为了对中跗骨畸形进行分类，使用临床检查和负重X线片对109例患者（平均年龄59 ± 11岁）的131只足进行了评估。根据最大畸形的解剖位置将患者分为四种类型。I型（N = 43）表现为跖楔关节内侧畸形，第4、5跖骰关节外侧畸形，跖内侧和/或内侧突出。II型（N = 60）在舟楔关节内侧和第四和第五跖骰关节外侧畸形;跖外侧突出是特征性的，尽管三分之一有孤立的或额外的内侧突出。III型（N = 17）在舟周区域有严重的畸形，具有突出的跖中央或跖外侧。IV型（N = 11）在横向跗关节处有畸形，具有可变的弯曲度。根据畸形的严重程度，每种类型进一步细分为A、B和C期。B期，中跗骨与跖跟平面共面。在A阶段，中跗骨在这个平面之上。在C阶段，中跗骨在这个平面之下。我们的结论是，中跗骨畸形可以分为四种类型和三个阶段之一。进一步的研究是必要的，以关联这一系统与预后和治疗这一病理过程。
To develop a classification of midtarsus deformities, clinical examination and weightbearing radiographs were used to evaluate 131 feet in 109 patients (average age, 59 +/- 11 years) with those deformities. Patients were classified into four types based on anatomic location of the maximum deformity. Type I (N = 43) showed deformity at the metatarsocuneiform joints medially and the fourth and fifth metatarsocuboid joints laterally, with plantarmedial and/or medial prominence. Type II (N = 60) had deformity at the naviculocuneiform joint medially and the fourth and fifth metatarsocuboid joints laterally; plantarlateral prominence was characteristic, although one-third had isolated or additional medial prominences. Type ill (N = 17) had major deformity in the perinavicular region, with a prominence plantarcentrally or plantarlaterally. Type IV (N = 11) had deformity at the transverse tarsal joints with variable prominences. Each type was further subdivided into stages A, B, and C based on the severity of the deformity. In stage B, the midtarsus was coplanar with the metatarsocalcaneal plane. In stage A, the midtarsus was above this plane. In stage C, the midtarsus was below this plane. We concluded that midtarsus deformities can be classified as one of four types and one of three stages. Additional study is warranted to correlate this system with prognosis and treatment for this pathologic process.
