An important landmark for determining appropriate radial head height that is often overlooked is the proximal radioulnar joint (PRUJ). We propose a methodology to use an en face view of the lesser sigmoid notch as a fluoroscopic reference point to establish appropriate height for the proximal border of the prosthesis in radial head replacement. 5 fresh frozen cadaveric elbows were dissected medially to assess the relationship of the radial head to the lesser sigmoid notch of the ulna while maintaining structural integrity of the lateral stabilizers. Plain radiographs of each elbow were obtained to define a true anteroposterior view of the PRUJ. The radial head and proximal ulna were resected to measure their cartilage thickness. The angle of the lesser sigmoid notch was found to be an average of 28.2 degrees, which correlated to a 30-degree external oblique radiograph of the elbow as providing an en face view of the PRUJ. The average thickness of the radial head cartilage rim in the coronal plane was 1.95 mm, while the middle aspect of the lesser sigmoid notch was 2.5 mm. A 30-degree lateral oblique radiograph of the elbow provides a true anteroposterior view of the PRUJ, which can be a useful adjunct for restoring radial length in situations such as radial head replacement or fracture repair.

Operative fixation can be challenging due to limited medial bone stock and adjacent vital vascular structures. Twenty-one consecutive chest computer topography (CT) scans were analyzed to measure anterior-posterior and superior-inferior dimensions of the medial clavicle. Correlation between height and clavicular dimensions were assessed by Pearson correlation coefficient. Two cases using dual T-locking plates are described. From anterior to posterior, the medial clavicle typically measures 1.44 (SD 0.26 cm) and 2.51 cm (SD 0.38 cm) at its narrowest and widest points, respectively. The mean superior-inferior width was 1.56 cm (SD 0.21 cm) and 2.76 cm (SD 0.39 cm) at its narrowest and widest points, respectively. Inter-observer reliability was 0.986 with combined intra-observer reliability between two time points of 0.984. Surgeons may use CT to reliably evaluate the amount of bone available for screw purchase and pre-operatively determine expected screw lengths. Locking plates using both unicortical locking screws and bicortical screws can be used for fracture fixation. Both patients healed fractures with dual T-locking plates without a short-term hardware complication. Dual T-locking plates may be a consideration for medial clavicle fracture fixation when medial bone purchase is a concern.</p>","PeriodicalId":44224,"journal":{"name":"Techniques in Shoulder and Elbow Surgery","volume":"20 1","pages":"26-29"},"PeriodicalIF":0.0,"publicationDate":"2019-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1097/BTE.0000000000000152","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"36947348","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

If triceps rupture is not immediately recognized, chronic ruptures produce a therapeutic problem. The residual tendon is often retracted, atrophic and of poor quality, therefore it is not usually appropriate for primary repair due to the high levels of tension encountered. Previously, multiple autograft techniques have been reported; however, this often leaves the patient with an additional surgical site and additional morbidity. Therefore we present our operative technique using acellular dermal allograft (ADA) as an interposition graft for the management of chronic distal triceps rupture. A 37-year-old male, right hand dominant, security guard presented to our institution’s orthopedic outpatient clinic with a 12-year history of weakness and deformity to his left arm. Preoperative magnetic resonance imaging demonstrated rupture of the distal triceps tendon. We performed an operative repair using an ADA in an interpositional manner. Ten months postoperatively magnetic resonance imaging demonstrated an intact repair, and at 19 months postoperatively the patient’s Disability of the Arm, Shoulder Hand (DASH) score was 0.83 and his strength was 72.8% of the contralateral side. Accordingly, we believe that using an interpositional ADA in our reported technique is a good option to treat chronic distal triceps rupture.","PeriodicalId":44224,"journal":{"name":"Techniques in Shoulder and Elbow Surgery","volume":"20 1","pages":"35–38"},"PeriodicalIF":0.0,"publicationDate":"2019-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1097/BTE.0000000000000161","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42239766","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
