The treatment of unstable pelvic ring fractures, markedly comminuted and displaced acetabular fractures and combinations of these insults to the pelvis is an unsolved problem. Of all the previously described methods, external fixation has appeared to hold the most promise for certain pelvic bone injuries of major proportions which are accompanied by instability of the pelvic ring. Many of the external fixation devices of the past have not provided adequate stability. A modification of the Hoffmann external frame provides a simple method of treatment for unstable pelvic ring fractures that immediately permits the patient to move from bed to chair. Complex pelvic and central acetabular fractures also are responsive to treatment by extensive external frames. While this external skeletal fixation is superior to previously available devices, internal fixation is under consideration for stabilization of the posterior portion of the pelvic ring. A combination of internal and external fixation may also be advantageous for severely disrupted pelvic bones.
不稳定骨盆环骨折、明显粉碎性和移位性髋臼骨折以及这些骨盆损伤的组合的治疗是一个尚未解决的问题。在所有先前描述的方法中，外固定对于某些伴有骨盆环不稳定的严重骨盆骨损伤似乎最有前景。过去的许多外固定装置都没有提供足够的稳定性。对霍夫曼外固定架进行改良，为不稳定骨盆环骨折提供了一种简单的治疗方法，可使患者立即从床上转移到椅子上。复杂的骨盆和中央髋臼骨折对外固定架的广泛治疗也有反应。虽然这种外骨骼固定优于以前可用的装置，但正在考虑采用内固定来稳定骨盆环的后部。内固定和外固定相结合对于严重破碎的骨盆骨可能也有利。
