RESUMO
Purpose: Various surgical treatments have been described for the treatment of reverse Hill-Sachs lesions (rHSls) sized between 20% and 50% in the case of posterior shoulder dislocation. The aim of this systematic review is to report the clinical and radiological outcomes of subscapularis or lesser tuberosity transfer (McLaughlin and modified procedures) compared to bone or osteochondral autograft or allograft. Methods: A systematic review was performed on five medical databases up to December 2022. The inclusion criteria were clinical studies of all levels of evidence describing clinical or radiological outcomes of either procedure. The assessment of the quality of evidence was performed with the Modified Coleman Score. Results: A total of 14 studies (five prospective and nine retrospective) were included. A total of 153 patients (155 shoulders, 78.4% male) with a mean age of 37.2 (22-79) years were reviewed at an average follow-up of 53.1 (7.1-294) months. No relevant difference was found for the clinical scores, range of motion, complications and redislocation rate between the two treatments. Radiological osteoarthritis (OA) was reported in 11% (10/87) in the McLaughlin group and in 21% (16/73) in the humeral reconstruction group. Conclusions: McLaughlin and anatomic humeral reconstruction lead to similar satisfactory clinical results and a low redislocation rate in the treatment of rHSls. Anatomic humeral reconstruction seems associated with an increased risk of OA progression. Level of Evidence: Level IV.
RESUMO
Stiffness is a clinical disorder that affects the patient's function of the entire upper limb. Many classifications systems have been developed for elbow stiffness based on the plane of motion, severity, aetiology, prognosis or anatomical location. A new classification, the Stiffness types and Influencing Factors Classification System, is proposed as a treatment algorithm to guide the surgical treatment and the preferred operative approach (open or arthroscopic).

INTRODUCTION: Rotator cuff tear (RCT) is a painful, progressive condition resulting from damage to the rotator cuff tendons and is the leading cause of shoulder-related disability. Surgical repair of rotator cuff is an established standard of care (SOC); however, failure of the procedure can occur. In this context, the use of collagen-based bioinductive implant REGENETEN showed long-term improvements in clinical scores. The aim of the study was to assess the cost-effectiveness of REGENETEN combined with SOC (SOC + REGENETEN) compared to SOC alone from both National Healthcare Service (NHS) and societal perspectives in Italy. METHODS: A decision analytic model was developed to estimate the number of tears healed and costs for the two considered treatment strategies over 1 year. Clinical data were retrieved from the literature, and the clinical pathways for the management of patients with RCTs were retrieved from four key opinion leaders in Italy. RESULTS: Over a 1-year time horizon, healed lesions were 90.70% and 72.90% for surgical repair of RCTs with and without REGENETEN, respectively. Considering the NHS perspective, mean costs per patient were 7828 and 4650 for the two strategies, respectively, leading to an incremental cost-effectiveness ratio (ICER) of 17,857 per healed tear. From the societal perspective, the mean costs per patient were 12,659 for SOC and 11,784 for REGENETEN, thus showing savings of 4918 per healed tear when the bioinductive implant is used. The sensitivity analyses confirmed the robustness of the model results. CONCLUSION: In the context of paucity of cost-effectiveness studies, our findings provide additional evidence for clinicians and payers regarding the value of a new treatment option that supports a tailored approach for the management of patients with RCTs.
The rotator cuff refers to a group of four muscles, with tendons connected to the upper arm bone, which act together to allow lifting and rotating the shoulder. A tear of the rotator cuff can affect either a single tendon or multiple tendons. Typical first-line treatment includes conservative therapies, which aim to alleviate pain and reduce functional impairment, but are often ineffective. Persisting disease is usually managed through conventional surgical repair. Recently, REGENETEN, a collagen-based bioinductive implant derived from purified bovine Achilles tendon, positioned over the site of the damaged rotator cuff, achieved successful rotator cuff tendon repair with an increase in healed tears of 17.80% at 1 year compared to conventional surgery. Considering the National Healthcare Service perspective in Italy, the cost needed to achieve one additional healed tear using REGENETEN compared to conventional surgery is 17,857. From the societal perspective, which includes patients' productivity losses from hospital admission to return to work, the use of REGENETEN may be cost-saving compared to conventional surgery. The findings of our study provide evidence for clinicians and payers to support the value of a new treatment option for patients with rotator cuff lesions.

Background: The treatment of shoulder prosthetic joint infections (PJIs) requiring removal of the prosthesis is not well defined. This article aims to systematically review and compare the results of the literature in single-stage and two-stage protocols in the treatment of shoulder PJI. Methods: An in-depth search on PubMed/Scopus/Web of Science databases and cross-referencing search was carried out concerning the articles reporting detailed data on the topic. Results: A total of 486 shoulder PJIs were included: 137 treated with single-stage and 349 with two-stage procedure. A similar distribution between early and not-early infections (19.1% vs 80.9%) was found between the two groups. The overall rate of success in terms of PJI eradication was significantly higher in the single-stage group (95.6% vs 85.7%, p < 0.001). The non-infection-related complications rate was 13.8% in the single-stage group and 37.6% in the two-stage group (p < 0.001), the non-infection-related revision rate was 8% and 18.9%, respectively (p = 0.005). Discussion: The single-phase protocol showed a higher success rate in eradicating the infection and a lower complication rate. However, the low number of patients included, the low quality of the articles, the lack of data on clinical severity and bacteriological virulence suggest caution in conclusions.
RESUMO
The importance of physical activity has been widely demonstrated both in clinics and in sports. One of the new frontier training programs is high-intensity functional training (HIFT). The immediate effects of HIFT on the psychomotor and cognitive performance of well-trained people are still not clear. This paper aims to evaluate the immediate effects induced by HIFT on blood lactate levels, physical performance in terms of body stability and jump ability, and cognitive performance in terms of reaction time. Nineteen well-trained participants were enrolled in the experimental studies and asked to execute six repetitions of a circuit training. Data were gathered both in a pre-training session and after each one of the circuit repetitions. An immediate significant increase with respect to the baseline was observed during the first repetition, with a further increase after the third one. No effects on jump ability were found, whereas a deterioration in body stability was found. Positive immediate effects on cognitive performance in terms of accuracy and speed in task execution were assessed. The findings can be exploited by trainers during coaching to optimize the design of training programs.

BACKGROUND: This study aimed to describe the ARIF (Arthroscopic Reduction Internal Fixation) technique for radial head fractures and to compare the results with ORIF (Open Reduction Internal Fixation) at mean 10 years. METHODS: A total of 32 patients affected by Mason II or III fractures of the radial head who underwent ARIF or ORIF by screws fixation were retrospectively selected and evaluated. A total of 13 patients were treated (40.6%) by ARIF and 19 patients (59.4%) by ORIF. Mean follow-up was 10 years (7-15 years). All patients underwent MEPI and BMRS scores at follow-up, and statistical analysis was performed. RESULTS: No statistical significance was reported in Surgical Time (p = 0.805) or BMRS (p = 0.181) values. Significative improvement was recorded in MEPI score (p = 0.036), and between ARIF (98.07, SD ± 4.34) and ORIF (91.57, SD ± 11.67). The ARIF group showed lower incidence of postoperative complications, especially regarding stiffness (15.4% with ORIF at 21.1%). CONCLUSIONS: The radial head ARIF surgical technique represents a reproducible and safe procedure. A long learning curve is required, but with proper experience, it represents a tool that might be beneficial for patients, as it allows a radial head fracture to be treated with minimal tissue damage, evaluation and treatment of the concomitant lesions, and with no limitation of the positioning of screws.
RESUMO
The surgical management of distal humerus fractures in adults generally consists in open reduction internal fixation (ORIF) or total elbow arthroplasty (TEA). Hemi humeral hemiarthroplasty (EHA) is a treatment option for unreconstructable intra-articular distal humerus fractures. It is a reasonable option in patients over the fifth decade and its potential advantages are to eliminate the complications related to the ulnar component such as wear of the hinge (busching wear) or the aspetic loosening of the ulnar component. The potential disadvantages are the risk of instability with the possibility of a wear and progressive joint osteoarthrosis. The aims of this manuscript are to evaluate the indications in which we used the EHA, analyzing the correct surgical technique and describe the outcomes in medium and long-term follow-ups. Between 2006 and 2019, we performed 51 EHAs at the Hesperia Hospital in Modena and at the Rizzoli Orthopedic Institute. Taking into consideration only the cases of acute fractures, 27 patients (27 elbows) with a minimum follow-up of 12 months were identified. The patient's mean age at the time of surgery was 64 years old (range from 45 to 78 years old) and they were 78% female (21 out of 27). The Latitude Tornier implant was used in all the patients of our group. The mean MEPS was 89.3 points (from 50 to 100 pts) with excellent results in 19 patients, good in 5, one fair and 2 poor;the mean DASH was 12.6 (from 3.3 to 45.8); the mean OES was 42.3 (from 22 to 47). Complications, were found in 12 patients and any patients required a TEA conversion. Distal humerus hemiarthroplasty from our experience is a good option for the surgical management of unrecostructible distal humeral fractures in selected patients. It is important to perform a precise surgical technique; preserve the triceps insertion, preserve or repair the collateral ligaments, fix the condylar bones implant the prosthesis at the correct size, depth and rotation. The majority of the complication that we observed are related to the stiffness and not to the progressive degenerative changes of the articular surface.

BACKGROUND: Temporomandibular disorders (TMDs) are disabling conditions with a negative impact on the quality of life. Their diagnosis is a complex and multi-factorial process that should be conducted by experienced professionals, and most TMDs remain often undetected. Increasing the awareness of un-experienced dentists and supporting the early TMD recognition may help reduce this gap. Artificial intelligence (AI) allowing both to process natural language and to manage large knowledge bases could support the diagnostic process. OBJECTIVE: In this work, we present the experience of an AI-based system for supporting non-expert dentists in early TMD recognition. METHODS: The system was based on commercially available AI services. The prototype development involved a preliminary domain analysis and relevant literature identification, the implementation of the core cognitive computing services, the web interface and preliminary testing. Performance evaluation included a retrospective review of seven available clinical cases, together with the involvement of expert professionals for usability testing. RESULTS: The system comprises one module providing possible diagnoses according to a list of symptoms, and a second one represented by a question and answer tool, based on natural language. We found that, even when using commercial services, the training guided by experts is a key factor and that, despite the generally positive feedback, the application's best target is untrained professionals. CONCLUSION: We provided a preliminary proof of concept of the feasibility of implementing an AI-based system aimed to support non-specialists in the early identification of TMDs, possibly allowing a faster and more frequent referral to second-level medical centres. Our results showed that AI is a useful tool to improve TMD detection by facilitating a primary diagnosis.

CASE: We describe 2 patients with extreme triplanar cubitus varus deformity, treated with step-cut corrective virtually planned osteotomies and performed with custom-made surgical guides. The surgery was simulated on the patients' bone 3D-printed model to verify the effectiveness of the surgical plans. At a medium 21-month follow-up after surgery, in both patients, clinical and radiological results were fully satisfactory, and no complications have been reported. CONCLUSION: The precision of computer-aided surgical planning and custom-made surgical guides allow to perform reproducible and relatively safe surgeries even in extreme deformities where the surgical complexity could discourage attempts at surgical correction.

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.

RATIONALE AND OBJECTIVES: While ultrasound-guided percutaneous irrigation for painful calcific tendinopathy (US-PICT) is the treatment of choice for the rotator cuff, there is a lack of knowledge regarding the treatment of this condition with atypical location. The purpose of our study is to assess if US-PICT can be applied safely and successfully in atypical sites, outside of the rotator cuff. MATERIALS AND METHODS: We retrospectively reviewed the US-PICT performed outside the rotator cuff, in the last 5 years in a single institution. A total of 16 patients have been included in this study. We collected the values of the numerical rating scale (NRS) for pain pre- and post-procedure (7 days and 3-month follow-up). Moreover, we assessed the imaging studies available pre- and post-procedure (ultrasound and plain radiography) to assess complications. RESULTS: In all the 16 patients (10F, 6 M; mean age 50.2; range 24-65-year-old), no complications have been observed during and after the procedures. The mean pain NRS before treatment was 8.7 (range 10-6) and dropped to 1.1 (6-0) after 1 week as well after 3 months 1.1 (6-0). The NRS pain reduction from baseline resulted to be statistically significant after 7 days and 3 months (p < 0.001). CONCLUSION: Our results suggest the safety and efficacy of this procedure, underlining the great potential of US-PICT applied even in different atypical locations.

BACKGROUND: The earliest distal humeral hemiarthroplasty (or elbow hemiarthroplasty [EHA]) implants, which date back to the late 1940s, were performed in patients with severe elbow joint injuries as an alternative to arthrodesis. After some clinical reports and case studies with a short follow-up, published in the 1990s, a new "anatomically convertible" EHA model was introduced in 2005 and became a common surgical option to treat complex elbow fractures and their sequelae. We describe the mid- and long-term outcomes of EHA performed to treat acute intra-articular fractures or their sequelae. METHODS: From 2006 to 2017, 51 patients underwent EHA for acute intra-articular fractures or their sequelae. A total number of 41 patients (80.5% female) with a minimum follow-up of 2 years, 24 with acute lesions and 17 with sequelae, were identified retrospectively. Clinical evaluation was according to the Disabilities of the Arm, Shoulder, and Hand (DASH) score (subjective), and the Oxford Elbow Score (OES) and Mayo Elbow Performance Score (MEPS) (objective). Radiographic follow-up was with standard radiographs. RESULTS: Mean follow-up was 92.2 months (range, 24-151). Mean patient age at surgery was 62.8 years (range, 45-81). The mean MEPS was 87.1 points, with excellent results in 26 cases, good results in 9 cases, fair in 2, and poor results in 4. The mean DASH score was 15.9 and the mean OES was 40.5, with satisfactory results in 30 cases. Twenty patients experienced complications and 2 required revision surgery. DISCUSSION: EHA is a valuable surgical option in selected patients with comminuted distal humeral joint fractures that cannot be reconstructed with stable fixation and in those with malunion of the articular surface of the humerus. EHA offers potential advantages, especially in active elderly patients and in those aged less than 70 years. It is essential to achieve joint stability, restoring medial and lateral ligament function besides the integrity of the coronoid process. An intact olecranon surface without signs of degenerative changes is also critical for EHA success. CONCLUSION: Our mid- and long-term experience with EHA is favorable, with a high proportion of satisfactory results and long survival rates for both lesion types. In selected patients with acute and post-traumatic injuries, EHA is a valuable surgical option.

BACKGROUND: Both nonoperative and operative treatments have been proposed to manage distal biceps brachii tendon avulsions. However, the advantages and disadvantages of these approaches have not been properly quantified. PURPOSE: To summarize the current literature on both nonoperative and operative approaches for distal biceps brachii tendon ruptures and to quantify results and limitations. The advantages and disadvantages of the different surgical strategies were investigated as well. STUDY DESIGN: Systematic review; Level of evidence, 4. METHODS: A systematic literature search was performed in March 2020 using PubMed Central, Web of Science, Cochrane Library, MEDLINE, Iscrctn.com, clinicaltrials.gov, greylit.org, opengrey.eu, and Scopus literature databases. All human studies evaluating the clinical outcome of nonoperative treatment as well as different surgical techniques were included. The influence of the treatment approach was assessed in terms of the Disabilities of the Arm, Shoulder and Hand (DASH) score and the Mayo Elbow Performance Index; extension, flexion, supination, and pronation range of motion (ROM); and flexion and supination strength ratio between the injured and uninjured arms. Risk of bias and quality of evidence were assessed using the Cochrane guidelines. RESULTS: Of 1275 studies, 53 studies (N = 1380 patients) matched the inclusion criteria. The results of the meta-analysis comparing operative versus nonoperative approaches for distal biceps tendon avulsion showed significant differences in favor of surgery in terms of DASH score (P = .02), Mayo Elbow Performance Index (P < .001), flexion strength (94.7% vs 83.0%, respectively; P < .001), and supination strength (89.2% vs 62.6%, respectively; P < .001). The surgical approach presented 10% heterotopic ossifications, 10% transient sensory nerve injuries, 1.6% transient motor nerve injuries, and a 0.1% rate of persistent motorial disorders. Comparison of the different surgical techniques showed similar results for the fixation methods, whereas the single-incision technique led to a better pronation ROM versus the double-incision approach (81.5° vs 76.1°, respectively; P = .01). CONCLUSION: The results of this meta-analysis showed the superiority of surgical management over the nonoperative approach for distal biceps tendon detachment, with superior flexion and supination strength and better patient-reported outcomes. The single-incision surgical approach demonstrated a slightly better pronation ROM compared with the double-incision approach, whereas all fixation methods led to similar outcomes.
RESUMO
BACKGROUND: Locked posterior glenohumeral dislocations with a reverse Hill-Sachs impaction fracture involving less than 30% of the humeral head are most frequently treated with lesser tuberosity transfer into the defect, whereas those involving more than 50% undergo humeral head arthroplasty. Reconstruction of the defect with segmental femoral osteochondral allografts has been proposed to treat patients between these two ranges, but the medium-/long-term outcomes of this joint-preserving procedure are controversial. METHODS: Between 2001 and 2018, 12 consecutive patients with a unilateral locked posterior shoulder dislocation and an impaction fracture from 30 to 50% (mean 31% ± 1.32) of the humeral head were treated with segmental reconstruction of the defect with fresh-frozen humeral head osteochondral allografts. Patients were assessed clinically, radiographically and with computed tomography (CT) at a medium follow-up of 66 ± 50.25 months (range, 24-225). RESULTS: All twelve shoulders presented a slight limitation in anterior elevation (average, 166.6° ± 22.76). The mean active external rotation with the shoulder at 90° of abduction was 82.5° ± 6.61, and that with the arm held in stable adduction was 79.16 ± 18.80. The mean abduction was 156.25° ± 25.09. The mean Constant-Murley score (CS) was 82 ± 15.09 points (range, 40-97 points), and the mean ASES was 94 ± 8.49 points. The mean pre- and postoperatively Western Ontario Shoulder Instability index (WOSI) was 236.5 ± 227.9 and 11.20 ± 10.85, respectively. Development of osteoarthrosis (OA) was minimal. The average allograft resorption rate was 4% ± 2.4. There were no cases of failure (reoperation for any reason) in this series. CONCLUSION: Segmental humeral head reconstruction with humeral head fresh-frozen osteochondral allografts provides good to excellent clinical results with low-grade OA and low allograft resorption in patients with locked posterior shoulder dislocation.

The COVID-19 pandemic has raised concerns about the negative impact of the fear of contagion on people's willingness to seek medical care and the subsequent effects on patients' prognosis. To date, not much is known about the outcomes of acute surgical diseases in this scenario. The aim of this multicenter observational study is to explore the effects of COVID-19 outbreak on the outcomes of patients who underwent surgery for peritonitis. Patients undergoing surgery for secondary peritonitis during the first COVID-19 surge in Italy (March 23-May 4, 2020-COVID period group) were compared with patients who underwent surgery during the same time interval of year 2019 (no-COVID period group). The primary endpoint was the development of postoperative complications. Logistic regression analysis was conducted to identify predictors of complications. Of the 332 patients studied, 149 were in the COVID period group and 183 were in the no-COVID period group. Patients in the COVID period group had an increased frequency of late presentations to the emergency departments (43% vs. 31.1%; P = 0.026) and a higher rate of postoperative complications (35.6% vs. 18%; P < 0.001). The same results were found in the subset analysis of patients with severe peritonitis at surgical exploration. The ASA score, severity of peritonitis, qSOFA score, diagnosis other than appendicitis, and COVID period resulted independent predictors of complications. During the COVID-19 pandemic patients with peritonitis had a higher rate of complicated postoperative courses, weighing on hospital costs and assistance efforts already pressured by the ongoing sanitary crisis.

BACKGROUND: Pain sensitization, defined as an increased responsiveness of nociceptive neurons to normal input, is detected in several musculoskeletal diseases, but there are no systematic reviews or meta-analyses about pain sensitization in shoulder pain. OBJECTIVES: The aim of the study was to document pain sensitization rate and its impact in patients with shoulder pain. MATERIALS AND METHODS: PubMed, Cochrane Library, and Web of Science were searched on January 8, 2020. Level I-IV studies, evaluating pain sensitization in musculoskeletal shoulder disorders through validated methods (questionnaires/algometry) were included. The primary outcome was pain sensitization rate. Secondary outcomes were the pain sensitivity level measured as pressure pain threshold, temporal summation, conditioned pain modulation, and suprathreshold heat pain response. Associated demographic and psychosocial factors were evaluated. RESULTS: The rate of abnormal pressure pain threshold in patients with shoulder pain varied from 29% to 77%. Questionnaires detected pain sensitization in 11% to 24% of patients. This meta-analysis showed no difference in pressure pain threshold and central pain modulation but documented a significant difference in terms of suprathreshold heat pain response, indicating a hypersensitivity state in patients with shoulder pain versus asymptomatic controls. The only factor that was constantly found to correlate with higher sensitivity was a lower postoperative outcome. DISCUSSION: Pain sensitization has a high rate among patients with musculoskeletal shoulder pain, regardless of the specific etiology, and this may lead to worse clinical outcome after treatment of the primary disease. The best way to assess pain sensitization still needs to be identified as the assessment methods results in used high variability in the documented pain sensitization rate.

Multi-fragment fractures are still a challenge: current clinical practice relies on plates and screws. Treatment of fractures of the proximal humerus has the intra-operative risk of articular damage when inserting multiple screws. Distal-varus collapse of the head is a frequent complication in osteoporotic patients. The aim of this biomechanical study was to investigate if an Innovative-cement-technique (the screws are replaced by injection of cement) provides the same or better stability of the reconstructed head compared to the Standard-technique (locking screws). A four-fragment fracture was simulated in twelve pairs of humeri, with removal of part of the cancellous bone to simulate osteoporotic "eggshell" defect. One humerus of each pair was repaired either with a Standard-technique (locking plate, 2 cortical and 6 locking screws), or with the Innovative-cement-technique (injection of a partially-resorbable reinforced bone substitute consisting of PMMA additivated with 26% beta-TCP). Cement injection was performed both in the lab and under fluoroscopic monitoring. The reconstructed specimens were tested to failure with a cyclic force of increasing amplitude. The Innovative-cement-technique withstood a force 3.57 times larger than the contralateral Standard reconstructions before failure started. The maximum force before final collapse for the Innovative-cement-technique was 3.56 times larger than the contralateral Standard-technique. These differences were statistically significant. The Innovative-cement-technique, based on the reinforced bone substitute, demonstrated better biomechanical properties compared to the Standard-technique. These findings, along with the advantage of avoiding the possible complications associated with the locking screws, may help safer and more effective treatment in case of osteoporotic multi-fragment humeral fractures.

INTRODUCTION: Colonic lipomatosis is defined as a poorly circumscribed, non-capsulated fat accumulation in the submucosal layer of the colonic wall. Clinical presentation varies from asymptomatic to acute surgical complications. PRESENTATION OF CASE: We report the case of a 79-year old male who arrived at the Emergency Department complaining of worsening abdominal pain, fever and nausea. A CT scan revealed a periappendicular abscess extended to the ileocecal valve and also the presence of diffuse intramural fatty tissue of the ascending colon. The patient underwent surgery and a right hemicolectomy was performed. The final histological exam confirmed the diagnosis of gangrenous appendicitis with diffuse abscessualization of the ileocecal valve and the presence of submucosal lipomatosis of the ICV extending to the ascending colon. Patient was discharged at 11th-POD. DISCUSSION: Acute appendicitis can represent a complication, although rare, of colonic lipomatosis. The underlying mechanism can be explained by the obstruction of the stool discharge from the appendix caused by the thickened colonic wall due to lipomatosis. Despite the lack of established guidelines on the management of colonic lipomatosis, surgery remains the preferred treatment in case of acute complications. CONCLUSION: Acute appendicitis is a rare clinical manifestation of colonic lipomatosis. As in the case of other acute complications, such as intussesception, surgery remains the preferred therapeutic approach.
RESUMO
Multi-fragmented fractures of the proximal humerus are difficult to treat, especially in the case of osteoporotic bone. Intra-operative risks include cartilage damage when inserting multiple screws. A common post-operative complication is distal-varus collapse of the head. The aim of this study was to investigate if an Innovative technique (reduced number of screws and injection of a beta-TCP additivated partially resorbable cement) provides the same or better stability of the reconstructed head compared to the Standard technique (using more screws). A four-fragment fracture was simulated in six pairs of humeri, with partial removal of the cancellous bone to simulate osteoporotic "eggshell" defect. One humerus of each pair was repaired with a Standard (locking plate, 2 cortical and 6 locking screws), and the other with the Innovative technique (same plate, 2 cortical and only 3 locking screws, plus cement injection). The reconstructed specimens were subjected to a biomechanical test where a cyclic force of increasing amplitude was applied axially until failure. The Innovative reconstructions withstood a force 3.49 times larger than the contralateral Standard reconstructions before failure started. The maximum force before final collapse for the Innovative reconstructions was 4.24 times larger than the contralateral Standard reconstructions. These differences were statistically significant. The Innovative reconstructions, based on fewer screws and beta-TCP additivated acrylic cement, showed positive results, demonstrating better biomechanical properties compared to the Standard reconstructions. These laboratory findings, along with the advantages of a reduced number of screws, may help perform a surgically safer, and more effective procedure in osteoporotic patients.

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.
