A common treatment of tibial defects especially after infections is bone transport via external fixation. We compare complications and outcomes of 25 patients treated with a typical Ilizarov frame or a hybrid system for bone reconstruction of the tibia. Average follow up was 5.1 years. Particular interest was paid to the following criteria: injury type, comorbidities, development of osteitis and outcome of the different therapies. The reason for segmental resection was a second or third grade open tibia fractures in 24 cases and in one case an infection after plate osteosynthesis. Average age of the patients was 41 years (range 19 to 65 years) and average defect size 6.6 cm (range 3.0 to 13.4 cm). After a mean time of 113 days 23 tibial defects were reconstructed, so we calculated an average healing index of 44.2 days/cm. Two patients with major comorbidities needed a below knee amputation. The presence of osteitis led to a more complicated course of therapy. In the follow up patients with an Ilizarov frame had better results than patients with hybrid systems. Bone transport using external fixation is suitable for larger defect reconstruction. With significant comorbidities, however, a primary amputation or other methods must be considered.

Background: The treatment of pilon tibia fractures is challenging. Anatomical reduction of the joint surface is essential. Excessive soft-tissue dissection may interfere with the blood supply and can result in nonunion. We sought to compare the outcomes of distal tibia fractures treated with medial locking plates versus circular external fixators. Methods: We retrospectively evaluated 41 consecutive patients with closed pilon tibia fractures treated with either minimally invasive locking plate osteosynthesis (n = 21) or external fixation (EF) (n = 20). According to the Ruedi and Allgower classification, 23 fractures were type B and 18 were type C. Soft-tissue injury was evaluated according to the Oestern and Tscherne classification. Time to fracture union, complications, and functional outcomes were assessed annually for 3 years with the American Orthopaedic Foot and Ankle Society (AOFAS) ankle score. Results: Mean ± SD values in the plate group were as follows: age, 42.4 ± 14 years; union time, 19.4 ± 2.89 weeks (range, 12–26 weeks); and AOFAS ankle scores, 86.4 ± 2.06, 79.5 ± 1.03, and 77.9 ± 0.80 at 1, 2, and 3 years, respectively. Four patients in the plate group needed secondary bone grafting during follow-up. In the EF group (mean ± SD age, 40.7 ± 12.3 years), all of the patients achieved union without secondary bone grafting at a mean ± SD of 22.1 ± 1.7 weeks (range, 18–24 weeks). In the EF group, mean ± SD AOFAS ankle scores were 86.6 ± 1.69, 82.1 ± 0.77, and 79.7 ± 1.06 at 1, 2, and 3 years, respectively. There were no major complications. However, there were soft-tissue infections over the medial malleolus in five patients in the plate group and grade 1-2 pin-tract infections in 13 patients and grade 3 pin-tract infections in one patient in the EF group. Post-traumatic arthritis was detected in eight plate group patients and seven EF group patients. Conclusions: Minimally invasive plating and circular EF methods have favorable union rates with fewer complications.

Acute Shortening

This prospective study compared bifocal acute shortening and relengthening (ASR) with bone transport (BT) in a consecutive series of complex tibial infected non-unions and osteomyelitis, for the reconstruction of segmental defects created at the surgical resection of the infection. Patients with an infected tibial segmental defect (>2 cm) were eligible for inclusion. Patients were allocated to ASR or BT, using a standardized protocol, depending on defect size, the condition of soft tissues and the state of the fibula (intact or divided). We recorded the Weber–Cech classification, previous operations, external fixation time, external fixation index (EFI), follow-up duration, time to union, ASAMI bone and functional scores and complications. A total of 47 patients (ASR: 20 patients, BT: 27 patients) with a median follow-up of 37.9 months (range 16–128) were included. In the ASR group, the mean bone defect size measured 4.0 cm, and the mean frame time was 8.8 months. In the BT group, the mean bone defect size measured 5.9cm, and the mean frame time was 10.3 months. There was no statistically significant difference in the EFI between ASR and BT (2.0 and 1.8 months/cm, respectively) (p = 0.223). A total of 3/20 patients of the ASR and 15/27 of the BT group needed further unplanned surgery during Ilizarov treatment (p = 0.006). Docking site surgery was significantly more frequent in BT; 66.7%, versus ASL; 5.0% (p < 0.0001). The infection eradication rate was 100% in both groups at final follow-up. Final ASAMI functional rating scores and bone scores were similar in both groups. Segmental resection with the Ilizarov method is effective and safe for reconstruction of infected tibial defects, allowing the eradication of infection and high union rates. However, BT demonstrated a higher rate of unplanned surgeries, especially docking site revisions. Acute shortening and relengthening does not reduce the fixator index. Both techniques deliver good functional outcome after completion of treatment.

Abstract Background: This study aimed to evaluate the clinical and functional outcomes of patients with critical femoral and tibial bone defects treated by trifocal bone transport using the Ilizarov method.Methods: In a retrospective comparative study, 39 patients treated for lower limb bone non-union with bone loss measuring between 6 and 14 cm were included. Depending on the location of bone transport, the patients were divided into the femur group (n =18) and tibia groups (n =21). The demographics data, intraoperative records, and postoperative outcomes were documented and compared between the two groups. At the last follow-up, the bone and functional outcomes were evaluated according to the criterion given by the Association for the Study and Application of the Method of the Ilizarov (ASAMI) and postoperative complications evaluated by Paley classification.Results: The average follow-up time was 26.1 months (range 17–34 months) since the unilateral external fixators were removed. The mean size of the bone defect was 8.3 cm in the femur group, and 7.5 cm in the tibia group. All bone defects were reconstructed successfully. The mean time in external fixation in the femur group was 334.4 days, and in the tibia group was 344.6 days. The external fixation index (EFI) measured 55.9 days/cm in the femur group and 65 days/cm in the tibia group. A statistically significant difference of bone grade was found between the two groups (excellent/good/fair/poor, 3/11/3/1 vs 2/13/4/2, P<0.05), as well as the function grade in two groups (excellent/good/fair/poor/failure, 3/14/1/0 vs 4/13/3/1, P<0.05). According to the ASAMI classification, the clinical and functional results in the femur group were better than in the tibia group. The complication rate of the two groups was 94.4% vs 76.2% (femur vs tibia). One femur and five tibias were performed additional surgery because of delayed union and axial deviation. Conclusions: The trifocal bone transport using the unilateral external fixator is a reliable treatment in the management of post-traumatic and post-infection lower limb bone defects (>6cm). In the comparison of the tibia, the trifocal bone transport treatment period of the femur was shorter, the functional recovery was better and the risk of minor complications was higher.

Objective To report the results of patients with short oblique diaphyseal tibia fractures treated with minimally invasive plate osteosynthesis (MIPO). The secondary aim was to understand the effect of fracture location (midshaft or distal 1/3) on outcomes. Methods Twenty-eight patients with short oblique (>30°) tibial shaft fractures (AO/OTA 42A2) treated with plate and MIPO technique between 2015 and 2019 were retrospectively assessed. Age, gender, follow-up time, fracture type (open or closed), operation time, postoperative infection rate, union time, ankle joint range of motion, and complications were analyzed. Patients’ radiographs at a minimum 1-year follow-up were evaluated for malunion, nonunion, and implant-related complications. Results Mean age and follow-up time were 47.0 ± 15.7 years and 18.3 ± 12.1 months, respectively. Mean bone union time was 3.66 ± 1.04 months in middle 1/3 diaphysis and 4.23 ± 1.48 months in distal 1/3 tibia fractures. Seven (25%) patients developed superficial infections. Mean union time, malunion rate, coronal and sagittal angulation, operation length, and infection rate were similar between the groups. Conclusion MIPO is an effective method for treatment of short oblique diaphyseal tibia fractures, and results in few complications. Both distal and midshaft fractures have similar union and malunion rates.

Objective To evaluate the effectiveness of bone transport involving circular external fixation and locking plate application for the treatment of segmental tibial defects. Methods A retrospective review of 12 patients with segmental tibial defects who underwent bone transport with circular external fixation and locking plate application. We evaluated external fixation time, external fixation index, time to achieve union, and complications. Clinical results were assessed using the Association for the Study and Application of the Methods of Ilizarov (ASAMI) score. Generic health-related outcome was assessed using the 36-Item Short-Form Health Survey questionnaire (SF-36). Results The mean follow-up was 25.8 months, and the mean defect size was 6.7 cm. All of the patients achieved union at the distraction callus and docking site. The average external fixation time was 299.5 days. The mean external fixation index was 16.5 days/cm, and the mean healing index was 44.9 days/cm. The functional outcomes were excellent in eight cases and good in four. The average SF-36 score was 92. Conclusion Bone transport with external fixation and locking plate application may be a promising method for the treatment of segmental tibial defects.

Background: Expert guidelines recommend annual monitoring of 25-hydroxyvitamin D (25-OHD) and maintaining 25-OHD ≥30 ng/ml in patients with dystrophinopathies. Objective: We hypothesized that 25-OHD remains stable and requires less frequent monitoring in patients taking stable maintenance doses of vitamin D. Methods: We performed a retrospective cohort study, using the electronic health record to identify 26 patients with dystrophinopathies with a baseline 25-OHD ≥30 ng/mL and at least one additional 25-OHD measurement. These patients had received a stable dose of vitamin D for ≥3 months prior to their baseline 25-OHD measurement and throughout follow-up. The main outcome measured was the mean duration time the subjects spent with a 25-OHD ≥30 ng/mL. Results: Only 19% of patients dropped their 25-OHD to <  30 ng/ml, with a mean time to drop of 33 months and a median nadir 25-OHD of 28 ng/mL. Conclusions: These results suggest that measurement of 25-OHD every 2–2.5 years may be sufficient in patients with a baseline 25-OHD ≥30 ng/mL and who are on a stable maintenance dose of vitamin D. Other patients may require more frequent assessments.

Treatment of congenital pseudarthrosis of the tibia remains a major challenge in pediatric orthopedics. Ideal timing and preference of surgical procedures are discussed controversially. A variety of reconstructive treatment strategies have been described in literature, but so far none has proven its superiority. The aim of treatment is to obtain long-term bone union, to prevent refracture, and to correct angular deformities and leg length discrepancies. This study retrospectively evaluates the outcome of different reconstructive strategies. Sixty-nine patients were identified who presented to our outpatient department between 1997 and 2019. Twenty-six of these patients underwent reconstructive surgical treatment and were included in this study. The study cohort was divided into three groups. Excision of the pseudarthrosis was performed in all patients in Group A and B, and in two patients of Group C. Group A (six/26 patients) received subsequent bone transport through external fixation maintaining original length. In Group B (15/26 patients), patients underwent either previous, simultaneous, or subsequent extrafocal lengthening through external fixation to reconstitute length. In Group C (five/26 patients), internal fixation with intramedullary nails was applied. Radiological and clinical evaluation was performed to assess bone union and complication rates. Results varied considerably between the study groups. Overall, the primary bone fusion rate was 69.2%. There were four refractures, all occurring in Group B. The long-term bone union rate without refracture was 53.8%. The overall complication rate was 53.8% and 23.1% showed persistent pseudarthrosis. Two secondary amputations were performed due to failed bone fusion. In conclusion, excision of the pseudarthrosis and extrafocal lengthening achieves a satisfying bone union rate and limb reconstruction, while bone transport does not offer significant advantages but shows higher complication rates. Intramedullary stabilization should be applied to maintain bone union, but shows lower bone union rates when used as a stand-alone treatment regimen. Regardless of the primary bone fusion rates, the probability of long-term bone union remains unpredictable.
