Maximum Bridging Suture Tension Provides Better Clinical Outcomes in Transosseous-Equivalent Rotator Cuff Repair: A Clinical, Prospective Randomized Comparative Study.

Am J Sports Med 2020 Jun 18:363546520930425. Epub 2020 Jun 18.

Department of Orthopedic Surgery, Bundang Jesaeng General Hospital, Daejin Medical Center, Seongnam, Republic of Korea.

Background: Some studies reporting clinical outcomes after transosseous-equivalent (TOE) repair have attributed type II rotator cuff failure to excessive bridging suture tension, as it can cause overloading on the medial row. In a previous biomechanical cadaveric study, increasing bridging suture tension over 90 N did not improve the contact area and ultimate failure load of the TOE construct, despite increasing the contact force and contact pressure.

Purpose: To compare the clinical outcomes of different bridging suture tensions after TOE rotator cuff repair based on the results of a previous biomechanical study. Read More

Analysis of the Anatomical Factors Associated with Cubital Tunnel Syndrome.

Orthop Traumatol Surg Res 2020 Jun 30;106(4):743-749. Epub 2020 Apr 30.

Department of Orthopedic Surgery, Eulji University College of Medicine, 1306 Dunsan-dong, Seo-gu, 35233 Daejeon, Korea.

Background: Previous studies demonstrated that soft tissues, such as retinaculum, fibrous band, and anconeus, cause ulnar nerve compression, whereas other studies showed that the bony structures strain the ulnar nerve that runs directly behind the medial epicondyle constituting the boundary of the cubital tunnel during elbow flexion. However, no studies have reported the association of the shape of the bony structure with cubital tunnel syndrome symptoms. Are computed tomography (CT) and magnetic resonance imaging (MRI)-measured parameters of the bony cubital tunnel related to idiopathic cubital tunnel syndrome symptoms?
