Determination of rotator cuff tear reparability: an ultrasound-based investigation.

Background: The use of ultrasound as a viable diagnostic tool for routine office visit evaluation of rotator cuff integrity is slowly gaining acceptance in orthopedic practice. However, the reliability of accurately assessing rotator cuff tear reparability by ultrasound has limited evidence in the literature. The purpose of this study was to compare preoperative assessment of cuff tear reparability via ultrasound with the arthroscopic determination of reparability at the time of surgery. Methods: We prospectively collected preoperative ultrasound and arthroscopic imaging data on 145 patients (80 or 55% men and average age of 60.7 years) who underwent arthroscopic posterior superior rotator cuff repair. Three independent experienced orthopedic surgeons retrospectively reviewed all ultrasound studies and arthroscopic imaging and determined if the posterior superior rotator cuff tendon edge was able to be viewed via ultrasound and determined with the arthroscopic images if the tear was reparable. Results: On review of the ultrasound and arthroscopic data, if the edge of the rotator cuff tendon was able to be viewed on the coronal ultrasound image, it was most likely reparable with a positive predictive value of 97.6% and a positive likelihood ratio of 5.8. Sensitivity was 84.4%, and specificity was 76.9%. The negative predictive value was 37.5%, and the negative likelihood ratio was 0.17. The interobserver reliability was 0.63, and the observers were unanimous in determining the tendon edge was able to be visualized in 99 of 145 cases (68%). Conclusion: Preoperative ultrasound evaluation of the shoulder for posterior superior rotator cuff tears is a useful tool for assessing rotator cuff integrity and may help predict intraoperative reparability of the tendon. This study demonstrates that if the cuff tear edge is able to be visualized, there is a high probability of successful arthroscopic restoration of the tendon to its native attachment. Conversely, if the tear edge is unable to be visualized, there is a moderate chance of the tear being irreparable. These results help expand the knowledge base of the usefulness of in-office ultrasound performed by the surgeon in predicting the results of surgical intervention for rotator cuff tears.

Do we really need to order magnetic resonance imaging? Shoulder surgeon ultrasound practice patterns and beliefs.

BACKGROUND: Despite significant benefits, many orthopedic surgeons are hesitant to incorporate diagnostic ultrasound into their practice. This may be because of a lack of comfort, knowledge, and/or training. The purpose of this study was to analyze practice patterns regarding the use of shoulder ultrasound by orthopedic surgeons to diagnose rotator cuff tears. MATERIALS AND METHODS: We conducted a survey of the members of the American Shoulder and Elbow Surgeons (ASES) regarding their use of ultrasound. A systematic review of the literature on the use of ultrasound in the shoulder by orthopedic surgeons was also performed. RESULTS: Of the members of ASES responding to the survey, 55% are using ultrasound for diagnostic purposes in the shoulder. The leading reason for not using ultrasound as the sole imaging modality prior to performing rotator cuff repair was lack of confidence in the ability to determine the reparability of the tear (83%). Our systematic review showed that for an orthopedic surgeon diagnosing a full-thickness rotator cuff tear, the mean sensitivity was 92% and mean specificity was 89%. CONCLUSIONS: Many ASES surgeons are not using ultrasound in the shoulder despite its many potential benefits over magnetic resonance imaging. This is because of a lack of confidence in the ability to quantify fatty infiltration, muscle atrophy, and the level of retraction medial to the acromion. Our systematic review showed that orthopedic surgeons can be accurate in the diagnosis of full-thickness rotator cuff tears. Future research should focus on defining parameters of shoulder ultrasound associated with rotator cuff tendon reparability. Educating surgeons on ultrasound technique, cost, and evidence may be a promising strategy to enhance the value in musculoskeletal care delivery.

Release of the stiff elbow with mini-open technique.

BACKGROUND: Currently, there are many techniques used in the surgical release of elbow contracture, but no single technique has gained widespread acceptance. The purpose of this study was to report the outcomes of a lateral-column approach combined with a mini-open triceps-splitting technique for elbow contracture release. METHODS: Thirty-six patients with a mean age of 39 years were included in the study. All patients underwent a combined lateral and minimal posterior triceps-splitting open elbow contracture release. Elbow range of motion and visual analog scale pain scores were recorded. The Mayo Elbow Performance Score was used to assess functional outcome. RESULTS: The mean follow-up period was 38 months. Mean pain levels decreased from 7.59 preoperatively to 0.44 postoperatively (P < .05). The total arc of elbow motion increased from 52° preoperatively to 109° postoperatively, with an improvement of 57° (P < .05). The Mayo Elbow Performance Score improved from 44.17 preoperatively to 90.83 postoperatively (P < .05). CONCLUSION: This study shows that a combined lateral and mini-open triceps-splitting approach is a safe and effective alternative technique for the treatment of elbow contractures.
