Flexible Intramedullary Nailing for Unicameral Bone Cyst of Humerus in Children: A Case Series

Introduction: Unicameral bone cyst is benign fluid-filled lesions in pediatric long bones before skeletal maturity, most commonly in the proximal humerus. These are diagnosed as an incidental finding where the child presents with a pathological fracture.

Aim: Purpose of this study is to evaluate the outcome of treating unicameral bone cyst with or without pathological fracture by flexible intramedullary nailing viz., TENS.

Methods: During the period of June 2015 to June 2019, 13 cases of a paediatric unicameral bone cyst located in proximal 1/3rd of humerus admitted to Bapuji hospital and Chigatteri general hospital, J.J.M medical college, Davangere. Mean age was 9 years. 8 cases presented with pathological fracture.

Results: Out of 13 cases 9 patients had complete healing of cyst at 12 months follow-up, 3 patients had a residual cyst and 1 patient developed recurrence after initial healing response.

Conclusion: Titanium intramedullary nailing is a safe and efficient procedure for unicameral bone cyst as it provides immediate mechanical stability and also cyst decompression allowing early mobilization and return to their daily activities.
