Four years follow-up after clavicle reconstruction in a child: a case report.

Clavicle reconstruction is a rare operation. In most cases a mid-shaft defect of the clavicle is bridged by using different grafting techniques or musculo-osteous flaps. In some clinical situations where reconstruction is not a suitable option claviculectomy as a salvation procedure has proven to be an acceptable solution. In the paediatric population the challenge of both the cosmetic and the functional result attempting reconstruction of large bone defects is of higher demand. To our knowledge, this is the first case of a successful clavicle reconstruction with a sufficient follow-up using a free vascularised fibula graft in a child. This case provides a technique description, considerations in the paediatric population, an overview of other techniques used, and a long-term follow-up.

Fractures in Children and Adolescents

Fractures of the growing bone require fixation techniques, which preclude any injury to the growth plate regions. This requirement is met by Elastic Stable Intramedullary Nails (ESIN) which are positioned between both metaphyseal regions. Pronounced malposition and/or shortening, open fractures and fractures with impending skin perforation are indications for clavicle nailing in adolescents. Retrograde nailing with two elastic nails, inserted from lateral, is the method of choice for stabilization of humerus fractures. In radial neck fractures with severe tilting of the radial head, a retrograde nail may reduce and fix the head. In Monteggia lesions, the ulna fracture is reduced and fixed with an antegrade nail. Forearm fractures with unacceptable axial deviation are reduced and fixed with one antegrade nail in the ulna and a retrograde nail in the radius. Ascending elastic nailing is done for femur shaft and proximal femur fractures. The medial and lateral entry sites are located above the distal physis. End caps are used to prevent shortening in spiral and multiple segment fractures. Fractures of the distal third of the femur are nailed in a descending technique. The entry sites of two nails are located on the lateral cortex below the greater trochanter. Combined tibia and fibula fractures, open fractures and unstable fracture types such as spiral and multifragmental tibia fractures are good indications for ESIN. Descending nailing is the method of choice. The nail entry points are medially and laterally distal to the apophysis of the proximal tibia. Thorough knowledge of each fracture type, fracture location and age specific healing pattern is necessary for safe and effective treatment of pediatric fractures
