Over 89% of Patients Return to Work After Undergoing Arthroscopic or Open Latarjet Procedure for Anterior Shoulder Instability: A Systematic Review. Arthroscopy 2024:S0749-8063(24)00781-3. [PMID: 39393429 DOI: 10.1016/j.arthro.2024.09.056] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/01/2024] [Revised: 09/28/2024] [Accepted: 09/29/2024] [Indexed: 10/13/2024]
Abstract
PURPOSE To better define the rate of return to work in patients undergoing Latarjet surgery for anterior shoulder instability METHODS: A systematic review was performed in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines. PubMed, Cochrane Center Register of Controlled Trials (CENTRAL), and Scopus were queried in October 2023 with the following keywords: ((latarjet) OR (anterior shoulder instability)) AND ((work) or (compensation)). Articles were included if they reported return to work in patients (including military members) undergoing Latarjet surgery for traumatic anterior shoulder instability with bone loss and were written in English. This study was registered in Prospero (ID blinded). RESULTS Six studies reporting on 419 shoulders were included in the review. Five studies reported on patients in the general population, and one reported on military members. Mean age ± standard deviation (SD) of patients ranged from 23.1 ± 5.8 - 32.0 ± 12.3 years old. Moreover, there were 286 primary Latarjet procedures, 131 revision Latarjet procedures, and 2 unspecified as primary or revision surgery. Mean glenoid bone loss ranged from 14.5% to 22.9%. Return to work rates ranged from 89.1% to 100%, with two studies reporting all patients were able to return to work. Among military members, 89.1% were able to return to duty. Mean time to return to work ranged from 8.69 - 34.8 weeks after surgery. Four studies also reported return to sport, which ranged from 60.9% to 100%. Mean time for returning to sport varied between 10.0 - 35.2 weeks after Latarjet procedure. CONCLUSION Patients with anterior shoulder instability who undergo arthroscopic or open Latarjet procedure can expect high rates of return to work and sport. All studies reported return to work rates over 89% with 89.1% of military members were able to return to duty. LEVEL OF EVIDENCE IV, systematic review of level III and Level IV studies.

[PMID: 38357440 PMCID: PMC10862392 DOI: 10.1016/j.jor.2024.01.012] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/22/2023] [Revised: 01/20/2024] [Accepted: 01/22/2024] [Indexed: 02/16/2024] Open
Abstract
Background Severe bipolar bone loss (BBL) represents one of the toughest challenges when managing the instability of glenohumeral joints among athletes and more specifically the ones involved in overhead sports. It refers to the significant loss of the humeral head and the glenoid bone, with an increased risk of failure. The present study aimed to evaluate the functional outcomes of a combined open Latarjet and arthroscopic remplissage in such high-risk individuals. Methods A retrospective evaluation was carried out among athletes with antero-inferior loss of glenoid bone of more than 15 % and large off-track Hill-Sachs defect who underwent the Latarjet technique with iliac crest bone graft (ICBG) harvest used in combination with arthroscopic remplissage between 2021 and 2023. The University of California, Los Angeles (UCLA) score, constant-Murley score (CMS), and the range of motion (ROM; measured as forward flexion, external rotation, and abduction) were evaluated pre-operative and post-operative at the timepoint of 3-month, 6-month, and 1-year. Pre-operative magnetic resonance imaging scans (MRI) and computed tomography scans (CT) were obtained among the patients with severe glenohumeral BBL, and the glenoid track was calculated to identify on-track and off-track Hill-Sachs lesions. Post-operative MRI with filled Hill-Sachs defect post remplissage procedure and 3D CT scan was also done at 6-month to evaluate the union of the ICBG to the native glenoid bone. Results Overall, 11 patients underwent for the combined procedure for severe BBL. The UCLA score (31.18 ± 3.74), and the CMS (93.64 ± 8.38) at the time-point of 1-year post-operatively showed remarkable improvement in comparison with the preoperative scores (P < 0.0001); and the ROM including abduction, external rotation, and forward flexion were restored to near normality. All patients showed bony union at 6-month as confirmed by post-operative CT scan. No complications such as redislocation or subluxation were observed over 1-year. There were no neurological complications or complications related to graft (graft migration or graft breakage or resorption) as well. All the athletes returned to sports activities at an average duration of 6.8-month post-operatively, with 73 % returning to sports at the level of pre-injury. Conclusion The combined procedure of ICBG Latarjet and arthroscopic remplissage for the treatment of severe BBL in athletes achieved satisfactory outcomes over 1-year, with all athletes returning to sports activities.

ANNALS OF JOINT 2024; 9:16. [PMID: 38694813 PMCID: PMC11061656 DOI: 10.21037/aoj-23-46] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/31/2023] [Accepted: 02/04/2024] [Indexed: 05/04/2024]
Abstract
Background and Objective Anterior shoulder dislocations can result in acute glenoid rim fractures that compromise the bony stability of the glenohumeral joint. Adequate fixation of these fractures is required to restore stability, decrease shoulder pain, and facilitate return to activity. The double-row suture bridge is a relatively novel fixation technique, first described in 2009, that accomplishes internal fixation with sufficient stability using an all-arthroscopic technique to restore the glenoid footprint. A 40-year-old female with recurrent anterior shoulder instability in the setting of seizure disorder was found to have a bony Bankart lesion of 25% to 30% with a concomitant superior labral tear. The patient was treated with a double-row bony Bankart bridge and labral repair. At six months follow-up, she has progressed to a full recovery with no recurrence. Methods A search was conducted in May 2023 in PubMed, EMBASE, and CINAHL with the search terms bony Bankart, bone Bankart, osseous Bankart, acute, bridge, suture bridge, double row. Key Content and Findings Double-row suture bridge repairs result in improvement in shoulder function as determined by ASES (93.5), QuickDASH (4.5), SANE (95.9), and SF-12 (55.6). The overall recurrence rate of anterior instability after a bony Bankart bridge repair is 8%. When examining the return to prior level of function, 81.4% of patients were able to do so with only 7.9% of patients reporting significant modifications to their activity level. In mid-term results, double row suture bridge demonstrates similar outcomes to other all-arthroscopic fixation methods of bony Bankart injuries. Importantly, bony Bankart bridge remains a viable option for critical glenoid lesions over the 20% cutoff used in other all arthroscopic techniques. Biomechanically, the double-row suture bridge offers distinct benefits over its single-row counterpart including increased compression, reduced displacement, and reduced step-off. Conclusions Although there is limited data, the studies discussed and the demonstrative case show the potential benefit of all-arthroscopic double-row suture bridge fixation including increased compression, decreased displacement, and a lower complication rate in patients with large bony Bankart lesions traditionally requiring bony augmentation. However, more robust studies are necessary to determine the long-term success of the double-row suture bridge.

Abstract
PURPOSE To compare the accuracy of 3-dimensional (3D) magnetic resonance imaging (MRI) with that of 3D computed tomography (CT) in evaluating glenoid bone loss (GBL). METHODS This review aligned with Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines. PubMed, the Cochrane Library, Embase, and Web of Science were obtained from data inception to August 28, 2023. The search term "glenoid bone loss" was extracted and analyzed via stringent inclusion and exclusion criteria. The Quality Assessment of Diagnostic Accuracy Studies (QUADAS)-2 combined with the QUADAS-Comparative to assess the heterogeneity of included studies. RESULTS A total of 1,589 related studies were retrieved, and 10 studies were finally included, of which a total of 143 shoulders were evaluated. The index test in QUADAS-Comparative was low risk in 9 studies. 3D MRI measurements of GBL were primarily best-fit circles (n = 9). In both clinical and cadaveric studies, the mean percentages of GBL measured by 3D MRI were 0.38% to 2.19% and 0.25% to 6.1% when compared with 3D CT and standard reference values, respectively. Intraclass correlation coefficient agreement greater than 0.9 between GBL percentages measured by 3D CT and 3D MRI. 3D MRI also could accurately measure glenoid width, glenoid height, humeral head width, and height. 3D MRI reconstruction time was similar to that of 3D CT, which was mainly 10 to 15 minutes. CONCLUSIONS In both clinical and cadaveric studies, compared with 3D CT, 3D MRI is accurate and consistent in assessing glenohumeral bone, especially in measuring GBL, and the reconstruction time of 3D MRI is similar to 3D CT. LEVEL OF EVIDENCE Level Ⅲ, systematic review of Level Ⅱ-Ⅲ studies.

Abstract
PURPOSE To assess the quality and level of evidence of studies reporting on Bankart repair for anterior shoulder instability. METHODS A search was performed using the PubMed/Medline database for all studies that reported clinical outcomes on Bankart repair for anterior shoulder instability. The search term "Bankart repair" with all results were analyzed via strict inclusion and exclusion criteria. Two independent investigators scored each included study based on the 10 criteria of the Modified Coleman Methodology Score (CMS) out of 100 and gave each study a score out of 25 based on the Anterior Shoulder Instability (ASI) Methodology criteria. RESULTS Two hundred sixty-six studies were included in the analysis and encompassed a total of 19,156 patients and 19,317 surgical procedures for Bankart repair for shoulder instability. Overall, 81.6% of studies were Level III or IV evidence. The mean CMS score for the studies was 55.3 out of 100, and the mean ASI Methodology score for the studies was 12.1 out of 25. Weaknesses in the studies were identified in sample size, description of preoperative investigations and diagnoses, reporting of mean glenoid bone loss, nonsubjective clinical outcome reporting, and description of associated pathologies. CONCLUSIONS A large proportion of studies reporting the clinical outcomes of Bankart repair for anterior shoulder instability are of low methodological quality and have a low level of evidence. CLINICAL RELEVANCE This study emphasizes need for greater reporting of many variables such as body mass index, mean glenoid bone loss, and patient-reported outcomes and provides a framework for future studies reporting.

Magnetic Resonance Imaging Analysis Demonstrates Improved Reliability in Measuring Shoulder Glenoid Bone Loss Using a Two-Thirds Glenoid Height Technique Compared to the "Best-fit Circle". Arthroscopy 2024; 40:666-671. [PMID: 37419223 DOI: 10.1016/j.arthro.2023.06.048] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/24/2023] [Revised: 06/22/2023] [Accepted: 06/23/2023] [Indexed: 07/09/2023]
Abstract
PURPOSE To evaluate the superior to inferior glenoid height as a reliable reference in best-fit circle creation for glenoid anatomy. METHODS The morphology of the native glenoid was evaluated using magnetic resonance imaging (MRI) in patients without shoulder instability. Using T1 sagittal MRI images, 2 reviewers independently estimated glenoid size using the two-thirds technique and the "best-fit circle" technique at 2 different times. A Student t-test was used to determine significant difference between the two methodologies. Inter- and intra-rater reliability were calculated using interclass and intraclass coefficients. RESULTS This study included 112 patients. Using the results of glenoid height and "best-fit circle" diameter, the diameter of the "best-fit circle" was found to intersect the glenoid line at 67.8% of the glenoid height on average. We found no significant difference between the 2 measures of glenoid diameter (27.6 vs 27.9, P = .456). The interclass and intraclass coefficients for the two-third method were 0.85 and 0.88, respectively. The interclass and intraclass coefficients for the perfect circle methods were 0.84 and 0.73, respectively. CONCLUSIONS We determined that the diameter of a circle placed on the inferior glenoid using the "best-fit circle" technique corresponds to 67.8% of the glenoid height. Additionally, we found that constructing a perfect circle using a diameter equal to two-thirds the height of the glenoid may improve intraclass reliability.

Abstract
BACKGROUND The use of a distal tibial allograft (DTA) for reconstruction of a glenoid defect in anterior shoulder instability has grown significantly over the past decade. However, few large-scale clinical studies have investigated the clinical and radiographic outcomes of the DTA procedure. PURPOSE To conduct a systematic review and meta-analysis of clinical studies with data on outcomes and complications in patients who underwent the DTA procedure for recurrent anterior shoulder instability with glenoid bone loss. STUDY DESIGN Systematic review and meta-analysis; Level of evidence, 4. METHODS A comprehensive search of major bibliographic databases was conducted for articles pertaining to the use of a DTA for the management of anterior shoulder instability with associated glenoid bone loss. Postoperative complications and outcomes were extracted and compiled in a meta-analysis. RESULTS Of the 8 included studies with 329 total participants, the mean patient age was 28.1 ± 10.8 years, 192 (83.8%) patients were male, and the mean follow-up was 38.4 ± 20.5 months. The overall complication rate was 7.1%, with hardware complications (3.8%) being the most common. Partial graft resorption was observed in 36.5% of the participants. Recurrent subluxation was reported in 1.2% of the participants, and recurrent dislocation prompting a reoperation was noted in 0.3% of the participants. There were significant improvements in clinical outcomes, including American Shoulder and Elbow Surgeons score (40.9-point increase; P < .01), Single Assessment Numeric Evaluation (47.2-point increase; P < .01), Western Ontario Shoulder Instability Index (49.4-point decrease; P < .01), Disabilities of the Arm, Shoulder and Hand (20.0-point decrease; P = .03), and visual analog scale (2.1-point decrease; P = .05). Additionally, postoperative shoulder range of motion significantly increased from baseline values. CONCLUSION The DTA procedure was associated with a low complication rate, good clinical outcomes, and improved range of motion among patients with anterior shoulder instability and associated glenoid defects.

Abstract
Studies have shown that glenoid- and humeral-sided bone loss may be present in up to 73-93% of individuals with recurrent anterior shoulder instability. As such, bone loss must be addressed appropriately, as the amount of bone loss drives surgical decision making and influences outcomes. Methods to describe and measure bone loss have changed over time. Originally, glenoid and humeral bone loss were viewed separately. However, the concepts of bipolar bone loss, the glenoid track (GT), and "on/off-track" lesions arose, highlighting the interplay between the two entities in contributing to recurrent instability. Classically, "off-track" lesions have been described as those Hill-Sachs interval (HSI) greater than the GT, and have been shown to result in higher rates of re-instability when addressed nonoperatively or with Bankart repair alone. More recently, further attention has been given to "on-track" lesions (HSI < GT). The new concept of "distance to dislocation" (DTD) has gained popularity. DTD is calculated as the difference between the GT and HSI, and literature evaluating DTD suggests that not all "on-track" lesions should be treated in the same manner. The purpose of this concept review article is twofold: (I) describe glenoid, humeral, and bipolar bone loss in the setting of anterior shoulder instability; and (II) elaborate on the new concept of "DTD" and its use in guidance of management.

Abstract
PURPOSE Estimation of glenoid bone loss in CT scans following shoulder dislocation is required to determine the type of surgery needed to restore shoulder stability. This paper presents a novel automatic method for the computation of glenoid bone loss in CT scans. METHODS The model-based method is a pipeline that consists of four steps: (1) computation of an oblique plane in the CT scan that best matches the glenoid face orientation; (2) selection of the glenoid oblique CT slice; (3) computation of the circle that best fits the posteroinferior glenoid contour; (4) quantification of the glenoid bone loss. The best-fit circle is computed with newly defined Glenoid Clock Circle Constraints. RESULTS The pipeline and each of its steps were evaluated on 51 shoulder CT scans (44 patients). Ground truth oblique slice, best-fit circle, and glenoid bone loss measurements were obtained manually from three clinicians. The full pipeline yielded a mean absolute error (%) for the bone loss deficiency of 2.3 ± 2.9 mm (4.67 ± 3.32%). The mean oblique CT slice selection difference was 1.42 ± 1.32 slices, above the observer variability of 1.74 ± 1.82 slices. The glenoid bone loss deficiency measure (%) on the ground truth oblique glenoid CT slice has a mean average error of 0.54 ± 1.03 mm (4.76 ± 3.00%), close to the observer variability of 0.93 ± 1.40 mm (2.98 ± 4.97%). CONCLUSION Our pipeline is the first fully automatic method for the quantitative analysis of glenoid bone loss in CT scans. The computed glenoid bone loss report may assist orthopedists in selecting and planning surgical shoulder dislocation procedures.

[PMID: 37352999 DOI: 10.1016/j.jse.2023.05.022] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/29/2022] [Revised: 04/21/2023] [Accepted: 05/07/2023] [Indexed: 06/25/2023]
Abstract
BACKGROUND Deciding how many anchors to use in a Bankart repair is challenging because of the desire to enhance stability while avoiding a postage-stamp fracture of the glenoid rim. METHODS This controlled laboratory study investigated load to fracture of the anterior glenoid rim after drilling holes of varying number and diameter and inserting anchors of 2 different types and sizes, with and without perforation of the medial cortex of the glenoid, creating postage-stamp fractures using a metallic humeral head that was compressed against the anterior glenoid rim. A destructive model with a servohydraulic load frame was used to test 46 synthetic scapulae with compressive strength and elastic modulus similar to that of a human glenoid. Load to fracture of the intact glenoid was compared with groups with a varying number of anchor holes of different diameters, with anchors of different sizes and types, and with anchors perforating or not perforating the glenoid medial cortex. The percentage of force to fracture an intact specimen was used to identify relative risk of fracture: low risk >75%, moderate risk 75%-50%, and high risk <50% of intact load. RESULTS The load to fracture of intact glenoids was 1276 ± 42 N. Loads decreased linearly as the number of holes drilled on the glenoid rim increased. Compared with the 1.6-mm group, the 3.0-mm group had significantly lower glenoid rim strength in specimens with 4, 5, and 7 holes (P = .013, .032, and .045, respectively). All-suture anchors in 1.6-mm holes did not alter the glenoid rim strength, and up to 5 anchors were associated with low risk of fracture. Load to fracture was significantly higher with 3.0-mm rigid core bioabsorbable anchors with 4 anchors (1081 ± 6 N) compared with the 4-hole condition (838 ± 107 N; P = .033). Perforating the glenoid medial cortex with five 1.6-mm anchors significantly weakened the glenoid rim to 58% of intact (P = .012). Perforating the medial cortex weakened the glenoid rim to 52% and 42% (P < .001 for both) of intact in the 3.0-mm 4-anchor and 5-anchor constructions, constituting moderate and high risk of fracture, respectively. CONCLUSION Up to five 1.6-mm all-suture anchors and four 3.0-mm bioabsorbable rigid-core anchors were associated with low risk of fracture of the glenoid rim. Smaller diameter all-suture anchors best preserved structural integrity of the glenoid rim, whereas tunnel enlargement and perforation of the glenoid medial cortex were associated with moderate or high risk of a postage-stamp fracture.

[PMID: 37840899 PMCID: PMC10571685 DOI: 10.1177/23259671231186429] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/28/2023] [Accepted: 04/11/2023] [Indexed: 10/17/2023] Open
Abstract
Background Glenohumeral dislocations often lead to glenoid bone loss and recurrent instability, warranting bony augmentation. While numerous biomechanical studies have investigated fixation methods to secure a graft to the glenoid, a review of available constructs has yet to be performed. Purpose To synthesize the literature and compare the biomechanics of screw and suture button constructs for anterior glenoid bony augmentation. Study Design Systematic review. Methods A systematic review was conducted in accordance with the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. There were 2 independent reviewers who performed a literature search using the PubMed, Embase, and Google Scholar databases of studies published between 1950 and 2020. Studies were included that compared the biomechanical outcomes of fixation for the treatment of anterior shoulder instability with glenoid bone loss. Results Overall, 13 of the 363 studies screened met the inclusion criteria. The included studies measured the biomechanical strength of screws or suture buttons on a cadaveric or synthetic Latarjet construct. Screws and suture buttons were biomechanically similar, as both constructs exhibited comparable loads at failure and final displacement. Screw type (diameter, threading, or composition) did not significantly affect construct strength, and double-screw fixation was superior to single-screw fixation. Additionally, 2 screws augmented with a small plate had a higher load at failure than screws that were not augmented. Unicortical double-screw fixation was inferior to bicortical double-screw fixation, although construct strength did not significantly decrease if 1 of these screws was unicortical. Further, 2 screws inserted at 15° off axis experienced significantly higher graft displacement and lower ultimate failure loads than those inserted at 0° parallel to the glenoid. Conclusion Suture buttons provided comparable strength to screws and offer an effective alternative to reduce screw-related complications. Augmentation with a small plate may clinically enhance construct strength and decrease complications through the dispersion of force loads over a greater surface area. Differences in screw type did not appear to alter construct strength, provided that screws were placed parallel to the articular surface and were bicortical.

Abstract
BACKGROUND The primary aim of this study was to investigate bone loss in the glenoid with magnetic resonance imaging in posterior shoulder instability with only a labral tear. METHODS A total of 76 patients operated on because of posterior and anteroposterior shoulder instability only with a labral tear between 2006 and 2019 (n = 40 and n = 36, respectively) were included in this study. The instability type, a presence of an additional superior labrum anteroposterior (SLAP) lesion, the number of dislocations, and the magnetic resonance imaging-based measurements (the glenoid diameter and the bone defect size in the glenoid, the Hill-Sachs lesion [HSL] and the reverse HSL [rHSL] length, the angle and the arc length of HSL and rHSL, and the humerus head diameter and its area) were analyzed. RESULTS The size of the anterior glenoid defect, the rHSL measurements (length, angle, and arc length), and the ratio of the anterior glenoid defect size to the glenoid diameter were significantly higher for anteroposterior instability (P < .01) cases. There was no significant difference (P = .49, .64, and .82, respectively) for the presence of an additional SLAP pathology, the glenoid diameter, the posterior glenoid defect, and the ratio of the posterior glenoid defect size to the glenoid diameter in posterior and anteroposterior instability groups. The increased number of dislocations was associated with increased rHSL length and total arc length (P = .04 and .03, respectively). An additional SLAP lesion in posterior shoulder instabilities was not associated with the bone defect size (P = .29). CONCLUSION Although the posterior shoulder instability with only a labral tear is likely to cause a bone defect, we have shown that the instability is not expected to be caused by the bone defect. Therefore, this study points out that only soft tissue repair without considering the bone defect could be promising in this patient group.

Abstract
BACKGROUND Reconstruction techniques for anterior glenoid bone loss have seen a trend from screws to suture-based fixations. However, comparative biomechanical data, including primary fixation and glenoid-graft contact pressure mapping, are limited. HYPOTHESIS Suture-based bone block cerclage (BBC) and suspensory suture button (SB) techniques provide similar primary fixation and cyclic stability to double-screw fixation but with higher contact loading at the bony interface. STUDY DESIGN Controlled laboratory study. METHODS In total, 60 cadaveric scapulae were prepared to simulate anterior glenoid bone loss with coracoid autograft reconstruction. Graft fixation was performed with 3 different techniques: (1) an interconnected all-suture BBC, (2) 2 SB suspensions, and (3) 2 screws. Initial compression was analyzed during primary fixation. Cyclic peak loading with 50 N and 100 N over 250 cycles at 1 Hz was performed with a constant valley load of 25 N. Optical recording and pressure foils allowed for spatial bone block tracking and contact pressure mapping at the glenoid-graft interface. Load-to-failure testing was performed at a rate of 1.5 mm/s with ultimate load and stiffness measured. RESULTS Initial graft compression was higher with screw fixation (141 ± 5 N) compared with suture-based fixations (P < .001), with BBC fixation providing significantly higher compression than SB fixation (116 ± 7 N vs. 91 ± 5 N; P < .001). Spatial bone block migration and ultimate failure load were similar between the BBC and screw groups. The SB group showed significantly increased bone block translation (3.1 ± 1.0 mm; P≤ .014) and rotation (2.5°± 1.4°; P≤ .025) and significantly lower ultimate failure load (180 ± 53 N) compared with the BBC (P = .046) and screw (P = .002) groups. Both suture-based fixations provided significantly increased graft-glenoid contact loading with higher pressure amplitudes (P≤ .032) and contact pressure after cyclic loading (+13%; SB: P = .007; BBC: P = .004) compared with screw fixation. CONCLUSION Both SB and interconnected cerclage fixation improved dynamic contact loading compared with screw fixation in a biomechanical glenoid bone loss model. Cerclage fixation was biomechanically comparable with screw fixation but with a greater variability. SB fixation showed significantly lower primary fixation strength and greater bone block rotation and migration. CLINICAL RELEVANCE Suture-based bone block fixations improved graft-glenoid contact loading, but the overall clinical consequence on healing remains unclear.

Abstract
Glenohumeral bone loss is frequently observed in cases of recurrent anterior and posterior shoulder instability and represents a risk factor for failure of nonoperative treatment. Patients with suspected glenoid or humeral bone loss in the setting of recurrent instability should be evaluated with a thorough history and physical examination, as well as advanced imaging including computed tomography (CT) and/or magnetic resonance imaging (MRI). In cases of both anterior and posterior instability, the magnitude and location of bone loss should be determined, as well as the relationship between the glenoid track (GT) and any humeral defects. While the degree and pattern of osseous deficiency help guide treatment, patient-specific risk factors for recurrent instability must also be considered when determining patient management. Treatment options for subcritical anterior bone loss include labral repair and capsular plication, while more severe deficiency should prompt consideration of bony augmentation including coracoid transfer or free bone block procedures. Concomitant humeral lesions are treated according to the degree of engagement with the glenoid rim and may be addressed with soft tissue remplissage or bony augmentation procedures. While critical and subcritical thresholds of glenoid bone loss guide the management of anterior instability, such thresholds are less defined in the setting of posterior instability. Furthermore, current treatment algorithms are limited by a lack of long-term comparative studies. Future high-quality studies as well as possible modifications in indications and surgical technique are required to elucidate the optimal treatment of anterior, posterior, and bipolar glenohumeral bone loss in the setting of recurrent shoulder instability.

Abstract
Introduction There is a trend towards arthroscopically treating shoulder instability with glenoid deficiency. Despite this, there remains the option for treatment through an open technique. Multiple bone augmentation options are available for recurrent anterior shoulder instability. Objective To provide a systematic review of recent studies for recurrent anterior shoulder instability necessitating glenoid bone augmentation specifically through open procedures using coracoid bone or free bone blocks [iliac crest bone autograft/allograft or distal tibia allograft (DTA)]. Methods PubMed, Cochrane, EMBASE, and Google Scholar were searched for studies reporting open glenoid bone augmentation procedures with iliac crest, tibia, or coracoid bones within 10 years. Extracted data included study/patient characteristics, techniques, prior surgeries, prior dislocations, radiographic findings, range of motion (ROM), recurrent instability, patient-reported outcomes, and complications. Results 92 met inclusion criteria (5693 total patients). Six were studies of iliac crest bone, four of DTA, and 84 using the coracoid bone. 29 studies measured postoperative arthritis showing no development or mild arthritis. 26 studies reported postoperative graft position. 62 studies reported ROM noting decline in internal/external rotation. 87 studies measured postoperative instability with low rates. Rowe Scores with noted improvement across 31/59 (52.5%) studies were seen. Common post operative complications included infection, hematoma, graft fracture, nerve injury, pain, and screw-related irritation. Conclusion Despite a trend towards arthroscopic management of recurrent anterior shoulder instability with glenoid deficiency, open procedures continue to provide satisfactory outcomes. Additionally, studies have demonstrated safe and efficacious use of free bone block graft options in the primary and revision setting.

Abstract
PURPOSE The purpose of this study was to compare glenohumeral stability following a Latarjet, a free bone block (FBB), and a FBB with remplissage for bipolar bone loss. METHODS Nine matched pairs of fresh frozen cadavers were tested in a custom biomechanical apparatus with rotation and progressive translational loading. The free bone block group consisted of a distal tibial allograft with an all-suture tape construct. The Latarjet group was performed with the native coracoid and two partially threaded cannulated screws. A bipolar bone loss model was created with 20% glenoid bone loss and an off-track Hill-Sachs lesion. Testing conditions included the 1) native state, 2) bipolar bone loss model, 3) Latarjet, 4) FBB with distal tibial allograft secured with cerclage sutures, and 5) FBB with remplissage. Each condition was tested for translation, humeral head apex shift, stiffness, and dislocation force. RESULTS There were no differences in translation, stiffness, or dislocation forced between the FBB alone and Latarjet groups. The FBB with remplissage group demonstrated the lowest anterior-inferior translation at 90° of ER, which was statistically significant compared to Latarjet 20N (P = .013) and compared to the FBB alone at 40N (P = .024) and 50N (P = .011). The FBB with remplissage group was significantly stiffer compared to FBB alone at 90° ER with approximately 60% change in stiffness (P = .028). The force required to dislocate the humeral head after treatment was highest in the FBB with remplissage group, which was statistically significant compared to the FBB alone (P = .003) and Latarjet groups (P = .018). CONCLUSION The addition of remplissage to a FBB restores translation and stiffness closer to the intact state compared to a FBB alone or Latarjet in a bipolar bone loss model with an off-track Hill-Sachs lesion. In this model, dislocation force significantly increased with the addition of remplissage to the FBB. CLINICAL RELEVANCE This biomechanical study provides evidence that Latarjet and FBB are both acceptable forms of treatment for bipolar bone loss, but stability can be enhanced with the addition of remplissage following glenoid reconstruction.

Abstract
BACKGROUND The Latarjet procedure is one of the most well-established treatment options for anterior shoulder instability. However, meaningful clinical outcomes after this surgery have not been defined. PURPOSE This study aimed to establish the minimal clinically important difference (MCID) and Patient Acceptable Symptom State (PASS) for commonly used outcome measures in patients undergoing the Latarjet procedure and determine correlations between preoperative patient characteristics and achievement of MCID or PASS. STUDY DESIGN Case series; Level of evidence, 4. METHODS A multicenter retrospective review at 4 institutions was performed to identify patients undergoing primary open Latarjet procedure with minimum 2-year follow-up. Data collected included patient characteristics (age, sex, sports participation), radiological parameters (glenoid bone loss, off-track Hill-Sachs lesion), and 4 patient-reported outcome measures (collected preoperatively and 2 years postoperatively): the American Shoulder and Elbow Surgeons (ASES) score, the Single Assessment Numeric Evaluation (SANE), the visual analog scale (VAS) for pain, and the Western Ontario Shoulder Instability Index (WOSI). The MCID and PASS for each outcome measure were calculated, and Pearson and Spearman coefficient analyses were used to identify correlations between MCID or PASS and preoperative variables (age, sex, sports participation, glenoid bone loss, off-track Hill-Sachs lesion). RESULTS A total of 156 patients were included in the study. The MCID values for ASES, SANE, VAS pain, and WOSI were calculated to be 9.6, 12.4, 1.7, and 254.9, respectively. The PASS values for ASES, SANE, VAS pain, and WOSI were 86.0, 82.5, 2.5, and 571.0, respectively. The rates of patients achieving MCID were 61.1% for VAS pain, 71.6% for ASES, 74.1% for SANE, and 84.2% for WOSI. The rates of achieving PASS ranged from 78.4% for WOSI to 84.0% for VAS pain. There was no correlation between any of the studied preoperative variables and the likelihood of achieving MCID or PASS. CONCLUSION This study defined MCID and PASS values for 4 commonly used outcome measures in patients undergoing the Latarjet procedure. These findings are essential for incorporating patient perspectives into the clinical effectiveness of the Latarjet procedure and provide valuable parameters for the design and interpretation of future clinical trials.

[PMID: 34988628 DOI: 10.1007/s00256-021-03981-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/14/2021] [Revised: 10/25/2021] [Accepted: 12/19/2021] [Indexed: 02/02/2023]
Abstract
OBJECTIVE Glenoid bone loss is estimated using a best-fit circle method and requires software tools that may not be available. Our hypothesis is that a vertical reference line drawn parallel to the long axis of the glenoid and passing through the inflection point of the coracoid and glenoid will represent a demarcation line of approximately 20% of the glenoid. Our aim is to establish a more efficient method to estimate a surgical threshold for glenoid insufficiency. METHODS Fifty patients with normal glenoid anatomy were randomly chosen from an orthopedic surgeon's database. Two orthopedic surgeons utilized T1-weighted sagittal MRIs and the coracoglenoid line technique to determine the percentage of bony glenoid anterior to vertical line. Two musculoskeletal radiologists measured the same 50 glenoids using the circle technique. Differences were determined using dependent t test. Reliability was compared using interclass correlation coefficient and Kappa. Validity was compared using Pearson correlation coefficient. RESULTS Mean surface area of the glenoid anterior to the vertical line was on average 21.69% ± 3.12%. Surface area of the glenoid using the circle method was on average 20.86% ± 2.29%. Inter-rater reliability of the circle method was 0.553 (fair). Inter-rater reliability of the vertical line technique was 0.83 (excellent). There was a linear relationship between circle and vertical line measurements, r = 0.704 (moderate to high). CONCLUSION The coracoglenoid line appears to represent a line of demarcation of approximately 21% of glenoid bone anterior to the coracoglenoid line. Our technique was found to be reliable, valid, and accurate.

Implant-free iliac crest bone graft procedure shows anatomic remodelling without redislocation in recurrent anterior shoulder instability after short-term follow-up. Arch Orthop Trauma Surg 2022; 142:1047-1054. [PMID: 33486557 DOI: 10.1007/s00402-021-03777-4] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/10/2020] [Accepted: 01/06/2021] [Indexed: 10/22/2022]
Abstract
INTRODUCTION With the help of a J-shaped bicortical iliac crest bone graft, the morphology of the glenoid can be augmented without having to use screws to achieve glenohumeral stability. The aim of this retrospective clinical study was to evaluate the clinical stability and function of the shoulder joint as well as the radiological remodelling process and arthropathic outcomes following the J-bone graft technique. MATERIALS AND METHODS 34 patients with recurrent shoulder dislocations and bony glenoid defects were treated with the J-bone graft technique between 2010 and 2018 at our level-I trauma centre. 15 patients (18 shoulders) could be recruited for the study. Pain levels, ASES, UCLA, SST, DASH, Rowe and WOSI Scores were collected using questionnaires. In 13 patients (16 shoulders) the Constant Score, ROM, CT with 3D reconstruction of the glenoid to assess the graft remodelling and X-rays were performed additionally. RESULTS None of the patients suffered subluxations or recurrent dislocations during the follow-up period. The overall complication rate was 11%. The evaluation using objective and subjective shoulder function scores yielded good-to-excellent results. Radiological assessment at follow-up showed a low rate of moderate-to-severe arthritis (12%) and a high rate of shoulders without any signs of arthritic degeneration (53%). The CT scans all revealed an almost complete restoration of the glenoid with none of the grafts being resorbed. A rise in the average glenoid circumference and glenoid area could be demonstrated between preoperative measurements (81.6 and 82.4%, respectively) and follow-up measurements (104 and 102.5%, respectively). CONCLUSION The results of this study show a successful stabilisation of the shoulder joint and a low complication rate following the J-bone graft technique. Remodelling of the bone graft could be demonstrated, which in turn led to an almost perfect glenoid surface area of 100%.

Abstract
Recurrent shoulder instability with glenoid bone deficiency remains an increasing risk for failed shoulder stabilization surgery. Numerous free bone block procedures for primary treatment of anterior shoulder stability have been introduced as an alternative for the Latarjet procedure, including both autografts and allografts. Among such options is the fresh distal tibial allograft (DTA), a dense weightbearing bone without donor site morbidity and excellent conformity to the native glenoid. The aim of this Technical Note is therefore to describe our surgical technique for use of fresh DTA as a free bone block choice in the setting of primary anterior glenoid reconstruction in a patient with recurrent shoulder instability.

Abstract
Background Surgical repair for shoulder instability includes arthroscopic Bankart, open Bankart, and Latarjet-Bristow. Methods This is a cohort study of patients who underwent arthroscopic Bankart, open Bankart, or Latarjet-Bristow procedures that were identified within the National Surgical Quality Improvement Program database (2007-2019). Unadjusted and adjusted analyses were performed (α = 0.05). Outcomes included 30-day adverse events, readmission, and operative time. Results This study included 10,955 patients (9128 arthroscopic Bankart, 1148 open Bankart, and 679 Latarjet-Bristow). Compared with arthroscopic Bankart, Latarjet-Bristow had longer operative times (129.96 [95% CI: 126.49-133.43] vs. 86.35 [85.51-87.19] minutes), along with a higher percentage of serious adverse events (2.5% vs. 0.4%), reoperation (1.9% vs. 0.1%), readmission (1.8% vs. 0.3%), thromboembolic complications (0.4% vs. 0.1%), and sepsis (0.4% vs. 0.0%) (P < .05 for all). Open Bankart had longer operative times (98.17 [95.52-100.82] vs. 86.35 [85.51-87.19] minutes) and a higher percentage of sepsis (0.2% vs. 0.0%) (P < .05 both). Latarjet-Bristow had increased odds of a serious adverse event (odds ratio [OR]: 7.68 [4.19-14.07]), reoperation (OR: 17.32 [7.58-39.56]), readmission (OR: 5.73 [2.84-11.54]), and deep wound complications (OR: 14.98 [3.92-57.23]) (P < .05 for all). In comparing the relative utilization of arthroscopic versus open Bankart, arthroscopic Bankart increased (83.4% to 91.2%) while open Bankart decreased (16.6% to 8.8%) from the 2011-2013 time period to 2017-2019 (P trend < .001). Conclusion In addition to a low complication rate, the relative utilization of arthroscopic Bankart increased compared with open Bankart over the past decade. Furthermore, Latarjet-Bristow was associated with a higher incidence of serious adverse events than arthroscopic Bankart.

Abstract
PURPOSE OF REVIEW The aim of this scoping review is to provide an overview of the literature published over the past 5 years related to the management of bone loss in anterior shoulder instability. RECENT FINDINGS During recent years, there has been a focus on patients at high risk for failure following soft tissue anterior stabilization (Bankart repair). A growing body of evidence suggests that anterior capsulolabral repair is insufficient in the setting of subcritical glenoid bone loss with an off-track Hill Sachs lesion. In such cases, the addition of a remplissage procedure to a Bankart repair or a bone-block augmentation to the glenoid (Latarjet, for example) is often advocated to decrease the risk of recurrent instability. Recent studies have also evaluated the role of alternative bone-block procedures in comparison to the Latarjet, outcomes with arthroscopic and open techniques as well as various fixation methods and radiological outcomes (bone graft resorption, glenohumeral osteoarthritis). Advances in our understanding of subcritical glenoid bone loss and the glenoid track concept have significantly impacted clinical decision making and treatment selection. The development of arthroscopic techniques has allowed for minimally invasive and safe arthroscopic bone-block procedures as an alternative to open procedures. Further research related to free bone-block procedures will inform long-term outcomes between these procedures and the gold standard Latarjet. Additionally, high-quality evidence is lacking to identify the ideal treatment for patients with glenoid subcritical glenoid bone defect. Variability in outcome reporting suggests the need to standardize outcome measures for future instability trials.

Abstract
Purpose To compare the outcomes of athletes who have been treated for either primary or recurrent anterior shoulder instability with arthroscopic Bankart repair (ABR). Methods A retrospective review of patients who underwent ABR for anterior shoulder instability, with a minimum of 24 months’ follow-up, was performed. Those who underwent ABR for primary instability were matched in a 1:1 ratio for age, sex, sport, and level of preoperative play to those who underwent ABR for recurrent instability. The rate, level, and timing of return to play (RTP), as well as the Shoulder Instability–Return to Sport After Injury score, were evaluated. Additionally, the recurrence rate, visual analog scale score, Subjective Shoulder Value, Rowe score, satisfaction, and whether patients would undergo the same operation again were compared. Results After analysis of 467 patients, 100 athletes who underwent ABR for primary instability were identified and subsequently pair matched to 100 patients who underwent ABR for recurrent instability, with a mean age of 27.2 years, 87% male patients, 68% collision athletes, and a mean follow-up period of 61.9 months. There was no significant difference between the groups in the rate of RTP (80% vs 79%, P = .86) or RTP at the preinjury level (65% vs 65%, P >. 999); however, there was a significant difference in time to RTP (6.9 ± 2.9 months vs 5.9 ± 2.5 months, P = .02). There were no significant differences in visual analog scale score, Shoulder Instability–Return to Sport After Injury score, Subjective Shoulder Value, Rowe score, patient satisfaction, and whether patients would undergo the operation again (P > .05 for all). There was no difference in the rate of recurrent instability after ABR (10% vs 16%, P = .29). Conclusions ABR results in excellent clinical outcomes, high rates of RTP, and low recurrence rates for both athletes with primary instability and those with recurrent instability. Level of Evidence Level III, retrospective comparative cohort study.

Abstract
Background: Few studies have compared clinical outcomes between the traditional Latarjet procedure for anterior shoulder instability and the congruent arc modification to the Latarjet procedure. Purpose: To systematically evaluate the literature for the incidence of recurrent instability, clinical outcomes, radiographic findings, and complications for the traditional Latarjet procedure and the congruent arc modification and to compare results of each search. Study Design: Systematic review; Level of evidence, 4. Methods: A systematic review and meta-analysis was conducted according to the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. We included studies published between January 1990 and October 2020 that described clinical outcomes of the traditional Latarjet and the congruent arc modification with a follow-up range of 2 to 10 years. The difference in surgical technique was analyzed using a chi-square test for categorical variables, while continuous variables were evaluated using a Student t test. Results: In total, 26 studies met the inclusion criteria: 20 studies describing the traditional Latarjet procedure in 1412 shoulders, and 6 studies describing the congruent arc modification in 289 shoulders. No difference between procedures was found regarding patient age at surgery, follow-up time, Rowe or postoperative visual analog scores, early or late complications, return-to-sport timing, or incidence of improper graft placement or graft fracture. A significantly greater proportion of male patients underwent glenoid augmentation using the congruent arc modification versus traditional Latarjet (P < .001). When comparing outcomes, the traditional Latarjet procedure demonstrated a lower incidence of fibrous union or nonunion (P = .047) and broken, loose, or improperly placed screws (P < .001), and the congruent arc modification demonstrated improved outcomes with regard to overall return to sport (P < .001), return to sport at the same level (P < .001), incidence of subluxation (P = .003) or positive apprehension (P = .002), and revision surgery for recurrent instability (P = .027). Conclusion: Outcomes after the congruent arc modification proved at least equivalent to the traditional Latarjet procedure in terms of recurrent instability and return to sport, although early and late complications were equivalent. The congruent arc procedure may be an acceptable alternative to traditional Latarjet for the treatment of anterior shoulder instability with glenoid bone loss; however, long-term outcomes of this procedure are needed.

Abstract
Orthoregeneration is defined as a solution for orthopaedic conditions that harnesses the benefits of biology to improve healing, reduce pain, improve function, and optimally, provide an environment for tissue regeneration. Options include drugs, surgical intervention, scaffolds, biologics as a product of cells, and physical and electro-magnetic stimuli. The goal of regenerative medicine is to enhance the healing of tissue after musculoskeletal injuries as both isolated treatment and adjunct to surgical management, using novel therapies to improve recovery and outcomes. Various orthopaedic biologics (orthobiologics) have been investigated for the treatment of pathology involving the shoulder including the rotator cuff tendons, glenohumeral articular cartilage, glenoid labrum, the joint capsule, and bone. Promising and established treatment modalities include hyaluronic acid (HA); platelet-rich plasma (PRP) and platelet rich concentrates (PRC); bone marrow aspirate (BMA) comprising mesenchymal stromal cells (MSCs alternatively termed medicinal signaling cells and frequently, misleadingly labelled "mesenchymal stem cells"); MSC harvested from adipose, umbilical, or placental sources; factors including vascular endothelial growth factors (VEGF), basic fibroblast growth factor (FGF), platelet-derived growth factor (PDGF), transforming growth factor-beta (TGFβ), bone morphogenic protein (BMP), and matrix metalloproteinases (MMPs); prolotherapy; pulsed electromagnetic field therapy; microfracture and other marrow-stimulation techniques; biologic resurfacing using acellular dermal allografts, allograft Achilles tendons, allograft lateral menisci, fascia lata autografts, and porcine xenografts; osteochondral autograft or allograft); and autologous chondrocyte implantation (ACI). Studies involving hyaluronic acid, platelet rich plasma, and medicinal signaling cells of various origin tissues have shown mixed results to-date as isolated treatments and as surgical adjuncts. Despite varied results thus far, there is great potential for improved efficacy with refinement of current techniques and translation of burgeoning preclinical work.

Abstract
INTRODUCTION The Latarjet procedure is an attractive surgical option for the management of chronic anterior shoulder instability. The original surgical approach involves the vertical tenotomy of the subscapularis tendon. Alternatively, the subscapularis muscle is split longitudinally and the tendon left attached at the lesser tuberosity. HYPOTHESIS The hypothesis is that the longitudinal split is of functional advantage and may lead to better functional results and earlier return to sports activities compared to the vertical tenotomy. MATERIAL AND METHODS Thirty-two patients were included in this retrospective cohort study. In 14 patients, the subscapularis tendon was vertically incised (group A), whereas in 18 patients, the subscapularis muscle was split longitudinally (group B). Patients were evaluated at 1 year (FU1) and 2 years (FU2) after the Latarjet procedure. Results at follow-up were correlated with patient-specific data and compared with the preoperative status. Primary outcomes were the functional assessment based on Western Ontario Shoulder Instability (WOSI) index and Constant Score (CS) and the assessment of the return to sports activity. Patients' demographics, duration of surgery, and the rate of recurrent dislocations were recorded as secondary variables. RESULTS All patients started their sports activities with a mean±SD of 12.41±1.24 weeks. Interestingly, the time from surgery to full recovery of sports activities was significantly longer for group A (mean±SD of 30.17±10.36 weeks) compared to group B (mean±SD of 20.71±3.67 weeks). There is a statistically significant decrease of the WOSI score from the preoperative level compared to FU1 and FU2, indicating a decrease in instability related symptoms during the entire follow up period with no statistically significant difference between group A and B. There is an increase in shoulder function during the entire follow up period based on the CS. Most interestingly, there is a statistically significant difference between group A and B at FU1, indicating a significantly better shoulder function for group B at the early follow up timepoint (FU1). At the later follow up timepoint (FU2), no difference exists in the individual items. However, a significantly better total CS remains in group B, indicating an overall improved function compared to group A. DISCUSSION/CONCLUSION The longitudinal split of subscapularis muscle is a safe approach which leads to quicker functional recovery and return to sports activity compared to the vertical tenotomy, which is a benefit especially for active individuals. It is therefore recommended as the standard surgical approach. LEVEL OF EVIDENCE III; Retrospective cohort study.

Abstract
Background The investigation of Hill-Sachs and bony Bankart lesions continues to evolve. Patients with large bone lesions can present with a positive apprehension test even at ranges below 45° of abduction and external rotation of the shoulder. Modern concepts, such as glenoid track and quantification of glenoid bone loss, have been increasingly applied to shoulder instability. The objective of this study was to assess the correlation of the glenoid track and glenoid bone loss on the apprehension test conducted at 0°, 45°, and 90° of shoulder abduction. Methods Ninety-four shoulders of 90 patients with anterior glenohumeral instability were retrospectively assessed. The apprehension test was performed at 0°, 45°, and 90° of shoulder abduction. Computed tomography, magnetic resonance imaging, or magnetic resonance arthrogram scans were performed to calculate the glenoid track and glenoid bone loss. A descriptive analysis, an association analysis, and a logistic regression analysis were used in this study. Logistic regression analysis was used to assess the influence of glenoid track and glenoid bone loss when the apprehension test was positive in lower degrees of abduction. Results A positive apprehension test at 0°, 45°, and 90° of abduction revealed significant association with off-track lesions, glenoid bone losses greater than 13.5%, and bipolar bone lesions. Shoulders classified as off-track were 36.4 times more likely to test positive at 0°, 45°, and 90° than on-track shoulders. The logistic regression analysis revealed that the positive apprehension test at 0°, 45°, and 90° of abduction seems to be more influenced by off-track lesions than by glenoid bone loss greater than the 13.5% threshold. Conclusion Shoulders with a positive apprehension test at 0°, 45°, and 90° are significantly associated with off-track lesions, bipolar bone lesions, and glenoid bone losses greater than 13.5%.

Abstract
Background Revision surgery after the Latarjet procedure is a rare and challenging surgical problem, and various bony or capsular procedures have been proposed. This systematic review examines clinical and radiographic outcomes of different procedures for treating persistent pain or recurrent instability after a Latarjet procedure. Methods A systematic review of the literature was performed using the Medline, Cochrane, EMBASE, Google Scholar and Ovid databases with the combined keywords “failed”, “failure”, “revision”, “Latarjet”, “shoulder stabilization” and “shoulder instability” to identify articles published in English that deal with failed Latarjet procedures. Results A total of 11 studies (five retrospective and six case series investigations), all published between 2008 and 2020, fulfilled our inclusion criteria. For the study, 253 patients (254 shoulders, 79.8% male) with a mean age of 29.6 years (range: 16–54 years) were reviewed at an average follow-up of 51.5 months (range: 24–208 months). Conclusions Eden–Hybinette and arthroscopic capsuloplasty are the most popular and safe procedures to treat recurrent instability after a failed Latarjet procedure, and yield reasonable clinical outcomes. A bone graft procedure and capsuloplasty were proposed but there was no clear consensus on their efficacy and indication.

Evaluation and Management of Glenohumeral Instability With Associated Bone Loss: An Expert Consensus Statement Using the Modified Delphi Technique. Arthroscopy 2021; 37:1719-1728.

Abstract
PURPOSE To establish an international expert consensus, using the modified Delphi technique, on the evaluation and management of glenohumeral instability with associated bone loss. METHODS A working group of 6 individuals generated a list of statements related to history and physical examination, imaging and specialized diagnostic tests, bone loss quantification and classification, treatment outcomes and complications, and rehabilitation for the management of glenohumeral instability associated with bone loss to form the basis of an initial survey for rating by a group of experts. The expert group (composed of 22 high-volume glenohumeral instability experts) was surveyed on 3 occasions to establish a consensus on the statements. Items with over 70% agreement and less than 10% disagreement achieved consensus. RESULTS After a total of 3 rounds, 31 statements achieved consensus. Eighty-six percent of the experts agreed that a history of multiple dislocations and failed soft-tissue surgery should raise suspicion about the possibility of an associated bone deficit. Ninety-five percent of the experts agreed that 3-dimensional (3D) computed tomography (CT) is the most accurate diagnostic method to evaluate and quantify bone loss. Eighty-six percent of the experts agreed that any of the available methods to measure glenoid bone deficiency is adequate; however, 91% of the experts thought that an en face view of the glenoid using 3D CT provides the most accurate method. Ninety-five percent of the experts agreed that Hill-Sachs lesions are poorly quantified and classified by current imaging systems. Ninety percent of the experts agreed that in cases with a glenoid bone deficit greater than 20%, glenoid bone graft reconstruction should be performed and any of the available options is valid. There was no consensus among experts on how Hill-Sachs injuries should be managed or on how postoperative rehabilitation should be carried out. CONCLUSIONS The essential statements on which the experts reached consensus included the following: A history of multiple dislocations and failed soft-tissue surgery should make surgeons consider the possibility of an associated bone deficit. Three-dimensional CT is the most accurate diagnostic method to evaluate and quantify bone loss. Although any of the available methods to measure glenoid bone deficiency is adequate, an en face view of the glenoid using 3D CT provides the most accurate method. Hill-Sachs lesions are poorly quantified and classified by current imaging systems. Finally, in cases with a glenoid bone deficit greater than 20%, glenoid bone graft reconstruction should be performed. LEVEL OF EVIDENCE Level V, consensus statement.

Increased Risk of Short-Term Complications and Venous Thromboembolism in Latarjet-Bristow Procedures Compared With Bankart Repairs. Arthroscopy 2021; 37:806-813. [PMID: 33130058 DOI: 10.1016/j.arthro.2020.10.039] [Citation(s) in RCA: 17] [Impact Index Per Article: 5.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/02/2020] [Revised: 10/18/2020] [Accepted: 10/19/2020] [Indexed: 02/07/2023]
Abstract
PURPOSE To (1) determine the rate of surgical complications and venous thromboembolism (VTE) in patients undergoing arthroscopic Bankart repair, open Bankart repair, or Latarjet-Bristow; and (2) assess potential risk factors for surgical complications and VTE in patients undergoing shoulder stabilization procedures. METHODS The NSQIP database was used to identify patients undergoing isolated surgery for shoulder instability from 2005 to 2017. Demographic data were collected and compared. Logistic regression was used to assess the risk factors for developing a postoperative complication, and regression analyses were used to evaluate the odds of postoperative complications between types of surgery. RESULTS We identified 7,233 patients for inclusion. Patients undergoing Latarjet-Bristow were more likely to be male and Black and to report current tobacco use. Overall, there was a low rate of surgical complications (0.4%) and VTE (0.2%). However, patients undergoing Latarjet-Bristow had nearly a 10-fold increase in the risk of surgical complications compared with an arthroscopic or open Bankart repair (1.9% versus 0.2%, P < .001), including deep surgical site infections, return to operating room within 30 days, and symptomatic VTE (deep venous thrombosis rate: arthroscopic Bankart repair, 0.1%; Latarjet-Bristow, 0.8%; P < .001). There were no differences in the odds of developing a surgical complication or VTE between patients undergoing arthroscopic or open Bankart repair. CONCLUSION This study used a nationally representative, widely validated, peer-reviewed database to demonstrate that patients undergoing a Latarjet-Bristow procedure are at significantly higher risk for short-term postoperative complications, including deep surgical site infections, return to the operating room, and symptomatic VTE, than those undergoing Bankart repair. These findings should not discourage surgeons from proceeding with a coracoid transfer procedure when indicated for glenoid deficiencies, but should inform preoperative counseling and help guide perioperative care to optimize patient outcomes.

Abstract
Introduction Shoulder instability injuries are common in sports involving collisions and overhead movements. Arthroscopic Bankart repair and the open Latarjet are two commonly used surgical stabilisation procedures. There is a lack of knowledge surrounding movement strategies, joint loading and muscle strength after each of these procedures. This study will compare: (1) shoulder joint neuromechanics during activities of daily living and an overhead sporting task; (2) shoulder range of motion; (3) shoulder strength; and (4) self-reported shoulder function and health status, between individuals who have undergone an arthroscopic Bankart repair versus open Latarjet. Methods and analysis This is a prospective cohort, single-centre, non-randomised parallel arm study of surgical interventions for athletic shoulder instability injuries. Thirty participants will be recruited. Of these, 20 will have experienced one or more traumatic shoulder instability injuries requiring surgical stabilisation—and will undergo an arthroscopic Bankart repair or open Latarjet procedure. The remaining 10 participants will have no history of shoulder instability injury and act as controls. Participants will undergo baseline testing and be followed up at 3, 6 and 12 months. A two-way (group×time) analysis of variance with repeated measures on one factor (ie, time) will compare each outcome measure between groups across time points. Ethics and dissemination This study was approved by the Barwon Health and Deakin University Human Research Ethics Committees. Outcomes will be disseminated through publications in peer-reviewed journals and presentations at relevant scientific conferences.

Abstract
The key management of glenohumeral osteoarthritis is shoulder arthroplasty which aims to reduce pain and restore full shoulder function: it has increased in recent years. A detailed understanding of the anatomy of the glenoid and humeral head, as well as morphological changes of the glenoid in osteoarthritis, are important factors to consider when deciding on replacement components. This review begins with a brief introduction of the glenohumeral joint itself, and then considers the detailed anatomy of the glenoid fossa and humeral head, both of which are reported to have variable morphology. Several studies have been undertaken to assess various parameters, especially of the glenoid fossa including its shape, height, width, and articular surface area, version and inclination, in an attempt to define a standard classification that can be applied to surgical intervention. Nevertheless, no definitive consensus concerning the classification of these morphologies has been forthcoming, hence the need for this review. Following a consideration of these morphologies, the current state of knowledge regarding glenoid deformity in osteoarthritis, as well as its surgical management, is considered.

Abstract
Objective
To evaluate and compare the glenoid track method in 3D-reconstructed computed tomography (3D-CT) scans with magnetic resonance imaging (MRI) and/or arthro-MRI.
Methods
Forty-four shoulders with clinical and radiographic diagnosis of traumatic anterior instability were assessed using 3D-CT, MRI, and/or arthro-MRI scans. Glenoid track (GT), Hill-Sachs interval (HSI), and glenoid bone loss (GBL) were determined by a radiologist using 3D-CT images, and classified as on-track/off-track. Three surgeons, blinded to the radiologist's evaluation, performed the same determinations using MRI/arthro-MRI. Descriptive analysis, variance analysis, results disagreement analysis, and receiver operating characteristic (ROC) curves were performed.
Results
Results from the 4 examiners were fully consistent in 61.4% of the cases. Magnetic resonance imaging/arthro-MRI diagnosed off-track injuries with 35 to 65% sensitivity and on-track injuries, with 91.67 to 95.83% specificity. Accuracy ranged from 68.1 to 79.5%. The greatest data divergence occurred for off-track injuries diagnosed by MRI/arthro-MRI. The greatest data variability referred to HSI calculation. Higher HSI and GBL values were associated with greater disagreement among examiners. Hill-Sachs interval values were lower at MRI/arthro-MRI when compared to 3D-CT. Agreement between CT and MRI/arthro-MRI for the GT method was only moderate (kappa value, 0.325–0.579).
Conclusion
Magnetic resonance imaging/arthro-MRI showed low accuracy and moderate agreement for the GT method; as such, it should be used with caution by surgeons.

Abstract
BACKGROUND Patients with a greater risk of recurrent instability and inferior clinical outcomes following a primary Latarjet procedure can be preoperatively identified on the basis of clinical, radiographic, and demographic criteria. The purpose of this study was to identify risk factors influencing the rates of recurrent anterior glenohumeral instability and clinical failure following a primary Latarjet procedure. METHODS All patients who underwent a primary Latarjet procedure were prospectively enrolled and evaluated. The Western Ontario Shoulder Instability Index (WOSI) and Single Assessment Numeric Evaluation (SANE) outcome scores were collected at a minimum 5-year follow-up along with evidence of recurrent instability. Recurrent instability (recurrent subluxation or dislocation) was considered as a failure. Clinical failure was defined as a postoperative WOSI score of ≥630 points (≤70% normal) or a SANE score of ≤70 points. RESULTS From 2004 to 2014, 344 patients (358 shoulders) with a mean age of 30.6 years (range, 16 to 68 years) were enrolled and had a mean follow-up time of 75 months (range, 61 to 89 months). The median postoperative WOSI score was 265 points (range, 0 to 1,100 points), and the median SANE score was 88 points (range, 50 to 100 points). Recurrence occurred in 17 shoulders (4.7%), 5 with dislocation and 12 with subluxation; and 28 (8.2%) of 341 shoulders without recurrent instability were clinical failures following a Latarjet procedure. The risk factors for recurrence included atraumatic dislocation (odds ratio [OR], 4.6; p < 0.01) and bilateral instability (OR, 4.0; p = 0.01), whereas the risk factors for clinical failure (WOSI score of ≥630 points or SANE score of ≤70 points) were female sex (OR, 2.8; p < 0.01) and bilateral instability (OR, 4.6; p = 0.01). CONCLUSIONS Outcomes at a mean of >6 years following a primary Latarjet procedure for anterior shoulder instability were very good, with an overall recurrence rate of 4.7%. An additional 8.2% of cases were defined as clinical failures. Patients with an atraumatic mechanism of primary dislocation, bilateral instability, and female sex were identified to be at a greater risk of recurrence or clinical failure. Although additional work is necessary, patients with capsuloligamentous laxity, relatively atraumatic instability history, bilateral instability, and female sex may be preoperatively identified as having a higher risk of treatment failure after a primary Latarjet procedure.

Abstract
BACKGROUND Glenoid bone loss (GBL) has been implicated as a risk factor for failure of arthroscopic anterior glenohumeral instability repair. Although certain amounts of GBL are associated with higher recurrence rates, there are limited studies on successes versus failures in these cohorts. PURPOSE To compare the outcomes of arthroscopic Bankart repair in patients with and without GBL to determine a threshold percentage of GBL that predicts success. STUDY DESIGN Cohort study; Level of evidence, 2. METHODS All consecutive patients who underwent arthroscopic Bankart repair for anterior shoulder instability between 2004 and 2013 were prospectively enrolled. Patients with ≤25% GBL were included. Patients with no GBL were grouped and compared with those having 5% to 25% GBL. Outcomes included Single Assessment Numerical Evaluation, Western Ontario Shoulder Index, and American Shoulder and Elbow Surgeons scores, with evidence of recurrent instability. Patients with and without GBL were statistically compared with respect to outcomes and recurrence rates. RESULTS Of 434 eligible patients, the cases of 405 (45 female, 360 male; mean age, 27.5 years [range, 18-47 years]) were followed for a mean 61 months (range, 48-96 months). There were 189 (46.6%) with no GBL and 216 (53.3%) with GBL; the mean GBL of the latter cohort was 15% (range, 5%-25%). The mean duration of instability symptoms was 7.9 months (range, 1-21 months) and was significantly longer in the GBL group (P < .05). The mean recurrence rate was 14.8%, which was significantly greater in patients presenting with GBL versus those with none (48/216 [22.2%] vs 12/189 [6.3%]; P < .01). Within the GBL group, GBL ≥15%, duration of symptoms >5 months, and younger age (<20 years) were independent risk factors for failure (P < .01). Patients with any GBL had >4-times greater odds of recurrence after arthroscopic stabilization (odds ratio, 4.21; 95% CI, 2.16-8.21). Moreover, patients presenting for arthroscopic Bankart repair with GBL ≥15% had nearly 3-times greater odds of recurrent instability. CONCLUSION GBL ≥15% in an active patient population portends to increased odds of recurrent instability events and inferior clinical outcomes after arthroscopic Bankart repair. Furthermore, nonmodifiable risk factors, such as age (<20 years) and duration of symptoms before presentation (>5 months), significantly affect risk of recurrence and should be key factors when counseling patients on risk of failure and determining the ideal procedure for the individual patient.

Abstract
Since its first description over 30 years ago arthroscopic stabilisation has evolved. With improvements in knowledge, surgical techniques and materials technology, arthroscopic bankart repair has become the most widely used method for treating patients with symptomatic anterior shoulder instability. These procedures are typically performed in a younger, high demand patient population after a primary dislocation or to treat recurrent instability. A thorough clinical evaluation is required in the clinic setting not only to fully understand the injury pattern but also consider patient expectations prior to embarking on surgery. Diagnostic imaging will aid the clinician in determining the soft tissue pathology as well as assessing bone loss, which facilitates surgical decision-making. Selected patients may benefit from adjunctive procedures such as a remplissage for an "engaging" Hill-sachs lesion. This review will focus on the indications, pre-operative considerations, surgical techniques and outcomes of arthroscopic stabilisation.

Abstract
The glenohumeral joint is prone to instability. Patients with instability should have a physical examination. Imaging studies can provide additional information. Classification schemes that into account soft tissue pathology, neuromuscular control, bone loss, and activity level. An arthroscopic Bankart repair is the mainstay for unidirectional instability. Bone block procedures are indicated for patients with bone loss or a failed attempt at stabilization surgery. The arthroscopic Latarjet is a promising option for these patients. For patients with multidirectional instability, prolonged rehabilitation is indicated, followed by capsular plication or inferior capsular shift if instability is unresponsive to physical therapy.

PURPOSE To assess the anthropometric dimensions of the coracoid process and the glenoid articular surface and to determine possible implications with the different commercially available Latarjet fixation techniques. METHODS In a total of 101 skeletal scapulae the glenoid length (GL), the glenoid width (GW), the coracoid length (CL), the coracoid width (CW) and the coracoid thickness (CTh) were measured. In order to assess the ability of the transferred coracoid to restore the glenoid anatomy we created a hypothetical model of 10%, 15%, 20%, 25% and 30% glenoid bone loss. We analyzed four common surgical fixation techniques for the Latarjet procedure (4.5 mm screws, 3.75 mm screws, 3.5 mm screws, and 2.8 mm button). The distances from the superior-inferior and medio-lateral limits of the coracoid using the four different fixation methods were calculated. We hypothesized that the "safe distance" between the implant and the coracoid osteotomy should be at least equal to the diameter of the implant. RESULTS The intra and inter-observer reliability tests were almost perfect for all measurements. The mean GH was 36.8 ± 2.5 mm, the GW 26.4 ± 2.2 mm, the CL 23.9 ± 3 mm, the CW 13.6 ± 2.mm, and the mean CTh was 8.7 ± 1.3 mm. The CL was < 25 mm in 46% of the cases. In cases with 25% and 30% bone loss, the coracoid graft restored the glenoid anatomy in 96% and 79.2% of the cases. With the use of the 4.5 mm screws the "safe distance" was present in 56% of the cases, with the 3.75 mm screws in 85%, with the 3.5 mm screws in 87%, and with the 2.8 mm button in 98% of the cases. The distance from the medio-lateral limit of the coracoid could be significantly increased (up to 9 mm) when smaller-button implants are used. CONCLUSIONS The coracoid graft could not always restore glenoid defects of 30%. Larger implants could be positioned too close to the osteotomy and the "medio-lateral offset" of the coracoid could be increased with smaller implants.

Abstract
BACKGROUND Several measurement techniques have been reported to quantify glenoid bone defect in patients with anterior shoulder instability. Among them, the method that uses a best-fit circle and another that uses the contralateral glenoid as a control are most commonly used. However, to our knowledge, no study has been reported that compared the reliability of these methods. The purpose of this study, therefore, was to determine which of these methods has higher reproducibility. METHOD In this study, 3-dimensional computed tomography data from 94 patients (mean age 29 years) with unilateral anterior shoulder instability were used. Three examiners measured the glenoid bone defect of each patient 3 times using 2 techniques: the best-fit circle method and the contralateral comparison method. Intra- and interobserver reliabilities were measured using intraclass correlation coefficient (ICC). RESULTS The intraobserver reliability was found to be 0.91 for the best-fit circle method and 0.98 for the contralateral comparison method. The interobserver reliability was 0.77 for the best-fit circle method and 0.88 for the contralateral method. The percentage of glenoid defect was 11.5% when using the best-fit circle and 10.7% with the contralateral method. CONCLUSION The contralateral comparison method was more reliable than the best-fit circle method for quantifying the amount of glenoid bone loss.

Abstract
Recurrent instability after anterior shoulder stabilization surgery is not an uncommon complication, with variable rates of recurrences associated with different surgical procedures. The Latarjet procedure continues to be the gold standard in the management of anterior instability with significant glenoid bone loss, although a recent trend toward arthroscopic anatomic glenoid reconstruction (AAGR) with distal tibial allograft has been noted, with excellent short-term results and minimal complication rates. Arthroscopic revision stabilization for failed stabilization procedures is increasingly being performed, although it is technically more challenging than the primary stabilization procedure because of the anatomic rearrangements of the index surgery. In this article, we describe a revision arthroscopic technique for anatomic glenoid reconstruction using iliac crest autograft for a previous failed AAGR procedure secondary to nonunion of the graft. The graft is passed through the Halifax far-medial portal without splitting the subscapularis. Arthroscopic revision in the setting of a failed AAGR procedure is technically easier than after a Latarjet procedure, as the anatomy is relatively undisturbed in the former, facilitating easier identification of anatomic landmarks, accurate graft positioning, and decreased risk of neurovascular injuries. A Bankart capsulolabral repair is performed after graft fixation, making the graft extra-articular and providing additional stability.
