RESUMO
Introduction: The treatment of late-presenting Perthes disease with extrusion is controversial and debatable. One of the options available is the labral shelf acetabuloplasty (LSA). Aim: The aim of the study was to evaluate the results of LSA in late-presenting Perthes disease in terms of clinic-radiological outcome measures. Materials and Methods: A retrospective analysis of prospectively collected data of patients with late presenting Perthes disease (Elizabethtown stage 2B onwards) treated by LSA by 2 experienced paediatric orthopaedic surgeons was performed. Data was collected of clinical parameters such as hip range of motion(ROM) and Harris Hip score and radiological parameters such as acetabular height, width and volume, shelf width, Centre Edge angle(CEA) and the lateral extrusion. Results: Thirty-five patients (28 males and 7 females) treated between 2012 to 2019 were analyzed. Majority were in Elizabethtown stage 3A (23) followed by 2B and 3B (12 each). At a mean follow up of 36 months, the hip ROM and the Harris Hip Score (from 65 ± 3.5 to 81.33 ± 7.12) improved significantly and there was a statistically significant improvement in terms of all radiological parameters. Majority of the hips were in Stulberg grade 3 (20) followed by grade 1 and 2 (7 each) and Stulberg 4 (1). There were no major complications in any of the patients of the series. Conclusion: Labral support shelf acetabuloplasty is a valuable surgery for late presenting Perthes disease and helps in maintenance of good coverage and allows restoration of range of motion over time.
RESUMO
CASE: A full-term neonate presented with right lower extremity ischemia at birth because of spontaneous thrombosis of the right common iliac artery. He was initially managed with supportive treatment, anticoagulation, and dressings; however, advanced gangrenous changes precluded salvage of the ischemic limb. A guillotine amputation was performed at day 15 of life, and the stump went on to heal well by secondary intention. CONCLUSION: Thromboembolic events occurring in infancy are well-recognized phenomena; however, it is far rarer to encounter a neonate born with "congenital gangrene". We discuss the etiology, approach to diagnosis, and treatment of this rare but devastating condition.

The Masquelet Induced Membrane Technique (IMT) is one of the tools in the surgeon's armamentarium for the management of segmental bone defects. The first stage of the IMT includes the insertion of a cement spacer, which is typically fashioned by the free-hand technique. We propose a novel technique for preparation of the cement spacer using a split syringe barrel as a mould. This technique produces a uniformly cylindrical spacer with minimum cement spillage, while also minimizing thermal damage to the surrounding soft tissues. It is a simple and cost-effective method that can be adapted for use in any long bone in children.
RESUMO
Closed reduction, arthrography and hip spica application is the treatment of choice for DDH between 6 and 18 months. There is a lot of controversy about what exactly constitutes an "acceptable" closed reduction and arthrogram and the arthrography findings are often difficult to interpret. In this video, the authors describe the technique to perform the arthrogram as well as the interpretation of the same. Various static parameters such as the femoral head coverage, the medial dye pool and the hourglass constriction are shown. In addition, the validity of the safe zone is discussed. With this video technique article, the authors hope that it becomes easy for the budding paediatric orthopaedic surgeon to perform and interpret the DDH arthrogram with ease.

RESUMO
The chondral shear fracture is a rare sub-type of pediatric capitellum fractures, in which the fractured fragment is almost entirely cartilaginous. Since the fractured fragment is not visible on plain radiographs, these injuries are often missed on initial presentation resulting in delayed diagnosis and poor outcomes. To our knowledge, only eight such cases have been reported in the past. We report the cases of two adolescents with chondral shear fractures of the capitellum, that were initially missed. They both presented to us several months following trauma, with pain and restricted elbow range of motion. They were treated by excision of the intra-articular loose fragment, and one child also required radial head excision due to advanced radio-capitellar arthritis. Both had good outcomes at 1 year follow-up. We provide a review of literature on this injury and emphasize the need for having a high index of suspicion when dealing with elbow trauma in adolescents, so as to avoid missing this rare, but distinct fracture pattern.
RESUMO
To study the bone age delay patterns in different stages of Perthes disease, 140 hand and corresponding hip radiographs in 83 patients were assessed. In the hand radiographs, the radius, ulna, metacarpals and phalanges (RUS) and carpal bone ages were calculated using the Tanner and Whitehouse 3 method and the Greulich and Pyle (G and P) bone age was assessed using the G and P atlas. From corresponding hip radiographs, the modified Elizabethtown stage was assessed. The RUS and carpal bone age as well as G and P bone age were found to lag behind the chronological age. The 95% confidence interval for the difference between RUS and G and P bone ages was 0.19 to 0.43 years and between carpal and G and P bone ages was -0.516 to -0.14 years, indicating a close agreement between the Tanner and Whitehouse 3 and G and P methods. The RUS bone age delay was maximum in stage Ia (2.00 +/- 1.08 years), whereas carpal delay was maximum in stage IIa (2.15 +/- 1.28 years). Bone maturation acceleration was observed in later stages of the disease as bone age tried to catch up with chronological age. Carpal delay was significantly greater than RUS delay from stage Ib to IIIb (P<0.05), but no significant difference was observed between carpal and RUS delays in stage IV (P=0.21), implying that bone maturation acceleration occurs in the RUS in the earlier stages, and carpal bone age tends to catch up with RUS bone age in the healed stage of the disease. The RUS and carpal bone age delays in stage I were significantly greater in severe (Catterall groups 3 and 4) disease than in mild (Catterall groups 1 and 2) disease. All patients in whom RUS or carpal bone age delay in stage I was greater than 2 years subsequently developed severe disease, indicating a positive correlation between bone age delay in stage I and subsequent extent of involvement of capital femoral epiphysis.

This study was undertaken to evaluate the accuracy of the Torg ratio for predicting the spinal canal stenosis in achondroplasia, by trying to establish its correlation with the corresponding effective sagittal canal diameter (ESCD) and dural sac ratio (DSR) on the MRI of the cervical spine. Lateral radiographs and the sagittal and axial MRI study of the cervical spine from C3 to C7 level were carried out in 18 asymptomatic achondroplasia subjects. A total of 90 levels were evaluated on the lateral radiographs and on the mid sagittal T2 MR images. On statistic analysis, the highest correlation coefficient for the Torg ratio compared with the ESCD was 0.74 at C6 level and the least was 0.45 at the C5 level. The highest correlation coefficient between the Torg ratio and the DSR was 0.79 at C3 level and the least was 0.42 at the C5 level. The highest coefficient of determination for the ESCD was 54% at C6 which translates into a poor correlation. The highest coefficient of determination for the DSR was 62 at C3 level, indicating a variable correlation. These results clearly show that the Torg ratio is of limited value in the assessment of the true sagittal spinal canal diameter in achondroplasia and its reliability as an indicator of severe cervical canal stenosis is questionable.

The goal of this study was to determine whether the available studies provide enough evidence that, in a borderline case of adolescent idiopathic scoliosis with a large (35 to 50 degrees) curve in a skeletally immature patient (Risser 0 to 2) with significant growth potential left, a conservative line of management in the form of bracing can be considered, rather than to rush into a potentially unnecessary major spinal surgery. We reviewed the literature spanning the last 20 years for the results of bracing in this specific group of patients. From the 9 studies selected, a group-specific data extraction was carried out. Three hundred and five patients with a 36 to 50 degrees scoliosis curve and Risser stages 0 to 2 were treated by bracing and the treatment was termed successful in 160 patients. Thus, more than half (52.5%) of the patients were successfully managed with a brace and were spared surgery. The current trend for management of these curves is early surgical intervention, the rationale being the ineffectiveness of bracing in preventing the progression of such a large curve and the difficulty in obtaining satisfactory correction by postponing surgery to a later date. On the basis of our results, we propose a conservative line of management for these curves, in contrast with current views, rather than to rush into a major spine surgery, expecting a favorable outcome with a well-supervised bracing program. If the curve progresses, surgery can always be considered later, keeping in mind the excellent correction obtained with the pedicle screw systems even for large curves of 70 to 100 degrees.

The results and complications of bifocal tibial osteotomies with gradual correction and lengthening by Ilizarov ring fixator performed in 47 tibiae in 24 achondroplastic patients were analyzed. Comparison was made between the parameters of angular and torsional deformities of the tibia preoperatively, at fixator removal, and at last follow-up. Of these parameters, statistically significant change was seen postoperatively in the values of medial proximal tibial angle, lateral distal tibial angle, mechanical axis deviation, and tibial torsion, which changed from 78.8 +/- 7.05 degrees, 103.2 +/- 11.8 degrees, 25.1 +/- 14.6 mm (medial), and 22.7 +/- 10 degrees (internal) preoperatively to 87.3 +/- 6.3 degrees, 90.9 +/- 5.4 degrees, 5.3 +/- 10 cm (medial), and 15.8 +/- 4.2 degrees (external), respectively, at the time of fixator removal; and this correction was maintained during the follow-up period. Mean total tibial lengthening was 6.84 +/- 1.3 cm. Average healing index was 26.06 days/cm. Complications observed were 15 pin tract infections, 1 residual varus, 1 overcorrection into valgus, 2 recurrence of varus, 22 equinus contractures, 2 premature consolidations, and 3 fibula malalignments. Recurrence of varus was observed in limbs with a residual abnormal medial mechanical axis deviation due to femoral deformity. A hundred percent incidence of equinus was observed in limbs with tibial lengthening of more than 40%, with distal tibial lengthening of more than 15%. To minimize the risk for occurrence of equinus, we recommend restriction of distal tibial lengthening in achondroplasia to less than 15%, although total tibial lengthening may exceed 40%. Fibula malalignment was not observed after double fibula osteotomy. This procedure is safe and efficacious if performed with strict adherence to prescribed technique.
