Calcaneal fracture patterns vary widely, and many factors determine the type and timing of the treatment rendered. Severe calcaneus fractures involving joint damage, loss of heel height, and varus deformity of the tuberosity are ideally treated with open reduction and internal fixation to repair the joint surface and re-establish anatomic structure. This is not always possible owing to delayed presentation, soft tissue compromise, unrelated injuries, unstable medical condition, or lack of expertise by the treating physician. We present the case of a patient who had residual forefoot and rearfoot deformity despite undergoing delayed subtalar joint arthrodesis at an outside hospital 10 years before for a calcaneal fracture that was initially treated nonoperatively. At 4 years of follow-up after modified Dwyer calcaneal osteotomy with rotation and reinsertion of the autograft bone wedge and Cotton midfoot osteotomy, the postoperative gait was relatively normal, other than the expected lack of hindfoot mobility. The lateral column pain was resolved. The patient remained highly satisfied with the outcome at long-term follow-up of 48 months, with improved heel alignment, lack of a wide stance gait, a functional medial column, and a relatively normal gait. This case demonstrates the value of periarticular calcaneal osteotomies without the need to revise the subtalar joint arthrodesis for this challenging clinical situation.
跟骨骨折的类型差异很大,许多因素决定了所采取治疗的类型和时机。涉及关节损伤、足跟高度丢失以及结节内翻畸形的严重跟骨骨折,理想的治疗方法是切开复位内固定,以修复关节面并重建解剖结构。但由于就诊延迟、软组织受损、合并其他损伤、病情不稳定或治疗医生缺乏专业知识,这种方法并非总能实现。我们报告一例患者,该患者10年前因跟骨骨折在外院接受了延迟距下关节融合术,最初采用非手术治疗,尽管如此,患者仍残留前足和后足畸形。在采用改良Dwyer跟骨截骨术旋转并重新植入自体骨楔以及Cotton中足截骨术后4年的随访中,除了预期的后足活动度受限外,术后步态相对正常。外侧柱疼痛得到缓解。在48个月的长期随访中,患者对结果仍高度满意,足跟对线改善,无宽基底步态,内侧柱功能良好,步态相对正常。该病例证明了在这种具有挑战性的临床情况下,关节周围跟骨截骨术的价值,而无需对距下关节融合术进行翻修。
