Purpose: Various reconstruction methods have been proposed to reduce reflux after proximal gastrectomy, and we report here a double shouldering technique. The purpose of this study is to compare the novel double shouldering technique with conventional esophagogastrostomy in terms of short term and 3-year clinical outcome.
Methods: A retrospective observational case control study was performed on 63 patients for cT1N0 upper third gastric cancer who underwent proximal gastrectomy from January 2012 to November 2016 at the National Cancer Center, Korea. There were 26 patients with conventional esophagogastrostomy, and 37 patients with novel double shouldering technique. The primary outcome was endoscopic reflux esophagitis findings one and three year after surgery according to Los Angeles classification. Secondary outcomes were short term surgical outcome and reflux symptom.
Results: There was no significant difference in reflux esophagitis on endoscopic findings at 1 and 3 years after surgery between the two group. The double shouldering (DS) technique group showed significantly better postoperative outcomes with bile reflux at one and three years via endoscopic findings versus conventional esophagogastrostomy (CEG). Operative time and hospital stay were significantly shorter in the CEG group than the DS group. There was no significant difference in terms of reflux symptoms and complications.
Conclusion: This novel DS technique is a reconstruction method for use after proximal gastrectomy. It did not show a significant clinical benefit. Development of surgical techniques and further study is needed to identify the optimal reconstruction method after proximal gastrectomy.

The design of drill pipe joint thread with unequal taper is proposed to investigate the fracture failure of the API NC38 used in the drill pipe joint of the SU36-8-4H2 well. The effect of changes in thread taper on the stress distribution and mechanical properties of drill pipe joints is analyzed and compared with the API standard thread to determine the optimal thread structure with unequal taper. The results reveal highly concentrated stress at the last engaged thread root of API NC38 single-shoulder thread (SUT) may cause early yield failure of the joint threads.

Background: The lateral locking plate for the proximal humerus is currently the most commonly used surgical procedure for the treatment of elderly proximal humeral comminuted fractures. Previous studies have found that the rate of postoperative complications in patients of proximal humerus fractures with medial column involvement is relatively high. Through biomechanical methods, this study aims to investigate the effectiveness of the conventional lateral locking plate fixation along with the addition of the metacarpal supporting plate on the medial column in the treatment for proximal humeral fractures involving the medial column.

The BioWick anchor (Zimmer-Biomet) is an interpositional scaffold-anchor that was developed to improve tendon-bone healing. The purpose of this study was to determine the clinical efficacy of this novel anchor compared with a standard anchor with respect to retear rates and patient outcomes.

Successful subscapularis repair in stemless shoulder arthroplasty is crucial to reduce complications and improve postoperative function. As stemless shoulder arthroplasty continues to grow in popularity, several subscapularis tendon repair techniques are being developed, with a current trend toward knotless devices and double-row anchor-based constructs. In this article, we present our technique for repair of a subscapularis tendon peel using a suture-capture construct that aids in compression of the tendon onto its footprint and then gradually releases the tension as the capture resorbs and tendon healing occurs.

Background: Sternoclavicular joint dislocation (SJD) is rare, and joint instability after dislocation easily leads to deformity, pain, and limitations in performing activities, often requiring surgical treatment. Currently, there is no ideal internal fixation method for SJD.
Case Presentation: We report the case of a 38-year-old female patient with anterior dislocation of the right sternoclavicular joint (SJ) caused by a car accident who underwent open reduction and internal fixation using the double plate technique combined with the cable technique.
