Active clinical trials for "Fractures, Bone"

The overall purpose of this study is to establish the utility of early mobilization in improving patient satisfaction following plate and screw fixation of wrist fractures. Subjects will have objective range of motion data collected and subjective survey data collected at 2 weeks, 6 weeks, 3 months, and 1 year after being randomized either to an early mobilization group that receives a removable wrist splint or a late mobilization group that is placed in a splint for 2 weeks post-operatively. The investigators expect that early wrist mobilization following locking plate fixation of wrist fractures will lead to an increase in postoperative patient satisfaction without a significant increase in complications.

To compare between buried k wires and miniplate in management of metacarpal fracture.

Clinical research during the last ten years has revealed that elderly patients with a displaced femoral neck fracture should be treated with arthroplasty instead of closed reduction of the fracture followed by internal fixation with pins or screws. Few clinical trials have addressed undisplaced or minimally displaced fractures of the femoral neck. These fractures have been associated with a good prognosis and likewise a good functional outcome. However, recent articles present far less favorable results, with high re-operation rates (10-15%), reduced function, and pain on walking after internal fixation. Indirect comparing studies, suggest that hemiarthroplasty may yield better functional outcomes and lower re-operation rates. Approximately 20% of all femoral neck fractures in patients aged 70 years or older are minimally displaced or undisplaced. Hence the investigators call for a randomised controlled trial comparing pain, function, walking ability, quality of life, re-operation rates and complications after internal fixation versus hemiarthroplasty in patients aged 70 years and older.

The investigators hypothesized that mesenchymal stem cells can be isolated from fracture site, iliac crest, and tibial crest, and can be expanded to be used in the management of nonunion fracture.

The purpose of this study is to evaluate whether ultrasonography guidance compare with the simple radiography aids in determining the adequacy of distal radius fracture reduction.

The Alpes Maritimes county administration (France) equipped Nice University Hospital of a 0,2T low field MRI dedicated to distal articulations, devoted to research, installed in the medical imaging unit. The aim of our project is to study its interest in diagnosis of scaphoid fractures. Conventional medical care for patients being suspected to have a scaphoid fracture consists in performing a clinical examination and a radiographic check-up with at least 4 incidences, which 2 specific incidences for the scaphoid bone. Yet, this check up is sometimes defective, causing false positives unnecessary immobilisation and false negatives delays in patient medical care, increasing the risk of complication. Those diagnosis mistakes can bring serious consequences, from permanent partial inability, to professional reclassification. Alternative imaging exists, but is often irradiating, and never reaches the optimal specificity and sensitivity. MRI is totally safe, and allows to affirm or invalidate the diagnosis in almost 100% of cases. The problem is the lack of accessibility for emergency cases; therefore there is a great interest in validating the use of a MRI dedicated to distal articulations. The few studies that study costs of diagnosis strategies including MRI in scaphoid bone fractures diagnosis show a reduction of medical costs if this technique is used early. Our project represents an essential initial step in evaluating the impact of a low field MRI dedicated to peripheral articulations in diagnosis of scaphoid fractures. The next step will be a medico-economical study, since scaphoid fractures occur frequently. Finally, a new consensus for medical care of scaphoid fracture suspicions could be proposed.

Intra-articular fractures at the dorsal base of the distal phalanx of the hand are usually referred to as Mallet fractures. Treatment of Mallet fractures remains controversial. Although no differences in clinical results are reported between conservative treatment and operative treatment, operative treatment is suggested for fractures involving more than 30% of articular surface. There are many different operative techniques, all with specific disadvantages. The investigators hypothesis is that operative treatment of Mallet fractures with one Meniscus Arrow® has a better outcome than conservative treatment with a Mallet splint.

The purpose of this study is to compare hemiarthroplasty (HAP) with total hip arthroplasty (THA), performed by trained arthroplasty surgeons with the use of large femoral heads for the treatment of displaced femoral neck fractures in mobile independent elderly patients, to determine the impact of these surgical options on the short term functional outcomes and complication rates, namely dislocation and the need for further surgery. This is a single-blinded prospective randomized clinical trial comparing functional outcome and complication rates of 40 patients treated with all cemented THA to a control group of 40 patients treated with cemented bipolar HAP, in a 2 years followup. The primary endpoint is the Oxford hip score (OHS) at last followup as a measure of functional outcome. Secondary endpoints include the SF-36 score, walking distance and rates of postoperative dislocation, component loosening, need for revision and postoperative mortality.

The purpose of this study is to evaluate our experience in internal fixation of intracapsular femoral neck fractures with the Targon FN implant prospectively and retrospectively in terms of the outcomes and complications associated with the treatment.

There is increasing evidence that primary hemiarthroplasty is the treatment of choice for displaced femoral neck fractures in the elderly No definite conclusions have been made in regards to what kind of arthroplasty is favourable Cemented implants are associated with increased risk of perioperative cardiovascular incidents and increased mortality. Cementless implants are associated with increased postoperative pain and decreased walking ability. This study investigates the differences between one well-documented cemented femoral stem and one well-documented uncemented femoral stem. Previous studies have mostly used uncemented stems with different designs. Null hypothesis: No (less than 10 points) difference in HHS between groups at 1 year and 5 years
