The aim of the present study was to assess the outcomes of the induced membrane technique (IMT) for the management of infected segmental bone defects, and to analyze predictive factors associated with unfavourable outcomes. Between May 2012 and December 2020, 203 patients with infected segmental bone defects treated with the IMT were enrolled. The digital medical records of these patients were retrospectively analyzed. Factors associated with unfavourable outcomes were identified through logistic regression analysis.Aims
Methods
To clarify the effectiveness of the induced membrane technique (IMT) using beta-tricalcium phosphate (β-TCP) for reconstruction of segmental bone defects by evaluating clinical and radiological outcomes, and the effect of defect size and operated site on surgical outcomes. A review of the medical records was conducted of consecutive 35 lower limbs (30 males and five females; median age 46 years (interquartile range (IQR) 40 to 61)) treated with IMT using β-TCP between 2014 and 2018. Lower Extremity Functional Score (LEFS) was examined preoperatively and at final follow-up to clarify patient-centered outcomes. Bone healing was assessed radiologically, and time from the second stage to bone healing was also evaluated. Patients were divided into ≥ 50 mm and < 50 mm defect groups and into femoral reconstruction, tibial reconstruction, and ankle arthrodesis groups.Aims
Methods
This study reviews the use of a titanium mesh cage (TMC) as an
adjunct to intramedullary nail or plate reconstruction of an extra-articular
segmental long bone defect. A total of 17 patients (aged 17 to 61 years) treated for a segmental
long bone defect by nail or plate fixation and an adjunctive TMC
were included. The bone defects treated were in the tibia (nine),
femur (six), radius (one), and humerus (one). The mean length of
the segmental bone defect was 8.4 cm (2.2 to 13); the mean length
of the titanium mesh cage was 8.3 cm (2.6 to 13). The clinical and
radiological records of the patients were analyzed retrospectively.Aims
Patients and Methods
Many authors have reported a shorter treatment time when using trifocal bone transport (TFT) rather than bifocal bone transport (BFT) in the management of long segmental tibial bone defects. However, the difference in the incidence of additional procedures, the true complications, and the final results have not been investigated. A total of 86 consecutive patients with a long tibial bone defect (≥ 8 cm), who were treated between January 2008 and January 2015, were retrospectively reviewed. A total of 45 were treated by BFT and 41 by TFT. The median age of the 45 patients in the BFT group was 43 years (interquartile range (IQR) 23 to 54).Aims
Patients and Methods
The aim of this study was to identify risk factors for the failure
of exchange nailing in nonunion of tibial diaphyseal fractures. A cohort of 102 tibial diaphyseal nonunions in 101 patients with
a mean age of 36.9 years (15 to 74) were treated between January
1992 and December 2012 by exchange nailing. Of which 33 (32%) were
initially open injuries. The median time from primary fixation to
exchange nailing was 6.5 months (interquartile range (IQR) 4.3 to
9.8 months). The main outcome measures were union, number of secondary fixation
procedures required to achieve union and time to union. Univariate analysis and multiple regression were used to identify
risk factors for failure to achieve union. Aims
Patients and Methods
We undertook a retrospective study of 50 consecutive patients (41 male, 9 female) with an infected nonunion and bone defect of the femoral shaft who had been treated by radical debridement and distraction osteogenesis. Their mean age was 29.9 years (9 to 58) and they had a mean of 3.8 (2 to 19) previous operations. They were followed for a mean of 5.9 years (2.0 to 19.0). The mean duration of the distraction osteogenesis was 24.5 months (2 to 39). Pin-track infection was observed in all patients. The range of knee movement was reduced and there was a mean residual leg-length discrepancy of 1.9 cm (0 to 8) after treatment. One patient required hip disarticulation to manage intractable sepsis. In all, 13 patients had persistant pain. Bony union was achieved in 49 patients at a mean of 20.7 months (12 to 35). Although distraction osteogenesis is commonly used for the treatment of infected femoral nonunion with bone defects, it is associated with a high rate of complications.
