Brachymetatarsia is a condition in which a metatarsal bone does not grow out to full length. This is caused by premature physeal closure. The proximal phalanx associated with the shortened metatarsal helps achieve the natural parabola of the foot. A hypoplastic proximal phalanx is a common finding in patients with brachymetatarsia. The goal of this study was to determine the length of the proximal phalanx in the setting of brachymetatarsia, and how much the shortening is attributed to the clinically smaller toe. We performed a retrospective study to evaluate the length of the proximal phalanx in the shortened ray. After the metatarsal was brought out to the desired length of correction, the proximal phalanx was measured on radiographs. Ninety-seven feet with congenital brachymetatarsia were reviewed in a cohort of 66 patients who underwent surgical correction between January 2005 and February 2020 at a single institution. The group was comprised of 61 females and 5 males, with a mean age of 27.5 years. The average length of the proximal phalanx associated with the affected metatarsal was noted to be 18.9 ± 3.83 mm for males and 15.6 ± 4.02 mm for females. Our results indicate the shortened proximal phalanx is 5 mm shorter when compared to normal population and is a contributing factor to the shortened clinical appearance of the digit in brachymetatarsia. Treating surgeons should be aware of this to better educate patients on the influence of the digit on the overall shortening seen in cases of brachymetatarsia.
短跖骨症是一种跖骨未能生长至全长的病症。这是由骨骺过早闭合引起的。与缩短的跖骨相关的近节趾骨有助于实现足部自然的抛物线形态。近节趾骨发育不全是短跖骨症患者的常见表现。本研究的目的是确定短跖骨症情况下近节趾骨的长度，以及缩短的程度在多大程度上归因于临床上较小的脚趾。我们进行了一项回顾性研究，以评估缩短的跖骨射线中近节趾骨的长度。在将跖骨延长至所需的矫正长度后，在X线片上测量近节趾骨。对2005年1月至2020年2月在单一机构接受手术矫正的66例患者队列中的97只患有先天性短跖骨症的脚进行了评估。该组包括61名女性和5名男性，平均年龄为27.5岁。发现与受影响跖骨相关的近节趾骨平均长度，男性为18.9±3.83毫米，女性为15.6±4.02毫米。我们的结果表明，与正常人群相比，缩短的近节趾骨短5毫米，并且是短跖骨症中脚趾临床外观缩短的一个促成因素。治疗外科医生应意识到这一点，以便更好地向患者说明该趾对短跖骨症病例中整体缩短的影响。
