“…Especially palmar angulation has been intensively debated. While many use an angulation threshold of 40° or even 60° (Cepni et al., 2016; Chen et al., 2020; Eldridge and Apau, 2015; Elmowafy et al., 2018; Facca et al., 2010; Fujitani et al., 2012; Kaynak et al., 2019; Kim and Kim, 2015; Ozturk et al., 2008; Pogliacomi et al., 2017; Potenza et al., 2012; Poumellec and Dreant, 2017; Rhee et al., 2012; Sadiq and Hussain, 2019; She and Xu, 2017), still a maximal angulation of 30° has been the guideline in many recent studies (Amsallem et al., 2018; Galal and Safwat, 2017; Kim and Kim, 2015; Surke et al., 2020; Tank et al., 2018; Winter et al., 2007; Wong et al., 2015). Rotational deformity must also be taken in account, although this rarely is a problem with neck fractures of the fifth metacarpal.…”
