This study compares the functional capabilities of different metacarpal fixation constructs under physiological loadings in an attempt to identify the optimal construct rather than the strongest one. One hundred and twenty-six preserved human metacarpals were mechanically tested after oblique osteotomies and internal fixation. Maximum load to failure, average structural rigidity, and energ...

Background: Displaced fractures of radius and ulna bones in adults are usually treated with open reduction and internal fixation. The purpose of this research was to access functional outcome of these fractures. Materials and Methods: In this research 52 Patients who underwent ORIF with DCP 3.5 in past 5 years were investigated. Post-operation protocol was one week immobilization and then acti...

Failure of internal fixation following treatment of a fracture or fracture nonunion presents a challenging clinical situation. In certain cases, Ilizarov external fixation may be the preferred method to treat bony injuries that have failed to unite following one or more attempts at internal fixation. This paper reviews the modes of failure following internal fixation, revision internal fixation...

background: trans-scaphoid perilunate fracture-dislocation and perilunate dislocations are among uncommon injuries, most commonly seen in young patients due to high energy trauma. the treatment can be achieved either surgically by open reduc tion and internal fixation or closed reduction and casting.   methods: to compare surgical versus non-operative results of treatment of trans-scaphoid peri...

background:  clavicle fractures are common and usually heal without complications. in this study, we evaluated the outcomes of non-operative versus operative management of displaced fractures.   methods:  in a prospective clinical trial study, sixty-five patients with displaced clavicle mid-shaft fractures were nonrandomly divided in two treatment groups. the first group underwent non-operative...

Internal consistency reliability is the degree of correlation between a scale's items. Internal consistency is calculated by Kuder-Richardson's formula 20 for dichotomous choices and Cronbach's alpha for polytomous items. 0.70 to 0.90 internal consistency is acceptable. 5-25 participants are needed for each item when computing the internal consistency of a twenty-item scale. Internal consistenc...

BACKGROUND AND PURPOSE In unstable distal radial fractures that are impossible to reduce or to maintain in reduced position, the treatment of choice is operation. The type of operation and the choice of implant, however, is a matter of discussion. Our aim was to investigate whether open reduction and internal fixation would produce a better result than traditional external fixation. METHODS 5...

OBJECTIVE To assess improvements in fixation stability when a hinged unilateral external fixator is used to supplement compromised internal fixation for distal humerus fractures. METHODS Removing a 1-cm section of the distal humerus in cadaveric whole-arm specimens created a comminuted distal humerus fracture model (AO type 13-A3). Fixation was then performed using different constructs repres...

Background To compare the salvage rate and complication between internal fixation and external fixation in patients with small bone defects caused by chronic infectious osteomyelitis debridement. Methods 125 patients with chronic infectious osteomyelitis of tibia fracture who underwent multiple irrigation, debridement procedure, and local/systemic antibiotics were enrolled. Bone defects, whic...
