Rotator Cuff Repair in Pediatric and Adolescent Athletes: Indications and Outcomes.

Rotator cuff (RC) tears in pediatric and adolescent athletes are rare events. In these patients, RC tears are more likely to be traumatic or related to overuse among overhead. Repeated movements of abduction and external rotation are frequent mechanisms of injury. The supraspinatus is the most commonly involved tendon and the articular-sided tears are more common than the bursal side. Magnetic resonance imaging is considered the gold standard for diagnosing RC tears. Conservative treatment, arthroscopic, and open repair are all effective treatment methods depending on the type of injury. The risk of growth plate injury in these patients should be always considered when planning surgical interventions. Return to sport for competitive-level throwing athletes represents the greatest challenge in the treatment of these injuries.

The Italian Unitary Society of Colon-proctology (SIUCP: Società Italiana Unitaria di Colonproctologia) guidelines for the management of anal fissure.

INTRODUCTION: The aim of these evidence-based guidelines is to present a consensus position from members of the Italian Unitary Society of Colon-Proctology (SIUCP: Società Italiana Unitaria di Colon-Proctologia) on the diagnosis and management of anal fissure, with the purpose to guide every physician in the choice of the best treatment option, according with the available literature. METHODS: A panel of experts was designed and charged by the Board of the SIUCP to develop key-questions on the main topics covering the management of anal fissure and to performe an accurate search on each topic in different databanks, in order to provide evidence-based answers to the questions and to summarize them in statements. All the clinical questions were discussed by the expert panel in different rounds through the Delphi approach and, for each statement, a consensus among the experts was reached. The questions were created according to the PICO criteria, and the statements developed adopting the GRADE methodology. CONCLUSIONS: In patients with acute anal fissure the medical therapy with dietary and behavioral norms is indicated. In the chronic phase of disease, the conservative treatment with topical 0.3% nifedipine plus 1.5% lidocaine or nitrates may represent the first-line therapy, eventually associated with ointments with film-forming, anti-inflammatory and healing properties such as Propionibacterium extract gel. In case of first-line treatment failure, the surgical strategy (internal sphincterotomy or fissurectomy with flap), may be guided by the clinical findings, eventually supported by endoanal ultrasound and anal manometry.

Impact of Preoperative Three-Dimensional Endoanal Ultrasound on the Surgical Outcome of Primary Fistula in Ano. A Multi-Center Observational Study of 253 Patients.

PURPOSE: To evaluate the impact of preoperative three-dimensional endoanal ultrasound (3D-EAUS) on the clinical outcome of anal fistula surgery. METHODS: The research consisted of multi-center retrospective case-control study including 253 consecutive adult patients undergoing surgery for confirmed or suspected primary fistula in ano who had undergone preoperative 3D-EAUS evaluation between January 2011 and January 2021. Main outcome measures were the concordance (K value) between ultrasound results and surgery in the identification of fistulas internal openings, primary tracts and secondary extensions and the 6 and 12 months success rate in patients with concordant and discordant findings. RESULTS: A good agreement in the identification of the main fistulas characteristics between ultrasound results and operative findings was found. A significant difference (P < .0001; Fisher's exact test) in the success rate was found between patients with concordant and discordant ultrasound results and operative findings in identification or location of internal opening. Particularly, all the 11 (4.8%) patients with discordant results experimented a failure of the surgical procedure at 6 months follow-up. At re-operation, the shift from discordant to concordant results was associated with an 81.8% 12 months success-rate. CONCLUSION: The three-dimensional endoanal ultrasound preoperative evaluation may have a relevant impact on the outcome of a defined group of patients undergoing surgery for anal fistula, since the careful evaluation of ultrasound results could simplify the internal orifice intra-operative detection and improve the success rate.

The management of the long head of the biceps in rotator cuff repair: A comparative study of high vs. subpectoral tenodesis.

BACKGROUND: Tenodesis of the long head of the biceps (LHB) is commonly undertaken during arthroscopic rotator cuff repair. We assessed the clinical and structural outcomes after high arthroscopic tenodesis (HAT) or mini-open subpectoral tenodesis (ST). We hypothesized that the clinical and structural results after HAT and ST are similar. METHODS: We included 40 patients with rotator cuff tear and LHB tendinopathy. Twenty patients (7 women and 13 men; mean age: 57.9 years; range: 56-63 years) were treated using HAT, and 20 patients (8 women and 12 men; mean age: 58.5 years; range: 55-64 years) were treated using ST. Functional evaluation was performed preoperatively and at 6 weeks, 6 months, and 1 year after surgery, using the Constant Murley Score and Simple Shoulder Test scores; the LHB was evaluated using the LHB score. A Visual Analogue Scale was administered to all patients preoperatively and 2 days after surgery. RESULTS: The postoperative total and pain subscale's Constant scores were significantly higher in the ST group. Moreover, 2 LHB score values were significantly different between the groups. The postoperative LHB total score in the ST and HAT groups averaged 86.9 ± 4.1 (mean ± SD) points and 73.3 ± 6.4 points, respectively. The Pain/Cramps subscale in the ST and HAT groups averaged 47.1 ± 5.9 and 33.2 ± 4.6 points, respectively. The 2 groups showed no difference in Visual Analogue Scale values (5.5 in the HAT group; 5.8 in the ST group) postoperatively. One patient in the HAT group reported a secondary onset of Popeye deformity. CONCLUSION: Both high arthroscopic and mini-open ST of the LHB tendon produced reliably good functional results, but the ST group was associated with better postoperative clinical outcomes.

Return to Sport After Total Shoulder Arthroplasty and Hemiarthroplasty: A Systematic Review.

PURPOSE: One of the most frequent concerns of the increasing number of patients undergoing shoulder arthroplasty is the possibility to resume sport after surgery. This systematic review determined the rate of return to sport after total shoulder arthroplasty (TSA) and hemiarthroplasty (HA). MATERIALS AND METHODS: The PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines were followed to perform this systematic review. A systematic electronic search was performed using the PubMed (MEDLINE), EMBASE, and Cochrane Library databases. All the studies analyzing the rates of reverse shoulder arthroplasties were pooled; data were extracted and statistically analyzed. Only studies with at least 10 adult patients recruited were considered. All studies had to relate return to sport after TSA or HA. RESULTS: A total of 76 studies were included for a total of 694 patients. The mean age and average follow-up were, respectively, 64.5 years (range: 24 to 92 y) and 4.5 years (range: 0.5 to 12 y). The mean rate of return to sport ranged from 49.3% to 96.4%. The mean time to resume sports was 8.1 months. The overall rate of return to sport after the procedures, according to a random effect model, was 83%. The mean level of sports at the time of the survey was worsened in 9.4% (±2.82%), improved or reported from good to excellent in 55.6% (±13.6%), and did not change in 40% (±1.4) of patients. CONCLUSIONS: On the basis of current available data, return to sports after TSA and HA is possible and is highly frequent. The subjective level of practice does not change or improve in most patients. More studies and better designed trials are needed to enrich the evidence on specific sport recovery after the procedure.

Return to sport after reverse total shoulder arthroplasty is highly frequent: a systematic review.

IMPORTANCE: One of the most frequent concerns of the increasing number of patients undergoing shoulder arthroplasty is the possibility to resume sport after surgery. OBJECTIVE: The aim of this systematic review was to determine the rate of return to sport after reverse total shoulder arthroplasty (RSA) and the subjective level of performance. EVIDENCE REVIEW: The Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines were followed to perform this systematic review. A systematic electronic search was performed using the PubMed (MEDLINE), Embase and Cochrane Library databases. All the studies analysing the rates were pooled; data were extracted and statistically analysed. The eligibility criteria were studies with at least 20 adult patients recruited. All studies had to relate return to sports after RSA. FINDINGS: A total of six studies were included for a total of 457 patients. Mean age and average follow-up were, respectively, 74.7 years (range 33-88 years) and 3.6 years (range 1-9.4 years). The mean rate of return to sport ranged from 60% to 93%. The mean time for resuming sports was 5.3 months. The overall rate of return to sport after reverse shoulder arthroplasty was 79%. The mean level of sports at the time of the survey was worsened in 7.9%, improved in 39.6% and had no change in 55.2% of the cases. CONCLUSIONS AND RELEVANCE: Based on the current available data, return to sports after reverse shoulder arthroplasty is possible and highly frequent. The subjective level of practice undergoes no change or improves in most of the cases. More studies and better-designed trials are needed in order to enrich the evidence on specific sports recovery after the procedure. LEVEL OF EVIDENCE: IV.

Fatal Clostridium Infection in a Leg-Amputated Patient after Unsuccessful Knee Arthroplasty.

Prosthetic joint infection (PJI) is a possible complication occurring after prosthesis implantation. We describe the case of a patient with early postoperative multidrug-resistant polymicrobial PJI and mixed infection of the surgical wound. Despite the removal of the prosthesis, the positioning of double-stage exchange, and dehiscence debridement of the surgical wound, the infection continued. Positioning of an external fixator, plastic reconstruction with a skin graft, and continuous (two years) multiple antimicrobial therapy led to the resolution of the knee infection; a knee prosthesis was implanted, but a new infection of the extensus apparatus by multidrug-resistant Klebsiella pnumoniae followed. It was complicated by surgical wound dehiscence, forcing us to remove the prosthesis, put a new external fixator, and continue with the antibiotic treatment, with no results, and, finally, proceed to a leg amputation. Fourteen days after, the patient was discharged in good clinical condition but, fifteen days later, during rehabilitation in another hospital, the patient developed a severe Clostridium difficilis infection with profuse, intense diarrhea, toxic megacolon, and septic shock; despite colectomy and treatment in an intensive care unit, he died four months later. Patients affected by polymicrobial PJI are at high risk of treatment failure and, therefore, should be given a warning, in good time and appropriate form, of the likelihood of leg amputation.

Lateral Acromioplasty has a Positive Impact on Rotator Cuff Repair in Patients with a Critical Shoulder Angle Greater than 35 Degrees.

BACKGROUND: A Critical Shoulder Angle (CSA), evaluated on plain radiographs, greater than 35° is considered predictive of rotator cuff tears. The present prospective comparative study aimed, firstly, to develop a formula to calculate the amount of acromion that should be resected performing a lateral acromioplasty and, secondly, verify whether lateral acromioplasty to reduce the CSA associated with arthroscopic cuff repair decreased the rate of recurrence of the tears, and impacted favorably on clinical postoperative outcomes. METHODS: Patients undergoing arthroscopic rotator cuff repair (RCR) for rotator cuff tears with a CSA greater than 35° were included in this study and divided into two groups, based on whether the CSA had been reduced by arthroscopic resection of the lateral portion of the acromion. A new mathematical formula was developed in order to quantify the amount of bone to be resected while performing the lateral acromioplasty. Patients with traumatic tears, previous surgery, osteoarthritis or plain radiographs, not classified as A1 according to Suter-Henninger, were excluded. Clinical and radiographic outcomes were assessed at a minimum of 2 years of follow-up considering the tear size. RESULTS: 289 patients were included in this study. Thirty-seven were lost to follow-up. Group A (Lateral acromioplasty) patients included: 38 small tears, 30 medium tears, 28 large tears and 22 massive tears; Group B (control group) was composed of 40 small tears, 30 medium tears, 30 large tears and 23 massive tears. The Constants Score value and retear Rate were, respectively, significant higher (p = 0.007 and p = 0.004) and lower (p = 0.029 and p = 0.028) in Group A, both in the Small-and Medium-size subgroups. No complications were outlined. The mediolateral width of the acromion was reduced, according to the preoperatively calculated measure. CONCLUSION: Arthroscopic lateral acromioplasty decreased the CSA within the favorable range (30°-35°) in all patients treated, resecting the amount of bone predicted by the mathematical formula. Lateral acromioplasty is a safe and reproducible technique which may prevent recurrence of rotator cuff tears in patients with small and medium lesions. LEVEL OF EVIDENCE: II.

Clinical results of bony increased-offset reverse shoulder arthroplasty (BIO-RSA) associated with an onlay 145° curved stem in patients with cuff tear arthropathy: a comparative study.

BACKGROUND: The main limits of the Grammont design reverse shoulder arthroplasty (RSA) are loss of external rotation and scapular notching. They can be addressed with glenoid or humeral lateralization. The aim of the study was to compare outcomes of lateralized bony increased-offset RSA (BIO-RSA) vs. standard RSA in patients with an onlay 145° curved stem. METHODS: A comparative cohort study of 29 standard RSAs and 30 BIO-RSAs was performed. At 2 years postoperatively, Constant score, American Shoulder and Elbow Surgeons score, visual analog scale score, range of motion, and radiographs were evaluated. After comparison between the groups, patients were analyzed considering patients younger and older than 65 years. RESULTS: All parameters significantly improved after surgery in both groups. Postoperatively, the 2 groups did not show any clinical and radiographic differences (P > .05). In patients <66 years, BIO-RSA showed a significantly higher value of external rotation (49° ± 12° vs. 30° ± 19° [P = .025], elbow at side; 81° ± 17° vs. 56° ± 22° [P = .016], elbow at 90° of abduction) and a positive trend for all other parameters (P > .05). In patients >65 years, standard technique showed a positive trend for all the parameters (P > .05). No other significant differences were found. CONCLUSIONS: At 2 years of follow-up, the use of standard RSA or BIO-RSA in an implant with an onlay 145° curved stem provided similar outcomes. The humeral lateralization alone is sufficient to decrease notching and to improve external rotation. BIO-RSA increases external rotation in patients between 50 and 65 years old. Glenoid bone graft in RSA has a high incorporation rate (completed in 90%).

Reliability of quantitative point shear-wave ultrasound elastography on vastus medialis muscle and quadriceps and patellar tendons.

AIM: The aim of this work was to evaluate the reliability of pSWE in assessing the stiffness of the vastus medialis muscle and of the quadriceps and patellar tendons. MATERIAL AND METHODS: For this purpose, 18 subjects (9 males and 9 females of 57±22 years) in good clinical conditions were included in this study. pSWE examination was conducted by a unique expert operator with more than ten years of experience in musculoskeletal ultrasound. Two sets of five measurements for each muscle and tendon district were bilaterally performed at the same manner, at least fifteen minutes apart. The mean value of the measurements of each set was statistically compared with that of the other set. RESULTS: No significant differences were found comparing the mean value of the measurements of the two sets of evaluation performed in muscle and tendon areas (vastus medialis muscle: p=0.285; quadriceps tendon: p=0.979; patellar tendon: p=0.187). The intraclass correlation coefficient was excellent for all areas (vastus medialis muscle: 0.969; quadriceps and patellar tendons: 0.995 and 0.989, respectively). CONCLUSION:  The pSWE technique demonstrated that it was a reliable method for measuring stiffness in vastus medialis muscle and quadriceps and patellar tendon in subjects who had undergone orthopedic surgery. This opens the possibility of many applications in monitoring stiffness before and after surgery and during rehabilitation.

The role of the subscapularis tendon in a lateralized reverse total shoulder arthroplasty: repair versus nonrepair.

PURPOSE: The reverse shoulder prost hesis (rTSA) is now implanted by the same percentage of anatomic shoulder prosthesis in the USA. Scapular notching and loss of extrarotation have been underlined as complication at long-term follow-up due to the Grammont design. The current trend to reduce those limits is to position both components lateralized. As the role of the subscapularis tendon in this new rTSA design is unclear, the purpose of this study is to quantify rTSA outcomes in patients with or without subscapularis tendon suture. METHODS: The surgery was performed by the same orthopaedic surgeon (F.F.), using a Aequalis Ascend™ Flex prosthesis (Tornier, Montbonnot, France) with a bone autograft. Forty-four patients underwent surgery with the tendon sutured, whereas 40 patients underwent the same surgery without repairing it. Patients were evaluated pre-operatively and at the last follow-up using Constant score, VAS, and ROM. The minimum and mean follow-ups were six and 16.6 months, respectively. RESULTS: All patients showed statistically significant improvement in pain and joint function following surgery. This study highlighted significant higher values in intrarotation and abduction, respectively, with and without suturing the subscapularis tendon. However, no significant differences were underlined in Constant score, VAS, forward flexion, extrarotation at 0° and 90° of abduction, and rate of instability. CONCLUSIONS: As predicted, significant clinical improvements were observed in both groups with some differences. These clinical results showed that the use of rTSA with lateralized humerus and bony increase offset leads to realistic clinical improvements with a low risk of instability without the need for compression and stabilization of the tendon.

No difference between cemented and cementless total knee arthroplasty in young patients: a review of the evidence.

PURPOSE: The present piece of work provides improved knowledge about the evidence related to TKA in patients 60 years of age or younger, with special focus on fixation methods. Main concern of the review is to analyse the difference of survival rate and complications of cemented and cementless implants. METHODS: An electronic search was carried out between October and December 2015, through CINAHL, PubMed and the Cochrane Central Registry of Controlled Trials web databases. Articles in English, Italian, French and Spanish were considered for inclusion. Only peer-reviewed studies with adult patients aged 60 years or less, with diagnosis of osteoarthritis in more than 90% of the subjects, were considered for inclusion. All studies had to report outcomes after TKA with either cemented or cementless fixation technique. RESULTS: No significant differences in terms of clinical, functional and radiological outcomes were found between cemented and cementless implants. Good clinical and functional results were obtained in terms of the Knee Society score and Western Ontario and McMaster Universities Osteoarthritis Index for both techniques. Radiographic results showed that radiolucent lines of <2 mm in width were detected at radiographs, without difference between cemented or cementless implants. Well-conducted trials on cemented versus cementless TKA were carried out in few papers. A survival rate of over 90% was reported in the majority of the studies at a mean follow-up of 8.6 years (range 5-18 years). CONCLUSION: Similar results were observed in terms of functional outcome and survival rates for both cemented and cementless TKAs. High survival rates were reported for both operative techniques and cemented TKA did not offer additional benefit. Assuming that cementless prosthesis allows a stable fixation and reduces the time of operation, the authors recommend the cementless fixation as a primary choice in the investigated patient population. However, evidence is low, and further research is needed. LEVEL OF EVIDENCE: IV.

Double-Row Repair Lowers the Retear Risk After Accelerated Rehabilitation.

BACKGROUND: Recently, an accelerated rehabilitation protocol after rotator cuff (RC) repair has been proposed for patients at risk of postoperative stiffness. PURPOSE: To investigate, in patients undergoing early accelerated mobilization, whether double-row (DR) repair provides better clinical outcomes and a lower retear rate compared with single-row (SR) configurations. STUDY DESIGN: Randomized controlled trial; Level of evidence, 1. METHODS: A total of 58 patients were randomized to undergo either SR or DR repair. After 2 years of follow-up, 12 men and 13 women (mean age, 61.8 years; range, 52-67 years) in the SR group and 15 men and 10 women (mean age, 58.9 years; range, 51-69 years) in the DR group were evaluated. To assess the retear rate, magnetic resonance imaging of the shoulder was performed at 2-year follow-up. The clinical evaluation was based on the modified University of California, Los Angeles (UCLA) shoulder score and range of motion (ROM) measurements. RESULTS: Magnetic resonance arthrography showed a significantly lower full-thickness retear rate for the DR group than for the SR group (8% vs 24%, respectively; P < .05). Conversely, at both 6-month and 2-year follow-up, there was no statistically significant difference in terms of the rate of stiffness in the SR and DR groups (8% vs 12% and 0% vs 0%, respectively; P > .05). No clinical differences were recorded regarding the UCLA score (SR group: mean, 32.6 [range, 30-35]; DR group: mean, 33.3 [range, 29-35]; P = .61) and ROM. CONCLUSION: In selected patients at a high risk of shoulder stiffness and therefore necessitating accelerated postoperative rehabilitation, DR repair of the RC could lower retear rates.

Diagnosis and management of olecranon bursitis.

We aim to review the current knowledge on diagnosis, clinical features and main management modalities of olecranon bursitis. We underline that the first treatment line is conservative, including ice, rest, anti-inflammatory and analgesic drugs and, occasionally, bursal fluid aspiration. In unresponsive patients, although open excisional procedures allow to completely remove the pathological bursal tissue, arthroscopy is increasingly being considered as a suitable new modality of management. These minimally invasive procedures, although not free from complications, avoid the wound problems often occurring following open excision.

Synovial sarcoma of the anterior tibialis tendon.

We report the clinical features, radiographic findings, management and results of a patient with a post-traumatic synovial sarcoma of the anterior tibialis tendon. Our patient was managed operatively and with radiotherapy with good clinical results. No evidence of recurrence or metastatic disease was seen at 3-year follow-up.

Operative management of partial- and full-thickness rotator cuff tears.

Repair of rotator cuff tears (RCT) is challenging. In RC tears, a partial (PTRCTs) or full (RCTs) discontinuation of one or more of the muscles or tendons and may occur as a result of traumatic injury or degeneration over a period of years. Many factors seem to contribute to the final outcome and a considerable number of variations during the decision-making process of patients with RCTs exist. Accurate diagnosis is fundamental to guide correct management, and the tear pattern should be carefully evaluated to plan the appropriate repair. Both non-operative and operative treatments are used to relieve pain and restore movement and function of the shoulder. Different surgical options are available. The present review describes the current evidence about diagnosis and management of partial and complete rotator tears.

Management of postoperative shoulder stiffness.

Arthroscopic surgery has become the most popular treatment to repair rotator cuff tears. Although the exact prevalence of postoperative stiffness is unknown, many studies report an incidence rate of 4% to 15%. Management of postoperative shoulder stiffness depends on the cause of the stiffness. Nonoperative and operative management modalities are available, but postoperative shoulder stiffness is often resistant to nonsurgical management. When conservative treatment fails, surgical release of the scar tissue and adhesions can be performed both by arthroscopic or open surgery. Arthroscopic capsular release is the preferred technique for capsule contraction and adhesion formation, as it allows precise and selective debridement of the scar tissue and division of the shortened and thickened capsule by partial or extensive capsulectomy.

Quantitative review of operative management of hallux rigidus.

INTRODUCTION: Surgical techniques for the management of hallux rigidus include cheilectomy, Keller resection arthroplasty, arthrodesis, Silastic implantation, phalangeal or metatarsal osteotomy, capsular arthroplasty, partial or total joint replacement, interposition arthroplasty. However, the optimal management is controversial. SOURCES OF DATA: We performed a comprehensive search of CINAHL, Embase, Medline and the Cochrane Central Registry of Controlled Trials, from inception of the database to 2 November 2010. Sixty-nine articles published in peer reviewed journals were included in this comprehensive review. AREAS OF AGREEMENT: Cheilectomy and first metatarsal or phalangeal corrective osteotomy may provide better outcome for patients with early and intermediate hallux rigidus (Stages I-II), while arthrodesis or arthroplasty are indicated to manage more severe conditions. The Coleman Methodology Score showed great heterogeneity in terms of study design, patient characteristics, management methods and outcome assessment and generally low methodological quality. AREAS OF CONTROVERSY: Definitive conclusions on the use of these techniques for routine management of patients with hallux rigidus are not possible. Given the limitations of the published literature, especially the extensive clinical heterogeneity, it is not possible to compare outcomes of patients undergoing different surgical procedures and determine clear guidelines. GROWING POINTS: To assess whether benefits from surgery, validated and standardized measures should be used to compare the outcomes of patients undergoing standard surgical procedures. RESEARCH: There is a need to perform appropriately powered randomized clinical trials of using standard diagnostic assessment, common and validated scoring system comparing reported outcomes and duration of follow-up >2 years.

Usefulness of ultrasound-guided fine-needle aspiration cytology in the diagnosis of non-palpable small thyroid nodules.

AIMS AND BACKGROUND: Diverse and contradictory approaches have been suggested for the management of non-palpable thyroid nodules. The aim of our study was to evaluate the indications and limits of ultrasound-guided fine-needle aspiration cytology (US-FNAC) in non-palpable infracentimetric thyroid nodules. METHODS AND STUDY DESIGN: From September 2003 to December 2004 we observed 325 patients with non-palpable thyroid nodules. We divided our series into three groups according to the diameter of the lesion in order to verify the effectiveness of US-FNAC for lesions of less than 1 cm. RESULTS: We assessed the cases with satisfactory and unsatisfactory results in the three groups into which the sample was divided (4 mm to 1 cm; 10.1 mm to 15 mm, and 15.1 mm to 25.5 mm). Our statistical analysis by means of the z-test showed there was no significant (5%) difference in the percentage distribution of the unsatisfactory results in the three groups. CONCLUSIONS: Fine-needle cytology appears to be a useful diagnostic tool also for nodules of less than one cm because the percentage of unsatisfactory results is not related to the size of the nodule.
