Active clinical trials for "Fractures, Bone"

To investigate the assumption that reversed shoulder prosthetic replacement will give a better functional outcome compared to open reduction and internal fixation with an angular stable plate in displaced proximal humeral fractures. Short name: The DelPhi trial.

BACKGROUND: Fractures of the distal radius are common and account for an estimated 17% of all fractures diagnosed. Two-thirds of these fractures are displaced and require reduction. Although distal radius fractures are considered to be relatively harmless, inadequate treatment may result in impaired function of the wrist. The consequences of post-traumatic loss of function are comprehensive, both on an individual and a social level, and have long been underestimated. Despite the substantial implications, no evidence-based treatment method yet exists. Good results have been described both in patients treated conservatively and surgically. Nevertheless, 60% of all fractures redislocate after conservative treatment at which point surgical reduction and fixation is the treatment of choice. Recently, the use of volar locking plates has become more popular. This type of osteosynthesis employs a volar approach to the wrist and provides immediate stable fixation of the reduced fracture. This stability allows for early mobilisation and may therefore result in an improved regain of function. The aim of this study is to compare the functional outcome following surgical reduction and fixation with a volar locking plate with the functional outcome following closed reduction and plaster immobilisation at one year follow-up in patients with displaced extra-articular distal radius fractures. DESIGN: This single blinded randomised controlled trial will randomise between open reduction and internal fixation with a volar locking plate (intervention group) and closed reduction followed by plaster immobilisation (control group). The study population will consist of all consecutive adult patients who are diagnosed with a displaced extra-articular distal radius fracture which has been adequately reduced at the Emergency Department. The primary outcome (functional outcome) will be assessed by means of the Disability Arm Shoulder Hand Score (DASH). Since the treatment allocated involves a surgical procedure, randomisation status will not be blinded. However, the researcher assessing the outcome at one year will be unaware of the treatment allocation. In total, 90 patients will be included in this trial which will be conducted in the Academic Medical Centre Amsterdam and its partners of the regional trauma care network.

The purpose of this study is to assess the differences between two different types of devices for the treatment of unstable pertrochanteric hip fractures. The hypothesis of this study is, that patients who are treated with the proximal femoral Nail Antirotation (PFNA) have a better outcome and lower complication rates than patients treated with the Gamma Nail (GN3).

There are approximately 250,000 hip fractures in the US every year, and intertrochanteric (IT) fractures (fractures that occur just below the femoral head) account for nearly half of these fractures. The use of intramedullary (IM) nails for fixation of IT femur fractures has become a well-accepted and increasingly more common procedure among orthopaedic traumatologists, and is standard of care at our institution. While advancements in intramedullary nail fixation have made it a relatively efficient procedure, the placement of the lag screw into the femoral head still remains a challenging step in the procedure. Inaccurate placement can lead to screw cut-out, one of the most commonly reported complications with IM nail fixation. Previous work has shown that the lag screw position is an important factor in reducing screw cut-out. This step of the procedure can be time demanding and often requires several intraoperative radiographs for accurate placement. Recently developed computer-assisted navigation systems provide surgeons with the ability to track screw placement in real-time. This could allow for improved screw placement and potentially reduce radiation exposure to the patient and surgeon. To date, the potential advantages of computer-assisted navigation have not been examined. The primary objective of this study is to examine whether the use of Stryker's ADAPT computer-assisted navigation for Gamma nail fixation can result in improved lag screw placement. The secondary objective is to examine whether the use of the ADAPT for Gamma nail fixation can reduce intraoperative radiation exposure.Our hypothesis is that there is a difference in the lag screw placement (i.e. tip to apex distance measurement) between procedures using the ADAPT system versus the conventional technique for Gamma nail fixation. Additionally, we hypothesize that there is a difference in radiation exposure (i.e. fluoroscopy time) between procedures using the ADAPT system versus the conventional technique for Gamma nail fixation.

Tibial shaft fracture is one of the most common fractures in children and adolescents. It encompasses approximately 15 % of all long-bone fractures and is third behind only fractures of the femur and both bones of the forearm. (2). Although most authorities agree that closed tibial shaft fractures are best treated by immobilization in a long-leg cast, there is no clear consensus as to when to allow weight bearing on the injured extremity. While most recent articles have recommended long-leg casts with the knee bent in flexion of 30-60 degrees to preclude weight-bearing(1,2,3,4), other authors have recommended much less flexion, 0-5 degrees, to encourage early weight bearing.(5). The purpose of this randomized controlled prospective study is to determine if the position of immobilization of the knee influences the rate of healing, delayed union, and nonunion As well, we will assess if the type of immobilization affects the function of the patient during the period of treatment using the Activities Scale for Kids - Performance (ASK-P) child self-report musculoskeletal outcome measure . A minimum of 36 patients in each group for a total of 72 patients between 4 and 14 years of age (open physis) with closed fractures of the tibia, with or without fracture of the fibula, will be included in the study

Metacarpal V fractures are injuries of the upper extremities. They occur frequently, primarily in young adults.These fractures are caused by falling on the fist, sports accidents and direct or indirect forces. Surgical intervention is necessary for fractures with a strong palmar angulation of the metacarpal bone or rotational deformity of the small finger. Due to the absence of guideline recommendations decisions about therapy are made taking into account logistical aspects, available hardware, individual expertise and preferences. The objective of the study is to compare the advantages and disadvantages of single versus double Kirschner wires for intramedullary fixation of metacarpal V fractures in order to standardize national therapy procedures. Primary hypothesis: In the surgical therapy of the dislocated and/or rotational deformed metacarpal V neck fracture, osteosynthesis with a single Kirschner wire is not inferior to osteosynthesis with a double Kirschner wire with regard to the functional outcome after 6 month, as measured with the Disabilities of the Arm, Shoulder and Hands Score (DASH).

Toddler's fractures of the tibia are by definition non-displaced and of a stable pattern. Children have thickened periosteum compared with adults, which therefore may impart stability to the fracture without the need for additional immobilization. The goal of the study is to evaluate whether or not there is a difference in children treated with and without cast immobilization in regards to time to ambulation; perceived pain; difficulty in dressing & bathing; radiographic displacement or angulation; and time missed from work or daycare. Our null hypothesis is that there will be no difference in clinical or radiographic outcomes between the groups.

This study will compare non-operative treatment of displaced midshaft collarbone fractures with operative treatment using a precontoured titanium plate and screws. The study hypothesis is that operation will provide better pain relief, faster return to activities, better function of the involved upper limb, and lower the risk of a non healing fracture (non union).

Both simple decompression and anterior transposition of the elbow nerve (ulnar nerve) for acute displaced fractures of the elbow (distal humerus) treated with plate fixation are currently used by surgeons. We want to examine which treatment will overall give better results in regards to arm function and residual pain.

Each year, hip fracture, an injury that can impair independence and quality of life, occurs in about 280,000 Americans and 36,000 Canadians. The annual healthcare costs associated with this injury are expected to soon reach $9.8 billion in the United States and $650 million in Canada. It is important to have in place optimal practice guidelines for the surgical handling of this injury. One type of hip fracture, called a femoral neck fracture, is often treated with a surgical procedure called internal fixation. When performing internal fixation, most orthopaedic surgeons favor using multiple small diameter screws over using a single large diameter screw with a sliding plate. However, use of the sliding hip screw might in fact result in fewer complications after surgery and reduce the need for a second surgery, called a revision surgery. This study will compare the two different surgical procedures to determine which one results in better outcomes after surgery.
