First metatarsal bone reconstruction using Masquelet’s technique after bone loss in open III B injury

Background: Masquelet technique involves two stages for reconstruction of bony defects. During stage one decontamination and debridement is performed. The bone defect filled by a spacer made cement. After gap around 6 weeks, bio-membrane established the cement spacer. two, removed cancellous autologous graft used to fill space that was previously occupied However, there huge scarcity literature on defects in foot metatarsals, especially open injuries require soft tissue coverage also. Methods: This prospective study involved 25 patients with minimum follow-up 12 months. Masquelet’s reconstruct large metatarsals staged manner. primary outcome variable union consolidation bone. secondary variables included complications functional using Maryland score. Results: One needed below knee amputation extensive infection. Pin site infection commonest indication observed deep table at time second patients. Both re-do new placed which six weeks. Hallux varus deformity final follow-up. Excluding patient amputation, all had mean score 79.45±8.8. Good excellent among 91.66% Conclusions: induced membrane potentially fruitful method deal created fractures feet. due limited sample size lack control group, we recommend scale randomized trials be conducted subject.
