NS = nonsignificant; ROM = range of motion.
↵* Functional outcome measures include lower extremity measure, Harris hip score, Lysholm score, Lysholm and Tegner score, Western Ontario and McMaster Universities Arthritis Index, Merle d’Aubigne and Postel, knee injury and osteoarthritis outcome score and hip dysfunction and osteoarthritis outcome score.
↵† Other medical complications include pulmonary embolism, fat embolus syndrome, deep venous thrombosis, postoperative hematoma, hemarthrosis, infection, hyperbilirubinemia and pneumonia.
↵‡ Favours greater trochanteric nailing.
