In this study the authors have endeavored to define more closely the distinct nature of the collateral and suspensory ligaments of the lesser metatarsophalangeal joints and to propose a mechanism through which the ligaments confer stability to the metatarsal head. The lesser metatarsal neck dorsal V-osteotomy is one surgical procedure that has the potential of disrupting the intracapsular ligaments, depending on the placement of the "V" cut. The angulation of the "V" cut redirects the capital fragment in the sagittal plane while maintaining stability in the transverse and frontal planes. The authors contend that the sagittal stability of the free capital fragment after a V-osteotomy is maintained, as well, by the attachment of the newly defined suspensory ligaments and the collateral ligaments of the metatarsophalangeal joint. Disruption of these ligaments, such as occurs when placing the apex of the V-osteotomy proximally, serves to increase the instability within the metatarsal head, ultimately leading to a potential increase in number of complications.
在本研究中，作者们致力于更精确地界定小趾跖趾关节侧副韧带和悬韧带的独特性质，并提出一种韧带赋予跖骨头稳定性的机制。小跖骨颈背侧V形截骨术是一种外科手术，根据“V”形切口的位置，有可能破坏关节囊内韧带。“V”形切口的角度在矢状面重新定向近端骨块，同时在横切面和额状面保持稳定性。作者们认为，V形截骨术后游离近端骨块的矢状面稳定性同样通过新定义的跖趾关节悬韧带和侧副韧带的附着得以维持。这些韧带的破坏，比如V形截骨术的顶点置于近端时所发生的情况，会增加跖骨头内的不稳定性，最终可能导致并发症数量增加。
