Abstract
BACKGROUND Glenoid reconstruction with a bone block for anterior glenoid bone loss (GBL) has shown excellent outcomes. However, fixation techniques that require metal implants are associated with metal-related complications and bone graft resorption. HYPOTHESIS Arthroscopic glenoid reconstruction using a tricortical iliac crest bone graft (ICBG) and metal-free suture tape cerclage fixation can safely and effectively restore the glenoid surface area in patients with recurrent anterior shoulder instability and anterior GBL. STUDY DESIGN Case series; Level of evidence, 4. METHODS Adult patients (≥18 years) of both sexes with recurrent anterior shoulder instability and anterior GBL ≥15% were enrolled. These patients underwent arthroscopic glenoid reconstruction with ICBGs and metal-free suture tape cerclage fixation. The effectiveness and clinical outcomes with this technique were evaluated at 24 months using functional scores. Resorption of the graft articular surface was assessed by computed tomography, with the graft surface divided into 6 square areas aligned in 2 columns. Descriptive analysis was conducted. RESULTS A total of 23 consecutive patients met inclusion criteria (22 male, 1 female; mean age, 30.5 ± 7.9 years). The mean preoperative GBL was 19.7% ± 3.4%, and there were 15 allograft and 8 autograft ICBGs. All patients exhibited graft union at 3 months. The median follow-up was 38.5 months (interquartile range, 24-45 months). The Western Ontario Shoulder Instability Index, Rowe, Constant-Murley, and Subjective Shoulder Value scores improved from preoperatively (35.1%, 24.8, 83.1, and 30.9, respectively) to postoperatively (84.7%, 91.1, 96.0, and 90.9, respectively) (P < .001). No differences in clinical scores were observed between the graft types. One surgical wound infection was reported, and 2 patients (8.7% [95% CI, 2.4%-26.8%]) required a reoperation. The mean overall glenoid surface area increased from 80.3% ± 3.5% to 117.0% ± 8.3% immediately after surgery before subsequently reducing to 98.7% ± 6.2% and 95.0% ± 5.7% at 12 and 24 months, respectively (P < .001). The mean graft resorption rate was 18.1% ± 7.9% in the inner column and 80.3% ± 22.4% in the outer column. Additionally, 3 patients treated with an allograft (20.0% [95% CI, 7.1%-45.2%]), including the 2 with clinical failures, exhibited complete graft resorption at the last follow-up. CONCLUSION Arthroscopic glenoid reconstruction using an ICBG and metal-free suture tape cerclage fixation was safe and effective, yielding excellent clinical outcomes. Resorption of the graft articular surface predominantly affected the nonloaded areas beyond the best-fit circle perimeter.

Abstract
Bone augmentation prior to dental implant placement is a common scenario in the dental implantology field. Among the important intraoral harvesting sites to obtain bone blocks is the ramus/retromolar region that has a high success rate and long-lasting alveolar ridge augmentation. Preserving the bone volume and quality at the donor site is crucial for preventing further complications or to serve as a site for re-harvesting. Healing of the intraoral donor sites has been described in the maxillofacial field. This study aimed to evaluate the spontaneous healing of the mandibular retromolar donor site utilizing computer-assisted quantification 6 and 12 months after bone harvesting. MATERIALS AND METHODS The study was conducted on patients who underwent an alveolar ridge augmentation using an intraoral retromolar bone graft. Three CBCT scans were performed-intraoperative, and at six months and one year after the surgical procedure. By using the Materialise Mimics Innovation Suite software 26.0 features segmentation by thresholding, Hounsfield unit averaging, and superimposition of the tomographies, we could precisely quantify the healing process utilizing spatial and characteristic measures. RESULTS In all cases, the computer-aided quantification showed that six months following surgery, the donor site had recovered up to 64.5% ± 4.24 of its initial volume, and this recovery increased to 89.2% ± 2.6 after one year. Moreover, the Hounsfield unit averaging confirmed dynamic bone quality healing, starting at 690.3 ± 81 HU for the bone block, decreasing to 102 ± 27.8 HU at six months postoperatively, and improving to 453.9 ± 91.4 HU at the donor site after a year. CONCLUSIONS This study demonstrates that there is no need for additional replanting at the donor site following retromolar bone block harvesting, whether autogenous or allograft, since spontaneous healing occurs 12 months following the surgery.

Abstract
This exploratory case series clinically and histologically investigated the performance of allogeneic cancellous freeze-dried bone allograft (FDBA) bone blocks (Maxgraft®) for the lateral augmentation of local alveolar defects in the posterior maxilla as part of two-staged implant therapy. Five patients receiving eight implants 5 months after block augmentation with a follow-up period of up to 3 years were documented and analyzed. Horizontal alveolar dimensions before and 5 months after block augmentation were quantified using CBCT. Radiographic marginal bone level changes were quantified at implant placement, loading, and 1 year post-placement. Graft integration and resorption were histologically qualitatively evaluated from core biopsies retrieved at implant placement. Block augmentations resulted in a pronounced horizontal median bone gain of 7.0 (5.5 to 7.8) mm. Marginal implant bone levels in block-augmented bone remained constant over the 1 year follow-up period. Block grafts appeared histologically well integrated. Histologic analysis also revealed signs of progressive resorption and new bone formation at the lateral aspects of the grafts. The results of this case series support using Maxgraft® cancellous FDBA blocks as suitable materials for the lateral augmentation of local alveolar defects.

Abstract
Chronic traumatic anterior shoulder instability can be defined as recurrent trauma-associated shoulder instability requiring the assessment of three anatomic lesions: a capsuloligamentous and/or labral lesion; anterior glenoid bone loss and a Hill-Sachs lesion. Surgical treatment is generally indicated. It remains controversial how risk factors should be evaluated to decide between a soft-tissue, free bone-block or Latarjet-type procedure. Patient risk factors for recurrence are age; hyperlaxity; competitive, contact and overhead sports. Trauma-related factors are soft tissue lesions and most importantly bone loss with implications for treatment. Different treatment options are discussed and compared for complications, return to sports parameters, short- and long-term outcomes and osteoarthritis. Arthroscopic Bankart and open Latarjet procedures have a serious learning curve. Osteoarthritis is associated with the number of previous dislocations as well as surgical techniques. Latarjet-type procedures have the lowest rate of dislocation recurrence and if performed correctly, do not seem to increase the risk of osteoarthritis.

Abstract
Recurrent posterior glenohumeral instability is an entity that demands a high clinical suspicion and a detailed study for a correct approach and treatment. Its classification must consider its biomechanics, whether it is due to functional muscular imbalance or to structural changes, volition, and intentionality. Due to its varied clinical presentations and different structural alterations, ranging from capsule-labral lesions and bone defects to glenoid dysplasia and retroversion, the different treatment alternatives available have historically had a high incidence of failure. A detailed radiographic assessment, with both CT and MRI, with a precise assessment of glenoid and humeral bone defects and of glenoid morphology, is mandatory. Physiotherapy focused on periscapular muscle reeducation and external rotator strengthening is always the first line of treatment. When conservative treatment fails, surgical treatment must be guided by the structural lesions present, ranging from soft tissue repair to posterior bone block techniques to restore or increase the articular surface. Bone block procedures are indicated in cases of recurrent posterior instability after the failure of conservative treatment or soft tissue techniques, as well as symptomatic demonstrable nonintentional instability, presence of a posterior glenoid defect >10%, increased glenoid retroversion between 10 and 25°, and posterior rim dysplasia. Bone block fixation techniques that avoid screws and metal allow for satisfactory initial clinical results in a safe and reproducible way. An algorithm for the approach and treatment of recurrent posterior glenohumeral instability is presented, as well as the author’s preferred surgical technique for arthroscopic posterior bone block.

Abstract
BACKGROUND Improved techniques and increased surgeon experience have optimized surgical care in patients with recurrent shoulder instability. Several techniques are used for surgical repair of shoulder instability, yet there are limited data on how utilization has changed over the past decade. The aim of this study was to assess trends in the utilization rate and patient demographic characteristics (age and sex) from 2010 to 2019 for 4 shoulder instability procedures: coracoid transfer/Latarjet procedure (LP), anterior bone block (ABB), open Bankart repair (OBR), and arthroscopic Bankart repair (ABR). METHODS We identified >87,000 patients using an all-payer claims database. The utilization rate was defined as the number of cases of a procedure divided by the total number of surgical cases for shoulder instability for any given year. Age was divided into 3 groups: <25 years, 25-35 years, and >35 years. Trends were reported in terms of the compounded annual growth rate (CAGR). RESULTS Although ABR was the most common shoulder instability procedure overall (91% utilization rate), the LP had the greatest increase in utilization from 2010 to 2019 (2.0% to 4.5%; CAGR, +9.8%). In comparison, the utilization of ABB procedures increased by 4.3% annually whereas that of OBR declined by 6.9% annually. The utilization of ABR showed minimal change. Notably, the LP was performed more frequently in younger patients over time. The percentage of patients aged < 25 years who underwent the LP increased from 30% to 41% from 2010 to 2019 (CAGR, +3.4%). There was a trend toward the performance of more LPs in men than in women (+1.2% vs. -3.5%, P < .05), although most cases (68%) were still performed in men. CONCLUSION ABR continues to account for most shoulder instability procedures. The LP had the greatest increase in the utilization rate from 2010 to 2019 and has now surpassed OBR in the utilization rate. ABB procedures are also being more frequently performed but only represent a minority of stabilization cases. During the course of the study period, a greater percentage of patients undergoing shoulder instability procedures were male individuals and were aged < 25 years.

Abstract
BACKGROUND The purpose of this study was to assess the outcomes of a new arthroscopic Trillat technique at a 2-year follow-up. Our current hypothesis was that this technique could be used for the effective treatment of chronic post-traumatic unidirectional anterior shoulder instability, and that the recurrence and complication rates, external rotation, and functional outcomes would be as good as those of the reference technique. METHODS Between April 2012 and August 2016, all patients older than 16 years who underwent the arthroscopic Trillat technique for unidirectional chronic post-traumatic anterior shoulder instability at the Dijon University Hospital (France), after the failure of well-conducted medical and rehabilitation treatment with at least 24 months of follow-up, were included. Criteria for noninclusion were association with posterior and/or inferior instabilities, voluntary instabilities, and glenoid bone loss greater than 20%. Patients attended follow-up with their surgeon before the intervention, in the immediate postoperative period, at 6 weeks, 3 and 6 months, and then by an independent observer for the last evaluation. Patients were then examined clinically with scores such as Constant, Rowe and Walch-Duplay scores, and subjective shoulder value, for shoulder range of motion, and radiographically (anteroposterior and Lamy's lateral x-rays of the operated shoulder). RESULTS Forty-nine patients and 52 shoulders were included, with a mean follow-up of 40 months (range, 24-71 months). The recurrence rate of instability was 3.8% (2 of 52). No conversion to arthrotomy was necessary. No intraoperative complications, postoperative neurological lesions, or sepsis were observed. The mean Constant score was 92.1 (77.5-100) points, Walch-Duplay 82.9 (40-100), Rowe 81.73 (5-100), and subjective shoulder value 86.1 (50-100) at the last follow-up. The arm at side external rotation limitation averaged 8.4° (-25° to 40°) and the external rotation with 90° arm abduction limitation 0.34° (-5° to 15°). Forty-one patients (79%) resumed their sports activity at the same level. Fifty patients (96%) were satisfied to very satisfied. One patient developed nonunion of the coracoid process and subsequently underwent a Latarjet procedure with a good outcome. CONCLUSIONS The arthroscopic Trillat procedure offers good outcomes as a first-line treatment for chronic anterior post-traumatic glenohumeral instability. It should be excluded in cases of glenoid loss greater than 20%.

Abstract
Nowadays, implant dentistry is strongly interconnected to bone augmentation procedures. Lateral ridge augmentation is often an imperative treatment stage for successful, prosthetic-driven implant placement. This study aimed to comparatively analyze the immediate postoperative complications of two horizontal bone grafting procedures: sticky bone and bone shell technique. Records of patients with lateral ridge augmentation were analyzed to identify immediate postoperative complications. The study group included 80 patients divided into 40 control (bone-shell technique - BS) and 40 tests (sticky bone -SB). More patients reported moderate and severe pain in the BS - group (11 patients - 27.5%) than in the SB group (6 patients - 15%). In the BS group, the incidence of severe and moderate trismus, neurosensory disturbances, and important hematoma was higher. There was an increased inflammatory response following the bone shell technique, while the sticky bone technique proved reduced surgical morbidity. There was no difference between the two groups in the risk of dehiscence or infection.

Abstract
Background and Objectives: Preliminary studies emphasize the similar performance of autogenous bone blocks (AUBBs) and allogeneic bone blocks (ALBBs) in pre-implant surgery; however, most of these studies include limited subjects or hold a low level of evidence. The purpose of this review is to test the hypothesis of indifferent implant survival rates (ISRs) in AUBB and ALBB and determine the impact of various material-, surgery- and patient-related confounders and predictors. Materials and Methods: The national library of medicine (MEDLINE), Excerpta Medica database (EMBASE) and Cochrane Central Register of Controlled Trials (CENTRAL) were screened for studies reporting the ISRs of implants placed in AUBB and ALBB with ≥10 participants followed for ≥12 months from January 1995 to November 2021. The review was conducted in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. The risk of bias was assessed via several scoring tools, dependent on the study design. Means of sub-entities were presented as violin plots. Results: An electronic data search resulted in the identification of 9233 articles, of which 100 were included in the quantitative analysis. No significant difference (p = 0.54) was found between the ISR of AUBB (96.23 ± 5.27%; range: 75% to 100%; 2195 subjects, 6861 implants) and that of ALBB (97.66 ± 2.68%; range: 90.1% to 100%; 1202 subjects, 3434 implants). The ISR in AUBB was increased in blocks from intraoral as compared to extraoral donor sites (p = 0.0003), partially edentulous as compared to totally edentulous (p = 0.0002), as well as in patients younger than 45 as compared to those older (p = 0.044), cortical as compared to cortico-cancellous blocks (p = 0.005) and in delayed implantations within three months as compared to immediate implantations (p = 0.018). The ISR of ALBB was significantly increased in processed as compared to fresh-frozen ALBB (p = 0.004), but also in horizontal as compared to vertical augmentations (p = 0.009). Conclusions: The present findings widely emphasize the feasibility of achieving similar ISRs with AUBB and ALBB applied for pre-implant bone grafting. ISRs were negatively affected in sub-entities linked to more extensive augmentation procedures such as bone donor site and dentition status. The inclusion and pooling of literature with a low level of evidence, the absence of randomized controlled clinical trials (RCTs) comparing AUBB and ALBB and the limited count of comparative studies with short follow-ups increases the risk of bias and complicates data interpretation. Consequently, further long-term comparative studies are needed.

Abstract
BACKGROUND Recurrence of anterior instability after arthroscopic Bankart prevents return to sports and remains a surgical challenge. We aim to assess clinical and radiologic outcomes after coracoid bone-block performed either open or under arthroscopy, for the management of failed arthroscopic Bankart PATIENTS AND METHODS: Fifty-nine consecutive patients with anterior instability recurrence after arthroscopic Bankart were revised with a Bristow or Latarjet procedure performed either open (25 cases) or under arthroscopy (34 cases). Patients were reviewed for clinical and radiologic examination at a minimum 2-year follow-up. Glenohumeral bony lesions were evaluated preoperatively with computed tomographic scans. Postoperative bone-block position, union, and postinstability arthritis were also evaluated. RESULTS The mean follow-up was 89 months (24-193). The epidemiologic analysis showed that patients with failed arthroscopic Bankart were young (age <23 years), 58 (98%) were practicing sports, with contact/forced overhead sports (53%), often in competition (53%), had hyperlaxity (71%), and for the most part of them glenohumeral bone loss (88%). Their mean preoperative Instability Severity Index Score was 5.4 ± 2.2 points. After revision with Bristow-Latarjet procedure, 53 patients (91%) returned to sports, 37 (70%) to their previous sports activity, and 17 (46%) to their previous level. No patient suffered recurrent dislocation. Four patients (7%) had recurrent subluxations, all after open procedure; 8 patients (14.5%) had persistent anterior apprehension. A large and deep Hill-Sachs lesion was a risk factor for persistent anterior apprehension (P = .002) and lower level when returned to sports (P = .04). Ninety-two percent of bone-blocks were positioned flush with the glenoid anterior rim, with 84% of bone union. At last follow-up, 5% of patients had severe postinstability osteoarthritis (Samilson 4). CONCLUSION The Bristow-Latarjet, performed either open or under arthroscopy, is an efficient procedure to restore shoulder stability and allow returning to sports in patients with failed arthroscopic Bankart and glenoid bone loss. Patients with a large and deep Hill-Sachs lesion had more persistent anterior apprehension and a lower sports level.

Abstract
INTRODUCTION Glenohumeral instability occurs in active-age patients with high recurrence rates in previously described treatments. The objective of the study was to analyze the functional and radiographic results of the patients that underwent a modified Eden-Hybinette technique. MATERIAL AND METHODS From January 2017 to December 2019, 14 patients with post-traumatic anterior glenohumeral instability with glenoid bone loss higher or equal to 15% with or without Hill-Sachs lesion were included, qe used the modified Eden-Hybinette technique and outcomes were evaluated with WOSI and ROWE scales pre and post-procedure at 6, 12, and 24 months follow-up, a CT scan was performed at 6 weeks to evaluate the integration of the graft. RESULTS Five women (35%) and nine men (65%) with a mean age of 39.1 (± 14) years were included. Ten involved the right shoulder (71.4%) and four the left one (28.5%). The results of WOSI and ROWE scales were statistically significant (p 0.05) in postsurgical evaluations as in all periods analyzed in contrast to a pre-surgical standing point; components of the WOSI test were also viewed separately (Sports, Lifestyle, Emotion, and Physical Symptoms) to assess if any of those separately could've altered or significantly influenced the total score obtained, but we found statistical significance (p 0.05) in all parameters. There was no recurrence or complications until the last follow-up. CONCLUSIONS The modified Eden-Hybinette technique offers good short-term functional results. It is a safe technique. Further studies are necessary to determine the effectiveness and possible long-term results and complications.

Abstract
BACKGROUND Meniscal allograft transplantation (MAT) has become a viable treatment option for patients with symptomatic meniscal deficiency. Some patients experience early surgical meniscal allograft failure attributed to causes that have not yet been sufficiently clarified. PURPOSE To evaluate the prevalence, types, and distribution of arthroscopically confirmed meniscal allograft tears and the associated effect on surgical meniscal allograft survival. STUDY DESIGN Cohort study; Level of evidence, 3. METHODS Patients undergoing MAT with a minimum 2-year follow-up were retrospectively reviewed. Descriptive and surgical data were collected. Type and location of arthroscopically confirmed meniscal allograft tears were recorded and compared between medial and lateral allografts and suture-only and bone block fixation. A survival analysis was conducted to evaluate the effect of meniscal allograft tears on surgical meniscal allograft survival. RESULTS This study included 142 patients (54% male; mean ± SD age, 29.6 ± 10.4 years) with a mean follow-up of 10.3 ± 7.5 years. The prevalence of meniscal allograft tears was 32%, observed at a median of 1.2 years (interquartile range, 2.8 years) after MAT. The posterior horns were most frequently affected, followed by the posterior roots, midbodies, anterior horns, and anterior roots. The most frequently observed tear types were root tears (43%), followed by longitudinal, horizontal, radial, complex, bucket-handle, and meniscocapsular separation tears. A statistically significant association was found between meniscal allograft tear types and fixation techniques (P = .027), with root tears predominant after suture-only as compared with bone block fixation (57% vs 22%). Patients with meniscal allograft root tears were a mean of 5.4 years (95% CI, 1.6-9.2 years; P = .007) younger than were patients without root tears. The 1-year surgical meniscal allograft survival rate was significantly lower for torn versus intact meniscal allografts (75% vs 99%; P < .001). CONCLUSION Meniscal allograft root tears were predominant, associated with younger patient age, and more often observed when using the suture-only fixation technique versus the bone block fixation technique. Torn meniscal allografts were associated with early surgical graft failure when compared with intact meniscal allografts, resulting in a significantly lower 1-year survival rate.

Abstract
THE AIM OF THE STUDY Was to conduct an experimental study of the bearing capacity and determination of the Young's modulus of lyophilized allogeneic bone material. MATERIALS AND METHODS The study used 5 prototypes of lyophilized allogeneic bone blocks, which were alternately subjected to static loading by compressive force. The experimental values of Young's modulus of all bone samples were determined. When applying the Student's probability distribution in statistical processing of experimental data, the average indicators of the forces of destruction of the samples were obtained and Young's modulus was determined. RESULTS AND DISCUSSION As a result of the study, the indices of the maximum loading (6012H) and Young's modulus (147.2±0.228 MPa) of lyophilized allogeneic bone material were obtained. CONCLUSION The obtained Young's modulus of lyophilized allogeneic bone material is of great importance in scientific activity, providing the possibility of further investigation of the properties of lyophilized allogeneic bone tissue to form a preoperative forecast of the behavior of an osteoplastic material and a dental implant installed in it.

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. LEVEL Systematic review, IV.

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
Background The Latarjet and bone block procedures can be secured with screws or cortical buttons. The purpose of this biomechanical study was to compare quadruple buttons vs. double screws for fixation of anterior glenoid bone grafts. Methods Twelve cadaveric scapulae (6 pairs) were denuded, resected, and potted. Pairs were randomized to quadruple-button or double-screw fixation after creation of a 15% anterior glenoid defect. The specimens underwent cyclic uniaxial compressive glenoid loading between 50 and 200 N for 1000 cycles at 1 Hz. Testing was repeated for conjoint tendon loads of 0 N (simulating a bone block procedure), 10 N, and 20 N (simulating a Latarjet procedure). Peak resultant relative coracoid graft displacement was optically tracked at 3 points (superior, central, and inferior) on the edge of the coracoid. Results No significant differences were found between buttons and screws for bone block applications or with 10 N of conjoint tendon loading (P ≥ .095). At 20 N of conjoint tendon loading, however, the screws were significantly more stable than the buttons (P ≤ .023). During the initial 20-N conjoint load application, all 3 points displaced significantly more with the button reconstruction than with the screws (P ≤ .01). Overall, mean displacements did not exceed 1 mm at any position on the coracoid, regardless of testing condition. Conclusions The quadruple-button technique is comparable to screws when the coracoid is used as a bone block or when conjoint tendon loading is minimized. However, at higher conjoint tendon loads, the screws produced a more stable coracoid graft than the buttons.

Abstract
BACKGROUND Many surgeons are concerned about reports of increased complications, worse outcomes, and early failures in patients undergoing anatomic total shoulder arthroplasty after coracoid transfer. The purpose of this study was to evaluate minimum 2-year outcomes following anatomic total shoulder arthroplasty for instability arthropathy with a prior coracoid transfer procedure and compare them with a matched cohort of patients undergoing total shoulder arthroplasty for primary osteoarthritis. METHODS We identified 11 primary anatomic total shoulder arthroplasties performed by a single surgeon for instability arthropathy with a prior coracoid transfer procedure with a minimum of 2 years' follow-up (mean, 58 ± 35 months). A matched cohort of 33 patients with a total shoulder arthroplasty for primary osteoarthritis served as the control group. The American Shoulder and Elbow Surgeons (ASES) score, Single Assessment Numeric Evaluation (SANE) score, patient satisfaction, complications, and revisions were evaluated in both cohorts. RESULTS The coracoid transfer cohort showed no difference in the final ASES score (88 vs. 82, P = .166) or SANE score (85 vs. 67, P = .120) vs. the matched cohort. The postoperative ASES pain score (45 vs. 41, P = .004) was higher in the coracoid transfer cohort, but the mean improvement from preoperative to postoperative values for the ASES score (P = .954), ASES pain score (P = .183), and SANE score (P = .293) was no different between cohorts. Both cohorts had high patient satisfaction without a statistically significant difference (P = .784). CONCLUSION At early- to mid-term follow-up, total shoulder arthroplasty performed after a coracoid transfer demonstrated similar results to total shoulder arthroplasty performed for primary osteoarthritis. Longer follow-up and larger patient cohorts will provide further insights and highlight any potential differences in outcomes or revision rates.

Abstract
BACKGROUND Plexiform ameloblastoma is a locally aggressive odontogenic tumor, rare in the anterior mandible. The treatment of choice is resection with 1-3 cm free margins. In most of reported cases, the affected mandible is reconstructed by autogenic bone graft or osseocutaneous microvascular free flap in order to return function and esthetics. CASE DESCRIPTION A 2 cm diameter exophytic ameloblastoma, located in the anterior mandible of a 50-year-old male was resected and reconstructed in a unique manner-allogenic bone block, recombinant human bone morphogenetic protein (rhBMP) and xenograft particles via transcutaneous submental approach. After bone maturation, dental implants were placed and restored by fixed prosthetics. PRACTICAL IMPLICATIONS Mandible reconstruction modalities have a crucial influence on patient quality of life, function and esthetics. Allogenic bone block combined with rhBMP and xenograft particles can replace the traditional autogenous bone in certain circumstances. A submental transcutaneous "tent pole" approach can improve the success rate of the reconstruction procedure.

Abstract
Recurrent glenohumeral dislocation is usually associated with bone loss of the glenoid portion, with the anteroinferior location being the most affected. The understanding of the related structures, as well as the use of current imaging studies such as computed axial tomography and magnetic resonance imaging, have made progress in understanding the pathology, as well as the development of surgical materials and minimally invasive tools, they allow us to continue innovating with respect to the previously described treatments, being possible to intervene in technical details with the intention of improving the results. That is why we have done what described by Eden-Hybinette, using tricortical cadaveric graft and as fixation method, limiting the comorbidities associated with the autograft taking, resulting a wide benefit for the patient, during the surgical procedure and in the recovery period.

Abstract
The present publication reports the purification effort of two natural bone blocks, that is, an allogeneic bone block (maxgraft®, botiss biomaterials GmbH, Zossen, Germany) and a xenogeneic block (SMARTBONE®, IBI S.A., Mezzovico-Vira, Switzerland) in addition to previously published results based on histology. Furthermore, specialized scanning electron microscopy (SEM) and in vitro analyses (XTT, BrdU, LDH) for testing of the cytocompatibility based on ISO 10993-5/-12 have been conducted. The microscopic analyses showed that both bone blocks possess a trabecular structure with a lamellar subarrangement. In the case of the xenogeneic bone block, only minor remnants of collagenous structures were found, while in contrast high amounts of collagen were found associated with the allogeneic bone matrix. Furthermore, only island-like remnants of the polymer coating in case of the xenogeneic bone substitute seemed to be detectable. Finally, no remaining cells or cellular remnants were found in both bone blocks. The in vitro analyses showed that both bone blocks are biocompatible. Altogether, the purification level of both bone blocks seems to be favorable for bone tissue regeneration without the risk for inflammatory responses or graft rejection. Moreover, the analysis of the maxgraft® bone block showed that the underlying purification process allows for preserving not only the calcified bone matrix but also high amounts of the intertrabecular collagen matrix.

Abstract
BACKGROUND Coracoid transfer has become increasingly popular for recurrent anterior shoulder instability. Despite the success, glenohumeral arthropathy develops in some patients. Arthroplasty in this population is complicated by altered anatomy, scarring, and retained hardware. This study evaluated shoulder arthroplasty in patients with a previous Latarjet or Bristow procedure. METHODS Between 1980 and 2014, 33 patients underwent shoulder arthroplasty after coracoid transfer. Of these, 17 men and 13 women were monitored for a minimum of 2 years or until reoperation. Arthroplasty procedures included hemiarthroplasty (HA) in 5, total shoulder arthroplasty (TSA) in 14, and reverse shoulder arthroplasty (RTSA) in 11. Outcome measures included pain, range of motion, complications, and reoperations. RESULTS At the most recent follow-up, pain had significantly improved in all arthroplasty groups. Elevation and external rotation also improved significantly (P < .001). Overall, 9 shoulders (30%) underwent revision for instability (1 TSA and 1 HA), glenoid loosening (1 TSA), instability and glenoid loosening (3 TSA), late cuff failure (1 TSA), and painful glenoid erosion (2 HA). Revision rates were significantly different between HA and RTSA (P = .0058) and between TSA and RTSA (P = .015). Radiographically, 2 additional anatomic glenoid components were considered loose, progressive medial erosion was seen in 1 HA, and grade 1 to 2 notching was observed in 2 RTSAs. CONCLUSIONS Shoulder arthroplasty in patients after prior coracoid transfer is technically challenging, yet improvements in pain and function are predictable. Instability and glenoid loosening are common reasons for revision surgery, likely related to difficulties in achieving a good soft tissue balance.

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.

Abstract
The objective of this case report is to introduce a customized CAD/CAM freeze-dried bone allograft (FDBA) block for its use in Guided Bone Regeneration (GBR) procedures for severely deficient maxillary bones. Additionally, a special newly developed remote incision technique is presented to avoid wound dehiscence. The results show optimal integration behavior of the FDBA block after six months and the formation of new vital bone. Thus, the results of the present case report confirm the use of the customized CAD/CAM bone block for augmentation of complex defects in the maxillary aesthetic zone as a successful treatment concept.

Abstract
Background/purpose The aim of this prospective randomized controlled clinical trial was to compare vertical bone gain and bone resorption after sinus graft procedures performed either with particulate or with autogenous bone block. Material and methods Forty-one patients underwent sinus graft procedures with autogenous bone. They were randomly assigned to one group. The first group of 22 patients was treated with autogenous bone block with or without particulated bone, while in the second group of 19 patients sinus floor elevation was performed only with particulated autogenous bone. Linear measurements were recorded before surgery with a computed tomography scan at surgery and at 36 months after sinus lift grafting with a second computed tomography scan. To detect statistical differences Student t test was applied. Differences were considered significant if P values were < 0.05. Results There was a statistically significant difference in bone gain for the group treated with bone block grafts. Conclusion As a general clinical guideline the clinician should prefer, wherever feasible, en-block bone grafts for sinus floor augmentation procedures.

Abstract
BACKGROUND Our first-line choice of surgical method for massive shoulder rotator cuff tears not amenable to primary repair is a patching method that uses a graft consisting of a section of the iliotibial band with an attached bone block. The objective of this study was to examine the functional and structural results. METHODS The study included 5 patients who were not eligible for primary repair, received iliotibial band autografts with an attached bone block, and could be monitored for 2 years or more. The grafting method involved suturing the ligament part of the graft to the remaining rotator cuff and fixing the bone part to the greater tubercle of the humerus by means of a suture-bridge technique. Clinical evaluation was performed for 24 months postoperatively. Postoperative structural evaluation was performed using computed tomography at 3 to 4 months and magnetic resonance imaging at 6, 12, and 24 months. RESULTS A clear improvement was seen at the final clinical evaluation. Fusion of the bone graft with the greater tubercle of the humerus was confirmed on computed tomography in all patients. No retearing was observed on magnetic resonance imaging at the 24-month point, and the thickness of the ligament part of the graft was maintained. CONCLUSION The patching method using an iliotibial band with an attached bone block as the graft enabled good reconstruction of the rotator cuff, including the greater tubercle footprint. Moreover, good clinical results were seen at 24 months.

Abstract
HYPOTHESIS We hypothesized that the arthroscopic Latarjet procedure could be performed with accurate bone block positioning and screw fixation with a similar rate of complications to the open Latarjet procedure. METHODS In this prospective study, 105 shoulders (104 patients) underwent the arthroscopic Latarjet procedure performed by the same senior surgeon. The day after surgery, an independent surgeon examiner performed a multiplanar bidimensional computed tomography scan analysis. We also evaluated our learning curve by comparing 2 chronologic periods (30 procedures performed in each period), separated by an interval during which 45 procedures were performed. RESULTS Of the 105 shoulders included in the study, 95 (90.5%) (94 patients) were evaluated. The coracoid graft was accurately positioned relative to the equator of the glenoid surface in 87 of 95 shoulders (91.5%). Accurate bone-block positioning on the axial view with "circle" evaluation was obtained for 77 of 95 shoulders (81%). This procedure was performed in a lateralized position in 7 of 95 shoulders (7.3%) and in a medialized position in 11 shoulders (11.6%). The mean screw angulation with the glenoid surface was 21°. One patient had transient axillary nerve palsy. Of the initial 104 patients, 3 (2.8%) underwent revision. The analysis of our results indicated that the screw-glenoid surface angle significantly predicted the accuracy of the bone-block positioning (P = .001). Our learning curve estimates showed that, compared with our initial period, the average surgical time decreased, and the risk of lateralization showed a statistically significant decrease during the last period (P = .006). CONCLUSIONS This study showed that accurate positioning of the bone block onto the anterior aspect of the glenoid is possible, safe, and reproducible with the arthroscopic Latarjet procedure without additional complications compared with open surgery.

Abstract
BACKGROUND The operative management of failed hallux metatarsophalangeal joint surgery can be difficult. There is often substantial shortening of the first ray. Arthrodesis of the first metatarsophalangeal joint is one treatment option, but results in further shortening of the first ray. METHODS We present a large retrospective series of patients who had an interposition bone block arthrodesis procedure performed using a nonvascularized tricortical autologous iliac crest bone graft in an attempt to maintain first ray length. Twenty-four patients (25 feet) underwent this salvage procedure over a 10-year period. The mean follow-up period was 62 (range, 11-117) months. RESULTS Indications included failed hallux valgus surgery, Keller's procedures, various other first metatarsal osteotomies, and failed arthrodesis procedures with shortening of the first ray. All patients had tricortical iliac crest grafts inserted into bony defects of mean length 10.7 (range, 8-15) mm. Fixation was achieved using either multiple wires or a low-profile plate. Mean lengthening was 4.4 (range, 0-8) mm. Three feet went on to nonunion requiring further revision surgery and at latest follow-up 2 had united. All patients underwent removal of a stabilizing Kirschner wire. Median patient-reported outcome score using the Foot and Ankle Disability Index was 84.6 (range, 37.5-97.1). CONCLUSION These results suggest this procedure was successful in salvaging failed first ray surgery and prevented further shortening. We believe good results can be achieved, but care must be taken to ensure wound closure without excessive tension to permit wound healing. LEVEL OF EVIDENCE Level IV, retrospective case series.

Abstract
BACKGROUND Coracoid bone graft osteolysis and fibrous union are the principal causes of failure in patients treated with the Latarjet procedure. This study aims to investigate the hypothesis that coracoid bone graft osteolysis is more pronounced in cases without glenoid bone loss, which may be due to a diminished mechanotransduction effect at the bone healing site. METHODS We prospectively followed up 34 patients, treated with a mini-plate Latarjet procedure, divided into 2 groups (group A patients had glenoid bone loss >15% and group B patients had no glenoid bone loss). A computed tomography scan evaluation with 3-dimensional reconstruction was then performed on all patients to evaluate coracoid bone graft osteolysis according to our coracoid bone graft osteolysis classification. RESULTS The computed tomography scan analysis showed a different distribution of osteolysis between group A and group B. The statistical analysis showed a significant difference (P < .01, Bonferroni test) between groups A and B for the following sections: proximal/lateral/superficial, proximal/medial/deep, distal/lateral/superficial, and distal/lateral/deep. On average, the coracoid grafts in group A patients showed less osteolysis than the coracoid grafts in group B patients (39.6% vs 65.1%). DISCUSSION The coracoid bone graft underwent much less osteolysis in patients with significant glenoid bone loss (>15%) than in those without it. Because factors of blood supply, compression, and surgical technique were the same for both groups, we believe that the mechanotransduction effect from the humeral head on the graft influences its remodeling. CONCLUSION The results of this study suggest that the bone graft part of the Latarjet procedure plays a role in patients with significant coracoid bone loss but much less so when there is no bone loss.

Abstract
BACKGROUND AND AIM To assess the success rate of implants placed in atrophic ridges, regenerated by means of block bone grafts harvested from iliac crest, calvaria or intraoral donor sites (mandibular ramus, chin). METHODS AND MATERIALS A systematic review of all prospective and retrospective studies analyzing the success rate of implants placed simultaneously or as a second surgery following ridge augmentation by means of onlay graft technique, compared with implants placed in pristine bone, was performed. To be included, studies had to involve at least five consecutively treated patients and to report clearly specified success criteria. It was also necessary a minimum follow-up period of six months, to allow the observation of potential biological complications during function, rather than early implant failures. In order to assess the success rate of implants in terms of health of periimplant tissues, implant stability, osteointegration and bone resorption, studies reporting only the survival rate of implants, were excluded. RESULTS From 323 potentially relevant studies, 65 full-text publications were screened and eight were identified as fulfilling the inclusion criteria. The success rate of implants placed in onlay graft regenerated ridges ranged from 72,8% to 97% after follow-up periods ranging from 6 months to 10 years, with all the studies but two, reporting a success rate higher than 84% (range 84-97%). CONCLUSION The obtained data demonstrated that the success rate of implants placed in regenerated areas are very similar to those obtained in case of implants placed in pristine bone, and suggested that onlay graft augmentation is a quite predictable technique to allow the placement of implants in severely atrophic areas. Despite that, the current review revealed that there are not many studies providing data on the success rate of dental implants placed in onlay graft augmented ridges and demonstrated, on average, a poor methodological quality. So randomized controlled studies adopting standardized criteria to define success and failure of implants are required and data from this review must be considered indicative.
