Event Description
This report is being filed after the review of the following journal article: cheng h. , et al (2021) treatment of 2-part proximal humeral fractures in osteoporotic patients with medial calcar instability using a philos plate plus an allogeneic fibula inserted obliquely ¿ a retrospective study, geriatric orthopaedic surgery & rehabilitation volume 12: 1¿8, pages 1-8 (china). This retrospective aims to assess the outcomes of elderly individuals with severe osteoporotic 2-part proximal humerus fractures (phfs) combined with medial column (calcar) instability or disruption who were treated with a proximal humeral internal locking system (philos) plate combined with a humeral calcar inserted obliquely using an allogeneic fibula at an angle of 120° to the longitudinal axis of the humerus shaft (an angled allogeneic fibula insertion technique) for maintaining this reduction. One hundred and twelve consecutive elderly individuals sustaining severe osteoporotic 2-part phfs combined with medial column (calcar) instability or disruption were identified from 3 tertiary medical centres from (b)(6) 2014 to (b)(6) 2019. Of 112 patients, 26 (23. 2%) were excluded according to the present criteria, as presented in. Leaving 86 eligible patients from whom all relevant information was available met the inclusion and exclusion criteria. There were 39 men and 47 women. Mean age was 68. 8 ( ± 5. 2) years. The philos plate (synthes, solothurn, switzerland) was used. Follow-ups occurred at 3 months, 6 months and 12 months after surgery and yearly thereafter. Median followup was 24 (15. 3¿27. 6) months. Reported complications: 4 individuals had loss of reduction, 4 experienced postoperative loosening, 1 had non-union, 4 suffered a periprosthetic fracture, 1 had a dislocation related to a malreduction, 5 suffered an unbearable shoulder pain. Revision was mostly attributed to periprosthetic fractures. One case was revised with a reverse total shoulder arthroplasty (zimmer, (b)(4), usa); 2 cases underwent a semi-shoulder joint replacement (trabecular metal; zimmer, (b)(4), usa). 3 experienced a revision surgery which was mainly attributed to postoperative loosening and dislocation. 4 aseptic loosening. This report is for unk - plates: philos. A copy of the literature article is being submitted with this medwatch. This is report 2 of 4 for (b)(4).
