European Society for Surgery of the Shoulder and Elbow (SECEC) rotator cuff tear registry Delphi consensus.

Background: The purpose of this study was to establish consensus statements via a Delphi process on the factors that should be included in a registry for those patients undergoing rotator cuff tear treatment. Methods: A consensus process on the treatment of rotator cuff utilizing a modified Delphi technique was conducted. Fifty-seven surgeons completed these consensus statements and 9 surgeons declined. The participants were members of the European Society for Surgery of the Shoulder and Elbow committees representing 23 European countries. Thirteen questions were generated regarding the diagnosis and follow-up of rotator cuff tears were distributed, with 3 rounds of questionnaires and final voting occurring. Consensus was defined as achieving 80%-89% agreement, whereas strong consensus was defined as 90%-99% agreement, and unanimous consensus was defined by 100% agreement with a proposed statement. Results: Of the 13 total questions and consensus statements on rotator cuff tears, 1 achieved unanimous consensus, 6 achieved strong consensus, 5 achieved consensus, and 1 did not achieve consensus. The statement that reached unanimous consensus was that the factors in the patient history that should be evaluated and recorded in the setting of suspected/known rotator cuff tear are age, gender, comorbidities, smoking, traumatic etiology, prior treatment including physical therapy/injections, pain, sleep disturbance, sports, occupation, workmen's compensation, hand dominance, and functional limitations. The statement that did not achieve consensus was related to the role of ultrasound in the initial diagnosis of patients with rotator cuff tears. Conclusion: Nearly all questions reached consensus among 57 European Society for Surgery of the Shoulder and Elbow members representing 23 different European countries. We encourage surgeons to use this minimum set of variables to establish rotator cuff registries and multicenter studies. By adapting and using compatible variables, data can more easily be compared and eventually merged across countries.

Outcomes of a cementless onlay short stem reverse shoulder arthroplasty in elderly patients: a comprehensive analysis of clinical and radiological findings.

OBJECTIVE: The objective of this study was to evaluate clinical and radiological outcomes of a short stem reverse shoulder prosthesis with metaphyseal fixation specifically in older patients. METHODS: All patients, older than 70 years, submitted to a Reverse Shoulder Arthroplasty (RSA) using a cementless onlay short stem (Aequalis Ascend™ Flex Convertible Shoulder System (Stryker®)) from January 2017 to December 2021, with a minimum follow-up of 2 years, were included. Postoperative radiographs were assessed for stem loosening, subsidence, and varus-valgus tilt. Range of motion, visual analogue scale for pain, constant score, complication rate and revision rate were also analysed. RESULTS: A total of 34 patients with a mean age of 75 years (range 71-83 years) were submitted to a cementless onlay short stem RSA with a Bone Increased Off-Set (BIO-RSA) construct. The mean follow-up period was 61 months (range 54-87). Significant improvements (p < 0.001) were observed for the constant score and range of motion from the preoperative state to final follow-up. One case exhibited a significant varus deviation (> 5˚) during the follow-up period. No case of stem loosening was identified. There was only one case of complication because of post-traumatic dislocation, but the stem didn't need revision. CONCLUSION: Short stem RSA, even in patients older than 70 years, can yield a stable fixation with a good clinical and radiological outcome at short-medium term follow-up. LEVEL OF EVIDENCE: Level III; Retrospective Study.

Greater tuberosity fractures of the humerus: complications and long-term outcomes after surgical treatment.

BACKGROUND: Isolated greater tuberosity (GT) fractures typically occur in younger patients following high-energy trauma compared to humeral neck fractures. Surgical treatment is indicated when superior displacement is > 5 mm. This study aimed to assess the complications and long-term outcomes of surgically-treated GT fractures. METHODS: A retrospective review of 39 patients who underwent surgery from 2010 to 2014 was conducted. The cohort comprised 54.6% females, with an average age of 56.74 years and a median follow-up of 6.71 years. Only 25 patients returned for reevaluation, with functional outcomes assessed using Constant-Murley score. RESULTS: Women were older than men (63.00 ± 12.15 vs. 48.65 ± 16.93, p = 0.006). 18/39 patients (46.1%) sustained avulsion-type, 1 patient out of 39 (2.6%) depression-type, and 20/39 patients (51.3%) split-type fractures. The mean Constant-Murley score was 84.08 ± 18.36, with higher scores observed in men (p = 0.021). Avulsion-type fractures were related to higher postoperative scores compared to split fractures (p = 0.069). Post-surgical complications occurred in 20.5% of patients, with no differences noted between sexes, fracture types, or procedures. CONCLUSION: This study enhances understanding of the long-term outcomes of surgically-treated GT fractures, aiding in treatment selection. Interfragmentary screws may be preferable in younger male patients, but are associated with the higher risk of reintervention, particularly in fragile bone. Prospective multicentric studies are warranted to further elucidate long-term results and treatment strategies.

Comparative analysis of proximal humerus fracture management in elderly patients: complications of open reduction and internal fixation by shoulder surgeons and non-shoulder surgeons-a retrospective study.

BACKGROUND: Open reduction and internal fixation (ORIF) with a locking plate is a popular surgical treatment for proximal humeral fractures (PHF). This study aimed to assess the occurrence of complications in elderly patients with PHF treated surgically using ORIF with a locking plate and to investigate the potential differences between patients treated by shoulder surgeons and non-shoulder surgeons. METHODS: A retrospective study was conducted using a single-center database to identify patients aged ≥70 years who underwent ORIF for PHF between January 1, 2011, and December 31, 2021. Data on the Neer classification, follow-up, occurrence of avascular necrosis of the humeral head, implant failure, and revision surgery were also collected. Statistical analyses were performed to calculate the overall frequency of complications according to the Neer classification. RESULTS: The rates of implant failure, avascular osteonecrosis, and revision surgery were 15.7%, 4.8%, and 15.7%, respectively. Complications were more common in patients with Neer three- and four-part fractures. Although the difference between surgeries performed by shoulder surgeons and non-shoulder surgeons did not reach statistical significance, the rate of complications and the need for revision surgery were nearly two-fold higher in the latter group. CONCLUSIONS: PHF are highly prevalent in the elderly population. However, the ORIF surgical approach, as demonstrated in this study, is associated with a considerable rate of complications. Surgeries performed by non-shoulder surgeons had a higher rate of complications and a more frequent need for revision surgery. Future studies comparing surgical treatments and their respective complication rates are crucial to determine the optimal therapeutic options. Level of evidence: III.

Improved outcomes of older patients with acute and displaced proximal humerus fractures treated with window bone ingrowth fracture-specific stem reverse shoulder arthroplasty.

BACKGROUND: The optimal treatment of displaced proximal humerus fractures (PHFs) in the older people population remains controversial. Reverse shoulder arthroplasty (RSA) is a popular surgical treatment option that provides improved and reproducible results. However, the relevance of fracture-specific stem designs for RSA to improve tuberosity consolidation and shoulder function remains debatable. METHODS: This study included all patients 70 years or older with acute and displaced PHFs primarily treated with RSA at a single institution in Portugal, between January 2010 and December 2019 who participated in a minimum follow-up of 2 years. RESULTS: A total of 112 patients (15 men and 97 women) with a median clinical follow-up of 52 months were included. The mean age at the time of fracture was 78.6 years. All fractures were classified as Neer types 3 and 4 (n = 50 and n = 62, respectively). A window bone ingrowth fracture-specific stem was used for 86 patients, and a conventional humeral stem was used for 26 patients. Regarding the tuberosity fixation technique, 76 tuberosities were attached using technique A (according to Boileau's principles), 36 tuberosities were attached using technique B (not following Boileau's principles) and 11cases were classified as technique C (if fixation was not possible). The overall survival rate during the 2-year follow-up was 88.2%; however, this decreased to 79% at 5 years. Only three patients had complications (two infections and one dislocation) requiring revision surgery. In the multivariable analysis, the tuberosity fixation technique (P = 0.012) and tuberosity anatomical consolidation (P < 0.001) were associated with improved Constant scores (median Constant Score 62.67 (technique A), 55.32 (technique B), 49.70 (technique C). Fracture-specific humeral implants (P = 0.051), the tuberosity fixation technique (P = 0.041), tuberosity anatomical consolidation (P < 0.001), and dementia influenced the achievement of functional mobility (P = 0.014). Tuberosity anatomic consolidation was positively associated with bone ingrowth fracture-specific humeral implants (P < 0.01) and a strong tuberosity fixation technique (P < 0.01). CONCLUSION: RSA is used for complex and displaced fractures of the proximal humerus in older patients. Dementia was negatively correlated with functional outcomes. A window bone ingrowth fracture-specific stem combined with strong tuberosity fixation can yield better clinical and radiological results. LEVEL OF EVIDENCE: Level II; prospective comparative study; treatment study.

Lateralized versus nonlateralized glenospheres in reverse shoulder arthroplasty: a systematic review with meta-analysis.

HYPOTHESIS/BACKGROUND: Lateralization in reverse shoulder arthroplasty (L-RSA) was proposed to overcome some limitations of the original Grammont-style design (S-RSA). This systematic review aims to compare the clinical and functional outcomes and complications of S-RSA with L-RSA, and to assess the individual results of metallic and bony lateralization implants. METHODS: A systematic search from January 1980 to December 2019 was performed. Studies were selected in 2 phases by 2 independent reviewers; disagreements were solved by discussion. Inclusion criteria were: (1) original studies; (2) written in English or French; (3) adult individuals submitted to RSA surgery; and (4) RSA with a lateralization device in at least one of the groups. Exclusion criteria were: (1) nonoriginal studies or case reports; (2) absence of clinical or radiographic outcomes; and (3) no comparison group using S-RSA. Data were extracted for outcomes of functional status (American Shoulder and Elbow Surgeons, Constant, visual analog scale, Simple Shoulder Test, Subjective Shoulder Value, Activities of Daily Life that require External Rotation, and Disabilities of the Arm, Shoulder, and Hand), range of motion (ROM), complications, revisions, and notching. Meta-analyses were performed when possible. Preferred Reporting Items for Systematic Reviews and Meta-Analysis guidelines were followed. RESULTS: Fifteen articles/16 studies were included (865 participants: 440 L-RSA and 425 S-RSA). Most studies found no differences between the L-RSA and S-RSA groups in qualitative and meta-analysis for American Shoulder and Elbow Surgeons, Constant, Simple Shoulder Test, Activities of Daily Life that require External Rotation, and Disabilities of the Arm, Shoulder, and Hand scores. Meta-analysis demonstrated significantly lower visual analog scale (1 point) and higher Subjective Shoulder Value (6 points) in L-RSA than in S-RSA. No significant differences were found in the qualitative analyses of most studies regarding ROM in forward elevation, abduction, and internal/external rotation, but meta-analysis reported a significantly higher external rotation in L-RSA groups and specifically in osseous lateralization. Complication rate was significantly lower in L-RSA (odds ratio = 0.38), but no significant differences were found for revision rates. Notching rate was significantly lower in the L-RSA group (odds ratio = 0.14), both for osseous and metallic lateralization. DISCUSSION/CONCLUSION: This systematic review focused on studies comparing L-RSA and S-RSA and found significantly lower notching and complication rates in L-RSA groups. This review highlighted similar outcomes in clinical scores and a slight advantage for L-RSA in ROM, especially in external rotation. L-RSA was not associated with increased revision rates, while presenting lower complication and notching rates. Inclusion of studies with metallic and osseous lateralization has helped to provide further evidence on this subject, but heterogeneity and low evidence levels of the included studies may limit our conclusions.

Tuberosity Healing after Reverse Shoulder Arthroplasty for Proximal Humerus Fractures: Is there Clinical Improvement? / Consolidação dos tubérculos na artroplastia reversa do ombro após fratura proximal do úmero: Existe melhoria nos resultados funcionais?

Abstract Objective To compare the functional results of patients with complex proximal humerus fracture submitted to total shoulder reverse arthroplasty with and without tuberosity healing. The secondary goal was to know the tuberosity healing rate after reverse shoulder arthroplasty with our surgical technique. Methods A retrospective, cohort type study, with a prospective database collection. In total, 28 patients fulfilled the inclusion criteria: age ≥ 65 years, reverse shoulder arthroplasty for complex proximal humerus fracture (type-3 or -4, according to Neer), and a minimum of 24 months of follow-up. At six months of follow-up, all of the patients were evaluated radiographically for tuberosity, and then they were divided into 2 groups: those with healed tuberosities and those with non-healed tuberosities. A clinical evaluation using the Constant score, active range of motion and the Visual Analog Scale (VAS) at the last follow-up was also performed. Results Tuberosity healing occurred in 21 patients (76.3%). There were statistically significant differences in the Constant scoring system (p < 0.001), forward elevation (p = 0.020), internal rotation (p = 0.001) and external rotation (p = 0.003) when comparing the group of healed tuberosities with the group of non-healed tuberosities. No differences were found regarding the VAS score. Conclusion Tuberosity healing results in an improvement of the functional outcomes of patients submitted to reverse shoulder arthroplasty as a treatment for complex proximal humeral fractures in the elderly.

Resumo Objetivo Comparar os resultados funcionais entre pacientes com fratura complexa do úmero proximal submetidos a artroplastia reversa com tubérculos consolidados e tubérculos não consolidados. O objetivo secundário foi determinar a taxa de consolidação dos tubérculos com este tipo de prótese. Métodos Estudo de tipo coorte, retrospectivo, com coleta prospectiva de dados. No total, 28 pacientes cumpriram os critérios de inclusão: idade superior a 65 anos, prótese reversa do ombro por fratura complexa do úmero proximal (3 ou 4 partes, segundo Neer), e tempo de seguimento mínimo de 24 meses. Aos seis meses, todos os pacientes foram avaliados radiograficamente quanto à consolidação dos tubérculos e divididos em dois grupos: grupo com tubérculos consolidados e grupo com tubérculos não consolidados. A avaliação funcional realizou-se segundo o sistema de pontuação de Constant, da amplitude de movimento ativo, e da Escala Visual Analógica (EVA) à data da última consulta. Registaram-se todas as complicações. Resultados A consolidação dos tubérculos ocorreu em 21 pacientes (76,3%). Verificou-se diferenças estatisticamente significativas no sistema de pontuação de Constant (p < 0.001), elevação anterior (p = 0.020), rotação interna (p = 0.001) e externa (p = 0.003), quando se comparou o grupo dos tubérculos consolidados com o grupo dos tubérculos não consolidados. Não houve diferenças significativas na EVA entre os 2 grupos. Conclusão A consolidação dos tubérculos traduz uma melhoria dos resultados funcionais em pacientes submetidos a artroplastia reversa do ombro como tratamento de fraturas complexas do úmero proximal em idosos.

Tratamento cirúrgico da rizartrose: trapezectomia com ou sem ligamentoplastia versus prótese total / Surgical treatment of rhizarthrosis: trapeziectomy with or without ligamentoplasty versus total prosthesis

OBJETIVO: O objetivo deste estudo consiste em rever os casos submetidos a tratamento cirúrgico por duas técnicas: trapezectomia com ou sem ligamentoplastia e artroplastia com implante. MÉTODOS: Foram avaliadas 52 mãos tratadas cirurgicamente por rizartrose entre 1995 a 2008: 32 trapezectomias com ou sem ligamentoplastia (grupo A) e 20 artroplastias com implante (grupo B). Follow-up médio: grupo A - 72 meses, grupo B - 23 meses. Não houve resultados significativamente diferentes quanto à dor, atividades da vida diária, mobilidade e força. No estudo radiográfico, a altura escafometacarpiana foi mais preservada no grupo B. O tempo médio de recuperação foi de 10 semanas no grupo A e de 4,5 no grupo B. Foram registradas quatro complicações: um caso de algoneurodistrofia no grupo A e 2 casos de luxação e um caso de fratura do trapézio no grupo B. RESULTADOS: O resultado das próteses superam o tratamento tradicional da rizartrose com trapezectomia com ou sem ligamentoplastia pela rápida recuperação que proporcionam. CONCLUSÃO: Contudo, a sua aplicação deve ser criteriosa, pois existe potencial de complicações relacionadas com os implantes.

OBJECTIVE: The aim of this study was to review cases that underwent surgical treatment using two techniques: trapeziectomy with or without ligamentoplasty and arthroplasty with implant. METHODS: Fifty-two hands that were surgically treated for rhizarthrosis between 1995 and 2008 were evaluated: 32 cases of trapeziectomy with or without ligamentoplasty (group A) and 20 with implant arthroplasty (group B). The mean follow-up for group A was 72 months and for group B, 23 months. There were no significantly different results with regard to pain, activities of daily living, mobility or strength. In the radiographic evaluation, it was found that the scaphometacarpal height was better preserved in group B. The mean time taken to achieve recovery was 10 weeks in group A and 4.5 in group B. Four cases with complications were recorded: one case of algoneurodystrophy in group A and two cases of dislocation and one case of fracture of the trapezium in group B. RESULTS: The results from prostheses were better than the results from the traditional treatment for rhizarthrosis using trapeziectomy with or without ligamentoplasty because of the rapid recovery that prostheses provide. CONCLUSION: However, prostheses should be applied carefully, because there is a potential for complications relating to the implants.

Bilateral posterior fracture-dislocation of the shoulder: Report of two cases.

Bilateral posterior fracture-dislocation of the shoulder is a very rare injury. Almost 50% of bilateral posterior dislocations are due to a convulsive seizure, rising to 90% if the dislocations are associated with fractures. Electric shock accounts for less than 5% of bilateral posterior dislocations of the shoulder. A systematization of the clinical and radiological approach, followed by an early diagnosis and proper surgical treatment is essential. Authors report 2 cases of bilateral posterior fracture-dislocation of the shoulder, one caused by a convulsive seizure and the other by an electric shock. A review of literature and a treatment protocol are also presented.
