Extreme bone lengthening by bone transport with a unifocal tibial corticotomy: a case report.

ABSTRACT:

Background

Bone transport is used for the treatment of extensive limb bone defects. The application of ring or unilateral external fixators combined with single or double corticotomy are well documented; however, there are few cases adopting a single corticotomy to repair bone defects >?24?cm.

Case presentation

The present case study describes an 18-year-old male, who was involved in a traffic accident and was diagnosed with open fracture of the right tibia. The patient received emergency surgery in a local hospital and was transferred to The Second People's Hospital of Yunnan for further treatment 3 months later. The patient was diagnosed with fracture nonunion and infection following admission. Complete debridement was performed three times to control the infection. The infection was resolved after 26?days and the 24.5?cm massive tibia defect remained the biggest challenge. The bone transport technique involving a unilateral external fixator and single corticotomy was employed to treat the bone defect. Docking site union was achieved and bone consolidation was complete 40?months after corticotomy. The external fixator was subsequently removed. The bone healing index was 1.6?months/cm. The Association for the Study and Application of the Method of Ilizarov criteria (ASAMI) revealed a good functional and bone repair result. Similarly, Knee Society Score (KSS) yielded good result and the The Lower Extremity Functional Scale (LEFS) was 65. A total of 45?months after injury, the patient was able to walk painlessly without ambulatory assistive devices and resumed daily activities successfully. Eighteen?months after the bone and soft tissue wound have healed, the SF-36 score was 86, and the LEFS was 70.

Conclusion

To the best of the authors' knowledge, the present study described the longest bone defect repair performed using bone transport with single level corticotomy.

Project description:RationaleTibial hemimelia is known as a rare congenital lower limb deficiency. It has been classified into different types based on Jones classification, and the traditional treatment of tibial hemimelia is amputation. Here we present a variant and unclassified case of tibial hemimelia, which was caused by osteomyelitis. And the lower limb with tibial hemimelia was salvaged by asymmetric limb lengthening.Patient concerns19-year-old girl had the shortened and curved left lower extremity with walking abnormalities.DiagnosisThe patient's deformity was caused by osteomyelitis of tibia occurred when she was 18 month old. The tibial shaft was absent, while the proximal and distal tibia was present but was hypoplastic with radiographic analysis. The fibula was hypertrophied and curved like the capital letter C. The leg length discrepancy (LLD), mostly coming from the left lower leg, was 22 cm.InterventionsWe were able to salvage the limb successfully by 5 operations, including releasing soft tissue, fusing the proximal tibiofibular joint, fibular osteotomy, femur lengthening, and fibular lengthening.OutcomesThe whole treatment time for the patient was 3 years and 2 months, and she was followed up for 5 years afterward. The length of femur lengthening and fibula lengthening during the reconstruction were 7.8 cm and 11 cm, respectively. Most of the deformities were corrected, except that the left lower limb was still 2 cm shorter than the contralateral limb, and the 34 mm of mechanical axis deviation (MAD) of left lower limb remained. The reason why the patient's lower limbs were asymmetric was that the femur and fibular lengthening were performed within the affected limb only. Overall, the patient was very satisfied with her asymmetric limbs and its function after surgeries.LessonsThe LLD in this case mainly came from tibial hemimelia. However, the fibula was unable to be lengthened to 22 cm during the lower leg distraction process because of blood flow disturbance. We could only lengthen the femur to salvage the limb in this situation. Even though the patient still had a few residual deformities and a pair of asymmetric lower limbs, she was satisfied with the function and appearance of the reconstructed limb. Therefore, the lower limb with tibial hemimelia can be salvaged by asymmetric limb lengthening in special cases.

Project description:Introduction and importance: Unicondylar tibial plateau fractures with tibial shaft fractures are extremely rare among the elderly group of people. The traditional treatment method is to apply double plates to fix unicondylar tibial plateau fractures combined with tibial shaft fractures respectively, but this fixation method can disrupt the blood supply around the soft tissues and increase the rate of postoperative infection and fracture non-union. In this paper, we would analyse an old unicondylar tibial plateau fracture (Schatzker type III) with tibial shaft fracture which admitted to our department and discussed the efficacy of using intramedullary nails and plates in the treatment of these fractures. Case presentation A 78-year-old woman with an old unicondylar tibial plateau fracture combined with tibial shaft fracture was presented in this case. Using an intramedullary nail combined with a plate to achieve good results. Clinical discussion This case represents a rare case of an unicondylar tibial plateau fracture with a tibial shaft fracture. In this case, the tibial plateau fracture was first incised and internally fixed with a 9-hole plate across the fracture line of the tibial shaft, followed by fixing the tibial shaft fracture with an intramedullary nail. This treatment helped us successfully reset the unicondylar tibial plateau fracture with tibial shaft fracture and provided a satisfactory outcome for the patient. Conclusion Using intramedullary nails combined with plates to treat unicondylar tibial plateau fractures with tibial shaft fractures allowed for a predictable healing result. Highlights • Unicondylar tibial plateau fractures with tibial shaft fractures are extremely rare in the elderly.• Traditional double plate internal fixation seriously affected soft tissue and bone healing.• The use of plates in combination with intramedullary nails can reduce the destruction of soft tissue and fix both the tibial plateau and the tibial shaft.
