Abstract
The indications for bone block augmentation of the glenoid following recurrent anterior shoulder instability are expanding. Arthroscopic anatomic glenoid reconstruction (AAGR) is an evolving technique with similar clinical results to the Latarjet procedure and other open bone block procedures. Multiple types of bone grafts and fixation techniques have been described, with varying results on bony integration, resorption, articular congruity, and recurrence rates. This review focuses on biomechanics, patient workup, indications, current evidence, and the authors' preferred surgical technique for AAGR.

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).

J Shoulder Elbow Surg 2024:S1058-2746(24)00394-X. [PMID: 38825225 DOI: 10.1016/j.jse.2024.04.005] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/02/2024] [Revised: 03/28/2024] [Accepted: 04/08/2024] [Indexed: 06/04/2024]
Abstract
BACKGROUND The purpose of this study was to assess the clinical and radiographic outcomes of arthroscopic anatomic glenoid reconstruction (AAGR) used for primary vs. revision surgery for addressing anterior shoulder instability with bone loss. METHODS We performed a retrospective review on consecutive patients who underwent AAGR from 2012 to 2020. Patients who received AAGR for anterior shoulder instability with bone loss and had a minimum follow-up of 2 years were included. Exclusion criteria included patients with incomplete primary patient-reported outcome scores (PROs), multidirectional instability, glenoid fracture, nonrigid fixation and concomitant humeral avulsion of the glenohumeral ligament, or rotator cuff repair. Our primary outcome was measured using the Western Ontario Shoulder Instability Index (WOSI) scores. Secondary outcomes included postoperative Disabilities of the Arm, Shoulder, and Hand questionnaire (DASH) scores, complications, recurrence of instability and computed tomographic (CT) evaluation of graft position, resorption, and healing. RESULTS There were 73 patients (52 primary and 21 revision) finally included. Both groups had comparable demographics and preoperative WOSI and DASH scores. The primary group had significantly better postoperative WOSI and DASH scores at final follow-up when compared to the revision group (WOSI: 21.0 vs. 33.8, P = .019; DASH: 7.3 vs. 17.2, P = .001). The primary group also showed significantly better WOSI scores than the revision group at the 6-month, 1-year, and 2-year time points (P = .029, .022, and .003, respectively). The overall complication rate was 9.6% (5 of 52) in the primary group and 23.8% (5 of 21) in the revision group. Both groups showed good graft healing and placement in the anterior-to-posterior and mediolateral orientation and had a similar rate of graft resorption and remodeling. There was no difference between the groups in the remainder of the CT measurements. CONCLUSION Functional outcome scores and stiffness were significantly worse in patients undergoing an AAGR procedure after a failed instability surgery when compared with patients undergoing primary AAGR. There were no differences in postoperative recurrence of instability or radiographic outcomes. As a result, AAGR should be considered as a primary treatment option within current treatment algorithms for shoulder instability.

Remodeling process and clinical outcomes following all-arthroscopic modified Eden-Hybinette procedure using iliac crest autograft and 1-tunnel double Endobutton fixation system. J Shoulder Elbow Surg 2023; 32:1825-1837. [PMID: 36907316 DOI: 10.1016/j.jse.2023.01.041] [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: 08/15/2022] [Revised: 01/25/2023] [Accepted: 01/27/2023] [Indexed: 03/14/2023]
Abstract
BACKGROUND Arthroscopically modified Eden-Hybinette procedures for glenohumeral stabilization have been used for a long time. With the advancement of arthroscopic techniques and the development of sophisticated instruments, a double Endobutton fixation system has been used clinically to secure bone graft to the glenoid rim placed through a specifically designed guide. The purpose of this report was to evaluate clinical outcomes and serial glenoid remodeling process following all-arthroscopic anatomical glenoid reconstruction using autologous iliac crest bone grafting technique through 1-tunnel fixation. METHODS Forty-six patients with recurrent anterior dislocations and significant glenoid defects greater than 20% underwent arthroscopic surgery with a modified Eden-Hybinette technique. Instead of firm fixation, autologous iliac bone graft was fixed to the glenoid by double Endobutton fixation system through 1-tunnel placed in the glenoid surface. Follow-up examinations were performed at 3, 6, 12, and 24 months. The patients were followed up for a minimum of two years using the Rowe score, the Constant score, the Subjective Shoulder Value, and the Walch-Duplay score; patient satisfaction with the procedure outcome was also rated. Graft positions, healing, and absorption were evaluated postoperatively with computed tomography imaging. RESULTS At a mean follow-up of 28 months, all patients were satisfied and had a stable shoulder. The Constant score improved from 82.9 to 88.9 points (P < .001), the Rowe score, improved from 25.3 to 89.1 points (P < .001), the Subjective Shoulder Value improved from 31% to 87% (P < .001), and the Walch-Duplay score improved from 52.5 to 85.7 points (P < .001). One donor-site fracture occurred during the follow-up period. All grafts were well-positioned and achieved optimal bone healing with zero excessive absorption. The preoperative glenoid surface (72.6% ± 4.5%) increased significantly immediately after surgery to 116.5% ± 9.6% (P < .001). After a physiological remodeling process, the glenoid surface remained significantly increased at the last follow-up (99.2% ± 7.1%) (P < .001). The glenoid surface area appeared to decrease serially when compared between the first 6 months and 12 months postoperatively, while there was no significant interval change between 12 and 24 months postoperatively. CONCLUSION Patient outcomes were satisfactory following the all-arthroscopic modified Eden-Hybinette procedure using an autologous iliac crest grafting technique through one-tunnel fixation system with double Endobutton. Graft absorption mostly occurred on the edge and outside the ''best-fit'' circle of the glenoid. Glenoid remodeling occurred within the first year after all-arthroscopic glenoid reconstruction with an auto iliac bone graft.

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 To compare the functional outcomes, range of motion (ROM), recurrence rates, and complication rates of arthroscopic autologous iliac crest grafting (AICG) and Remplissage plus Bankart repair (RB) for anterior shoulder instability with bipolar bone defects. METHODS This study enrolled patients undergoing arthroscopic AICG or RB with 13.5-25% glenoid bone defect combined with Hill-Sachs lesion between January 2013 and April 2020, who had a minimum 2-year follow-up. Patient-reported outcomes were evaluated by Subjective Shoulder Value (SSV), Oxford Shoulder Instability Score (OSIS), Rowe score, Constant score, and visual analog scale (VAS) for pain. Active ROM, return to sports, recurrence, self-reported apprehension, and complications were recorded. RESULTS This study included 60 patients, including 28 AICG (Group A) and 32 RB (Group R). Mean glenoid bone defect was similar (17.7% ± 3.1% vs 16.6% ± 2.4%; P = .122). Both groups showed significant postoperative improvement in Rowe score, SSV, OSIS, and Constant score. No significant difference was found in postoperative Rowe Score (87.7 vs 85.2; P = .198). A total of 20/28 (71.4%) patients in Group A versus 26/32 (81.3%) patients in Group R met the Patient Acceptable Symptomatic State determined by VAS pain score (P = .370). Both groups showed high return-to-sports rates (67.8% vs 71.8%; P = .735) and slightly decreased ROM. There were two cases of recurrence in Group A versus one in Group R (P = .594). Group R had insignificantly higher positive self-reported apprehension rate (40.6% vs 17.9%; P = .055). CONCLUSION For anterior shoulder instability with bipolar bone defects, both arthroscopic AICG and RB can result in satisfactory clinical outcomes, good postoperative ROM, and low recurrence and complication rates. LEVEL OF EVIDENCE Level III; retrospective cohort study.

Abstract
Recurrent anterior shoulder dislocations accompanied by severe glenoid bone defects are typically treated with arthroscopy. Until now, autologous iliac grafting has been reported with excellent results, and different techniques of bone fixation have been introduced by numerous scholars. In this article, we introduce a specially designed guide that can achieve accurate positioning of the bone graft and a nonrigid graft fixation technique with a single EndoButton (Smith & Nephew). Using this technique, we greatly simplify the arthroscopic procedure and avoid the use of screws.

Abstract
INTRODUCTION With the help of a J-shaped bicortical iliac crest bone graft, the morphology of the glenoid can be augmented without having to use screws to achieve glenohumeral stability. The aim of this retrospective clinical study was to evaluate the clinical stability and function of the shoulder joint as well as the radiological remodelling process and arthropathic outcomes following the J-bone graft technique. MATERIALS AND METHODS 34 patients with recurrent shoulder dislocations and bony glenoid defects were treated with the J-bone graft technique between 2010 and 2018 at our level-I trauma centre. 15 patients (18 shoulders) could be recruited for the study. Pain levels, ASES, UCLA, SST, DASH, Rowe and WOSI Scores were collected using questionnaires. In 13 patients (16 shoulders) the Constant Score, ROM, CT with 3D reconstruction of the glenoid to assess the graft remodelling and X-rays were performed additionally. RESULTS None of the patients suffered subluxations or recurrent dislocations during the follow-up period. The overall complication rate was 11%. The evaluation using objective and subjective shoulder function scores yielded good-to-excellent results. Radiological assessment at follow-up showed a low rate of moderate-to-severe arthritis (12%) and a high rate of shoulders without any signs of arthritic degeneration (53%). The CT scans all revealed an almost complete restoration of the glenoid with none of the grafts being resorbed. A rise in the average glenoid circumference and glenoid area could be demonstrated between preoperative measurements (81.6 and 82.4%, respectively) and follow-up measurements (104 and 102.5%, respectively). CONCLUSION The results of this study show a successful stabilisation of the shoulder joint and a low complication rate following the J-bone graft technique. Remodelling of the bone graft could be demonstrated, which in turn led to an almost perfect glenoid surface area of 100%.

Abstract
Objective To evaluate the efficacy of the double‐row and double‐pulley technique in treating anterior shoulder glenoid fracture (Ideberg type Ia) using shoulder arthroscopy. Methods Thirty‐six patients with Ideberg type Ia admitted from March 1, 2017, to March 1, 2020, were retrospectively reviewed. Data of the patients' history included age, sex, side of the affected arm, the mean time from injury to surgery, the surgical duration, the average blood loss, and the average total duration of hospital stay. The double‐row and double‐pulley technique was used to repair the scapular glenoid fracture under arthroscopy. Computed tomography (CT) was used to evaluate fracture healing after surgery. The American Shoulder and Elbow Surgeons (ASES) score, the University of California at Los Angeles (UCLA) shoulder joint scoring system, and the Constant–Murley shoulder function score were used to assess the function of the affected shoulder. Results The surgical duration was 90–150 min, with a mean of 127 min. The average blood loss was 90 mL (range, 60–120 mL), and the average total duration of hospital stay was 9.2 days (range, 3 to 14 days). At 9 months after surgery, the CT results showed that all fractures healed, and all patients returned to their previous levels of activity and regained an excellent range of motion. The visual analog scale (VAS) score was 7.55 ± 1.32 before surgery, and the VAS score significantly decreased to 1.24 ± 0.72 at 12 months after the operation (p < 0.05). The Constant, ASES, and UCLA shoulder function scores were 44.38 ± 2.16, 43.47 ± 12.76, and 21.80 ± 1.16 before the surgery, respectively, which improved to 93.52 ± 2.82, 91.34 ± 8.28, and 33.24 ± 1.64, respectively, in the following 12 months. One patient experienced fat liquefaction. However, no cases of deep venous thrombosis, iatrogenic neurovascular compromise, wound infection, or neurovascular injury were identified. Conclusion The double‐row and double‐pulley technique for treating Ideberg type Ia under shoulder arthroscopy has minor surgical trauma, reliable fracture reduction and fixation, less postoperative pain, and fewer postoperative complications and significantly improves the patient's shoulder joint function.

Satisfactory Functional Results and Complication Rates After Anterior Glenoid Bone Block Reconstruction in Recurrent Shoulder Dislocation: A Mean 4-Year Follow-up Comparative Study. J ISAKOS 2022; 7:47-53. [PMID: 35561976 DOI: 10.1016/j.jisako.2022.04.009] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/28/2021] [Revised: 04/03/2022] [Accepted: 04/30/2022] [Indexed: 11/22/2022]
Abstract
BACKGROUND Anterior recurrent instability of the glenohumeral joint is a common clinical problem among the young population. Glenoid reconstruction with bone graft has become the treatment of choice, particularly in significant deficiency (˃ 20%). This study aims to assess the functional results of glenoid reconstruction using Latarjet and iliac bone graft in management of glenoid insufficiency associated with recurrent anterior dislocation of the glenohumeral joint. METHODS Patients suffering from anterior shoulder instability with glenoid defect > 20% were included in this study between 2016 and 2021. University of California at Los Angeles (UCLA) shoulder scale and Constant score were used to assess the functional improvement. Preoperative and final postoperative continuous outcomes were compared with one-tailed paired t-test and the outcomes across groups were compared using two-tailed independent t-test. P-value of < 0.05 was considered statistically significant for both tests. RESULTS This trial included 50 patients; twenty-five underwent mini-open Latarjet, and 25 underwent arthroscopic tricortical iliac bone grafting (ICBG). The mean follow-up durations were 50.1 ± 5.9 months for Laterjet and 51.6 ± 6.8 months for ICBG. Both techniques showed statistically significant improvement in the final UCLA (31.1± 2.1 in Laterjet, and 30.2± 2.2 in ICBG) and Constant (90.2± 4.6 in Laterjet, and 89± 5.01 in ICBG) scores. There was no statistically significant difference regarding mean age, sex, side of injury, mechanism of injury, follow-up period, and clinical outcome between both surgical treatments. At the end of the study, both groups demonstrated statistically significant improvement in the range of motion (p˂ 0.00001). Only one, non-adherent patient in Laterjet group had post-operative dislocation. In ICBG group, two patients had partial bone graft resorption, 3 graft site morbidities, and 1 hardware prominence. CONCLUSION Both Laterjet and iliac bone graft procedures had satisfactory functional results in reconstruction of glenoid defect > 20% in unstable shoulders with a mean 4-year follow-up. No statistically significant difference was reported in the last postoperative Constant and UCLA scores between both techniques, but Latarjet procedure had fewer complications (4%) than iliac bone grafting (24%).

J Shoulder Elbow Surg 2022; 31:e190-e208. [PMID: 34801716 DOI: 10.1016/j.jse.2021.10.023] [Citation(s) in RCA: 7] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/25/2021] [Revised: 10/08/2021] [Accepted: 10/23/2021] [Indexed: 02/01/2023]
Abstract
BACKGROUND Evidence on the efficacy and safety of the free bone grafting in treating anterior shoulder instability is limited. The purpose of this study was to systematically evaluate the clinical and imaging results of free bone grafting in treating anterior shoulder instability with glenoid bone defect and to explore the incidence of complications in clinically relevant subgroups. METHODS This systematic review was conducted per PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-analyses) guidelines. The PubMed, Embase, and Cochrane Library databases were searched up to January 29, 2021, for studies that had reported on free bone grafting in treating anterior shoulder instability with glenoid bone defect with a minimum of 1-year follow-up. Two researchers independently screened studies and extracted data. A random-effects model was used to pool data on clinical function scores, imaging results, and incidence of complications (recurrent instability and non-instability-related complications). Meta-regression analysis was used to evaluate the incidence of complications in different subgroups and investigate the sources of heterogeneity. RESULTS A total of 29 studies were included in the meta-analysis, comprising 840 patients (845 shoulders) with average ages ranging from 21 to 34.6 years. Compared with preoperatively, free bone grafting increased the postoperative Rowe score, American Shoulder and Elbow Surgeons score, Constant score, Subjective Shoulder Value, and Oxford Shoulder Instability Score by 53.16, 31.80, 20.81, 38.63, and 4.07 points, respectively, and reduced the visual analog scale pain score by 3 points on average. During the postoperative follow-up period, the rates of return to sport and return to preoperative levels were 84.2% and 73.1%, respectively. The imaging results showed that the free bone healing rate was 98.9% and the incidence of osteoarthritis was 10.9%. The incidence rates of recurrent instability and non-instability-related complications were 3.4% and 5.6%, respectively. Meta-regression analysis showed no evidence of effect modification by the year, follow-up time, proportion of male patients, autograft or allograft, and arthroscopy or open surgery on the incidence of complications. Subgroup analysis showed that the incidence rates of recurrent instability for open surgery, arthroscopy, allograft, autograft, Latarjet revision, and non-bone block revision were 4.1%, 2.3%, 1.5%, 4.4%, 10.3%, and 3.5%, respectively. CONCLUSION The application of free bone grafting in treating anterior shoulder instability with glenoid bone defect can effectively improve shoulder joint function and is associated with a high return-to-sport rate and a low overall recurrence rate, but there were some differences in the complications of recurrent instability and non-instability-related complications among the subgroups. Given that these results need to be confirmed via head-to-head comparisons, we recommend that future clinical and biomechanical studies focus on comparing and investigating the advantages and disadvantages of different surgical approaches, thus providing a basis for orthopedic surgeons to make reliable choices.

Anterior Shoulder Instability Part II-Latarjet, Remplissage, and Glenoid Bone-Grafting-An International Consensus Statement. Arthroscopy 2022; 38:224-233.e6. [PMID: 34332052 DOI: 10.1016/j.arthro.2021.07.023] [Citation(s) in RCA: 49] [Impact Index Per Article: 24.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/16/2021] [Revised: 07/06/2021] [Accepted: 07/13/2021] [Indexed: 02/02/2023]
Abstract
PURPOSE The purpose of this study was to establish consensus statements via a modified Delphi process on the Latarjet procedure, remplissage, and glenoid-bone grafting for anterior shoulder instability. METHODS A consensus process on the treatment utilizing 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 technical approaches identified in the statements on the Latarjet procedure and glenoid bone-graft were that a subscapularis split approach should be utilized, and that it is unclear whether a capsular repair is routinely required. Furthermore, despite similar indications, glenoid bone-grafting may be preferred over the Latarjet in patients with bone-loss greater than can be treated with a coracoid graft, and in cases of surgeon preference, failed prior Latarjet or glenoid bone-grafting procedure, and epilepsy. In contrast, the primary indications for a remplissage procedure was either an off-track or engaging Hill-Sachs lesion without severe glenoid bone loss. Additionally, in contrast to the bone-block procedure, complications following remplissage are rare, and loss of shoulder external rotation can be minimized by performing the tenodesis via the safe-zone and not over medializing the fixation. CONCLUSION Overall, 89% of statements reached unanimous or strong consensus. The statements that reached unanimous consensus were the prognostic factors that are important to consider in those undergoing a glenoid bone-grafting procedure including age, activity level, Hill-Sachs Lesion, extent of glenoid bone-loss, hyperlaxity, prior surgeries, and arthritic changes. Furthermore, there was unanimous agreement that it is unclear whether a capsular repair is routinely required with a glenoid bone graft, but it may be beneficial in some cases. There was no unanimous agreement on any aspect related to the Latarjet procedure or Remplissage. LEVEL OF EVIDENCE Level V, expert opinion.

Abstract
OBJECTIVE To evaluate the effectiveness of arthroscopic Pushlock anchor fixation with iliac creast bone autograft in the treatment of recurrent anterior shoulder instability with critical bone defect. METHODS The clinical data of 80 patients with recurrent anterior shoulder instability with critical bone defect treated by arthroscopic Pushlock anchor fixation with iliac creast bone autograft between January 2016 and January 2019 were retrospectively analyzed. The patients were all male; they were 18-45 years old at the surgery, with an average of 25 years old. The disease duration ranged from 3 months to 5 years, with an average of 2 years. The shoulder joint dislocated 3-50 times, with an average of 8 times. X-ray films, MRI, CT scans and three-dimensional reconstruction of the shoulder were performed before operation. The area of the anterior glenoid defect was 25%-45%, with an average of 27.3%. The shoulder mobility (forward flexion and external rotation in abduction at 90°), the Constant-Murley score, and the Rowe score were used to evaluate the shoulder function before operation and at last follow-up. RESULTS Patients were followed up 1-3 years, with an average of 2 years. No shoulder dislocation occurred again during follow-up. All partial graft absorption occurred after operation, CT scan showed that the graft absorption ratio was less than 30% at 1 week and 3 months after operation. CT three-dimensional reconstruction at 1 year after operation showed that all grafts had healed to the glenoid. The anterior glenoid bone defect was less than 5% (from 0 to 5%, with an average of 3.2%). At last follow-up, the shoulder mobility (forward flexion and external rotation in abduction at 90°), the Constant-Murley score, and the Rowe score significantly improved when compared with preoperative ones ( P<0.05). The shoulder mobility of external rotation in abduction at 90° of the affected side limited when compared with the healthy side [(6.7±5.1)°]. CONCLUSION Arthroscopic Pushlock anchor fixation with iliac creast bone autograft has a good effectiveness in the treatment of recurrent anterior shoulder instability with critical bone defect. The method is relatively simple and the learning curve is short.

Differences in Patients' and Surgeons' Expectations before Shoulder Stabilization Surgery. J Clin Med 2021; 10:jcm10204661. [PMID: 34682779 PMCID: PMC8538762 DOI: 10.3390/jcm10204661] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/06/2021] [Revised: 09/10/2021] [Accepted: 10/05/2021] [Indexed: 01/03/2023] Open
Abstract
Purpose: The primary goal of shoulder stabilization procedures is to re-establish stability and many surgeons measure the success after shoulder stabilization surgery only by the absence of re-dislocation. However, patients might also suffer from pain, loss of range of motion and strength as well as anxiety and stigmatization and therefore have other expectations from a stabilization surgery than just a stable shoulder. Purpose of this study was to analyze if surgeons know what their patients typically expect from a shoulder stabilization surgery. Furthermore, the aim was to analyze the influence of various factors on patients’ expectations. Materials and Methods: 204 patients with a diagnosis of shoulder instability scheduled for surgical treatment were included in this prospective multicentric study. Preoperatively, objective and subjective scores were obtained and patients were asked about their postoperative expectations. Additionally, 25 surgeons were interviewed with regard to what they think their patients expect from the surgery using standardized questions. Results: With regard to postoperative expectations surveyed by the Hospital for Special Surgery questionnaire (HSS), the most important goal to achieve for the patients was ‘stopping the shoulder from dislocation’, followed by ‘to improve the ability to exercise or participate in sports’ and ‘being the shoulder to be back the way it was before the issue started’. The ranking of factors for patients was ‘stability’ as the most important to achieve, followed by ‘movement’, ‘strength’, ‘pain’ and ‘cosmetics’. For surgeons, the order was ‘stability’ (p = 0.004 **), ‘movement’ (p = 0.225), ‘pain’ (p = 0.509), ‘strength’ (p = 0.007 **) and ‘cosmetics’ (p = 0.181). There was a significant difference between patients and surgeons with regard to gaining stability at the cost of movement (p = 0.001 **). Conclusion: Patients and surgeons expectations regarding outcome after surgical shoulder stabilization procedures are quite similar with limited topics of disagreement. Generally, surgeons tend to overrate the importance of stability at the costs of other factors.

Arthroscopic bone block stabilisation procedures for glenoid bone loss in anterior glenohumeral instability: A systematic review of clinical and radiological outcomes. Orthop Traumatol Surg Res 2021; 107:102949. [PMID: 33932578 DOI: 10.1016/j.otsr.2021.102949] [Citation(s) in RCA: 9] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/05/2020] [Revised: 01/27/2021] [Accepted: 02/12/2021] [Indexed: 02/03/2023]
Abstract
INTRODUCTION Recurrent shoulder instability is frequently associated with glenohumeral bone loss. Recently there has been a surge of interest in arthroscopically performed bone block procedures. The aim of this systematic review was to determine the clinical and radiological outcomes of arthroscopic glenoid bone block stabilisation for recurrent anterior dislocation. METHODS This systematic review was performed in accordance with PRISMA guidelines. The search strategy was applied to MEDLINE and Embase databases on 20th July 2020. Studies reporting either clinical or radiological outcomes following arthroscopic bone block stabilisation for recurrent anterior dislocation were included. Primary outcomes were function and instability scores. Secondary outcomes included recurrent instability, graft union and resorption rates, return to activity/sports, and complications. Pooled analysis was performed when an outcome was uniformly reported by more than one study. Critical appraisal of studies was conducted using the Methodological Index for Non-Randomized Studies (MINORS) tool. RESULTS Application of the search strategy resulted in the inclusion of 15 eligible studies; 12 used iliac crest bone graft while 3 used distal tibial allograft. The overall population comprised 265 patients (mean age range, 25.5-37.5 years; 79% of participants were men). All post-operative outcome scores were significantly improved, and the overall rate of recurrent instability was low (weighted mean 6.6%, range 0-18.2%) at mean follow up of 30.4 months. The Rowe score was the most frequently reported outcome measure, improving on average by 53.9 points at final follow-up, exceeding the minimal clinically important difference (MCID) threshold. Graft union rates ranged between 92-100% in 8 out of 10 studies at mean follow up range 6-78.7 months but two reported lower rates ranging from 58.3-84% for autografts and 37.5% for allografts. Graft resorption rates averaged between 10-16% for autografts and 32% for allografts. Hardware-related complications occurred in 2% with the most frequent being screw breakage or symptomatic mechanical irritation. CONCLUSION Arthroscopic bone block stabilisation is associated with high rates of graft union, significant improvements in the WOSI, Rowe, Constant and SSV scores (exceeding MCID thresholds where known), and a low rate of complications, including re-dislocation in the short to mid-term. Graft union rates were high, but the long-term implications of graft resorption (which occurs more frequently with allograft) are unknown. Longer follow-up of these patients and future experimental studies are required to further examine the effects of graft type and fixation methods. LEVEL OF EVIDENCE IV; systematic review.

Abstract
PURPOSE Glenoid augmentation using free bone blocks for anterior shoulder instability has been proposed as an alternative to or bail-out for the Latarjet procedure. The purpose of this investigation was to systematically review and compare outcomes of patients undergoing glenoid augmentation using free bone block autografts versus allografts. METHODS A systematic review using PubMed, MEDLINE, Embase, and the Cochrane Library databases was performed in line with the PRISMA statement. Studies reporting outcomes of patients treated with free bone block procedures for anterior shoulder instability with minimum 2-year follow-up were included. Random effects modelling was used to compare patient-reported outcomes, return to sports, recurrent instability, non-instability related complications, and development of arthritis between free bone block autografts and allografts. RESULTS Eighteen studies comprising of 623 patients met the inclusion criteria for this investigation. There were six studies reporting on the use of allografts (of these, two used distal tibial, three iliac crest, and one femoral head allograft) in 173 patients and twelve studies utilizing autografts (of these, ten used iliac crest and two used free coracoid autograft) in 450 patients. Mean age was 28.7 ± 4.1 years for the allograft group and 27.8 ± 3.8 years for the autograft group (n.s). Mean follow-up was 98 months in autograft studies and 50.8 months for allograft studies (range 24-444 months, n.s). Overall mean increase in Rowe score was 56.2 with comparable increases between autografts and allografts (n.s). Pooled recurrent instability rates were 3% (95% CI, 1-7%; I2 = 77%) and did not differ between the groups (n.s). Arthritic progression was evident in 11% of autografts (95% CI, 2-27%; I2 = 90%) and 1% (95% CI, 0-8%; I2 = 63%) of allografts (n.s). The overall incidence of non-instability related complications was 5% (95% CI, 2-10%; I2 = 81%) and was similar between the groups (n.s). Pooled return to sports rate was 88% (95% CI, 76-96%; I2 = 76%). CONCLUSION Glenoid augmentation using free bone block autograft or allograft in the setting of recurrent anterior shoulder instability with glenoid bone loss is effective and safe. Outcomes and complication incidence using autografts and allografts were comparable. Due to the high degree of heterogeneity in the data and outcomes reported in available studies, which consist primarily of retrospective case series, future prospective trials investigating long-term outcomes using free bone block autograft versus allograft for anterior shoulder instability with glenoid bone loss are warranted.

Abstract
Purpose To determine the definitions for recurrence used in the literature, assess the consensus in using these definitions, and determine the impact of these definitions on recurrence rates. Methods A literature search was performed in PubMed and EMBASE including studies from 2000 to 2020 reporting on recurrence rates after anterior arthroscopic shoulder instability surgery. Dislocation, apprehension, subluxation and recurrence rates were compared. Results Ninety-one studies were included. In 68% of the eligible studies, recurrence rates are not well defined. Thirty (33%) studies did not report on dislocations, 45 (49%) did not report on subluxations, and 58 (64%) did not report on apprehension. Seventeen different definitions for recurrence of instability, 4 definitions of dislocations, and 8 definitions of subluxation were used. Conclusion Recurrence rates are poorly specified and likely underreported in the literature, hampering comparison with results of other studies. This highlights the need for a consensus on definition of recurrence across shoulder instability studies. We recommend not using the definition recurrence of instability anymore. We endorse defining dislocations as a radiographically confirmed dislocation or a dislocation that is manually reduced, subluxations as the feeling of a dislocation that can be (spontaneously) reduced without the need for a radiographically confirmed dislocation, and a positive apprehension sign as fear of imminent dislocation when placing the arm in abduction and external rotation during physical examination. Reporting on the events resulting in a dislocation or subluxation aids in making an estimation of the severity of instability. Level of Evidence Level IV, systematic review.

Non-rigid fixation of the glenoid bone block for patients with recurrent anterior instability and major glenoid bone loss: A systematic review. Shoulder Elbow 2021; 13:168-180. [PMID: 33897848 PMCID: PMC8039760 DOI: 10.1177/1758573219872512] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/07/2019] [Revised: 06/05/2019] [Accepted: 07/29/2019] [Indexed: 11/17/2022]
Abstract
BACKGROUND New types of glenoid bone block fixation, involving suture buttons, suture anchors or even implant-free impaction of the graft, have been recently introduced. In contrast to screws which allow for a rigid fixation of the bone block, these alternative procedures provide a non-rigid type of fixation. METHODS Two reviewers independently conducted the search in a systematic way (according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) using the MEDLINE/PubMed database and the Cochrane Database of Systematic Reviews. These databases were queried with the terms "Latarjet" OR "Eden-Hybbinette" OR "bone block" AND "anterior" AND "shoulder" AND "instability." RESULTS Eight out of the 325 initial studies were finally chosen according to our inclusion-exclusion criteria. In total, 750 patients were included in this review. The overall anterior instability recurrence rate for patients treated with non-rigid fixation was 2.6%, while the overall rate of non-union or graft osteolysis was 5.4%. CONCLUSIONS Regardless of the graft type, bone block non-rigid fixation showed satisfactory clinical and functional outcomes for the treatment of anterior shoulder instability with substantial glenoid bone deficiency. Furthermore, non-rigid fixation resulted in adequate bone graft healing and osseous incorporation. Lastly, given the relative lack of data, further prospective controlled studies are required to assess bone block non-rigid fixation procedures in comparison with the traditional rigid (with screws) fixation techniques.

Abstract
BACKGROUND Free bone block (FBB) procedures for anterior shoulder instability have been proposed as an alternative to or bail-out for the Latarjet procedure. However, studies comparing the outcomes of these treatment modalities are limited. PURPOSE To systematically review and perform a meta-analysis comparing the clinical outcomes of patients undergoing anterior shoulder stabilization with a Latarjet or FBB procedure. STUDY DESIGN Systematic review and meta-analysis; Level of evidence, 4. METHODS PubMed, Embase, and the Cochrane Library databases were systematically searched from inception to 2019 for human-participants studies published in the English language. The search was performed according to the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) statement including studies reporting clinical outcomes of patients undergoing Latarjet or FBB procedures for anterior shoulder instability with minimum 2-year follow-up. Case reports and technique articles were excluded. Data were synthesized, and a random effects meta-analysis was performed to determine the proportions of recurrent instability, other complications, progression of osteoarthritis, return to sports, and patient-reported outcome (PRO) improvement. RESULTS A total of 2007 studies were screened; of these, 70 studies met the inclusion criteria and were included in the meta-analysis. These studies reported outcomes on a total of 4540 shoulders, of which 3917 were treated with a Latarjet procedure and 623 were treated with an FBB stabilization procedure. Weighted mean follow-up was 75.8 months (range, 24-420 months) for the Latarjet group and 92.3 months (range, 24-444 months) for the FBB group. No significant differences were found between the Latarjet and the FBB groups in the overall random pooled summary estimate of the rate of recurrent instability (5% vs 3%, respectively; P = .09), other complications (4% vs 5%, respectively; P = .892), progression of osteoarthritis (12% vs 4%, respectively; P = .077), and return to sports (73% vs 88%; respectively, P = .066). American Shoulder and Elbow Surgeons scores improved after both Latarjet and FBB, with a significantly greater increase after FBB procedures (10.44 for Latarjet vs 32.86 for FBB; P = .006). Other recorded PRO scores improved in all studies, with no significant difference between groups. CONCLUSION Current evidence supports the safety and efficacy of both the Latarjet and FBB procedures for anterior shoulder stabilization in the presence of glenoid bone loss. We found no significant differences between the procedures in rates of recurrent instability, other complications, osteoarthritis progression, and return to sports. Significant improvement in PROs was demonstrated for both groups. Significant heterogeneity existed between studies on outcomes of the Latarjet and FBB procedures, warranting future high-quality, comparative studies.

Abstract
PURPOSE To evaluate the clinical, functional, and radiological midterm outcomes of the all-arthroscopic modified Eden-Hybinette procedure in patients with recurrent anterior shoulder instability. METHODS A retrospective, single-center case series with prospectively collected data was conducted. The inclusion criterion was traumatic recurrent anterior shoulder instability with significant glenoid bone loss; patients with atraumatic or multidirectional instability were excluded. An all-arthroscopic modified Eden-Hybinette procedure using iliac crest autograft and double-pair button fixation was carried out. All patients were postoperatively assessed for recurrence and apprehension. Shoulder range of motion values and functional scores, including American Shoulder and Elbow Surgeons Score, Oxford instability, Rowe instability, and Walch-Dupplay, were recorded. Graft positions, healing, and absorption were evaluated with computed tomography. Comparisons of values were performed with paired t tests for normally distributed differences and with nonparametric Wilcoxon's signed rank test otherwise. RESULTS The final study cohort included 28 patients, mean age 36 ± 10 years, and mean follow-up period 43 ± 6 months (range 36 to 53). Median glenoid bone loss was 12.4% (range 8% to 33%). No recurrence occurred, no subjective shoulder instability was reported, and no major complications were documented through the last follow-up. Postoperative shoulder range of motion had no significant differences compared with the healthy side. All final postoperative functional scores significantly increased to show excellent results compared with preoperative values. All grafts were positioned and healed optimally, and none was completely reabsorbed. CONCLUSIONS The all-arthroscopic modified Eden-Hybinette procedure is safe, leading to excellent clinical and radiological midterm outcomes in patients with recurrent anterior shoulder instability. This technique restores glenoid bone defects and preserves the normal shoulder anatomy. LEVEL OF EVIDENCE IV, therapeutic, retrospective case series.

Abstract
Massive glenoid bone loss in recurrent anterior instability of the shoulder represents a surgical challenge. Some clinical trials have been published assessing the role of arthroscopic iliac crest bone grafting techniques for the management of recurrent anterior instability with glenoid bone loss. However, bone graft fixation is still controversial. We developed a method for anatomic reconstruction of anterior glenoid bone defects using autologous iliac crest graft. This technique is based on the assumption that anatomic restoration of glenoid depth and width is essential to restore stability to the shoulder.

Abstract
PURPOSE To investigate the clinical and radiologic mid- to long-term results of arthroscopic iliac crest bone-grafting for anatomic glenoid reconstruction in patients with recurrent anterior shoulder instability. METHODS Seventeen patients were evaluated after a minimum follow-up of 5 years. Clinical [range of motion, subscapularis tests, apprehension sign, Subjective Shoulder Value (SSV), Constant Score (CS), Rowe Score (RS), Walch Duplay Score (WD), Western Ontario Shoulder Instability Index (WOSI)], and radiologic [X-ray (true a.p., Bernageau and axillary views) and computed tomography (CT)] outcome parameters were assessed. RESULTS Fourteen patients [mean age 31.1 (range 18-50) years] were available after a follow-up period of 78.7 (range 60-110) months. The SSV averaged 87 (range 65-100) %, CS 94 (range 83-100) points, RS 89 (range 30-100) points, WD 87 (range 25-100) points, and WOSI 70 (range 47-87) %. The apprehension sign was positive in two patients (14%). One patient required an arthroscopic capsular plication due to a persisting feeling of instability, while the second patient experienced recurrent dislocations after a trauma, but refused revision surgery. CT imaging showed a significant increase of the glenoid index from preoperative 0.8 ± 0.04 (range 0.7-0.8) to 1.0 ± 0.11 (range 0.8-1.2) at the final follow-up (p < 0.01). CONCLUSION Arthroscopic reconstruction of anteroinferior glenoid defects using an autologous iliac crest bone-grafting technique yields satisfying clinical and radiologic results after a mid- to long-term follow-up period. Postoperative re-dislocation was experienced in one (7.1%) of the patients due to a trauma and an anatomic reconstruction of the pear-shaped glenoid configuration was observed. LEVEL OF EVIDENCE IV.

Orthop J Sports Med 2020; 8:2325967120958007. [PMID: 33110928 PMCID: PMC7564622 DOI: 10.1177/2325967120958007] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/08/2020] [Accepted: 07/29/2020] [Indexed: 11/30/2022] Open
Abstract
Background: Although clinical outcome scores are comparable after coracoid transfer
procedure (Latarjet) and iliac crest bone graft transfer (ICBGT) for
anterior shoulder instability with glenoid bone loss, a significant decrease
in internal rotation capacity has been reported for the Latarjet
procedure. Hypothesis: The subscapularis (SSC) musculotendinous integrity will be less compromised
by ICBGT than by the Latarjet procedure. Study Design: Cohort study; Level of evidence, 3. Methods: We retrospectively analyzed pre- and postoperative computed tomography (CT)
scans at short-term follow-up of 52 patients (26 Latarjet, 26 ICBGT)
previously assessed in a prospective randomized controlled trial.
Measurements included the preoperative glenoid defect area and graft area
protruding the glenoid rim at follow-up and tendon thickness assessed
through SSC and infraspinatus (ISP) ratios. Fatty muscle infiltration was
graded according to Goutallier, quantified with muscle attenuation in
Hounsfield units, and additionally calculated as percentages. We measured 3
angles to describe rerouting of the SSC musculotendinous unit around the
bone grafts. Results: SSC fatty muscle infiltration was 2.0% ± 2.2% in the Latarjet group versus
2.4% ± 2.2% in ICBGT (P = .546) preoperatively and showed
significantly higher values in the Latarjet group at follow-up (5.3% ± 4.5%
vs 2.3% ± 1.7%; P = .001). In total, 4 patients (15.4%) in
the Latarjet group showed a progression from grade 0 to grade 1 at
follow-up, whereas no changes in the ICBGT group were noted. The measured
rerouting angle of the SSC muscle was significantly increased in the
Latarjet group (11.8° ± 2.1°) compared with ICBGT (7.5° ± 1.3°;
P < .001) at follow-up, with a significant positive
correlation between this angle and fatty muscle infiltration
(R = 0.447; P = .008). Ratios of
SSC/ISP tendon thickness were 1.03 ± 0.3 in the Latarjet group versus 0.97 ±
0.3 (P = .383) in ICBGT preoperatively and showed
significantly lower ratios in the Latarjet group (0.7 ± 0.3 vs 1.0 ± 0.2;
P < .001) at follow-up. Conclusion: Although clinical outcome scores after anterior shoulder stabilization with a
Latarjet procedure and ICBGT are comparable, this study shows that the
described decline in internal rotation capacity after Latarjet procedure has
a radiographic structural correlate in terms of marked thinning and
rerouting of the SSC tendon as well as slight fatty degeneration of the
muscle.

Benefits of bone graft augmentation to arthroscopic Bankart repair for recurrent anterior shoulder instability with glenoid bone loss. Knee Surg Sports Traumatol Arthrosc 2020; 28:2325-2333. [PMID: 31667568 DOI: 10.1007/s00167-019-05746-2] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/01/2018] [Accepted: 10/09/2019] [Indexed: 10/25/2022]
Abstract
PURPOSE Glenoid bone loss contributes to recurrent instability after arthroscopic Bankart repair alone. With significant glenoid bone loss, better results have been reported after arthroscopic Bankart repair with glenoid arc reconstruction. However, no reports compare augmentation using bone graft with non-augmentation for glenoid bone loss. The purpose of this study was to assess clinical results of an arthroscopic Bankart repair with or without arthroscopic bone graft augmentation. It was hypothesized that such bone graft augmentation would restore shoulder stability, and lead to excellent outcomes. METHODS Of 552 patients treated for anterior glenohumeral instability with arthroscopic Bankart repair, 68 met this study's inclusion criteria of glenoid bone loss over 20% and follow-up of at least 2 years. Patients were divided into 2 groups based on whether with bone graft augmentation for glenoid bone loss [Group A: n = 35, median age; 21 years (range 13-72 years)], or not (Group B: n = 33, median age; 21 years (range 13-50 years)]. For grafting, either autologous iliac bone or artificial bone made of hydroxyapatite was used. Rowe score, recurrence rate, and return to sport were used to assess the results. RESULTS Mean Rowe score was 95.0 (SD 10.6) in Group A and 69.7 (SD 27.2) in Group B (p < 0.05). The recurrence rate was 2.9% (1/36) in Group A and 48.5% (16/33) in Group B (p < 0.05). Regarding contact/collision athletes, 24 were contained in Group A and 22 in Group B. Of the patients with recurrence in Group B, 13 (59.1%) were contact/collision athletes. Finally, 50% of the contact/collision sports athletes for both groups returned to their sports at the same as pre-injury level. Of the 11 patients who returned to the same level of contact/collision sports in Group B, seven returned with residual instability. Nine athletes in Group A and 3 in Group B quit their sports for personal or social reasons. CONCLUSIONS Bone graft augmentation was beneficial when used with Arthroscopic Bankart repair for recurrent anterior shoulder instability with glenoid bone loss. Especially, for recurrent anterior shoulder instability with glenoid bone loss in contact/collision sports athletes, bone graft augmentation should be strongly considered as beneficial.

Abstract
INTRODUCTION Donor site morbidity constitutes the most prevalent source of complications during anatomic glenoid reconstruction. Therefore, the aim of this study was to evaluate the clinical and radiologic results of arthroscopic anatomic glenoid reconstruction using an allogenic, tricortical iliac crest bone graft for glenoid bone loss in recurrent anterior shoulder instability. MATERIALS AND METHODS Ten patients [one female/nine male, mean age 31.9 years (range, 26-40)] underwent allogenic iliac crest bone grafting and were evaluated clinically [range of motion, subscapularis tests, apprehension sign, Constant score (CS), Rowe score (RS), Walch-Duplay score (WD), Western Ontario Shoulder Instability Index (WOSI), Subjective Shoulder Value (SSV)] and radiographically [3-dimensional computed tomography (CT) scans]. RESULTS After 23.2 months, the CS averaged 90 points (range, 84-98), RS 83 points (range, 50-100), WD 81 points (range, 50-100), WOSI 72% (range, 41-86) and the SSV 83% (range, 70-95). All patients showed a free range of motion and intact subscapularis muscle function. The apprehension sign was positive in three patients (30%) with a recurrent subluxation in one patient (10%). The glenoid surface area increased significantly from 84.4% (range, 73.5-92.1) preoperatively to 118.4% (range, 105.6-131.2) after surgery, while the glenoid defect was significantly reduced from 16.2% (range, 9.2-26.5) to 0.6% (range, 0-1.6). One year postoperative, total resorption of the allografts was observed with a glenoid surface area of 86.6% (range, 76.4-98.0) and corresponding increase of the glenoid defect to 14.0% (range, 2.9-23.6). CONCLUSION Arthroscopic glenoid reconstruction using an iliac crest bone allograft achieves satisfactory clinical results and glenohumeral stability during a short-term follow-up. However, this procedure was not observed to accomplish an anatomic reconstruction of the glenoid concavity due to excessive graft resorption.

Abstract
Objective Atrophic distal femur non-union with bone defect (ADFNBD) has been a worldwide challenge to treat due to the associated biological and mechanical problems. The purpose of this study was to introduce a new solution involving the use of a J-shaped iliac crest bone graft (J-bone) combined with double-plate (DP) in the treatment of femoral non-union. Methods Clinically, 18 patients with ADFNBD were included in this retrospective study and were treated with a combination of J-bone graft and DP. The average follow-up time was 22.1 ± 5.5 months (range, 14 to 34 months). The imaging information and knee joint activity tests and scores were used to evaluate the time to weight-bearing, the time to non-union healing, and the knee joint mobility. A finite element analysis was used to evaluate the differences between the following: (1) the use of a lateral locking plate (LLP) only group (LLP-only), (2) a DP only group (DP-only), (3) a DP with a J-bone group (DP+J-bone), and (4) an LLP with a J-bone group (LLP+J-bone) in the treatment of ADFNBD. A finite element analysis ABAQUS 6.14 (Dassault systems, USA) was used to simulate the von Mises stress distribution and model displacement of the plate during standing and normal walking. Result All patients with non-union and bone defect in the distal femur achieved bone healing at an average of 22.1 ± 5.5 months (range, 14 to 34 months) postoperatively. The average healing time was 6.72 ± 2.80 months. The knee Lysholm score was significantly improved compared with that before surgery. Under both 750 N and 1800 N axial stress, the maximum stress with the DP+J-bone structure was less than that of the LLP+J-bone and DP-only structures, and the maximum stress of J-bone in the DP+J-bone was significantly less than that of the LLP+J-bone+on structure. The fracture displacement of the DP+J-bone structure was also smaller than that of the LLP+J-bone and DP-only structures. Conclusion J-bone combined with DP resulted in less maximum stress and less displacement than did a J-bone combined with an LLP or a DP-only graft for the treatment of ADFNBD. This procedure was associated with less surgical trauma, early rehabilitation exercise after surgery, a high bone healing rate, and a satisfactory rate of functional recovery. Therefore, a combination of J-bone and DP is an effective and important choice for the treatment of ADFNBD.

Abstract
BACKGROUND A number of clinical trials have been published assessing the role of iliac crest bone grafting for the management of recurrent anterior instability with glenoid bone loss in contemporary practice. We therefore performed a systematic review of contemporary literature to examine the effect of iliac crest bone grafting on postoperative outcomes of these patients. Our hypothesis is that contemporary iliac crest bone block techniques are associated with low reoperation and complication rates combined with satisfactory functional results. METHODS The US National Library of Medicine (PubMed/MEDLINE), the Cochrane Database of Systematic Reviews, and EMBASE were searched between January 2008 and December 2019 for relevant publications. RESULTS Following the application of the inclusion-exclusion criteria, nine articles were found eligible for our analysis. In total, 261 patients (mean age range, 25.5-37.5 years; mean follow-up range, 20.6-42 months) were included in the studies of the current review. The mean modified Coleman score was 48.6 (range 37-65), indicating an overall low-to-moderate methodological quality. In the short term, the overall all-cause reoperation rate was 6.1%, while the rate of recurrent instability was 4.8%. The graft non-union rate was 2.2%, while the rate of osteolysis, graft fracture, and infection was 0.4%, 0.9%, and 1.7%, respectively. Finally, hardware-related complications, such as screw breakage or symptomatic mechanical irritation around the screw insertion, occurred in 3.9% of the patients. CONCLUSIONS Iliac crest bone block techniques in contemporary practice are safe and effective in the short-term (< 4 years) follow-up for the management of anterior shoulder instability with substantial glenoid bone deficiency. However, further studies of higher quality and longer follow-up are required to establish the therapeutic value of these techniques as well as to clarify whether there are differences in the outcomes of arthroscopic and open iliac crest bone block procedures.

Abstract
Anterior shoulder instability is commonly associated with injuries to the labrocapsular structures of the glenohumeral joint and with osseous glenoid defects of varying degree. If the bone defect exceeds a clinically relevant threshold, mere soft-tissue repairs result in high rates of recurrent instability and the glenoid needs to be reconstructed with osseous augmentation. The most popular techniques for glenoid reconstruction include variations of coracoid transfer or bone-block procedures; however, these procedures are not free from risks and complications, which are often related to the method of fixation1. An alternative to the widely used coracoid transfer variations or bone-block procedures is anatomic implant-free glenoid reconstruction with a J-shaped iliac-crest bone graft. After press-fit fixation, the graft undergoes a physiological remodeling process resulting in the restoration of native scapular neck morphology. Although not as widely known, the open J-bone-graft procedure has been successfully used for the treatment of glenoid bone loss for nearly 3 decades2-4. The arthroscopic J-bone-graft technique represents an innovative advancement of the open procedure. Early to midterm follow-up of the arthroscopic J-bone-graft technique has revealed excellent clinical results1. Description The major steps of the procedure, which are demonstrated in the present video article, include (1) detachment of the labrocapsular ligamentous complex and preparation of the anterior aspect of the glenoid, (2) establishment of a deep anterior-inferior portal and splitting of the subscapularis tendon, (3) introduction of the "waterslide," (4) osteotomy at the scapular neck 30° relative to the glenoid surface and trial impaction, (5 and 6) harvesting and preparation of a J-shaped bicortical iliac-crest bone graft, (7) press-fit impaction of the bone graft in the prepared osteotomy over the "waterslide", and (8) capsuloligamentous repair over the graft. Alternatives Coracoid transfer (Latarjet-Bristow), iliac-crest bone-grafting, and distal tibial allograft. Rationale Although widely in use, nonanatomic coracoid transfer procedures or bone-block techniques relying on hardware fixation are associated with specific complications, including nonunion, osteolysis, coracoid fractures, hardware complications, and difficult revision1. Many of these disadvantages can be avoided by the use of anatomic implant-free glenoid reconstruction with a J-shaped iliac-crest bone graft. After press-fit fixation, the graft undergoes a physiological remodeling process that follows the law of bone adaptation to mechanical stresses described by Wolff, which ultimately results in the restoration of a nearly native anterior scapular neck morphology4. The open version of this technique has been successfully used for over 3 decades. The arthroscopic, minimally invasive variation of the J-bone-graft technique presented in this video article represents a further advancement of the anatomic nature of the procedure. Expected Outcomes The arthroscopic implant-free J-bone-graft technique is an alternative to other procedures widely used for the treatment of anterior glenoid bone defects. The main advantage of this technique is the avoidance of severe complications that arise from the nonanatomic reconstruction and fixation methods found with other procedures1. Early to midterm follow-up of the arthroscopic J-bone-graft technique has revealed excellent clinical results, and the traditional open technique has been in use successfully for over 3 decades2-5. Previous patients have been able to return to a variety of occupational and athletic activities including overhead, throwing, and contact sports. Return to daily living and to moderate athletic activities is usually possible within 3 months. Return to competition is allowed after 6 months2-5. Important Tips •Avoid intraoperative graft fractures by applying strictly axial force during impaction.•Reduce the risk of glenoid fractures by performing an oblique osteotomy at an angle of 20° to 30° and 5 mm medial to the glenoid surface.•The postoperative physiological remodeling process determines ultimate graft fixation and glenohumeral stability. Keep this in mind when allowing return to activities.

[PMID: 31727586 DOI: 10.1016/j.otsr.2019.07.012] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/07/2019] [Revised: 05/06/2019] [Accepted: 07/16/2019] [Indexed: 02/02/2023]
Abstract
PURPOSE The purpose of this study was to evaluate sports ability and the rate of return to sports after implant-free iliac bone graft for recurrent, anterior shoulder instability and anterior glenoid bone loss. Subgroups of younger and older patients and patients who had previous arthroscopic Bankart surgery and those who did not have such surgery before implant-free iliac bone graft were formed and compared. METHODS We retrospectively analyzed 34 patients; 14 patients had previous arthroscopic Bankart surgery, and 20 patients did not have the surgery; The median age at the time of iliac bone graft was 35.3 years (range, 23 to 75), 17 patients were over the age of 35, and 17 patients were under the age of 35. The mean follow-up was 40 months (range: 25 to 56). RESULTS All the 34 patients were engaged in pre- and post-operative sport, which represents a return to sport rate of 100%. Although the number of sport disciplines decreased significantly from 6 before the operation to 4.8 after the operation (p=0.002), the number of sports sessions per week did not change significantly, and the duration per session did not change significantly. More than two-thirds of all patients returned to sports within 6 months. Overall, 41% of patients changed sport disciplines, 15% of whom cited shoulder-related causes; however, all patients returned to the same sport level. CONCLUSIONS Overall and within the subgroups, the return to sport rate after implant-free iliac bone grafting was high, with a high sense of well-being. The number of sport disciplines decreased significantly and more than one-third of the patients changed disciplines, of which 15% percent changed due to shoulder-related causes. The sport level remained equal, and no other parameters changed significantly compared with the time before the onset of restrictive shoulder symptoms.

Abstract
BACKGROUND The Latarjet and iliac crest bone graft transfer (ICBGT) procedures are competing treatment options for anterior shoulder instability with glenoid bone loss. METHODS In this bicentric prospective randomized study, 60 patients with anterior shoulder instability and glenoid bone loss were included and randomized to either an open Latarjet or open ICBGT (J-bone graft) procedure. Clinical evaluation was completed before surgery and 6, 12, and 24 months after surgery, including the Western Ontario Shoulder Instability index, Rowe score, Subjective Shoulder Value, pain level, satisfaction level, and work and sports impairment, as well as assessment of instability, range of motion, and strength. Adverse events were prospectively recorded. Radiographic evaluation included preoperative, postoperative, and follow-up computed tomography analysis. RESULTS None of the clinical scores showed a significant difference between the 2 groups (P > .05). Strength and range of motion showed no significant differences except for diminished internal rotation capacity in the Latarjet group at every follow-up time point (P < .05). A single postoperative traumatic subluxation event occurred in 2 ICBGT patients and 1 Latarjet patient. The type and severity of other adverse events were heterogeneous. Donor-site sensory disturbances were observed in 27% of the ICBGT patients. Computed tomography scans revealed a larger glenoid augmentation effect of the ICBGTs; this, however, was attenuated at follow-up. CONCLUSION The Latarjet and ICBGT procedures for the treatment of anterior shoulder instability with glenoid bone loss showed no difference in clinical and radiologic outcomes except for significantly worse internal rotation capacity in the Latarjet group and frequently noted donor-site sensory disturbances in the ICBGT group.

Abstract
Capsulolabral reconstruction (Bankart repair) is recommended as the first line treatment in young and functionally demanding active patients with anteroinferior shoulder instability, due to the high tendency to recurrent dislocation. This has become established both for arthroscopic and open primary shoulder stabilization with good clinical outcome; nevertheless, recurrence of dislocation is reported in up to 25% of patients. Risk factors for failed surgery are patient (e.g. young age, male gender and contact sports) and surgery (e.g. primarily underestimated glenoid bone loss, Hill-Sachs lesion, non-treatment of bipolar defects or malpositioned anchors) related. In the management of recurrent instability, it is necessary to carry out a thorough clinical investigation in addition to extended diagnostics with X‑ray and computed tomography. A second Bankart repair is only indicated in patients with low demands and without any glenoid bone loss. In the majority of patients, bony augmentation of the glenoid is necessary and realized by coracoid or iliac crest bone block transfer. The Latarjet procedure is biomechanically advantageous due to the additional sling effect of the conjoined tendons and both techniques show good clinical outcomes and a low recurrence rate. Furthermore, engaging Hill-Sachs lesions also require additional treatment. Remplissage of the infraspinatus muscle, iliac crest bone block transfer and partial joint replacement are viable options. A final consensus for treatment of Hill-Sachs lesions has yet to be defined. Dislocation arthropathy is an underestimated complication as a result of frequent recurrent dislocations. After development of dislocation arthropathy, patients reported a painful restriction of range of motion rather than instability. Arthroscopic arthrolysis and comprehensive arthroscopic management (CAM procedure) are possible joint-preserving treatment options.

Abstract
INTRODUCTION Glenoid bone loss in recurrent anterior instability of the shoulder needs to be addressed to restore joint stability. Over the last years, several arthroscopic methods have been described to treat this condition. However, no clinical mid-term results have been presented for arthroscopic iliac crest bone grafting procedures. METHODS We included 32 patients with significant glenoid bone loss and repetitive dislocations of the shoulder who were treated in our shoulder unit with a previously described all-arthroscopic reconstruction technique. All patients filled out a questionnaire evaluating repetitive dislocations, consumption of pain medicine, Constant Score (CS, adapted to age and gender), activities of daily living (ADL), visual analogue scale for pain (VAS) as well as the Western Ontario Shoulder Instability Index (WOSI). Additionally, all complications were recorded. RESULTS After a mean follow-up of 42 months, three traumatic dislocations had been observed. With an ADL of 25 points (95% CI 24-27), a WOSI of 71% (95% CI 65-76) and CS of 87 points (95% CI 82-92), our patients showed good functional results. The VAS result for pain was 2.1 (95% CI 1.5-2.6). No patient reported the regular usage of pain medicine related to the shoulder instability at final follow-up. CONCLUSION The all-arthroscopic glenoid reconstruction using iliac crest grafts shows good functional results with a recurrence rate of 9%. At final follow-up 42 months after surgery, our patients showed low pain levels and acceptable complications.

Abstract
Recurrent shoulder instability is highly associated with glenoid bone loss. Traditionally, bony procedures to address this bone loss have described nonanatomic, coracoid transfer procedures. More recently, anatomic glenoid reconstruction procedures have been described. These were first described as open procedures, and subsequently there have been several arthroscopic procedures described. We provide a description of an arthroscopic anatomic glenoid reconstruction approach with allograft.

Abstract
The Latarjet operation is one of the most successful techniques for the treatment of recurrent anterior shoulder instability, which has recently been translated into the arthroscopic field. Several studies suggest that its arthroscopic variant is safe and reproducible and report promising short-term and mid-term results. Some authors claim that, in addition to less soft tissue damage, positioning of the coracoid graft is more accurate during arthroscopic control. There is currently no evidence of superiority of the arthroscopic or the open technique. As with the open procedure, the arthroscopic Latarjet operation requires a substantial learning curve; therefore the arthroscopic technique should be reserved for experienced arthroscopists treating a large number of shoulder instabilities.

Abstract
Recurrent anterior shoulder instability is associated with glenohumeral bone loss. Glenoid deficiency compromises the concavity-compression mechanism. Medial Hill-Sachs lesions can result in an off-track humeral position. Anterior glenoid reconstruction or augmentation prevents recurrence by addressing the pathomechanics. In Bristow and Latarjet procedures, the coracoid process is harvested for conjoint tendon transfer, capsular reinforcement, and glenoid rim restoration. Complications and the nonanatomic nature of the procedure have spurred research on graft sources. The iliac crest is preferred for autogenous structural grafts. Tricortical, bicortical, and J-bone grafts have shown promising results despite the historical association of Eden-Hybinette procedures with early degenerative joint disease. Allogeneic osteochondral grafts may minimize the risk of arthropathy and donor site morbidity. Tibial plafond and glenoid allografts more closely match the native glenoid geometry and restore the articular chondral environment, compared with conventional grafts. Graft availability, cost, risk of disease transmission, and low chondrocyte viability have slowed the acceptance of osteochondral allografts.

Arthroscopic Versus Open Iliac Crest Bone Grafting in Recurrent Anterior Shoulder Instability With Glenoid Bone Loss: A Computed Tomography-Based Quantitative Assessment. Arthroscopy 2018; 34:352-359.

Abstract
PURPOSE To assess the iliac crest bone graft (ICBG) position in the en-face view and axial plane comparing arthroscopic with open procedures. METHODS A total of 40 consecutive patients with recurrent anterior shoulder instability and glenoid bone loss over 10% treated by 2 independent orthopaedic departments were included. Two independent observers analyzed preoperative and immediate postoperative computed tomography scans of 20 open (group O) and 20 arthroscopic (group A) procedures. Defect and ICBG characteristics of the J-shaped graft in the en-face view and axial plane were manually assessed by multiplanar reconstructed computed tomography scans. Variances in terms of graft positioning were analyzed. RESULTS No significant variances in arthroscopic graft positioning were observed. The graft position in the en-face view was comparable in both groups, with the superior extent of the arthroscopic graft (40° ± 9° [inferior extent, 139° ± 16°]) lying significantly higher than the superior extent in group O (50° ± 13°, P = .005 [inferior extent, 147° ± 21°; P = .178]). The covered glenoid defect size was above 95% (98% ± 1% in group O vs 95% ± 2% in group A, P = .001). The arthroscopic graft in the axial plane showed a significantly steeper impaction angle (34.8° ± 7.8° vs 26.9° ± 9.9°, P = .010), with a significantly increased medial offset compared with group O (6.6 ± 1.7 mm vs 5.4 ± 1.3 mm, P = .024). The mediolateral step formation, however, was not significantly different (2.9 ± 1.1 mm in group A vs 3.2 ± 0.8 mm in group O, P = .289). The interobserver reliability was very good for all measurements (R = 0.969; 95% confidence interval, 0.965-0.972). CONCLUSIONS Positioning of the arthroscopic ICBG in the en-face view and axial plane is comparable to that of the open technique. Good glenoid defect coverage and glenoid concavity reconstruction can be achieved with the arthroscopic technique. The main difference compared with the open procedure is the significantly steeper impaction angle. LEVEL OF EVIDENCE Level III, case-control study.

Abstract
Arthroscopic techniques are an emerging technology to deal with glenoid bone defects in patients with anterior shoulder instability, and improvements are being made to safely minimize the risk of injury to the anterior neurovascular structures including the axillary nerve. Arthroscopic glenoid reconstruction is a technically demanding procedure, but it does have promising short-term outcomes. I truly like the concept of anterior (and also posterior) bone grafting for defects of the glenoid, including the arthroscopic Latarjet. A free bone graft (iliac crest, distal tibia) is part of a logical surgical learning curve progression to treat bone defects from an arthroscopic standpoint. Before performing an arthroscopic Latarjet, I might suggest looking at performing free bone block fixation arthroscopically. But, for now, I still enjoy the success of an open bone grafting procedure and will continue to use open as my primary bone grafting (Latarjet, distal tibia, iliac crest), so as to optimize the position of the graft for successful long-term outcomes. We look forward to seeing more of the authors' work and a longer term follow-up of these patients to clearly delineate the development of osteoarthrosis, recurrent instability, and long-term stability of the bone graft and shoulder joint function.

Abstract
BACKGROUND The anatomic restoration of glenoid morphology with an implant-free J-shaped iliac crest bone graft offers an alternative to currently widely used glenoid reconstruction techniques. No biomechanical data on the J-bone grafting technique are currently available. PURPOSE To evaluate (1) glenohumeral contact patterns, (2) graft fixation under cyclic loading, and (3) the initial stabilizing effect of anatomic glenoid reconstruction with the implant-free J-bone grafting technique. STUDY DESIGN Controlled laboratory study. METHODS Eight fresh-frozen cadaveric shoulders and J-shaped iliac crest bone grafts were used for this study. J-bone grafts were harvested, prepared, and implanted according to a previously described, clinically used technique. Glenohumeral contact patterns were measured using dynamic pressure-sensitive sensors under a compressive load of 440 N with the humerus in (a) 30° of abduction, (b) 30° of abduction and 60° of external rotation, (c) 60° of abduction, and (d) 60° of abduction and 60° of external rotation. Using a custom shoulder-testing system allowing positioning with 6 degrees of freedom, a compressive load of 50 N was applied, and the peak force needed to translate the humeral head 10 mm anteriorly at a rate of 2.0 mm/s was recorded. All tests were performed (1) for the intact glenoid, (2) after the creation of a 30% anterior osseous glenoid defect parallel to the longitudinal axis of the glenoid, and (3) after anatomic glenoid reconstruction with an implant-free J-bone graft. Furthermore, after glenoid reconstruction, each specimen was translated anteriorly for 5 mm at a rate of 4.0 mm/s for a total of 3000 cycles while logging graft protrusion and mediolateral bending motions. Graft micromovements were recorded using 2 high-resolution, linear differential variable reluctance transducer strain gauges placed in line with the long leg of the graft and the mediolateral direction, respectively. RESULTS The creation of a 30% glenoid defect significantly decreased glenohumeral contact areas ( P < .05) but significantly increased contact pressures at all abduction and rotation positions ( P < .05). Glenoid reconstruction restored the contact area and contact pressure back to levels of the native glenohumeral joint in all tested positions. The mean (±SD) force to translate the humeral head anteriorly for 10 mm (60° of abduction: 31.7 ± 12.6 N; 60° of abduction and 60° of external rotation: 28.6 ± 7.6 N) was significantly reduced after the creation of a 30% anterior bone glenoid defect (60° of abduction: 12.2 ± 6.8 N; 60° of abduction and 60° of external rotation: 11.4 ± 5.4 N; P < .001). After glenoid reconstruction with a J-bone graft, the mean peak translational force significantly increased (60° of abduction: 85.0 ± 8.2 N; 60° of abduction and 60° of external rotation: 73.6 ± 4.5 N; P < .001) compared with the defect state and baseline. The mean total graft protrusion under cyclical translation of the humeral head over 3000 cycles was 138.3 ± 169.8 µm, whereas the mean maximal mediolateral graft deflection was 320.1 ± 475.7 µm. CONCLUSION Implant-free anatomic glenoid reconstruction with the J-bone grafting technique restored near-native glenohumeral contact areas and pressures, provided secure initial graft fixation, and demonstrated excellent osseous glenohumeral stability at time zero. CLINICAL RELEVANCE The implant-free J-bone graft is a viable alternative to commonly used glenoid reconstruction techniques, providing excellent graft fixation and glenohumeral stability immediately postoperatively. The normalization of glenohumeral contact patterns after reconstruction could potentially avoid the progression of dislocation arthropathy.

Abstract
PURPOSE The purpose of this cadaveric study was to compare standard and modified coracoid transfer procedures, bicortical and tricortical iliac crest autografts, and tibial plafond and glenoid allografts with respect to glenoid surface curvature restoration. METHODS Computed tomography scans of 8 cadaveric shoulders were acquired in 9 conditions: (1) intact, (2) 25% width defect, (3) classic Latarjet, (4) modified congruent-arc Latarjet, (5) tricortical iliac crest inner table, (6) outer table, (7) bicortical iliac crest, (8) distal tibia, and (9) glenoid allograft. Outcome measures included articular surface area, width, depth, axial and coronal radius of curvature, and subchondral articular step-off, analyzed in bone and soft-tissue window. RESULTS Reconstruction of the articular surface area was optimal with the glenoid allograft (99.4%), classic Latarjet (97.4%), and iliac crest bicortical graft (93.2%). Depth was best restored by the congruent-arc Latarjet (101.0%), tibial (98.9%), and glenoid (95.3%) allografts. Axial curvature was closely matched by the glenoid allograft (97.5%), classic Latarjet (108.7%), and iliac bicortical graft (91.2%). Coronal curvature was most accurately restored by the glenoid allograft (102.6%), the tibial allograft (115.0%), and the classic Latarjet (55.9%). The articular step-off was smallest using the glenoid allograft. CONCLUSIONS Overall, glenoid allografts most accurately restored articular geometry. Alternative grafts provided restoration of some parameters but not others. Classic Latarjet performed well in axial and coronal curvature on average but exhibited large variability. Tibial allograft produced the poorest results in axial curvature, despite excellent coronal curvature reconstruction. The congruent-arc Latarjet did not restore the axial curvature accurately and overcorrected coronal curvature. Graft geometry must be weighed against availability, morbidity, and the role of additional stabilizers. CLINICAL RELEVANCE Accurate graft morphology may help prevent postoperative osteoarthritis. Grafts differ significantly regarding geometric parameters. The findings of this study will help surgeons select the most appropriate graft for glenoid reconstruction.

Abstract
BACKGROUND The J-shaped bone graft procedure is one of the recommended methods to reconstruct significant glenoid rim defects. PURPOSE To evaluate long-term (minimum 10-year) clinical outcomes and show further details of the remodeling effects on the articular cavity of the glenoid after J-shaped bone grafting. STUDY DESIGN Case series; Level of evidence, 4. METHODS A total of 14 patients treated with a J-shaped bone graft procedure were observed clinically. Additionally, bilateral preoperative and postoperative follow-up computed tomography (CT) scans were used for CT-osteoabsorptiometry (OAM) to evaluate the bony remodeling processes. RESULTS The follow-up rate was 93% at a mean follow-up time of 10.7 years (range, 10.08-11.75 years). Patients exhibited a mean Constant score of 92.5 (range, 80-100) on the clinical evaluation. All patients had free range of motion and were pain free without any recurrence of instability. Based on CT-OAM, comparable and almost anatomically reconstructed, bilaterally equal glenoid cavities were found postoperatively. The distribution patterns of glenoid subchondral mineralization were bilaterally equal in 85.7% of the patients. CONCLUSION The surgical treatment of recurrent shoulder instability with a significant bony Bankart lesion using the J-shaped bone graft procedure provided excellent long-term results. This study lends evidence to support the capability of the J-shaped bone graft procedure to restore the normal glenoid shape due to physiological remodeling processes.
