Metatarsophalangeal joint instability of the lesser toes is a common finding and a common cause of metatarsalgia. The clinical presentation can include swelling without digital deformity; however, often, this can progress to the development of coronal and transverse plane malalignment. In some cases, frank metatarsophalangeal joint dislocation can develop. The treatment regimen has historically focused on indirect surgical realignment using soft tissue release, soft tissue reefing, tendon transfers, and periarticular osteotomies. An improved understanding of the plantar plate has recently led to the development of a clinical staging system and surgical grading system of plantar plate attenuation. A dorsal surgical approach, using a Weil osteotomy, allows the surgeon to directly access and repair or advance the plantar plate to the base of the proximal phalanx. The addition of direct plantar plate repair could be a significant advancement in the reconstruction and realignment of metatarsophalangeal joint instability.
小趾跖趾关节不稳是一种常见表现,也是跖痛症的常见病因。临床表现可包括无趾畸形的肿胀;然而,这种情况常常会发展为冠状面和横断面的排列不齐。在某些情况下,会出现明显的跖趾关节脱位。以往的治疗方案主要侧重于通过软组织松解、软组织缩紧、肌腱转移和关节周围截骨术进行间接手术复位。最近,对跖板的进一步了解促使了跖板衰减的临床分期系统和手术分级系统的发展。采用韦尔截骨术的背侧手术入路,使外科医生能够直接进入并将跖板修复或推进至近节趾骨基部。直接修复跖板可能是跖趾关节不稳重建和复位方面的一项重大进展。
