Abstract：

Objective To compare unilateral and bilateral external fixators in the surgical treatment of fractures of distal tibia. Methods From August 2005 to February 2010, 38 patients with distal tibial fracture were treated surgically in our department. Of them, 23 (group A) were fixed with unilateral external fixator (16 males and 7 females with a mean age of 46. 5 years), and 15 (group B) fixed with bilateral external fixator (11 males and 4 females with a mean age of 49. 1 years) . All the patients were followed up periodically after operation. Time of fracture healing, complications, the American Orthopaedic Foot and Ankle Society (AOFAS) scores for the ankle were documented and analyzed statistically to compare the clinical outcomes of the 2 groups. Results The patients were followed up for 6 to 48 months (mean, 21 months).The mean time for clinical fracture union was 6. 8 ± 2. 0 months (3. S to 12. 0 months) for group A, and 5. 6 ± 1. 5 months (3 to 10 months) for group B. The complication rates during external fixation were 34. 8% (8/23) for group A and 40.0% (6/15) for group B. The AOFAS scores for functional recovery were 76. 7 ± 13. 5 for group A and 74. 4 ± 13. 6 for group B. Independent samples t test showed a significant difference ( P < 0. 05) between the 2 groups in time of clinical fracture union, but no significant difference (t = 2. 074, P = 0. 046) in complication rates and AOFAS scores. Conclusion Both unilateral and bilateral external fixators are effective for fixation of distal tibial fractures, but bilateral external fixators may be better in time of fracture healing.

Comparison of internal and external fixation after debridement in the Masquelet technique for Cierny-Mader type IV tibial post-traumatic osteomyelitis

ObjectiveTo compare the effect of internal fixation vs. external fixation after debridement in stage I of the Masquelet technique for Cierny-Mader (C-M) type Ⅳ chronic post-traumatic tibial osteomyelitis.MethodsThis retrospective observational study included patients with tibial osteomyelitis who underwent staged treatment with the Masquelet technique between January 2016 and June 2020 at the 920 Hospital of Joint Logistic Support Force of the PLA. The patients were grouped according to the fixation they received after stage I. Infection recurrence, time to radiological bone healing and full weight-bearing, self-rating anxiety scale (SAS) score, Hospital for Special Surgery (HSS) Knee Score, and American Orthopedic Foot and Ankle Society (AOFAS) Ankle-Hindfoot Score were compared.ResultsSixty-three patients were included (50 males and 13 females). There were 40 and 23 patients with internal and external fixation, respectively. There were no significant differences between the two groups regarding the preoperative and intraoperative data (all P>0.05). After stage I operation, the infection control rates were 85.0% and 82.6% in the internal and external fixation groups (P=0.803), and these rates were 92.5% and 95.7% after stage II (P=0.621). There were no differences in the SAS scores (P=0.278), time to radiological union (P=0.795), time to full weight-bearing (P=0.725), AOFAS scores (P=0.302), HSS scores (P=0.085), and complication rates (P=0.593). There were 27 times complications in 19 patients, with an incidence of 42.9%, without significant differences between groups.ConclusionThere were no differences between the two fixation methods after debridement in stage I of the Masquelet technique for C-M type Ⅳ chronic post-traumatic tibia osteomyelitis.     

Ten year experience with use of Ilizarov bone transport for tibial defects

Tibial defects greater than 4 cm and secondary to high-energy trauma or debridement for infected nonunion pose a significant challenge to the treating orthopaedic surgeon. Twelve patients who had been treated with Ilizarov bone transport for tibial defects over the past ten years were retrospectively reviewed. All patients were male with an average age of thirty-two. Ten of the twelve limbs were categorized as Grade IIIB fractures initially. The average tibial defect at initiation of bone transport was 9.45 cm (range 4 to 20 cm). The mean external fixator time (EFT) was 16.7 months with a mean external fixator index (EFI) of 2.0 months per centimeter. There were a total of 36 complications. Twenty were minor, fourteen were major without sequelae and two were major with sequelae. Overall bone results were good or excellent in nine patients. Overall functional results were good or excellent in eight patients. Ten patients achieved union after Ilizarov bone transport. Use of Ilizarov bone transport can be an effective tool for treating large tibial defects. However, the treatment time is lengthy with a considerable risk of complications.

Tetrafocal (three osteotomies) and pentafocal (four osteotomies) bone transport using Ilizarov technique in the treatment of distal tibial defect—preliminary outcomes of 12 cases and a description of the surgical technique

ObjectiveTo evaluate the preliminary outcomes of tetrafocal (three osteotomies) and pentafocal (four osteotomies) bone transport using Ilizarov technique for the treatment of distal tibial defect and describe the surgical technique.MethodsA total of 12 eligible patients with distal tibial defect > 6 cm caused by direct trauma or posttraumatic osteomyelitis who were admitted to our institution from January 2017 to January 2019 were treated by tetrafocal or pentafocal bone transport using Ilizarov technique. Detailed demographic data, including age, sex, etiology, defect size, number of osteotomies (three or four), external fixation time (EFT) and external fixation index (EFI), were collected, and the bone and functional outcomes were evaluated by the Association for the Study and Application of the Method of Ilizarov (ASAMI) scoring system. Complications during the surgery and the follow-up period were recorded and evaluated by the Paley classification at a minimum follow-up of two years after removal of the fixator.ResultsThere were 9 men and 3 women with an average age of 37.4±7.8 years. The etiology included posttraumatic osteomyelitis in 8 cases and posttraumatic bone loss in 4 cases. The mean bone defect after radical debridement was 7.1±0.6 cm. Tetrafocal bone transport was applied in 9 cases, and pentafocal bone transport was applied in 3 cases. The average EFT and EFI were 5.2±0.8 months and 0.7±0.2 months/cm, respectively. The average time of follow-up after removal of the external fixator was 28.5±3.3 months without recurrence of osteomyelitis. The bone results were good in 7 cases, fair in 4 cases, and poor in 1 case, and the functional results were good in 5 cases, fair in 6 cases, and poor in 1 case. The most common complication was pin tract infection, which occurred in all cases, but there were no major complications, such as nerve or vascular injury.ConclusionTetrafocal and pentafocal bone transport using Ilizarov technique could be an alternative treatment option in selected cases with distal tibial defect > 6 cm.
