Great tuberosity fixation does not affect healing and clinical outcomes in RSA performed in proximal humeral fractures in elderly patients. Musculoskelet Surg 2024; 108:107-114. [PMID: 38175393 DOI: 10.1007/s12306-023-00807-9] [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: 06/16/2022] [Accepted: 12/05/2023] [Indexed: 01/05/2024]
Abstract
PURPOSE Aims of our study were to define whether the great tuberosity (GT) positioning fixation in reverse shoulder arthroplasty (RSA) after proximal humeral fracture (PHF) could predict tuberosity healing and its impact on clinical outcomes. METHODS We enrolled 59 patients treated with cementless reverse shoulder arthroplasty after PHF in our institute between 2012 and 2018. The mean follow-up was 57 months (± 23.4). We divided patients into two groups according to GT positioning after fixation: Group 1 GT in contact and Group 2 GT detached at least 1 mm from humeral diaphysis. Clinical and radiographic evaluations were conducted at last follow-up. RESULTS Overall GT healing rate was 64.4%, (Group 1 70.7%-Group 2 50%). A statistically significant difference (P = 0.047) was found in cortical thickness narrowing at one-third of stem length. We found a correlation between lateral cortical narrowing and GT fixation in non-anatomical position, but we observed no statistically significant differences about GT healing according to GT anatomical or non-anatomical fixation. No differences were found in shoulder function in patients whose tuberosity was healed or failed to heal. CONCLUSION GT reduction is not a predictive factor for GT healing; external stress shielding, instead, seems to be decreased in patients with postoperative anatomically reduced GT. In our study, GT healing did not affect clinical outcomes or patient's satisfaction in elderly low-demanding patients.

High satisfaction rate and range of motion can be expected in frozen shoulder after awake manipulation with brachial plexus block. J Orthop Traumatol 2024; 25:3. [PMID: 38282068 PMCID: PMC10822830 DOI: 10.1186/s10195-024-00747-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/12/2023] [Accepted: 01/01/2024] [Indexed: 01/30/2024] Open
Abstract
BACKGROUND Adhesive capsulitis (AC) is a disease of the glenohumeral joint that is characterized by pain and both passive and active global stiffness with a slow and insidious onset. The disease can occur spontaneously (primary AC) or it can be secondary to other comorbidities, surgery, or trauma, such as fracture or dislocation. Multiple treatment approaches have been suggested: intra-articular steroid injection, physical therapy, manipulation under total anesthesia, and arthroscopic or open surgery. Shoulder manipulation under anesthesia is usually proposed to patients that suffer from severe AC and have already undergone several nonoperative treatments without benefit. Different techniques have been proposed. This study presents our manipulation technique and the clinical results we achieved after shoulder mobilization under brachial plexus block in patients with phase III primary AC. MATERIALS AND METHODS A retrospective cohort study was performed on a sample of 110 patients with phase III AC who were treated with this manipulation and followed up for 1 year. Patients underwent two assessments-before the procedure (T0) and 4 months after it (T1)-based on the Numerical Rating Scale, Simple Shoulder Test, and joint range of motion to assess shoulder pain, function, and joint articulation, respectively. Furthermore, the patients had to express their degree of satisfaction with the procedure and the results achieved. RESULTS Positive and statistically significant results were recorded in terms of pain reduction (ΔNPRS = - 5.4; p < 0.01) and improved functionality (Simple Shoulder Test Δ = 5; p < 0.01). Passive range of motion was statistically significantly increased for each movement at T1. Large increases were observed in extrarotation range of motion (ROM): R1 (Δ = 77.5°) and R2 (Δ = 70°), whereas little improvements were observed in intrarotation ROM. Patients achieved satisfying functional and articular recovery in all cases. Complications that needed further treatment occurred in three cases: a brachial plexus injury, a glenoid flake fracture, and persistent pain and stiffness. CONCLUSIONS In this study, we proposed a standardized method of manipulation under brachial plexus block for patients affected by phase III adhesive capsulitis. The technique was applied among a large cohort of patients, who reported a high satisfaction rate and range-of-motion recovery after 4 months. This could represent an alternative treatment to surgery that has a shorter timeline and does not require patient hospitalization. LEVEL OF EVIDENCE Level III, retrospective cohort study.

Neuromuscular Electrical Stimulation-Enhanced Physical Therapist Intervention for Functional Posterior Shoulder Instability (Type B1): A Multicenter Randomized Controlled Trial. Phys Ther 2024; 104:pzad145. [PMID: 37870503 PMCID: PMC10824628 DOI: 10.1093/ptj/pzad145] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/18/2022] [Revised: 05/26/2023] [Accepted: 10/18/2023] [Indexed: 10/24/2023]
Abstract
OBJECTIVE Functional posterior shoulder instability (FPSI) (type B1) is a severe type of instability, mainly in teenagers and young adults, that leads to loss of function, pain, and stigmatization among peers. An experimental nonsurgical treatment protocol based on neuromuscular electrical stimulation (NMES) showed very promising early results in the treatment of FPSI. The hypothesis of this study was that NMES-enhanced physical therapy leads to better outcomes than physical therapy alone as the current gold standard of treatment in patients with FPSI. METHODS In this multicenter randomized controlled trial, patients with FPSI were randomly allocated in a 1:1 ratio to either 6 weeks of physical therapy or 6 weeks of physical therapy with simultaneous motion-triggered NMES. Baseline scores as well as outcome scores at 6 weeks, 3 months, 6 months, and 12 months after the intervention were obtained. The predefined primary outcome of this trial was the Western Ontario Shoulder Instability Index (WOSI) at the 3-month time point. RESULTS Forty-nine patients were randomized and eligible for the trial. The group that received physical therapy with simultaneous motion-triggered NMES showed a significantly better main outcome measurement in terms of the 3-month WOSI score (64% [SD = 16%] vs 51% [SD = 24%]). Two-thirds of the patients from the physical therapist group crossed over to the group that received physical therapy with simultaneous motion-triggered NMES due to dissatisfaction after the 3-month follow-up and showed a significant increase in their WOSI score from 49% [SD = 8%] to 67% [SD = 24%]. The frequency of instability episodes showed a significant improvement in the group that received physical therapy with simultaneous motion-triggered NMES at the 3-month follow-up and beyond, while in the physical therapist group, no significant difference was observed. CONCLUSION The current study shows that NMES-enhanced physical therapy led to statistically significant and clinically relevant improvement in outcomes in the treatment of FPSI compared to conventional physical therapy alone-from which even patients with prior unsatisfactory results after conventional physical therapy can benefit. IMPACT Based on the results of this study, NMES-enhanced physical therapy is an effective new treatment option for FPSI, a severe type of shoulder instability. NMES-enhanced physical therapy should be preferred over conventional physical therapy for the treatment of patients with FPSI.

Reverse shoulder arthroplasty in obstetric brachial plexus injury: our experience with shoulder motion analysis. J Orthop Traumatol 2023; 24:59. [PMID: 37947898 PMCID: PMC10638338 DOI: 10.1186/s10195-023-00736-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/11/2023] [Accepted: 10/18/2023] [Indexed: 11/12/2023] Open
Abstract
BACKGROUND Obstetric brachial plexus injury (OBPI) is a weakening or paralysis of the upper arm caused by brachial plexus injury followed by a muscle paralysis with severe repercussions on the movement of the shoulder joint following a progressive glenohumeral joint deformity. This case series analyzes the clinical and radiological outcomes of reverse total shoulder arthroplasty (RSA) in OBPI patients with a follow-up of 2 years. MATERIALS AND METHODS OBPI patients with secondary end-stage glenohumeral arthritis were enrolled in the study and they were treated with RSA. Patient demographics and clinical outcomes [Range of Motion (ROM), Visual Analog Scale (VAS), Oxford Shoulder Score (OSS)] were evaluated. A novel Shoulder motion analysis was carried out to investigate specific movement patterns of scapulothoracic movements in these patients. This study is a prospective cohort study. RESULTS Four Patients (M: F = 1:3) were enrolled in the study, the mean age was 49.3 years (+ 2.75), the mean OSS (Oxford Shoulder Score) decreased from 48.8 (± 2.5) preoperatively to 18.30 (± 2.78), the mean VAS (Visual Analog Scale) decreased from 7.25 (± 0.5) to 1.7 (± 0.3) in the follow up (∆% relative pain reduction:- 76.5%), Shoulder ROM obtained an improvement (p < 0.05) except for abduction and external rotation. The average follow-up time was 26.3 months (+- 4.5). Shoulder motion analysis showed a complete loss of the scapular tilting above 90 degrees of flexion compared to the typical one of standard RSA with a pattern shifted towards scapular retraction (engaging trapezius and rhomboid muscles) to compensate the loss of the posterior tilting. CONCLUSIONS RSA in OBPI patients demonstrated a significant improvement of pain symptoms and a moderate improvement in daily activities, anyway with a more appreciable quality of life over time even if the marked hypotrophy especially of the posterior shoulder muscles showed some limits in maintaining suspension of the upper limb and a minor external rotation, with an internal rotation attitude during the movements.

BIO-RSA vs. metal-augmented baseplate in shoulder osteoarthritis with multiplanar glenoid deformity: a comparative study of radiographic findings and patient outcomes. J Shoulder Elbow Surg 2023; 32:2264-2275. [PMID: 37263484 DOI: 10.1016/j.jse.2023.04.028] [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: 12/22/2022] [Revised: 04/16/2023] [Accepted: 04/19/2023] [Indexed: 06/03/2023]
Abstract
BACKGROUND Reverse shoulder arthroplasty (RSA) requiring extensive reaming to address severe glenoid bone loss increases the risk of glenoid medialization and baseplate failure. We hypothesized that (1) metal-augmented baseplate prevents the medialization of the joint line and preserves glenoid bone stock similarly to bony increased-offset (BIO)-RSA and (2) bone graft viability and healing in BIO-RSA patients become compromised over time. MATERIALS AND METHODS Eighty-one patients (83 shoulders) underwent glenoid lateralization with bone (BIO-RSA group, 44) or metal-augmented baseplate (metallic increased-offset [MIO]-RSA group, 39) and a minimum follow-up of 24 months were included. The orientation and direction of glenoid erosion was identified and recorded using computerized 3D planning. Active range of motion, and the Western Ontario Osteoarthritis of the Shoulder (WOOS) index were assessed before arthroplasty and at the last follow-up visits. Radiographic changes around the glenoid and humeral components were assessed. Healing and thickness of bone graft were evaluated by predefined criteria. Postoperative global glenoid inclination (β angle) and retroversion were also measured. RESULTS Delta scores of active anterior elevation were higher in the MIO-RSA group (P = .027). The differences in the other planes of shoulder motion and in WOOS index scores between the groups were not significant. Preoperative glenoid retroversion was higher in BIO-RSA patients, and glenoid inclination was similar in both groups. Type B2 and B3 glenoids had a posterior-central (91%) and posterior-superior (90%) erosion with a mean posterior humeral head subluxation of 76% and 78%, respectively. The direction of erosion in type E2 and E3 glenoids was posterior-superior, with a mean posterior humeral head subluxation of 74%. The rate of high position of the glenosphere was higher in the BIO-RSA group (P = .022), whereas the values of β angle and postoperative retroversion were similar in the 2 groups. BIO-RSA group showed radiolucent lines <2 mm around the bone graft in 16 patients (36.4%) and decreased thickness in 15 (34.1%). Incomplete baseplate seating was found in 4 MIO-RSA patients (10%). We found higher rates of humerus condensation lines in MIO-RSA patients (P = .01) and higher rates of cortical thinning and tuberosity resorption in the BIO-RSA group (P = .027 and P = .004, respectively). CONCLUSION Metal-augmented glenoid is a suitable alternative to BIO-RSA to preserve bone and prevent the medialization of the joint line in arthritic glenoid with multiplanar glenoid deformity. Bone and metal augmentation provided satisfactory clinical outcomes. Bone graft resorption in BIO-RSA patients raise concern about the risk of baseplate loosening and requires further long-term studies.

Navigation in reverse shoulder arthroplasty: how the lateralization of glenosphere can affect the clinical outcome. Arch Orthop Trauma Surg 2023; 143:5649-5656. [PMID: 37074371 PMCID: PMC10115375 DOI: 10.1007/s00402-023-04879-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/14/2023] [Accepted: 04/04/2023] [Indexed: 04/20/2023]
Abstract
INTRODUCTION One of the main causes of RSA failure is attributable to the malpositioning of the glenoid component. Initial experiences with computer-assisted surgery have shown promising results in increasing the accuracy and repeatability of placement of the glenoid component and screws. The aim of this study was to evaluate the functional clinical results, in terms of joint mobility and pain, by correlating them with intraoperative data regarding the positioning of the glenoid component. The hypothesis was that the lateralization more than 25 mm of the glenosphere can led to better stability of the prosthesis but should pay in term of a reduced range of movement and increased pain. MATERIALS AND METHODS 50 patients were enrolled between October 2018 and May 2022; they underwent RSA implantation assisted by GPS navigation system. Active ROM, ASES score and VAS pain scale were recorded before surgery. Preoperative data about glenoid inclination and version were collected by pre-op X-Rays an CT. Intraoperative data-inclination, version, medialization and lateralization of the glenoid component-were recorded using computer-assisted surgery. 46 patients had been further clinically and radiographically re-evaluated at 3-months, 6-months, 1-year, and 2-years follow-up. RESULTS We found a statistically significant correlation between anteposition and glenosphere lateralization value (DM - 6.057 mm; p = 0.043). Furthermore a statistically significant correlation has been shown between abduction movement and the lateralization value (DM - 7.723 mm; p = 0.015). No other statistically significant associations were found when comparing the values of glenoid inclination and version with the range of motion achieved by the patients after reverse shoulder arthroplasty. CONCLUSION We observed that the patients with the best anteposition and abduction results had a glenosphere lateralization between 18 and 22 mm. When increasing the lateralization above 22 mm or reducing it below 18 mm, on the other hand, both movements considered decreased their range.

Midterm Clinical Outcomes After Arthroscopic Rotator Cuff Repair in Olympic Volleyball Players: Return to Sports and Return to Performance. Orthop J Sports Med 2023; 11:23259671231186820. [PMID: 37655246 PMCID: PMC10467408 DOI: 10.1177/23259671231186820] [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: 03/16/2023] [Accepted: 04/13/2023] [Indexed: 09/02/2023] Open
Abstract
Background The decision-making process and predicting the time to return to sport (RTS) and return to performance (RTP) after arthroscopic rotator cuff repair (ARCR) in elite volleyball players are difficult issues to address, even among experienced shoulder surgeons. Purpose/Hypothesis The purpose of the study was to evaluate the results in Olympic-level volleyball players treated with arthroscopic supraspinatus repair and to report the RTS and the RTP. It was hypothesized that these athletes had higher RTS and faster RTP. Study Design Case series; Level of evidence, 4. Methods This study included 17 elite volleyball athletes (11 male, 6 female; mean age, 26.2 years) who underwent ARCR for partial- and full-thickness supraspinatus tears that did not improve despite nonoperative treatment. The clinical results were evaluated at 12 months postoperatively. The authors compared the athletes' preoperative, 6-month, and 12-month Kerlan-Jobe Orthopaedic Clinic (KJOC) scores and the visual analog scale (VAS) for pain after competition and conducted 6- and 12-month isometric strength analyses. The athletes' RTS and RTP times were recorded. Results All tears were on the dominant side (15 right, 2 left), and 82% were partial tears (14 partial thickness, 3 full thickness). The mean time from the onset of symptoms to surgery was 11.3 ± 6.7 months. While the mean Kerlan-Jobe Orthopaedic Clinic score was 31 preoperatively, it was 89 after 6 months (P < .001 vs preoperative) and 96 after 12 months (P = .003 vs 6 months). The mean VAS for pain was 7.9 preoperatively, 0.4 at 6 months (P < .001 vs preoperative), and 0.1 at 12 months (P = .02 vs 6 months). All athletes were able to reach their preinjury level, with RTS at a mean of 6.9 months and RTP at a mean of 12.4 months. Conclusion ARCR appears to be an effective option for Olympic-level volleyball players who do not benefit from nonoperative treatment. All athletes returned to their preinjury level of sports. The surgeon and athlete can plan surgical decision-making and timing based on the mean RTS time of 6.9 months and mean RTP time of 12.4 months.

Abstract
Revision shoulder surgery is always a challenge, especially in the management of periprosthetic joint infection. Staged surgery with antibiotic-loaded cement spacer, seems to yield satisfactory and encouraging results. New technologies such as computer navigation are additional tools that could aid surgeons in particular conditions where the native anatomy is distorted. This study presents the unique experience of revision shoulder surgery with computer navigation assistance. Benefits related to this approach could lead to better prosthesis longevity and survivorship.

Study of a constrained finite element elbow prosthesis: the influence of the implant placement. J Orthop Traumatol 2023; 24:15.

Abstract
BACKGROUND The functional results of total elbow arthroplasty (TEA) are controversial and the medium- to long-term revision rates are relatively high. The aim of the present study was to analyze the stresses of TEA in its classic configuration, identify the areas of greatest stress in the prosthesis-bone-cement interface, and evaluate the most wearing working conditions. MATERIALS AND METHODS By means of a reverse engineering process and using a 3D laser scanner, CAD (computer-aided drafting) models of a constrained elbow prosthesis were acquired. These CAD models were developed and their elastic properties, resistance, and stresses were studied through finite element analysis (finite element method-FEM). The obtained 3D elbow-prosthesis model was then evaluated in cyclic flexion-extension movements (> 10 million cycles). We highlighted the configuration of the angle at which the highest stresses and the areas most at risk of implant mobilization develop. Finally, we performed a quantitative study of the stress state after varying the positioning of the stem of the ulnar component in the sagittal plane by ± 3°. RESULTS The greatest von Mises stress state in the bone component for the 90° working configuration was 3.1635 MPa, which occurred in the most proximal portion of the humeral blade and in the proximal middle third of the shaft. At the ulnar level, peaks of 4.1763 MPa were recorded at the proximal coronoid/metaepiphysis level. The minimum elastic resistance and therefore the greatest stress states were recorded in the bone region at the apex of the ulnar stem (0.001967 MPa). The results of the analysis for the working configurations at 0° and 145° showed significant reductions in the stress states for both prosthetic components; similarly, varying the positioning of the ulnar component at 90° (- 3° in the sagittal plane, 0° in the frontal plane) resulted in better working conditions with a greater resulting developed force and a lower stress peak in the ulnar cement. CONCLUSION The areas of greatest stress occur in specific regions of the ulnar and humeral components at the bone-cement-prosthesis interface. The heaviest configuration in terms of stresses was when the elbow was flexed at 90°. Variations in the positioning in the sagittal plane can mechanically affect the movement, possibly resulting in longer survival of the implant. LEVEL OF EVIDENCE: 5

Scapulohumeral rhythm in shoulders with reverse shoulder arthroplasty measured with a new portable three-dimensional scapular kinematics assessment system. J Shoulder Elbow Surg 2023; 32:729-737.

Abstract
BACKGROUND Reverse shoulder arthroplasty (RSA) is a valid and increasingly popular treatment option in eccentric arthrosis and cuff arthropathy. We know that the deltoid is the motor of RSA. However, the role of scapular motion has been poorly documented in the literature. The aim of our study is to analyze and quantify the role of the scapular contribution in the functional outcome of patients undergoing RSA. MATERIALS AND METHODS Fourteen patients who underwent primary RSA were included in the study. In all cases, a reverse prosthesis with lateralizing stem was implanted. All patients underwent clinical examination, video recording, and motion analysis. X-ray and postoperative CT examinations were collected to evaluate positioning and any loosening. ShowMotion (NCS Lab srl, Modena, Italy) 3D kinematic tracking system was used to evaluate and measure the scapular motion in 3 planes. RESULTS All patients show substantial amount of posterior tilting and lateral rotation starting at 30° in forward elevation. A further difference is the anticipation of the retraction during the range of motion in the RSA side. The contribution of scapular motion in the RSA shoulder was greater than in the healthy shoulder. In patients with bilateral RSA, the contribution of scapular motion was higher in tilting and lateral rotation in the worse shoulder side in terms of range of motion. This means that to compensate for the loss of glenohumeral motion in RSA, more scapula-thoracic motion is needed to obtain the same thoraco-humeral elevation angle. CONCLUSIONS In the light of what has been measured, the post-RSA scapular kinematics has typical characteristics that must be achieved in order to obtain a good functional outcome. We can conclude that on the RSA side, the patients anticipate upward rotation both in flexion and abduction. The contribution of the upward rotation to elevation in the RSA group is therefore more significant. In addition to this, to facilitate elevation movements, there is an anticipation of the scapular retraction and a more prominent tilt resulting in different scapular kinematics. The analysis of scapular motion could be useful in the postoperative follow-up of patients undergoing RSA surgery and improve adaptative physiotherapy protocols. It potentially can even be included in future arthroplasty planning systems.

Anatomically reduced fixation should always be considered when treating B and C proximal epiphyseal humeral fractures. J Orthop Traumatol 2022; 23:51.

Abstract
Background Proximal humeral fractures are commonly observed in elderly patients. Management of these injuries is controversial. Literature comparing locking plate fixation, arthroplasty, and conservative treatments show no clear advantages for any of these management strategies. Thus far, no study has considered anatomically reduced fractures obtained after locking plate treatment. To clarify the best surgical procedure in middle-aged patients, we considered outcomes and major complications leading to surgical revision following an anatomically reduced fracture fixed with locking plate and reverse shoulder arthroplasty (RSA) in the treatment of type B/C fractures in patients between 50 and 75 years of age. Methods This is a retrospective study including 59 patients between 50 and 75 years of age with type B/C proximal humeral fracture treated with RSA or with locking plate fixation (resulting in an anatomical reduction) between January 2010 and December 2018. Preoperative radiographs and computed tomography (CT) were evaluated in all patients. Clinical and radiologic follow-up was performed using range of motion (ROM), the Constant–Murley Score (CMS), the Oxford Shoulder Score (OSS), the Simple Shoulder Test (SST), the Subjective Shoulder Value (SSV), and visual analog scale (VAS). Major complications were considered. Results In the plate fixation group, ROM, CMS, SST, and VAS were higher than in the RSA group. Lower complication rates compared with the literature were observed in both groups. Anatomically reduced fracture fixed with plate and screw could outperform RSA in terms of outcome. In second-level centers where traumatology is performed by surgeons with great expertise in upper limb trauma, the choice between plate fixation and reverse arthroplasty should be made during surgery. Conclusion Anatomically reduced fractures showed better outcomes compared with RSA in type B/C fractures. Surgeons should always try to perform a reduction of the fracture in order to understand if a plate fixation could be feasible. If it is impossible to perform an anatomical reduction, we suggest to consider RSA. This is a retrospective observational study.

Abstract
Background During the last decades, the growing number of shoulder replacement has increased the associated complications. Periprosthetic fractures have a low incidence but can be a severe clinical condition, especially in elderly population. There are still no guidelines to define the best treatment protocol for post-operative periprosthetic humeral fractures. Factors associated to these fractures and consequently the decision-making for the best treatment seem to be patient-related but also correlated with the type of implant. The aim of this study is to analyze the patient’s risk factors, fracture pattern, implant type and treatment, evaluating the outcome with a long-term follow-up. Methods A retrospective study was performed on more than 2700 shoulder prostheses implanted over 10 years in two specialized centers, identifying 19 patients who underwent surgery for post-operative periprosthetic fracture. Gender, age, comorbidities, type of prosthetic implant, type of fracture, and cortical index of each patient were evaluated. All patients underwent surgery and were evaluated with a mean follow-up of 5 years with radiographic controls and functional assessment with the Constant–Murley score. Results Complete healing was achieved in 18 of 19 patients. All patients presented a lower Constant–Murley score than the pre-fracture score, there were no significant differences between prosthetic implants, and the cortical index was lower than the threshold level in more than 60% of cases. Conclusion The results of this study showed that a correct preoperative planning is essential to evaluate the type of implant and possible signs of stem mobilization. With a stable stem, it is preferable to maintain it and proceed to a synthesis. The decision process is more complex in periprosthetic fractures with a reduced cortical index, when some radiolucency lines are present in stems with high primary stability, because it is not always indicative of an unstable stem.

Supracondylar fractures in children: management and treatment. ACTA BIO-MEDICA : ATENEI PARMENSIS 2021; 92:e2021015. [PMID: 34313666 PMCID: PMC8420822 DOI: 10.23750/abm.v92is3.11725] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 05/03/2021] [Accepted: 05/07/2021] [Indexed: 11/23/2022]
Abstract
Supracondylar humeral fractures are widely considered the most common elbow fracture in children. Gartland classification plays a fundamental role in decision-making regarding management and prognosis. Recent literature recommends conservative management for non or minimally displaced fractures, whereas there seems to be a trend towards surgical treatment for all displaced fractures. The preferred treatment for displaced Gartland II and Gartland III fractures is closed reduction and percutaneous fixation with lateral pins. In particular patterns medial pin is recommended for obtain a stable construct. Neurovascular complications are mostly associated with Type III fractures and sometimes surgical exploration with fracture reduction is needed. Correct diagnosis and proper management protocol is mandatory for avoid early and late complications such as neurovascular impairment and malunion.

Implant sonication versus intraoperative tissue sample cultures for Periprosthetic Joint Infection (PJI) of Shoulder Arthroplasty. ACTA BIO-MEDICA : ATENEI PARMENSIS 2021; 92:e2021009. [PMID: 34313671 PMCID: PMC8420828 DOI: 10.23750/abm.v92is3.11693] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Download PDF] [Subscribe] [Scholar Register] [Received: 04/27/2021] [Accepted: 05/17/2021] [Indexed: 11/24/2022]
Abstract
Introduction: Periprosthetic joint infection (PJI) is the most problematic complications after shoulder arthroplasty. Many diagnostic tools have been identified to find infection, such as hystopatologic examination of tissue sections or cultures of intraoperative tissue. Implant sonication fluid culture showed good results in order to enhance diagnostic accuracy, but literature results are still controversial. Aim of our study is to compare the results of sonication with intraoperative tissue sample cultures. Patients and Methods: From February 2016 to January 2018 we performed 102 revisions of Total Shoulder Arthroplasty (TSA) for suspected PJI. Sixty - five patients respected the criteria for admission to the study and were enrolled. In each case periprostethic specimens were collected and explanted prosthesis were put inside sterile fluid, sonicated and then placed under culture. Results: Among the sixty-five patients, 36 were considered as possible, probable or certain infection. Tissue cultures were positive for infection in thirty - four cases (52,3%) and in nineteen cases was found the positivity for Cutibacterium acnes. Sonication fluid cultures were positive in forty cases (61,5%), with a positivity for Cutibacterium acnes in twenty - seven cases. The sensitivities of sonication and tissue cultures for the diagnosis of shoulder PJI were 83.3% and 88,9% (P = 0,08); the specificities were 65.5% and 93,1% (P < 0.01) respectively. Conclusion: Our results suggest that sonication technique had not shown a clear advantage in postoperative shoulder PJI diagnosis, but it’s a real aid to detect Cutibacterium acnes. In any case, sensitivity and mostly specificity were higher with tissue cultures. (www.actabiomedica.it)

A kinematic and electromyographic comparison of a Grammont-style reverse arthroplasty combined with a l'Episcopo transfer compared to a lateralized humeral component reverse for restoration of active external rotation. INTERNATIONAL ORTHOPAEDICS 2021; 45:2061-2069. [PMID: 34212229 DOI: 10.1007/s00264-021-05122-1] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/26/2021] [Accepted: 06/16/2021] [Indexed: 11/24/2022]
Abstract
PURPOSE To assess kinematic and electromyographic findings of two designs of reverse total shoulder arthroplasty (RTSA). We tested two hypotheses: (H1) Grammont-style (RTSA) with l'Episcopo tendon transfer gains similar postoperative kinematic findings of a lateralized humeral component RTSA without a tendon transfer; (H2) RTSA with lateralized humeral component induces earlier shoulder muscle activation during shoulder motion compared with standard Grammont prosthesis with l'Episcopo transfer. METHODS Twenty-five patients with a cuff tear arthropathy, pseudoparalysis, and a positive dropping sign were sequentially included. A Grammont-style RTSA with a l'Episcopo tendon transfer was implanted in 13 patients (medialized humerus and transfer group) and an on-lay curved-stem RTSA in 12 (lateralized humerus group). Constant score; the disabilities of the arm, shoulder, and hand (DASH) score; and active shoulder range of motion (flexion, abduction, external rotation, and internal rotation) were measured pre- and postoperatively. Upper limb kinematic and surface electromyography (EMG) (anterior and posterior deltoid; upper, middle, and lower trapezius; and the upper and lower latissimus dorsi muscles) were recorded during active range of motion. RESULTS At > 24 months of follow-up, the Constant and DASH scores and active shoulder range of motion improved in both groups (p < 0.0001). Internal rotation was significantly higher in the lateralized humerus group than in the medialized humerus and transfer group (p = 0.004). The dropping sign was found in 0/12 patients in the lateralized humerus group and in 5/13 patients in the medialized humerus and transfer group (p < 0.001). Kinematic findings were similar between groups (p = 0.286). A pattern of earlier muscle activation in the lateralized humerus group was found as compared to the transfer group as follows: (i) posterior deltoid during external rotation (p = 0.004); (ii) upper latissimus dorsi and middle and lower trapezius during flexion (p = 0.004, p = 0.005, and p = 0.042, respectively); (iii) lower latissimus dorsi during abduction (p = 0.016). CONCLUSION RTSA with a lateralized humeral component provided similar active external rotation restoration to a Grammont-style RTSA with a l'Episcopo procedure in patients with a dropping sign. The posterior deltoid muscle underwent earlier activation during active external rotation in the lateralized humerus RTSA group as compared to the tendon transfer group. Our findings demonstrated the H1 and only partially demonstrated the H2 of the study.

Locked anterior glenohumeral dislocation: is it always recommendable a conservative treatment? Musculoskelet Surg 2021; 106:239-245. [PMID: 33683653 DOI: 10.1007/s12306-021-00702-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/03/2019] [Accepted: 02/14/2021] [Indexed: 11/30/2022]
Abstract
PURPOSE Chronic anterior shoulder dislocation represents a rare condition, and there is still lack of consensus in its treatment. Purpose of this study is to evaluate the clinical and radiological outcome of painful locked dislocation underwent shoulder replacement, with a minimum follow-up of two years. Second endpoint is to assess the glenoid bone graft, harvested from the humeral head. METHODS Eight patients underwent shoulder replacement for locked anterior shoulder dislocation. Four patients with a mean age of 23 y.o. were treated with Pyrocarbon-hemiarthroplasty and four patients with a mean age of 76 y.o. were treated with reverse shoulder arthroplasty. Glenoid single stage reconstruction was performed with a bone autograft harvested from the resected humeral head. Patients were observed for a clinical and radiological follow-up for a minimum period of 2 years; ASES and Constant score were assessed. RESULTS Pain and ROM improvement was reported in all the patients. In one case, postoperative recurrent RSA instability was found. Glenoid reconstruction was performed in seven cases, showing a good integration and no reabsorption issues in all but one cases. ASES and Constant-Murley functional outcomes were rated as excellent by 1 patient with pyrocarbon HA and 1 patient with RSA, good by 3 patients with RSA and 2 patients with HA, fair by 1 patient with HA and poor by one patient with RSA. CONCLUSION The treatment of locked anterior glenohumeral dislocation still represents a challenge in symptomatic patients. Shoulder replacement showed good results in young and older patients, with HA and RSA, respectively. Autograft from the humeral head is reliable for glenoid defect, even in ream and run procedure. Locked dislocation lasting more than one year, surgery is debatable for higher risk of a poor outcome and recurrent instability.

Abstract
BACKGROUND Soccer, the most popular sport worldwide, has seen an exponential increase in women's participation at the elite level in the last few years. The main purpose of the current epidemiological study was to analyze the injury incidence, characteristics, and burden among elite female soccer players during a regular season. METHODS We recorded all injuries that occurred throughout the 2018-2019 competitive soccer season (August-April). The studied group consisted of 22 elite players, who were militant in the first national leagues from the first team of the same soccer club in the north of Italy. The 2006 FIFA consensus statement was used to design the injury registration form. RESULTS Throughout the 2018-2019 season, medical staff treated 35 injuries in 22 females. Of the total number of injuries reported in 9 months (5.8 injuries per 1000 hours of exposure), 7 (20%) occurred during matches and 28 (80%) during training sessions. The most common injury was represented by muscular disorders (18; 51.43%) which affected the thigh in 16 cases, and the lower leg and trunk in one case each. According to an anatomic site, most injuries occurred in the lower limbs (94,28%), with the majority affecting thighs (16; 45%), ankles (8; 23%), and knees (5; 14%). CONCLUSIONS Non-contact injuries are shown to be more frequent than contact injuries, which may be connected to the increasing athletic burden among athletes. Further prospective investigations are needed with a focus on prevention protocols.

Abstract
INTRODUCTION Coronal shear fractures of the distal humerus represent an uncommon lesion and could be burdened by high complications. This complex lesion requires an accurate reduction and surgical fixation for a better outcome. Different techniques have been described, however no standard protocol have been proposed. Purpose of this retrospective study, is to evaluate the clinical and radiological outcome with posterior cannulated self-tapping headless screws followed by an early-active-motion protocol and to outline the surgical tips and tricks for different fracture patterns. MATERIALS AND METHODS From 2013 to 2019, a consecutive series of 24 patients with coronal shear fracture undergoing ORIF were included in the study. Fractures were classified according to Dubberley's classification. Cannulated self-tapping headless screws were used to fix the fragments. When necessary, additional cannulated half-threaded screws on the lateral edge of the humerus were used, as well as bone chips and fibrin sealant on severe comminution. All patients underwent an assisted early-active-motion rehabilitation protocol. Mean follow-up was 30 months; patients underwent standard X-rays and clinical outcome assessment with range of motion, Broberg and Morrey score and MEPI score. RESULTS Surgical fixation with headless screw guaranteed complete healing of all shear fractures examined, no loss of reduction were reported. ROM assessment showed good results with an average arc of 113.1°. Excellent to good Broberg-Morrey and MEPI score were reported. No cases of avascular necrosis nor post-traumatic osteoarthritis resulted in our series. Complications occurred in 16.6% of the patients. CONCLUSION Coronal shear fracture represents a challenging injury to treat. Anatomical reduction and the use of cannulated self-tapping headless screws from posterior provide a stable fixation, high union rates and good elbow function, with a low cartilage damage and risks of necrosis over 2 years of follow-up. LEVEL OF EVIDENCE Therapeutic III.

Abstract
The treatment of severe glenoid bone loss in shoulder arthroplasty represents a challenge, and the results of current prosthetic designs with only glenoid fixation still remain unsatisfactory. In the past decade, customized glenoid prostheses have been developed to address severe glenoid arthritis and in the revision setting. In this review, we analyzed the current surgical options, the classification limits, past literature evidence, and our preliminary results of 6 patients (3 male, 3 female) treated with a reverse implant and custom-made glenoid implant (ProMade; LimaCorporate, Italy). Computer analysis of the residual shape and the amount of glenoid bone stock in association with new classifications could help the surgeon to obtain good clinical and radiological outcomes. The development of navigation systems could improve the adequacy of the implant and, thus, the reliability and longevity of the implant itself.

The GLAD Lesion: are the definition, diagnosis and treatment up to date? A Systematic Review. ACTA BIO-MEDICA : ATENEI PARMENSIS 2020; 91:e2020020.

Abstract
INTRODUCTION Although GLAD lesions are quite common, only sporadic case reports describe surgical techniques and clinical outcomes. Even if cartilage defects can result from various pathogenic mechanisms, the resulting defect has some similarities with GLAD, and its management can be a starting point to treat both types of lesion. Aim of the present study is to find a commonly accepted definition for GLAD lesions in order to understand its pathogenesis, diagnosis and possible treatments. METHODS A search of PubMed (MEDLINE) database has been performed in June 2020 to identify relevant articles including a combination of the following search terms: "GlenoLabral Articular Disruption" OR "GLAD" AND "shoulder" AND "cartilage, articular". RESULTS Abstract evaluation included 31 articles in the full-text review. Various studies showed that the performance of MR arthrography in the detection of glenohumeral cartilage lesions, including GLAD lesions, was moderate. Different therapeutic solutions have been described. Arthroscopic debridement of the lesion and reattachment of the labrum have been often used. In case of large articular defects, the labrum could be advanced in the cartilage defect to cover it. In case of cartilage flap with reparable margins, this could be reattached with different suture constructs. Neglected GLAD lesions following a chronic trauma or shoulder instability have not been described in literature. CONCLUSIONS The definition of GLAD injury has changed over the time. Many authors associate this lesion with shoulder instability, with trauma in abduction and extra rotation, while Neviaser's original definition described stable shoulders following a trauma in adduction.

Abstract
PURPOSE Chronic anterior glenohumeral joint instability is a common situation and can lead to progressive cartilage deterioration and ultimately instability arthopathy. Progressive cartilage deterioration can occur despite conservative or surgical treatment and the sequelae of these conditions are often addressed with total shoulder arthroplasty. Aims of the present study were to analyze the available literature to describe the technical aspects of this particular operation and to report outcomes and complication rates. The hypothesis was that shoulder arthropalsty in the sequelae of instability had lower outcomes and higher complication rates than arthroplasties for primary arthritis. METHODS A systematic review of the literature was performed, in accordance with the PRISMA guidelines. PubMed, Ovid, Cochrane Reviews, and Google Scholar were comprehensively searched using a combination of the following keywords: shoulder arthroplasty, reverse shoulder arthroplasty, dislocation arthropathy, capsulorrhaphy arthropathy and stabilization procedures. RESULTS Thirteen studies with 365 patients met inclusion criteria. Since 13 patients were lost to follow-up, 352 were reviewed at an average follow-up of 53.4 months. The average Constant-Murley (CM) and American Shoulder and Elbow Society (ASES) scores improved from 35.6 and 35.7 to 72.7 and 77, respectively. The overall complication rate was 25.7% and the reoperation rate was 18.5%. Radiographs at follow-up revealed radiolucent lines on the humerus in 12.4% of cases and radiolucent lines or notching on the glenoid side in 22.7% of cases. The average Methodological Index for Non-randomized Studies Score (MINORS) was 12.9 for non-comparative studies and 21.3 for comparative studies. CONCLUSION Shoulder arthroplasty to address the sequelae of instability arthropathy and stabilization procedures can be a challenging procedure as a consequence of the distorted anatomy and severe glenohumeral joint pathology. Complication and reoperation rates are higher compared to shoulder arthroplasty for primary glenohumeral joint arthritis; however, the difference is not statistically significant. When reverse shoulder arthroplasties (RSA) were considered as a subgroup and compared to anatomic shoulder replacements (total shoulders and hemiarthroplasties), they showed a lower revision rate.

Abstract
BACKGROUND Radial head dislocation with no associated lesions, is a relatively uncommon injury in children. In this case report, it is reported a case of anteromedial locked radial head dislocation in children, and we discuss its clinical presentation and pathogenetic mechanism of injury. CASE PRESENTATION An 8-year-old girl fell off on her right forearm with her right elbow extended in hyperpronation. An isolated radio-capitellar dislocation was identified with no other fractures or neurovascular injuries associated. Elbow presented an extension-flexion arc limited (0°- 90°), and the prono-supination during general anesthesia shows "a sling effect" from maximal pronation (+ 55°) and supination (+ 90°) to neutral position of forearm. The radial head dislocation was impossible to reduce and an open reduction was performed using lateral Kocher approach. The radial head was found "button-holed" through the anterior capsule. The lateral soft tissues were severely disrupted and the annular ligament was not identifiable. Only by cutting the lateral bundle of the capsule was possible to reduce the joint. At 50 moths follow-up, patient presented a complete Range of motion (ROM), complete functionality and no discomfort or instability even during sport activities. DISCUSSION AND CONCLUSION It is important to understand the pathogenic mechanisms of locked radial head dislocation in children. Some mechanism described are the distal biceps tendon or the brachialis tendon interposition. However even the anterior capsule can hinder reduction. A characteristic "sling-effect" of the forearm could be pathognomonic for capsular button-holing. Surgical release of the capsular bundle sometimes is the only way to reduce the dislocation and obtain a good outcome.

Reinsertion of distal biceps ruptures with a single anterior approach: analysis of 14 cases using tension-slide technique and interference screw. ACTA BIO-MEDICA : ATENEI PARMENSIS 2020; 91:183-188. [PMID: 32555095 PMCID: PMC7944842 DOI: 10.23750/abm.v91i4-s.9551] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 04/16/2020] [Indexed: 12/05/2022]
Abstract
Background: Several techniques of surgical repair of biceps tendon ruptures are described in literature. Cortical button repair have shown minimal loss of elbow flexion, supination and strength. In this retrospective study we report the outcomes in terms of elbow function and complications of tension-slide technique and interference screw. Matherials and methods: 14 patients with complete distal biceps tendon rupture were included in the retrospective study and treated with the same tension-slide technique (BicepsButton® - Arthrex, Inc, Naples, Florida) evaluating the clinical and functional outcomes and the complication rate with a follow-up average of 18 months. Results: The flexion recovered compare to the healthy contralateral was 96% (min 115° - max 135°; average 128°), the extension was 97% (min: -2° - max 15°; average 4°), the supination was 90% (min 20° - max 90°; average 75°), the pronation was 95% (min 15° - max 90°; average 76°). The mean Disabilities of Arm, Shoulder and Hand (DASH) score was 8.1 ± 10.5 and Mayo Elbow Performance Score overall (MEPS) score was 97.6 ± 8.2. Two patients had LABCN paresthesia, one case, treated 2 months after injury, had posterior interosseus nerve palsy. One patient had heterotopic ossification at the radiological examination without consequences for the clinical performances. No case of non-traumatic tendon re-rupture and no case of ROM deficiency > 20%. In all case the cortical button remains well positioned and no case of osteolysis were reported. Conclusions: Distal biceps tendon repair with BicepsButton® system seems to be a safe, relyable and reproducible technique providing excellent clinical, functional and radiological outcomes. Comparing with other techniques the BicepsButton® system has the advantages of the single approach procedures, the reduction of surgical time and risk of heterotopic ossifications.

Abstract
Background: Despite rotator cuff repair techniques have developed significantly in last decade, pushed by the progress in technology and materials, the treatment of rotator cuff tears and re-tears is still a big challenge for shoulder surgeons. The aim of this study is to perform clinical and radiological evaluation (ultrasound and MRI) of patients treated with transosseous sharc-ft, and single row techniques for sovraspinatus rotator cuff tear at 6, 12 and 24 months follow up. Methods: Twenty-eight consecutive patients who underwent arthroscopic repair for rotator cuff tear were enrolled in the study and divided in two different groups: group A (14 patients) underwent a single row technique repair; group B (14 patients) underwent a transosseous sharc-ft technique repair. All participants had MRI or ultrasound examination confirmed full-thickness tears of sovraspinatus tendon before surgery. All the patients underwent clinical evaluation at 45 days, 3 months, 6 months, 12 and 24 months post-operatively with VAS, Dash, Constant and ASES score. Diagnostic ultrasound examination was performed at 6 months follow up while the MRI examination at 1 and 2 year follow up. Results: The whole primary variables didn’t show any significant difference and the groups were homogenous (age, Goutallier fatty infiltration, VAS, DASH, Constant, ASES). Some statistically significant differences are visible at discrete variables in a specific time: Dash at 12 months and Constant at 24 months show a significant improvement versus single-row technique. Conclusion: The arthroscopic transosseous repair technique with sharc-ft showed excellent results with little significant statically difference between this technique and the single row for this kind of lesion after 1 year of follow-up. Clinical data from this study confirmed, with the help of ultrasound examination and MRI, the excellent clinical outcome obtained by the patients. Further studies are needed to find differences between these techniques in the repair of large and massive rotator cuff lesions. (www.actabiomedica.it)

Abstract
BACKGROUND The aim of the present retrospective study was to evaluate complications following carbon-fiber-reinforced polyetheretherketon (CFR-PEEK) volar plating in distal radius fracture in a large cohort of patients. As an alternative to conventional metallic devices, CFR-PEEK plates have been introduced over the last few years. METHODS We performed a retrospective study including all patients who were treated for distal radius fracture using a volar fixed-angle plate DiPHOS-RM (Lima Corporate, Udine, Italy). All CFR-PEEK plates implanted were reviewed between May 2012 and December 2017. Plate removal, second surgery and adverse events were collected by reviewing medical records. A total of 110 patients were included with a mean follow-up of 4 years. RESULTS Adverse side effects were observed in 9 cases (8%), developed during or after treatment. The most frequent complication was represented by intraoperative plate rupture (4%). Infection was reported in one case. DISCUSSION The rate of complications of PEEK volar plates seems to be similar to those occurring with plates of different materials. Advantages of PEEK plates are the absence of the cold-welding phenomenon and the absence of exuberant bone callus on the plate, ensuring an easy hardware removal. Intraoperative rupture remains the main complication correlated with PEEK material. These complications can be reduced with an accurate surgical technique, especially at the beginning of the learning curve. LEVEL OF EVIDENCE Therapeutic IV.

Shoulder Function After Cardioverter-Defibrillator Implantation: 5-Year Follow-up. Ann Thorac Surg 2019; 110:608-614. [PMID: 31862496 DOI: 10.1016/j.athoracsur.2019.10.063] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/01/2019] [Revised: 09/24/2019] [Accepted: 10/11/2019] [Indexed: 11/30/2022]
Abstract
BACKGROUND Implantable cardioverter-defibrillator (ICD) represents the main tool for prevention of sudden cardiac death. Different kinds of postimplant complications have been described; however, little is known about shoulder functional impairment and its impact on quality of life. METHODS Patients with standard indications for elective prepectoral subcutaneous ICD insertion were enrolled during a 1-year period. The impact of ICD implantation on shoulder motility, pain, general disability, and quality of life was evaluated prospectively at baseline, and after 2 weeks, 3 months, 1 year, and 5 years using the Constant score, the Numeric Pain Rating Scale, the Disabilities of the Arm, Shoulder, and Hand scale, and the Short Form-36 Health Survey questionnaire. RESULTS A total of 50 patients underwent insertion of single, dual chamber, or biventricular ICDs. Two weeks after implantation, functional impairment and mild pain were observed in ipsilateral shoulder movements, with a reduction in the Short Form-36 Health Survey score. Shoulder functional impairment improved at the third-month evaluations, with almost normalization at 1-year and 5-year assessments, as well as pain and quality of life. CONCLUSIONS Prepectoral subcutaneous ICD implantation may be associated with ipsilateral shoulder functional impairment that regresses partially after 3 months and completely at 1-year and 5-year assessments. The less invasive implantation technique and the relatively small size of modern ICDs, independently from types and volumes, may be relevant to the degree of postimplantation shoulder functional impairment and recovery time. Shoulder function should be assessed at routine checks, especially soon after ICD implantation because of potential functional impairment and subsequent impact on quality of life.

Comparison between conservative treatment and plate fixation for displaced middle third clavicle fracture: clinical outcomes and complications. ACTA BIO-MEDICA : ATENEI PARMENSIS 2019; 90:48-53.

Abstract
Background: Clavicle fractures are common injuries in adults, especially due to sport activities or road traffic accidents. Most lesions occur at the level of the middle-third presenting some degree of displacement often. Traditionally, non-surgical management was considered the first treatment option for the most clavicle fractures. Nowadays, various authors suggest early surgical fixation of displaced midshaft fractures. The aim of this study is to compare surgical versus non-surgical treatment and to evaluate the outcomes and the incidence of complications following to both treatment options. Matherial and methods: 87 patients with 2 displaced clavicle fractures fragments (AO 15.2A) were included in the retrospective study, evaluating the clinical and functional outcomes and the complication rate with a follow-up average of 48 months. Results: The risk of nonunion resulted lower in the surgically treated patients. The Constant Score after 1 year was slightly better after the plate fixation (94,36 vs 91,36), while the DASH score resulted better in the conservatively treated patients (3,86 vs 4,63). The delay or revision surgery rates were similar for both groups and most of the complications were associated with the conservative treatment. Conclusions: According to our results, the plate fixation does not lead to better clinical and functional outcomes, instead it reduces the risk of nonunion. We suggest to tailor the treatment patient-by-patient considering the functional demand, patient’s comorbidity and nonunion risk factor. (www.actabiomedica.it)

A new plate design to treat displaced 3-4 parts proximal humeral fractures in comparison to the most tested and used plate: clinical and radiographic study. MEDICINSKI GLASNIK : OFFICIAL PUBLICATION OF THE MEDICAL ASSOCIATION OF ZENICA-DOBOJ CANTON, BOSNIA AND HERZEGOVINA 2019; 16.

Abstract
Aim Proximal humeral fractures are common and most complex patterns currently represent a challenge for surgeons. Difficulties in obtaining good anatomical reduction (particularly of great tuberosity) often lead to unsatisfactory results; choices often fall onto prosthesis implantation against fixation options. The aim of this study was to compare a new design of proximal humeral plate with the most used plates in the treatment of these injures by analysing outcomes and complications. Methods Two hundred patients with proximal 3 or 4 parts humeral fracture were enrolled (Neer 3-4). First group treated with PGR Plate composed of 98 patients. Second group treated with Philos Plate composed of 102 patients. Evaluation criteria were Non-Union Scoring System, duration of surgery, complications, objective quality of life and elbow function (Constant Shoulder Score), subjective quality of life and elbow function (Oxford Shoulder Score), post-op radiographs, centrum collum diaphyseal angle. Evaluation endpoint was 12 months. Results There was no statistically significant difference between the groups with regard to the selected evaluation parameters. Achievement of good shoulder range of motion and ability to perform normal daily living activities was obtained in both groups. The PGR had a positive impact on treatment results of varuspattern of proximal humeral fractures. Conclusions The PGR allowed good clinical and radiographic results in the treatment of proximal humeral fractures, comparable to those obtained with Philos. Also, PGR had the advantage to aid and keep the anatomical reduction of patterns of fracture involving the greater tuberosity.

Abstract
The advancement of technologies in orthopaedic surgery should provide the surgeon with precise and trustworthy support for pre-operative planning, intra-operative guidance and post-operative follow-up. The request for greater accuracy, predictable results and fewer complications, is the engine of digital evolution in pre-operative planning and computer-assisted surgery (CAS). It is an evolution rather than a revolution, and in the last few years these developments have begun to involve shoulder replacement surgery, too.

Abstract
PURPOSE Massive rotator cuff tears are common in the aging population. The incidence of failed rotator cuff repairs is still quite high, especially in the treatment of full-thickness tears or revision repairs. In this context, natural and synthetic meshes can be used as augmentation scaffolds or as devices to close the gap between a retracted tendon and the bone. The purpose of this work is to evaluate the ultimate tensile strength of different tendon-patch joints in order to consider their use in the treatment of massive cuff tears. MATERIALS AND METHODS Porcine tendons and a synthetic low-density polypropylene mesh have been used. A preliminary study on the tensile strength of tendons and patches has been performed. Different patch-tendon joints have been studied by modifying the number and the layout of the sutures. For every joint, the tensile test, performed through an electromechanical machine, has been repeated at least twice to obtain reliable data. RESULTS Experimental tensile tests on tendons and patches have given good results with very low dispersion data. Mean values of the calculated ultimate tensile stresses are, respectively, about 34 MPa and 16 MPa for tendons and patches. As regards the sutures arrangement, the staggered layout gave, for all joints, a higher tensile strength than the regular (aligned) one. Different ultimate tensile stress values, depending on the sutures number and layout, have been calculated for the joints. CONCLUSION Synthetic patches could be an interesting option to repair massive cuff tears and to improve, in a significant way, pain, range of motion and strength at time 0, so reducing the rehabilitation time. Obtained results demonstrated that joints with a suitable number and layout of sutures could ensure very good mechanical performances. The failure load of the tendon-patch joint, in fact, is higher than the working load on a healthy tendon.

Abstract
Irreparable rotator cuff tears are common conditions seen by shoulder surgeons, characterized by a torn and retracted tendon associated with muscle atrophy and impaired mobility. Direct fixation of the torn tendon is not possible due to the retracted tendon and lack of healing potential which result in poor outcome. Several treatment options are viable but correct indication is mandatory for a good result, pain improvement, and restoration of shoulder function. Patient can be treated either with a conservative program or surgically when necessary, by different available modalities like arthroscopic debridement, partial reconstruction, subacromial spacer, tendon transfer, and shoulder replacement with reverse prosthesis. The aim of this study was to review literature to give an overview of the available possible solutions, with indications and expected outcomes.

Abstract
BACKGROUND Metal plates are the fixation devices used most frequently to proximal humeral fractures (PHFs). However, in recent years carbon fiber-reinforced polyetheretherketone (CFR-PEEK) plates have become increasingly common. This study compares the clinical and radiographic outcomes of 42 Neer three- and four-part PHFs treated with CFR-PEEK or metal (titanium) plates. MATERIALS AND METHODS Forty-two PHF patients were managed with CFR-PEEK plates (n = 21, males/females 9/12; mean age 57.4 years; mean follow-up 30.7 months; CFR-PEEK group) or metal plates (n = 21; males/females 7/14; mean age 55.8 years; mean follow-up 52.7 months; Metal group). Active shoulder mobility (anterior elevation, lateral elevation, external rotation, and internal rotation), the Constant-Murley Score, the Simple Shoulder Test Score, and the pain score were recorded. Preoperative computed tomography scans and X-rays were obtained. Postoperative fracture healing and displacement, tuberosity resorption and/or malposition, hardware position, and cortical thinning (CT) under the plate were assessed radiographically. RESULTS Shoulder mobility, clinical, and pain scores were similar in both patient groups. CT was significantly greater in CFR-PEEK patients (mean difference, 1.14 mm; p = 0.0003). In both groups, incomplete or poor calcar reduction was associated to a significantly higher complication rate, especially stiffness and muscle weakness (p = 0.016). The rate of tuberosity resorption was significantly higher in the Metal group (p = 0.040). Two patients required revision to a hemiarthroplasty (CFR-PEEK) and reverse arthroplasty (Metal group). CONCLUSIONS CFR-PEEK plates provide a viable alternative to conventional titanium plates in PHFs, ensuring similar clinical outcomes and a lower rate of tuberosity resorption, but they involve higher stress shielding under the plate.

Assessment of return to play in professional overhead athletes subjected to arthroscopic repair of rotator cuff tears and associated labral injuries using the Italian version of the Kerlan-Jobe Orthopedic Clinic Shoulder and Elbow score. Musculoskelet Surg 2018; 102:29-34.

Abstract
BACKGROUND The self-administered Kerlan-Jobe Orthopedic Clinic (KJOC) Shoulder and Elbow questionnaire is a reliable and sensitive outcome tool to assess upper extremity athletic performance and functional changes affecting return to play in overhead athletes. We report the results of a study of return to sport in professional overhead athletes at a mean follow-up of 2 years after arthroscopic repair of rotator cuff tears and associated labral injuries using the Italian version of the score. MATERIALS AND METHODS A total number of 38 patients completed the 10-item questionnaire before and after surgery. They were also asked (1) whether they had returned to play; (2) how many months after the operation they had done so; (3) the level of postoperative performance (preinjury or less); and (4) whether they had had to change sport due to their shoulder problems. RESULTS Significant differences were found (1) between preoperative and postoperative scores; (2) between the scores of patients who returned to play at preinjury level and those who merely returned to competition; and (3) between the postoperative subscores of 8/10 items, which were higher in the patients who returned to preinjury performance than in those who merely returned to play; the two items that were not significantly different between these subgroups concerned pain and joint stability. Even though item analysis highlighted a major role for athletic performance in recovery of preinjury performance, it also stressed that the athlete's relationship with coach, agent, and staff and his/her feeling of the extent to which the arm affects current performance significantly contribute to the final score. CONCLUSIONS The KJOC Shoulder and Elbow score provides an accurate and exhaustive assessment of the recovery of the athlete's shoulder in relation to preinjury performance and provides the surgeon with key information on the pros and cons of surgical management.

Abstract
Background Surgical treatment of scapular fractures with posterior approach is frequently associated with postoperative infraspinatus hypotrophy and weakness. The aim of this retrospective study is to compare infraspinatus strength and functional outcomes in patients treated with the classic Judet versus modified Judet approach for scapular fracture. Patients and methods 20 cases with scapular neck and body fracture treated with posterior approach for lateral border plate fixation were reviewed. In 11 of 20 cases, we used the modified Judet approach (MJ group), and in 9 cases we used the classic Judet approach (CJ group). All fractures were classified according to the AO classification system. At follow-up examinations, patients had X-ray assessment with acromiohumeral distance (AHD) measurement, clinical evaluation, active range of motion (ROM) examination, Constant Shoulder Score, and Disability of the Arm, Shoulder and Hand (DASH) Score. Infraspinatus strength assessment was measured using a dynamometer during infraspinatus strength test (IST) and infraspinatus scapular retraction test (ISRT). Results Demographic data did not significantly differ between the CJ group and MJ group, except for mean follow-up, which was 4.15 years in the CJ group and 2.33 in the MJ group (p < 0.001). All X-ray examinations showed fracture healing. AHD was significantly decreased in the CJ group (p = 0.006). We did not find significant differences in active ROM between the MJ and CJ groups in the injured arm (p < 0.05). The Constant Score was 75.83 (±14.03) in the CJ group and 82.75 (±10.72) in the MJ group (p = 0.31); DASH Score was 10.16 in the CJ group and 6.25 in the MJ group (p = 0.49). IST showed mean strength of 8.38 kg (±1.75) in the MJ group and 4.61 kg (±1.98) in the CJ group (p = 0.002), ISRT test was 8.7 (±1.64) in the MJ group and 4.95 (±2.1) in the CJ group (p = 0.002). Infraspinatus hypotrophy was detected during inspection in six patients (five in the CJ group and one in the MJ group); it was related to infraspinatus strength weakness in IST and ISRT (p < 0.001). Conclusions Infraspinatus-sparing surgical approach for scapular fracture avoids infraspinatus hypotrophy and external-rotation strength weakness. We suggest use of the modified Judet approach for scapular fracture and to restrict the classic Judet approach to only when the surgeon believes that the fracture is not easily reducible with a narrower exposure. Level of evidence Level IV.

Abstract
AIM OF THE STUDY To evaluate total (TSA) and reverse total shoulder arthroplasty (RTSA) using the Constant-Murley score (CMS) and the scapula-weighted (SW) CMS, an integrated outcome measure that takes into account the compensatory movements of the scapula. METHODS Twenty-five consecutive patients, 12 with TSA and 13 with RTSA, underwent kinematic analysis before and after shoulder replacement. Measurements included flexion (FLEX) and abduction (ABD) for the humerus and Protraction-Retraction (PR-RE), Medio-Lateral rotation (ME-LA), and Posterior-Anterior tilting (P-A) for the scapula. They were recorded at baseline (T0) and at six (T1) and 12 months (T2). Reference data were obtained from 31 control shoulders. RESULTS At T1, differences in CMS and SW-CMS were not significant in either group, whereas values at T2 were significantly lower in RTSA patients (p = 0.310 and p = 0.327, respectively). In TSA shoulders, the compensatory scapular movements in FLEX were all reduced from T0 to T2, whereas P-A was increased in ABD. In RTSA patients, the compensatory scapular movements in FLEX showed a general reduction at T1, with an increase in P-A at T2, whereas in ABD, all increased at T1 and decreased at T2 except for P-A, which did not decrease. DISCUSSION The SW-CMS showed that the physiological scapulothoracic motion was not restored in TSA and RTSA patients; it may be used as a reference for the gradual progression of deltoid and scapular muscle rehabilitation. CONCLUSIONS The worse CMS and SW-CMS scores found in RTSA patients at six months may be due to the biomechanics of the reverse prosthesis and to the weakness of deltoid and periscapular muscles.

Abstract
BACKGROUND There are few investigations comparing lateralized and medialized reverse total shoulder arthroplasty (RTSA) in patients with cuff tear arthropathy. This study assessed the outcomes of 2 RTSA designs. METHODS Sixty-eight consecutive cuff tear arthropathy patients (74 shoulders) with a follow-up of at least 24 months received a Grammont or an onlay curved short-stem humeral component, with or without glenoid lateralization; a cementless humeral stem was implanted in >90%. Clinical outcome measures included active range of motion (anterior and lateral elevation, external and internal rotation), pain, and the Constant-Murley score. Radiologic outcomes included radiolucency, condensation lines, cortical thinning, spot weld, loosening and subsidence, and tuberosity resorption for the humeral component and radiolucency, scapular notching, formation of scapular bone spurs, ossifications, and loosening for the glenoid component. RESULTS Both prostheses provided significant differences between preoperative and postoperative scores and showed a similar complication rate. Scapular fractures were found only in the patients who received the curved short-stem implant. Glenoid bone grafting did not significantly affect clinical scores. Both implants provided similar postoperative shoulder mobility, even though the lateralized curved stem was associated with higher delta scores for external rotation (P = .002) and lower rates of scapular notching (P = .0003), glenoid radiolucency (P = .016), and humeral bone remodeling (P = .004 and P = .030 for cortical thinning and spot weld, respectively). CONCLUSIONS Medialized and short-stem lateralized RTSA implants provided similar midterm clinical outcomes and range of motion. The curved short stem was associated with higher delta scores for external rotation and a lower rate of radiographic risk factors.

Abstract
BACKGROUND There remains a paucity of studies examining the conversion of failed hemiarthroplasty (HA) to reverse total shoulder arthroplasty (RTSA). Therefore, the purpose of this study was to examine a large series of revision HA to RTSA. METHODS A population of 157 patients who underwent conversion of a failed HA to a revision RTSA from 2006 through 2014 were included. The mean follow-up was 49 months (range, 24-121 months). The indications for revision surgery included instability with rotator cuff insufficiency (n = 127) and glenoid wear (n = 30); instability and glenoid wear were associated in 38 cases. Eight patients with infection underwent 2-stage reimplantation. RESULTS Patients experienced significant improvements in their preoperative to postoperative pain and shoulder range of motion (P < .0001), with median American Shoulder and Elbow Surgeons and Simple Shoulder Test scores of 60 and 6 points, respectively. There were 11 (7%) repeated revision surgeries, secondary to glenoid component loosening (n = 3), instability (n = 3), humeral component disassembly (n = 2), humeral stem loosening (n = 1), and infection (n = 2). Implant survivorship was 95.5% at 2 years and 93.3% at 5 years. There were 4 reoperations including axillary nerve neurolysis (n = 2), heterotopic ossification removal (n = 1), and hardware removal for rupture of the metal cerclage for an acromial fracture (n = 1). At final follow-up, there were 5 "at-risk" glenoid components. CONCLUSION Patients experience satisfactory pain relief and recovery of reasonable shoulder function after revision RTSA from a failed HA. There was a relatively low revision rate, with glenoid loosening and instability being the most common causes.

Abstract
PURPOSE The reverse shoulder prosthesis (RSP) was developed to relieve pain and improve functional outcomes in patients with glenohumeral arthritis and deficiency of the rotator cuff. Even if clinical and functional outcomes regarding the use of the RSP were reported by literature, data concerning progressive deltoid adaptation to this non-anatomic implant are still missing. The purpose of our study was to correlate clinical and functional outcomes with deltoid fibers activity and muscle fatigability in patients with reverse shoulder prosthesis at 2 years follow-up. METHODS Twenty patients with reverse shoulder prosthesis due to symptomatic deficient or nonfunctional rotator cuff associated with osteoarthritis were referred by Cervesi Hospital Shoulder and Elbow Surgery Unit. Exclusion criteria were: axillary nerve palsy, a nonfunctioning deltoid muscle, diabetes, previous trauma, malignancy. Furthermore patients who received the RSP for revision arthroplasty, proximal humerus fractures were excluded. All the patients underwent clinical and functional evaluation with the support of electromyography measurement focused on deltoid activity. RESULTS RSP surgical treatment in shoulder osteoarthritis confirms his good outcome in terms of pain relief. At 2 years anterior and lateral deltoid electromyographic activity was significantly lower compared with contralateral side (p < 0.001). Posterior deltoid activity was no detectable. Range of motion at 2 years of follow-up decreased in terms of forward flexion (p = 0.045), abduction (p = 0.03) and external rotation (p < 0.001). CONCLUSIONS Our study demonstrates that even if the patients remain pain-free, progressive deterioration of the deltoid activity is unavoidable and may lead to poor functional outcomes overtime.

Abstract
PURPOSE Surgical costs are under scrutiny and surgeons are being held increasingly responsible for cost containment. In some instances, implants are the largest component of total procedure cost, yet previous studies reveal that surgeons' knowledge of implant prices is poor. Our study aims to (1) understand drivers behind implant selection and (2) assess whether educating surgeons about implant costs affects implant selection. METHODS We surveyed 226 orthopedic surgeons across 6 continents. The survey presented 8 clinical cases of upper extremity fractures with history, radiographs, and implant options. Surgeons were randomized to receive either a version with each implant's average selling price ("price-aware" group), or a version without prices ("price-naïve" group). Surgeons selected a surgical implant and ranked factors affecting implant choice. Descriptive statistics and univariate, multivariable, and subgroup analyses were performed. RESULTS For cases offering implants within the same class (eg, volar locking plates), price-awareness reduced implant cost by 9% to 11%. When offered different models of distal radius volar locking plates, 25% of price-naïve surgeons selected the most expensive plate compared with only 7% of price-aware surgeons. For cases offering different classes of implants (eg, plate vs external fixator), there was no difference in implant choice between price-aware and price-naïve surgeons. Familiarity with the implant was the most common reason for choosing an implant in both groups (35% vs 46%). Price-aware surgeons were more likely to rank cost as a factor (29% vs 21%). CONCLUSIONS Price awareness significantly influences surgeons' choice of a specific model within the same implant class. Merely including prices with a list of implants leads surgeons to select less expensive implants. This implies that an untapped opportunity exists to reduce surgical expenditures simply by enhancing surgeons' cost awareness. TYPE OF STUDY/LEVEL OF EVIDENCE Economic/Decision Analyses I.
