The purpose of the study was to establish an algorithm for the treatment of pathological fractures in children.

Pathological fractures can compromise radiographic and histological diagnosis. The need for histological diagnosis and indications for surgical treatment are not clearly defined.

We reviewed our Centre’s Tumour Registry records of children who presented over the past 7 years with a fracture as the first manifestation of primary bone pathology. There were 23 patients (average age 12 years and 2 months).

There were 9 fractures through simple bone cysts, all treated conservatively initially. All patients were subsequently treated with needle biopsy and bone marrow injection. Three patients suffered refracture and underwent flexible intramedullary nail fixation.

There were 5 cases of fibrous dysplasia. Histological diagnosis was obtained in all cases, followed by prophylactic intramedullary nailing in 3 patients.

There were 2 patients with giant cell tumour, 3 with aneurysmal bone cyst and one with chondroblastoma. Histological diagnosis preceded curettage and grafting in all cases.

Finally, there were 3 patients with Ewing’s sarcoma of the femur. One underwent palliative intramedullary nailing for extensive local disease. The second patient was treated conservatively initially. She subsequently underwent segmental resection and vascularised fibular graft. The third patient underwent internal fixation in another unit for what was considered to be a benign lesion. The histological diagnosis of Ewing’s sarcoma was based on intra-operative specimens. Definitive surgery required wide resection and prosthetic replacement.

We recommend that primary fixation of pathological fractures should be avoided until histological diagnosis is obtained. All lesions should be appropriately imaged and biopsied if aggressive characteristics are present. However, if radiographic appearances are reassuringly benign, biopsy can be delayed until conservative fracture management is completed. Definitive treatment of benign lesions with protective intramedullary nailing or curettage and grafting can follow frozen section under the same anaesthetic.

Objective: To assess whether Webb Morley Instrumentation had satisfactory long term results.

Design: A retrospective review of 52 patients who underwent fusion and instrumentation with Webb Morley Instrumentation between 1991–1997.

Subjects: 52 patients were reviewed, 32 patients with idiopathic scoliosis who underwent isolated anterior fusion, 19 patients with neuromuscular scoliosis who underwent anterior and posterior surgery.

Outcome measures: Preoperative and postoperative radiographs, ISIS scans, and patient review. The in-patient notes were assessed for duration of surgery, blood loss, hospital stay and complications. Correction of Cobb angle and union were assessed.

Results: In the idiopathic group Cobb angle improved by 57%, apical rotation by 36% and tilt angle by 56%. There were no major complications and all united. The implant has a tendency to kyphose the spine, and an average of 7 degrees of kyphosis was seen across the implant. In the neuromuscular group Cobb angle improved by 52%, apical rotation by 21% and tilt angle by 57%. There was one asymptomatic pseudarthrosis, two rod breakages and two posterior rod dissociations. Only one patient complained of significant back pain.

Conclusions: Webb Morley instrumentation offers results as good as most other anterior implant systems. The flexibility of the rods may be a relative advantage, with a high union rate. Although the implant tends to kyphose the spine this has not been a problem clinically at follow-up of 4-11 years. This may help in design of future implants.
