Experimental trial on surgical treatment for transverse fractures of the proximal phalanx: technique using intramedullary conical compression screw versus lateral compression plate☆
نویسندگان
چکیده
OBJECTIVE To compare the mechanical parameters between two methods for stabilization through compression: 1.5 mm axial compression plate versus conical compression screw used as an intramedullary tutor. METHODS Polyurethane models (Sawbone(®)) that simulated transverse fractures of the proximal phalanx were used. The models were divided into three groups: lateral plate, conical screw and no implant. RESULTS Greater force was needed to result in fatigue in the synthesis using an intramedullary plate. Thus, this model was proven to be mechanically superior to the model with the lateral plate. CONCLUSION Stabilization using the Acutrak(®) screw for treating fractures in the model used in this trial presents mechanical results that are statistically significantly superior to those from the axial compression technique using the lateral plate (Aptus Hand(®)).

Objective: Fractures of metacarpals and phalanges are very common fractures, and there are a lot of treatment modalities. The purpose of the study was to describe the technique of percutaneous fixation of phalangeal fractures using a cannulated compression screw fixation system and its results. Methods: We conducted a prospective clinical study on 43 patients with different types of phalangeal ...
متن کاملPlantar Plating for the Treatment of Proximal Fifth Metatarsal Fractures in Elite Athletes.
Proximal fifth metatarsal fractures, zones II and III, are commonly treated surgically, especially in elite athletes. Intramedullary screw fixation remains the most used construct despite nonunion and refracture. High tensile forces on the plantar-lateral aspect of the fifth metatarsal are difficult to control, and intramedullary screw fixation depends on ideal screw position, length, and width...
متن کاملThe functional results of tibial shaft fractures treated with intramedullary nail compressed by proximal tube.
Nailing of tibial shaft fractures is considered the gold standard surgical method by many surgeons. The aim of this retrospective study was to investigate and compare the clinical outcome of tibial shaft fractures treated with intramedullary nails compressed by proximal tube and conventional intramedullary interlocking nails. Fifty-seven patients with tibial shaft fractures, treated with intram...
متن کاملFractures of the proximal phalanx and metacarpals in the hand: preferred methods of stabilization.
Treatment of fractures of the proximal phalanx and metacarpals is based on the presentation of the fracture, degree of displacement, and difficulty in maintaining fracture reduction. A wide array of treatment options exists for the variation in fracture patterns observed. Inherently stable fractures do not require surgical treatment; all other fractures should be considered for additional stabi...
