The advent of internal fixation with bone plates and screws represents a tremendous advancement in the methods of fracture fixation. During this era, the emphasis was on anatomic reconstruction and rigid internal fixation. Although these principles are applicable to a great number of fractures, not all can be treated in this manner. In fact, the disruption of the soft tissue envelope required t...

BACKGROUND The deltoid splitting approach has recently been widely adopted to facilitate less invasive procedures for proximal humerus fractures. However, there are still concerns regarding its effectiveness in aging people and in cases involving complex fractures. This study was conducted to evaluate the efficacy of a proximal humeral locking plate using the anterolateral deltoid splitting app...

The author reports the case of a 30-year-old female patient with bilateral atrophic non-union of the clavicle; the latter both healed after internal fixation with a locking compression plate fixed on the anteroinferior aspect of the clavicle, combined with autologous cancellous bone grafting. The advantages of the anteroinferior positioning of the plate on the clavicle are presented.

In this work-in-progress we report on a new approach to obtaining stable locking-free discretizations of the Reissner–Mindlin plate model. For a plate of thickness t with midplane section Ω ⊂ R the clamped Reissner–Mindlin plate model determines ω , the transverse displacement of the midplane, and φ , the rotation of fibers normal to the midplane, as the unique minimizer over H̊1(Ω)× H̊(Ω) of the...

Distal diametaphyseal tibia fracture though requires operative treatment is difficult to manage. Conventional osteosynthesis is not suitable because distal tibia is subcutaneous bone with poor vascularity. Closed reduction and minimally invasive plate osteosynthesis (MIPO) with locking compression plate (LCP) has emerged as an alternative treatment option because it respects biology of distal t...

OBJECTIVE The purpose of this study was to compare the biomechanical behavior of using two versus three locking screws per bone segment in a cadaveric humerus fracture gap model. METHODS Six matched pairs of elderly osteoporotic fresh-frozen human cadaveric humerii were used. An eight-hole locking compression plate was placed posteriorly on the humeral shaft and secured with either four or si...

A case is presented of a 78-year-old woman who sustained a re-fracture of the distal radius after initial fixation with a volar locking plate. The fracture was located in the mid-portion of the volar plate with palmar apex bending of the plate and signs of median nerve compression. A successful closed reduction was performed without hardware failure. The fracture united uneventfully.

BACKGROUND Angle-stable locking plates have improved the surgical management of fractures. However, locking implants are costly and removal can be difficult. The aim of this in vitro study was to evaluate the biomechanical performance of a newly proposed crossed-screw concept ("Fence") utilizing conventional (non-locked) implants in comparison to conventional LC-DCP (limited contact dynamic com...

Background Fixation of proximal chevron metatarsal osteotomy has been accomplished using K-wires traditionally and with a locking plate recently. However, both methods have many disadvantages. Hence, we developed an intramedullary fixation technique using headless cannulated screws and conducted a biomechanical study to evaluate the superiority of the technique to K-wire and locking plate fixat...
