Objectives: To describe the clinical and radiographic results of patients with traumatic recurrent anterior shoulder dislocation treated with the Bristow-Latarjet procedure. Methods: Retrospective case series including 44 patients (45 shoulders) who underwent the Bristow-Latarjet procedure. The graft was fixed “standing” in 84% of the shoulders, and “lying” in 16%. Results: The follow-up was 19.25 ± 10.24 months. We obtained 96% of good results, with 2 recurrences presented as subluxation. Graft healing occurred in 62% of cases. The graft was positioned below the glenoid equator in 84% of the cases, and less than 10 mm from its edge in 98%. The external rotation had a limitation of 20.7º ± 15.9º, while the internal rotation was limited in 4.0º ± 9.6º. The limitation of rotation and the position of the graft (“standing” or “lying”) did not correlate with graft healing (p>0.05). Bicortical fixation was positively correlated with healing (p <0.001). Conclusion: The Bristow-Latarjet technique is indicated for the treatment of recurrent anterior dislocations and subluxations of the shoulder. It is a safe treatment method, which can be used in people with intense physical activity. Limiting shoulder mobility does not prevent patients from returning to their usual occupations. Level of Evidence IV, Case series.
PURPOSE:To evaluate the amplitude of the subcoracoid space under maximum internal and external rotations of the humeral head and measure the distance between the apex of the coracoid process and the following anatomical structures: (a) point of entry of the musculocutaneous nerve and its branches into the coracobrachial muscles and into the short head of the biceps brachii muscle; (b) acromial artery; (c) lesser tubercle of the humerus. METHOD: Thirty shoulders of fresh cadavers, without any kind of shoulder pathology, (9 males and 6 females) were dissected, and the distances (in mm) were measured between the anatomical structures defined above and the apex of the coracoid process.
RESULTS:The mean distance between the apex of the coracoid process and the musculocutaneous nerve was 49.2 mm (in all specimens a proximal branch of the nerve was identified 34.2 mm away from the apex of the coracoid process), which was not significantly different between the sexes or body sides; the mean distance between the apex of the coracoid process and the acromial artery was 12.4 mm, which was not significantly different between the sexes or body sides; the mean distance between the apex of the coracoid process and the lesser tubercle of the humerus, with the humeral head under internal rotation, was 10.6 mm in men and 8.6 mm in women, values that were significantly different between the sexes. DISCUSSION: In women, the smaller distance between the apex of the coracoid process and the lesser tubercle of the humerus in the arm internal rotation suggests a higher chance of impingement between those bone structures among the female sex.
Study design: Clinical and radiographic evaluation of the shoulders of tetraplegic and paraplegic patients who attend rehabilitation program. Objectives: The objective of this study is to establish the usefulness of radiography as a trial exam for shoulder pain in spinal cord injured patients. Setting: Hospital das ClinicasFUNICAMP. Campinas, Sao Paulo, Brazil. Methods: Thirty-two shoulders of 16 patients were evaluated by clinical exam and radiography. Patients were divided into two groups: paraplegic and tetraplegic. A control group of 16 normal volunteer subjects was selected. Results: Shoulder pain was reported in 88.89% of tetraplegic and 42.85% of paraplegic. The time of injury ranged from 1.5-22 years (mean 7.88 years); patients had a mean age of 34.68 years (range, 21-57 years). The acromioclavicular joint (ACJ) space ranged from 0.03-0.7 cm on the right side and 0.15-0.7 cm on the left side, with a mean of 0.37 and 0.41 cm, respectively. No correlation was found between shoulder pain and gender, age or time since injury. There was a trend to correlation between shoulder pain and type of injury with tetraplegic having a tendency to pain symptoms. On average, tetraplegic had smaller ACJ. Conclusions: The small number of patients in this study did not allow us to confirm the hypothesis that X-ray finding may indicate risk for shoulder pain in spinal cord injury patients. A work with a greater number of subjects could demonstrate association between shoulder pain and the reduced acromioclavicular distance, making plain radiography a trial exam for spinal cord-injured patients.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
