Purpose of study. The aim of this study is to evaluate the role of low intensity pulsed ultrasound, Exogen in the treatment of delayed and non unions. Methodology: We conducted a retrospective study of 292 patients who has had Exogen treatment for delayed and non union from 2005 to 2009. Patient's age, sex, associated co morbidities, smoking history, medications, type of fractures (open/closed), infection and site of fractures were sought for. 271 patients' data (228 delayed and 43 non unions) were available during the study with mean age of 53.5 yrs. Exogen therapy was initiated at 3–4 months for delayed unions and 6–12 months for non unions in 61 tibia (15 open); 31 femur (2 open); 20 scaphoid; 38 5th metatarsal; 31 ankle (2 open); 17 ulna (1 open); 15 radius (3 open); 29 humerus (2 open); 16 clavicles; 6 olecranon; 4 pilon (2 open) and 2 metacarpal fractures. Discussion. Union was achieved in 196 patients (72.3%) of which 11 (5.6%) were smokers. In 73 (26.9 %) patients union was not achieved of which 53 (72 %) were smokers. The mean healing timing after application of Exogen was 16 weeks for delayed union and 26.6 weeks for non union. 5 (31.2%) pt out of 16 in the DM group went into non union. Conclusion. In our study we found an accelerated union rate with Exogen therapy in delayed union, however smoking is a negative predictor for bone healing, which appears to be unaltered despite Exogen therapy(p=0.0032). Prescribing Exogen therapy early may be potentially beneficial to prevent an established non union

Aims. Following the introduction of national standards in 2009, most major paediatric trauma is now triaged to specialist units offering combined orthopaedic and plastic surgical expertise. We investigated the management of open tibia fractures at a paediatric trauma centre, primarily reporting the risk of infection and rate of union. Patients and Methods. A retrospective review was performed on 61 children who between 2007 and 2015 presented with an open tibia fracture. Their mean age was nine years (2 to 16) and the median follow-up was ten months (interquartile range 5 to 18). Management involved IV antibiotics, early debridement and combined treatment of the skeletal and soft-tissue injuries in line with standards proposed by the British Orthopaedic Association. Results. There were 36 diaphyseal fractures and 25 distal tibial fractures. Of the distal fractures, eight involved the physis. Motor vehicle collisions accounted for two thirds of the injuries and 38 patients (62%) arrived outside of normal working hours. The initial method of stabilisation comprised: casting in nine cases (15%); elastic nailing in 19 (31%); Kirschner (K)-wiring in 13 (21%); intramedullary nailing in one (2%); open reduction and plate fixation in four (7%); and external fixation in 15 (25%). Wound management comprised: primary wound closure in 24 (39%), delayed primary closure in 11 (18%), split skin graft (SSG) in eight (13%), local flap with SSG in 17 (28%) and a free flap in one. A total of 43 fractures (70%) were Gustilo-Anderson grade III. There were four superficial (6.6%) and three (4.9%) deep infections. Two deep infections occurred following open reduction and plate fixation and the third after K-wire fixation of a distal fracture. No patient who underwent primary wound closure developed an infection. All the fractures united, although nine patients required revision of a mono-lateral to circular frame for delayed union (two) or for altered alignment or length (seven). The mean time to union was two weeks longer in diaphyseal fractures than in distal fractures (13 weeks versus 10.8 weeks, p = 0.016). Children aged > 12 years had a significantly longer time to union than those aged < 12 years (16.3 weeks versus 11.4 weeks, p = 0.045). The length of stay in hospital for patients with a Gustilo-Anderson grade IIIB fracture was twice as long as for less severe injuries. . Conclusion. Fractures in children heal better than those in adults. Based on our experience of deep infection we discourage the use of internal fixation with a plate for open tibial fractures in children. We advocate aggressive initial wound debridement in theatre with early definitive combined orthopaedic and plastic surgery in order to obtain skeletal stabilisation and soft-tissue cover.

Aim. To study the results of using recombinant human bone morphogenic protein-2 (rhBMP-2) to achieve bone union in children with complex orthopaedic problems including skeletal dysplasia, congenital limb deficiencies and complex trauma. Materials & Methods. Between November 2006 to April 2010, rhBMP-2 was used to achieve bone healing in a total of 19 children. The indications were delayed union or non-union in 16 long bones where previous surgeries had failed and 4 posterior spinal fusions. All children had underlying complex orthopaedic problems predisposing them to delayed bone healing. The average age at the time of surgery was 13 years and 8 months (Range: From 4 years to 19 years and 4 months). There were 7 boys and 12 girls. Results. Average follow-up period was 9.6 months (Range: From 3 months to 2 years and 2 months). Out of the 16 long bone non-unions treated with rhBMP-2, 13 united without further interventions but 3 required further intervention. The average time for clinical union was 10 weeks (Range: from 6 weeks to 18 weeks). The average time for radiological union was 15 weeks (Range: from 7 weeks to 27 weeks). Two children who underwent instrumented posterior spinal fusion and two children who underwent uninstrumented spinal fusion achieved radiologically evident spinal fusion at an average of 16 weeks. No local or systemic complications attributable to BMP were noted in any of the children. Conclusions. rhBMP-2 can be used successfully to achieve bone healing in long bone nonunion and delayed union and posterior spinal fusion in children with complex orthopaedic problems including skeletal dysplasia, congenital limb deficiencies and complex trauma. Its use in children has shown no unwanted effects in the short term. Significance. rhBMP-2 has been approved by Food and Drug Administration (FDA) as a bone graft substitute in adults. Its use in adults has been widely reported but there are only a few case reports of its use in children. This study shows that rhBMP-2 can be safely

Statement of purpose of study: To determine how effective Flexible Intramedullary Nails are in treating tibial and femoral fractures in adolescents. Summary of Methods used: Retrospective review of consecutive adolescent patients treated over a seven year period with Flexible Intramedullary Nails for tibial and femoral fractures. Statement of Conclusion: We conclude that the higher than expected rates of malunion and delayed union suggest that other treatments should be considered when treating adolescents with unstable tibial or femoral fractures. Introduction Flexible intramedullary nails (FIN) are increasingly used in the management of paediatric tibial and femoral fractures. Recently, concerns have been raised regarding the use of FIN in older children. The aim of this study was to determine how effective FIN's are in treating tibial and femoral fractures in adolescents. Methods Hospital records were used to identify all patients aged 11 years or older under going FIN for tibial and femoral fractures between 2003 and 2009. Radiographs and case notes were reviewed to identify complications. Results 35 consecutive adolescent patients underwent FIN for tibial (n=21) and femoral fractures (n=15) with a mean age of 12.9 years. 2 femoral and 9 tibial fractures were open. Eight patients sustained multiple injuries. Mean radiographic follow up was 29 weeks. 60% (n=9) and 38% (n=9) of femoral and tibial fractures respectively malunited. Fracture severity was associated with increased malunion for both tibial and femoral fractures (P=0.046 and P=0.044 respectively). There were no cases of non-union. 2 femoral fractures took longer than 20 weeks to unite and 7 tibial fractures took longer than 16 weeks to unite. One patient developed post operative compartment syndrome, one patient developed deep infection and two patients were treated with post operative traction for loss of fracture position. Discussion Previous publications from multiple centres, including ours, have demonstrated excellent results of FIN for tibial and femoral fractures in the general paediatric population. However, concerns have recently been raised about the use of FIN in older, heavier children and with unstable fracture patterns. This is the first published series of adolescent patients undergoing FIN. We conclude that the higher than expected rates of malunion and delayed union suggest that other treatments should be considered when treating adolescents with unstable tibial or femoral fractures

We reviewed 15 patients, nine girls and six boys, with chronic anterior dislocation of the radial head which was treated by ulnar osteotomy, external fixation and open reconstruction of the elbow joint but without repair of the annular ligament. Their mean age was 9.5 years (5 to 15) and the mean interval between the injury and reconstruction was 22 months (2 months to 7 years). All radial heads remained reduced at a mean follow-up of 20 months (6 months to 5 years). Normal ranges of movement for flexion, extension, pronation and supination were unchanged in 96.1% (49/51) and worse in 3.9% (2/51). Limited ranges of movement were improved in 77.8% (7/9), unchanged in 11% (1/9) and further decreased in 11% (1/9).There were two superficial pin-track infections and two cases of delayed union but with no serious complications. Reconstruction of the radiocapitellar joint is easier using external fixation since accurate correction of the ulna can be determined empirically and active functional exercises started immediately. Only patients with a radial head of normal shape were selected for treatment by this method

We report our experience of the use of callus distraction with a monolateral fixator for the treatment of acquired radial club-hand deformity after osteomyelitis. Between 1994 and 2004, 13 patients with a mean age of eight years (4 to 15) were treated by callus distraction with a monolateral fixator after a preliminary period of at least four weeks in a corrective short-arm cast. All patients achieved bony union and were satisfied with the functional and cosmetic outcome. There were no major complications, but three patients required cancellous bone grafting at the docking site for delayed union. Local treatment and oral antibiotics were required for pin-site infection in six patients. There were no deep infection or recurrence of osteomyelitis

We present the results of 90 consecutive children with displaced fractures of the forearm treated by elastic stable intramedullary nailing with a mean follow-up of 6.6 months (2.0 to 17.6). Eight (9%) had open fractures and 77 (86%) had sustained a fracture of both bones. The operations were performed by orthopaedic trainees in 78 patients (86%). All fractures healed at a mean of 2.9 months (1.1 to 8.7). There was one case of delayed union of an ulnar fracture. An excellent or good functional outcome was achieved in 76 patients (84%). There was no statistical difference detected when the grade of operating surgeon, age of the patient and the diaphyseal level of the fracture were correlated with the outcome. A limited open reduction was required in 40 fractures (44%). Complications included seven cases of problematic wounds, two transient palsies of the superficial radial nerve and one case each of malunion and a post-operative compartment syndrome. At final follow-up, all children were pain-free and without limitation of sport and play activities. Our findings indicate that the functional outcome following paediatric fractures of the forearm treated by elastic stable intramedullary nailing is good, without the need for anatomical restoration of the radial bow

Purpose. This study aims to report the radiological corrections achieved and complication profile of Peri-Acetabular Osteotomy (PAO) undertaken through the minimally invasive approach. Method. 106 PAOs were performed in 103 patients, by senior author, using a minimally invasive approach from 2007 to 2015. Pre- and post-operative radiographs were reviewed and the degree of acetabular re-orientation was analysed. Case notes were examined retrospectively to identify haemoglobin levels and complications across two sites. Results. 73 female and 30 male patients underwent PAO procedures at a mean age of 25 years (9 – 54 years). Follow-up ranged from 23 to 80 months. 26 patients had concurrent proximal femoral osteotomies. Pre-operatively the average centre edge angle measured −1.6° with the vertical centre edge angle reading −0.2°. Post-operative radiographs confirmed correction of these values to 30° and 25.1° respectively. Sharp's angle also improved from a mean value of 49.5° to 33.3°. Review of the Tönnis angle showed correction from an average of 24.1° to 6.9°. The average drop in haemoglobin was calculated as 39 g/L with around 50 % of the patients requiring a peri-operative blood transfusion. The mean preoperative modified Harris Hip Score was 65.6 (Standard deviation σ=11.6) and the same at follow-up was 84.1(σ=11.5). Our outcome scores were comparable with recent PAO series including that of Gray et al. 10 patients reported lateral cutaneous nerve hypoesthesia and 9 had problematic screws. 2 patients underwent washouts as treatment for haematoma and infection. 4 patients had delayed union of the pubic osteotomy and a further 8 patients had asymptomatic osteotomy non-union. One posterior column non-union necessitated plating. One painful fibrous union of ischium and 3 inferior pubic rami stress fractures. Conclusion. This study shows that minimally invasive approach has favourable outcomes and that it is feasible to achieve adequate correction with results/complication profile comparable to traditional approach

A femoral fracture in an adolescent is a significant injury. It is generally agreed that operative fixation is the treatment of choice and rigid intramedullary nailing is a surgical treatment option. We present on experience of treating adolescent femoral fractures using a lateral entry intramedullary nail. We reviewed 15 femoral fractures in 13 children who we treated in our unit between 2011 and 2014. Two patients had bilateral fractures (non-simultaneous). Data collected included patient demographics, mechanism of injury, type of fracture, associated injuries, size of nail, time to unite and complications. The mean age of the patients at time of surgery was 12 years (range 10–15). There were 7 male and 6 female. 10 fractures were caused by a fall whilst 5 were due to road traffic collisions (RTC). 8 fractures involved the middle third, 2 of theses were open fractures and were caused by a RTC. The remaining 7 involved the proximal third of the femur. The mean time to radiological union was 3.4 months (range 2.5–5) in 14 fractures. One patient had a delayed union that required bone grafting and united fully at 7.5 months post injury. The only other complications were a broken proximal locking screw in one patient and an undisplaced femoral neck fracture in another patient. These complications did not compromise the outcome. No patients had infection or developed avascular necroses at the latest follow up. Intramedullary nailing of adolescent femoral fractures using the lateral entry point is safe and effective

We report the radiological outcomes, and short-term clinical results, of 47 periacetabular osteotomies undertaken through both the traditional bikini incision, and a minimally invasive approach. 47 periacetabular osteotomies have been undertaken in 45 patients, by the senior author, between 2005 and 2013. There were 10 male and 35 female patients. The mean age at operation was 28.2 years. Since 2010 surgery has been performed through a 7-cm skin incision (31 hips), an incision coined as minimally invasive by Søballe et al when they described their trans-sartorial approach for acetabular surgery. Clinical data was collected prospectively; primary outcome measures included the young adult hip score and the hip disability and osteoarthritis outcome score. Pre- and post-operative radiographs were analysed for achieved acetabular reorientation. At the time of follow-up the median young adult hip score had improved significantly from pre-operative values. Mean scores were 35.4 pre-operatively, and 64.25 post-operatively. Improvement in the anterior and lateral centre-edge angle was 32 and 32.9 degrees respectively through a traditional incision, and 27.1 and 30 degrees through the minimally invasive approach (p>0.05). No major complications occurred in any patient. Four patients complained of lateral cutaneous nerve hypoaesthesia, in two patients there was delayed union of the pubic osteotomy and in one non-union. Two patients have gone on to total hip replacement. The minimally invasive approach is safe and allows for accurate reorientation of the acetabulum whilst minimizing tissue damage. The scar is cosmetically appealing to patients, especially the predominantly female group treated with this condition. We did not see the evidence of reduced surgical stay that has been reported by other groups utilizing a minimally invasive approach. Level of evidence: II

Purpose of Study. To evaluate the results of using external fixation to stabilise femoral derotation osteotomy involved in DDH surgery. Methods and results. A retrospective analysis was performed on 44 patients undergoing 48 femoral osteotomies for DDH surgery between the years 2001 and 2009 by a single surgeon (senior author MC). The external fixator was used either during the primary procedure involving femoral shortening to aid in hip reduction (4 patients) or to correct femoral malrotation in a reduced hip as a secondary procedure(40 patients). As the external fixator frame was within the hip spica it was not a cause of concern to the parents or the child. There was no evidence of any pin tract infection and all patients eventually progressed to satisfactory bony union. One patient had delayed union which was treated successfully with conservative management and one patient had a malunion requiring a further osteotomy and extended treatment with the external fixator. Conclusion. External fixation is a viable alternative for the traditional internal fixation used for femoral osteotomy involving DDH Surgery. Our study has shown that it produces satisfactory results with minimal complications. Apart from minimising tissue scarring in the muscle and subcutaneous planes, it gives a cosmetically better scar. If there is further need for revision surgery it provides healthy tissue planes for dissection. Furthermore it eliminates the need for additional surgery required for removal of plates

We treated 22 children with a supracondylar fracture of the humerus and an ipsilateral fracture of the forearm by closed reduction and percutaneous fixation. There were four Gartland type-II and 18 Gartland type-III supracondylar fractures of the humerus. There were fractures of both bones of the forearm in 16 and of the radius in six. Both the supracondylar and the distal forearm fractures were treated by closed reduction and percutaneous fixation. The mean follow-up time was 38.6 months. At the latest follow-up there were 21 excellent or good results and one fair result. There were no cases of delayed union, nonunion or malunion. Five nerve injuries were diagnosed on admission and all recovered spontaneously within eight weeks. No patient developed a compartment syndrome

Purpose. A review of the role of external fixators in paediatric trauma at The Royal London Hospital Trauma and Orthopaedic Department. Methods. Retrospective study between 2004 and 2010 reviewing traumatic bone injuries that required initial management with an external fixator. Information was collected through the patients' medical documents and radiographs. Results. In total twenty-seven patients (15 male:12 female, mean age 11, age range 7-15) were initially treated with external fixators over the six year period. The injured bones included 18 tibias, 5 femurs, 2 humeri, 2 radius/ulna, 2 phalanges and 1 wrist. Three patients had two fractures requiring external fixators. Four patients had associated head injuries. Indications included twenty –one open fractures (3 Gustilo type 2, 6 Gustilo type 3A, 12 Gustilo type 3B), seven closed fractures in poly-trauma patients and two closed severely comminuted fractures. Ten fractures were treated with the external fixator as the definitive treatment, fourteen had application of cast following removal of the external fixator and six were converted to internal fixation. Twenty-eight Linear frames were applied (23 Hoffman IIs, 5 Compact Hoffmans) and two circular frames. Mean duration of frame stabilisation was 8 weeks (range 1-16 weeks). Complications included 2 pin site infections successfully treated with antibiotics, 2 patients with hypertrophic scars, 2 leg length discrepancies secondary to bone loss, 2 patients had delayed union and 2 patients had a lower limb deformity requiring intervention, one for adjustment of frame and the other for correction osteotomy with circular frame. Conclusion. The use of external fixators has an important role to play in the management of open fractures and poly-trauma paediatric patients

Aims

Open tibial fractures are limb-threatening injuries. While limb loss is rare in children, deep infection and nonunion rates of up to 15% and 8% are reported, respectively. We manage these injuries in a similar manner to those in adults, with a combined orthoplastic approach, often involving the use of vascularised free flaps. We report the orthopaedic and plastic surgical outcomes of a consecutive series of patients over a five-year period, which includes the largest cohort of free flaps for trauma in children to date.

Aims

Delayed diagnosis is a well-known complication of a Monteggia fracture-dislocation. If left untreated, the dislocated radial head later becomes symptomatic. The purposes of this study were firstly, to evaluate the clinical and radiological results of open reduction of the radial head and secondly, to identify the factors that may affect the outcome of this procedure.

Aims

The aim of this study was to report the clinical, functional and radiological outcomes of children and adolescents with tibial fractures treated using the Ilizarov method.

The traditional techniques involving an oblique tunnel or triangular wedge resection to approach a central or mixed-type physeal bar are hindered by poor visualisation of the bar. This may be overcome by a complete transverse osteotomy at the metaphysis near the growth plate or a direct vertical approach to the bar. Ilizarov external fixation using small wires allows firm fixation of the short physis-bearing fragment, and can also correct an associated angular deformity and permit limb lengthening.

We accurately approached and successfully excised ten central- or mixed-type bars; six in the distal femur, two in the proximal tibia and two in the distal tibia, without damaging the uninvolved physis, and corrected the associated angular deformity and leg-length discrepancy. Callus formation was slightly delayed because of periosteal elevation and stretching during resection of the bar. The resultant resection of the bar was satisfactory in seven patients and fair in three as assessed using a by a modified Williamson–Staheli classification.

A percutaneous supramalleolar osteotomy with multiple drill holes and closed osteoclasis was used to correct rotational deformities of the tibia in patients with cerebral palsy. The technique is described and the results in 247 limbs (160 patients) are reported. The mean age at the time of surgery was 10.7 years (4 to 20). The radiographs were analysed for time to union, loss of correction, and angulation at the site of the osteotomy.

Bone healing was obtained in all patients except one in a mean period of seven weeks (5 to 12). Malunion after loss of reduction at the site of the osteotomy developed in one tibia.

Percutaneous supramalleolar osteotomy of the tibia is a safe and simple surgical procedure.

Flexible intramedullary nailing is gaining popularity as an effective method of treating long-bone fractures in children.

We retrospectively reviewed the records and radiographs of 56 unstable fractures of the tibia in 54 children treated between March 1997 and May 2005. All were followed up for at least two months after the removal of the nails.

Of the 56 tibial fractures, 13 were open. There were no nonunions. The mean time to clinical and radiological union was ten weeks. Complications included residual angulation of the tibia, leg-length discrepancy, deep infection and failures of fixation. All achieved an excellent functional outcome.

We conclude that flexible intramedullary fixation is an easy and effective method of management of both open and closed unstable fractures of the tibia in children.

Between 2005 and 2010 ten consecutive children with high-energy open diaphyseal tibial fractures were treated by early reduction and application of a programmable circular external fixator. They were all male with a mean age of 11.5 years (5.2 to 15.4), and they were followed for a mean of 34.5 months (6 to 77). Full weight-bearing was allowed immediately post-operatively. The mean time from application to removal of the frame was 16 weeks (12 to 21). The mean deformity following removal of the frame was 0.15° (0° to 1.5°) of coronal angulation, 0.2° (0° to 2°) sagittal angulation, 1.1 mm (0 to 10) coronal translation, and 0.5 mm (0 to 2) sagittal translation. All patients achieved consolidated bony union and satisfactory wound healing. There were no cases of delayed or nonunion, compartment syndrome or neurovascular injury. Four patients had a mild superficial pin site infection; all settled with a single course of oral antibiotics. No patient had a deep infection or re-fracture following removal of the frame. The time to union was comparable with, or better than, other published methods of stabilisation for these injuries. The stable fixator configuration not only facilitates management of the accompanying soft-tissue injury but enables anatomical post-injury alignment, which is important in view of the limited remodelling potential of the tibia in children aged > ten years. Where appropriate expertise exists, we recommend this technique for the management of high-energy open tibial fractures in children.
