The difference in altitude between the proximal limit of the femoral head and the tip of the greater trochanter--the articulotrochanteric distance (ATD)--was recorded in 312 patients with slipped capital femoral epiphysis and compared with that in normal hips. The ATD was markedly reduced after severe slipping, independent of the method of treatment. In mild or moderate slippings, the ATD differed with the method of treatment. The shortest ATD was seen after osteosynthesis with AO screws. Nonoperative treatment and osteosynthesis with the Johansson nail or Nyström pin caused a slight reduction of the ATD, while no reduction was seen after hook-pinning. These differences probably reflect various degrees of damage to the subcapital growth plate, which may result in leg length difference and abduction insufficiency.
记录了312例股骨头骨骺滑脱患者股骨头近端界限与大转子尖之间的高度差——关节转子间距（ATD），并与正常髋关节的该数值进行比较。严重滑脱后，ATD显著减小，与治疗方法无关。在轻度或中度滑脱中，ATD因治疗方法而异。采用AO螺钉进行骨合成后，ATD最短。非手术治疗以及采用约翰松钉或尼斯特伦针进行骨合成会使ATD略有减小，而采用钩钉固定后则未见减小。这些差异可能反映了股骨头下生长板不同程度的损伤，这可能导致腿长差异和外展功能不全。
