Abstract
Purpose
The research is aimed to introduce various corrective osteotomies utilized in treating calcaneal malunions in published papers, to further analyze the results, and to summarize recommended indications.
Methods
The relevant research screening was conducted on the following search engines: the Cochrane Library, Web of Science, PubMed, Embase, Medline, and Academic Search Premier. Key words input included “calcaneal/calcaneus”, “malunion,” and “malunited fracture(s)” with Boolean operators “AND” and “OR.” The inclusion criteria were researches containing surgical procedures treating calcaneal malunion with corrective osteotomy and published in the English language. For included research article, such information was extracted and analyzed: the type of calcaneal malunion, the time from initial injury to corrective surgery, the method of osteotomy, outcomes of each osteotomy (score systems, Bohler angle, talocalcaneal height and width of calcaneus, etc.), the function of the affected limb, post-operative complications, and patients’ satisfaction. For included review, descriptive, commentary, or indicative sentences about corrective osteotomy were highlighted, analyzed, and summarized.
Results
Ten research articles (170 patients with 184 feet) and nine reviews were included in this review, presenting seven types of corrective osteotomies (lateral wall exostectomy, Dwyer osteotomy, lateral wedge opening osteotomy, Romash osteotomy, tongue osteotomy, sagittal resection osteotomy, and modified Dwyer osteotomy).
Conclusion
A different corrective osteotomy with/without arthrodesis is recommended to be utilized based on the classification of the malunion and the condition of the cartilage in treating malunited calcaneal fractures. With adequate postoperative care and rehabilitation, the results of treatment could be associated with patients’ satisfaction and good function.
