ABSTRACT
Background: This study aims to investigate the impact of shoulder surgery on professional gymnasts through a case series, analyzing the mechanisms of injury and the shoulder lesion patterns, and reporting the clinical outcomes and return to sport. Methods: Twenty-nine surgically treated shoulders in twenty-seven professional gymnasts were retrospectively analyzed. Patients were stratified based on predominant symptoms and anatomical lesions in painful or unstable shoulders. Demographic and injury data, pathological findings, surgical procedure information, and data on time and level of return to sport were collected. Results: The average age of participants was 20.2 ± 3.8 years. Acute traumatic onset was reported in 51.8% of cases. Shoulders were categorized as painful in 13 cases and unstable in 16 cases. The most common pathologies were capsulolabral injuries (72%), biceps injuries (48%), and rotator cuff injuries (40%). All of the athletes returned to training within an average of 7.3 months, while the return to competition rate was 56%, achieved in an average of 10.3 months. The sport-specific subjective shoulder value was 84.8% ± 16.6%. Half of the patients who stopped competition reported reasons related to symptom persistence, while the other half reported personal reasons. No significant difference in the return to sport was reported in the cases of painful or unstable shoulder. Conclusions: Professional gymnasts requiring shoulder surgery commonly present multiple and complex lesions. Returning to training was possible in all cases; however, the possibility of persisting symptoms and other personal factors which may compromise the return to competition should be discussed with the athlete to give them insights into the possible outcomes.
ABSTRACT
PURPOSE: The aim of the present systematic review is to collect all the available evidence regarding the clinical and radiological results of revision to reverse shoulder arthroplasty (RSA) of modular anatomic shoulder prostheses (TSA) using a convertible metal-backed glenoid (MBG). METHODS: This study was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement. Studies investigating revision of TSA to RSA utilizing a convertible MBG and reporting clinical and radiological outcomes were identified. RESULTS: A total of five studies on the use of convertible modular glenoid component in the setting of TSA revision to RSA were finally included in the present systematic review. A total of 60 procedures were reported. Mean operative times was 65 min. Intraoperative complications included 3 cases of glenoid loosening. Only one case of dislocation was reported as postoperative complication. At mean follow-up of 32.3 months post-revision, no glenoid loosening was reported, VAS score decreased from 7.7 to 1.5, Constant Score increased from 24.8 to 57.6. CONCLUSIONS: Revision to RSA after failed TSA using a convertible modular glenoid component was associated with a low rate of intraoperative and postoperative complications, low surgical time and led to good results in term of pain relieve and functional outcomes. Given the complexity and risk associated with revision of anatomic shoulder prosthesis having a convertible glenoid may help to simplify the procedure and improve clinical results.
ABSTRACT
Water polo players' shoulders are exposed to repeated overhead and throwing motions as well as direct and indirect traumas. Shoulder injuries account for over half of all injuries sustained by water polo players. This is a monocentric descriptive epidemiological study on the clinical and radiological presentation of a consecutive series of water polo players from January 2002 to September 2022. All patients underwent clinical and physical examinations and an MRI arthrogram. A total of 92 water polo players were included in this study. Fifty-three patients (57.6%) reported at least one previous shoulder instability episode; 100% of patients in this group were diagnosed with a capsulolabral complex lesion, and 88.7% of these players complained of subjective symptoms of shoulder instability (RR: 4.4). A total of 39 out of 92 patients (42.4%) did not report previous shoulder dislocation episodes; the mean age at presentation in this group was significantly higher than the mean age of the patients who experienced previous instability episodes (p < 0.01), and the throwing arm was affected in 79.5% of patients (RR = 1.41).
ABSTRACT
Objectives: We aimed to report radiological and clinical features of single bone intramedullary fixation of the radius in pediatric both bone forearm fractures using straight stainless steel Kirschner (K) wire. Methods: Fifty-eight children (42 boys and 16 girls) referred to our hospital with both bone diaphyseal forearm fractures were operated on by using the single bone rigid K-wire intramedullary fixation and mini-open technique. The mean follow-up time was 8.9 months (6-12). Results: The mean age of the patients was 7.4 years (4-12). More than 2/3 of the fractures were in the right hand. Around 63% of the fractures were in the middle third, 28% in the distal third, and 9% in the proximal third. Moreover, 12% were open type I Gustilo-Anderson fractures. The mean time from injury to surgery was two days (1-4), and the mean length of hospital stay was 2.8 days (2-5). The mean duration of surgery was 24.7 minutes (18-38), and the mean follow-up time was 8.9 months (6-12). All fractures united within 4-16 weeks (mean: 7.62). The cast and implant were removed simultaneously as the radiographic fracture union. There was no serious complication. Superficial infection of the pin track and loosening of the pin occurred in three cases (5%), all controlled by antibiotics and timely removal of the pins. Mild restriction of elbow extension (less than 20 degrees) was observed in three cases, which returned to normal at the last follow-up. Limitation of dorsiflexion of the wrist by more than 20° occurred in two patients (35° and 45°), which reverted to 25° and 25°, respectively, at the last follow-up. Conclusion: In both bone forearm fractures in children, open reduction and internal fixation of only the radius with a stainless steel straight Kirschner wire could be a promising method with good results. This retrograde technique of intramedullary fixation is a simple and cost-effective method with minimal complications and acceptable outcomes in children aged 4-12 years.
ABSTRACT
BACKGROUND: The purpose of this study was to evaluate the impact of software updating on measurements of the glenoid inclination and version, along with humeral head subluxation performed by an automated 3D planning program. The hypothesis was that the software update could significantly modify the values of the glenoid inclination and version, as well as of the humeral head subluxation. METHODS: A comprehensive pool of 76 shoulder computed tomography (CT) scans of patients who underwent total shoulder arthroplasty (TSA) or reverse total shoulder arthroplasty (RTSA) were analyzed with the automated program Blueprint in 2018 and again in 2020 after a software update. RESULTS: A statistically significant difference of 8.1 ± 8.2 and 5.4 ± 7.8 (mean difference of -2.8 ± 5.0, p < 0.001) was indeed reached when comparing the mean glenoid inclination achieved with Blueprint 2018 and Blueprint 2020, respectively. The glenoid version, as well as the humeral head subluxation evaluations, were not significantly different between the two software versions, with mean values being -9.4 ± 8.9 and -9.0 ± 7.4 and 60.1 ± 12.6 and 61.8 ± 12.0, respectively (p = 0.708 and p = 0.115, respectively). In 22% of CT scans, the software update determined a variation of the glenoid inclination of more than 5° or 10°. CONCLUSION: The present study shows the software update of an automated preoperative planning program may significantly modify the values of glenoid inclination. Even though without a significant difference, variations were also found for the glenoid version and humeral head subluxation. Accordingly, these results should further advise surgeons to carefully and critically evaluate data acquired with automated software.
ABSTRACT
PURPOSE: The ideal surgical treatment for anterior shoulder instability is still under debate. In the healthcare setting, both clinical and economic factors must be considered for optimal resource allocation. From the clinical perspective, the Instability Severity Index Score (ISIS) is a helpful and validated tool for surgeons, although a gray area between 4 and 6 exists. In fact, patients with an ISIS < 4 and > 6 can be treated effectively with arthroscopic Bankart repair and open Latarjet, respectively. The purpose of this study was to conduct a cost-effectiveness analysis of arthroscopic Bankart repair versus open Latarjet in patients with an ISIS between 4 and 6. METHODS: A decision-tree model was constructed to simulate the clinical scenario of an anterior shoulder dislocation patient with an ISIS between 4 and 6. Based on previously published literature, outcome probabilities and utility values in the form of Western Ontario Instability Score (WOSI) were assigned to each branch of the tree, alongside institutional cost. The primary outcome assessed was an Incremental cost-effectiveness ratio (ICER) of the two procedures. Eden-Hybbinette was also considered in the model as a salvage procedure for failed Latarjet. A two-way sensitivity analysis was performed to identify the most impactful parameters on the ICER upon their variation within a pre-determined interval. RESULTS: Base case cost was 1245.57 (1220.48-1270.65 ) for arthroscopic Bankart repair, 1623.10 (1580.82-1665.39 ) for open Latarjet and 2.373.95 (1940.81-2807.10 ) for Eden-Hybbinette. Base-case ICER was 9570.23 /WOSI. Sensitivity analysis showed that the most impactful parameters were the utility of arthroscopic Bankart repair, the probability of success of open Latarjet, the probability of undergoing surgery after post-operative recurrence of instability and the utility of Latarjet. Of these, utility of arthroscopic Bankart repair and Latarjet had the most significant impact on the ICER. CONCLUSION: From a hospital perspective, open Latarjet was more cost-effective than arthroscopic Bankart repair in preventing further shoulder instability in patients with an ISIS between 4 and 6. Despite its several limitations, this is the first study to analyze this subgroup of patients from a European hospital setting from both an economic and clinical perspective. This study can help surgeons and administrations in the decision-making process. Further clinical studies are needed to prospectively analyze both aspects to further delineate the best strategy.

PURPOSE: The aim of this multicentric study was to assess which imaging method has the best inter-reader agreement for glenoid bone loss quantification in anterior shoulder instability. A further aim was to calculate the inter-method agreement comparing bilateral CT with unilateral CT and MR arthrography (MRA) with CT measurements. Finally, calculations were carried out to find the least time-consuming method. METHOD: A retrospective evaluation was performed by 9 readers (or pairs of readers) on a consecutive series of 110 patients with MRA and bilateral shoulder CT. Each reader was asked to calculate the glenoid bone loss of all patients using the following methods: best fit circle area on both MRA and CT images, maximum transverse glenoid width on MRA and CT, CT PICO technique, ratio of the maximum glenoid width to height on MRA and CT, and length of flattening of the anterior glenoid curvature on MRA and CT. Using Pearson's correlation coefficient (PCC), the following agreement values were calculated: the inter-reader for each method, the inter-method for MRA with CT quantifications and the inter-method for CT best-fit circle area and CT PICO. Statistical analysis was carried out to compare the time employed by the readers for each method. RESULTS: Inter-reader agreement PCC mean values were the following: 0.70 for MRA and 0.77 for CT using best fit circle diameter, 0.68 for MRA and 0.72 for CT using best fit circle area, 0.75 for CT PICO, 0.64 for MRA and 0.62 for CT anterior straight line and 0.49 for MRA and 0.43 for CT using length-to-width ratio. CT-MRA inter-modality PCC mean values were 0.9 for best fit circle diameter, 0.9 for best fit circle area, 0.62 for anterior straight line and 0.94 for length-to-width methods. PCC mean value comparing unilateral CT with PICO CT methods was 0.8. MRA best fit circle area method was significantly faster than the same method performed on CT (p = 0.031), while no significant difference was seen between CT and MRA for remaining measurements. CONCLUSIONS: CT PICO is the most reliable imaging method, but both CT and MRA can be reliably used to assess glenoid bone loss. Best fit circle area CT and MRA methods are valuable alternative measurement techniques.

INTRODUCTION: The aim of the present study was to evaluate clinical and structural outcomes of patients with a massive irreparable rotator cuff tear treated with arthroscopic superior capsule reconstruction using an acellular porcine dermal xenograft. We hypothesized that this procedure would lead to improvement in clinical and functional results and that structural failure would not influence the final clinical results. MATERIALS AND METHODS: A retrospective analysis on arthroscopic superior capsule reconstruction performed from October 2016 to January 2019 was conducted. The procedure was performed in patients with a massive irreparable posterosuperior rotator cuff tear without a severe glenohumeral arthropathy (Hamada I and II) and complaining a painful pseudoparalysis. Clinical evaluation and MRI study were performed before surgery and after at least 14 months. RESULTS: A comprehensive group of 21 patients with 11 females and 10 males and a mean age of 57 ± 8.5 years underwent arthroscopic superior capsule reconstruction. The graft had a thickness of 1.5 mm in the first 9 cases (43%) since it was used in a single layer. The graft was thereafter doubled for technique evolution in the following 12 cases (57%) achieving a graft thickness of 3 mm. Active ROM significantly improved with a mean increase of active forward flexion from 72.8° ± 7.5° to 120.6° ± 4.5°, active abduction from 68.3° ± 10.2° to 140.2° ± 8.8° and external rotation from 38.2° ± 11.2° to 56.7° ± 6.8° at the last follow-up. The mean Constant score significantly improved from 40.4 ± 6.7 to 73.3 ± 8.2. A graft tear revealed in 52% (11/21) of overall patients was significantly more frequent in single layer graft when compared to double layer (77% vs 33%, p < 0.05). Location and type of graft tear significantly influenced final outcomes. Patients with a healed (graft continuity with bone at medial and lateral insertion) or medial graft tear showed statistically significant better outcomes when compared with patients in which the graft was completely reabsorbed or torn on humeral side (p < 0.05). CONCLUSION: Arthroscopic superior capsule reconstruction using an acellular porcine dermal xenograft may be a viable alternative to treat massive posterosuperior rotator cuff tear in patients with a painful pseudoparalysis without anterosuperior escape. Structural failure may strongly influence final outcomes with significant role played by tear location.

Background: Scapular notching following reverse shoulder arthroplasty (RSA) is caused by both biological and mechanical mechanisms. Some authors postulated that osteolysis that extends over the inferior screw is caused mainly by biological notching. Inverted-bearing RSA (IB-RSA) is characterized by a polyethylene glenosphere and a metallic humeral liner, decreasing the poly debris formation and potentially reducing high grades of notching. This study aims to report the results of IB-RSA on a consecutive series of patients at mid-term follow-up, focusing on the incidence of Sirveaux grade 3 and 4 scapular notching. Methods: A retrospective study on 78 consecutive patients who underwent primary IB-RSA between 2015−2017 was performed. At a 4 years minimum follow-up, 49 patients were evaluated clinically with Constant score (CS), Subjective shoulder value (SSV), American Shoulder and Elbow score (ASES), pain and range of motion, and with an X-ray assessing baseplate position (high, low), implant loosening, and scapular notching. Results: At a mean follow-up of 5.0 ± 0.9, all the clinical parameters improved (p < 0.05). One patient was revised for an infection and was excluded from the evaluation, two patients had an acromial fracture, and one had an axillary neuropraxia. Scapular notching was present in 13 (27%) patients (six grade 1, seven grade 2) and no cases of grade 3 and 4 were observed. Scapular nothing was significantly associated with high glenoid position (p < 0.001) and with lower CS (70 ± 15 vs. 58 ± 20; p = 0.046), SSV (81 ± 14 vs. 68 ± 20; p = 0.027), ASES (86 ± 14 vs. 70 ± 22; p = 0.031), and anterior elevation (148 ± 23 vs. 115 ± 37; p = 0.006). A 44 mm- compared to 40 mm-glenosphere was associate with better CS (63 ± 17 vs. 78 ± 11; p = 0.006), external (23 ± 17 vs. 36 ± 17; p = 0.036), and internal rotation (4.8 ± 2.7 vs. 7.8 ± 2.2; p = 0.011). Conclusions: IB-RSA is a safe and effective procedure for mid-term follow-up. Inverting biomaterials leads to a distinct kind of notching with mainly mechanical features. Scapular notching is associated with a high baseplate position and has a negative influence on range of motion and clinical outcome.
ABSTRACT
BACKGROUND: Shoulder replacement (SR) constitutes the gold standard treatment for severe shoulder diseases, including osteoarthritis, rheumatoid arthritis, complex fractures, avascular necrosis and rotator cuff arthropathy. Although several countries have national registries, there is a lack of epidemiological data on SR. Sharing national statistics and correlating those to other countries could be helpful to compare outcomes and costs internationally. This paper aims to evaluate the trend of hospitalizations for SR (both first implants and revisions of anatomical and reverse prosthesis) in Italy from 2009 to 2019, based on the National Hospital Discharge Reports (S.D.O) provided by the Italian National Health Service (INHS). Moreover, the economic impact on the healthcare system of SR and SR revisions was assessed, providing a statistical prediction for the next ten years. METHODS: The data used in this paper were about patients who underwent Total Shoulder Replacement (TSR), Shoulder Hemiarthroplasty (SH) or Revision of shoulder joint replacement (RSR) from 2009 to 2019 in Italy. Information about patients was anonymous and included age, sex, days of hospitalization, procedures and diagnoses codes. RESULTS: From 2009 to 2019, 73,046 TSR and SH were performed in adult Italian residents, with a cumulative incidence of 13.6 cases per 100,000 adult Italian residents. While, 2,129 revisions of shoulder replacement were performed, with a cumulative incidence of 0.4 cases per 100,000 residents. Overall, females represented the majority of the cases (72.4% of patients who underwent TSR or SH and 59.1% of patients who underwent RSR). From 2009 to 2019, has been assessed an overall cost of 625,638,990 for TSR or SH procedures in Italy. While, an overall cost of 9,855,141 for RSR procedures in Italy was calculated. CONCLUSIONS: The incidence of SR and RSR is expected to increase in the following years, constituting a burden for the healthcare systems. Overall, in Italy, the females represented the majority of patients. Further prospective studies on this topic in different countries can be con-ducted to make comparisons.

Calcific tendinitis of the shoulder (CTS) is one of the pathological conditions that most often affects the shoulder and consists of a calcium deposit that settles within the tendon tissue of the rotator cuff. The scientific literature has long highlighted the impact of anxiety, stress, and depression on CTS. The goal of this case report is to highlight how the emotional state of patients and their neuro-psychomotor behavior induce a state of constant muscular tension which, through the physical phenomenon of piezoelectricity, causes calcium salts to precipitate and form calcifications. Therefore, stress, anxiety, and depression are likely factors underlying the etiopathogenesis of CTS. Consistent with this interpretation, this report presents five cases of CTS treated with three specific neurobiological stimulation treatments using the radioelectric asymmetric conveyer (REAC) technology, which has demonstrated its effectiveness on alterations in postural attitude intended as neuro-psychomotor behavior, anxiety, stress, and depression, as well as on autonomic and metabolic alterations of the tissues at a local level. The results presented suggest that this approach may be useful in the treatment and prevention of CTS.
ABSTRACT
Background Fluctuating asymmetry (FA) is widely defined as the deviation from perfect bilateral symmetry and is considered an epigenetic measure of environmental stress. Rinaldi and Fontani hypothesized that the FA morpho-functional changes originate from an adaptive motor behavior determined by functional alterations in the cerebellum and neural circuits, not caused by a lesion, but induced by environmental stress. They called this phenomenon functional dysmetria (FD). On this premise, they developed the radio electric asymmetric conveyer (REAC) technology, a neuromodulation technology aimed at optimizing the best neuro-psycho-motor strategies in relation to environmental interaction. Aims Previous studies showed that specific REAC neuro postural optimization (NPO) treatment can induce stable FD recovery. This study aimed to verify the duration of the NPO effect in inducing the stable FD recovery over time. Materials and methods Data were retrospectively collected from a population of 29,794 subjects who underwent a specific semiological FD assessment and received the NPO treatment, regardless of the pathology referred. Results The analysis of the data collected by the various participants in the study led us to ascertain the disappearance of FD in 100% of the cases treated, with a stability of the result detected up to 18 years after the single administration of the REAC NPO treatment. Conclusions The REAC NPO neurobiological modulation treatment consisting of a single administration surprisingly maintains a very long efficacy in the correction of FD. This effect can be explained as the long-lasting capacity of the NPO treatment to induce greater functional efficiency of the brain dynamics as proven in previous studies.
ABSTRACT
Facial injuries are often caused by accidental traumas and can be devastating, as their aesthetic outcomes can impact the social relationships and self-esteem of the patient. The reparative processes can be delayed and hindered by the alteration of the endogenous bioelectric activity (EBA) in the damaged tissues, caused by the trauma. In fact, the proper maintenance and generation of EBA is a prerequisite for the cellular health of any tissue and the alteration of EBA determines the inhibition of any cellular repair process, affecting even the cellular differentiation processes. The radio electric asymmetric conveyer (REAC) technology for neurobiological stimulation treatments was designed precisely to restore EBA in both superficial and deep tissues. The two cases of facial trauma presented in this report were treated with the noninvasive treatment of reparative tissue optimization (TO-RPR) applied with REAC technology. The results showed that the REAC TO-RPR treatment can quickly and safely optimize the reparative processes of the tissues, inducing a homogeneous, synchronized, and coordinated recovery, regardless of the type and the aging of the injured tissue and the severity and depth of the lesions.
ABSTRACT
Cells and tissues work like batteries, positively charged by potassium ions and negatively charged by chloride ions. The difference in potential gradient generates an ionic flux, and this, in turn, generates a current that develops endogenous bioelectric fields (EBFs), which are fundamental for all cellular life processes, including reparative phenomena. In damaged tissues, the ionic flow is altered and, consequently, the production of EBFs is altered. This determines an alteration of the reparative processes. In previous studies, the reparative and regenerative treatments of radio electric asymmetric conveyer (REAC) technology have been shown to favor and accelerate the reparative processes of injured tissues, inducing the recovery of ionic flows and EBFs. The purpose of this report is to illustrate the clinical efficacy of REAC treatments for reparative tissue optimization on muscle injuries, even in those with a severity of third degree.
ABSTRACT
PURPOSE: Since the critical shoulder angle (CSA) is considered a risk factor for shoulder pathology and the intra- and inter-rater variabilities in its calculation are not negligible, we developed a deep learning model that calculates it automatically and accurately. METHODS: We used a dataset of 8467 anteroposterior x-ray images of the shoulder annotated with 3 landmarks of interest. A Convolutional Neural Network model coupled with a spatial to numerical transform (DSNT) layer was used to predict the landmark coordinates from which the CSA was calculated. The performances were evaluated by calculating the Euclidean distance between the ground truth coordinates and the predicted ones normalized with respect to the distance between the first and the second points, and the error between the CSA angle measured by a human observer and the predicted one. RESULTS: Regarding the normalized point distances, we obtained a median error of 2.9%, 2.5%, and 2% for the three points among the entire set. Considering CSA calculations, the median errors were 1° (standard deviation 1.2°), 0.88° (standard deviation 0.87°), and 0.99° (standard deviation 1°) for angles below 30°, between 30° and 35°, and above 35°, respectively. DISCUSSION: These results demonstrate that the model has the potential to be used in clinical settings where the replicability is important. The reported standard error of the CSA measurement is greater than 2° that is above the median error of our model, indicating a potential accuracy sufficient to be used in a clinical setting.

PURPOSE: The purpose of this study was to evaluate clinical outcomes and tendon integrity on magnetic resonance imaging (MRI) of chronic posterosuperior rotator cuff tears treated with single-row tensionless repair and subacromial balloon spacer as protection with a minimum follow-up of 2 years. The hypothesis of this study was that this procedure would have acceptable clinical outcomes and tendon-healing rate without increased complications. METHODS: This is a retrospective study of patients with chronic posterosuperior rotator cuff tears repaired with a single-row technique protected with a subacromial balloon device. Patients were followed up for a minimum of 2 years. Clinical outcomes were evaluated with American Shoulder and Elbow Surgeons Standardized Shoulder Assessment Form (ASES) and Numerical Rating Scale (NRS) for pain. MRI study was obtained likewise after at least 2 years to assess tendon-healing rate. Statistical comparison was performed between pre-operative and at least 2-year clinical and imaging follow-up. RESULTS: Thirty-two patients were included in the study with a mean follow-up of 27 ± 7 (range 24-48). The mean age of this cohort was 58 ± 6 (range 41-66) including 15 males and 17 females. The tear size was on average 2.3 cm (range 2-4) and a mean of 2.1 triple-loaded anchors were used (range 2-3). The ASES score significantly increased from a mean of 39 ± 12 points to a mean of 89 ± 12 at the final follow-up (P < 0.001). Similarly, pain significantly reduced from a mean pre-operative NRS of 6.8 ± 1.4 to 0.8 ± 1.5 at the final follow-up (P < 0.001). MRI scans showed that repair occurred in 26 patients (81.3%). Significant higher ASES score was reached at final follow-up in patients with a "healed" (Sugaya I-III) tendon when compared to patients with an evidence of tendon discontinuity on MRI study (Sugaya IV-V), 93 ± 9 and 74 ± 13, respectively (P < 0.001). CONCLUSIONS: Arthroscopic repair of chronic posterosuperior rotator cuff tears using a single-row tensionless repair and subacromial spacer as protection resulted in an 81.3% of tendon integrity at a mean follow-up of 27 months. Clinical outcomes and pain scores significantly improved without severe complications reported after a minimum follow-up of 2 years. LEVEL OF EVIDENCE: III.

The fracture avulsion of the greater tuberosity (GT) represents 2% of all humerus fractures, but the true incidence is likely to be higher, being challenging the initial diagnosis on radiograph. The fracture avulsion of the GT could have different treatments: nondisplaced or minimally displaced fractures are treated conservatively, whereas for displaced or comminuted fractures surgical treatment is preferred. The most important finding of this study is the employment of an all-arthroscopic transosseous augmented technique for the treatment of a displaced humeral GT fracture avulsion. This technique shows all the advantages of the transosseous fixation and arthroscopic approach.
