Aim: To report our experience and early results with the Ilizarov pelvic support realignment lengthening osteotomy for complex hip pathology in children.

Material & Methods: Between 1997 & 2004, seven children were treated with this technique and five have completed treatment. The treatment was undertaken for sequelae of DDH in 4 patients and septic arthritis in 1 patient. The median age of the patients was 13(10–17). There were 3 boys and 2 girls. The outcome assessment was performed using the Harris hip score, clinical and radiological parameters.

Results: 4 patients presented with hip instability, shortening of the lower limb, pain and restricted motion. The remaining patient presented with a nonfunctional ankylosis with shortening. The median time between the onset of symptoms and the operation was 3 years (2–5). The median preoperative leg-length discrepancy was 3 cm (2–4.5). The median fixator time was 5 months (3–6). The median follow-up was 24 months (9–72).

Patients had improvement of pain, posture, hip instability, walking ability and limb length discrepancy. The median lengthening of the femur was 3 cm (2–5). The mechanical axis was realigned in all patients. All patients were satisfied with the outcome. Planned secondary contra lateral epiphyseodesis was required to equalise leg length in 2 patients. Complications included a stiff knee (1) that required a Judet quadricepsplasty, premature consolidation (1) that required reosteotomy and knee subluxation (1) that required cross knee stabilisation.

Conclusion: This is a safe and reliable alternative option to joint replacement, Colonna arthroplasty and arthrodesis for the reconstruction of multiply operated complex hip pathology in children.

Aim: To report our experience and early results with flexible nailing for unstable or irreducible displaced proximal humeral fractures in children.

Material & methods: Between 1997 & 2004, 15 children with unstable or irreducible displaced fractures of the proximal humerus were treated with closed/open reduction and flexible IM nailing. There were 10 boys and 5 girls. The median age of the patients was 12.5 years (9–15). Thirteen children had a Salter – Harris II, Neer grade III/IV fracture and 2 children had metaphyseal fractures. The outcome assessment was performed using the shoulder score, clinical and radiological parameters.

Results: All fractures united. None of the patients had a clinically significant malunion/shortening. Three patients had irritation at the nail insertion site. One patient had a transient radial nerve neurapraxia. There were no other operative or postoperative complications. The flexible nails were removed at a median time of 6 months (1.5–10) in 12 patients and 3 patients are awaiting removal. At a median follow-up of 30 months (4–66) all patients had a normal or near normal glenohumeral motion, full strength and all reported regaining full pre-injury functional use of the involved extremity.

Conclusion: Flexible nailing can be used safely to maintain reduction in unstable or irreducible displaced fractures of the proximal humerus and allows early return to normal activities and function with minimal complications. This treatment is also useful in older children who have minimal remodelling potential.

Introduction and Aims: To determine the optimum management of growth arrests secondary to meningococcal septicaemia.

Method: A retrospective study of 28 children treated in children’s hospitals in the UK for long bone deformities caused by growth plate arrests secondary to meningococcal septicaemia.

Results: 28 children (age range four to eight years) with growth arrests of the long bones following meningococcal septicaemia were treated for their bony deformities (a limb length discrepancy or a progressive angular deformity of the upper or lower limb) using the Ilizarov technique. Resection of bony blocks was ineffective in preventing progressive deformities. Limb length discrepancies were treated satisfactorily with equalisation of limb lengths. Angular deformities required ablation of the remaining part of the affected growth plate in order to prevent recurrence. Distal tibial deformities were treated satisfactorily with a transepiphyseal osteotomy. In the upper limb lengthening of either the radius or ulna restored alignment to the wrist. One patient with a growth arrest affecting a tibial amputation stump underwent satisfactory stump realignment and lengthening. Limb lengthening will need to be repeated in younger children, as the deformity will recur with growth until skeletal maturity.

Conclusion: The Ilizarov technique enables satisfactory treatment of growth deformities secondary to meningococcal septicaemia. With peripheral growth plate arrests causing an angular deformity the remaining open growth plate needs to be ablated to prevent recurrence of the angular deformity. Any recurrence will then be a shortening only, which can be treated by further lengthening if required.

We undertook this retrospective study to determine the rate of recurrence and functional outcome after intralesional curettage for chondroblastoma of bone. The factors associated with aggressive behaviour of the tumour were also analysed. We reviewed 53 patients with histologically-proven chondroblastoma who were treated by intralesional curettage in our unit between 1974 and 2000. They were followed up for at least two years to a maximum of 27 years.

Seven (13.2%) had a histologically-proven local recurrence. Three underwent a second intralesional curettage and had no further recurrence. Two had endoprosthetic replacement of the proximal humerus and two underwent below-knee amputation after aggressive local recurrence. One patient had the rare malignant metastatic chondroblastoma and eventually died. The mean Musculoskeletal Tumour Society functional score of the survivors was 94.2%.

We conclude that meticulous intralesional curettage alone can achieve low rates of local recurrence and excellent long-term function.

Aim: To evaluate our results of articulated hip distraction in children with a painful, stiff hip.

Materials & Methods: Between 1988 & 2003, 10 children underwent hip distraction and 7 have completed treatment. The diagnoses were varied, though the presentations were those of pain & stiffness of the hip, poor posture and gait. The Orthofix articulated hip device was used in all patients. The outcome assessment was performed by clinical and radiological review.

Results: The mean age of the patients was 13.7 years (Range 12–17 years). The primary diagnosis was SUFE- 3, Perthes-4, trauma-1, septic arthritis -1, chemotherapy induced -1. The mean fixator time was 12 weeks (range 10–14 weeks). The follow-up period ranged from 4–183 months. Soft tissue releases and joint debridement were done in 6 and 2 patients respectively. Results were good in one, fair in five and poor in one patient. Patients with non-functional ankylosis gained functional position with some increase in range of motion. Grade 2 pin tract infections were noted in 4 patients.

Conclusion: Early results with hip distraction in this difficult, complicated group of patients are promising clinically and radiologically.

Introduction: Meningococcal septicemia is a devastating illness that primarily affects children. Late orthopaedic sequelae, though rare, are being seen more frequently as acute medical management has reduced the initial mortality rate.

Aims: To review the case histories and discuss the management of these children.

Methods: A retrospective review of medical notes and radiographs was undertaken at the participating hospitals. Outcomes assessed included clinical & radiologic outcome, limb length equalization and correction of the mechanical axis.

Results: Between 1990 and 2000, twenty patients aged 2 to7 years presented to the orthopaedic departments of the participating hospitals with late sequelae. On average presentation wasf 4 years (2 – 6) after the acute phase of the disease. The reasons for referral included angular deformity, limb length discrepancy, joint con-tracture or problems with prosthetic fitting. The lower limbs were involved more frequently than the upper limbs. In fourteen children multiple growth plates were affected. Partial growth arrest was the cause of the angular deformity and limb length discrepancy. All twenty children underwent operations for realignment of the mechanical axis and equalization of limb length. Recurrence of the angular deformity was almost universal.

Conclusion: Children who survive meningococcal septicaemia are at risk for developing late orthopaedic sequelae. Lower limbs are more commonly affected with deformities of limb length and axis. We recommend complete ablation of the affected growth plates at the initial surgery to prevent recurrence of the angular deformity. Further limb length equalization procedures can be anticipated. Early recognition and orthopaedic follow-up to skeletal maturity is essential for minimizing the effects of these sequelae.

Aim: The purpose of this retrospective study was to analyse the risk factors, causes, bacteriology of deep infection following extensible endoprosthetic replacement for bone tumours in children and to review our experience in the treatment of 20 patients with infected prostheses.

Materials and methods: 123 patients with extensible endoprostheses were treated between 1983 and 1998. Three types of prostheses, which differed in the lengthening mechanism used, were implanted. 20 of these were diagnosed to have deep infection. Patients were divided into 3 groups: group I- 5 patients were treated with a single stage revision, group II- 13 patients were treated with a two stage revision procedure, group III- 2 patients had a primary amputation. Control of infection was assessed clinically and with inflammatory markers. Function was assessed using the MSTS score.

Results: The overall incidence of infection was 16%. The incidence of infection at the proximal tibia and distal femur was 27% and 14% respectively. Staphylococcus epidermi-dis was the most common organism. The most common clinical features were pain and swelling around the pros-theses. Infection in most cases was immediately preceded by an operative procedure or by distant a focus of infection. The number of operative procedures and the site of the prosthesis were significant risk factors. The success rate was 20% in Group I and 84.6% Group II. Amputation was the salvage procedure of choice for failed revision procedures. The mean MSTS functional score was 83% in patients in whom the infection was controlled.

Conclusion: The incidence of deep infection is high following extensible endoprostheses. The site of the pros-thesis and the number of operative procedures are significant risk factors.

This is a retrospective study of 70 patients with chondroblastoma treated between 1973 to 2000. Of these 70 patients, 53 had their primary procedure performed at our unit in the form of an intralesional curettage. The purpose of this study was to determine the rates of recurrence and the functional outcomes following this technique. Factors associated with aggressive tumour behaviour were also analysed. The patients were followed up for at least 22 months, up to a maximum of 27 years. 6 out of these 53 cases (11. 3%) had a histologically proven local recurrence. Three patients underwent a second intralesional curettage procedure and had no further recurrences. Two patients had endoprosthetic replacement of the proximal humerus and one patient underwent a below knee amputation following aggressive local recurrences. One patient had the rare malignant metastatic chondroblastoma and died eventually. The mean MSTS score was 94. 1%. We conclude that meticulous primary intralesional curettage without any additional procedure can achieve low rates of local recurrence and excellent long-term functional results.

Limb salvage is now customary in the treatment of primary bone tumours. The proximal tibia is a frequent site for these neoplasms but reconstruction, especially in children, is a formidable challenge. We reviewed 20 children with extendible replacements of the proximal tibia, all with a minimum follow-up of five years. Five died from their disease and, of the remaining 15, four had above-knee amputations for complications. Infection occurred in seven patients; in five it was related to the lengthening procedure. Aseptic loosening is inevitable in the younger children and only two have avoided a revision, amputation or other major complication; both were aged 12 years at the time of the initial surgery. Despite this, 11 children are alive with a functioning leg and a mean Musculoskeletal Tumour Society functional score of 83%. The lengthening mechanisms used in our series required extensive open operations. We are now using a simpler, minimally invasive, technique which we hope will decrease the incidence of complications. At present, the use of extendible prostheses of the proximal tibia remains an experimental procedure.
