Replicating the original bony anatomy during radial head replacement or fracture repair is important for both joint stability and prevention of arthritis, but can be difficult to achieve. 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. Level of Evidence: Basic science study.

The authors describe a novel all-arthroscopic anchorless transosseous suture technique that is easy to perform and reproduce and combines the benefits of both the arthroscopic technique and the transosseous approach. This procedure maximizes the tendon-footprint contact area obtaining both medial and lateral fixation without using any implanted device. In the current technical note, the procedure is described in detail providing several tips and tricks.

The management of massive irreparable rotator cuff tears is a challenge for surgeons. Unlike smaller rotator cuff tears massive irreparable tears cannot be managed through standard surgical techniques and have high rates of retear after surgical repair. Interpositional graft reconstruction is a novel surgical technique to manage these massive irreparable tears, with promising preliminary clinical outcomes. In the past interpositional graft reconstructions of massive irreparable rotator cuff tears were complex and invasive, open procedures, however more recently, with the development of specialized devices, a number of techniques have been described utilizing a simpler arthroscopic approach. Currently described in the literature, there are 2 open and 4 arthroscopic techniques for interpositional graft reconstruction of massive irreparable rotator cuff tears that have been performed on human patients. The aim of this review is to provide an overview of 6 techniques for interpositional graft reconstructions of massive irreparable rotator cuff tears.

Patients with poor bone quality or cystic changes present a unique problem when utilizing standard arthroscopic rotator cuff and labral repair techniques and implants. Previous studies have looked at multiple methods to augment the bone in the presence of poor bone quality to allow for appropriate fixation with variable success. The following case reports describe the use of AccuFill, an injectable calcium phosphate bone void filler, to augment rotator cuff or labral repair in the setting of deficient bone in the greater tuberosity or glenoid. In the rotator cuff repair case report, follow-up imaging at 1 year show tendonhealing, radiographic resolution of the cyst, and the patient returned to full function without postoperative complications. In the deficient posterior glenoid bone stock case report the technique allowed robust posterior labral advancement and repair and solid purchase of suture anchors; with 1-year follow-up imaging showing no reformation of the cyst. In both cases, patients underwent the procedure without significant increase in operative time or technique difficulty.

Significantly displaced medial clavicle fractures are associated with high rates of painful nonunion. 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.
显著移位的内侧锁骨骨折与疼痛不愈合的高发生率相关。由于有限的内侧骨和邻近的重要血管结构，手术固定可能具有挑战性。我们分析了21个连续的胸部计算机断层扫描(CT)来测量内侧锁骨的前后和上下尺寸。采用Pearson相关系数评价身高与锁骨尺寸的相关性。描述了使用双t型锁定板的两种情况。从前到后，内侧锁骨最窄处和最宽处的尺寸分别为1.44 (SD 0.26 cm)和2.51 cm (SD 0.38 cm)。最窄处和最宽处的平均优劣势宽度分别为1.56 cm (SD 0.21 cm)和2.76 cm (SD 0.39 cm)。观察者间信度为0.986，两个时间点间联合观察者内信度为0.984。外科医生可以使用CT可靠地评估可用于购买螺钉的骨量，并在术前确定预期的螺钉长度。单皮质锁定螺钉和双皮质锁定螺钉均可用于骨折固定。两例患者均采用双t型锁定钢板愈合骨折，无短期内硬件并发症。当需要购买内侧骨时，可考虑使用双t型锁定钢板固定内侧锁骨骨折。

Rupture of the triceps is a rare event. 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.

Corrective osteotomy for complex deformity correction is a challenging procedure, both in its planning and execution. Traditional planning techniques, particularly when applied to periarticular deformity, are generally inaccurate and the outcome of subsequent osteotomy may be suboptimal. In this described technique, 3-dimensional printed models were generated from preoperative computed tomographic scans to assist in both the planning and execution of a distal humeral osteotomy. A single case is described of cubitus valgus of 40 degrees with fixed flexion deformity following nonunion of a fracture of the lateral condyle of the humerus.
