RoboticAssisted (RATS) versus Video-Assisted (VATS) lobectomy: A monocentric prospective randomized trial. EUROPEAN JOURNAL OF SURGICAL ONCOLOGY 2023; 49:107256. [PMID: 37925829 DOI: 10.1016/j.ejso.2023.107256] [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: 07/17/2023] [Revised: 09/26/2023] [Accepted: 10/29/2023] [Indexed: 11/07/2023]
Abstract
INTRODUCTION The study aim is to compare Video-Assisted (VATS) and Robotic-Assisted (RATS) lobectomy in the effort to identify advantages and limits of robotic procedures considering the high costs and specific surgeon training. MATERIALS AND METHODS This is a monocentric prospective randomized trial in which patients suitable for mini-invasive lobectomy were randomized 1:2 in two groups: Group A, RATS (25 patients), and Group B, VATS (50 patients). The two groups were compared in terms of perioperative and postoperative results with a mean follow up of 37.9 (±10.9) months. RESULTS We observed a significant reduction of pleural effusion on day 1 (140 ml vs 214, p = 0.003) and day 2 (186 vs 321, p = 0.001) for group A. The Visual Analogue Scale (VAS) showed significantly lower pain in the 1st p.o. day in group A (0,92 vs 1,17, p = 0,005). Surgery time in Group B was significantly lower (160 min vs 180, p = 0.036), but had a higher onset of atrial fibrillation and other cardiac arrhythmias (0/25 vs 9/50, p = 0.038). The OS and DFS were similar between the two groups (95.5 % vs 93.1 %, and 95.5 % vs 89.7 %, respectively). Furthermore, no statistical difference in the evaluation of quality of life during follow-up was found. CONCLUSIONS The RATS approach, although burdened by higher surgical costs, constitutes a valid alternative to VATS; as it determines a lower inflammatory insult, with a consequent reduction in pleural effusion, less post-operative pain and cardiological comorbidities for the patient, it can potentially determine the shortening in hospitalization. In addition, RATS allows accurate lymph node dissection, which permit to reach results that are not inferior to VATS in terms of long-term outcomes.

Abstract
To evaluate incidence of and risk factors for respiratory bacterial colonization and infections within 30 days from lung transplantation (LT). We retrospectively analyzed microbiological and clinical data from 94 patients transplanted for indications other than cystic fibrosis, focusing on the occurrence of bacterial respiratory colonization or infection during 1 month of follow-up after LT. Thirty-three percent of patients developed lower respiratory bacterial colonization. Bilateral LT and chronic heart diseases were independently associated to a higher risk of overall bacterial colonization. Peptic diseases conferred a higher risk of multi-drug resistant (MDR) colonization, while longer duration of aerosol prophylaxis was associated with a lower risk. Overall, 35% of lung recipients developed bacterial pneumonia. COPD (when compared to idiopathic pulmonary fibrosis, IPF) and higher BMI were associated to a lower risk of bacterial infection. A higher risk of MDR infection was observed in IPF and in patients with pre-transplant colonization and infections. The risk of post-LT respiratory infections could be stratified by considering several factors (indication for LT, type of LT, presence of certain comorbidities, and microbiologic assessment before LT). A wider use of early nebulized therapies could be useful to prevent MDR colonization, thus potentially lowering infectious risk.

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.

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.

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
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 Scapular dyskinesis is a recognized cause of shoulder pain in the throwing shoulder of baseball pitchers and athletes who participate in overhead sports. Past studies have assessed scapular kinematics using electromagnetic tracking devices and have shown a correlation between posterior shoulder tightness and forward scapular posture. The purpose of our study is to evaluate the scapular kinematics, before and after a 4-week posterior stretching protocol in asymptomatic pitchers. METHOD Eleven asymptomatic collegiate baseball pitchers were involved in the study and divided into group A (6 pitchers) underwent 4 weeks of a regimented therapy protocol and group B (5 pitchers) did not receive any treatment. Each pitcher was tested on two separate days: at the first day of the study (S1) and after 4 weeks (S2). RESULTS The results demonstrate that there are statistically significant differences in the kinematics of several athletes from the "treated group" (group A) between S1 and S2. It is also important to notice that variations in group A occurred in both flexextension and ab/adduction movements, strengthening the conclusion that the variation was real. CONCLUSION The results of the study can indicate that, in order to prevent the pathologic cascade linked to these sports activities, this physical training protocol might become integral part of the normal daily exercises of baseball pitchers and overhead athletes. Level of evidence II.

Abstract
PURPOSE Stable fixation of distal humerus fracture fragments is necessary for adequate healing and maintenance of reduction. The purpose of this study was to measure the reliability and accuracy of interpretation of postoperative radiographs to predict which implants will loosen or break after operative treatment of bicolumnar distal humerus fractures. We also addressed agreement among surgeons regarding which fracture fixation will loosen or break and the influence of years in independent practice, location of practice, and so forth. METHODS A total of 232 orthopedic residents and surgeons from around the world evaluated 24 anteroposterior and lateral radiographs of distal humerus fractures on a Web-based platform to predict which implants would loosen or break. Agreement among observers was measured using the multi-rater kappa measure. RESULTS The sensitivity of prediction of failure of fixation of distal humerus fracture on radiographs was 63%, specificity was 53%, positive predictive value was 36%, the negative predictive value was 78%, and accuracy was 56%. There was fair interobserver agreement (κ = 0.27) regarding predictions of failure of fixation of distal humerus fracture on radiographs. Interobserver variability did not change when assessed for the various subgroups. CONCLUSIONS When experienced and skilled surgeons perform fixation of type C distal humerus fracture, the immediate postoperative radiograph is not predictive of fixation failure. Reoperation based on the probability of failure might not be advisable. TYPE OF STUDY/LEVEL OF EVIDENCE Diagnostic III.

Abstract
QUESTIONS/PURPOSES Although the posterior labral tears of the shoulder are known for their disabling clinical course, especially in overhead athletes, no clinical test used in isolation can diagnose it accurately in the preoperative period. We wanted to: (1) introduce "Porcellini test" with its radiological verification furnishing the anatomical basis of its mechanism; (2) determine its accuracy; and (3) compare its accuracy with that of the other established tests for diagnosing posterior labral tears of the shoulder. METHODS To determine the anatomical basis, we initially performed radiological verification of our test. Then, we evaluated its accuracy in a retrospective case-controlled study on 310 consecutive patients who underwent shoulder arthroscopic procedures at our hospital between January 2013 and December 2013. All patients were examined preoperatively for Porcellini test, and the presence of posterior labral tear was confirmed on arthroscopy. Later, in a cohort study on 91 consecutive patients who underwent shoulder arthroscopic procedures, we compared its accuracy with O'Brien's test, the Kim test, the Jerk test, and the Load and Shift test. The accuracy was interpreted in terms of sensitivity, specificity, and predictive values. RESULTS The radiological verification conferred the anatomical basis for the mechanism of the Porcellini test. This new test showed high accuracy for posterior labral tears with sensitivity of 100 %, specificity of 99.3 %, the positive and negative predictive values of 92.6 and 100 %, respectively. Also, it had superior accuracy results than every other test. The interexaminer reliability for all test results was found to be >0.80. CONCLUSIONS We propose "Porcellini test" as a simple, accurate, reproducible, and reliable test for the preoperative diagnosis of posterior labral tears of shoulder.

Abstract
AIMS We evaluated clinical and radiographic outcomes of total shoulder arthroplasty (TSA) using the second-generation Trabecular Metal (TM) Glenoid component. The first generation component was withdrawn in 2005 after a series of failures were reported. Between 2009 and 2012, 40 consecutive patients with unilateral TSA using the second-generation component were enrolled in this clinical study. The mean age of the patients was 63.8 years (40 to 75) and the mean follow-up was 38 months (24 to 42). METHODS Patients were evaluated using the Constant score (CS), the American Shoulder and Elbow Surgeons (ASES) score and routine radiographs. RESULTS Significant differences were found between the pre- and post-operative CS (p = 0.003), ASES (p = 0.009) scores and CS subscores of pain (p < 0.001), strength (p < 0.001) and mobility items (p < 0.05). No glenoid or humeral components migrated. Posterior thinning of the keel and slight wear at the polyethylene-TM interface was observed in one patient but was asymptomatic. Radiolucent lines were found around three humeral (< 1.5 mm) and two glenoid components (< 1 mm) and all were asymptomatic. DISCUSSION TSA with the second-generation TM Glenoid component results in satisfactory to excellent clinical performance, function, and subjective satisfaction at a mean follow-up of about three years. Radiographic changes were few and did not affect the outcome. TAKE HOME MESSAGE This paper highlights that the second generation Trabecular Metal Glenoid has better outcomes than those reported with the first-generation component.

Abstract
BACKGROUND The radiographic appearance of osteochondritis dissecans (OCD) of the humeral capitellum varies according to the stage of the lesion. It is important to evaluate the stage of OCD lesion carefully to guide treatment. We compared the interobserver reliability of currently used classification systems for OCD of the humeral capitellum to identify the most reliable classification system. METHODS Thirty-two musculoskeletal radiologists and orthopaedic surgeons specialized in elbow surgery from several countries evaluated anteroposterior and lateral radiographs and corresponding computed tomography (CT) scans of 22 patients to classify the stage of OCD of the humeral capitellum according to the classification systems developed by (1) Minami, (2) Berndt and Harty, (3) Ferkel and Sgaglione, and (4) Anderson on a Web-based study platform including a Digital Imaging and Communications in Medicine viewer. Magnetic resonance imaging was not evaluated as part of this study. We measured agreement among observers using the Siegel and Castellan multirater κ. RESULTS All OCD classification systems, except for Berndt and Harty, which had poor agreement among observers (κ = 0.20), had fair interobserver agreement: κ was 0.27 for the Minami, 0.23 for Anderson, and 0.22 for Ferkel and Sgaglione classifications. The Minami Classification was significantly more reliable than the other classifications (P < .001). CONCLUSIONS The Minami Classification was the most reliable for classifying different stages of OCD of the humeral capitellum. However, it is unclear whether radiographic evidence of OCD of the humeral capitellum, as categorized by the Minami Classification, guides treatment in clinical practice as a result of this fair agreement.

Abstract
BACKGROUND The cuff tendon that is most prone to full-thickness rotator cuff tears is the supraspinatus (SSP). Arthroscopic SSP repair ensures good to satisfactory mid- to long-term clinical outcomes. However, the intense postoperative pain reduces rehabilitation compliance and is cause of patient dissatisfaction. Many natural compounds act by inhibiting inflammatory pathways in a similar way to anti-inflammatory drugs MATERIALS AND METHODS This was a prospective randomized trial designed to assess the analgesic effect of a dietary supplement (DS) containing Boswellia serrata and Curcuma longa in a population of subjects with full-thickness SSP tendon tear treated by arthroscopy. Three weeks before surgery, patients were randomized to receive Tendisulfur(®) (group T) or a placebo (group P) for 2 months. The primary outcome measure was subjective VAS pain. Secondary outcomes measures were Constant-Murley score simple shoulder test, and patient global assessment (PGA) scores. Patients were assessed immediately at baseline and subsequently at 1, 2, 4, 6, 8, 12, and 24 weeks. RESULTS Stratification of pain scores and subscores demonstrated significantly lower overall pain scores in group T versus group P at 1 week (p = 0.0477), and lower but not significantly different scores on week 2 (p = 0.0988); at subsequent time points, differences were not significant (p > 0.05). PGA scores were good in all subjects. CONCLUSIONS In conclusion, this study provides objective data on the effect of a DS containing natural substances, added to standard analgesics, on postoperative RC pain. DS alleviated short and partially mid-term pain, while long-term pain was unchanged. This limitation can probably be addressed by a dosage increase over the first 4 weeks and by extending treatment by 1 or 2 months.

Abstract
PURPOSE The purpose of this study was to look at the functional outcomes of arthroscopic repair of anterosuperior rotator cuff tears. METHODS Sixty-one patients who underwent arthroscopic repair of anterosuperior cuff tears were retrospectively reviewed. At a minimum 6 months of follow-up, shoulder functional outcome scores including the Constant score (CS), simple shoulder test (SST) and visual analogic scale (VAS) were collected. Strength recovery for supraspinatus and subscapularis was investigated. RESULTS All patients (mean age 59 ± 7) were available at a mean follow-up of 18 ± 7 months. The average CS improved from 30.8 ± 10.2 preoperatively to 76.5 ± 12.0 postoperatively, average SST from 2.6 ± 2.0 to 8.8 ± 2.9 and average VAS pain scale from 3.8 ± 1 to 0.5 ± 0.5 (p < 0.0001). Strength at belly-press and Jobe tests significantly improved (p < 0.0001). All patients with the exception of one were satisfied with the intervention. CONCLUSIONS Arthroscopic repair of anterosuperior rotator cuff tears provides a significant improvement in pain relief and shoulder function. Strength recovery is demonstrated in medium correlation with tendon healing.

Abstract
BACKGROUND Elbow osteoarthritis (OA) is a degenerative condition which in the advanced stage can severely impair joint mobility. Conservative treatment remains the first choice; surgery should be considered in case of failure in patients prepared to adhere to a demanding rehabilitation protocol. We assess the effectiveness of arthroscopic joint debridement and capsular release in a series of patients with primary and post-traumatic elbow arthritis. MATERIALS AND METHODS Forty-eight subjects (40 males, eight females; mean age 48 years) with a preoperative diagnosis of primary (19, 40 %) or post-traumatic OA (29, 60 %) were evaluated at a mean follow-up of 44 months. Outcome measures were active range of motion (ROM), pain score, Oxford elbow score (OES), and Mayo elbow performance score (MEPS). OA severity was graded into three classes (I-III) based on X-ray findings. Statistical significance was set at 5 %. RESULTS At the final follow-up evaluation, active flexion/extension increased significantly (p < 0.01); pronation and supination improved, but the difference was not significant (p > 0.05). The pain score improved from 7.2 to 4.3 (p < 0.01). Both OES and MEPS improved significantly (p < 0.001). Patients with post-traumatic OA had better ROM (p = 0.0391) and clinical scores (OES, p = 0.011; MEPS, p = 0.010). ROM and clinical scores were lower but not significantly so in class II than in class I patients. A smooth coronoid and olecranon fossa was found in 38 (79 %) patients and a preserved ulnotrochlear joint space in 40 (80 %). CONCLUSIONS Elbow OA has become more common as a result of earlier diagnosis and an increased number of acute injuries involving the joint. Arthroscopy is an effective technique to treat OA which provides the best results with the correct indications. Prospective studies are needed to help develop guidelines enabling selection of the best treatment option.

Abstract
INTRODUCTION Total reverse shoulder arthroplasty is becoming more and more the standard therapeutic practice for glenohumeral arthropathy with massive lesions of the rotator cuff. The biomechanical principle of this prosthesis is represented by the reversion of the normal anatomy of the shoulder joint. This non-anatomical prosthesis leads to a medialization of the rotation centre of the glenohumeral joint and also to a distalization of the humeral head. All that causes a deltoid tension increasing so allowing a larger abduction of the arm. Main complications of the reverse shoulder prosthesis are due to the joint instability, the scapular notching and the wear of the polyethylene insert. PURPOSE The main goal of the present work is to study the effect of the positioning of the humeral component on the intrinsic stability of the reverse shoulder prosthesis. In particular, through finite element method simulations, the variation of the stability ratio of the shoulder joint has been calculated for both vertical and horizontal dislocating loads depending on the humeral stem version angle. Moreover, in order to estimate the wear of the polyethylene cup, some analyses have been developed to calculate the pressures on the polyethylene insert. RESULTS The obtained results demonstrate the dislocation of a shoulder prosthesis and the wear of the polyethylene insert can be prevented or limited by conveniently varying the version angle of the humeral component.

Abstract
BACKGROUND The transosseous approach has been well known for a long time as a valid repair approach. Over time, various criticisms have been raised over this technique principally classifiable in two main categories: technical difficulty and related reproducibility in an arthroscopic environment, and repair stability (in the suture-bone contact area). About cyclic performance, several authors have conceived test setups with the aim of simulating a real environment in dynamic load conditions. The aim of this study was to monitor gap formation in a cyclic test setup. METHODS The performance (measured as gap formation) has been monitored as a function of bone density to verify the effect of the latter. The test blocks have been shaped using sawbones® test bricks (Malmo, Sweden) of different densities, and the following values have been tested: 10, 15, 20, 30 and 40pcf. FINDINGS The comparison has been made between the two groups: traditional transosseous and new approach with an interposed device. Regarding the traditional transosseous approach in a 10-pcf environment, not even the first loading cycle was completed, the whole bone bridge was destroyed in the first loading ramp and no further loading capability was present in the repair. By increasing the block density, the surface damage in the suture-block contact decreased. INTERPRETATION With this work, it has been demonstrated how the traditional transosseous approach is strongly influenced by the bone quality up to the point where, in certain conditions, a safe and reliable repair is not guaranteed.

Abstract
BACKGROUND Snapping scapula is characterized by crepitus between the scapula and the chest wall due to abnormal tissue at this site. Surgical treatment, when needed, may be either open or arthroscopic. The aim of this study was to evaluate prospectively the clinical outcomes of arthroscopic decompression in ten subjects with symptomatic snapping scapula. PATIENTS AND METHODS Ten subjects, five men and five women, mean age 24 years, were treated by arthroscopy after unsuccessful conservative management for 6 months. Clinical outcomes were evaluated with the Western Ontario Rotator Cuff (WORC) index, Constant-Murley score (CS), and simple shoulder test (SST). Follow-up was at 3 and 6 months; the final evaluation was conducted at a mean interval of 24 months. The final and preoperative X-rays were compared. RESULTS The WORC index increased significantly at 3 (p < 0.05), 6 (p < 0.01), and 24 months (p < 0.01). Similar outcomes were found for the CS at all 3 follow-up points (3 months, p < 0.05; 6 months, p < 0.01; 24 months, p < 0.01). Mean "yes" responses on the SST were 9.8 ± 1.4 at 3 months (p < 0.05), 10.2 ± 1.2 at 6 months (p < 0.01), and 10.6 ± 1.2 at 24 months (p < 0.01). X-ray examination depicted flattening of the anterior surface of the superior-medial angle of the scapula in the five patients who had had bone resection, whereas no significant difference with preoperative imaging was detected in the five patients who were managed by bursectomy and debridement alone. CONCLUSIONS Arthroscopy is a feasible and minimally invasive treatment for painful snapping scapula syndrome. Comparative clinical trials are needed to collect conclusive data to state that it is the most suitable treatment for this condition.

Abstract
PURPOSE Throwing a baseball requires a coordinated sequence of scapula and humerus movements also called scapulo-humeral rhythm (SHR). Fatigue associated with repetitive throwing can lead to scapular dyskinesia, a recognized cause of shoulder disability in pitchers and overhead athletes. We introduce a novel device, the Xbus Kit, which can objectively assess scapular biomechanics and the effect of pitching on SHR. METHODS SHR was studied using the Xbus Kit (Xsens Technologies B.V., NL). Thirteen collegiate baseball pitchers (aged 20 ± 2.6) were studied, evaluating SHR in forward elevation and abduction in three sessions: before throwing (S1), after 60 pitches (S2) and 24 h after a pitching session (S3). RESULTS SHR changes were found in 85 % of pitchers (11 cases), and no changes were observed in 2 cases (15 %). We were able to subdivide pitchers into four groups, based on their response to pitching. CONCLUSION Repetitive movement of pitching leads to SHR changes and sometimes, incomplete restoration of normal shoulder biomechanics.

Abstract
PURPOSE Humeral resurfacing is a treatment option to conventional shoulder arthroplasty, conferring the advantages to preserve the bone stock and the normal joint geometry. Aim of the current study was to report clinical and radiographic mid-term outcomes in a population of 60 patients, aged 50 years or younger, who underwent shoulder resurfacing in osteoarthritis. METHODS The mean age was 48 ± 8.4, 36 were male and 24 female, dominant arm in 43 cases. Glenoid arthritis was treated in 36 cases (60 %) using a meniscus allograft in 22 cases, biologic patch in 4 cases and microfractures in 10 cases. Clinical and radiographic assessment was performed with Constant-Murley score and standard X-ray. RESULTS At an average follow-up of 44 months, the mean values of the constant score increased of 30 points (p < 0.05), the pain decreased of 4.56 points (p < 0.05) and the Simple Shoulder Test increased of 4.3 points (p < 0.05). We found lower scores (p > 0.05) in 9 patients (15 %) treated for glenoid arthritis using homologous meniscus (7 cases) and biologic patch (2 cases). A significant narrowing of joint space (5.92 mm postoperative versus 1.65 mm at 37 months) (p < 0.05) was found in the 22 cases treated with meniscus interposition. In 4 cases with type A2 preoperative glenoid morphology and in 9 cases type B1, we registered significantly lower scores compared with the overall study population (p < 0.01). Five unsatisfied patients (7 %), underwent to meniscus removal and glenoid reaming in 3 cases and conversion in total shoulder arthroplasty in 2 cases. CONCLUSIONS Resurfacing arthroplasty is an effective device in young patients with advanced glenohumeral arthropathy; however, the high rate of postoperative glenoid erosion and the failure of biologic allograft lead us to consider glenoid replacement as the best option to improve clinical outcomes.
