下颌骨髁状突骨折仍占下颌骨骨折的很大比例，髁状突下骨折的切开复位和坚强内固定已成为这种情况的标准治疗方法。对这种方法的偏好取决于在该领域中取得的相当大的技术进步，特别是在硬件开发方面（例如，三维解剖学特定形状和生物力学稳定的锁定髁下钢板系统），以及对骨折愈合的骨生物学和骨生理学的更好理解。然而，在本病例中，尽管应用了机械上足够坚硬的锁定接骨板和解剖学上精确的骨折复位，但仍无法避免一名68岁男性患者在下颌骨髁下骨折开放治疗后发生意外疲劳接骨板骨折的术后并发症。这种不寻常的情况下，强调需要进一步的骨生理生物学研究和可能的修改硬件系统的生物力学复杂的性质，下颌骨髁突下骨折手术治疗。
Fractures of the mandibular condyle still account for a significant proportion of all mandibular fractures, and open reduction and internal rigid fixation of subcondylar fractures has become the standard treatment for this condition. The preference for this approach rests on the considerable technical progress made in this domain, especially in hardware development (e.g., three-dimensional anatomically specifically shaped and biomechanically stable locking subcondylar plate systems), as well as on an improved understanding of the osteobiology and osteophysiology of fracture healing. However, in the present case, the postoperative complication of unexpected fatigue plate fracture in a 68-year-old male patient after open treatment of a subcondylar fracture of the mandible could not be averted despite application of a mechanically stiff enough locking plate and anatomically accurate fracture reduction. This unusual case highlights the need for further osteophysiobiological research and for possible modification of the hardware system in view of the biomechanically complex nature of mandibular subcondylar fracture surgical treatment.
