The purpose of this study was to evaluate the results of our correction osteotomies of distal radial malunions without a bone graft. Eleven consecutive patients (mean age 52 years, range 18–71) were treated. A dorsal approach was utilised to perform an opening-wedge osteotomy which then was stabilised with two dorsal columnar plates without filling the osteotomy gap. All patients went on to radiographic union with a filling of the osteotomy gap within a mean period of 3 months (range 2–6 months). All patients had satisfactory results in terms of function and pain. Correction osteotomy and stabilisation with bicolumnar locked plate fixation without a bone graft provides sufficient stability to allow the highly vascularised metaphysis to heal. In patients without risk factors predisposing to non-union, this procedure is safe and feasible. 相似文献

Jones type fifth metatarsal fractures pose a challenge to the foot and ankle surgeon, given documented high nonunion rates as well as high complication rates including hardware prominence, nerve injury, and screw breakage for existing treatment modalities including screw and plantar plate fixation. We call for the design of innovative Jones-fracture specific implants which contour to the natural curve of the fifth metatarsal. Future research should aim to expand upon existing literature for Jones fracture fixation and evaluate efficacy of novel implants which are designed to address unacceptably high complication rates for existing treatment modalities. 相似文献

PURPOSE: To establish the accuracy, precision, and clinical feasibility of a novel technique of computer-assisted distal radius osteotomy for the correction of symptomatic distal radius malunion. METHODS: Six patients underwent a computer-assisted distal radius osteotomy and were followed-up for an average of 25 months. Objective radiographic measurements and functional outcomes, as measured by clinical examination including grip strength and range of motion, and Disability of the Arm, Shoulder and Hand (DASH) questionnaires, were used. RESULTS: The mean radiographic parameters included an increase of radial inclination to 21 degrees from 12 degrees (normal, 23 degrees ). Dorsal and volar tilt (malunion) were corrected to 9 degrees from -30 degrees and 21 degrees, respectively (normal, 10 degrees ). Ulnar variance was corrected to 1.9 mm from 7.5 mm (normal, +1.5 mm). Normal is defined as the average of the contralateral limb radiographs. The mean clinical outcome measures at an average of 25 months included a DASH global score of 14, a DASH individual item average score of 1.6, and an average affected side grip strength of 79% when compared with the unaffected side. CONCLUSIONS: The results of the computer-assisted technique were comparable with published results of traditional non-computer-assisted opening wedge osteotomy techniques. This technique allows a surgeon to accurately and precisely recognize and correct 3-dimensional deformities of the distal radius including axial malalignment (supination). The technique has the added benefit of reducing radiation exposure to the patient and surgical team because fluoroscopy is not used during the procedure. Additional benefits of the computer-assisted technique include the ability to perform multiple surgical simulations to optimize the alignment plan, and it serves as an excellent teaching tool for less-experienced surgeons. 相似文献

Summary This retrospective consecutive clinical series describes our satisfactory experience with reamed intramedullary femoral nailing in the treatment of nonunions, axial or rotational deformities as well as length discrepancies following the primary treatment of femoral shaft fractures. 31 patients (32 fractures) treated at our institution from 1992 to 1997 were reviewed for age, gender, cause of injury, type of femur fracture, primary treatment, indication for secondary nailing, operative procedure, complications, need for additional procedures and time for consolidation. 3 patients were lost for follow-up, leaving 28 patients (29 fractures) for evaluation. The average follow-up was 79 weeks (range 24 to 192). The indications for secondary nailing were: 18 nonunions, 7 rotational or axial deformities, 4 length discrepancies. Consolidation was achieved in 25 patients (26 fractures) at an average time of 38 weeks (range 12 to 104). Nonunion was recorded in 3 patients. They were treated successfully with an additional procedure (one exchange intramedullary nailing and two autologous bone grafts). The reamed intramedullary interlocking nail offers many advantages, especially a good initial and middle term stability which is important in case of a slow process of consolidation. By the treatment of atrophic and long lasting nonunion, simultaneous bone grafting seems to be indicated. We conclude that interlocking reamed femoral nailing is a safe treatment option for nonunions and malunions following primary treatment of femoral shaft fractures, resulting in successful union without additional procedure in 26 of 29 fractures in this series. 相似文献

Fractures of the clavicle are common and have been typically addressed to nonoperative treatment. Favorable results, which
predominantly were achieved in the young and adolescents, were supposed to be usual in midshaft clavicular fractures. However,
in the presence of comminution or complete displacement, especially when occurring in females or elderly patients, there is
a marked risk of nonunion, malunion, and poor outcome. Thus, many authors prefer primary surgical stabilization, when risk
factors add up. Plate fixation and intramedullary stabilization seem to be equally favored. Though, indications for operative
management remain controversial. Further prospective randomized comparative clinical trials are necessary for a well-founded
risk-benefit analysis. 相似文献
