A further understanding of morphological characteristics of the GT fragments may help explore new fixation devices. This study aimed to determine the fracture line morphology of the GT fragment of Neer three\u2010 or four\u2010part PHF and analyze the location relationship between the locking plate and the GT fragment.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>Seventy\u2010one three\u2010dimensional computed tomography scans of Neer three\u2010 and four\u2010part PHF were retrospectively reviewed between January 2014 and June 2019. Fracture fragments were reconstructed and virtually reduced in the Mimics software, and fracture lines of GT fragments were depicted on a humerus template in the 3\u2010matic software and then were superimposed altogether. The common sites of the GT fracture were identified, and the location relationship between the locking plate and GT fragments was analyzed in a computer\u2010simulated scenario.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The fracture line morphology of GT fragments was similar between Neer three\u2010 and four\u2010part PHF. The overall morphology of GT fragments was in a fan shape, which could be summarized as anterior, superior, posterior, and middle lines. Of these, we identified 51 split and 29 avulsion type GT fragments based on the Mutch classification, and they could occur simultaneously in a PHF. The overall morphology of split type fragments was in a fan shape, and avulsion type fragments showed a quite distinguishable distribution pattern. A GT fragment could be classified as anterior\u2010split, posterior\u2010split, complete\u2010split, anterior \u2010avulsion, and posterior\u2010avulsion type based on its morphology and location. The median percentage of fragment area covered by the plate was 32.3% in all of the fragments, and it was 69.4%, 23.0%, 37.2%, 21.8%, 0.0% in anterior\u2010split, posterior\u2010split, complete\u2010split, anterior\u2010avulsion, and posterior\u2010avulsion type GT fragments. We defined the posterior\u2010split, anterior\u2010avulsion, and posterior\u2010avulsion type GT fragments as the risky GT fragments, and they occurred in 43 (60.6%) Neer three\u2010 and four\u2010part PHFs.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>The fracture line morphology of GT fragments of Neer three\u2010 and four\u2010part PHF was in a fan shape.
