Titanium mini locking plate with trans-osseous sutures for the treatment of humeral greater tuberosity fracture osteosynthesis versus PHILOS: a retrospective view
Abstract
Purpose
Greater tuberosity fractures (GTFs) account for 17 to 21% of proximal humerus fractures, most of these fractures are treated conservatively, but treatment for displaced fractures is still controversial. The aim of this study is to compare intra-operative clinical conditions and post-operative outcomes when displaced GTFs are treated with either proximal humeral internal locking system (PHILOS) or mini locking plate with trans-osseous sutures.
Methods
This is a retrospective study conducted in Shanghai Tenth People’s Hospital. A total of 60 patients (22 males and 38 females) with displaced humeral GTF between May 2013 and March 2017 were included, of whom 43 underwent PHILOS implant treatment and 17 underwent titanium mini plate implant with trans-osseous suture treatment. Intra-operative (incision size, intra-operative blood loss, operative duration) and postoperative (Constant-Murley score (CMS) and implant cost) variables were recorded for the comparison.
Results
Mini locking plate with trans-osseous sutures shows better results. Operative duration (PHILOS mean 77.0 minutes vs mean 63.7 minutes, p value < 0.05), blood loss during surgery (PHILOS mean 111.5 vs 66.5 ml, p value < 0.05), incision size (PHILOS mean 7.2 vs 4.6 cm, p value < 0.05), CMS (PHILOS mean 81.0 vs 87.3, p value < 0.05), and implant costs (PHILOS mean 26,192.6 renminbi (RMB) vs mean 21,358.8 RMB, p value < 0.05). On the other hand, 9.30% of impingement in the PHILOS group was observed to have no complications compared to the mini locking plate group.
Conclusions
Mini locking plate with trans-osseous sutures shows better efficacy in reducing the incision size, operative duration, intraoperative blood loss, and implant cost and in improving CMS. No complication was found with its use. Our data can provide rationale and inform sample- size calculations for such studies. Larger, control studies are needed for better understanding.
