The second-generation cast-brace system offers some advantages over previous systems of cast-brace treatment for fractures of the femur. Because the thigh section is adjustable, loosening of the cast-brace is not a problem. The device can be applied earlier and need not be reapplied when the girth of the thigh is reduced. Using a roller traction system, the cast-brace can also be used initially for traction and suspension without the complexity of traditional systems. With the use of commercially available plastic knee joints, special skills in alignment of the joints are not necessary, and no specially trained personnel need be on hand. The lightweight thigh section coupled to custom-fit plaster leg section, with the foot and ankle free, are less bulky than a totally plaster cast-brace with metal side joints. Walking may be begun earlier with the device, and in-patient hospital time is reduced. However, this system requires a high level of patient cooperation in that the patient is free to adjust the system himself and, therefore, the system may not be safe for application in all settings.
第二代铸型支具系统相较于先前用于股骨骨折的铸型支具治疗系统具有一些优势。由于大腿部分是可调节的，铸型支具松动不是问题。该装置可更早应用，并且当大腿周长减小时无需重新应用。使用滚轮牵引系统，铸型支具最初也可用于牵引和悬吊，而无需传统系统的复杂性。通过使用市售塑料膝关节，无需特殊的关节对线技能，也无需有经过专门培训的人员在场。轻质的大腿部分与定制的石膏腿部部分相连，足部和踝部自由，比带有金属侧关节的全石膏铸型支具体积更小。使用该装置可更早开始行走，住院时间也会减少。然而，该系统需要患者高度配合，因为患者可自行调节系统，因此在所有情况下应用该系统可能并不安全。
