Notwithstanding the generally known principles of therapy, indications can be enlarged by use of an annular fixator to cover the following applications: 1. stage fractures of the tibia, 2. stabilisation of fractures of polytraumatised patients with no need for anatomic reposition in the first place, 3. closed lower limb fractures with soft tissue lesions. Possible unlimited correction of primary and secondary dislocations without the need for transposition of Steinmann pins already implanted, compatibility with AO external fixation systems for supplementary use of annular fixator elements for possible management of secondary dislocations and variable placeability of pins or screws for subsequent wound debridement and muscle flap transposition are major advantages of the annular fixator. Results so far obtained from use of the annular fixator are described by clinical examples.
尽管有普遍已知的治疗原则，但通过使用环形固定器可扩大适应证，以涵盖以下应用：1. 胫骨阶段性骨折；2. 多处创伤患者骨折的固定，这些患者首先无需解剖复位；3. 伴有软组织损伤的下肢闭合性骨折。环形固定器的主要优点包括：无需移动已植入的斯氏针即可对原发和继发脱位进行可能的无限矫正，与AO外固定系统兼容，以便在可能处理继发脱位时补充使用环形固定器元件，以及针或螺钉的可变放置性，便于后续伤口清创和肌皮瓣转移。本文通过临床实例描述了迄今为止使用环形固定器所获得的结果。
