Comminuted fractures of phalanx are challenging to reduce properly. Commonly, the fragments are distracted by various ligaments as well as flexor and extensor tendons. Splints, skeletal traction, Kirschner wire, plate and screws, and cerclage wires have all been used to manage such fractures. Among these, the cerclage wires are able to effectively contain the distracting forces and maintain a proper concentric reduction of the hollow tube structure of phalangeal bones. The resulting tissue-hardware construct is stable and allows early rehabilitation. Despite the obvious mechanical advantages, cerclage wiring of phalangeal fractures require open incisions. Inevitably, this approach leads to periosteal stripping, upon which the distracting forces exaggerate the displacement of comminuted fragments and the blood supply to the injured bone is compromised. To overcome the disadvantages of open approach, the authors have devised a minimally invasive technique in which the cerclage wire is introduced using a hypodermic needle for fractures of the proximal phalanx and distal phalanx base.
指骨粉碎性骨折的正确复位具有挑战性。通常,骨折碎片会受到各种韧带以及屈肌腱和伸肌腱的牵拉。夹板、骨牵引、克氏针、钢板螺钉和环扎钢丝都曾用于治疗此类骨折。其中,环扎钢丝能够有效抑制牵拉力,维持指骨空心管状结构的正确同心复位。由此形成的组织 - 硬件结构稳定,允许早期康复。尽管环扎钢丝具有明显的力学优势,但指骨骨折的环扎术需要切开。这种方法不可避免地会导致骨膜剥离,在此情况下,牵拉力会使粉碎性骨折碎片的移位加剧,并且受损骨骼的血供也会受到影响。为克服开放手术方法的缺点,作者设计了一种微创技术,即使用皮下注射针为近节指骨和远节指骨基底骨折引入环扎钢丝。
