We propose a previously unrecognized variant of femoral neck fracture in which the fracture plane is vertical (Pauwels\u2009\u2265\u200990\u00b0) and lacks any Gotfried-positive cortical contact, a configuration we designate \u201creverse-obliquity femoral neck fracture\u201d (ROFNF). This report describes two cases of ROFNF and their respective therapeutic strategies.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Case report<\/jats:title>\n                    <jats:p>The index patient was a 56-year-old woman who sustained a Pauwels-III femoral neck fracture (95\u00b0) after slipping while playing table tennis. The second patient, a 45-year-old male, sustained a right femoral neck fracture (Pauwels III, 90\u00b0) during an electric vehicle rollover. Lumbar epidural anesthesia was administered supine on a fluoroscopy-compatible table for both cases. Following unsuccessful closed anatomical reduction, an anterior hip approach was utilized for open reduction. Fixation consisted of three 7.3\u2005mm cannulated screws supplemented by a medial buttress plate; radiographs at 8\u20139 months confirmed uneventful union in both patients.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>We were unable to find any prior description of a femoral-neck fracture whose inclination reaches or exceeds 90\u00b0 while also failing every Gotfried cortical-support criterion. In the two patients presented, closed manipulation could not restore a stable reduction; instead, an anterior approach with open reduction and a screw-plus-medial-buttress construct produced solid union.<\/jats:p>\n
