A retrospective chart and radiograph review was conducted after identifying 44 patients with 61 hips who underwent varus derotational osteotomy with Rush rod fixation at our institution between 2006 and 2016. We identified 44 patients with 61 hips who underwent the procedure. Information from follow-up clinic visits was gathered and any complications were noted. The patients' radiographs were analyzed to measure neck-shaft angle, center-edge angle, and acetabular index. At the time of surgery, 44 patients (61 hips) also had soft tissue releases performed, 44 (61 hips) had an open reduction of the hip, and 39 (55 hips) had Dega acetabular osteotomies performed as well. The average pre-operative neck-shaft angle was measured at 163.0° (range 128-180) with average post-operative neck-shaft angles measuring 111.3° (range 85-167). The acetabular index improved from an average of 33.3° (range 16-60) to 16.4 (range 4-35). Post-operative Center-Edge Angle measured 29.7° (range 5-45). There were no infections or cases of avascular necrosis of the femoral head.

Duplex ultrasonography was performed on injured and uninjured arms, both preoperatively and postpinning, and interpreted by a board-certified pediatric radiologist. Degree of artery stenosis and peak systolic velocity (PSV) of arterial flow were recorded from the duplex.

YouTube has emerged as an important source of health-related information for patients and families. Parents seek information about clubfoot on YouTube. However, the quality of these videos remains unknown. Therefore, we decided to evaluate the quality of YouTube videos about clubfoot. We searched YouTube for clubfoot videos using appropriate keywords. English language videos with more than 10 000 views were included. Three fellowship trained pediatric orthopedic surgeons independently assessed the videos and classified them into corporate, hospital, education and private. The quality of information was assessed using the Modified DISCERN and JAMA benchmark scores. The search yielded 12 060 videos of which 42 were analyzed. There were 9 (21%) videos from corporate organizations, 12 (29%) from hospitals, 3 (7%) from educational organizations and 18 (43%) by private individuals. The mean Modified DISCERN score was 2.1 ± 1.07 (range 0.3–4) and mean JAMA benchmark score was 0.9 ± 0.65 (range 0–2).

While cross-cultural evidence supports parental presence during some pediatric procedures, no study addresses parental presence during fracture reductions. This study investigates parent experiences during their child’s reduction and provides guidance regarding parental attendance during fracture reductions. Sixty consecutive parents were retrospectively surveyed about their experience during their child’s fracture reduction. Parents were grouped according to presence or absence during the reduction and were compared. Forty parents attended the reduction and 20 parents were absent. All parents attending the reduction were satisfied with their experience. Thirty-nine parents (98%) believed their presence was helpful for their child and 36 (90%) believed it was personally helpful. Of the 20 absent parents, four (20%) were dissatisfied with their experience, five (25%) believed it was personally harmful, and two (10%) thought it was harmful to their child. All parents reporting negative experiences were prohibited from attending the reduction. When deciding about parental presence during reductions, 55 (92%) parents wanted to be included in this process. Overall, 47 parents (78%) wanted to attend the reduction and 52 (87%) would prefer to attend a future reduction. Most parents prefer to attend their child’s fracture reduction and believe their presence is helpful personally and for their child. Parents in attendance report a positive experience, while parents prohibited from attending report dissatisfaction with the experience and believe their absence is harmful to themselves and their children. It is recommended that healthcare workers consider parental attendance during pediatric reductions.","PeriodicalId":16709,"journal":{"name":"Journal of Pediatric Orthopaedics B","volume":"179 1","pages":"32 - 36"},"PeriodicalIF":0.0,"publicationDate":"2019-11-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85047341","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study included 26 feet in 18 patients, who underwent tibialis anterior tendon transfer as a part of management of their congenital clubfoot. The mean age was 3.6 years (ranging from 2.5 to 5 years), all patients were followed up for 6 to 30 months (mean = 14 months). The transferred tibialis anterior tendon was anchored in the third cuneiform using transfixing K wires. This novel technique resulted in successful and stable anchoring of the transferred tibialis anterior tendon. The transferred tendon was well palpated in all patients with active dorsiflexion, with no associated tendon rupture, anchoring problems, or wound complication. Our technique is secure, reliable, and economic with no special equipment needed. It could successfully avoid the plantar skin complications associated with pullout sutures and neurovascular injury.","PeriodicalId":16709,"journal":{"name":"Journal of Pediatric Orthopaedics B","volume":"44 1","pages":"379 - 381"},"PeriodicalIF":0.0,"publicationDate":"2019-11-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83672594","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although there is only a single study found on the interobserver variability and none found on the intraobserver variability, it is commonly used for prognostication and guiding management decisions. The aim of this study was to determine the reliability and reproducibility of the Langenskiöld classification. A retrospective review of radiographs was done of patients treated for infantile and juvenile Blount’s disease at Chris Hani Baragwanath Academic Hospital from 2006 to 2016. There were 70 radiographs of acceptable quality, which were reviewed and staged on two occasions according to the Langenskiöld classification by three orthopaedic consultants and three orthopaedic surgery senior residents. Pearson correlation coefficients, percentage agreements, and κ statistics were used to evaluate both the reliability and reproducibility. Of the 70 images staged, only two (2.9%) were staged the same by all six observers, and 20 (28.6%) images differed by a single stage. The consultants had 17 (24.3%) images staged the same whereas the residents had 12 (17.1%) images staged the same. The overall κ for all six observers showed a fair agreement of 0.24. Again, the consultants had a higher κ-value compared to residents of 0.25 and 0.24, respectively. The reproducibility amongst all observers was fair with a κ-value of 0.38. The consultants had a higher mean score of 0.48 compared to 0.26 for the residents. There was only a fair overall reliability and reproducibility amongst the six observers. We recommend the Langenskiöld classification be used with caution when being used for prognostication and management planning as well as when interpreting any research relying on this classification.

All pediatric medial epicondyle fractures treated with a single screw over a 7-year period were queried for this retrospective case-control study. Hardware removal was performed only if the patient experienced a complication or implant-related symptoms that were refractory to non-operative management. Of the 137 patients included in the study, a washer was utilized in 90 (66%). Thirty-one patients (23%) ultimately underwent hardware removal. There was not an increased need for implant removal in those with a washer (P = 0.11).

Overall, 107 (78%) patients regained full ROM at a mean of 13.9 ± 9.7 weeks after surgery with no significant difference along the lines of washer use. Use of a washer did not affect the need for subsequent implant removal or elbow ROM after fixation of medial epicondyle fractures, even in athletes.

The purpose of this study is to assess the efficacy of telehealth as a tool for the follow-up of children with nondisplaced elbow fractures. We hypothesize that patients treated via telehealth will have comparable clinical outcomes as those treated at our institution, with increased patient satisfaction. We conducted a randomized trial, which included 52 children with type I supracondylar humeral fractures, or occult elbow injuries, divided in two groups, based on the type of care provided during the fourth-week follow-up appointment: cast removal at our institution (group A) or cast removal at home via telehealth appointment (group B). The time duration and professional fees for this week 4 follow-up were calculated. Patients in both groups returned to our institution for a final follow-up in week 8. We measured the amount of fracture displacement, range of motion, pain, and patient satisfaction. There was no statistically significant difference in fracture displacement, range of motion, or pain scores between groups. The mean length of the fourth-week clinical encounter was higher in group A than group B (47.2 vs. 17.6 min, respectively; P < 0.001). Initially, the mean patient satisfaction scores were nearly identical in both groups (97%) until patients in group A were made aware of this difference in time duration, at which their mean satisfaction score decreased to 76.4% (P = 0.05). The use of telehealth as a tool in the treatment of nondisplaced pediatric elbow fractures is appealing.
