Biomechanical Stability of a Fixed-Angle Volar Plate Versus Fragment-Specific Fixation System: Cyclic Testing in a C2-Type Distal Radius Cadaver Fracture Model

A Biomechanical Comparison of Volar Locked Plating of Intra-Articular Distal Radius Fractures: Use of 4 Versus 7 Screws for Distal Fixation

“…Another study compared the use of volar locked plating and fragment-specific fixation using the same AO C2 fracture model as in the current study with cyclical loading. 10 In that study, fragment-specific fixation provided more stability for the lunate facet fracture fragment with regard to initial and final stiffness but not failure load. Those authors thought that 2 points of fixation for the scaphoid and lunate facet fracture fragments were adequate for early rehabilitation whether using volar locked plating or fragment-specific fixation.…”

“…We modeled testing after a previous study performed by Taylor et al,10 with modifications to this model as described below.…”

Osteotomy of dorsally displaced malunited fractures of the distal radius: No loss of radiographic correction during healing with a minimally invasive fixation technique and an injectable bone substitute

“…The fixation material chosen appears to be sufficiently stable and the rate of hydroxyapatite degradation is acceptable. Without being bulky, the TriMed system is more rigid than pins alone and achieves the same fixation strength as a volar angle stable plate in cadaver studies (Taylor et al 2006). In the failed case, the shortest 3-hole radial pin plate (RPP) was used and we therefore use the 5-hole RPP at present as the minimal length.…”

Biomechanical Comparison of Double-Row Locking Plates Versus Single- and Double-Row Non-Locking Plates in a Comminuted Metacarpal Fracture Model

“…17 The double-row plates are shorter, and their configuration was thought to provide added stability similar to the 90-90 double-plate fixation construct that is often used in complex and severely comminuted distal humerus and distal radius fractures. 18,19 This finding may eventually lead to less invasive procedures with shorter incisions, limited soft tissue dissection, and decreased scarring and soft tissue complications postoperatively. The complications of tendon irritation, tendon rupture, finger stiffness, and plate removal may therefore be decreased in theory with the use of these shorter plates.…”
