Abstract: The open Latarjet procedure has proven to be an effective procedure in the treatment of anterior shoulder instability, particularly in patients with glenoid bone loss and/or an engaging Hill-Sachs lesion. The transfer of the coracoid bone block to the anterior glenoid provides stability via the “triple blocking effect”.

Provencher, M.D., C.A.PT., M.C., U.S.N.R. Abstract: Recurrent multidirectional shoulder instability (MDI) is a challenging clinical problem, particularly in the setting of connective tissue diseases, and there is a distinct lack of literature discussing strategies for operative management of this unique patient group. These patients frequently present with significant glenoid bone loss, patulous and abnormal capsulolabral structures, and a history of multiple failed arthroscopic or open instability procedures. Although the precise treatment algorithm requires tailoring to the individual patient, we have shown successful outcomes in correcting recurrent MDI in the setting of underlying connective tissue disorders by means of a modified T-plasty capsular shift and rotator interval closure in conjunction with distal tibial allograft bony augmentation. The purpose of this Technical Note was to describe a technique that combines a fresh distal tibial allograft for glenoid bony augmentation with a modified T-plasty capsular shift and rotator interval closure for the management of recurrent shoulder MDI in patients presenting with Ehlers-Danlos syndrome or other connective tissue disorders after failed Latarjet stabilization. ecurrent multidirectional shoulder instability Conversely, MDI without hyperlaxity is more likely to R(MDI) is a difficult clinical problem and becomes present with anterior and/or posterior capsulolabral even more challenging in the face of connective tissue pathology1,2 in addition to bony lesions.

    The Open Eden-Hybinette Procedure for Recurrent Anterior Shoulder Instability With Glenoid Bone Loss Joseph W. Galvin, DO,* Zachary R. Zimmer, MD,* Alexander M. Prete, BS,* and Jon J.P. Warner, MD* In the setting of significant glenoid bone loss, soft tissue stabilization procedures for recur- rent anterior shoulder instability have high failure rates. The open or arthroscopic Eden- Hybinette procedure with tricortical iliac crest autograft has been shown to provide good results with low rates of recurrent instability. Indications for this technique include severe glenoid bone loss (>40%), recurrent instability following a Latarjet or distal tibial allograft procedure, or patients with abnormal coracoid morphology. In this technique article, we review the indications, contraindications, surgical technique, postoperative care, out- comes, and complications of the open Eden-Hybinette procedure.

  • The Biomechanics of the Latarjet Reconstruction: Is It All About the Sling? Nobuyuki Yamamoto, MD,* and Scott P
    The Biomechanics of the Latarjet Reconstruction: Is It All About the Sling? Nobuyuki Yamamoto, MD,* and Scott P. Steinmann, MD† It has been clinically believed that the stabilizing mechanism of the Latarjet procedure is the sling effect. Biomechanical studies have demonstrated that there are 3 stabilizing mecha- nisms of the Latarjet procedure, the main one being the sling effect produced by the sub- scapularis and conjoint tendons. The other 2 mechanisms are the suturing of the capsular flap at the end-range arm position and reconstruction of the glenoid concavity at the mid- range arm position. All 3 stabilizing mechanisms function at both the mid- and end-range arm positions. After the Latarjet procedure, the shoulder even with a large glenoid defect can have stability increased by 14% compared to the normal shoulder. The acceptable clini- cal outcomes of the Latarjet procedure are supported by these 3 stabilizing mechanisms. Oper Tech Sports Med 27:49-54 © 2019 Elsevier Inc. All rights reserved.

Abstract ID: Paper 001 *Chelsea S. Mathews, M.D. / Little Rock, AR Karan D. Dua, M.D. / Baltimore, MD Austin A. Cole / Little Rock, AR Eric R. Siegel, M.S. / Little Rock, AR Joshua M. Abzug, M.D. / Baltimore, MD Theresa O. Wyrick, M.D. / Little Rock, AR INTRODUCTION: Ulnar artery thrombosis (UAT), or hypothenar hammer syndrome, has strong correlations with individuals involved in manual labor and various athletic professions. Activities that produce a persistent impact on the hypothenar eminence can damage blood vessels of the hand, specifically the ulnar artery as it passes through Guyon’s canal. To our knowledge, the prevalence of these symptoms residing in orthopedic surgeons is unknown. We hypothesized that orthopedic surgeons would have an increased prevalence of UAT than the general population and that this would be true of surgeons who perform a large volume of hip and knee arthroplasty due to frequent use of oscillating saws and methods of retractor placement. METHODS: 80 current, retired, and resident orthopedic surgeons at two separate institutions were surveyed for symptoms of ulnar artery thrombosis (UAT). Participants completed surveys indicating symptoms of UAT and participation in leisurely activities that may also increase their risk. A timed Allen’s test was performed with the radial artery occluded and the time to reperfusion of the hand was measured.

  • Open Latarjet: a Reliable, Successful Method to Prevent Recurrence in the Presence of Bony Defects Kevin D
    Open Latarjet: A Reliable, Successful Method to Prevent Recurrence in the Presence of Bony Defects Kevin D. Plancher, MD,†,‡,§ Stephanie C. Petterson, PhD,† and Gilles Walch, MD* Glenoid bone loss may dictate the success of procedures to restore anterior shoulder instability. The Latarjet procedure addresses bony defects to minimize the risk of recurrence in this subset of patients with bone loss in both athletes and non-athletes alike. This article describes a modified, open Latarjet procedure using a subscapularis splitting technique that provides stability through the triple-blocking effect previously described by Patte et al. The “sling effect”, a dynamic effect created by the transfer of the conjoint tendon, provides stabilization in abducted and externally rotated arm positions particularly at mid and end ranges of motion. Augmentation of the anteroinferior glenoid increases or restores the glenoid diameter to provide stability through a “bone blocking effect”. Lastly, stability is achieved by repairing the capsule to the coracoacromial ligament stump. This open procedure has been utilized successfully when a physician is confronted by this difficult clinical scenario. Oper Tech Sports Med 21:238-245 C 2013 Elsevier Inc. All rights reserved.

  • A Pilot Study of Blood Supply of the Coracoid Process and the Coracoid Bone Graft After Latarjet Osteotomy

The coracoid process (CP) is the main structure of this surgery. However, the blood supply of CP is not fully understood, and the extent of destruction of blood supply of coracoid bone graft after Latarjet osteotomy procedure is still controversial. Five embalmed cadaveric upper limbs specimens were employed for macro observation of the blood supply of CP. The conjoint tendon (CT) and CP interface were dissected for histology. Sixteen fresh frozen shoulder specimens were used for perfusion and micro CT scanning. Eight specimens were used to present the whole vessel structure of CP.The other eight underwent Latarjet osteotomy procedure. The coracoid bone grafts in both groups were scanned to clarify the remnant blood supply. It was found that the CP was nourished by supra-scapular artery (SSA), thoracic-acromial artery and branch from second portion of the axillary artery (AA).
