Kim SS, et al. - The clinical outcomes of PFNA-II, one of the commonly used fixation devices for intertrochanteric fractures, were examined. Further, researchers determined the association of clinical results with the extent of proximal nail protrusion. They assessed 315 cases who underwent internal fixation using PFNA-II between September 2010 and June 2018 among intertrochanteric fracture patients aged over 65 years; of these, 86 patients with an ability to communicate clearly and a minimum follow-up of 6 months were retrospectively reviewed. Thirty of 86 patients (34.9%) comprised the protrusion group and 56 (65.1%) comprised the non-protrusion group. Observations suggest the frequent occurrence of nail protrusion over the greater trochanter area after the surgical treatment of intertrochanteric fracture using PFNA-II. When the nail protruded into the greater trochanter, statistically significantly high number of patients complained of pain. A modification to the PFNA-II including further shortening of the proximal nail end suitable for the Asian population is recommended for achieving better clinical results in the fixation of intertrochanteric fractures.
