BACKGROUND: Placement of the glenoid baseplate is of paramount importance for the outcome of anatomical and reverse total shoulder arthroplasty. However, the database around glenoid size is poor, particularly regarding small scapulae, for example, in women and smaller individuals, and is derived from different methodological approaches. In this multimodality cadaver study, we systematically examined the glenoid using morphological and 3D-CT measurements. METHODS: Measurements of the glenoid and drill hole tunnel length for superior baseplate screw placement were recorded to define size of the glenoid and the distance to the scapular notch on cadaveric specimens...

PURPOSE: The arthroscopic Latarjet procedure has provided reliable results in the treatment of anterior shoulder instability. However, this procedure remains technically challenging and is related to several complications. The morphology of the coracoid and the glenoid are inconsistent. Inadequate coracoid and glenoid preparing may lead to mismatching between their surfaces. Inadequate screws lengthening and orientation are a major concern. Too long screws can lead to suprascapular nerve injuries or hardware irritation, whereas too short screws can lead to nonunions, fibrous unions or migration of the bone block...

OBJECTIVE: Shoulder stabilization. INDICATIONS: Symptomatic recurrent anterior shoulder instability combined with glenoid bone loss of approximately 20-35 % of the glenoid surface, engaging Hill-Sachs lesion and/or previously failed arthroscopic Bankart repair. In patients with a high risk of redislocation (contact sports) or irreparable soft tissue injury the Latarjet procedure can be considered as a first-line treatment. CONTRAINDICATIONS: Contraindicated if arthroscopic Bankart repair is possible...

PURPOSE: For the success of Latarjet procedure a correct graft positioning is mandatory. Furthermore, the correct screw placement is important to avoid cartilage damage and soft tissue irritation. Due to a cadaveric experimental study, the accuracy of graft and screw positioning utilizing a novel drill guide for a minimal-invasive Latarjet procedure was analyzed. METHODS: Five human fresh-frozen shoulder specimens have been treated in accordance with the Congruent-Arc Latarjet technique using the glenoid bone loss set (Arthrex, Naples, FL, USA) with 3...

PURPOSE: The first purpose of this study is to measure the distance between the axillary nerve and the exit point of K-wires placed retrograde through the glenoid in the setting of an arthroscopic Latarjet procedure. The second objective is to evaluate whether manual external rotation of the scapula alters that distance. METHODS: In seven fresh-frozen specimens, two 2.0-mm K-wires were drilled through the glenoid using an arthroscopic Latarjet retrograde glenoid guide...

PURPOSE: The aim of our study was to evaluate the risk of medial glenoid perforation and possible injury to suprascapular nerve during arthroscopic SLAP repair using lateral transmuscular portal. METHODS: Ten cadaveric shoulder girdles were isolated and drilled at superior glenoid rim from both anterior-superior portal (1 o'clock) and lateral transmuscular portal (12 o'clock) for SLAP repairs. Drill hole depth was determined by the manufacturer's drill stop (20 mm), and any subsequent drill perforations through the medial bony surface of the glenoid were directly confirmed by dissection...

INTRODUCTION: Glenoid loosening is one of the most common complications of anatomic total shoulder arthroplasty (aTSA). Numerous glenoid pegged designs exist within the market place; however, little effort has been made to optimize peg geometry, and as a result, there is no consensus regarding the superiority of one design over another. The aim of this study was to determine the impact of peg design on the fixation strength by comparing the force and displacement associated with five different geometries of cemented glenoid components when each is axially displaced from two different densities of polyurethane bone substitute substrates...

PURPOSE: Successful total shoulder arthroplasty (TSA) requires a correct position of the glenoid component. This study compares the accuracy of the positioning with a new developed glenoid aiming device and virtual three-dimensional computed tomography (3D-CT) scan positioning. MATERIALS AND METHODS: On 39 scapulas from cadavers, a K-wire (KDev) was positioned using the glenoid aiming device. It consists of glenoid components connected to the aiming device, which cover 150° of the inferior glenoid circle, has a fixed version and inclination and is available with several different radii...

INTRODUCTION: One of the main causes of recurrent shoulder instability is a bone defect of the front edge of the glenoid. The available techniques for reconstruction of this bone defect, however, have some disadvantages. OBJECTIVE: The aim of this study was to develop a new method that can reduce the number of postoperative complications and improve the efficiency of surgical treatment of recurrent anterior shoulder instability with glenoid bone defect. MATERIALS AND METHODS: We present here a new method for surgical treatment of post-traumatic recurrent anterior shoulder instability with bony defects using porous NiTi...

Shoulder instability can be a challenging condition to treat when it becomes refractory to soft-tissue procedures or when bone loss exceeds 25% to 27% of the glenoid. The Bristow-Latarjet procedure has been developed and popularized to deal with these concerns. Traditionally, the procedure has been performed as an open approach; however, this has been recently supplanted by novel arthroscopic techniques. We present a technique for the procedure performed with the patient in a semi-lateral decubitus position that assists with optimal graft placement on the native glenoid...

BACKGROUND: A substantial challenge in total shoulder replacement is accurate positioning and alignment of the glenoid component. This challenge arises from limited intraoperative exposure and complex arthritic-driven deformity. We describe a novel pin array guide and method for patient-specific guiding of the glenoid central drill hole. We also experimentally tested the hypothesis that this method would reduce errors in version and inclination compared with 2 traditional methods. METHODS: Polymer models of glenoids were created from computed tomography scans from 9 arthritic patients...

BACKGROUND: Here we investigated the angle and placement of bone holes for suture anchors using postoperative computed-tomography scapula scans. METHODS: The study group comprised 20 shoulders from 20 consecutive patients (13 males and seven females; mean age 23.4 years) who underwent arthroscopic Bankart repair. All anchors were inserted through the anterior portal after establishing a bone hole at the edge of the glenoid articular surface using a drill. Computed tomography images of the scapula were taken 1 month postoperatively and used to create three-dimensional scapula models with Mimics and Magics software...

Recurrent shoulder instability often leads to labral abnormality that requires surgical intervention that may require fixation with suture anchors. The proposed surgical technique allows the surgeon to achieve 2 points of fixation around the labrum and/or capsule with a single suture secured to the glenoid with a knotless anchor. Instead of cutting and discarding the residual suture limbs after anchor insertion, this technique uses the residual suture limbs of the knotless anchor for a second suture pass. This technique (1) creates a more cost- and time-efficient surgical procedure than using multiple single-loaded anchors or double-loaded anchors, (2) decreases the known risk of glenoid fracture from the stress riser at the implant tips of multi-anchor repairs by reducing the number of anchors required for stabilization, (3) decreases the surgical time compared with the use of double-loaded anchors through simpler suture management and less knot tying, (4) allows for the secure reapproximation of the labrum to the glenoid while offering a convenient option for capsulorrhaphy without the need to insert another anchor, and (5) yields more points of soft-tissue fixation with fewer anchors drilled into the glenoid...

PURPOSE: The purpose of this study was to compare the risk of injury to the suprascapular nerve during suture anchor placement in the glenoid when using an anterosuperior portal versus a rotator interval portal. METHODS: Ten bilateral fresh human cadaveric shoulders were randomized to anchor placement through the anterosuperior portal on one shoulder and the rotator interval portal on the contralateral shoulder. Standard 3 × 14 mm suture anchors were placed in the glenoid rim (1 o'clock, 11 o'clock, and 10 o'clock positions for the right shoulder)...

We present a novel all-arthroscopic technique of posterior shoulder stabilization that uses suture anchors for both bone block fixation and capsulolabral repair. The bone graft, introduced inside the glenohumeral joint through a cannula, is fixed with 2 suture anchors. The associated posteroinferior capsulolabral repair places the bone block in an extra-articular position. In this article we present the detailed arthroscopic technique performed in a consecutive series of 15 patients and report the early results...

BACKGROUND: The accuracy of reproducing a surgical plan during shoulder arthroplasty is improved by computer assistance. Intraoperative navigation, however, is challenged by increased surgical time and additional technically difficult steps. Patient-matched instrumentation has the potential to reproduce a similar degree of accuracy without the need for additional surgical steps. The purpose of this study was to examine the accuracy of patient-specific planning and a patient-specific drill guide for glenoid baseplate placement in reverse shoulder arthroplasty...

Shoulder and hip osteochondritis dissecans (OCD) are uncommon. Both glenoid and humeral head OCD are commonly associated with a traumatic etiology. Humeral head OCD can be treated with observation or drilling of the sclerotic margin for stable or unstable lesions. Glenoid OCD often presents with delamination of the articular cartilage and requires debridement and fixation of fragments. Hip OCD often involves the femoral head; yet, there are case reports of acetabular involvement. The etiology of femoral OCD is associated with other pathologies, and therefore may represent the sequelae of other disease processes...

BACKGROUND: During arthroscopic Bankart repair, inferior anchor placement is critical to a successful outcome. Low anterior anchors may be placed with a standard straight guide via midglenoid portal, with a straight guide with trans-subscapularis placement, or with curved guide systems. Purpose/ HYPOTHESIS: To evaluate glenoid suture anchor trajectory, position, and biomechanical performance as a function of portal location and insertion technique. It is hypothesized that a trans-subscapularis portal or curved guide will improve anchor position, decrease risk of opposite cortex breach, and confer improved biomechanical properties...
