Improved Ilizarov method for management of deformity and ulceration on foot and ankle of spina bifida

Objective To evaluate the clinical curative effect of Ilizarov external fixation and ankle arthrodesis in the treatment of elderly traumatic ankle arthritis. Methods From June 2013 to August 2019, 72 patients with elderly traumatic ankle arthritis were treated with arthrodesis through Ilizarov external fixation technique in our institution. Conventional double‐feet standing X‐ray films were taken before and after operation. The tibiotalar angle on X‐ray image was measured to evaluate the degree of talipes varus and valgus. The Foot and Ankle pain score of American Orthopaedics Foot and Ankle Society (AOFAS) and Visual Analog Scale (VAS) were compared by using paired t‐test to evaluate the functional recovery. Results All of the patients acquired effective postoperative 18–49 months follow‐up, with an average of 31.5 months. All patients were included in the analysis, among which 38 cases were males and 34 cases were females, with an average of 65.4 years (ranging from 60 to 74). All ankles achieved bony fusion; the clinical healing time was 12.7 weeks on average (11–18 weeks). The AOFAS score was 45.36 ± 6.43 preoperatively and 80.25 ± 9.16 at 12 months post‐operation, with a statistically significant difference (p < 0.0001). The VAS score was 8.56 ± 1.85 on average preoperatively and 2.72 ± 0.83 at 12 months post‐operation, with a statistically significant difference (p < 0.0001). The tibiotalar angle was 101.93° ± 4.12° preoperatively and 94.45° ± 2.37° at 12 months post‐operation, with a statistically significant difference (p < 0.0001). The results of the functional evaluation indicated that 44 patients (61.1%) had excellent results, 18 (25%) had good results, and 10 (13.9%) had fair results. Conclusion Our study demonstrated that it is possible to obtain satisfactory outcome with Ilizarov external fixation and ankle arthrodesis in the treatment of elderly traumatic ankle arthritis.

ObjectiveThe principles of limb reconstruction are crucial for treatment success, but there is no unified standard for complex limb deformities. The aim of this study was to analyze the characteristics of the cases of post‐traumatic lower limb deformity and explore the new principle of limb reconstruction.MethodA retrospective analysis was conducted of 148 patients with post‐traumatic lower limb deformity who underwent surgery from May 1978 to December 2023; 85 were males (57.4%) and 63 were females (42.6%); 65 cases of left side (43.9%), 79 cases of right side(53.4%), and 4 cases were on both sides (2.7%), the average age was 24.64 years (5–69). There were 4 cases suffering hip deformities, 40 cases of femoral deformities, 18 cases from knee, 40 cases from tibiofibular, 93 cases of foot and ankle deformities, and some patients also had two or more types. All patients underwent surgical intervention in an average of 40.5 months (12–96) after injury. According to the evaluation of limb deformities, deformity correction and functional reconstruction with external fixation were implemented, following the principle of “one walking, two lines, and three balances.” The clinical evaluation adopts the criteria of Qinsihe lower limb deformity correction and functional reconstruction.Result148 patients with post‐traumatic lower limb deformities were followed up for 40.9 (12–356) months. The main surgical procedures implemented were tendon lengthening and soft tissue release (84 cases), osteotomy (93 cases), joint fusion (30 cases), and tendon transposition (16 cases); there were multiple surgical procedures in some patients. Among them, 124 cases used external fixators for stress control and 27 cases used internal fixation, while 3 cases used plaster or brace. There were 5 wire reactions postoperatively, which improved after dressing change and oral antibiotics. There were 2 pin infections, which improved by pin removing. No surgical related deep infections occurred, and no surgical related neurovascular damage occurred. At the last follow‐up, all limb deformities were corrected, limb function improved, and the results of treatment was very satisfactory. According to Qinsihe evaluation criteria for lower limb deformities, 74 cases were excellent, 56 cases good, and 18 cases fair, with an excellent and good rate of 87.84%.ConclusionStress control with external fixation is effective, safe, and controllable in correcting and reconstructing post‐traumatic lower limb deformities. The principle of “one walking, two lines, and three balances” plays an important role in the entire process of stress control limb reconstruction.

Preliminary Outcomes of Calcaneal Body Lengthening for the Calcaneus Shortening

For lengthening irregular bones, such as calcaneus, there are few reports in the literature. This study aimed to introduce the treatment strategy and preliminary outcomes for calcaneus shortening using calcaneal body lengthening. From January 2017 to January 2022, calcaneal lengthening was conducted for three patients (two males and one female) who suffered from traumatic calcaneal shortening. The Achilles tendon was lengthened in one patient. After osteotomy of the calcaneus, an Ilizarov frame was used to gradually (1 mm/day) distract the calcaneal fragment. The lengthening procedure was stopped when the calcaneal height and length were restored based on radiography. The fixator was removed after bone union. The average follow‐up length was 18 months (range, 14–24 months). X‐ray was used for radiological assessments. Patients reported satisfaction using the 100‐mm visual analog scale (VAS). Clinical outcome was evaluated following the American Orthopedic Foot and Ankle score. All data were assessed by two physicians blind to clinical assessments. The wound healed primarily in three cases. The bone got solid union without refracture and malunion. The distraction time was 30 days (range, 25–45 days). The fixation time was 113.3 days (average, 80–150 days). Calcaneal lengthening was 26 mm (range, 15–43 mm). The height and length of the calcaneus were restored nearly to the same as the opposite foot. The mean preoperative calcaneal pitch angle increased from 2.6 degrees to an average of 19.0 degrees after the surgery. The AOFAS score increased from 60.0 to 86.0. One patient experienced pin infection. The infection healed after changing the dressing. Calcaneal lengthening using an Ilizarov external fixator is a preferable technique to restore the length and height of the calcaneus and can achieve satisfactory foot function.
