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. ⋯ 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.

There is growing support in the literatures that peri-operative outcomes are adversely affected by surgical case order in some certain surgical procedures. This study aimed to examine if similar phenomenon is also shared in total joint arthroplasty (TJA). ⋯ Surgical case order is an independent risk factor for arthroplastic adverse events in TJA. TJA procedures performed later in the day have a higher risk for arthroplastic adverse events, but not for systematic adverse events. Significantly increased operative time, higher cost, and longer LOS were noted for fourth or later TJA cases. Data in our study reveals that performing more than three TJAs within a single day may imply compromised outcomes.

Infected non-unions present a clinical challenge, especially with risk of recurrent infection. Bone marrow contains granulocyte precursors identified in vitro as colony forming units-granulocyte macrophage (CFU-GM) have a prophylactic action against infection. We therefore tested the hypothesis that bone marrow concentrated granulocytes precursors added to a standard bone graft could decrease the risk of recurrence of infection when single-stage treatment of infected tibial non-unions is performed with bone graft. ⋯ Supercharging the cancellous bone graft with bone marrow granulocytes precursors protect the site of infected non-union from recurrence of infection and bone resorption of the graft.

Periprosthetic femoral fracture as cause of early revision after short stem hip arthroplasty-a multicentric analysis.
The objective of this study was to analyze the prevalence and causes of early re-operation after hip replacement surgery using short bone-preserving stems in a large multicentre series. Specifically, we evaluated the clinical features of periprosthetic fractures occurring around short stems. ⋯ Periprosthetic femoral fracture was the major reason for re-operation after hip replacement surgery using short bone-preserving stems accounting for 50% (8/16) of re-operations two years post-operatively, but did not seem to deteriorate survivorship of implanted prostheses.

Multicenter Study
Association of pre-treatment radiographic characteristics of calcaneal fractures on patient-reported outcomes.
Calcaneal fractures are known to influence patients' quality of life negatively. The type of calcaneal fracture might have a relation with the patient outcome. To inform patients in an early stage on how their calcaneal fracture may affect their lives, knowledge of the fracture characteristics is necessary. This study evaluates the association of type of calcaneal fracture, measurement of conventional radiograph angles, and the Sanders classification with patient-reported outcomes. ⋯ Our study implies that patients with an intra-articular calcaneal fracture into the talar surface have a lower health-related quality of life, will be less satisfied with the outcome of their feet, and have more complications compared to patients with other type of calcaneal fractures. Furthermore, the Sanders classification was not associated with the patient-reported outcomes.
