(1) With bilateral paralysis, bilateral plication improves the efficiency of the rib cage muscles in generating tidal volume.(2) The ability to perform this procedure without thoracotomy minimized his hospital stay and recovery time while not compromising the integrity of the plication .(3) Recently, we have begun to perform arthroscopic capsular plication in patients with significant capsule redundancy and laxity.(4) A technique has been described for arthroscopic plication of the rotator interval, but this was not used in our series of patients.(5) They are especially characteristic of many temperate trees where plication occurs between secondary veins before formation of tertiary veins in the bud.(6) Surgical therapy in the form of diaphragmatic plication is often reluctantly considered because of the potential morbidity and disability associated with thoracotomy.(7) Our patients who did not undergo bilateral plication showed a similar pattern.(8) A small minority of the Atrypacea have smooth shells, others being rather finely costate or having medium to coarse plications .(9) Strong radiating ribs are common in this group, and there are generally very strong plications or accordion like folds on the sulcus (the long middle section) of the shell.(10) Cyrtospirifer u2018sinensisu2019 differs from C. placitus by its flat ventral interarea and smaller number of sinal plications .(11) In some specimens of this species the shell plications may be grooved (divided by two grooves) due to abrasion of the shell, as first noted by Fenton and Fenton.(12) Some species of Tongzithyris have one to two pairs of plications .(13) Some shells develop up to two lateral sinal plications, but in most lateral sinal plications are lacking.(14) The shell possesses a sulcus on the ventral valve and a corresponding fold on the dorsal valve and several weak plications on flanks.(15) Many of these forms had high cardinal areas and coarse plications , although others were much more like conventional spiriferids.(16) Micro-pustules, both in grooves and on plications , are the most common type of micro-ornament.
