report a case of severe heterotopic ossification about the shoulder after arthroscopic acromioplasty.- - - - - - - - - - ranking = 1keywords = fracture (Clic here for more details about this article) |
3/19. Suprascapular nerve entrapment at the spinoglenoid notch in a professional baseball pitcher.Suprascapular nerve injuries at the spinoglenoid notch are uncommon. The true incidence of this lesion is unknown; however, it appears to be more common in athletes who participate in sports involving overhead activities. When a patient is being evaluated for posterior shoulder pain and infraspinatus muscle weakness, electrodiagnostic studies are an essential part of the evaluation. electromyography will identify an injury to the suprascapular nerve as well as assist in localizing the site of injury. In addition, imaging studies are also indicated to help exclude other diagnoses that can mimic a suprascapular nerve injury. The initial management should consist of cessation of the aggravating activity along with an organized shoulder rehabilitation program. If the patient fails to improve with 6 months to 1 year of nonoperative management, surgical exploration of the suprascapular nerve should be considered. Release of the spinoglenoid ligament with resultant suprascapular nerve decompression may result in relief of pain and a return of normal shoulder function.- - - - - - - - - - ranking = 0.099379160243781keywords = compression (Clic here for more details about this article) |
4/19. Quadrilateral space syndrome: diagnosis, pathology, and treatment.Quadrilateral space syndrome is an infrequent, recently established neurovascular compression syndrome affecting young active adults. With this syndrome, the neurovascular bundle, consisting of the posterior humeral circumflex artery (PHCA) and the axillary nerve, is compressed by fibrotic bands as it traverses the quadrilateral space. Symptoms result from compression of the axillary nerve, not from PHCA occlusion. Because of the vague, often nonspecific, clinical presentation of patients with quadrilateral space syndrome, diagnosis is challenging and requires a high index of suspicion from the orthopedist. Subclavian arteriography confirms the diagnosis. Treatment is usually conservative; operative management is reserved for selected patients. A posterior approach with detachment of the deltoid and teres minor muscles is recommended for surgical decompression and for lysis of fibrous tissue. We report two cases of persistent quadrilateral space syndrome in young adults, treated surgically, with 2-year follow-up. In the present report, diagnostic criteria, pathology, management, operative technique, and recent literature are also reviewed.- - - - - - - - - - ranking = 0.29813748073134keywords = compression (Clic here for more details about this article) |
5/19. shoulder pain as an unusual presentation of pneumonia in a stroke patient: a case report.Etiologies of shoulder pain in the hemiplegic population, such as glenohumeral subluxation, frozen shoulder, and reflex sympathetic dystrophy (RSD), have been described extensively. We present an 89-year-old woman with right hemiparesis secondary to ischemic lacunar infarction who developed sudden onset of right shoulder pain on the fifth day of inpatient rehabilitation. The pain was severe, limiting range of motion (ROM) and participation in therapy. Extensive investigations to rule out subluxation, fracture, connective tissue disease, RSD, and pulmonary embolism were negative. Ultimately, her shoulder pain and decreased ROM completely resolved with antibiotic treatment for right lower lobe pneumonia. We conclude that her symptoms were possibly referred pain from diaphragmatic irritation transmitted via right C4 sensory axons in the phrenic nerve, which shares the same dermatome as the right acromion area. This case was an unusual presentation of pneumonia in an elderly woman with hemiplegia. We recommend that pneumonia be considered in the differential diagnoses of shoulder pain.- - - - - - - - - - ranking = 1keywords = fracture (Clic here for more details about this article) |
6/19. Quadrilateral space syndrome: case report and review of the literature.The quadrilateral space syndrome is defined as tenderness over the quadrilateral space and shoulder pain radiating to the arm, secondary to compression of the axillary nerve and posterior circumflex humeral artery in the quadrilateral space. The symptoms are aggravated by forced abduction and extrenal rotation of the arm. The diagnosis is clinical and is documented by arteriography or angio-MR imaging with dynamic maneuvers. A 30-year-old woman presenting with this syndrome is described here, the differential diagnosis discussed, and the literature reviewed.- - - - - - - - - - ranking = 0.099379160243781keywords = compression (Clic here for more details about this article) |
7/19. Arthroscopic treatment of coracoid impingement.A review of the literature reveals that surgical treatment of coracoid impingement has heretofore involved open surgical decompression in all cases. Previously unreported, the authors describe an arthroscopic technique to treat coracoid impingement syndrome, demonstrate its feasibility, and cover the specific technical points that facilitate this procedure.- - - - - - - - - - ranking = 0.099379160243781keywords = compression (Clic here for more details about this article) |
8/19. Two cases of isolated first rib fracture.Isolated first rib fractures are uncommon. They are usually associated with severe blunt trauma, although other mechanisms have been suggested, these being (a) indirect trauma, (b) sudden contraction of the neck muscles, and (c) stress or fatigue fractures attributable to repeated pull of muscles. Two cases are reported of stress fracture of the first rib, who presented to the accident and emergency department.- - - - - - - - - - ranking = 7keywords = fracture (Clic here for more details about this article) |
9/19. Enlarged spinoglenoid notch veins causing suprascapular nerve compression.OBJECTIVE: To report the magnetic resonance (MR) imaging findings of enlarged veins in the spinoglenoid notch as a cause of suprascapular nerve compression. DESIGN AND patients: Six patients presented to MR imaging for evaluation of chronic shoulder pain. Clinical information and MR imaging studies were reviewed. The spinoglenoid notch vascular structures were compared with measurements made in 10 age-matched controls. RESULTS: Spinoglenoid notch vascular structures measured in 10 asymptomatic age-matched control patients ranged from 1 to 4 mm in diameter with an average of 2.2 mm. The six study patients had vascular structures that ranged from 6 to 10 mm in diameter with an average of 8.4 mm. atrophy and fatty infiltration of the infraspinatus muscle was noted as an associated finding at MR imaging in all six patients. Surgery was performed in three of the six patients, at which time a venous varix was identified in the spinoglenoid notch in all three patients. CONCLUSION: We describe distended veins in the spinoglenoid notch. These may be readily apparent at MR imaging and should be distinguished from paralabral ganglion cysts compressing the suprascapular nerve in the absence of labral tears, especially if percutaneous aspiration of a ganglion cyst is entertained.- - - - - - - - - - ranking = 0.49689580121891keywords = compression (Clic here for more details about this article) |
10/19. Arthroscopic management of painful and stiff scapulothoracic articulation.We present the case of a patient who had chronic refractory scapulothoracic pain accompanied by the loss of scapulothoracic motion. Despite intensive physical therapy, the insidious onset of scapulothoracic pain and stiffness progressed. A wide range of diagnostic tests did not show a systemic, anatomic, or neurologic cause for the disorder. Finally, the patient elected to undergo an arthroscopic release and decompression of the scapulothoracic articulation. The patient had a dramatic response to surgery; the pain was gone immediately, and by 4 months after surgery, her scapulothoracic motion was evaluated as symmetric. One year after the surgery, she maintained an active lifestyle and was extremely satisfied with the result. Progressive and painful loss of shoulder motion in the case reported was due to a rare adhesive inflammation of the scapulothoracic bursa, which was successfully treated using arthroscopic resection. arthroscopy of the scapulothoracic articulation is an option to treat scapulothoracic abnormalities, especially bursitis, but long-term clinical studies are needed to strongly recommend this emerging treatment option.- - - - - - - - - - ranking = 0.099379160243781keywords = compression (Clic here for more details about this article) |
