WitrynaHertel developed a binary classification system (12 subtypes) and demonstrated that some patterns have more risk to develop osteonecrosis. Hertel described the prevalence and the risk factors for Humeral head osteonecrosis after osteosynthesis using a Deltopectoral approach. WitrynaThe Neer four-segment classification system for proximal humerus fractures is shown. This diagram includes the valgus impacted four-part fracture (A) and the classic displaced four-part fracture (B). (Reprinted with permission from Neer CS 2nd. Displaced proximal humeral fractures.

Witryna1 paź 2024 · The proximal humerus consists of the humeral head, the greater and lesser tuberosities and the humeral shaft ( Figure 1 ). The humeral head is spheroidal in shape with a mean radius of curvature of 25 mm 5 and covered by articular cartilage.
Witryna1 lip 2013 · The HGLS classification is a reliable method of describing fractures of the proximal humerus. Given the similarities with the binary LEGO system, the HGLS system, to an extent, has been indirectly validated by the work of Hertel et al. 9 However, further validation testing in a clinical context is important before its wider acceptance. WitrynaProximal humerus fractures are common fractures often seen in older patients with osteoporotic bone following a ground-level fall on an outstretched arm.
