Review Case ReportsAnnular ligament reconstruction in chronic Monteggia fracture-dislocations in the adult population: indications and surgical technique.
Chronic Monteggia fracture is defined as dislocation of the radial head that is still present 4 weeks after injury. The cause may reside in residual ulnar deformity after internal fixation, in failure of annular ligament healing, or both. This situation may lead to elbow pain, decreased motion, neurologic problems and valgus deformity. ⋯ ALR has been advocated to address radial head instability both combined with ulna osteotomy and as a single procedure, with several surgical techniques described and controversial results reported. A modified Bell Tawse surgical technique resulted to be effective in the presented case. ALR seems to be indicated in chronic Monteggia fractures with normal bony alignment, without conclusive evidence on a preferable surgical technique.

Comparative StudyComparison of CFR-PEEK and conventional titanium locking plates for proximal humeral fractures: a retrospective controlled study of patient outcomes.
Metal plates are the fixation devices used most frequently to proximal humeral fractures (PHFs). However, in recent years carbon fiber-reinforced polyetheretherketone (CFR-PEEK) plates have become increasingly common. This study compares the clinical and radiographic outcomes of 42 Neer three- and four-part PHFs treated with CFR-PEEK or metal (titanium) plates. ⋯ CFR-PEEK plates provide a viable alternative to conventional titanium plates in PHFs, ensuring similar clinical outcomes and a lower rate of tuberosity resorption, but they involve higher stress shielding under the plate.
