Graft Position, Healing, and Resorption in Anterior Glenohumeral Instability: A Comparison of 4 Glenoid Augmentation Techniques. Orthop J Sports Med 2024; 12:23259671241253163. [PMID: 38840788 PMCID: PMC11151773 DOI: 10.1177/23259671241253163] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/24/2023] [Accepted: 11/16/2023] [Indexed: 06/07/2024] Open
Abstract
Background The success of glenoid augmentation procedures depends on accurate placement and healing of the graft to the glenoid. Different glenoid augmentation techniques have been described, but no comparative studies between them exist. Purpose To assess the bone graft position, healing, and resorption in a group of patients treated with 1 of 4 procedures: arthroscopic anterior bone-block procedure using either (1) fresh-frozen iliac crest allograft or (2) iliac crest autograft, (3) open Latarjet, or (4) arthroscopic Latarjet. Study Design Cohort study; Level of evidence, 3. Methods A total of 40 patients (87.5% men; mean age, 29.5 ± 7.9 years) were included, with 10 patients in each of the procedure groups. The graft position in the axial and sagittal planes was assessed on postoperative computed tomography (CT). Graft healing and resorption were assessed in a second CT scan performed 1 year postoperatively. Qualitative variables were compared between the 4 procedures using the chi-square test, and quantitative variables were compared with the Student t test or Mann-Whitney U test. Results No differences were found between the procedures in the axial or sagittal position. The healing rate was significantly lower in the allograft bone-block group (20%) compared with the autograft bone-block (80%), open Latarjet (90%), and arthroscopic Latarjet (90%) groups (P < .001). Graft resorption developed in 17 of 40 (42.5%) cases overall. Osteolysis occurred in 100% of cases in the allograft bone-block group compared with 50% in the autograft group, 20% in the open Latarjet group, and 0% in the arthroscopic Latarjet group (P < .001). The glenoid surface area on 1-year CT scan was significantly lower in the allograft bone-block group compared with the autograft bone-block, open Latarjet, and arthroscopic Latarjet groups (P < .001). Conclusion Arthroscopic bone-block, open Latarjet, and arthroscopic Latarjet procedures provided accurate bone graft positioning. However, very high rates of osteolysis and nonunion were observed in the iliac crest fresh-frozen allograft bone-block procedure when compared with the other procedures.

Modified Suture Button Latarjet Procedure With Coracoacromial Ligament And Pectoralis Minor Preservation Achieves Good Clinical Outcomes at 2-Year Follow-up: Case Series of Latarjet Technique. Arthroscopy 2024:S0749-8063(24)00343-8. [PMID: 38735417 DOI: 10.1016/j.arthro.2024.04.037] [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: 12/06/2023] [Revised: 03/30/2024] [Accepted: 04/14/2024] [Indexed: 05/14/2024]
Abstract
PURPOSES To evaluate if the modified suture button Latarjet procedure with coracoacromial ligament (CAL) and pectoralis minor (PM) preservation could achieve excellent outcomes at the 2-year follow-up. METHODS During January 2019 to January 2021, data of patients who underwent the modified suture button Latarjet with CAL and PM preservation in our department was collected. The glenoid bone loss of these patients were above 20% or over 10% with high demands for exercise. Partial coracoid osteotomy was based on the results of the preoperative 3-dimensional computed tomography (3D CT) evaluation of the glenoid defect area (GDA) and corresponding coracoid process morphology. The preoperative and postoperative clinical results were assessed. The minimal clinically important difference (MCID) was utilized to compare improvement in clinical outcomes. Graft-glenoid union and remodeling were assessed using postoperative 3D CT, and magnetic resonance imaging (MRI) was performed to confirm the integrity of the CAL and PM postoperatively. RESULTS 35 patients were included in this study; the mean follow-up time was 26.9 ± 1.9 months. No case of recurrent dislocation or sublaxity. Significant improvements were observed in mean visual analog scale (VAS) scores for pain during motion, American Shoulder and Elbow Surgeons (ASES) score, Rowe score, and Walch-Duplay score (P < .001). The percentage of patients achieving at least an MCID improvement in clinical outcomes was: VAS 85.71%; ASES 97.14%; Rowe 100%; Walch-Duplay 97.14%. 33 patients (94.3% of all cases) were able to return to their preoperative sport levels, 34 grafts (97.1%) achieved bone union (1 soft union) in 6.3±2.2 months, and the coracoid grafts restored 97.1±4.0% of the perfect fitting circle (PFC) at the last follow-up. Postoperative CT scan showed that 31 grafts (88.6%) were placed ideally in vertical view. In the axial view, 25 grafts (82.9%) were flushed to the glenoid, whereas 1 and 5 grafts were fixed medially and laterally, respectively. The CAL and PM were visualized postoperatively. No arthropathy was observed in any patient at the last follow-up. CONCLUSIONS The modified suture button Latarjet procedure with CAL and PM preservation obtained good clinical and radiological results without recurrence or complications. A substantial majority of patients (>85%) achieved the MCID for the VAS, ASES, ROWE, and Walch-Duplay scores. Additionally, the malpositioned graft (17.1%) did not cause arthropathy of the joints at 2-year follow-up.

J ISAKOS 2024; 9:135-142. [PMID: 38081387 DOI: 10.1016/j.jisako.2023.12.002] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/11/2023] [Revised: 12/03/2023] [Accepted: 12/06/2023] [Indexed: 01/12/2024]
Abstract
OBJECTIVES Magnetic resonance imaging (MRI) is currently the standard diagnostic tool for rotator cuff tears. However, its two-dimensional (2D) output, displayed on a monitor, can complicate the interpretation of anatomy. Three-dimensional (3D) imaging may offer a solution to this issue. This study aimed to demonstrate the diagnostic and interpretive value of a 3D model in assessing lesion anatomy. The hypothesis was that 3D models, compared to 2D MRI, can enhance the comprehension and knowledge of rotator cuff injuries, improve the application of classifications for total tears, and provide a more precise definition of the size and type of tear. METHODS A prospective single-centre study was conducted. 3D models for rotator cuff tears were created and analysed in conjunction with preoperative MRI for each patient up to 2 months before surgery. The 3D models were based on the preoperative MRI. Collected data included 2D plane measurements by MRI in coronal and sagittal planes, descriptions of 3D lesion geometry (new shapes), 3D measurements in coronal and sagittal planes, arthroscopic classifications of rotator cuff injuries, and arthroscopic measurements in coronal and sagittal planes. RESULTS After examining 25 cases, 3D imaging demonstrated similar arthroscopic values post-bursectomy in the sagittal plane (16.70 mm for 3D and 18.28 mm for post-bursectomy, p-value = 0.189), although these measurements did not align with those of MRI (which underestimated measurements, p-value = 0.010). Both MRI measurement and 3D imaging showed similar measurement accuracy in the coronal plane when compared to arthroscopic measurements taken before and after bursectomy. The creation of 3D objects enabled the analysis of new geometries, including the length, width, and depth of each lesion. These geometries included the rectangle, rectangular trapezoid, scalene trapezoid, irregular pentagon, and irregular hexagon. CONCLUSIONS 3D models can enhance the understanding and knowledge of rotator cuff injuries. They can be a promising tool for diagnosing and interpreting the anatomy of the injury, particularly in the sagittal plane. The new 3D understanding of the pathological process has led to the description of new geometric features not visible in conventional 2D MRI. LEVEL OF EVIDENCE II - Development of diagnostic criteria on consecutive patients (all compared to "gold" standard).

The arthroscopic Latarjet procedure with a posterior guided system and suture-button fixation enables more precise bone block positioning in the axial plane versus anterior screws fixation. Knee Surg Sports Traumatol Arthrosc 2024; 32:750-762.

Abstract
PURPOSE Adequate position of the bone block during arthroscopic Latarjet procedure is critical for an optimal functional outcome. However, this procedure is complex with a long learning curve. Our aim was to compare the bone block position between a dedicated glenoid posterior instrumentation and suture button fixation versus an anterior screw fixation, on a postoperative computed tomography (CT) scan. METHOD Seventy-nine consecutive patients operated on for an anterior shoulder instability were included in this retrospective study. The same surgeon performed arthroscopically the Latarjet procedure either with an anterior drilling and screw fixation (Group A), or with a specific posterior glenoid guide pin, a posterior drilling, and a suture cortical button fixation (Group B). Evaluations were made by two independent observers. The position was evaluated by CT scan in the axial and sagittal planes. Learning curves with operative time, complications and clinical outcomes were assessed at a minimum of 2 years of follow-up. RESULTS Thirty-five patients were included in Group A and 44 in Group B. In Group A, 27 bone blocks were flush (87.1%) and 38 in Group B (92.7%) (p < 0.01). In Group A, 72% of the bone block height was below the equator and 76%, in Group B (ns). The mean operating time was 123 ± 32.5 min in Group A and 95 ± 34.1 min in Group B (p < 0.0001). At the final follow-up, the mean aggregate Rowe score was respectively 94.6 ± 10.4 and 93.1 ± 9.8 points in Groups A and B. The mean aggregate Walch-Duplay score was respectively 94.2 ± 11.6 and 93.4 ± 10.6 points in Groups A and B. There were 11 complications (31.4%) in Group A and five complications (11.3%) in Group B (ns). CONCLUSION The arthroscopic Latarjet procedure with a posterior drilling guided system and suture-button fixation allows more precise positioning in the axial plane than with anterior drilling and screw fixation. This posterior-guided procedure could reduce intraoperative and short-term complications. LEVEL OF EVIDENCE Level IV.

Abstract
PURPOSE To investigate the efficacy of all-arthroscopic glenoid bone augmentation surgery using the iliac crest autograft procedure. Furthermore, we sought to compare the clinical and radiographic outcomes of using screw versus button fixation, in patients with recurrent anterior shoulder instability. METHODS Between 2015 and 2019, 134 shoulders with persistent instability were surgically treated with an arthroscopically placed autologous iliac crest bone graft transfer procedure. Preoperative and postoperative clinical follow-up data were evaluated using the range of motion, and the Walch-Duplay, American Shoulder and Elbow Society, and Rowe scores. Radiologic assessment on 3-dimensional computed tomography scans was performed preoperatively, immediately after surgery, as well as postoperatively, at 3 months, 6 months, 1 year, and at the final follow-up stage. Graft positions, healing, and resorption were evaluated from postoperative images. RESULTS This study included 102 patients who underwent arthroscopic iliac crest bone grafting procedure with 2 screws fixation (n = 37; group 1) and 2 button fixation (n = 65; group 2). The mean follow-up period was 37 months. There were no significant differences between groups in terms of clinical scores, shoulder motion range, graft healing, or graft positions on computed tomography scans (P>.05). In group 1, 1 patient showed mechanical irritation and persistent pain around the screw insertion site, being treated through the arthroscopic removal of the screws. The average postoperative bony resorption percentages were 20.3% and 11.2% at 6 months, and 32.4% and 19.3% at 12 months, in group 1 and group 2, respectively. A statistically significant difference was detected between the two groups (P<.05). CONCLUSIONS In the arthroscopic iliac crest bone grafting procedure for the treatment of chronic osseous anterior shoulder instability, excellent functional results were obtained after both button fixation and screw fixation techniques. In addition, less graft resorption and no hardware-related complications were detected with suture button fixation technique. LEVEL OF EVIDENCE Level III, retrospective comparative therapeutic trial.

Abstract
The arthroscopic Bankart-Latarjet procedure is used in the surgical management of anterior shoulder instability. This technique is mainly performed in referral centers due to its high technicity. This study aimed to evaluate surgical outcomes in a peripheral hospital center. This is a retrospective study of patients treated for recurrent anterior shoulder instability. The clinical scores (Walch-Duplay, Rowe, and Western Ontario Shoulder Instability Index (WOSI)) were assessed preoperatively and at 12 months after surgery. The consolidation and the position of the bone block were evaluated at 6 months using a CT scan. Between 2016 and 2020, 40 patients had been operated on (mean age: 28.5 ± 7.9 years). During a mean follow-up of 29.5 ± 11.6 months, we noted only one complication, a case of fracture of the callus of a consolidated bone block. No recurrence of instability was recorded. The Walch-Duplay score increased from 17.8 to 94.6, the Rowe score from 24.9 to 96.8, and the WOSI score decreased from 52.1% to 6.9%. The bone block was consolidated in 35 patients (87.5%), and a flush position with the anterior edge of the glenoid was noted for all patients. At one year, 67.0% of the patients practicing sport had returned to sports. The arthroscopic Bankart-Latarjet technique was a reliable procedure in the hands of an experienced shoulder surgeon, even in a peripheral hospital center.

Abstract
PURPOSE To assess the reproducibility of a new 2-dimensional computed tomography (CT) method of assessing graft positioning in arthroscopic bone block procedure. METHODS This is a prospective observational study. Twenty-seven patients, (all men, mean [Standard deviation] age at surgery 30.9 [8.49] years) were included. Vertical graft position was assessed on the sagittal view by measuring the amount of glenoid bone defect covered by the graft. The length of the bone defect and the amount of graft covering the defect were measured. Positioning of the graft on the sagittal plane was classified as accurate if the graft covered at least 90% of the defect. Intraobserver and interobserver reproducibility was analyzed using intraclass correlation coefficients (ICC) and Kappa coefficient with 95% confidence. RESULTS Excellent intraobserver reproducibility was found, with an ICC of 0.94 (CI 95%, 0.86-0.97). Interobserver reproducibility was good, with the ICC value of 0.71, ranging from 0.45 to 0.86 (CI 95%). CONCLUSION This new method of assessing graft positioning in arthroscopic bone block procedures on 2-dimensional computed tomography scans is reliable, with an excellent intraobserver and good interobserver reproducibility.

Abstract
BACKGROUND There is a current lack of knowledge regarding optimal rehabilitation and duration of sling immobilization after an open Latarjet procedure. A shift towards immediate self-rehabilitation protocols in shoulder surgery is observed to avoid postoperative stiffness and fasten return to sport. Avoiding sling immobilization could further simplify rehabilitation and provide an even faster return to activities of daily living and enhance patient satisfaction. METHODS This study is a single-center, randomized control trial. Sixty-eight patients will be instructed with the same standardized immediate postoperative self-rehabilitation protocol. Patients will be allocated 1:1 between a sling immobilization group for the first three postoperative weeks and no sling group without postoperative immobilization. The primary endpoint will be functional outcome at 6 months postoperative evaluated by the disease-specific Rowe score. Secondary endpoints will include baseline, 1.5-, 6-, and 12-month single assessment numeric evaluation (SANE) of instability score and visual analog pain scale (VAS). At the 6-month time point, graft bony union and position will be assessed by computed tomography. Motion capture technology will evaluate the baseline and 6-month postoperative range of motion. Finally, time to return to work and sport during the first postoperative year, along with patient satisfaction at one postoperative year, will also be recorded. DISCUSSION This study will allow further insights into the optimal rehabilitation protocol after open Latarjet surgery and enhance patient care by helping identify rehabilitation and coracoid graft-related factors influencing functional outcomes, bony union, range of motion, and patient satisfaction. TRIAL REGISTRATION The protocol was approved by the ethical committee board (CCER 2019-02,469) in April 2020 and by ClinicalTrials.gov (Identifier: NCT04479397 ) in July 2020.

Dois médicos radiologistas analisaram as imagens tomográficas pós-operatórias, adquiridas em um banco de dados, para avaliação do posicionamento dos parafusos e das complicações radiográficas.
Resultados Foram avaliados 34 pacientes, com idades entre 21 e 60 anos, sendo que um deles tinha acometimento bilateral dos ombros, totalizando 35 ombros avaliados. A avaliação tomográfica dos ângulos de inclinação dos parafusos não apresentou diferença entre os observadores. Houve concordância intra e interobservador para avaliação dos seguintes parâmetros cirúrgicos: posição do enxerto, presença ou não de complicações radiográficas.
Conclusão A técnica descrita para mensuração do paralelismo dos parafusos na cirurgia de Latarjet apresentou uma concordância intra e inter observador muito boa e excelente, respectivamente. O paralelismo do parafuso com a glenoide é recomendado; no entanto, não é condição obrigatória e única para se evitar as complicações radiográficas.

Abstract
BACKGROUND The prevalence of nonunion after the Latarjet procedure remains high. The purpose of the present study was to investigate healing and clinical outcomes after a novel arthroscopic coracoid process transfer procedure. METHODS Sixty-three patients who underwent the arthroscopic inlay Bristow procedure combined with Bankart repair were identified, and 51 patients who met the inclusion criteria were enrolled in this study. The key feature of this technique was that the coracoid process was trimmed and fixed into a trough (5 to 10 mm deep) in the glenoid neck with a metal screw. Bone graft union and positioning accuracy were assessed with use of postoperative computed tomography (CT) imaging. Clinical examinations, return to sport, and functional scores (American Shoulder and Elbow Surgeons [ASES] and Rowe scores) were recorded. RESULTS The mean duration of follow-up (and standard deviation) was 41.5 ± 7.7 months (range, 36 to 48 months). Postoperative CT scans showed that the position of coracoid graft was at 4:10 (from 3:50 to 5:00) (referencing the right shoulder) in the sagittal view. The α angle was 16.4° ± 9.5°, with 4 (7.8%) of 51 screws being over-angulated (α > 25°). On the axial view, the graft position was considered to be flush in 33 patients (64.7%), medial in 11 (21.6%), congruent in 7 (13.7%), and lateral or too medial in none. At 1 year, the coracoid graft had healed in 49 patients (96.1%) and had failed to unite in 2 patients. CT scanning, performed for 47 patients, showed grade-0 osteolysis in 9 patients, grade-1 osteolysis in 21 patients, and grade-2 osteolysis in 17 patients. At the time of the latest follow-up, there was a significant increase in the Rowe score (from 35.5 ± 8.3 to 95.7 ± 7.2) and the ASES score (from 71.2 ± 9.7 to 91.5 ± 4.4), and 87.0% of patients were able to return to sport. No arthropathy was observed in any patient. CONCLUSIONS After a minimum 3-year follow-up, the arthroscopic inlay Bristow procedure resulted in a high rate of graft healing, excellent clinical outcomes, and a high rate of return to sports.

Abstract
BACKGROUND Since the description of the arthroscopic Latarjet technique, discussion about the superiority of the open or arthroscopic procedure has arisen. The appropriate placement of the coracoid graft (CG) on the anterior glenoid neck is reported to be the most important step of the Latarjet procedure. PURPOSE To verify if there are differences in the parameters that may affect the final position and fixation of CG obtained from the open and arthroscopic Latarjet techniques. STUDY DESIGN Controlled laboratory study. METHODS Twenty fresh-frozen human paired cadaveric shoulder specimens were randomly distributed in 2 surgery groups (open group [OG] and arthroscopic group [AG]) with 10 specimens in each. Two surgeons, each with experience performing open and arthroscopic Latarjet techniques, executed these procedures: one surgeon performed all open techniques, and the other performed all arthroscopic techniques, respectively. After surgery, a computerized tomography scan was performed. The surgical time, the position of each CG, a series of variables that might affect the CG fixation, and the level of the subscapularis muscle split were evaluated. RESULTS The mean surgical time was significantly longer in the AG (mean, 26 minutes for OG and 57 minutes for AG). Three intraoperative complications (30%) were identified in the AG, consisting of graft fractures. The CG was determined to be in an optimal cranial-caudal position in 90% of specimens of the OG and 44% of the AG (Fisher, P = .057). In both groups, the CG was placed in an optimal medial-lateral position in all specimens. In the OG, the degree of parallelism between the major axes of the glenoid surface and CG was significantly greater than in the AG (mean, 3.8º for OG and 15.1º for AG). No significant differences were observed in superior and inferior screw orientation between the groups. In the longitudinal and transverse directions, significant differences were found in the centering of the superior screw, being closer to the ideal point in the OG than in the AG. The location where the longitudinal subscapularis muscle split was performed was significantly higher in the AG. CONCLUSION The open Latarjet technique required less surgical time; presented a lower number of intraoperative complications; and allowed more adequate placement of the CG, better centering of the screws, and a subscapularis muscle split closer to the ideal position. CLINICAL RELEVANCE The reported benefits of the arthroscopic Latarjet technique seem less clear if we take into account the added surgery time and complications.

Abstract
PURPOSE The purpose of this study was to compare the clinical, functional, and radiographic outcomes of open versus arthroscopic Latarjet procedures. METHODS Between December 2009 to January 2015, all patients older than 18 years of age who were treated with a Latarjet procedure for chronic osseous anterior instability by a single surgeon were included in this retrospective cohort study. Range of motion, strength, Rowe, Western Ontario Shoulder Instability Index (WOSI) scores, and pain level according to the Visual Analog Scale (VAS) were evaluated. In addition, postoperative computed tomography scans were used to evaluate the position of the transferred coracoid, screw orientation, and degree of graft resorption. RESULTS Forty-eight patients with a mean age of 29.5 years (range 19-59 years) who underwent open (n = 15; group OL) and arthroscopic (n = 33; group AL) Latarjet procedures were included in the study. The mean follow-up was 30.5 months (range 24-50 months). At final follow-up there were significant differences in the mean internal rotation loss (mean of 9° vs 14°, P = .044) favoring open surgery and WOSI (P = .017) scores favoring arthroscopic. No significant differences were detected in mean forward flexion loss (P = .918), external rotation loss (P = .883), Rowe (P = .429), and Visual Analog Scale (P = .208) scores. Mean superoinferior position of the coracoid bone graft was found between the 1:55 and 4:49 o'clock positions (2:05-4:55 for group OL; 1:51-4:47 for group AL) in en-face views. The grafts were placed laterally in 13% (group OL) and 9% (group AL) of patients. The mean α angles of the screws were 11° and 19.2°, respectively (P = .004). The mean graft resorption rates were 21% and 34% (P = .087), respectively. CONCLUSION Good functional results were obtained after both open and arthroscopic Latarjet procedures for the treatment of chronic osseous anterior shoulder instability. Comparative analysis showed small but statistically significant differences in internal rotation loss favoring open and in WOSI favoring arthroscopic techniques. All measured radiographic parameters were similar with the exception of a significant difference in alpha angle with improved screw position in open surgery. OL and AL techniques provide similar clinical and radiographic outcomes. LEVEL OF EVIDENCE III; Retrospective cohort study with comparison group.

Abstract
BACKGROUND The open Latarjet procedure is a standard surgical treatment option for anterior shoulder instability in patients with a high risk of failure following soft tissue stabilization. The arthroscopic technique has potential advantages of minimal invasiveness, reduced postoperative stiffness, and faster rehabilitation but is regarded as technically challenging with concern over surgical risk during the learning curve. The aim of this study was to undertake a multisurgeon, large-volume learning curve analysis of the arthroscopic Latarjet procedure using continuous learning curve analysis. METHODS Individual patient data from 12 surgeons across 5 countries were retrospectively reviewed. A total of 573 patients undergoing the arthroscopic Latarjet procedure were included. Outcome measures of learning were collected, including operative time, computed tomography (CT) bone-block positioning, complications, and patient-reported outcome measures (PROMs). A segmented linear regression modeling technique was used for learning curve analysis. RESULTS High-volume surgeons converged to an operative time steady state after 30-50 cases. Surgeons completing fewer procedures demonstrated a constant reduction in operative time without reaching a plateau. Low-volume surgeons completing fewer than 14 operations did not demonstrate a reduction in operative time. Accuracy of bone-block positioning on postoperative CT demonstrated constant improvement without reaching a plateau after 53 cases. There was no change in PROMs or complications with increased operative volume. CONCLUSION Specialist shoulder surgeons require 30-50 arthroscopic Latarjet procedures to attain steady-state operative efficiency, during which there is improvement in bone-block positioning. Only surgeons expecting to undertake the arthroscopic Latarjet in high volume should consider adopting this procedure.

Abstract
OBJECTIVE A major factor that impacts the long-term outcome and complication rates of total shoulder arthroplasty is the preoperative posterior glenoid bone loss quantified by glenoid retroversion. The purpose of this study was to assess if glenoid retroversion varies significantly at different glenoid heights in Walch B2 and B3 glenoids. MATERIALS AND METHODS Patients with B2 and B3 glenoid types were included following retrospective review of 386 consecutive CT shoulder studies performed for arthroplasty preoperative planning. True axial CT reconstructions were created using a validated technique. Two readers independently measured the glenoid retroversion angles according to the Friedman method using the "intermediate" glenoid at three glenoid heights: 75% (upper), 50% (equator), and 25% (lower). The variances between the three levels for a given patient were calculated. RESULTS Twenty-nine B2 and 8 B3 glenoid types were included. There was no significant difference in variance of glenoid version among the three levels in B2 or B3 groups. The mean variance in retroversion degree between equator-lower, upper-equator, and upper-lower glenoid was - 0.4, 0.3, and - 0.2 for B2; and - 0.2, 1.9, and 1.9 for B3 glenoid, respectively. The level of inter-reader agreement was fair to good for variance at equator-lower, and good to excellent for upper-equator and upper-lower glenoid. CONCLUSIONS Glenoid version can be accurately measured at any level between 25 and 75% of glenoid height for Walch B2 and B3. We recommend that the glenoid equator be used as the reference to assure consistent and reliable version measurements in this group of patients.

Abstract
PURPOSE To evaluate mid-term clinical outcomes, complications, bone-block healing, and positioning using suture-button fixation for an arthroscopic Latarjet procedure. METHODS Patients with traumatic recurrent anterior instability and glenoid bone loss underwent guided arthroscopic Latarjet with suture-button fixation. We included patients with anterior shoulder instability, glenoid bone loss >20%, and radiographic and clinical follow-up minimum of 24 months. Patients with glenoid bone loss <20% or those that refused computed tomography imaging were excluded. Bone-block fixation was accomplished with 2 cortical buttons connected with a looped suture (4 strands). The looped suture was tied posteriorly with a sliding-locking knot. After transfer of the bone block on the anterior neck of the scapula, compression (100 N) was obtained with the help of a tensioning device. Clinical assessment was performed at 2 weeks, 3 months, 6 months, and then yearly with computed tomography completed at 2 weeks and 6 months to confirm bony union. RESULTS A consecutive series of 136 patients underwent arthroscopic Latarjet with 121 patients (89%; mean age 27 years) available at final follow-up (mean follow-up, 26 months; range, 24-47 months). No neurologic complications or hardware failures were observed; no patients had secondary surgery for implant removal. The transferred coracoid process healed to the scapular neck in 95% of the cases (115/121). The bone block did not heal in 4 patients; it was fractured in 1 and lysed in another. Smoking was a risk factor associated with nonunion (P < .001). The coracoid graft was positioned flush to the glenoid face in 95% (115/121) and below the equator in 92.5% (112/121). At final follow-up, 93% had returned to sports, whereas 4 patients (3%) had a recurrence of shoulder instability. The subjective shoulder value for sports was 94 ± 3.7%. Mean Rowe and Walch-Duplay scores were 90 (range, 40-100) and 91 (range, 55-100), respectively. CONCLUSIONS Suture-button fixation is an alternative to screw fixation for the Latarjet procedure, obtaining predictable healing with excellent graft positioning, and avoiding hardware-related complications. There was no need for hardware removal after suture-button fixation. The systematic identification of the axillary and musculocutaneous nerves reduced risk of neurologic injury. A low instability recurrence rate and excellent return to pre-injury activity level was found. Suture-button fixation is simple, safe, and may be used for both open and arthroscopic Latarjet procedure. LEVEL OF EVIDENCE Level IV, therapeutic case series.

Abstract
BACKGROUND The goal of the Latarjet procedure is restoration of shoulder stability enabled by accurate graft positioning and union. This study aimed to establish a reproducible method of quantitatively assessing coracoid graft osseous union percentage (OUP) using computed tomography (CT) scans and to determine the effect of other factors on the OUP. MATERIALS AND METHODS Postoperative CT scans of 41 consecutive patients treated with the open Latarjet procedure (37% primary, 63% revision) for anterior glenohumeral instability were analyzed for the OUP, position of the graft, and screw type and angle. Two musculoskeletal radiologists independently examined the images 2 times, and intraobserver and interobserver reliability was calculated using intraclass correlation coefficient (ICC). RESULTS Mean OUP was 66% (range, 0%-94%) using quantitate methods, with good intraobserver reliability (ICC = 0.795) and interobserver reliability (ICC = 0.797). Nonunion and significant graft resorption was found in 2 patients. No significant difference was found in the mean OUP in the primary (63%) vs. revision Latarjet procedure (67%). Grafts were flush in 39%, medial in 36%, and lateral in 8%. The medial and neutral graft position was associated with slightly higher OUP (72% and 69%) compared with lateral (65%). OUP was higher when the superior screw angle was less than 17° and the inferior screw angle was less than 24°. This difference did not reach statistical significance. Screw type was not associated with significant difference in OUP. CONCLUSION Quantitative assessment of osseous union of the graft using a reproducible method that we introduced showed similar OUP in the primary and revision Latarjet procedure.

Arthroscopic Latarjet Techniques: Graft and Fixation Positioning Assessed With 2-Dimensional Computed Tomography Is Not Equivalent With Standard Open Technique. Arthroscopy 2018; 34:2032-2040.

Abstract
PURPOSE To analyze graft and fixation (screw and EndoButton) positioning after the arthroscopic Latarjet technique with 2-dimensional computed tomography (CT) and to compare it with the open technique. METHODS We performed a retrospective multicenter study (March 2013 to June 2014). The inclusion criteria included patients with recurrent anterior instability treated with the Latarjet procedure. The exclusion criterion was the absence of a postoperative CT scan. The positions of the hardware, the positions of the grafts in the axial and sagittal planes, and the dispersion of values (variability) were compared. RESULTS The study included 208 patients (79 treated with open technique, 87 treated with arthroscopic Latarjet technique with screw fixation [arthro-screw], and 42 treated with arthroscopic Latarjet technique with EndoButton fixation [arthro-EndoButton]). The angulation of the screws was different in the open group versus the arthro-screw group (superior, 10.3° ± 0.7° vs 16.9° ± 1.0° [P < .001]; inferior, 10.3° ± 0.8° vs 15.7° ± 0.9° [P < .0001]). The angulation of the EndoButtons was 5.7° ± 0.5°; this was different from that of open inferior screws (P = .003). In the axial plane (level of equator), the arthroscopic techniques resulted in lateral positions (arthro-screw, 1.5 ± 0.3 mm lateral [P < .001]; arthro-EndoButton, 0 ± 0.3 mm lateral [P < .0001]) versus the open technique (0.9 ± 0.2 mm medial). At the level of 25% of the glenoid height, the arthroscopic techniques resulted in lateral positions (arthro-screw, 0.3 ± 0.3 mm lateral [P < .001]); (arthro-EndoButton, 0.7 ± 0.3 mm lateral [P < .0001]) versus the open technique (1.0 ± 0.2 mm medial). Higher variability was observed in the arthro-screw group. In the sagittal plane, the arthro-screw technique resulted in higher positions (55% ± 3% of graft below equator) and the arthro-EndoButton technique resulted in lower positions (82% ± 3%, P < .0001) versus the open technique (71% ± 2%). Variability was not different. CONCLUSIONS This study shows that the position of the fixation devices and position of the bone graft with the arthroscopic techniques are statistically significantly different from those with the open technique with 2-dimensional CT assessment. In the sagittal plane, the arthro-screw technique provides the highest positions, and the arthro-EndoButton technique, the lowest. Overall, the mean position of the bone block with the open Latarjet technique in the axial plane is slightly medial to the joint line, as recommended. Conversely, with the arthroscopic techniques, the bone grafts are more lateral with a slight overhang. The main differences are observed in the dispersion of the values (more extreme positions) with the arthro-screw technique, given the acknowledged limitations. Despite the statistical significance, the clinical significance of these differences is yet unknown. LEVEL OF EVIDENCE Level III, retrospective comparative study.

Abstract
BACKGROUND The arthroscopic Latarjet with double-button fixation is a guided procedure recently proposed to treat anterior shoulder instability with glenoid bone loss. The goal of this study was to report intraoperative and early postoperative complications and to analyze the learning curve. METHODS This was a prospective, nonrandomized study that included 88 patients. Intraoperative or postoperative complications as well as adverse events and operative time were recorded. Clinical outcomes were evaluated at 2 weeks, 1.5 months, and at the last follow-up. Radiologic analysis was based on an immediate postoperative computed tomography scan. RESULTS The intraoperative complications or adverse events rate was 3.3%: 1 conversion to open surgery, 1 bone block fracture, and 1 instrumentation problem. The postoperative complication rate was 6.8%: 4 coracoid migrations, and 2 subluxations. None of these complications occurred beyond the 10th case performed. The average operative time significantly decreased with surgical experience (r = -0.8426; 95% confidence interval, -0.9074 to -0.7384; P < .0001) to reach 76 ± 12 minutes (range, 62-95 minutes) at 30 cases. Radiologically, 90% of the bone blocks were flush and subequatorial beyond the 30th case. At a mean follow-up of 12.6 months (range, 6-24 months), Walch-Duplay and Rowe scores were 80 and 81 points, respectively. CONCLUSIONS At short-term follow-up, the arthroscopic Latarjet procedure with double-button fixation exhibited a low complication rate. Operative time significantly improved with surgical experience and was optimized after 30 cases. Early clinical results confirmed that this procedure can be safe and reliable.

Arthroscopically-assisted Latarjet: an easy and reproducible technique for improving the accuracy of graft and screw placement. Shoulder Elbow 2018; 10:99-106.

Abstract
BACKGROUND The effectiveness of the Latarjet largely depends on accurate graft placement, as well as on proper position and direction of the screws. We present our technique for an arthroscopically-assisted Latarjet comparing radiological results with the open technique. METHODS We retrospectively reviewed the postoperative computed tomography scans of 38 patients who underwent a Latarjet procedure. For 16 patients, the procedure was performed with the open technique and, for 22 patients, it was performed using an arthroscopically-assisted technique. An independent radiologist evaluated graft and hardware position, as well as graft integration or resorption. Postoperative complications were also documented. RESULTS The graft was correctly placed in only 18.8% of cases in the open group and 72.7% of cases in the arthroscopically-assisted group. There were no postoperative complications in the arthroscopically-assisted group, whereas one patient had a recurrence and two required hardware removal in the open group. CONCLUSIONS The Latarjet procedure is a challenging procedure for which a key point is the correct placement of the coracoid graft onto the glenoid neck and correct position of the screws. The present study substantiates a clear benefit for the use of a guide with an arthroscopically-assisted technique in terms of graft and hardware placement. At short-term follow-up, there appears to be a benefit for graft integration and avoidance of resorption.

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. [PMID: 29100764 DOI: 10.1016/j.arthro.2017.07.034] [Citation(s) in RCA: 29] [Impact Index Per Article: 4.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/16/2017] [Revised: 07/11/2017] [Accepted: 07/28/2017] [Indexed: 02/02/2023]
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
PURPOSE The Latarjet procedure has shown its efficiency for the treatment of anterior shoulder dislocation. The success of this technique depends on the correct positioning and fusion of the bone block. The length of the screws that fix the bone block can be a problem. They can increase the risk of non-union if too short or be the cause of nerve lesion or soft tissue discomfort if too long. Suprascapular nerve injuries have been reported during shoulder stabilisation surgery up to 6 % of the case. Bone block non-union depending on the series is found around 20 % of the cases. The purpose of this study was to evaluate the efficiency of this CT preoperative planning to predict optimal screws length. The clinical importance of this study lies in the observation that it is the first study to evaluate the efficiency of CT planning to predict screw length. METHODS Inclusion criteria were patients with chronic anterior instability of the shoulder with an ISIS superior to 4. Exclusion criteria were patients with multidirectional instability or any previous surgery on this shoulder. Thirty patients were included prospectively, 11 of them went threw a CT planning, before their arthroscopic Latarjet. Optimal length of both screws was calculated, adding the size of the coracoid at 5 and 15 mm from the tip to the glenoid. Thirty-two-mm screws were used for patients without planning. On a post-operative CT scan with 3D reconstruction, the distance between the screw tip and the posterior cortex was measured. A one-sample Wilcoxon test was used to compare the distance from the tip of the screw to an acceptable positioning of ±2 mm from the posterior cortex. RESULTS In the group without planning, screw 1 tended to differ from the acceptable positioning: mean 3.44 mm ± 3.13, med 2.9 mm, q1; q3 [0.6; 4.75] p = 0.1118, and screw 2 differed significantly from the acceptable position: mean 4.83 mm ± 4.11, med 3.7 mm, q1; q3 [1.7; 5.45] p = 0.0045. In the group with planning, position of screw 1 or 2 showed no significant difference from the acceptable position: mean 2.45 mm ± 2.07 med 1.8 mm, q1; q3 [1; 3.3] p = 1; mean 2.75 mm ± 2.32 med 2.3 mm, q1; q3 [1.25; 3.8] p = 0.5631. CONCLUSION Unplanned Latarjet can lead to inaccurate screw length especially in the lower screw and can increase the risk of non-union and nerve damage. The clinical relevance of this article is that CT planning of screw length before surgery showed good results on post-operative CT.

Abstract
BACKGROUND Bone-grafting procedures for recurrent shoulder instability produce low recurrence rates, although they are associated with complications such as graft non-union. Inadequate screw purchase is considered to play a causative role. However, excessive screw length can endanger neurovascular structures. The present study aimed to investigate how type and length of screws influences construct rigidity in a simplified glenoid model. METHODS Testing was performed on composite polyurethane foam models with material properties and abstract dimensions of a deficient glenoid and an bone graft. Three screw types (cannulated 3.75 mm and 3.5 mm and solid 4.5 mm) secured the graft in a bicortical-bicortical, bicortical-unicortical and unicortical-unicortical configuration. Biomechanical testing consisted of applying axial loads when measuring graft displacement. RESULTS At 200 N, graft displacement reached 0.74 mm, 0.27 mm and 0.24 mm for the unicortical-unicortical and 0.40 mm, 0.25 mm and 0.24 mm for the unicortical-bicortical configuration of the 3.75 mm, 3.5 mm and 4.5 mm screw types. The 3.75 mm screw incurred significant displacements in the unicortical configurations compared to the bicortical-bicortical method (p < 0.001). CONCLUSIONS The present study demonstrates that common screw types resist physiological shear loads in a bicortical configuration. However, the 3.75 mm screws incurred significant displacements at 200 N in the unicortical configurations. These findings have implications regarding hardware selection for bone-grafting procedures.

Reliability of a CT reconstruction for preoperative surgical planning in the arthroscopic Latarjet procedure. Knee Surg Sports Traumatol Arthrosc 2018; 26:40-47. [PMID: 27734111 DOI: 10.1007/s00167-016-4329-1] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/09/2016] [Accepted: 09/15/2016] [Indexed: 10/20/2022]
Abstract
PURPOSE The arthroscopic Latarjet procedure has provided reliable results in the treatment of anterior shoulder instability. However, this procedure remains technically challenging and is related to several complications. The morphology of the coracoid and the glenoid are inconsistent. Inadequate coracoid and glenoid preparing may lead to mismatching between their surfaces. Inadequate screws lengthening and orientation are a major concern. Too long screws can lead to suprascapular nerve injuries or hardware irritation, whereas too short screws can lead to nonunions, fibrous unions or migration of the bone block. The purpose of the study was to investigate the application of virtual surgical planning and digital technology in preoperative assessment and planning of the Latarjet procedure. METHODS Twelve patients planned for an arthroscopic Latarjet had a CT scan evaluation with multi-two-dimensional reconstruction performed before surgery. Interobserver and intraobserver reliability were evaluated. The shape of the anterior rim of the glenoid and the undersurface of the coracoid were classified. Coracoid height was measured, respectively, at 5 mm (C1) and 10 mm (C2) from the tip of the coracoid process, corresponding to the drilling zone. Measurements of the glenoid width were then taken in the axial view at 25 % (G1) and 50 % (G2) of the glenoid height with various α angles (5°, 10°, 15°, 20°, 25°, 30°) 7 mm from the anterior glenoid rim. Shapes of the undersurface of the coracoid and the anterior rim of the glenoid were noted during the surgical procedure. Post-operative measurements included the α angle. RESULTS Concerning coracoid height measurements, there was an almost perfect to substantial intra- and inter-reliability, with values ranging from ICC = 0.75-0.97. For the shape of the coracoid, concordances were, respectively, perfect (ICC = 1) and almost perfect (0.87 [0.33; 1]) for the intra- and interobserver reliabilities. Concerning the glenoid, concordance was always almost perfect for 50 % height. Concordance was almost perfect for 25 % height 15° and 30° for inter- and intraobserver, for intraobserver at 0° and 25°. All the other values were still showing moderate concordance. Shape of the coracoid analysis reproducibility was perfect for both intra- and interobserver ICC = 1. There was a total agreement (ICC = 1) between the preoperative evaluation of the shape of the glenoid and the coracoid and the intraoperative assessment. CONCLUSION The ideal and accurate preoperative planning of screwing of the coracoid graft in the arthroscopic Latarjet can be achieved in the real surgery assisted by the virtual planning. The clinical importance of this study lies in the observation that this new preoperative planning could offer a simple, effective and reproducible tool for surgeons helping them to prepare in the best possible way a technically challenging procedure usually associated with a high rate of complications.

Abstract
Background The present study investigated individualized coracoid osteotomy for 3D congruent arc glenoid reconstruction and evaluated the clinical outcomes in recurrent anterior shoulder dislocation. Methods From January 2005 to July 2015, 78 patients with glenoid defect underwent coracoid and conjoint tendon transposition. The patients were divided into the individualized group (n = 34) and the non-individualized group (n = 44). All patients had CT data to reconstruct the shoulder model using Mimics software. In the individualized group, the individual coracoid osteotomy and bone fixation position parameters were measured from preoperative planification through simulating a 3D congruent arc glenoid reconstruction model. The non-individualized group underwent classic Bristow-Latarjet (B-L) procedure. The postoperative evaluation parameters included 3D congruent arc index, coracoid bone position, shoulder osteoarthritis index (Samilson-Prieto) and shoulder function score (Rowe, Constant-Murley score). Results The mean follow-up time was 51.0 months (ranging from 24 to 146). The individualized group got 3D congruent arc reconstruction of the glenoid by postoperative CT scanning. Bone position was more precise in the individual group than that in the B-L group. There was a lower incidence of shoulder osteoarthritis (Samilson-Prieto) in the individual group compared with that in the B-L group: 0 vs 13.6% (mild 6/44, P = 0.027), respectively. No significant difference was observed between the individual and B-L groups in rate of re-dislocation: 0 vs 4.5% (2/44, P = 0.315), respectively. The postoperative Rowe and Constant score was significantly improved but was not significantly different between the two groups. Conclusion The individual procedure achieved 3D congruent arc glenoid reconstruction. The clinical effects in patients with medium glenoid defect were good, especially the low incidence of shoulder osteoarthritis in middle-term follow-up.

Abstract
Background One of the factors that can affect the success of the Latarjet procedure is accurate coracoid graft (CG) placement. Hypothesis The use of a guide can improve placement of the CG and screw positioning in the sagittal and axial planes as compared with the classic open ("freehand") technique. Study Design Cohort study; Level of evidence, 2. Methods A total of 49 patients who underwent a Latarjet procedure for the treatment of recurrent anterior shoulder instability were prospectively included; the procedure was performed with the freehand technique in 22 patients (group 1) and with use of a parallel drill guide during screw placement in 27 patients (group 2). All patients underwent a postoperative computed tomography scan with the same established protocol. The scans were used to evaluate and compare the position of the CG in the sagittal and axial planes, the direction of the screws (α angle), and overall contact of the graft with the anterior surface of the glenoid after the 2 surgical techniques. Results The CG was placed >60% below the native glenoid equator in 23 patients (85.2%) in group 2, compared with 14 patients (63.6%) in group 1 (P = .004). In the axial plane, the position of the CG in group 2 patients was more accurate (85.2% and 88.9% flush) at the inferior and middle quartiles of the glenoid surface (P = .012 and .009), respectively. Moreover, with the freehand technique (group 1), the graft was in a more lateral position in the inferior and middle quartiles (P = .012 and .009, respectively). No differences were found between groups 1 and 2 regarding the mean α angle of the superior (9° ± 4.14° vs 11° ± 6.3°, P = .232) and inferior (9.5° ± 6° vs 10° ± 7.5°, P = .629) screws. However, the mean contact angle (angle between the posterior coracoid and the anterior glenoid surface) with the freehand technique (3.8° ± 6.8°) was better than that of the guide (8.55° ± 8°) (P = .05). Conclusion Compared with the classic freehand operative technique, the parallel drill guide can ensure more accurate placement of the CG in the axial and sagittal planes, although with inferior bone contact.

Abstract
BACKGROUND The aim of the study was to develop a computed tomography (CT)-based measurement protocol for coracoid graft (CG) placement in both axial and sagittal planes after a Latarjet procedure and to test its intraobserver and interobserver reliability. METHODS Fifteen postoperative CT scans were included to assess the intraobserver and interobserver reproducibility of a standardized protocol among 3 senior and 3 junior shoulder surgeons. The evaluation sequence included CG positioning, its contact area with the glenoid, and the angle of its screws in the axial plane. The percentage of CG positioned under the glenoid equator was also analyzed in the sagittal plane. The intraobserver and interobserver agreement was measured by the intraclass correlation coefficient (ICC), and the values were interpreted according to the Landis and Koch classification. RESULTS The ICC was substantial to almost perfect for intraobserver agreement and fair to almost perfect for interobserver agreement in measuring the angle of screws in the axial plane. The intraobserver agreement was slight to almost perfect and the interobserver agreement slight to substantial regarding CG positioning in the same plane. The intraobserver agreement and interobserver agreement were both fair to almost perfect concerning the contact area. The ICC was moderate to almost perfect for intraobserver agreement and slight to almost perfect for interobserver agreement in analyzing the percentage of CG under the glenoid equator. CONCLUSION The variability of ICC values observed implies that caution should be taken in interpreting results regarding the CG position on 2-dimensional CT scans. This discrepancy is mainly explained by the difficulty in orienting the glenoid in the sagittal plane before any other parameter is measured.

Abstract
Purpose
The aim of this study was to compare the accuracy of the coracoid bone graft placement with the open Latarjet-Patte and arthroscopic Latarjet (arthro-Latarjet) procedures in the treatment of anterior instability of the shoulder.
Methods
Forty-six patients affected by anterior shoulder instability were divided into two groups. In group A (
n
= 25), patients were operated by arthroscopic Latarjet (arthro-Latarjet) procedure and in group B (
n
= 21), patients were operated by open Latarjet-Patte procedure. Instrumental investigation was based on three-dimensional computed tomography (3D-CT) at a minimum 1-year follow-up. Graft placement and integration, divergence and posterior protrusion of the screws, and glenohumeral osteoarthritis were considered as outcomes. Statistical analysis was performed with chi-square or Fisher's exact test. Significance was set at
p
< 0.05.
Results
Positioning of the coracoid graft proved to be optimal in 76% (19/25) of patients of group A and in 100% (21/21) of patients of group B (Fisher's exact test,
p
= 0.025). Screw placement with respect to the glenoid surface showed a posterior divergence in 44% (11/25) of patients in group A and in 24% (5/21) of patients in group B (
p
= 0.15). Posterior protrusion of screw was observed in 76% (19/25) of patients in group A and 71.4% (15/21) of patients in group B (
p
= 0.73). Graft integration was present in 76% (19/25) of patients in group A and 85.7% (18/21) of patients in group B (Fisher's exact test,
p
= 0.48). Mild signs of glenohumeral osteoarthritis were observed in 12% (3/25) of patients in group A and 28.6% (6/21) of patients in group B (Fisher's exact test,
p
= 0.26).
Conclusion
Patients operated with open Latarjet-Patte procedure showed better results than those of the arthro-Latarjet group in reference to the positioning of the graft on the coronal plane (
p
= 0.025). No significant differences between the groups were observed for graft integration, divergence of the screws, posterior protrusion of the screws, and osteoarthritis.

A Prospective Comparative Study of Arthroscopic Versus Mini-Open Latarjet Procedure With a Minimum 2-Year Follow-up. Arthroscopy 2017; 33:269-277. [PMID: 27617665 DOI: 10.1016/j.arthro.2016.06.046] [Citation(s) in RCA: 40] [Impact Index Per Article: 5.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/31/2016] [Revised: 06/21/2016] [Accepted: 06/23/2016] [Indexed: 02/02/2023]
Abstract
PURPOSE To compare postoperative pain during the first postoperative week and the position of the coracoid bone block at the anterior aspect of the glenoid after the arthroscopic and the mini-open Latarjet procedure. The secondary purpose was to assess functional results and recurrence after at least 2 years of follow-up. METHODS This comparative prospective study included patients who underwent a Latarjet-Bristow procedure for anterior shoulder instability in 2012. The Latarjet procedure was performed by a mini-open approach (G1) in one center and by an arthroscopic approach (G2) in the other. The main evaluation criterion was average shoulder pain during the first postoperative week assessed by the patient on a standard 10-cm visual analog scale (0-10). Secondary criteria were consumption of analgesics during the first week, the position of the coracoid bone block on radiograph and computed tomography scan at the 3-month follow-up and clinical outcomes (Western Ontario Score Index and new surgery) after at least 2 years of follow-up. RESULTS Fifty-eight patients were included, 22 G1 and 36 G2, 13 women and 45 men, mean age 26.9 ± 7.7 years. The mean follow-up was 29.8 ± 4.4 months. There was significantly less pain in the arthroscopic Latarjet group than in the mini-open group during the first postoperative week (2.5 ± 1.4 vs 1.2 ± 1.2, P = .002) with comparable consumption of analgesics (P > .05). The arthroscopic Latarjet procedure resulted in a more lateral coracoid bone block (P = .04) and a better equatorial position than the mini-open technique (P = .02). Three patients underwent revision surgery (1 recurrence [2.8%], 1 block fracture, 1 screw ablation) in the arthroscopic group, none in the mini-open group (P = .54). At the final follow-up, the Western Ontario Score Index score was good in all patients (G1: 78.5 ± 7.5% vs G2: 82.3 ± 7%, P = .03). CONCLUSIONS This prospective comparative study showed that the arthroscopic Latarjet procedure was significantly less painful than the mini-open procedure during the first postoperative week. The clinical outcomes were comparable after at least 2 years of follow-up. LEVEL OF EVIDENCE Level II, prospective comparative study.

Accuracy of Latarjet graft and screw position after using novel drill guide. Eur J Trauma Emerg Surg 2016; 43:645-649. [PMID: 27377370 DOI: 10.1007/s00068-016-0703-4] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/03/2015] [Accepted: 06/24/2016] [Indexed: 10/21/2022]
Abstract
PURPOSE For the success of Latarjet procedure a correct graft positioning is mandatory. Furthermore, the correct screw placement is important to avoid cartilage damage and soft tissue irritation. Due to a cadaveric experimental study, the accuracy of graft and screw positioning utilizing a novel drill guide for a minimal-invasive Latarjet procedure was analyzed. METHODS Five human fresh-frozen shoulder specimens have been treated in accordance with the Congruent-Arc Latarjet technique using the glenoid bone loss set (Arthrex, Naples, FL, USA) with 3.75 mm cannulated screws throughout a 5 cm skin incision without detachment of the scapularis tendon. All procedures were performed by one single, experienced shoulder surgeon. The accuracy of graft and screw positioning was assessed due to a CT scan. RESULTS A noticeable learning curve was noted during the study period as the first surgery took 45 min and the last 33 min. All grafts were correctly positioned with regard to the articular line of the glenoid surface. Impingement with the maximum head circumference was not encountered. The screw positions did not affect the suprascapular nerve. A damage of the graft was not noticed. CONCLUSIONS The authors can recommend the usage of the new drill guide tested in this study. It seems to be beneficial in the Latarjet procedure and may ease correct graft positioning and prevent screw misplacement. Compared to fully arthroscopically performed Latarjet procedures it provides much steeper learning curve and seems technically easier and quicker to handle.

Graft position and fusion rate following arthroscopic Latarjet. Knee Surg Sports Traumatol Arthrosc 2016; 24:507-12. [PMID: 25726159 DOI: 10.1007/s00167-015-3551-6] [Citation(s) in RCA: 52] [Impact Index Per Article: 6.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/07/2014] [Accepted: 02/24/2015] [Indexed: 12/25/2022]
Abstract
PURPOSE The arthroscopic Latarjet procedure is recently becoming an increasingly popular technique. Nevertheless, position and fusion of the autograft had not been well studied yet. The purpose of this study was to assess the positioning of the coracoid graft and the fusion rate on CT scan in the arthroscopic Latarjet procedure. METHODS The study design was a prospective series of 19 consecutive patients who received arthroscopic Latarjet procedure. Radiological assessment on CT scan performed 3 months post-operatively included an analysis of the fusion and the position of the coracoid bone graft using a validated method. 02:30-04:20 was considered an ideal positioning in the sagittal view. In the axial view, the positioning was considered as flush, congruent, medial, too medial, or lateral. RESULTS The median age of patients was 27.6 (±6.9). Mean operative time was of 161 min ±34.8. The fusion rate was of 78 %. Coracoid grafts were positioned 01:52 h (56° ± 14°) to 4:04 h (122° ± 12.5°). In the axial view, 32 % of the grafts positioning were considered as flush, 38 % as congruent, 30 % as medial, and 6 % too medial. No lateral position was noted. Two complications occurred, one graft fracture during screwing requiring opening conversion and an early case of osteolysis in a medial-positioned graft. CONCLUSION The arthroscopic Latarjet procedure is a technically challenging technique that provides satisfactory fusion rate and graft positioning with a low complication rate. The clinical importance of this study lies in the observation that it is the first study to evaluate the position of the coracoid bone graft in arthroscopic Latarjet according to a detailed and validated method.
