RESUMO
PURPOSE: The aim of the study was to evaluate the accuracy and radiographic outcomes of Canale's method in patients with idiopathic leg-length discrepancy (LLD) following percutaneous epiphysiodesis. The accuracy of two common growth prediction methods was assessed. METHODS: A total of 18 patients with 26 affected bones (eight distal femur, two proximal tibia, five combined) were clinically and radiologically analyzed after reaching skeletal maturity. We compared the final effect of epiphysiodesis at maturity with the expected effect of epiphysiodesis before surgery; these measures were calculated using the Green-Anderson and multiplier methods, respectively. We furthermore compared pre- and postoperative frontal and lateral plane radiographs. RESULTS: The average LLD was 21.2 mm before surgery and 7.9 mm after epiphysiodesis. The final effect of both methods was not significantly different compared with the expected effect of epiphysiodesis before surgery. However, the prediction by the Green-Anderson method was closer to the definitive epiphysiodesis effect. The frontal plane radiographic deformity parameters did not change significantly after epiphysiodesis. The postoperative sagittal plane radiographic deformity parameters were in the normal range. CONCLUSION: The Canale technique is a reliable method to reduce LLD in children. With regards to growth prediction, the Green-Anderson method using bone age seems to be more accurate than the multiplier method using chronological age. However, a relative over-estimation was observed with both methods in several cases, which might result in an insufficient correction. LEVEL OF EVIDENCE: IV, Therapeutic study.
RESUMO
BACKGROUND: The congenital tibia hemimelia, also called tibial deficiency, is a rare disorder with unknown cause, showing many associated abnormalities or varying syndromes. METHODS: The correct diagnosis can be easily established using radiographs and/or magnetic resonance imaging in the postpartum setting. However, treatment may be difficult and needs to take into consideration the given anatomic situation in the knee and ankle joint. CONCLUSION: Prosthetic fitting may be possible in mild cases. Nevertheless, the majority of patients need to undergo surgical reconstruction in order to restore a functional, mobile, and stable knee and ankle joint.

The purpose of this systematic review was to determine the outcome of interphalangeal (IP) joint motion in children undergoing open surgical release, splinting, and passive exercising therapy for the treatment of paediatric trigger thumb. We conducted an online literature search of seven major databases. Only studies with a mean follow-up of at least 12 months were considered for inclusion. Seventeen retrospective studies and one prospective study met all the inclusion criteria. They reported on the results of surgery (634 children, 759 thumbs), splinting (115 children, 138 thumbs), and passive exercising (89 children, 108 thumbs). The mean follow-up periods were 59 (surgery), 23 (splinting), and 76 months (exercising), respectively. Full IP joint motion without residual triggering was achieved in 95% of all children undergoing surgery, in 67% of children treated with continuous splinting, and 55% after passive exercising. Based on the low level of evidence available, it seems that open surgery resulted in more reliable and rapid outcomes compared with nonoperative treatment.

OBJECTIVES: This paper describes the natural course of irritable hip pain associated with spinal rigidity and pain in the thoracic region with subsequent development of mild kyphosis in a girl with a mutation in the collagen 2 alpha 1 gene (type II collagenopathy). METHODS: Phenotypic and genotypic characterization was carried out in a 14-year-old girl to identify the underlying pathology of severe irritable hip pain associated with thoracic spinal rigidity and pain. Detailed clinical examination, skeletal survey and genetic testing were performed accordingly. Bernese periacetabular osteotomy was used to alleviate pain and to improve the anatomical correlation of the acetabular and femoral heads. RESULTS: Short stature associated with acetabulo-femoral dysplasia, spinal osteochondritis (Scheuermann's disease) and mild thoracic kyphosis were the most prominent abnormalities. Genetic analysis showed a heterozygous mutation in the collagen type II gene (COL2A1-c.1636G>A, p. G546S). A Bernese periacetabular osteotomy was performed to improve the clinical status of the patient. There was significant improvement in the extrusion index, the acetabular index and the lateral center-edge angle. CONCLUSIONS: Hip dysplasia and Scheuermann's osteochondritis have never been reported in connection with a mutation in COL2A1 (collagenopathy type II). Awareness is needed for careful phenotypic and genotypic characterization in patients with irritable hip pain and spinal stiffness.

Congenital dislocation of the knee (CDK) is a rare deformity presenting itself either as an isolated idiopathic entity or in the context of syndromes like arthrogryposis, myelodysplasia or Larsen syndrome. Patients can be diagnosed clinically after childbirth based on hyperextension of the knee. Confirmation of the diagnosis is done by X-ray or sonography. Many theories concerning the pathogenesis have been proposed since CDK was described; according to recent literature fibrosis and contracture of the m. quadriceps is the most likely reason. Therapy should start as soon as possible after birth, conservatively using redressing casts or operatively in syndromal conditions aiming for reduction. The prognosis concerning re-dislocation is benign; a good outcome was shown for idiopathic CDK.

PURPOSE OF THE STUDY: Congenital femoral deficiency (CFD) is a rare and complex deformity. The results and complications of surgical correction of this deformity using ring fixators (Ilizarov/Taylor Spatial Frame) have been evaluated. MATERIAL AND METHODS: We retrospectively reviewed a consecutive series of 30 patients with CFD, between the ages of 3.3 and 17 years (mean, 9.3 years), with 35 lengthening procedures. Ten cases were treated with an Ilizarov frame, 25 cases with a Taylor Spatial Frame (TSF). RESULTS: The average lengthening at femoral osteotomy was 44.3 mm. Nine patients underwent an additional tibial lengthening by an average of 24.2 mm. The total lengthening was 50.5 mm (28-85 mm). A fracture after removal of the fixator occurred in 25.7% of the cases, and a pin-site infection with the subsequent need of operative revision was found in 8.5%. A subluxation of the knee joint was observed in 11.4% and a persistent limitation of the knee joint range of motion in 22.8%. CONCLUSIONS: Despite several complications, the use of ring fixators, especially the TSF, is an effective method for treatment of this complex deformity. The complication rate was similar with the use of either ring fixator. Some complications can be decreased with experience. The risk of knee dislocation can be reduced by joint bridging and fractures after frame removal can be avoided by prophylactic rodding.

UNLABELLED: The knee has various pathologic appearances in patients with congenital longitudinal deformities of the lower extremities. Radiographs from 39 patients with unilateral longitudinal congenital deficiencies of the lower extremities were analyzed to describe epiphyseal and metaphyseal configurations and position of the epiphyseal plate. We defined 22 radiographic parameters of the femur and tibia, calculated the mean values, and compared the parameters of the affected knee with the unaffected knee for patients in different age groups. In the femur, we observed hypoplasia of the lateral condyle in width and height. In the tibia, the lateral condylar hypoplasia was manifest primarily by lateral horizontal deficiency. Age group comparisons showed no horizontal epiphyseal deficiencies in the older patients, but there was persistence of vertical epiphyseal deficiencies. Bony deformities in congenital longitudinal deficiencies mainly were attributable to dysplasia of the lateral epiphysis in the distal femur and proximal tibia, whereas positions of the epiphyseal plate had varying physiologic values. LEVEL OF EVIDENCE: Diagnostic study, Level II. See the Guidelines for Authors for a complete description of levels of evidence.

Congenital unilateral anterolateral tibial bowing in combination with a bifid ipsilateral great toe is a very rare deformity which resembles the anterolateral tibial bowing that occurs in association with congenital pseudarthrosis of the tibia. However, spontaneous resolution of the deformity without operative treatment and with a continuously straight fibula has been described in all previously reported cases. We report three additional cases and discuss the options for treatment. We suggest that this is a specific entity within the field of anterolateral bowing of the tibia and conclude that it has a much better prognosis than congenital pseudarthrosis of the tibia, although conservative treatment alone may not be sufficient.

Congenital pseudarthrosis of the tibia (CPT) is one of the most challenging conditions in paediatric orthopaedics. The history of CPT treatment is characterised by repeatedly ineffective surgical interventions with the inevitable outcome of severe disability. Most procedures failed to account for the complexity of the problem. The past two decades have witnessed more experience having been gained with the Ilizarov technique. This method provides a comprehensive approach to all aspects of CPT problem, allowing the surgeon to simultaneously address the problems of union as well as those of deformity, length discrepancy joint function, ankle valgus and weight bearing. It appears that the goal to achieve stable fusion before the child begins school is attainable. In the pre-pseudoarthrotic stage, bracing should be preferred to surgery until the patient is in an older age group. This study reports on the results of 19 patients: 15 have finished treatment, and 14 of them with a stable fusion at follow-up. The results were highly encouraging in reaching the ultimate goal of avoiding amputation and achieving a well-functioning limb.

We analyzed standardized scapulolateral and anteroposterior view radiographs in 147 patients with impingement syndrome to detect a subacromial osteophyte or spur, which should be of value in those patients who require surgical treatment. Standard anteroposterior view radiographs with a fixed tube angulation, 0 and 30 degrees, were compared to anteroposterior view radiographs with individual tube angulation (the radiograph beam was tilted caudally, depending on the slope of the acromion). In all patients, we identified an acromion bony overhang on the anteroposterior view radiographs with individual tube angulation having an average thickness of 5 mm, which correlated well with the intraoperative findings at arthroscopic acromioplasty. In only 35% of the patients did we detect a subacromial osteophyte or spur on radiographs with a fixed tube at 0 degrees angulation and in 92%, we found a false impression of a spur on the 30-degree views because of overexposure. We conclude that, anteroposterior view radiographs with an individual caudally-tilted X-ray beam, depending on the acromion slope, can show the whole spur and/ or size of the osteophyte, on the anterior margin of the acromion.

Congenital femoral deficiencies remain a surgical challenge. There is no common classification: both radiological and clinical methods are recommended. Depending on the severity of the deformity, reconstructive and lengthening techniques are performed, while accompanying deformations are taken into consideration. In addition, amputation or fusion techniques together with orthotic devices are used. A total of 35 patients (37 extremities) with congenital femoral deficiencies have been treated at the Orthopaedic Hospital Vienna-Speising, from 1982 to 1998. 24 extremities were treated with reconstructive and/or lengthening techniques. Results and complications are reported.

1291 newborn were examined sonographically between May 1986 and June 1987. Some of them were followed up radiologically until February 1989. The schedule of examination and treatment is given below. Neonatal examination suggested the immediate treatment of 3.25% of the newborn (1.97% of all hips), either Pavlik harness or abduction brace. The mean duration of therapy was 4.3 months. At the end of therapy type I was always in evidence. Patients with severe dysplasia (Graf type IIc or worse) were followed up radiologically at the end of the 2nd year of life. An avascular necrosis of the femoral head was not observed; in one case there was an acetabular index of 30 degrees; the remaining hip joints showed normal findings. We conclude that ultrasound examination in the neonatal period is a worthwhile procedure.
