All patients presented signs of neurofibromatosis as café-au-lait stains and family history. Patients with CPF affecting only the radius presented deformity similar to congenital radial club hand. [meeting.handsurgery.org]

• Chills

  The history of the disease revealed that the child initially presented with fever and chills. He was then treated for malaria for a few days, as it is common in endemic areas. [dovepress.com]

• Recurrent Fractures

  However, surgical intervention is required in case of non-union and recurrent fractures. The surgical therapy consists of resection of the diseased segment and bone grafting, followed by internal or external fixation [ 3 ]. [e-aps.org]

• Long Legs

  The Ilizarov fixator was then removed and replaced by a long-leg synthetic cast for an additional 6 weeks to prevent early fracture. The consolidation of the regenerate bone was achieved after 245 days. [dovepress.com]

  The wound was closed in layers and a long leg splint was applied. Three months later, no abnormal changes were noted in X-ray imaging and no clinical wounds were observed ( Figs. 4, 5 ). [e-aps.org]

• Walking Delay

  As the child is not operated before he reaches a certain age, wearing a protective brace before the child has begun walking delays the fracture in bowing and limits the deformity if pseudarthrosis is already present. [boneandspine.com]

This treatment avoids risking injury to the healthy contralateral leg. Additionally, for treatments that do not achieve satisfactory results, other treatment methods are not excluded. [journals.lww.com]

The prognosis is good if the lesion is located only on the fibula, an extension to the tibia has a prognosis similar to type II, Type VI Associated with an intraosseous fibroma or a schwannoma. [boneandspine.com]

Type III cases have a better prognosis. The gross pathology is a bone cyst, and the microscopic findings resemble fibrous dysplasia. After surgical treatment, generally, the older the child the better the prognosis. [scienceopen.com]

The prognosis depends on the aggressiveness and treatment of the intraosseous lesion. [orthopedicnotes.blogspot.com]
