A less invasive surgical treatment of clubfoot is increasingly considered, it aims to limit extensive exposure, to improve the functional and cosmetic outcome and to lower the risk of stiffness and recurrence of the deformity. The Ponseti method consists in an original casting technique followed, only in the most resistant clubfeet, by a percutaneous Achilles tenotomy. Critical decision is the selection of the clubfeet which needs tenotomy. Purpose of this study was to determine if ultrasound assessment of clubfoot may be helpful in making surgical decision.

MATERIAL AND Methods: 98 newborns with 122 congenital clubfeet were treated by the Ponseti casting technique from mid-2000 to June 2006. According to Manes classification, there were 20 mild, 47 moderate and 55 severe clubfeet. After 3 to 8 weeks of casting, clubfeet candidate to surgery underwent sonographic assessment according to the original technique previously published by the authors. On the sagittal posterior plane the R.O.M. of the ankle and subtalar joints was stated both in neutral position and under manipulation. No surgery was performed in clubfeet with normal sonographic dorsiflexion, percutaneous tenotomy was done in clubfeet with mild limited sonographic dorsiflexion and more extensive posterior release (tendon Z-lengthening and posterior cut of ankle and subtalar joint) was performed in clubfeet with most evident sonographic persistent equinus and anterior dislodgment of the talus in the ankle mortise. The R.O.M. was checked again by ultrasound at the end of treatment. According to Ponseti method a Denis Browne bar, with clubfoot 60° externally rotated, was worn full time until the walking age.

Results: 35/122 clubfeet (28,6%) were treated conservatively (all the 20 mild and 15/47 of moderate deformities), 87/122 (71,4%) surgically (32/47 of moderate deformities and all the 55 severe deformities). On the basis of the dynamic ultrasound evaluation 38 clubfeet underwent simple tenotomy and 49 ones underwent extensive posterior release. At the end of the casting normal dorsiflexion was documented by ultrasound in 72 (82,7%) of the operated feet.

Conclusions: The need of surgery in the Ponseti casting technique shows a great variability in Literature. These controversial data are probably due not only to the different confidence in the Ponseti method, but also to the different criteria used in evaluating the correction obtained by casting. Ultrasound assessment of the deformity gives objective qualitative and quantitative information about the restoration of the physiological dorsiflexion and articular biomechanics. On the basis of this simple, non invasive and widely available procedure the surgeon can evaluate the effectiveness of the serial casting and may be able to establish and graduate the need of corrective surgery.

Introduction: In temperate places pyomyositis is very uncommon in children and adolescents. West European and North American Literature about is relatively poor (104 articles from 1998 to nowadays and most of these papers are case-rep orts). S. Aureus is the etiologic agent in 90% of cases. Muscle of the thighs and hips are the most frequent localisation and severe complications are observed in 10% of cases.

Material and Methods: We reviewed all patients affected by primary pyomyositis and admitted in our Department from 1995 to nowadays. Age, sex, history and clinical findings, general and local risk factors were reported. X-rays, Ultrasonography, MRI, Scintigraphy, Haematological investigation and culture were considered in order to state the imaging and laboratory findings of the disease.

Result: Pyomyositis was diagnosed in three males, aged 11, 13 and 16. There was no evidence of medical or familiar risk factors. Soleus, Otturatorius and Psoas muscles were respectively involved. In all cases fever, local signs of inflammation and pain, neutrophylic leukocytosis, increased ESR and CRP levels were present. Blood culture was positive in one case. Standard X-Rays were normal in all cases. Ultrasound scan, RMI and Scintigraphy were positive but non-specific in all cases. 2 cases underwent to surgical drainage and a 3 weeks antibiotic therapy; 1 case resolved performing only medical treatment (5 weeks of antibiotic). All patients showed complete clinical, haematological, and RMI recovered without reliquates.

Conclusions: Pyomyositis is uncommon in temperate climate and it may be easy misdiagnosed at the onset. In our patients the mean time from onset of symptoms to diagnosis was 10 days. History and clinical examination might be evocative, but there are no pathognomonic haematological or radiological findings so that diagnosis is often the result of extensive and wide considerations. Pyomyositis should be suspected in any unclear septic condition of the musculoskeletal apparatus. High index of suspicion, prompt diagnosis, and early treatment can prevent complications and allow the recovery of this potentially life-threatening disease.

Renal failure in children is associated with a wide range of musculoskeletal disorders such as osteonecrosis, stress fractures, brown tumours, epiphysiolysis, joint infections and angular deformities. In this paper the authors report their experience concerning the surgical treatment of the angular deformities of the lower limbs in renal osteodystrophy (RO).

Between 1995 to 2003, 10 children (five girls and five boys) with RO underwent surgical correction of angular deformities of the lower limbs. Of these, seven had femoral osteotomies because of knee deformities (three genu valgum, four genu varum) and three had osteotomies because of tibial angular deformity. The average age at surgery was 5 years (min. 2 years, max. 12 years). Different types of osteosynthesis were used (staples and cast, Ortho-fix and Ilizarov frames) according to the age of the child and the degree and the site of the angular deformities.

All osteotomies healed without complications and the surgical correction was considered appropriate at the end of treatment. At an average follow-up of 4.5 years there was no significant relapse and no need for second surgery.

Simple osteosynthesis (staples and cast) was most appropriate in the youngest children and in mildest deformities (particularly at the distal tibial metaphysis). External devices were more suitable in the oldest children and for genu valgum/varum deformities. To optimise the time of consolidation close collaboration with the paediatricians is required in order to perform surgery under the best metabolic conditions (elevation of the serum alkaline phosphatase concentration above 500/l is a good marker of bone metabolic healthy).

Purpose: To elucidate the pathomorphology of the unossified clubfoot and to monitor the progressive correction of the deformity during treatment, the authors introduce a standardized sonographic assessment of the foot at birth and at the end of both conservative and surgical corrective procedures.

Methods: 42 congenital clubfeet and 42 normal newborns were documented by ultrasound using a 7,5/10 MHz linear arrays probe with direct contact. Clubfeet were documented in the position of spontaneous alignment and during passive manual correction at the admission and at the end of both conservative and surgical treatment. Five standard ultrasound planes were used: sagittal posterior, sagittal anterior, coronal lateral, transversal and coronal medial plane.

Results: On the sagittal posterior plane the progressive gain of the dorsiflexion during the different steps of the treatment was documented measuring the distance between the distal tibial metaphysis and the calcaneal apophysis. In clubfeet, looking at the ossification centre of the talus, both its forfeit of domicile in the ankle mortise and its right positioning after treatment can be showed. On the sagittal anterior plane and on the transversal plane the medial displacement of the navicular is documented. The normalisation of the anatomic alignment of the navicular is well documented by these planes after appropriate treatment. On coronal lateral plane the relationships between the os calcis and cuboid can be estimated using the calcaneal-cuboid angle. The coronal medial plane exhibited a very low reproducibility in the neonatal clubfoot and it is not reccomended

Conclusions: Ultrasonography it is a very promising technique in the monitoring of clubfoot deformity during treatment. On the sagittal posterior and on the coronal lateral planes strictly quantitative information can be easily deduced while prevalently qualitative information are deduced on the sagittal anterior and on the transversal planes. Ultrasound gives exact and reproducible information concerning the pathomorphology of the not ossified
