Background: Total shoulder arthroplasty (TSA) and hemiarthroplasty (HA) have shown good clinical outcomes in primary avascular necrosis of the humeral head (PANHH) both in short and long terms. The purpose of this study was to assess the complications, the clinical and radiological outcomes of shoulder arthroplasty in young patients with PANHH. Methods: One hundred and twenty-seven patients aged under 60 years old and suffering from PANHH were operated with arthroplasty. Patients were assessed clinically and radiographically before surgery with a minimum of 2 years of follow up (FU). Results: HA was performed on 108 patients (85%). Two patients were revised for painful glenoid wear after 2 and 4 years. TSA was performed on 19 patients (15%). Five TSA had to be revised for glenoid loosening (n = 4) or instability (n = 1). Revision rate was 26% with TSA and 2% with HA. There were no significant differences between HA and TSA in terms of clinical outcomes. Conclusions: With a mean FU of 8 years, HA and TSA improved clinical outcomes of patients with PANHH. HA revisions for painful glenoid wear were rare (2%). The revision rate was excessively high with TSA (26%).

Martinel et al described an intraoperative ultrasound technique to easier identify calcification (CA) under arthroscopy. Our hypothesis was that intraoperative ultrasound monitoring allowed better evacuation of calcific tendinopathy. Our aim was to determine whether ultrasound monitoring improved the short-term clinical and radiological outcomes of calcific tendinopathy. A prospective, single-center, single-operator, consecutive study conducted between February 2020 and June 2023. The inclusion criterion was surgical treatment for evacuation of symptomatic macro-centimetric CA type A or B. The first 20 patients were operated on using the standard surgical technique and the next 20 under ultrasound control. The mean age at surgery was 49.8 years (minimum: 28 years; maximum: 64 years). Patients were reviewed at 6 weeks and 3 months. The evacuation of the CA was checked at 6 weeks by X-ray. In the standard technique group, the mean preoperative Constant score was 41.4/100 (±15.07). Postoperatively, the Constant score was 58.88/100 (±15.28) at 6 weeks and 69.16/100 (±13.86) at 3 months. The mean preoperative Subjective Shoulder Value (SSV) was 39.0% (±18.61). Postoperatively, the SSV was 64.0% (±17.21) at 6 weeks and 79.47% (±16.06) at 3 months. In the ultrasound control group, the preoperative Constant score was 44.48/100 (±14.28) and 58.18/100 (±15.64) at 6 weeks and 66.87/100 (±18.45) at 3 months postoperatively. The mean preoperative SSV was 40.0% (±16.54) and 61.75% (±18.59) at 6 weeks and 76.05% (±19.62) at 3 months postoperatively. There was no significant postoperative difference in Constant score (P = .732) or SSV (P = .566) between the 2 groups. There was a significant difference (P = .004) between the 2 groups in terms of complete evacuation of the CA with the standard technique in 65% of cases (13 patients out of 20) and with intraoperative ultrasound monitoring in 95% of cases (19 patients out of 20). There was no significant postoperative difference in Constant score and SSV between the 2 groups in the short term. Evacuation of calcification was significantly better with ultrasound monitoring.
