The relative length and height of the lateral and medial walls of the calcaneum probably govern the production and persistence of structural hindfoot deformity, forefoot supination and adduction, and pronation and abduction. Anatomical restoration of the proportions of the calcaneal walls forms the basis of the T-osteotomy of the calcaneum. We have undertaken this operation on 72 feet in 60 patients for cavovarus deformity with forefoot adduction. The calcaneum is approached from the lateral side and the T-shaped osteotomy is performed through the body, the vertical limb being 1 to 1.5 cm behind and parallel to the calcaneo-cuboid joint. The horizontal limb starts from the centre of the vertical cut and ends above the attachment of the tendo achillis. The postero-inferior segment is pushed out correcting the heel varus and at the same time broadening the heel. The forefoot is manipulated downwards and outwards to correct the residual cavus and the adduction and supination of the forefoot. The over-all results, with an average follow-up of 3.7 years, have been satisfactory.
跟骨外侧壁和内侧壁的相对长度及高度可能决定了后足结构性畸形、前足内旋和内收以及旋前和外展的产生与持续存在。跟骨壁比例的解剖学恢复构成了跟骨T形截骨术的基础。我们对60例患者的72只足进行了该手术，用于治疗伴有前足内收的高弓内翻畸形。从外侧进入跟骨，通过跟骨体进行T形截骨，垂直肢位于跟骰关节后方1至1.5厘米处并与之平行。水平肢从垂直切口的中心开始，止于跟腱附着点上方。将后下部分推出，纠正足跟内翻，同时加宽足跟。向下并向外操作前足，以纠正残留的高弓以及前足的内收和内旋。平均随访3.7年，总体结果令人满意。
