Introduction. Stemless anatomic implants are the growing standard for solving osteoarthritis of the shoulder. If there are secondary rotator cuff insufficiency and the need to revise the implant into a reverse total shoulder, there is usually the option to revise it into a stemmed implant with losing the benefits of stemless implants. There are only a few stemless reverse implants available on the market. Usually, they are recommended as primary implants, but not for revision surgery. Case Report. A 61-year-old male with an indwelling anatomic stemless TESS (Total Evolutive Shoulder System, Zimmer Biomet, Warsaw, USA) implant presented in our clinic with growing pain and loss of range of motion. The TESS was implanted in 2007 as a hemishoulder arthroplasty. The X-ray was showing a stable implanted corolla with clearly growing protrusion of the glenoid. Because of the clinical presentation and the ultrasound investigation that showed only remnants of the supraspinatus and infraspinatus left, we decided that it is necessary to revise the stable implant in a reverse total shoulder arthroplasty. As the TESS was not designed to be convertible, it was clear that it has to be explanted. Due to the young age of the patient, we proposed an “off-label” change to a stemless reverse implant, e.g., the LIMA SMR stemless reverse prosthesis. A revision was possible without much bone loss, so the stemless reverse implant could be used. The clinical and radiological 2-year follow-up showed a good result. Conclusion. Stemless implants are well known for anatomic implants, rarely for reverse implants, and seldom used for revision into reverse stemless. This case report shows that it is possible to revise a stemless anatomic implant with a stemless reverse, as long as the rules for implantation are applicable.

Introduction: Congenital Syphilis (CS) occurs through the transplacental transmission of Treponema pallidum in inadequately treated or non-treated pregnant women, and is capable of severe consequences such as miscarriage, preterm birth, congenital disease and/or neonatal death. CS has been showing an increasing incidence worldwide, with an increase of 208% from 2009 to 2015 in Brazil. Case report: 2-month old infant receives care in emergency service due to edema of right lower limb with pain in mobilization. X-ray with osteolytic lesion in distal fibula. Infant was sent to the Pediatrics Oncology clinic. Perinatal data: 7 prenatal appointments, negative serology at 10 and 30 weeks of gestation. End of pregnancy tests were not examined and tests for mother’s hospital admission were not requested. Mother undergone elective cesarean section at 38 weeks without complications. During the pediatric oncologist appointment, patient showed erythematous-squamous lesions in neck and other scar-like lesions in upper body. A new X-ray of lower limbs showed lesions in right fibula with periosteal reaction associated with aggressive osteolytic lesion compromising distal diaphysis, with cortical bone rupture and signs of pathological fracture, suggestive of eosinophilic granuloma. She was hospitalized for a lesion biopsy. Laboratory tests: hematocrit: 23.1 / hemoglobin 7.7 / leukocytes 10,130 (without left deviation) / platelets 638,000 / Negative Cytomegalovirus IgG and IgM and Toxoplasmosis IgG and IgM / VDRL 1:128. Congenital syphilis diagnosis with skin lesions, bone alterations and anemia. Lumbar puncture: glucose 55 / total proteins 26 / VDRL non reagent / 13 leukocytes (8% neutrophils; 84% monomorphonuclear; 8% macrophages) and 160 erythrocytes / negative VDRL and culture. X-ray of other long bones, ophthalmological evaluation and abdominal ultrasound without alterations. Patient was hospitalized for 14 days for treatment with Ceftriaxone 100mg/kg/day, due to the lack of Crystalline Penicillin in the hospital. She is now under outpatient follow-up. Discussion: CS is responsible for high rates of morbidity and mortality. The ongoing increase of cases of this pathology reflects a severe health issue and indicates failures in policies for the prevention of sexually transmitted diseases, with inadequate follow-up of prenatal and maternity protocols.

Aims The reasons for failure of a hemirthroplasty (HA) when used to treat a proximal humeral fracture include displaced or necrotic tuberosities, insufficient metaphyseal bone-stock, and rotator cuff tears. Reverse total shoulder arthroplasty (rTSA) is often the only remaining form of treatment in these patients. The aim of this study was to evaluate the clinical outcome after conversions from a failed HA to rTSA. Material and Methods A total of 35 patients, in whom a HA, as treatment for a fracture of the proximal humerus, had failed, underwent conversion to a rTSA. A total of 28 were available for follow-up at a mean of 61 months (37 to 91), having been initially reviewed at a mean of 20 months (12 to 36) postoperatively. Having a convertible design, the humeral stem could be preserved in nine patients. The stem was removed in the other 19 patients and a conventional rTSA was implanted. At final follow-up, patients were assessed using the American Shoulder and Elbow Surgeons (ASES) score, the Constant Score, and plain radiographs. Results At final follow-up, the mean ASES was 59 (25 to 97) and the mean adjusted Constant Score was 63% (23% to 109%). Both improved significantly (p < 0.001). The mean forward flexion was 104° (50° to 155°) and mean abduction was 98° (60° to 140°). Nine patients (32%) had a complication; two had an infection and instability, respectively; three had a scapular fracture; and one patient each had delayed wound healing and symptomatic loosening. If implants could be converted to a rTSA without removal of the stem, the operating time was shorter (82 minutes versus 102 minutes; p = 0.018). Conclusion After failure of a HA in the treatment of a proximal humeral fracture, conversion to a rTSA may achieve pain relief and improved shoulder function. The complication rate is considerable.

Background: To evaluate clinical and radiological outcomes of bony increased offset-reverse total shoulder arthroplasty (BIO-RSA) in the Asian population at mid-term follow-up.Methods: From June 2012 to August 2017 at a single center, 43 patients underwent BIO-RSA, and 38 patients with a minimum of 2 years of follow-up were enrolled. We evaluated the preoperative and postoperative clinical outcomes, radiological outcomes (notching and loosening), and complications of BIO-RSA at the last follow-up. In addition, we divided these patients into notching and not-notching groups and compared the demographics, preoperative, and postoperative characteristics of patients between the two groups.Results: Visual analog scale, American Shoulder and Elbow Surgeons, University of California-Los Angeles, and Simple Shoulder Test scores improved significantly from preoperative (average: 5, 39.43, 16.22, 3.94) to postoperative (average: 1.71, 78.91, 28.34, 7.8; p<0.05) outcomes. All range of motion except internal rotation improved significantly at the final follow-up (p<0.05), and the bone graft was well-incorporated with the native glenoid in all patients (100%). However, scapular notching was observed in 20/38 patients (53%). In the comparison between notching and not-notching groups (18 vs. 20 patients), there were no significant differences in demographics, radiological parameters, and clinical outcomes except acromion-greater tuberosity (AT) distance (p=0.003). Intraoperative complications were three metaphyseal fractures and one inferior screw malposition. Postoperative complications included one heterotopic ossification, one scapula neck stress fracture, one humeral stem loosening, and one late infection.Conclusions: BIO-RSA resulted in improved clinical outcomes at mid-term follow-up in the Asian population. Although better cosmesis and advantages of glenoid lateralization were observed, we observed higher rates of scapular notching compared to previously reported rates in BIO-RSA studies. In addition, adequate glenoid lateralization with appropriate humeral lengthening (AT distance) might reduce scapular notching.

A man in his mid-80s presented with bilateral posterior fracture dislocations of the humerus after suffering a seizure. He had Parskinson’s disease and lived with his wife at home. His left shoulder was not felt to be reconstructable. The initial treatment plan was to perform reverse total shoulder arthroplasty (rTSA) on the left and non-operatively reduce his right shoulder. A left rTSA was performed, but his right shoulder was unstable due to a glenoid fracture and soft tissue instability. In order to preserve the patient’s quality of life, a right rTSA was performed 4 days later. In the follow-up period, the patient was able to regain enough pain-free range of motion on activities of daily living. The patient died from complications of Parkinson’s disease 10 months postoperatively.

Background The purpose of this study was to prospectively compare clinical outcomes of reverse total shoulder arthroplasty (RTSA) combined with latissimus dorsi transfer by modified L’Episcopo (Group I) versus the greater tuberosity (Group II) in patients with lack of elevation and external rotation in the shoulder. Materials and methods Eighteen patients participated in the study. They were placed randomly into two groups of nine patients in each group. The results were evaluated prior to surgery and at the end follow-up. Results The average follow-up was 33.2 months. The mean ASES scores improved from 13 points to 79 in Group I and from 15 to 73 in Group II. The mean Constant shoulder scores improved from 19 to 66 in Group I and from 18 to 67 in Group II. Mean active elevation increased from 59° to 147° in Group I and from 58° to 148° in Group II. The mean external rotation scores increased from −43° to 7° in Group I and from −41° to 23° in Group II. Conclusion Comparing clinical outcomes and active elevation, there were no significant differences. The latissimus dorsi transfer to the greater tuberosity provided greater external rotation than did the modified L’Episcopo transfer.
