Glenoid bone loss and Hill-Sachs width percentage score are useful to select optimal operation for the treatment of glenohumeral instability in overhead athletes: Arthroscopic Bankart repair with remplissage versus open Latarjet. Knee Surg Sports Traumatol Arthrosc 2024. [PMID: 38932604 DOI: 10.1002/ksa.12333] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/24/2023] [Revised: 05/16/2024] [Accepted: 05/21/2024] [Indexed: 06/28/2024]
Abstract
PURPOSE Glenohumeral instability with combined bone lesion in contact and overhead athletes with subcritical bone loss is challenging to treat with high recurrent instability. Treatment options are arthroscopic Bankart repair with remplissage and Latarjet operations. However, there is no consensus on their effectiveness. This study aims to compare the clinical outcomes and return to sports after both operations and whether evaluating the glenoid bone loss and Hill-Sachs width to calculate the total bone loss can help determine the appropriate operation. METHODS In this retrospective comparative analysis, 30 athletes who underwent index arthroscopic Bankart repair with remplissage (n = 16) or Latarjet procedure (n = 14) between 2017 and 2020 were included. Computed tomography (CT) and magnetic resonance imaging (MRI) were routinely performed. The quick Disabilities of the Arm, Shoulder and Hand (qDASH), American Shoulder and Elbow Surgeons (ASES), instability severity index (ISI) scores and range of motion (ROM) were recorded preoperatively and at a mean follow-up of 53 months (SD = 12). Follow-up included time-to-return sports, self-perceived sports performance level and complications/recurrent dislocations. RESULTS Preoperative qDASH, ASES, ISI scores, ages and genders were similar. The Latarjet group had significantly larger glenoid bone loss, Hill-Sachs width and total bone loss (p < 0.01). Both groups had significant improvement in patient-reported outcomes (PROs) after the operations (p < 0.01). Athletes with a total bone loss <25% underwent arthroscopic Bankart repair with remplissage and total bone loss ≥25% underwent Latarjet procedure, and there were no differences between the groups in terms of postoperative PROs, ROM, time-to-return sports and performance. There were no re-dislocations. CONCLUSION Arthroscopic Bankart repair with remplissage or Latarjet procedure can adequately address glenohumeral instability with combined bone lesions. Patients with total bone loss scores greater than or equal to 25 may particularly benefit from the Latarjet procedure, while the minimally invasive arthroscopic Bankart repair with remplissage can yield equally satisfying scores for total bone loss less than 25. LEVEL OF EVIDENCE Level III.

The Use of Linear Formulas to Estimate Glenoid Bone Loss in the Lebanese Population: A 3-Dimensional Computed Tomography Study. Orthop J Sports Med 2024; 12:23259671241249715.

Abstract
Background Glenoid bone loss (GBL) is common in patients with shoulder instability and plays a major role in surgical decision-making. While a plethora of GBL estimation methods exist, all of which present specific challenges, recent studies have developed simple linear formulas estimating GBL based on glenoid height. Purpose To assess the correlation between glenoid height and width, and to develop specific formulas based on age and sex to calculate the native glenoid width in the Lebanese population. Study Design Cross-sectional study; Level of evidence, 3. Methods Computed tomography scans for 202 normal shoulders were extracted from our database. The glenoids were reconstructed in 3 dimensions and their width and height were measured. Glenoid width and height were compared between male and female groups. Correlation analysis was also performed on the width, height, age, and body mass index. Formulas estimating glenoid width were developed using regression analysis including all variables significantly influencing the model. Results were then compared with the values calculated using previously published formulas to determine the external validity when using linear formulas to estimate GBL. Results Significant differences were found between men and women. Regression analysis found that glenoid height and width strongly influenced the model, and that age showed a weak but significant correlation; therefore, the following 2 sex-specific formulas were developed: width (mm) = 6.1 + 0.51 ×height+ 0.03 ×age, and width (mm) = 4.55 + 0.51 ×height+ 0.03 ×age, in men and women, respectively. The values yielded from the formulas developed in this study and the true width significantly differed from those calculated from previous reports. Conclusion A strong correlation was found between glenoid height and width in a the Lebanese population and demonstrated that glenoid width can be accurately calculated based on the glenoid height and patient's age and sex using the following simplified formulas: width (mm) = 6 + 0.5 ×height+ 0.03 ×age, and width (mm) = 4.5 + 0.5 ×height+ 0.03 ×age, in men and women, respectively.

Abstract
Several surgical procedures have been proposed to address anterior glenohumeral instability, which is one of the most common complaints in the general population. The remplissage, first described in early 2000s, is a procedure performed simultaneously with the arthroscopic Bankart repair to correct large, engaging Hill-Sachs lesions (HSLs). This procedure stabilizes the joint by tenodesing the infraspinatus tendon into the HSL to fill and disengage the defect. This procedure gained popularity because it has relatively low risk and is able to improve shoulder stability while being less invasive than other bone-blocking procedures. The remplissage has become a valuable add-on technique that can substantially improve outcomes in unstable patients undergoing arthroscopic Bankart repair. Nevertheless, several studies in the literature have raised concerns regarding its efficacy in critically unstable patients and the potential range of motion limitations that can arise postoperatively. Additional comparative studies and trials should be conducted to appropriately establish the role of remplissage in treating anterior instability, especially in patients with critical bone loss.

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
Arthroscopic repair of Bankart injury is the first choice for the treatment of anterior shoulder instability. How to avoid recurring shoulder joint dislocation is a challenge, especially when combined with Hill-Sachs lesions. The arthroscopy technology allows for broader vision and less surgical trauma but is limited by a smaller operating space. At present, extensive descriptions about the surgical procedure of arthroscopic Bankart repair have been published. In this Technical Note, we describe the use of remplissage filling with Hill-Sachs lesion combined with Bankart repair to further improve the surgical accuracy and clinical efficacy. In particular, the application of single needle-assisted outside-in remplissage technique and Bankart repair is introduced in detail.

Abstract
Background Accurate measurement of glenoid bone loss (GBL) is critical to preoperative planning in cases of recurrent shoulder instability. The concept of critical bone loss has been established with a value of GBL >13.5% being associated with higher failure rate following arthroscopic Bankart Repair. Advanced imaging, such as magnetic resonance imaging (MRI) scans, can be used to quantify GBL prior to surgery using the best-fit circle technique. Surgeons have traditionally relied on visual inspection of the MRI scan preoperatively or on visual inspection of the glenoid at the time of arthroscopy to determine whether GBL is present. The purpose of this study is to determine if 3 fellowship-trained shoulder surgeons could adequately quantify GBL without using best-fit circle measurements on MRI. Methods A retrospective review was performed which included 122 patients over an 8-year period that had an arthroscopic Bankart repair performed by 3 fellowship-trained surgeons. In all patients, preoperative MRI scans were retrospectively measured using best-fit circle technique to determine true GBL and compare that to the surgeons' preoperative and intraoperative estimation of GBL. Results GBL was correctly identified in only 36% (18/50) of patients when the preoperative best-fit circle measurements were not made. Critical bone loss was missed in 9.8% (12/122) of patients in the study group. The estimated mean bone loss in that group by visual inspection was 11.3% compared to 16% true bone loss measured on MRI. Even in the 18 patients with some identified bone loss prior to surgery, critical bone loss was missed in 6 patients when using visual inspection of the MRI or intraoperative inspection alone. Conclusion Simple visual inspection of glenoid images on MRI scan and visual inspection of the glenoid at the time of surgery are inaccurate in determining the true extent of GBL especially in cases of subtle bone deficiency. Preoperative planning is dependent on the exact degree of bone deficiency and measurement on the MRI scan using the best-fit circle technique is recommended in all cases of instability surgery.

Abstract
BACKGROUND Patients with a history of anterior shoulder instability (ASI) commonly progress to glenohumeral arthritis or even dislocation arthropathy and often require total shoulder arthroplasty (TSA). The purposes of this study were to (1) report patient-reported outcomes (PROs) after TSA in patients with a history of ASI, (2) compare TSA outcomes of patients whose ASI was managed operatively vs. nonoperatively, and (3) report PROs of TSA in patients who previously underwent arthroscopic vs. open ASI management. METHODS Patients were included if they had a history of ASI and had undergone TSA ≥5 years earlier, performed by a single surgeon, between October 2005 and January 2017. The exclusion criteria included prior rotator cuff repair, hemiarthroplasty, or glenohumeral joint infection before the index TSA procedure. Patients were separated into 2 groups: those whose ASI was previously operatively managed and those whose ASI was treated nonoperatively. This was a retrospective review of prospective collected data. Data collected was demographic, surgical and subjective. The PROs used were the American Shoulder and Elbow Surgeons score, Single Assessment Numerical Evaluation score, QuickDASH (Quick Disabilities of the Arm, Shoulder and Hand) score, and 12-item Short Form physical component score. Failure was defined as revision TSA surgery, conversion to reverse TSA, or prosthetic joint infection. Kaplan-Meier survivorship analysis was performed. RESULTS This study included 36 patients (27 men and 9 women) with a mean age of 56.4 years (range, 18.8-72.2 years). Patients in the operative ASI group were younger than those in the nonoperative ASI group (50.6 years vs. 64.0 years, P < .001). Operative ASI patients underwent 10 open and 11 arthroscopic anterior stabilization surgical procedures prior to TSA (mean, 2 procedures; range, 1-4 procedures). TSA failure occurred in 6 of 21 patients with operative ASI (28.6%), whereas no failures occurred in the nonoperative ASI group (P = .03). Follow-up was obtained in 28 of 30 eligible patients (93%) at an average of 7.45 years (range, 5.0-13.6 years). In the collective cohort, the American Shoulder and Elbow Surgeons score, Single Assessment Numerical Evaluation score, QuickDASH (Quick Disabilities of the Arm, Shoulder and Hand) score, and 12-item Short Form physical component score significantly improved, with no differences in the postoperative PROs between the 2 groups. We found no significant differences when comparing PROs between prior open and prior arthroscopic ASI procedures or when comparing the number of prior ASI procedures. Kaplan-Meier analysis demonstrated a 79% 5-year survivorship rate in patients with prior ASI surgery and a 100% survivorship rate in nonoperatively managed ASI patients (P = .030). CONCLUSION At mid-term follow-up, patients with a history of ASI undergoing TSA can expect continued improvement in function compared with preoperative values. However, TSA survivorship is decreased in patients with a history of ASI surgery compared with those without prior surgery.

Abstract
BACKGROUND Wrestling is a physically demanding sport with young athletes prone to traumatic shoulder instability and a paucity of data evaluating the results of shoulder instability surgery (SIS). PURPOSE To assess reoperation rates, patient-reported outcomes, and return to wrestling (RTW) after SIS in a cohort of competitive wrestlers. STUDY DESIGN Case series; Level of evidence, 3. METHODS All competitive wrestlers with a history of shoulder instability and subsequent surgery at a single institution between 1996 and 2020 were identified. All directions of shoulder instability (anterior shoulder instability [ASI], posterior shoulder instability [PSI], and traumatic multidirectional shoulder instability [TMDI]) were analyzed. Exclusions included revision SIS and <2 years of follow-up. Athletes were contacted for determination of complications, RTW, and Western Ontario Shoulder Instability Index scores. RESULTS Ultimately, 104 wrestlers were included with a mean age at initial instability of 16.9 years (range, 12.0-22.7 years), mean age at surgery of 18.9 years (range, 14.0-29.0 years), and a mean follow-up of 5.2 years (range, 2.0-22.0 years). A total of 58 (55.8%) wrestlers were evaluated after a single shoulder instability event, while 46 (44.2%) sustained multiple events before evaluation. ASI was the most common direction (n = 79; 76.0%), followed by PSI (n = 14; 13.5%) and TMDI (n = 11; 10.6%). Surgical treatment was most commonly an arthroscopic soft tissue stabilization (n = 88; 84.6%), with open soft tissue repair (n = 13; 12.5%) and open bony augmentation (n = 3; 2.9%) performed less frequently. RTW occurred in 57.3% of wrestlers at a mean of 9.8 months. Recurrent instability was the most common complication, occurring in 18 (17.3%) wrestlers. Revision SIS was performed in 15 (14.4%) wrestlers. Across the entire cohort, survivorship rates free from recurrent instability and revision surgery were 90.4% and 92.5% at 2 years, 71.9% and 70.7% at 5 years, and 71.9% and 66.5% at 10 years, respectively. Preoperative recurrent instability was an independent risk factor for postoperative recurrent instability (hazard ratio, 3.8; 95% CI, 1.33-11.03; P = .012). CONCLUSION Competitive wrestlers with multiple dislocations before initial clinical evaluation were 3.8 times more likely to experience postoperative recurrent instability. Patients should be counseled that despite SIS, only 57.3% returned to wrestling after surgery.

Abstract
The gleno-humeral joint is by far the most mobile in the human body but also afflicted by dislocations, predominantly anterior. Surgical stabilisation is often successful but failures not uncommon. The following review describes potential causes of failure and highlights the need of adapting surgical methods to pathomorphology.

Abstract
Paediatric and adolescent shoulder instability is caused by a unique combination of traumatic factors, ligamentous laxity, and pattern of muscle contractility. The multifactorial nature of its aetiology makes interpretation of the literature difficult as nomenclature is also highly variable. The purpose of this review is to summarize the existing literature and shed light on the nuances of paediatric and adolescent shoulder instability. The epidemiology, clinical features, imaging, and management of all forms of paediatric shoulder instability are presented. The main findings of this review are that structural abnormalities following a dislocation are uncommon in pre-pubertal paediatric patients. Young post-pubertal adolescents are at the highest risk of failure of non-operative management in the setting of traumatic instability with structural abnormality, and early stabilisation should be considered for these patients. Remplissage and the Latarjet procedure are safe treatment options for adolescents at high risk of recurrence, but the side-effect profile should be carefully considered. Patients who suffer from instability due to generalized ligamentous laxity benefit from a structured, long-term physiotherapy regimen, with surgery in the form of arthroscopic plication as a viable last resort. Those who suffer from a predominantly muscle patterning pathology do not benefit from surgery and require focus on regaining neuromuscular control.

Abstract
BACKGROUND The glenoid track concept for shoulder instability primarily describes the medial-lateral relationship between a Hill-Sachs lesion and the glenoid. However, the Hill-Sachs position in the craniocaudal dimension has not been thoroughly studied. HYPOTHESIS Hill-Sachs lesions with greater inferior extension are associated with increased risk of recurrent instability after primary arthroscopic Bankart repair. STUDY DESIGN Case-control study; Level of evidence, 3. METHODS The authors performed a retrospective analysis of patients with on-track Hill-Sachs lesions who underwent primary arthroscopic Bankart repair (without remplissage) between 2007 and 2019 and had a minimum 2-year follow-up. Recurrent instability was defined as recurrent dislocation or subluxation after the index procedure. The craniocaudal position of the Hill-Sachs lesion was measured against the midhumeral axis on sagittal magnetic resonance imaging (MRI) using either a Hill-Sachs bisecting line through the humeral head center (sagittal midpoint angle [SMA], a measure of Hill-Sachs craniocaudal position) or a line tangent to the inferior Hill-Sachs edge (lower-edge angle [LEA], a measure of Hill-Sachs caudal extension). Univariate and multivariate regression were used to determine the predictive value of both SMA and LEA for recurrent instability. RESULTS In total, 176 patients were included with a mean age of 20.6 years, mean follow-up of 5.9 years, and contact sport participation of 69.3%. Of these patients, 42 (23.9%) experienced recurrent instability (30 dislocations, 12 subluxations) at a mean time of 1.7 years after surgery. Recurrent instability was found to be significantly associated with LEA >90° (ie, Hill-Sachs lesions extending below the humeral head equator), with an OR of 3.29 (P = .022). SMA predicted recurrent instability to a lesser degree (OR, 2.22; P = .052). Post hoc evaluation demonstrated that LEA >90° predicted recurrent dislocations (subset of recurrent instability) with an OR of 4.80 (P = .003). LEA and SMA were found to be collinear with Hill-Sachs interval and distance to dislocation, suggesting that greater LEA and SMA proportionally reflect lesion severity in both the craniocaudal and medial-lateral dimensions. CONCLUSION Inferior extension of an otherwise on-track Hill-Sachs lesion is a highly predictive risk factor for recurrent instability after primary arthroscopic Bankart repair. Evaluation of Hill-Sachs extension below the humeral equator (inferior equatorial extension) on sagittal MRI is a clinically facile screening tool for higher-risk lesions with subcritical glenoid bone loss. This threshold for critical humeral bone loss may inform surgical stratification for procedures such as remplissage or other approaches for at-risk on-track lesions.

Remplissage reduced sense of apprehension and increased the rate of return to sports at preinjury level of elite overhead athletes with on-track anterior shoulder instability. Knee Surg Sports Traumatol Arthrosc 2023; 31:5979-5986. [PMID: 37889321 DOI: 10.1007/s00167-023-07631-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/02/2023] [Accepted: 10/11/2023] [Indexed: 10/28/2023]
Abstract
PURPOSE The purpose of this study was to compare the results of arthroscopic isolated Bankart repair (B) with Bankart repair plus Remplissage (B + R) procedure in contact overhead athletes with on-track anterior shoulder instability. METHODS A total of 64 athletes playing basketball, volleyball and handball in elite professional level who underwent arthroscopic isolated Bankart repair (34 patients) or Bankart repair plus Remplissage procedure (30 patients) with the diagnosis of recurrent anterior shoulder instability between 2017 and 2020, were retrospectively reviewed. Radiologically all patients had on-track Hill-Sachs defects and minimal or subcritical glenoid bone loss (< 13.5%). Patients were evaluated using pre- and postoperative pVAS, SANE, ASES, ROWE, WOSI scores and postoperative active ROM assessment. Patients were also asked for the frequency of any subjective apprehension and satisfaction with the surgery in four grades. RESULTS The mean ages of the groups B and B + R were 26.8 and 26 years (SD = 3.22), respectively; the mean follow-up times were 37.8 and 36.2 months (SD = 11.19). Compared with the preoperative status, there was a statistically significant improvement of all 5 postoperative outcome scores in both groups (P < 0.001). However, significant difference between the improvement of the groups were only found for the SANE (B: 22.3 ± 4.1, B + R: 26.3 ± 4.3; P = 0.0004), ASES (B: 26.1 ± 2.6, B + R: 30.2 ± 3.6; P < 0.001) and ROWE (B: 42 ± 3.7, B + R: 47.7 ± 2.8; P < 0.001) scores in favor of the group B + R. The loss of internal and external rotation of the adducted arm in group B + R was found to be approximately 5 degrees compared to the group B (P < 0.001). More than 80% of group B + R showed no apprehension in sports activities and almost completely returned to pre-injury athletic level, depicting statistically significant improvement compared to group B athletes (P = 0.002 and 0.036, respectively). 3 patients developed re-dislocation after isolated Bankart repair, whereas no re-dislocation occurred in the B + R group. CONCLUSION Adding Remplissage procedure to the Bankart repair provided an advantage in terms of both return to sport at preinjury level and the frequency of apprehension sensation during sports activity. LEVEL OF EVIDENCE III.

Assessment of glenoid bone loss and other osseous shoulder pathologies comparing MR-based CT-like images with conventional CT. Eur Radiol 2023; 33:8617-8626. [PMID: 37453986 PMCID: PMC10667374 DOI: 10.1007/s00330-023-09939-9] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/20/2022] [Revised: 04/24/2023] [Accepted: 05/16/2023] [Indexed: 07/18/2023]
Abstract
OBJECTIVES To evaluate and compare the diagnostic performance of CT-like images based on a 3D T1-weighted spoiled gradient-echo sequence (T1 GRE), an ultra-short echo time sequence (UTE), and a 3D T1-weighted spoiled multi-echo gradient-echo sequence (FRACTURE) with conventional CT in patients with suspected osseous shoulder pathologies. MATERIALS AND METHODS Patients with suspected traumatic dislocation of the shoulder (n = 46, mean age 40 ± 14.5 years, 19 women) were prospectively recruited and received 3-T MR imaging including 3D T1 GRE, UTE, and 3D FRACTURE sequences. CT was performed in patients with acute fractures and served as standard of reference (n = 25). Agreement of morphological features between the modalities was analyzed including the glenoid bone loss, Hill-Sachs interval, glenoid track, and the anterior straight-line length. Agreement between the modalities was assessed using Bland-Altman plots, Student's t-test, and Pearson's correlation coefficient. Inter- and intrareader assessment was evaluated with weighted Cohen's κ and intraclass correlation coefficient. RESULTS All osseous pathologies were detected accurately on all three CT-like sequences (n = 25, κ = 1.00). No significant difference in the percentage of glenoid bone loss was found between CT (mean ± standard deviation, 20.3% ± 8.0) and CT-like MR images (FRACTURE 20.6% ± 7.9, T1 GRE 20.4% ± 7.6, UTE 20.3% ± 7.7, p > 0.05). When comparing the different measurements on CT-like images, measurements performed using the UTE images correlated best with CT. CONCLUSION Assessment of bony Bankart lesions and other osseous pathologies was feasible and accurate using CT-like images based on 3-T MRI compared with conventional CT. Compared to the T1 GRE and FRACTURE sequence, the UTE measurements correlated best with CT. CLINICAL RELEVANCE STATEMENT In an acute trauma setting, CT-like images based on a T1 GRE, UTE, or FRACTURE sequence might be a useful alternative to conventional CT scan sparing associated costs as well as radiation exposure. KEY POINTS • No significant differences were found for the assessment of the glenoid bone loss when comparing measurements of CT-like MR images with measurements of conventional CT images. • Compared to the T1 GRE and FRACTURE sequence, the UTE measurements correlated best with CT whereas the FRACTURE sequence appeared to be the most robust regarding motion artifacts. • The T1 GRE sequence had the highest resolution with high bone contrast and detailed delineation of even small fractures but was more susceptible to motion artifacts.

Abstract
Background Glenohumeral instability is a challenging problem in children and adolescents. For patients with anterior glenoid bone loss, the Latarjet procedure is an effective treatment option. However, concerns about coracoid size and morphology may limit its utilization within this patient population. The purpose of this study was to establish normative data on coracoid and glenoid size and morphology among a large cohort of adolescent patients and describe the anatomic relationships with demographic factors. Methods This is a retrospective cross-sectional study of a consecutive series of 584 patients aged 12-21 years after a chest computed tomography scan for non-shoulder related trauma at a single level I trauma center. Demographic characteristics were collected from the electronic medical record, and the following coracoid anatomic measurements were obtained from computed tomography scans: coracoid length, coracoid thickness, coracoid width, glenoid height, and glenoid width. The ratio of coracoid thickness to glenoid width was calculated to estimate the percent bone loss that could be addressed with a traditional Latarjet coracoid transfer. To ensure reliability among 3 reviewers, all measured the same 25 scans and inter-rater reliability was excellent with all Kappa coefficients >0.81. The remaining scans were divided equally and assessed separately by these reviewers. Correlation coefficients were used to quantify the relationships between all anatomic measures and the age, weight, and height of individuals. Growth curves for each measurement were modeled using quantile regression with height and height∗height as predictors. Additionally, we stratified the growth curves by sex, when significant. Of the 584 subjects, 55% were male, and average age was 19 years (range 12, 21). Results All growth curves illustrated increase anatomic size across the height range of 145-190 cm. The growth curve including all patients (Fig. 1) illustrated that the 50% percentile of median coracoid length increased from approximately 28 to 32 mm. In addition to height, sex was a significant predictor for coracoid width and glenoid width. The median coracoid width increased from approximately 9.5 to 10.2 mm for females compared to an increased width from approximately 10 to 11 mm for males. The median glenoid width for females increased from approximately 21 to 25 mm and for males the median glenoid width increased from just under 22 to 25.5 mm. Conclusions Among children and adolescents, coracoid and glenoid size are correlated with patient height. These data can help guide patient selection for the Latarjet procedure.

Abstract
Background Humeral head reconstruction with fresh osteochondral allografts (OCA) serves as a potential treatment option for anatomic reconstruction. More specifically, talus OCA is a promising graft source because of its high congruency with a dense cartilaginous surface. Purpose To analyze the surface geometry of the talus OCA plug augmentation for the management of shoulder instability with varying sizes of Hill-Sachs lesions (HSLs). Study Design Controlled laboratory study. Methods Seven fresh-frozen cadaveric shoulders were tested in this study. The humeral heads were analyzed using actual patients' computed tomography scans. Surface laser scan analysis was performed on 7 testing states: (1) native state; (2) small HSL; (3) talus OCA augmentation for small HSL; (4) medium HSL; (5) talus OCA augmentation for medium HSL; (6) large HSL; and (7) talus OCA augmentation for large HSL. OCA plugs were harvested from the talus allograft and placed in the most medial and superior aspect of each HSL lesion. Surface congruency was calculated as the mean absolute error and the root mean squared error in the distance. A 1-way repeated-measures analysis of variance was performed to evaluate the effects of the difference in the HSL size and associated talus OCA plugs on surface congruency and the HSL surface area. Results The surface area analysis of the humeral head with the large (1469 ± 75 mm2), medium (1391 ± 81 mm2), and small (1230 ± 54 mm2) HSLs exhibited significantly higher surface areas than the native state (1007 ± 88 mm2; P < .001 for all sizes). The native state exhibited significantly lower surface areas as compared with after talus OCA augmentation for large HSLs (1235 ± 63 mm2; P < .001) but not for small or medium HSLs. Talus OCA augmentation yielded improved surface areas and congruency after treatment in small, medium, and large HSLs (P < .001). Conclusion Talus OCA plug augmentation restored surface area and congruency across all tested HSLs, and the surface area was best improved with the most common HSLs-small and medium. Clinical Relevance Talus OCA plugs may provide a viable option for restoring congruity of the shoulder in patients with recurrent anterior glenohumeral instability and an HSL.

Abstract
BACKGROUND Traumatic anterior shoulder instability affects athletes at a higher rate compared with the general population. In recent years, indications for arthroscopic remplissage, an adjunct procedure classically used to reduce the recurrence of anterior shoulder instability in patients with off-track Hill-Sachs lesions, have expanded. PURPOSE To investigate return-to-sport (RTS) rates, functional outcomes, and adverse events in athletes who underwent arthroscopic Bankart repair with remplissage compared with surgical alternatives such as Bankart repair alone or the Latarjet procedure. STUDY DESIGN Systematic review and meta-analysis; Level of evidence, 4. METHODS A literature review of the Embase, PubMed (MEDLINE), and Web of Science databases was conducted for articles published before May 22, 2022. For the systematic review, 16 of 457 studies that reported RTS rates at any time point after remplissage were deemed eligible for inclusion in quantitative analysis and 17 of 457 studies in qualitative analysis. For the meta-analysis, 8 of 457 studies reported RTS rates after remplissage compared with surgical alternatives including Bankart repair alone or the Latarjet procedure and were deemed eligible for inclusion. RESULTS In total, 538 athletes underwent remplissage and were included in the study. RTS at any level was achieved by 86% (395/457) of patients, and the odds of RTS at any level were significantly higher after remplissage compared with surgical alternatives (odds ratio [OR], 2.71 [95% CI, 1.14-6.43]; P = .02). The odds of RTS at a previous or higher level were also significantly higher after remplissage compared with surgical alternatives (OR, 2.07 [95% CI, 1.29-3.31]; P = .002). The mean Rowe score increased significantly from 43.9 ± 7.77 preoperatively (n = 173) to 92.2 ± 4.02 after remplissage (n = 397) (P < .001), but there was no significant difference in Rowe scores between remplissage and surgical alternatives (P = .54). After remplissage, the recurrence rate was 5.0% for athletes (n = 220) and 7.3% for all patients (n = 634), with a mean time to recurrence of 24.0 ± 12.5 months. Reoperations occurred in 3.6% of athletes (n = 110) and 4.1% of all patients (n = 445). Recurrence and reoperations were significantly less likely after remplissage compared with surgical alternatives (OR, 0.18 [95% CI, 0.08-0.39]; P < .001 and OR, 0.17 [95% CI, 0.06-0.50]; P = .001, respectively). CONCLUSION Arthroscopic Bankart repair with remplissage augmentation significantly improved RTS rates among athletes, both at any level and at previous levels of play. Additionally, remplissage appeared to significantly decrease recurrence and reoperation rates compared with surgical alternatives such as Bankart repair alone or the Latarjet procedure.

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
The arthroscopic remplissage procedure has been described to successfully treat engaging Hill-Sachs lesions and improve shoulder stability. Several variations of this technique have been described, including remplissage with 1 or 2 knotted or knotless anchors, remplissage with double or triple bridging pulleys, and remplissage with or without a subacromial view. However, most techniques use anchors in combination with round sutures. This article describes an all-arthroscopic articular knotless remplissage technique using a strong, flat, double-strand suture tape bridge fixed with 2 small anchors under direct joint visualization and reduction of the capsule and infraspinatus without requiring a subacromial view.

Abstract
Background Engaging Hill-Sachs lesions (HSLs) pose a significant risk for failure of surgical repair of recurrent anterior shoulder instability. Reconstruction with fresh osteochondral allograft (OCA) has been proposed as a treatment for large HSLs. Purpose To determine the optimal characteristics of talus OCA bone plugs in a computer-simulated HSL model. Study Design Descriptive laboratory study; Level of evidence, 6. Methods Included were 132 patients with recurrent anterior instability with visible HSLs; patients who had multidirectional instability or previous shoulder surgery were excluded. Three-dimensional computed tomography models were constructed, and a custom computer optimization algorithm was generated to maximize bone plug surface area at the most superior apex (superiorization) and minimize its position relative to the most medial margin of the HSL defect (medialization). The optimal number, diameter, medialization, and superiorization of the bone plug(s) were reported. Percentages of restored glenoid track width and conversion from off- to on-track HSLs after bone plug optimization were calculated. Results A total of 86 patients were included in the final analysis. Off-track lesions made up 19.7% of HSLs and, of these, the mean bone plug size was 9.9 ± 1.4 mm, with 2.2 mm ± 1.7 mm of medialization and 3.3 mm ± 2.9 mm of superiorization. The optimization identified 21% of HSLs requiring 1 bone plug, 65% requiring 2 plugs, and 14% requiring 3 plugs, with a mean overall coverage of 60%. The mean width of the restored HSLs was 68%, and all off-track HSLs (n = 17) were restored to on-track. A Jenks natural-breaks analysis calculated 3 ideal bone plug diameters of 8 mm (small), 10.4 mm (medium), and 12 mm (large) in order to convert this group of HSLs to on-track. Conclusion Using a custom computer algorithm, we have demonstrated the optimal talus OCA bone plug diameters for reconstructing HSLs to successfully restore the HSL track and, on average, 60% of the HSL surface area and 68% of the HSL width. Clinical Relevance Reconstructing HSLs with talus OCA is a promising treatment option with excellent fit and restoration of HSLs. This study will help guide surgeons to optimize OCA bone plugs from the humeral head, femoral head, and talus for varying sizes of HSLs.

Abstract
The shoulder, being the most mobile joint in the human body, is often susceptible to dislocations and subluxations more so than other joints. As such, shoulder instability constitutes a common complaint among patients worldwide, especially those who are young, participate in contact sports, and have increased innate flexibility in their joints. Management options in the setting of instability vary between conservative and surgical options that aim to mitigate symptoms and allow return of function. Surgical options can be arthroscopic and open, with a general shift among surgeons towards utilizing arthroscopic surgery in the past several decades. Nevertheless, open procedures still play a role in managing shoulder instability patients, especially those with significant bone loss, recurrent instability, coexisting shoulder pathologies, and high risk of failure with arthroscopic surgery. In these clinical settings, open procedures, like the Latarjet procedure, open Bankart repair, glenoid bone augmentation using iliac crest autograft or distal tibial allograft, and salvage options like glenohumeral arthrodesis and arthroplasty may show good clinical outcomes and low recurrence rates. Each of these open procedures possesses its own set of advantages and disadvantages and entails a specific set of indications based on published literature. It is important to cater treatment options to the individual patient in order to optimize outcomes and reduce the risk of complications. Future research on open shoulder stabilization procedures should focus on the long-term outcomes of recently utilized procedures, investigate different graft options for procedures involving bone augmentation, and conduct additional comparative analyses in order to establish concrete surgical management guidelines.

Abstract
PURPOSE OF REVIEW Patients with seizure disorders commonly suffer shoulder dislocations and subsequent instability. Due to high rates of recurrence and bone loss, management of this instability and associated pathology has proven to be more complex than that of patients without seizure disorders. The ultimate goal of this review is to outline the various treatment modalities and their respective outcomes in this complex patient population. RECENT FINDINGS Optimization of medical management of seizure disorders is imperative. However, despite these efforts, the incidence of post-operative seizure activity continues to be a concern. These subsequent episodes increase the risk of further instability and failure of surgical procedures. Overall, the use of soft tissue procedures has proven to result in increased recurrence of instability compared to bone-block augmenting and grafting procedures. There are a variety of bone-block procedures that have been described for anterior and posterior instability. Despite their success in decreasing further instability, they are associated with several complications that patients should be informed of. There is no consensus regarding the optimal surgical management of shoulder instability in patients with seizure activity. A multidisciplinary approach to the management of the seizure activity is paramount to the success of their treatment. Further studies are required to evaluate the optimal timing and type of surgical intervention for individualized cases.

Arthroscopic findings of the glenohumeral joint in symptomatic anterior instabilities: comparison between overhead throwing disorders and traumatic shoulder dislocation. J Shoulder Elbow Surg 2023; 32:776-785. [PMID: 36343790 DOI: 10.1016/j.jse.2022.10.005] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/16/2022] [Revised: 09/21/2022] [Accepted: 10/04/2022] [Indexed: 11/06/2022]
Abstract
BACKGROUND The term shoulder instability refers to a variety of mechanisms and clinical presentations. One of the common pathologies of throwing disorders is internal impingement with anterior instability. Most throwing athletes with symptomatic internal impingement with anterior instability exhibit positive apprehension and relocation test results, whereas those with recurrent anterior shoulder instability display positive apprehension test results. While the glenoid labrum-inferior glenohumeral ligament complex is a significant critical stabilizer for the prevention of anterior shoulder dislocation, the characteristics of the essential lesion in internal impingement with anterior instability have not been determined yet. This study aimed to compare the intra-articular lesion of athletes with internal impingement related to the overhead throwing motion in athletes with a traumatic shoulder dislocation. METHODS Sixty-one athletes (all men; mean age, 25.2 ± 12.6 yr) who underwent an arthroscopic procedure were divided into 2 groups: 25 in the throwing group and 36 in the dislocation group. All shoulders had subtle glenohumeral instability defined by a positive anterior apprehension test and a relocation test. Those with voluntary and multidirectional instability and large glenoid bone loss (more than 25%) were excluded from the current study. All shoulders were evaluated for the following evidence: rotator cuff injury, superior labrum tear anterior and posterior lesions, labral pathologies including Bankart lesions, osteochondral lesions to the humeral head, biceps tendon fraying or rupture, and inferior glenohumeral ligament and middle glenohumeral ligament (MGHL) conditions. RESULTS Arthroscopic findings of the throwing group showed more supraspinatus injuries (92% and 25%, P < .001), type II superior labrum tear anterior and posterior lesions (60% and 3%, P < .001), posterosuperior labral lesions (92% and 39%, P < .001), and hypoplastic MGHLs (56% and 6%, P < .001) and lesser Bankart lesions (8% and 92%, P < .05) than those of the dislocation group. CONCLUSIONS These results indicate that the characteristic lesions of internal impingement with anterior instability in throwing athletes include partial thickness rotator cuff tears, superior labrum tear anterior and posterior lesions, posterosuperior labral tears, and hypoplastic MGHLs. As expected, the physiopathology of internal impingement with anterior instability in throwing athletes may be related to the dysfunction of the anterosuperior glenohumeral capsular ligament, including the MGHL, rather than the inferior glenohumeral ligament as in traumatic anterior shoulder dislocations. These findings would be useful for defining treatment strategies for internal impingement with anterior instability in overhead throwing athletes.

Abstract
While still hotly debated, primary arthroscopic management of the first-time anterior shoulder dislocation has an extensive list of known benefits: lower overall health care costs, improved patient-reported outcomes, a vast reduction in secondary instability, and higher quality-of-life measures. Yet, despite these meaningful contributions to health care quality, we continue to bypass the predictable success of an acute arthroscopic Bankart repair in order to tempt fate with "a trial" of nonoperative care for our young, high-risk collision athletes. Whether for the in-season athlete, the "early responder" with limited apprehension, subluxations with spontaneous reduction, or those stoically committed to nonsurgical care, we as physicians are often complicit in this shared risk taking and ceremonial weighing of the risks and benefits for treatment options after primary shoulder instability. Even just 1 additional episode of instability recurrence can double (or triple) the rate of glenohumeral bone loss. Furthermore, subsequent anterior shoulder instability compromises subjective shoulder function, heightens risk of secondary recurrence and/or revision, and increases the likelihood of requiring more advanced surgical management, such as with a Latarjet or other anterior bone block procedure. We must maintain a sense of urgency toward surgical treatment, particularly in young, high-demand athletes with persistent instability. To parrot the wisdom of our shoulder mentors, hear my humble plea: you don't have to fix the shoulder after the first anterior dislocation, but you should definitely do it before the second!

Abstract
Shoulder instability is the separation of the humeral head from the glenoid. Injury to the static and dynamic stabilizers can result in instability. Anterior shoulder instability is the predominant form of instability. It is usually a result of trauma. Posterior shoulder instability often presents with an insidious onset of pain. Multidirectional instability of the shoulder is symptomatic laxity in more than one plane of motion. The primary goal of rehabilitation is to restore pain-free mobility, strength, and functioning. Rehabilitation implements range of motion and strengthening exercises to restore proprioceptive control and scapular kinematics.

Abstract
BACKGROUND Advances in the understanding and management of glenoid bone loss in shoulder instability have led to the development of alternative bony reconstruction techniques to the Latarjet using free bone grafts, but little is known about surgeon adoption of these procedures. This study sought to characterize surgeon variation in the use of glenoid bone reconstruction procedures for shoulder instability and ascertain reasons underlying procedure choice. METHODS A 9-question survey was created and distributed to 160 shoulder surgeons members of the PacWest Shoulder and Elbow Society, of whom 65 (41%) responded. The survey asked questions regarding fellowship training, years in practice, surgical volume, preferred methods of glenoid bone reconstruction, and reasons underlying treatment choice. RESULTS All surgeons completed a fellowship, with an equal number of sports medicine fellowship-trained (46%) and shoulder and elbow fellowship-trained (46%) physicians. The majority had been in practice for at least 6 years (6-10 years: 25%; >10 years: 59%). Most (78%) performed ≤10 glenoid bony reconstructions per year, and 66% indicated that bony procedures represented <10% of their total annual shoulder instability case volume. The open Latarjet was the preferred primary reconstruction method (69%), followed by open free bone block (FBB) (22%), arthroscopic FBB (8%), and arthroscopic Latarjet (1%). Distal tibia allograft (DTA) was the preferred graft (74%) when performing an FBB procedure, followed by iliac crest autograft (18%), and distal clavicle autograft (6%). The top 5 reasons for preferring Latarjet over FBB were the sling effect (57%), the autologous nature of the graft (37%), its robust clinical evidence (22%), low cost (17%), and availability (11%). The top 5 reasons for choosing an FBB procedure were less anatomic disruption (58%), lower complication rate (21%), restoration of articular cartilage interface (16%), graft versatility (11%), and technical ease (11%). Only 20% of surgeons indicated always performing a bony glenoid reconstruction procedure in the noncontact athlete with less than 20% glenoid bone loss. However, that percentage rose to 62% when considering a contact athlete with the same amount of bone loss. CONCLUSIONS Although open Latarjet continues to be the most popular glenoid bony primary reconstruction procedure in shoulder instability, nearly 30% of shoulder surgeons in the western United States have adopted FBB techniques as their preferred treatment modality--with DTA being the most frequently used graft. High-quality comparative clinical effectiveness research is needed to reduce decisional conflict and refine current evidence-based treatment algorithms.

[PMID: 36866290 PMCID: PMC9971905 DOI: 10.1016/j.asmr.2022.11.010] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/12/2022] [Accepted: 11/08/2022] [Indexed: 12/24/2022] Open
Abstract
Purpose To demonstrate the learning curve associated with the arthroscopic Latarjet procedure and create a timetable to proficiency. Methods Using retrospective data of a single surgeon, consecutive patients who had an arthroscopic Latarjet procedure performed between December 2015 and May 2021 were initially reviewed for inclusion in the study. Patients were excluded if medical data were insufficient for accurate surgical time record, their surgery was transitioned to open or minimally invasive, or if their surgery was performed in conjunction with a second procedure for a separate issue. All surgeries were performed on an outpatient basis and sports participation was the most common reason for initial glenohumeral dislocation. Results Fifty-five patients were identified. Of these, 51 met the inclusion criteria. Analysis of operative times for all 51 procedures demonstrated that proficiency with the arthroscopic Latarjet procedure was obtained after 25 cases. This number was determined by 2 methods using statistical analysis (P < .05). The average operative time over the course of the first 25 cases was 105.68 minutes and beyond 25 cases was 82.41 minutes. Male gender was seen in 86.3 percent of the patients. The average age of the patients was 28.6 years old. Conclusions With continued transition towards bony augmentation procedures for addressing glenoid bone deficiency there is an increasing demand for the arthroscopic bony glenoid reconstruction procedures including the Latarjet procedure. It is a challenging procedure with a substantial initial learning curve. For a skilled arthroscopist there is a significant decrease in overall surgical time after the first 25 cases. Clinical Relevance The arthroscopic Latarjet procedure has advantages over the open Latarjet approach; however, it is controversial because it is technically challenging. It is important for surgeons to understand when they can expect to be proficient with the arthroscopic approach.

[PMID: 36532154 PMCID: PMC9756371 DOI: 10.1177/23259671221142257] [Citation(s) in RCA: 10] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/29/2022] [Accepted: 09/15/2022] [Indexed: 08/03/2023] Open
Abstract
BACKGROUND Surgical management of anterior shoulder instability continues to evolve. The clinical effectiveness of arthroscopic Bankart repair with remplissage (REMP) in patients with increasing glenoid bone loss (GBL) has not been thoroughly compared with Latarjet. PURPOSE/HYPOTHESIS The purpose of this study was to compare 2-year outcomes of REMP versus open Latarjet in patients with >15% GBL. We hypothesized that there would be no difference. STUDY DESIGN Cohort study; Level of evidence, 3. METHODS A multicenter, retrospective study was performed on a consecutive series of patients who underwent primary REMP or Latarjet by 4 shoulder specialists between August 2013 and December 2019 for >15% GBL. Procedure performance was based on shared decision making between the surgeon and patient. Baseline and 2-year postoperative range of motion (ROM) and the following patient-reported outcomes (PROs) were collected: Western Ontario Shoulder Instability Index, Single Assessment Numeric Evaluation, and visual analog scale for pain. Return to sport, satisfaction, complications, recurrence, and revisions were reviewed. RESULTS A total of 47 patients were available for study, including 22 who underwent REMP and 25 who underwent Latarjet. Baseline demographic characteristics, ROM, and PROs were similar between the groups. Mean preoperative GBL (REMP 25.8% ± 7.8% vs Latarjet 25.1% ± 9.0%; P = .800) and off-track lesions (REMP 59.1% vs Latarjet 44.0%; P = .302) were similar. Postoperative change in external rotation favored Latarjet (10° ± 22° vs -4° ± 13°; P = .017). Postoperative PROs, return to the sports (86.4% vs 87.5%; P = .99), and satisfaction (95.5% vs 95.8%; P = .99) were similar between groups. There were no recurrent dislocations in either group. One infected hematoma was encountered in the Latarjet cohort. CONCLUSION At short-term follow-up, the hypothesis was upheld. REMP and Latarjet provided similar outcomes for patients with >15% GBL, although REMP patients experienced slightly decreased external rotation. Although larger series and longer-term follow-ups are required, remplissage may be considered in patients with >15% glenoid bone loss.

Abstract
PURPOSE Recurrent shoulder dislocations can result in kinematic changes of the glenohumeral joint. The number of prior shoulder dislocations may contribute to increased severity of capsulolabral lesions. The kinematics of the glenohumeral joint following multiple dislocations remain poorly understood. The purpose of this study was to assess the kinematics of the glenohumeral joint during anterior dislocations of the shoulder, and more specifically, altered translational motion following multiple dislocations. The kinematics of the glenohumeral joint were hypothesized to change and correlate with the number of dislocations. METHODS Eight fresh-frozen cadaveric shoulders were dissected free of all soft tissues except the glenohumeral capsule. Each joint was mounted in a robotic testing system. At 60 degrees of glenohumeral abduction, an internal and external rotational torque (1.1 Nm) were applied to the humerus, and the resulting joint kinematics were recorded. Anterior forces were applied to the humerus to anteriorly dislocate the shoulder and the resulting kinematics were recorded during each dislocation. Following each dislocation, the same rotational torque was applied to the humerus, and the resulting joint kinematics were also recorded. A repeated-measures analysis of variance (ANOVA) was used to compare the kinematics following each dislocation. RESULTS During the 7th, 8th, 9th, and 10th dislocations, the humerus significantly translated superiorly compared with the shoulder during the 1st dislocation (p < 0.05). Following the 3rd, 4th, 5th, and 10th dislocations, the humeral head significantly translated superiorly compared with the shoulder following the 1st dislocation in the position of 60 degrees of abduction in response to external rotation torque (p < 0.05). CONCLUSION Multiple anterior shoulder dislocations lead to abnormal translational kinematics and result in increased superior translation of the humerus. This may contribute to pathologic superior extension of capsulolabral injuries. Superior translation of the humerus with overhead motion in the setting of recurrent instability may also place the shoulder at risk for extension of the capsulolabral injuries.

Abstract
PURPOSE The purpose of this study was to compare functional outcome, return to sport, satisfaction, postoperative recurrence, and complications in patients undergoing primary arthroscopic Bankart repair with remplissage (ABR) to primary Latarjet. METHODS A multicenter retrospective study was performed on patients undergoing primary ABR or open Latarjet between 2013 and 2019 who had a minimum 2-year follow-up. Baseline and two-year range of motion (ROM), patient-reported outcomes (PROs: Western Ontario Shoulder Instability Index [WOSI], Single Assessment Numeric Evaluation [SANE], and visual analog scale [VAS] for pain) recurrence, return to sport, satisfaction, and complications were reviewed. RESULTS This study included 258 patients, including 70 ABRs and 188 Latarjet procedures. Baseline demographics, ROM, and PROs were similar. Mean preop glenoid bone loss (GBL) (12.3% ± 10.9% vs 7.6% ± 9%; P < .001) and off-track lesions (23% vs 13%; P = .046) were higher in the ABR group, while preoperative GBL range was similar (0-42% vs 0-47%). Changes in the VAS (1.9 vs 0.9; P = .019) and WOSI (1096 vs 805; P < .001) were improved in ABR. The percentage of patients who achieved a minimal clinically important difference was improved in WOSI for ABR and PASS for ABR in SANE, VAS, and WOSI scores. The ABR cohort reported worse changes in external rotation (ER) (-4° vs +19°; P < .001). Return to sport among overhead and contact athletes favored ABR (91.5% vs 72.7%; P = .007). Satisfaction and recurrent dislocation were similar. Surgical complications were observed in 0% of ABR cases, compared to 5.9% in the Latarjet group. CONCLUSION Primary ABR resulted in 2-year functional outcomes that were as good or superior to primary Latarjet, with higher return to sport for overhead and contact activities, fewer complications, and comparably low recurrence rates, even despite greater bipolar bone loss in the ABR cohort. However, this comes at the expense of decreased external rotation, which may be considered in individual patients. LEVEL OF EVIDENCE III, retrospective comparative study.

Abstract
Anterior glenohumeral instability has an incidence of 21.9 individuals per 100,000 in the general population. When recurrent instability occurs, bone loss to the anteroinferior glenoid can occur. The concept of "on-track" and "off-track" Hill-Sachs lesions is significant in cases of bipolar bone loss, because if humeral-sided bony injury also requires treatment, a remplissage combined with arthroscopic Bankart repair (ABR) may be an alternative to a Latarjet procedure. The Latarjet often is touted as a "definitive," because it adds bone to increase the glenoid surface area that the humeral head must travel to dislocate, and adds the dynamic "sling effect" of the conjoint tendon to further tension the lower part of the subscapularis in abduction and reduce anterior-directed forces. However, compared with ABR plus remplissage, Latarjet shows a greater risk of complications: as high as a 7.37 times relative risk. As an evidence-based surgeon who believes in the power of soft-tissue repair plus ABR, I prefer to avoid the increased complication risks of a primary Latarjet when possible. Also, my patients describe the postoperative shoulder as feeling more like the contralateral, unaffected shoulder after ABR than Latarjet.

Abstract
Background Anterior shoulder instability (ASI) is a frequently encountered pathology. Patients with a history of ASI have an increased rate of developing glenohumeral osteoarthritis and becoming candidates for shoulder arthroplasty. This systematic review aims to synthesize outcomes for patients undergoing shoulder arthroplasty with a history of ASI. Methods A comprehensive literature review was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) using PubMed, Embase, OVID Medline, Scopus, CINAHL, Web of Science, and Cochrane databases for studies evaluating the impact of prior ASI on total shoulder arthroplasty (TSA), reverse TSA, and/or hemiarthroplasty outcomes, with a minimum follow-up of 12 months. Studies were graded by level of evidence and data concerning patient demographics and outcomes were extracted. Results Sixteen articles met the inclusion criteria, including 596 patients (413 male, 181 female). The average age of the control and prior ASI groups were 57.5 and 57.0 years, respectively. Overall, 251 patients were treated operatively, 132 nonoperatively, and 213 were controls without a history of prior ASI. Shoulder arthroplasty techniques included TSA (436 shoulders), reverse TSA (130 shoulders), and hemiarthroplasty (14 shoulders). Prior anterior stabilization management included soft tissue repair, bony augmentation, and nonoperative treatment. Almost all studies reported no significant difference in subjective and functional arthroplasty outcomes between control and prior ASI groups, or between patients with prior ASI treated nonoperatively vs. surgically. Conclusion Shoulder arthroplasty in the setting of prior ASI results in improved subjective and functional outcome scores that are comparable to patients without a history of instability.

Abstract
Purpose Treatment for patients with anterior glenohumeral instability with subcritical bone loss is evolving. The purpose of this study was to compare 2-year outcomes of arthroscopic Bankart repair with and without Hill–Sachs remplissage in patients with <15% glenoid bone loss. Methods A multicenter retrospective study was performed on a consecutive series of patients who underwent primary isolated arthroscopic Bankart repair (IBR) or arthroscopic Bankart repair with remplissage (REMP) by 4 shoulder specialists between 2013 and 2019. Range of motion (ROM) and patient-reported outcomes (PROs) were collected at baseline and 2 years postoperative: Western Ontario Shoulder Instability Index, Single Assessment Numeric Evaluation, and visual analog scale for pain. Recurrence, return to sport, satisfaction, complications, and revisions also were reviewed. Results A total of 123 patients were available, including 75 IBR and 48 REMP. Baseline demographics, activity, ROM, and PROs were similar. Mean glenoid bone loss (2.5% vs 6.1%: P < .001) was greater in REMP, although the number of on-track lesions was similar (98.7% vs 93.8%: P = .298). WOSI scores were improved for REMP (196.5 vs 42.7: P = .004), but otherwise no difference in postoperative PROs or ROM. Differences between cohorts did not reach significance in return to sport (73% vs 83%: P = .203), recurrence (9.3% vs 2.1%: P = .148), or revisions (6.8% vs 2.1%: P = .403). For on-track lesions there were 6 recurrences in IBR (6 of 74; 8.1%) and 1 recurrence in REMP (1 of 45; 2.2%). Conclusions Despite slightly worse pathology, patients with subcritical bone loss who undergo REMP experience similar short-term postoperative function to isolated IBR. Recurrence, revision, and return to sport favored REMP but this study was underpowered to show statistical significance. Recurrence was common following IBR, despite subcritical glenoid bone loss and primarily on-track lesions, suggesting that REMP can be considered in on-track lesions.

Glenoid bony morphology along long diameter is associated with the occurrence of recurrent anterior shoulder dislocation: a case-control study based on three-dimensional CT measurements. INTERNATIONAL ORTHOPAEDICS 2022; 46:1811-1819. [PMID: 35668240 DOI: 10.1007/s00264-022-05463-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/08/2022] [Accepted: 05/26/2022] [Indexed: 10/18/2022]
Abstract
PURPOSE The purpose of our study is to compare the anatomic parameters of proximal humerus, glenoid, and glenohumeral joint between patients with recurrent anterior shoulder dislocation (RASD) and patients without RASD with the assistance of three-dimensional (3D) CT scans. METHODS Sixty patients were included in the study and divided into group RASD and group control. 3D-CT models of shoulder joint for each included patient were reconstructed and multiple anatomic parameters were measured. RESULTS There were no statistically significant differences between the two groups in morphological parameters of humerus and glenohumeral joints. Long diameter of glenoid was 3.50 ± 0.34 cm for patients in group RASD and 3.31 ± 0.32 cm in group control (p = 0.039). There was a statistically significant difference in the ratio of long to short diameter of glenoid (p < 0.001). Ratio of humeral head height to glenoid long diameter (Hhh/Gld) was 1.02 ± 0.07 in group RASD, significantly lower than 1.09 ± 0.08 in group control (p = 0.001). Longitudinal depth of glenoid was significantly higher in group RASD (p = 0.013). CONCLUSION The glenoid morphology along long diameter is closely correlated with the stability of glenohumeral joint, including glenoid long diameter and glenoid longitudinal depth. It is especially noteworthy that the value of Hhh/Gld decreases in patients with RASD. The difference of Hhh/Gld between the two groups reminds us that the correlation of bony structure along long diameter between glenoid and humeral head plays an important role in RASD.

Abstract
PURPOSE The purpose of this study was to establish consensus statements via a modified Delphi process on the diagnosis, nonoperative management, and Bankart repair for anterior shoulder instability. METHODS A consensus process on the treatment using a modified Delphi technique was conducted, with 65 shoulder surgeons from 14 countries across 5 continents participating. Experts were assigned to one of 9 working groups defined by specific subtopics of interest within anterior shoulder instability. RESULTS The independent factors identified in the 2 statements that reached unanimous agreement in diagnosis and nonoperative management were age, gender, mechanism of injury, number of instability events, whether reduction was required, occupation, sport/position/level played, collision sport, glenoid or humeral bone-loss, and hyperlaxity. Of the 3 total statements reaching unanimous agreement in Bankart repair, additional factors included overhead sport participation, prior shoulder surgery, patient expectations, and ability to comply with postoperative rehabilitation. Additionally, there was unanimous agreement that complications are rare following Bankart repair and that recurrence rates can be diminished by a well-defined rehabilitation protocol, inferior anchor placement (5-8 mm apart), multiple small-anchor fixation points, treatment of concomitant pathologies, careful capsulolabral debridement/reattachment, and appropriate indications/assessment of risk factors. CONCLUSION Overall, 77% of statements reached unanimous or strong consensus. The statements that reached unanimous consensus were the aspects of patient history that should be evaluated in those with acute instability, the prognostic factors for nonoperative management, and Bankart repair. Furthermore, there was unanimous consensus on the steps to minimize complications for Bankart repair, and the placement of anchors 5-8 mm apart. Finally, there was no consensus on the optimal position for shoulder immobilization. LEVEL OF EVIDENCE Level V, expert opinion.

Abstract
Shoulder instability is a relatively common injury especially in the young athletic population and its surgical management continues to remain a controversial topic in sports medicine orthopedics. Anterior instability is the most common type encountered and is estimated to have an incidence rate of 0.08 per 1000 person-years in the general population; however, this figure is likely higher in the young athletic population. While in recent practice, arthroscopic surgery has become the new gold standard for management, reported failure rates as high as 26% and high recurrence rates in specific subpopulations such as young men in high collision sports have led to the consideration of alternative open procedures such as open Bankart repair, Latarjet, capsular shift, and glenoid bone grafting. These procedures may be preferred in specific patient subgroups such as young athletes involved in contact sports and those with Hill-Sachs defects and multidirectional instability, with postoperative recurrence rates of instability as low as 10%. The purpose of this review is to provide an overview of different open surgical techniques in the management of shoulder instability and summarize patient outcomes including recurrence rates for shoulder instability, return to sport, range of motion (ROM), muscle strength, and complications either individually by procedure or in comparison with other techniques, with special focus on their impact in the athletic population.

Abstract
Background: Personal and professional biases can affect decision-making regarding
important issues in pediatric sports medicine. Gaining insight into the
opinions of health care professionals who specialize in pediatric sports
medicine will provide information that may be useful for directing ongoing
research in this field. Hypothesis: It was hypothesized that surgeons would demonstrate bias toward early
surgical intervention versus nonsurgeons. In addition, it was hypothesized
that youth sports medicine professionals who were parents of a child with a
previous major sports injury or concussion would be less likely to allow
their child to play American tackle football or return to football after a
concussion. Study Design: Cross-sectional study. Methods: An online survey was provided to the active members of the Pediatric Research
in Sports Medicine Society. We used both professional background information
and responses to questions related to personal experiences with youth sports
injuries to determine potential factors associated with underlying biases.
Survey responses among subgroups were compared using the Fisher exact test.
The Pearson correlation coefficient was used to evaluate years in practice
versus opioid use. Results: Of the survey participants, 62.5% were pediatric surgeons, and 37.5%
represented different nonsurgical youth sports medicine professions.
Surgeons were less likely than nonsurgeons to agree to allow their child to
return to football after sustaining a concussion and completing a concussion
protocol (48% vs 76%, P = .013). Surgeons were more likely
than nonsurgeons to agree to both elective shoulder stabilization after a
first-time dislocation and elective drilling of a stable knee
osteochondritis dissecans (OCD) before nonoperative treatment (41% vs 10%,
P = .003 and 52% vs 23%, P = .013,
respectively). Those who reported having a child with a concussion history
were more likely to support him or her returning to football after a
concussion (65% vs 33%, P = .026). Conclusion: Surgeons were more likely to favor elective shoulder-stabilization surgery
after a first-time dislocation and drilling of a stable knee OCD instead of
nonoperative management. Personal experience of having a child who sustained
a major sports injury or concussion did not demonstrate a bias against
participation in football or return to football after a concussion.

Ernat JJ, Lee S. Editorial Commentary: Identifying the Large Glenoid Labrum Tear Is Not as Easy as it May Seem. Arthroscopy 2021; 37:1745-1747.

Abstract
Labrum tears involving >270° of the glenoid have been termed "circumferential tears," "panlabral tears," "triple lesions," and "large tears." They are rare injuries that encompass anywhere from 2.4% to 6.5% of traumatic labral injuries. Given their rare nature, the literature has been limited to level IV studies with small patient numbers. Identifying these injuries in the clinical setting can be challenging, as patients can present with signs and symptoms of unidirectional instability, combined instability, or even microinstability. However, we know that magnetic resonance arthrography seems to be more helpful than magnetic resonance imaging, and that these patients will most often present with pain in between multiple instability episodes. Given that the gold standard treatment for these injuries is operative intervention, recognizing them as opposed to an isolated unidirectional injury is critical for surgical planning and patient counseling purposes. Isolating other demographic and historical risk factors in addition to physical examination and imaging may be key in making the diagnosis.

Recurrent Instability after Arthroscopic Glenoid Labral Repair with a Minimum of Three Points of Fixation: Do the Number of Anchors or Fixation Points Correlate to Outcomes? Surg Technol Int 2021; 38:433-439. [PMID: 33724436 DOI: 10.52198/21.sti.38.os1411] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 06/12/2023]
Abstract
INTRODUCTION The goal of this study was to evaluate the recurrence rate of instability following arthroscopic Bankart repairs in regard to the number and types of fixation utilized. A Bankart lesion is a tear in the anteroinferior capsulolabral complex within the shoulder, occurring in association with an anterior shoulder dislocation. These injuries can result in glenoid bone loss, decreased range of motion, and recurrent shoulder instability. Successful repair of these lesions has been reported in the literature with repair constructs that have three points of fixation. However, the definition of "one point of fixation" is yet to be fully elucidated. MATERIALS AND METHODS A consecutive series of arthroscopically repaired Bankart lesions were evaluated pertaining to the points of fixation required to achieve shoulder stability. This included the number, position, and types of anchors used. Patients consented to complete a series of surveys at a minimum of two years postoperatively. The primary outcome was to determine recurrent instability via the UCLA Shoulder Score, the ROWE Shoulder Instability Score, and the Oxford Shoulder Score. A secondary outcome included pain on a Visual Analog Scale (VAS). RESULTS There were 116 patients reviewed, 46 patients achieved three points of fixation in their surgical repair via two anchors and 70 patients achieved a similar fixation with three or more anchors. There was no significant difference in the mean age, gender, or body mass index (BMI). Patients receiving two anchors demonstrated recurrent instability 8.7% of the time (4 of 46 patients). Patients who received three or more anchors demonstrated recurrent instability 8.6% of the time (6 of 70 patients). Overall, there was no statistical significance between the number/types of anchors used. Between the two cohorts, there was no statistically significant difference found between VAS, ROWE, UCLA, and Oxford Scores. There was a significant difference in pain reported on the VAS scale with an average VAS score of 0.43 versus 2.5 in those without and with recurrent instability respectively. CONCLUSION Contention still exists surrounding the exact definition of "a point of fixation" in arthroscopic Bankart repairs. Three-point constructs can be created through a variety of combinations including anchors and sutures, ultimately achieving the goal of a stable shoulder.
