Introduction: A new type of periprosthetic fracture, between Vancouver-SoFCOT types A and B, was recently described and labeled "new B2". It occurs intraoperatively or in the early postoperative period, on cementless implants, and features a posteromedial cortical fragment around the lesser trochanter. The main aim of the present study was to report clinical and radiological results in a series of 33 cases of what is better called Vancouver B-lesser trochanter (VB-LT) fracture. The secondary objective was to identify risk factors. The study hypothesis was that VB-LT fracture might occur in the late postoperative course., Material and Method: A2 single-center retrospective study included all patients with postoperative periprosthetic VB-LT fracture diagnosed on standard X-ray. Treatment was operative or non-operative depending on femoral implant subsidence and the patient's general health status., Results: There were 33 VB-LT fractures out of 445 periprosthetic femoral fractures (7.5%), in 27 women and 6 men; all were postoperative, at a mean 47 months (range, 1 day to 20 years). Mean subsidence of the femoral stem was 8.8mm, in 73% of cases (24 out of 33 implants). The 9 VB-LT1 fractures (without subsidence) were treated non-operatively, without secondary displacement. Thirteen of the 24 VB-LT2 fractures (with subsidence) were managed by stem exchange and cerclage; 3 other patients had isolated stem exchange, 2 had isolated internal fixation by cerclage, and 6 in poor health were managed non-operatively. At a mean 28 months' follow-up (range, 6-48 months), mean PMA score was 15.5 (range, 10-18), Harris Hip score 72.4 (range, 43-100) and Parker score 7.2 (range, 4-9). All cases showed osseointegration and implant stability; there was 1 case of non-union, without impact on stability., Conclusion: Postoperative Vancouver B-lesser trochanter fracture seemed specific to cementless implants and did not occur exclusively in the early postoperative period. Non-operative treatment gave good results when there was no implant subsidence (type VB-LT1)., Level of Evidence: IV, retrospective., (Copyright © 2022 Elsevier Masson SAS. All rights reserved.)

Introduction: Outpatient surgery in France is defined by the national authority for health (HAS) as a scheduled surgery enabling same-day discharge without any increased risk to the patient. With the advent of enhanced recovery after surgery, outpatient lower limb arthroplasty has become a common procedure. However, only 1.1% of knee arthroplasties in France were performed on an outpatient basis in 2017., Objectives: 1) assess early morbidity and mortality after outpatient shoulder arthroplasties to validate eligibility and safety criteria; and 2) assess patient acceptance of outpatient surgery., Methods: A single-center study with the following inclusion criteria: primary shoulder arthroplasty, American Society of Anesthesiology (ASA) score I or II, no cognitive impairment, and no coronary artery or thromboembolic diseases. Analgesia was provided by bupivacaine via a peripheral nerve catheter in the first 72 hours followed by oral analgesics. Patients were discharged if the post-anesthetic discharge scoring system (PADSS) was>9/10 and the visual analog scale (VAS) was<5/10. Postoperative telephone interviews were carried out on D1, D2 and D3 to assess pain with the numerical rating scale and to collect data on their analgesic consumption. All patients were seen by an independent observer at one and six months for a clinical and radiologic follow-up and at 90 days during a consultation with the senior surgeon. The primary endpoint was the 90-day morbidity and mortality rate (readmissions, rehospitalizations, and minor and major complications). A satisfaction questionnaire was collected at one and six months., Results: Thirty-six patients were offered an outpatient shoulder arthroplasty between February 2016 and February 2018: 12 (33%) refused with no valid reasons and 24 patients agreed to the procedure (seven hemiarthroplasties, nine anatomic shoulder arthroplasties and eight reverse shoulder arthroplasties). The mean age at surgery was 70 years (55-82), mean body mass index (BMI) was 26 (21-32) and 14 patients were ASA II (66%). Three patients (12%) refused same-day discharge despite a PADSS score>9/10 and adequate pain management. Two patients (8%) were not discharged home on the same day as the surgery for medical reasons (one for pain and one for high blood pressure). No readmissions or complications were reported for the 19 outpatient arthroplasties. None of the outpatients used opioids. All patients were satisfied with their functional outcome, 84% were satisfied with the outpatient management and 17% felt they were insufficiently monitored and regretted that they were not hospitalized., Conclusions: 1) outpatient shoulder arthroplasty can be safely proposed to selected patients with low comorbidities, regardless of their age and type of implant; 2) the acceptance rate for outpatient shoulder arthroplasty remained low among our patient population. These results should incite us to better educate patients about outpatient surgery., Level of Evidence: IV; retrospective study., (Copyright © 2021. Published by Elsevier Masson SAS.)
