Aims. Preserving growth following limb-salvage surgery of the upper
limb in children remains a challenge. Vascularized autografts may
provide rapid biological incorporation with the potential for growth
and longevity. In this study, we aimed to describe the outcomes
following proximal humeral reconstruction with a vascularized fibular
epiphyseal transfer in children with a primary sarcoma of bone.
We also aimed to quantify the hypertrophy of the graft and the annual
growth, and to determine the functional outcomes of the neoglenofibular
joint. Patients and Methods. We retrospectively analyzed 11 patients who underwent this procedure
for a primary bone tumour of the proximal humerus between 2004 and
2015. Six had Ewing’s sarcoma and five had osteosarcoma. Their mean
age at the time of surgery was five years (two to eight). The mean
follow-up was 5.2 years (1 to 12.2). Results. The overall survival at five and ten years was 91% (confidence
interval (CI) 95% 75% to 100%). At the time of the final review,
ten patients were alive. One with local recurrence and metastasis
died one-year post-operatively. Complications included seven fractures,
four transient nerve palsies, and two patients developed avascular
necrosis of the graft. All the fractures presented within the first
postoperative year and united with conservative management. One
patient had two further operations for a slipped fibular epiphysis
of the autograft, and a hemi-epiphysiodesis for lateral tibial physeal
arrest. Hypertrophy and axial growth were evident in nine patients
who did not have avascular necrosis of the graft. The mean hypertrophy
index was 65% (55% to 82%), and the mean growth was 4.6 mm per annum
(2.4 to 7.6) in these nine grafts. At final follow-up, the mean
modified functional Musculoskeletal Tumour Society score was 77%
(63% to 83%) and the mean Toronto Extremity Salvage Score (TESS)
was 84% (65% to 94%). Conclusion. Vascularized fibular epiphyseal transfer preserves function and
growth in young children following excision of the proximal humerus
for a
Between 1990 and 1998 we saw 21 children with primary subacute haematogenous osteomyelitis. Pain, swelling and a limp had been present for two to 12 weeks with little functional impairment. Laboratory tests were non-contributory. The lesions were classified radiologically into metaphyseal, diaphyseal, epiphyseal and vertebral. There were 24 sites involved, with most (20) being in the tibia; 17 lesions were in the diaphysis, five in the metaphysis and two in the epiphysis. The diagnosis was confirmed histologically in all cases. Staphylococcus aureus was cultured in six patients. Healing occurred in all patients after treatment with antibiotics for six weeks and radiological improvement was seen after three to six months. Subacute osteomyelitis develops as a result of increased host resistance and decreased bacterial virulence. The radiological features can mimic various benign or

Type BI rotationplasty is currently indicated for children with tumours of the proximal femur whereas type BIIIa rotationplasty is reserved for those in which the entire femur has to be removed. Our aim was to compare these two types of rotationplasty and determine whether the knee should be preserved in children with tumours of the proximal femur. We compared the post-operative complications, oncological outcome, range of movement, Enneking score and radiographs of six children, who had undergone type BI rotationplasty with those of 12 who had undergone type BIIIa rotationplasty. Patients with type BI rotationplasty had a mean Enneking score of 21.6 compared with 24.4 in those with type BIIIa rotationplasty, and worse mean results in all of the parameters investigated. We conclude that type BI rotationplasty has a worse functional outcome and more complications than type BIIIa rotationplasty in children under the age of ten years.
