The CHINA TFNA Study
Femur FracturesThis is a prospective, multicenter, randomized, controlled, two-arm, non-inferiority study which will be conducted in China to support registration of a cephalomedullary nailing system (TFNA) that currently is available globally. The study will compare the safety and the effectiveness of two intramedullary nails (the investigational group is TFNA and the control group is PFNA-II).Patients enrolled at each site will be randomized in a ratio of 1:1, i.e. one patient assigned to surgery implanted with TFNA for each patient assigned to PFNA-II. Separate block randomization schedules within each site will be used to ensure equal distribution of treatment and control patients. Up to 15 centers will be approved to participate in this study. Patient will be clinically followed after surgery at 1, 6, 12 and 24 weeks. The data up to and including 24 week follow up visit will be used in determining the primary safety and effectiveness of the TFNA. The primary objective of this study is to evaluate whether fracture union rate, evaluated 24 weeks after proximal femur fracture, for the investigational TFNA intramedullary nail is non-inferior to that for currently available control product PFNA-II in patients with proximal femur fractures.

CM Asia Nail With AS2 Without AS2 (AS2 Study)
Trochanteric Fracture of FemurThe purpose of this study is to compare reduction positon maintenance rate at 3 weeks post-operatively between patients operated with Anterior Support Screw (AS2) and without AS2 technique in RCT setting. Total 240 cases(each arm 120 cases) will be enrolled at maximum 15sites, total study duration is 22months.

ZNN Bactiguard Retrograde Femoral Nails PMCF Study
Femoral FracturePost-market clinical follow-up (PMCF) study to confirm the safety, performance, and clinical benefits of the intra-medullary retrograde femoral nail Zimmer Natural Nail (ZNN) Bactiguard (implants and instrumentation) when used for the temporary internal fixation and stabilization of femoral fractures.

Clinical Evaluation on HA Coated Dynamic Hip Screws for Trochanteric Femoral Fractures
Intertrochanteric FracturesEvaluated whether HA coated dynamic hip screws can improve fixation of the screw in trochanteric femoral fractures

Femur Transtrochanteric Fractures Treated With Dynamic Hip Screw and Calcium Sulfate Scaffold.
Proximal Femur FractureThis is a randomised prospective comparison study to evaluate the incidence of cut - out failure of the dynamic hip screw implant alone compared to the dynamic hip screw adding calcium sulfate through the cervical canal before placing the sliding screw for improvement of the implant stability integration and bone healing.

Efficacy of Peri-Incisional Multimodal Drug Injection Following Operative Management of Femur Fractures...
PainPostoperative1 moreThe purpose of this study is to determine the efficacy and safety of a peri-incisional multimodal injection for post-operative pain control following operative management of femur fractures. Enrolled subjects will be prospectively randomized into either the peri-incisional injection or control cohorts. Patients will be treated with standard of care surgical techniques by the treating orthopaedic surgeon for the patient's specific fracture pattern. The patients randomized into the injection cohort will receive an intra-operative injection with 400 mg ropivacaine, 0.6 mg epinephrine, 5 mg and morphine into the local superficial and deep peri-incisional tissues while under general anesthesia. Visual analog pain scores will be collected every 4 hours after surgery for the first two post-operative days. Total narcotic consumption will also be recorded over eight hour intervals for the first two post-operative days. Medication related side effects will be monitored. The investigators hypothesize that the peri-incisional injection cohort will demonstrate an improved pain profile and utilize less parenteral narcotic analgesia in the early post-operative period.

Spica Casting in Pediatric Femur Fractures: Study of Single Leg Versus Double Leg Spica Casts
Femur FractureProspective randomized controlled trial comparing use of single leg spica with double leg spica casts in the treatment of pediatric femur fractures in children ages 2 through 6 years old.

Intramedullary Nailing of the Femur:Trochanteric vs Piriformis Starting Portals
Femur FractureThis project is designed to determine whether or not the trochanteric insertion portal will show any difference when compared with the piriformis fossa portal in terms of pain and strength of the hip abductor muscles, while allowing faster surgical fixation of the femur fracture.

A Prospective Study to Determine the Effectiveness of Reaming in Reducing Fat Emboli to the Lungs...
Diaphyseal Femur FractureThe purpose of the study is to see if there is a difference in the amount of fat droplets reaching the heart during surgery between the standard reamer currently used and a new reamer system which is expected to reduce the fat going into the blood, via an intraoperative echocardiography done through the food pipe.

ZNN Bactiguard Antegrade Femoral Nails PMCF Study
Femur FractureOsteotomyThis is a multicenter, prospective, Post-market Clinical Follow-up (PMCF) Study on the ZNN Bactiguard Antegrade Femoral Nails. The objective of this study is to collect data confirming the safety, performance, and clinical benefit of the study device and instrumentation when used for the temporary internal fixation and stabilization of femoral fractures and osteotomies. This is a CE-marked device already available on the market and the aim of the study is to comply with the post-market surveillance requirements.
