Overview
Brief Summary
The study is a monocentric, retrospective, non-randomized, non-controlled and consecutive series post-market study. The purpose of this study is to confirm safety, performance and clinical benefits of the Reconstruction System (implants and instrumentation) when used for temporary internal fixation and stabilization of fractures during the normal healing process.
The primary objective is the assessment of performance by analyzing fracture healing.
The secondary objectives are the assessment of safety by recording and analyzing the incidence and frequency of complications and adverse events. Relation of the events to implant, instrumentation and/or procedure should be specified. Subjects' outcomes will also be assessed.
Detailed Description
The Reconstruction System is especially used to stabilize pelvic ring and acetabulum fractures. One site will be involved in this study. The aim is to include a maximum of 83 consecutive series cases who received the Zimmer Reconstruction System at the Azienda Ospedaliero Universitaria Senese (Siena, Italy) between 2010 and 2018. All potential study subjects will be required to participate to the Informed Consent process. Baseline data from the preop, intraop, immediate post-op and last consultation visit will be available in medical notes and collected retrospectively. In addition, any complications since the last consultation visit at the clinic and information about the treatment of the complications will also be collected retrospectively.

Outcomes
Primary Outcomes
Performance: Fracture Healing
Time Frame: Mean time of 1.99 years after the surgery
Performance will be assessed by analyzing fracture healing radiographically by X-rays.
Secondary Outcomes
- Product Safety(Mean time of 1.99 years after the surgery)
- Harris Hip Score(Mean time of 1.99 years after the surgery)
