Prophylactic pinning for slipped capital femoral epiphysis: does it affect proximal femoral morphology?
This study was designed to determine whether prophylactic pinning of the unaffected hip in unilateral slipped capital femoral epiphysis affects the proximal femoral morphology. Twenty-four hips prophylactically pinned were compared with 26 cases observed. The articulotrochanteric distance (ATD) and the trochanteric–trochanteric distance (TTD) were measured. Postoperative radiographs were compared with final follow-up radiographs. The final TTD : ATD ratio was higher (P=0.048) in the pinned group, suggesting relative coxa vara/breva. There was a smaller difference between the two hips in the prophylactically pinned group (0.7) as opposed to those observed (1.47). Prophylactic pinning does not cause growth to stop immediately but alters the proximal femoral morphology.

The objective of this paper is to provide useful definitions for understanding the methods used and their possibilities, and report current and future developments for thoracic imaging. Prospective validation of AI tools will be required before reaching routine clinical implementation.
Background: Recent studies indicate that formal postreduction radiographs may be unnecessary for closed, isolated pediatric wrist, and forearm when mini C-arm fluoroscopy is used for reduction. Our institution changed the Emergency Department (ED) management protocol to reflect this by allowing orthopaedic providers to determine if fluoroscopy was acceptable to assess fracture reduction. We hypothesized that using fluoroscopy as definitive postreduction imaging would decrease total encounter time, without an increase in the rate of rereduction or surgery. Methods: Patients with closed, isolated distal radius/distal ul...
We describe our experience using transphyseal screws to correct deformity in this patient population. Methods: A retrospective chart and radiograph review was conducted on all juvenile and adolescent tibia vara patients who underwent lateral proximal tibial hemiepiphyseodesis using a single transphyseal screw. Charts were queried for preoperative and postoperative mechanical axis deviation, medial proximal tibial angle, lateral distal femoral angle, and postoperative complications or need for further surgery. Results: In total, 14 affected limbs in 9 patients (6 males) who underwent lateral proximal tibial transphyse...
Conclusions: There are 4 major undulations of the distal tibial physis. Kump’s bump is the largest. A centrally placed epiphyseal screw in the medial/lateral direction or screws from anterolateral to posteromedial and anteromedial to posterolateral would tend to avoid both valleys. Particular caution should be taken when placing metaphyseal screws in the anteromedial or posterolateral distal tibia. Physeal undulations were more difficult to visualize on the lateral view. Clinical Relevance: This study provides quantitative data on the topography of the distal tibial physis to aid hardware placement. Lateral view...
Conclusion: On the basis of our midterm to long-term postoperative outcomes, we believe that our method of surgical reconstruction provides a new option for the treatment of lateral polydactyly of the foot with mosaic-like alignment of the phalanx bones. Level of Evidence: Level IV—therapeutic studies.
Conclusions: This is the first study that follows AIS patients treated with spine stapling to skeletal maturity. Staples likely changed natural history in some of our patients. Initial percentage of correction on first standing postoperative PA x-rays was the only predictor of success. Stapling was safe without any long-term complications. Level of Evidence: Level III—retrospective study.
Conclusions: Three-dimensional reconstruction of the rib cage using biplanar stereoradiography is a reliable method to estimate preoperative thoracic parameters in patients with AIS. Level of Evidence: Level IV—diagnostic study.
Conclusions: Our goals for NF-1 scoliosis are to obtain deformity correction, to achieve stable instrumentation by using longer fusion levels and to attain a solid fusion mass that can tolerate continual erosion during the long-term follow-up. We achieve this by using a circumferential approach for EOS associated with NF-1. Level of Evidence: Level IV—case series.
Conclusions: In a large group of children treated for idiopathic EOS, we found a high prevalence of commonly associated conditions—hip dysplasia, torticollis, plagiocephaly, metatarsus adductus, and clubfoot. In 6.2% of our sample, a diagnosis of hip dysplasia was not made in a timely manner despite routine radiographic spine follow-up. With increasing subspecialization within pediatric orthopaedics, surgeons need to maintain vigilance in assessing the entire child. Level of Evidence: Level IV.
