Evaluation of the Clinical Efficacy of Y-STRUT® Medical Device Implanted for Contralateral Percutaneous Internal Fixation of Proximal Femur, in Patient With a Low Energy Per Trochanteric Fracture on the First Side

Study Overview
=================
Brief Summary
-----------------
HIP50 is a national, multicentre, prospective, observational study, in patients presenting a first low energy per trochanteric hip fracture on one side and treated with Y-STRUT® device implanted on the contralateral proximal femur as percutaneous internal fixation to prevent contralateral hip fracture in case of osteoporosis. The primary objective of this study is to evaluate the clinical efficacy of the studied medical device by measuring the frequency of patient with a fracture at the implantation site within 1 year after implantation. A total of 50 patients from France will be enrolled (until December 2020) and followed up to 24 months.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Frequency of post-operative fracture [Clinical efficacy of the device] | Frequency of Y-STRUT® implanted patients with a fracture at the implantation site | At 12 months | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Frequency of post-operative fracture [Clinical efficacy of the device] | Frequency of Y-STRUT® implanted patients with a fracture at the implantation site | At 3 and 24 months | 
| Recording of concomitants treatments [safety and feasibility of the device] | Recording of all concomitants treatments: analgesic for pain, anti-osteoporotic treatment and other treatments. | At 3, 12 and 24 months | 
| Pain [safety and feasibility of the device] | Self-evaluation of hip pain using VAS (Visual Analogue Scale), going from 0 (no pain) to 10 (maximum). | At 3, 12 and 24 months | 
| Walking conditions [safety and feasibility of the device] | Assessment of resumption of weight-bearing (yes/no, aid) | At 3, 12 and 24 months | 
| Recording of adverse events and device effects [safety and feasibility of the device] | Recording of the medical device vigilance: all serious adverse events, all adverse events linked to the device or the operative technique, and any other important event reported. | At 3, 12 and 24 months | 
| Surgical procedure duration [learning curve of the procedure] | Measuring mean/median intervention duration of each procedure. Then, all the durations of successive procedures will be compared among all the investigators. | At the end of the inclusion period (24 months from the first included patient) | 
| Hospitalisation duration [learning curve of the procedure] | Measuring mean/median hospitalisation duration. Then, all the durations of successive hospitalisations will be compared among all the investigators. | At the end of the inclusion period (24 months from the first included patient)] | 
| Rate of complications [learning curve of the procedure] | Assessing types and frequencies of procedures complications (per-op and post-op). Then, all the rate of complications will be compared among all the investigators. | At the end of the inclusion period (24 months from the first included patient) |
