TL;DR: In this paper , the utility of lower extremity growth modulation with hemiepiphysiodesis in children with achondroplasia for correction of coronal plane deformities about the knee was evaluated.
Abstract: Background: Achondroplasia is the most prevalent form of skeletal dysplasia, affecting more than 250,000 individuals. Lower extremity angular deformities, particularly genu varum, are common in children with achondroplasia, often resulting in pain and limitation of function. The authors aim to determine the utility of lower extremity growth modulation with hemiepiphysiodesis in children with achondroplasia for correction of coronal plane deformities about the knee. Methods: The authors performed a retrospective chart review of a single center from 1/1/2000 to 12/31/2020 to identify pediatric patients with achondroplasia treated with hemiepiphysiodesis as their initial procedure at the distal femur and/or proximal tibia. Patients with adequate records and who had completed their treatment were included. Data collected included duration of treatment, complications, need for osteotomy, and radiographic measurements including initial and final mechanical axis deviation, knee mechanical axis zone, mechanical lateral distal femoral angle and medial proximal tibia angle. Results: Ten patients with 17 limbs met our criteria. Nine patients (15 limbs) were treated for genu varum and 1 patient (2 limbs) was treated for genu valgum. Prior to treatment, the mechanical axis fell in zone 3 in 59% of limbs and zone 2 in 41%. Average correction in mechanical axis deviation was 26.1 mm. Average change in mechanical lateral distal femoral angle was 10.3 degrees per limb, and average change in medial proximal tibia angle was 7.1 degrees per limb. Average treatment duration was 909 days. At final follow up, 81% (14/17) of limbs had the mechanical axis in zone 1, with the remaining 18% (3/17) in zone 2. No patient / limb underwent subsequent distal femur or proximal tibia osteotomy for coronal plane alignment. Conclusions: Children with achondroplasia can successfully be treated with hemiepiphysiodesis to correct coronal plane deformities at the distal femur and proximal tibia. Using this technique, no patient in our series required an osteotomy for genu varum/valgum. Level of Evidence: Therapeutic level IV, Case series.
TL;DR: In this article , the authors evaluated the safety and feasibility of over-expansion of right ventricle to pulmonary artery conduits during transcatheter pulmonary valve placement, and concluded that overexpansion can be performed successfully.
Abstract: Abstract Objectives: To determine the safety and feasibility of over-expansion of right ventricle to pulmonary artery conduits during transcatheter pulmonary valve placement. Background: Transcatheter pulmonary valve placement is an alternative to surgical pulmonary valve replacement. Traditionally, it was thought to be unsafe to expand a conduit to >110% of its original size. Methods: This retrospective cohort study from two centers includes patients with right ventricle to pulmonary artery conduits with attempted transcatheter pulmonary valve placement from 2010 to 2017. Demographic, procedural, echocardiographic and follow-up data, and complications were evaluated in control and overdilation (to >110% original conduit size) groups. Results: One hundred and seventy-two patients (51 overdilation and 121 control) had attempted transcatheter pulmonary valve placement (98% successful). The overdilation group was younger (11.2 versus 16.7 years, p < 0.001) with smaller conduits (15 versus 22 mm, p < 0.001); however, the final valve size was not significantly different (19.7 versus 20.2 mm, p = 0.2). Baseline peak echocardiographic gradient was no different (51.8 versus 55.6 mmHg, p = 0.3). Procedural complications were more frequent in overdilation (18%) than control (7%) groups (most successfully addressed during the procedure). One patient from each group required urgent surgical intervention, with no procedural mortality. Follow-up echocardiographic peak gradients were similar (24.1 versus 26 mmHg, p = 0.5). Conclusions: Over-expansion of right ventricle to pulmonary artery conduits during transcatheter pulmonary valve placement can be performed successfully. Procedural complications are more frequent with conduit overdilation, but there was no difference in the rate of life-threatening complications. There was no difference in valve function at most recent follow-up, and no difference in rate of reintervention. The long-term outcomes of transcatheter pulmonary valve placement with conduit over-expansion requires further study.
TL;DR: In this article , a study aimed to limit the number of in-office visits by conducting this last motion check by telehealth. But, the telehealth visits were not as effective as the in-person visits.
Abstract: Supracondylar humerus fractures are a common pediatric orthopedic injury requiring surgery. These patients are typically seen 4 weeks post-op for cast and pin removal followed by an 8–12-week post-op motion check. Our study aimed to limit the number of in-office visits by conducting this last motion check by telehealth. This was a single-surgeon series of consecutive surgically treated supracondylar humerus fractures. The primary outcome was the number of patients who completed their range of motion check remotely. Loss to follow-up at the telehealth visit was compared to a prior cohort for whom the range of motion visit was performed in person. Secondary outcomes included number of patients missing work/school for the in-person vs. telehealth visits and satisfaction with the in-person and telehealth visits. Twenty-two patients were enrolled during the study period. Sixteen (73%) successfully completed their telehealth follow-up, which was similar to the prior in-person cohort. Significantly more parents/children had to take a day off from work/school to attend the in-person visit. No patient required a subsequent in-person visit or referral to physical therapy. A total of 100% of patients reported excellent satisfaction with their telehealth visit. Overall satisfaction was similar comparing the in-person vs. telehealth visits (84% vs. 100% reporting excellent satisfaction, P = 0.12). Telehealth is a viable option for the postoperative care of surgically treated supracondylar humerus fractures. This approach limits in-office visits and decreases the need for parents/children to miss work/school while maintaining excellent satisfaction scores.
