AI Article Synopsis

  • The study aimed to evaluate the effectiveness of reconstructing the calcaneal thalamus and performing subtalar arthrodesis for treating serious old intra-articular calcaneal fractures in 26 patients.
  • Results indicated significant improvements in foot function, as measured by the AOFAS Ankle-Hindfoot Scale, with all patients showing successful healing and no major complications reported.
  • The findings suggest that this surgical approach significantly enhances both structural and functional outcomes for patients with these types of fractures.

Article Abstract

Objective: To observe the outcome of treatment for serious old intra-articular calcaneal fracture by reconstruction of calcaneal thalamus and subtalar arthrodesis and to summarize the operative indications and its attention points.

Methods: From March 2006 to July 2011,26 patients with Sanders type III old intra-articular calcaneal fracture were treated including 15 males and 11 females with an average age of 34 years old ranging from 27 to 45 years old. The clinical courses ranged from 7 to 24 months with an average of 18 months. Before the operation,X-ray and CT showed that Gissane angle increased while Böhler angle decreased,and calcaneus broadened,bulging on both sides. After the operations,all patients tested by imaging examination, and the width of calcaneus, the height of calcaneal thalamus, the Böhler angle and Gissane angle were measured to compare with the preoperative data. Besides, for identification of improvement of the operation,the functions of patient's feet after the operation were graded according to AOFAS Ankle-Hindfoot Scale to compare with preoperative data.

Results: Among them, 24 patients were followed-up from 5 to 26 months with an average of 19 months. X-rays confirmed that all cases healed successfully. There were no serious infection, and only one skin necrosis case. Sural neurocutaneous island flap was used to repair the skin with success. According to AOFAS Ankle-Hindfoot Scale, the total score increased from preoperative (41.00 +/- 8.22) to postoperative (79.04 +/- 7.46). There were 3 cases of excellent result, 15 cases of good result,and 6 cases of fair result. Postoperative width of calcaneus, the height of thalamus, Böhler angle and Gissane angle were better than that of preoperative data, and had statistical significance between two groups.

Conclusion: Subtalar arthrodesis with the reconstruction of calcaneal thalamus is an effective way to treat old intra-articular calcaneal fractures. It can correct the calcaneal deformity, restore the shape of foot and improve the function of hind foot.

Purpose: No computer-assisted pre-operative design for calcaneal fracture malunions has been presented. The aim of the study is to evaluate the intra-operative realization of computer-assisted pre-operative planning (CAPP) and the clinical outcomes based on computer-assisted virtual surgical technology for calcaneal malunions.

Methods: Between 2010 and 2016, 20 patients with 21 calcaneal fracture malunions were retrospectively reviewed with the average follow-up time of 22.

Arthroscopy has become indispensable for performing tibiotalar and subtalar arthrodesis. Now in 2015, it is the gold-standard surgical technique, and open surgery is reserved only for cases in which arthroscopy is contraindicated: material ablation after consolidation failure, osteophytes precluding a work chamber, excentric talus, severe malunion, bone defect requiring grafting, associated midfoot deformity, etc. The first reports of arthroscopic tibiotalar and subtalar arthrodesis date from the early 1990s.
