High long-term failure rates after arthroscopic Bankart repair in younger patients with recurrent shoulder dislocations: A plea for early treatment. Knee Surg Sports Traumatol Arthrosc 2024. [PMID: 39101229 DOI: 10.1002/ksa.12391] [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: 01/28/2024] [Revised: 07/07/2024] [Accepted: 07/15/2024] [Indexed: 08/06/2024]
Abstract
PURPOSE To determine arthroscopic Bankart repair outcomes and recurrence risk factors at a minimum 5-year follow-up. METHODS Retrospective assessment of prospectively collected data, single-cohort study of patients who underwent arthroscopic Bankart repair with a minimum 5-year follow-up. Demographical and preoperative instability features were collected. Primary outcome was recurrent instability set as dislocation or subluxation. Secondary outcomes were revision surgery, postoperative instability degree according to Manta criteria, objective and subjective clinical and functional status, assessed by the Rowe, Western Ontario Shoulder Index (WOSI) and Subjective Shoulder Value (SSV) scores. Return to sport and postoperative sports activity at the final follow-up were also recorded. RESULTS One-hundred and seventy-two patients, 82% men, average age at surgery 29.5 ± 9.2 years, were included. At a mean follow-up of 8.3 ± 2.6 years, recurrent instability occurred in 53 of 172 patients (30.8%). Revision surgery was required in 23/53 (43.4%) of shoulder with recurrent instability. Recurrence occurred within the first 2 years postoperative in 49% of the shoulders, whereas 51% of recurrences occurred after this period. Recurrence took place after a traumatic event in 25% and 56%, respectively. Recurrence rates were higher in patients who underwent surgery after two or more dislocations (p = 0.029). Patients younger at the time of first dislocation, younger at surgery and those with a higher preoperative degree of instability also showed significantly higher rates of recurrence (p = 0.04, p = 0.02, p = 0.03). Postoperative ROWE, WOSI and SSV scores were significantly worse in patients with recurrent instability (p < 0.001). Return-to-sports rate was also lower in patients with postoperative recurrence (p < 0.001). CONCLUSION The arthroscopic Bankart repair was associated with a high long-term recurrence rate, and its effectiveness decreased over time. The lowest recurrence rates in arthroscopic Bankart repair were achieved in older patients with only one prior instability episode and a lower instability degree. LEVEL OF EVIDENCE Level IV.

Abstract
PURPOSE OF REVIEW Arthroscopic remplissage has continued to gain popularity as an adjunct to Bankart repair for patients with anterior shoulder instability. Although the original remplissage technique was described over 15 years ago, our understanding of when and how to use this procedure continues to evolve. This article provides a review of how remplissage affects shoulder biomechanics, compares clinical outcomes between remplissage and other procedures for shoulder instability, and discusses current indications for remplissage. RECENT FINDINGS Current research focuses on the use of remplissage across a wide range of glenoid bone loss. Remplissage appears effective at preventing recurrent instability in patients with glenoid bone loss up to 15% of the glenoid width. However, once glenoid bone exceeds 15%, outcomes tend to favor bony reconstruction procedures such as Latarjet. Results of biomechanical studies examining shoulder range of motion (ROM) after remplissage are mixed, though clinical studies tend to report no significant limitations in ROM when remplissage is added to a Bankart repair. Adding a remplissage to conventional Bankart repair may improve clinical outcomes and lower rates of recurrent instability without significantly altering shoulder ROM. However, surgeons should recognize its limitations in treating patients with large amounts of glenoid bone loss and should be prepared to discuss alternative procedures on a case-by-case basis. Absolute indications and contraindications for remplissage are not well defined currently and require further scientific research.

Abstract
BACKGROUND Several arthroscopic glenoid bone augmentation techniques have been introduced to treat patients affected by anterior shoulder instability associated with critical bone loss. The efficacy of the different arthroscopic bony procedures has not been compared yet. PURPOSE To compare the recurrence, complication, and reoperation rates of the arthroscopic Latarjet (AL) and arthroscopic free bone block (ABB) procedures for anterior shoulder instability. STUDY DESIGN Meta-analysis and systematic review; Level of evidence, 4. METHODS A systematic search was conducted in MEDLINE/PubMed, Web of Science, and Embase to identify clinical studies reporting the outcomes of the AL and ABB procedures. The following search phrases were used: "Arthroscopic" AND "Bone Block" OR "Bone Graft," and "Arthroscopic" AND "Glenoid Augmentation" OR "Glenoid Reconstruction," and "Arthroscopic" AND "Latarjet" OR "Coracoid Graft" OR "Coracoid Transfer." Exclusion criteria were <24 months of minimum follow-up, sample size <10 cases, revision after previous glenoid bone grafting, epilepsy, and multidirectional instability. Data regarding the study design, patient characteristics, surgical technique, and outcomes were extracted and analyzed. A proportional meta-analysis was conducted to compare the complication, recurrence, and reoperation rates between the 2 groups. Multiple subgroup analyses were performed to analyze the incidence of each complication and assess the weight of different fixation methods (in the whole cohort) or different graft types (in the ABB group). The modified Coleman Methodology Score was used to assess the risk of bias. RESULTS Of 5010 potentially relevant studies, 18 studies regarding the AL procedure (908 cases) and 15 studies regarding the ABB procedure (469 cases) were included. The 2 groups were comparable in age (P = .07), sex (P = .14), glenoid bone loss (P = .14), number of preoperative dislocations (P = .62), proportion of primary and revision procedures (P = .95), length of follow-up (P = .81), modified Coleman Methodology Score (P = .21), and level of evidence (P = .49). There was no difference in the recurrence (P = .88), reoperation (P = .79), and complication (P = .08) rates. The subgroup analyses showed a higher rate of hardware-related complications for screw fixation compared with flexible fixation (P = .01). CONCLUSION The AL and ABB procedures had similar recurrence, reoperation, and complication rates. Screw fixation of the bone graft was related to an increased risk of complications compared with flexible fixation. REGISTRATION CRD42022368153 (PROSPERO).

Abstract
BACKGROUND To analyze the causes of failure after a Latarjet procedure and to evaluate the results of revision surgery. METHODS Single-cohort, retrospective, observational study. Fifteen patients (13 males, mean age at revision failed Latarjet 38.9 years [range, 20-57]) with anterior glenohumeral instability who underwent a revision surgery for a failed Latarjet procedure were reviewed. Failure was defined as subluxation or dislocation. Demographic features, the reason for failure, type of lesions observed, and postoperative clinical and functional status were recorded. Functional status was assessed with the Rowe score. Subjective clinical evaluation was performed using the Western Ontario Shoulder Instability Index (WOSI) and Subjective Shoulder Value (SSV). RESULTS Recurrence occurred in the first year following the Latarjet procedure in 11 patients (73.3%). The causes of failure were graft avulsion in 3 cases, fracture in 1, coracoid misposition in 2 cases, graft nonunion in 1, advanced osteolysis in 4 cases, and persistence of an off-track Hill-Sachs lesion in 1. In 3 cases, no identifiable cause of failure but generalized severe hyperlaxity was found. Regarding revision surgery after the Latarjet procedure, 8 patients underwent an arthroscopic Eden-Hybinette procedure and in 3 patients the graft was repositioned. In the remaining 4 patients, an extra-articular capsular reinforcement was performed. Regarding the latter, 1 patient suffered new dislocations and required an additional revision surgery consisting of an Eden-Hybinette procedure. All patients remained stable after the revision surgery at the latest follow-up, except 2 who reported subluxations after an arthroscopic Eden-Hybinette and an extra-articular capsular reinforcement, but no additional surgical procedure was required. Functional status after revision surgery was satisfactory, with a mean Rowe score of 78 (10-100), WOSI score of 829 (225-1425), and an SSV score of 67 points (40-90). CONCLUSION The causes of failure after a Latarjet procedure were poor bone graft due to mispositioning, avulsion, fracture or resorption, generalized hyperlaxity, and incomplete restoration of the glenoid track. Our study demonstrates that when the cause of failure is identified and addressed, stability is restored, and clinical and functional scores improved.

Abstract
The risk of Hill-Sachs lesion (HSL) to cause instability depends not only on the HSL but also on the glenoid size. Clinically, the only method to assess the risk of instability considering the dynamic interaction of both, the HSL together with the glenoid bone loss, is the glenoid track concept. Since it was introduced in a cadaveric study, its clinical efficacy and validity have been reported in the literature. Sometimes, the medial margin of the footprint (lateral margin of the glenoid track) is difficult to identify when a HSL is overriding the footprint. In such cases, we propose a method to draw an imaginary line connecting 2 landmarks. Although 3-dimensional computed tomography is the most accurate and widely used method to assess on/off-track lesions, our interest gradually is shifting toward magnetic resonance imaging (MRI), which has no radiation concern. The current magnetic resonance method is still under way. There are various risk factors influencing the recurrent instability after surgery. The glenoid track concept deals with only 1 of these factors, that is, instability caused by bony lesions. Therefore, the following 2 issues are important: 1) how to assess the glenoid track precisely and 2) how to incorporate other risk factors into consideration. The former can be achieved by obtaining the custom-made glenoid track width using not the fixed value of 83%, but more individualized value obtained by measuring the active horizontal extension angle of the opposite shoulder in the sitting position. At the same time, the gray zone (peripheral-track lesion) needs to be clearly defined. The latter can be achieved by incorporating the risk factors other than the bony lesions. One example is the Glenoid Track Instability Management Score (GTIMS), a combination of the glenoid track concept and the instability severity index score. This new scoring system is expected to increase the predictive potential of the scoring system, and accordingly to enhance clinical decision-making.

Abstract
INTRODUCTION Our aim was to describe whether Latarjet's technique affects subscapularis muscle innervation. MATERIALS AND METHODS We studied 12 embalmed shoulders. Subscapularis muscle innervation pattern was registered. Dimensions of the subscapularis at the glenohumeral joint line and the nerves entry point were measured. Horizontal distances from the nerves to the glenohumeral joint line as well as vertical ones to the split were measured before and after Latarjet procedure. A safe zone for the split was designed to avoid damage to subscapularis innervation. RESULTS Subscapularis muscle is innervated by three principal branches: upper, middle, and inferior subscapularis nerves. No statistical differences were found between innervation distances before and after Latarjet procedure. To perform subscapularis split along the muscle safe zone, two thirds' proportions throughout all the split must be maintained. CONCLUSIONS Subscapularis muscle has a triple innervation and was not altered after Latarjet procedure. Therefore, Latarjet technique seems to respect subscapularis muscle innervation if its split is placed through the subscapularis muscle safe zone.

Abstract
BACKGROUND The role of arthroscopic Latarjet as a revision surgery after failed arthroscopic Bankart repair has yet to be established. PURPOSE To compare clinical outcomes, recurrences, and complication rates of arthroscopic Latarjet as a revision procedure after failed arthroscopic Bankart repair versus arthroscopic Latarjet as a primary procedure. DESIGN Cohort study; Level of evidence, 3. METHODS This is a retrospective study of prospectively collected data of patients who were diagnosed with anterior shoulder instability and underwent arthroscopic Latarjet stabilization between 2009 and 2018. Patients were separated into 2 groups depending on whether Latarjet was performed after a previous instability surgery (revision) or as a primary surgery (primary). Rowe score, Western Ontario Shoulder Instability Index (WOSI), Constant-Murley Shoulder Outcome (CMSO) score, and Single Assessment Numeric Evaluation (SANE) were assessed pre- and postoperatively with a minimum 24 months of follow-up. In addition, pre- and postoperative levels of sports activity, dislocations, subluxations, and complications were assessed. RESULTS A total of 97 patients (n = 62 revision; n = 35 primary), with a mean age of 31.0 ± 8.8 and 29.4 ± 7.6 years old in the revision and primary Latajet group, respectively, met the inclusion criteria. The mean follow-up in the revision group was 32 months (24-53) and 35.5 months (27.7-42.2) in the primary Latarjet group. No significant differences between groups were observed in Rowe score (revision = 91.4, primary = 94.1; P = .223), CMSO score (revision = 90.7, primary = 94; P = .105), and SANE (revision = 85.8, primary = 87.3; P = .683) postoperatively. However, the postoperative difference in the WOSI score between the revision and primary Latarjet groups was nearly significant (510 ± 334 vs 403 ± 343, respectively; P = .05). Four (6.4%) postoperative dislocations were reported in the revision and 1 (2.8%) in the primary Latarjet group (P = .14). Patients in the revision group had a lower return to the previous level of sports participation (P = .008) and decreased external rotation with the arm by the side compared with the primary Latarjet group (P = .000). CONCLUSION Arthroscopic Latarjet as a revision surgery is a reasonable surgical option in failed Bankart repair cases. The decision to perform arthroscopic Latarjet stabilization as a revision surgery should not be influenced by the potential risk of future complications as it provides comparable clinical outcomes to the primary Latarjet procedure with a low postoperative recurrence rate. However, a decreased level of postoperative sports participation and external rotation with the arm by the side can be expected.

Arthroscopic Latarjet yields better union and prevention of instability compared to arthroscopic bony Bankart repair in shoulders with recurrent anterior instability: a systematic review. Knee Surg Sports Traumatol Arthrosc 2023; 31:5994-6005.

Abstract
PURPOSE To determine whether arthroscopic Latarjet procedure or arthroscopic bony Bankart repair provide better outcomes in terms of rates of recurrent instability, non-union and complications, as well as clinical scores and range of motion. METHODS An electronic literature search was performed using PubMed, Embase®, and Cochrane databases, applying the following keywords: "Arthroscopic bony Bankart" OR "Arthroscopic osseous Bankart" AND "Arthroscopic Latarjet" OR "Arthroscopic coracoid bone block". RESULTS The systematic search returned 1465 records, of which 29 were included (arthroscopic bony Bankart repair, n = 16; arthroscopic Latarjet, n = 13). 37 datasets were included for data extraction, on 1483 shoulders. Compared to arthroscopic Latarjet, arthroscopic bony Bankart repair had significantly higher instability rates (0.14; CI 0.10-0.18; vs 0.04; CI 0.02-0.06), significantly lower union rates (0.63; CI 0.28-0.91 vs 0.98; CI 0.93-1.00), and significantly lower pain on VAS (0.42; CI 0.17-0.67 vs 1.17; CI 0.96-1.38). There were no significant differences in preoperative glenoid bone loss, follow-up, complication rate, ROWE score, ASES score, external rotation, and anterior forward elevation between arthroscopic Latarjet and arthroscopic bony Bankart repair. CONCLUSION Compared to arthroscopic Latarjet, arthroscopic bony Bankart repair results in significantly (i) higher rates of recurrent instability (14% vs 4%), (ii) lower union rates (63% vs 98%), but (iii) slightly lower pain on VAS (0.45 vs 1.17). There were no differences in complication rates, clinical scores, or postoperative ranges of motion. LEVEL OF EVIDENCE IV.

Abstract
Background The glenoid track concept is now widely accepted, and its evaluation is considered essential for making decisions about surgery. Purpose To define preoperative descriptive data and clinical and functional features in patients with anterior glenohumeral instability according to glenoid track status and to analyze the influence of off-track Hill-Sachs (HS) lesions on preoperative shoulder function. Study Design Case-control study; Level of evidence, 3. Methods Preoperative magnetic resonance imaging or computed tomography scans were used to measure the glenoid track. Descriptive data and preoperative objective and subjective clinical and functional features were compared between patients with on-track HS lesions versus off-track HS lesions. Multivariate regression analysis was conducted to identify potential risk factors for off-track HS lesion development. Results A total of 235 patients (201 men, 34 women; mean age, 29.6 ± 8.6 years) were included- 134 shoulders (57%) with on-track HS lesions and 101 shoulders (43%) with off-track HS lesions. Age <20 years at first dislocation, number of dislocations, and ≥2 years between first dislocation and surgery were significantly different between the study groups (P = .005, P = .0001, and P = .01, respectively). Regarding these characteristics, the odds ratios for the risk of developing an off-track lesion were 2.67 (95% CI, 1.2-5.99)-1.2 times higher for each additional instability episode (95% CI, 1.025-1.14) and 2.42 times higher (95% CI, 1.176-4.608) for patients whose first dislocation was ≥2 years before surgery, respectively. Patients with off-track HS lesions had a significantly greater degree of instability (P = .04), worse Rowe scores (48.8 ± 15.3 vs 54.8 ± 28.3 for on-track HS lesions; P = .04), and lower Western Ontario Shoulder Instability scores (975 ± 454 vs 1179 ± 428 for on-track HS lesions; P = .01). Conclusion Characteristics related to a history of instability (age <20 years at first instability episode, larger number of dislocations, ≥2 years between first dislocation and surgery) were found to be risk factors for the development of an off-track HS lesion in this study. Off-track lesions led to a higher degree of instability and worse objective and subjective preoperative shoulder function versus on-track HS lesions.

Abstract
Background Up to 20% of shoulders with anterior instability are associated with superior labrum anterior-posterior (SLAP) lesions, and they remain untreated after an open Latarjet procedure. SLAP lesions can be responsible for pain and feelings of instability in high-demand patients. Purpose/Hypothesis The aim of this study was to compare the early functional outcomes and return to sport rates in athletes after the Latarjet procedure with versus without associated SLAP lesions. It was hypothesized that untreated SLAP lesions would not influence clinical results. Study Design Cohort study; Level of evidence, 3. Methods Inclusion criteria were athletes with anterior shoulder instability treated with Latarjet procedure, a minimum follow-up of 1 year, and an available preoperative computed tomography arthrogram. We recorded patient characteristics; type of sport; bone loss; Rowe, Single Assessment Numeric Evaluation (SANE), and 11-item Disabilities of the Arm, Shoulder and Hand (QuickDASH) scores; 5-point pain and satisfaction scores; reported apprehension; and return to sport. Patients with and without a preoperative type 5 SLAP lesion on imaging were compared. Results Fifty patients were included (mean age, 22 ± 5 years [range, 16-36 years]; mean follow-up, 27 ± 9 months [range, 12-42 months]). Thirty-four patients practiced contact sports, including 20 rugby players. Twelve patients (24%) had a preoperative SLAP lesion. Groups with (+) and without (-) a SLAP lesion were comparable in terms of age, sex, number of instability episodes, type of sport, and glenoid and humeral bone loss. The SLAP+ group had significantly worse outcomes with a lower Rowe score (79 ± 23 vs 91 ± 15; P = .018) and painless rate (50% vs 77%; P = .04). There were no significant differences between the groups in SANE score (SLAP+ vs SLAP-: 80% vs 87%), QuickDASH score (8% vs 8%), return to sport (83% vs 91%), apprehension (79% vs 50%), and reported satisfaction. There was 1 episode of postoperative subluxation in each group. Conclusion Patients who underwent an open Latarjet procedure with an associated SLAP tear more frequently reported postoperative pain than those without a SLAP lesion. Patients with untreated SLAP tears had significantly lower Rowe scores, although SANE score and return to sport were not significantly different between the groups.

Abstract
Bone loss has been identified as a risk factor for recurrent shoulder dislocations or failure after soft tissue repair. Although the range for "critical" bone loss is yet to be determined, glenoid and humeral bone defects should not be regarded as independent problems, but the interaction between them during shoulder motion should be evaluated as suggested by the glenoid track concept. The glenoid track concept is now widely accepted and considered essential for making decisions about surgery. Soft-tissue procedures usually work well in patients with on-track Hill-Sachs lesions but in off-track lesions do not. In this situation additional procedures should be performed.Different surgical options have been described to address off-track Hill-Sachs lesions, most commonly remplissage, Latarjet or free bone block procedures. Coracoid graft and free bone grafts convert the off-track Hill-Sachs lesion into on-track by lengthening the glenoid-track, whereas remplissage fill-in the humeral lesion so that it does not engage. In the setting of a Hill-Sachs lesion with little or no glenoid bone loss, remplissage has demonstrated satisfactory outcomes with a low complications and recurrence rate. Favorable results have been reported with glenoid bone grafting when managing isolated Hill-Sachs or bipolar lesions. Studies analyzing Latarjet and Eden-Hybinette procedures show that both procedures are safe and effective in the management of anterior glenohumeral instability. Attention should be paid to those patients with large bone defects not amenable to be restored with an isolated Latarjet that may be better addressed with an Eden-Hybinnete or adding a remplissage to the Latarjet procedure.

Abstract
BACKGROUND As an alternative to the Latarjet procedure, the arthroscopic free bone block (FBB) procedure combined with dynamic anterior stabilization (DAS) has been recently proposed to provide both glenoid augmentation and a tendon sling effect for treating anterior shoulder instability (ASI) with glenoid bone loss. PURPOSE To evaluate the clinical and radiological outcomes of FBB-DAS for ASI with glenoid bone loss. STUDY DESIGN Case series; Level of evidence, 4. METHODS Patients who underwent arthroscopic FBB-DAS for ASI with >15% glenoid bone loss between February 2017 and March 2020 were screened and enrolled in this study. Clinical outcome measures were assessed preoperatively and at a minimum 2-year follow-up, including recurrence, complications, shoulder functional scores, range of motion, and return to sports. Postoperative computed tomography and magnetic resonance imaging were also performed. RESULTS Of a total of 65 patients with a mean follow-up of 46.1 ± 13.1 months, no patients experienced a recurrent dislocation or subluxation postoperatively, while 2 had a positive anterior apprehension test (3.1%). Additionally, 2 patients (3.1%) experienced complications of hematoma and shoulder stiffness, respectively. The mean visual analog scale score, American Shoulder and Elbow Surgeons score, Rowe score, and Oxford Shoulder Instability Score all improved significantly from 3.2 ± 2.4, 75.0 ± 18.9, 43.6 ± 27.3, and 33.8 ± 9.0 preoperatively to 1.3 ± 0.8, 95.1 ± 8.0, 95.5 ± 7.8, and 14.8 ± 3.5 at final follow-up, respectively (all P < .001). No difference was detected in range of motion except for 8.1° and 7.5° external rotation limitations in adduction and abduction, respectively. There were 62 patients (95.4%) who returned to sports, and 54 patients (83.1%) returned to the preinjury level. The transferred biceps tendon was intact in all 59 patients who completed radiological examination at the latest follow-up. Good bone healing was achieved in 98.3% of patients, and the glenoid bone defect decreased from 18.1% to 4.9%. Osseous and labral glenoids were significantly enlarged in width and depth on the latest magnetic resonance imaging (all P < .001). CONCLUSION Arthroscopic FBB-DAS provided satisfactory clinical and radiological outcomes for ASI with glenoid bone loss. Despite slight external rotation restrictions, it achieved low recurrence and complication rates, excellent shoulder functional scores, a high return-to-sports rate, and favorable graft healing and remodeling.

Abstract
Latarjet modifies the anatomy of the shoulder, and subsequent revision surgery is challenging. It is mandatory to determine the cause of recurrence in order to select the best treatment option. A CT scan is needed to measure glenoid track and evaluate coracoid graft status: position, degree of consolidation, and osteolysis. Conservative management can be advocated in selected patients in whom the instability level does not interfere with the activities they wish to perform. Surgical treatment is based on the glenoid track measurement and coracoid graft suitability. The coracoid graft is considered suitable if it preserves the conjoint tendon insertion, does not show osteolysis, and is large enough to reconstruct the glenoid surface. Adding a remplissage is recommended for those cases with a coracoid graft insufficient to convert large off-track Hill-Sachs lesions into on-track. If the coracoid graft is suitable to reconstruct bone defects in terms of size and viability but is poorly positioned or avulsed, graft repositioning can be a valid option. In patients with unsuitable coracoid bone graft, free bone graft is the revision technique of choice. The size of the graft should be large enough to restore the glenoid surface and to convert any off-track Hill-Sachs lesion into on-track. There is a small group of patients in whom bone defects were properly addressed but Latarjet failed due to hyperlaxity or poor soft tissue quality. Extraarticular capsular reinforcement is suggested in this population.

Abstract
The optimal treatment for recurrent glenohumeral instability is a subject under debate. The recently described arthroscopic technique for dynamic anterior stabilization (DAS) fills the treatment indication gap between reconstructive bony procedures and soft tissue stabilization. However, indications for DAS are considered limited or not appropriate for patients with recurrent shoulder dislocations caused by severe bone defects. In this Technical Note, we present a modified all-arthroscopic DAS technique with added infraspinatus and posterior capsule remplissage to correct the extra-articular Hill-Sachs defect in a patient with recurrent dislocations and off-track bony lesions. The patient requested an alternative treatment option, other than the complication-prone Latarjet procedure.

Abstract
PURPOSE The aim of the current study was to compare the diagnostic precision and reliability of different methods in measuring Hill-Sachs lesions (HSLs) using MRI and CT. METHODS A total of 80 consecutive patients with a history of anterior shoulder instability were retrospectively included. The preoperative CT and MRI scans of the affected shoulders were analysed. To investigate the ability of the Franceschi grading, Calandra classification, Richards, Hall, and Rowe grading scale, Flatow percentage and "glenoid track" assessment according to Di Giacomo et al. to quantify the extent of humeral bone loss, the results of each measurement method obtained with MRI were compared with those achieved with CT. In addition, the intra- and inter-rater reliabilities of each measurement method using CT and MRI were calculated and compared. RESULTS A significant difference was found between CT and MRI in the determination of the Hill-Sachs interval (HSI) (p = 0.016), but not between the results of any of the other measurement techniques. With the exceptions of the Franceschi grade and Calandra classification, all measurement methods showed good or excellent intra- and inter-rater reliabilities for both MRI and CT. CONCLUSIONS While the determination of the HSI with MRI was more accurate, all other analysed techniques for measuring the amount of humeral bone loss showed similar diagnostic precision. With regard to the intra- and inter-rater reliabilities, all measurement techniques analysed, with the exception of the Franceschi and Calandra classifications, provided good to very good reliabilities with both CT and MRI.
