This study evaluated the static, postural, dynamic, and clinical outcomes among five groups of patients: a bilateral CTEV (congenital talipes equinovarus) group treated with tenotomy ( n = 14), bilateral CTEV group treated conservatively ( n = 6), unilateral CTEV group treated with tenotomy ( n = 7), unilateral CTEV group treated conservatively ( n = 3), and control group ( n = 20). Data were collected through baropodometric examinations and clinical evaluations using Pirani, clubfoot assessment protocol, foot and ankle disability index (FADI), and American Orthopedic Foot and Ankle Society scores. Bilateral CTEV patients treated with tenotomy showed no statistically significant differences compared to healthy controls. Significant differences were found in lateral-lateral variation in the bilateral postural group ( P  = 0.002) and in static peak pressure in unilateral tenotomy patients ( P  = 0.046). Dynamic comparisons revealed significant differences in mean pressure between unilateral groups ( P  = 0.002) and lateral-lateral variation in bilateral groups ( P  = 0.004). The Pirani score showed significant differences between tenotomy-treated and postural patients ( P  = 0.000). Statistically significant differences in FADI scores were found between bilateral groups ( P  = 0.0037), between tenotomy-treated groups ( P  = 0.0020), and between the bilateral tenotomy-treated group and the unilateral postural group ( P  = 0.021). Bilateral CTEV patients treated with tenotomy develop static and dynamic values comparable to healthy controls. Bilateral patients develop better dynamic values compared to patients with a unilateral variant. Level of evidence: III.

This study aimed to perform a systematic review and network meta-analysis (NMA) to examine which open approach is superior in terms of outcomes and complications in the treatment of pediatric supracondylar humerus fractures. MEDLINE/PubMed, Embase, Web of Science, Clinicaltrials.gov , and Cochrane Library were searched from database inception to December 2022 and screened for relevant studies. Data were collected regarding patient demographics, Flynn's functional and cosmetic outcomes, and complications. Unsatisfactory Flynn's and complications were considered negative events. Comparisons of outcomes from aggregate data from each surgical approach using relative risk (RR) with a 95% confidence interval (95% CI) were performed. The NMA of overall negative events was conducted using a Bayesian hierarchical random-effects model analysis. A total of 26 studies involving 1461 patients were included; 459 (31.4%) patients underwent a closed reduction and percutaneous pinning (CRPP), 84 (5.7%) an anterior approach, 240 (16.4%) a medial, 220 (15%) a lateral, and 458 (31.3%) a posterior. The lateral and posterior approaches demonstrate a higher risk of negative event in the NMA compared to CRPP [RR = 2 (1.03, 3.85); RR = 2.63 (1.96, 3.57), respectively], anterior approach [RR = 3.33 (1.11, 10); RR = 4.35 (1.49, 12.5), respectively], and medial approach [RR = 1.82 (1.16, 2.86); RR = 2.38 (1.23, 4.76), respectively]. The medial approach resulted in a similar negative event rate compared to the anterior [RR = 1.82 (0.58, 5.88)]. The anterior and medial open approaches yield superior functional and cosmetic outcomes with fewer complications compared to the lateral and posterior.

The objective of this study is to describe and evaluate dorsal hemiepiphysodesis of the first metatarsal as an osteotomy replacement technique. Retrospective analysis of patients with pes cavovarus (PCV) treated in our center with dorsal hemiepiphysodesis of the first metatarsal. Meary's angle, calcaneal pitch, and Moreau Costa Bartani were compared pre and post-operatively and the ratio between width and foot length was monitored. Between May 2012 and May 2022, eight patients (14 feet) with PCV underwent dorsal hemiepiphysiodesis of the first metatarsal combined with the Steindler procedure. Four patients (50%) were male. The average age for boys at surgery was 10.75 years (10-11) and for girls was 9.75 years (8-11). Most patients (87.5%) had idiopathic PCV and 12.5% had a neurological PCV. Median follow-up was 4.3 years (1.5-10) and a benefit was seen in all patients in Moreau Costa Bartani angle (112.64° vs. 120.59°; P value = 0.003), calcaneal pitch (26.48° vs. 25.36°; P value = 0.091) and Meary's angle (10.60° vs. 5.36°; P value = 0.008) after surgery. Supination improvement was also shown (0.21 vs. 0.24; P value = 0.039). Despite the limited number of patients, the results demonstrated that dorsal hemiepiphysiodesis of the first metatarsal can be a valid alternative to osteotomy of the base of the first metatarsal, with less morbidity and a gradual and dynamic correction throughout growth.

Pediatric humerus lateral condyle fractures (PHLCF) are one of the most common fractures among children. PHLCF is approximately 20% of all pediatric elbow fractures. Among the treatment modalities are: nonoperative treatment with splinting, closed reduction with percutaneous K-wire fixation (CRPP), and open reduction with K-wire fixation (ORIF). We aimed to evaluate radiological, functional, and clinical outcomes of Jakob type 2 PHLCF treated either with CRPP or ORIF. We hypothesized that CRPP may be as safe and effective as ORIF for Jakob type 2 PHLCF. In this retrospective study, we included patients with Jakob type 2 PHLCF operatively treated in a single center. Patients with multiple fractures or open fractures were excluded from the study. 69 patients between ages 2 and 12 were included and they were divided into two groups. Group 1 included the patients treated with CRPP, whereas Group 2 included the patients treated with ORIF. Demographical, radiological, clinical, and functional parameters were evaluated. Average duration of surgery ( P  < 0.001), initial displacement ( P  = 0.014), and duration of admission ( P  < 0.001) were significantly less in group 1. Group 2 had significantly higher percentage of left-sided injury than group 1 ( P  = 0.038). Average varus deformity score was significantly higher in group 1 ( P  = 0.014). CRPP was associated with shorter duration of surgery and hospital stay. Functional, clinical, and radiological outcomes were identified similar between CRPP and ORIF for Jakob type 2 PHLCF. CRPP may be as safe and effective as ORIF for Jakob type 2 PHLCF.

We have encountered consecutive children/adolescents with a volar Barton fracture (VBF) pattern without involving the physis. These were managed by buttress plating; thus, we would like to report the radiological and clinical outcomes through retrospective case series and suggest the revisiting of the 'VBF category' in this population. We screened children/adolescents with a diagnosis of trauma to the bony structures in the wrist from 2008 to 2019. Of these patients, 16 who met our inclusion/exclusion criteria were investigated. At the final follow-up performed at least 2 years postoperatively, radiologic and clinical outcomes were evaluated. The mean age at the time of injury was 12.88 years old. At the final follow-up, the volar tiltings, radial inclinations and ulnar variances were 10.13°, 20.88° and -0.50 mm, respectively. None of these radiologic parameters were significantly different from the contralateral values, except the radial inclination. The mean visual analog scale score was 0.38. The mean range of motion arcs were 136.56° and 157.81° in the flexion-extension and pronation-supination arcs, respectively, and the grip strength was 22.00 kg. The mean modified Mayo Wrist Score was 92.8. The radiologic and clinical outcomes compared with the contralateral side were not significantly different from those in a previous report. A VBF pattern without involving the physis in the child/adolescent population was treated satisfactorily by buttress plating. Thus, including the previously reported 'SH-II in sagittal plane' injuries, the current injury pattern would be better called a 'Barton equivalent' fracture. Level of Evidence: Level IV, retrospective case series.

The aim of this study was to compare early clinical and radiographic results of single- versus double-pin fixation of unstable pediatric distal radius fractures. A total of 103 consecutive closed distal radius fractures treated with either single or double percutaneous pinning at a tertiary level I pediatric hospital were analyzed. All patients had open physes and had fractures that failed initial closed reduction and casting. Postoperative fracture displacement was assessed by measuring the difference in angulation of the radius in the anteroposterior and lateral views from intraoperative fluoroscopic images to postoperative radiographs taken on the day of pin removal. Complications were identified from the medical record review. In 103 operative distal radius fractures in 101 patients (70 males, 31 females), 52 and 51 distal radius fractures were treated with single and double pinning, respectively. The median [interquartile range (IQR)] age at the time of surgery was 12.1 (9.0-14.0) years, with the single-pinning group being younger by 1.9 years ( P  < 0.01). Median (IQR) postoperative angulation in the anteroposterior radiograph (coronal plane) was 2° (1-7°) with one pin versus 1° (0-2°) with two pins ( P  < 0.01). Median (IQR) postoperative angulation in the lateral radiograph (sagittal plane) was 3° (1-10°) with one pin versus 1° (0-2°) with two pins ( P  < 0.01). There were no significant differences in complications between the single- and double-pinning groups. Double-pin fixation resulted in a statistically significant, but clinically negligible, reduction in postoperative fracture displacement compared with single-pin fixation. Complication rates were similar in both groups. These findings suggest that either single- or double-pinning techniques can be effective, provided appropriate reduction and postoperative immobilization are achieved.

Supracondylar fractures of the humerus represent the most common surgical fractures in pediatric patients. There is a discourse regarding the influence of the surgeon training on treatment. Different studies show equivocal effect of subspecialty training. We conducted a single center case control study to evaluate the outcomes of type 3 fractures (fully displaced) comparing pediatric-trained orthopedic surgeons (PTOS) and non-pediatric trained orthopedic surgeons (NTOS). In this retrospective study, we investigated the surgical outcomes of type 3 supracondylar fractures of the humerus in children treated between the years 2012 and 2019, divided by surgeon type. During the research, a policy reform at our department was established and PTOS became the only surgeons for those injuries starting from September 2017. Patients' demographics, perioperative details, and postoperative course were recorded. Primary outcome was reoperations, and secondary outcomes were open reductions, infections, length of surgery, and neurological deficits. 1175 patients were diagnosed with supracondylar fractures at our Level I trauma center, and 346 cases were diagnosed with radiologically confirmed type 3. Overall, 312 cases were analyzed; 113 cases were diagnosed before 1 September 2017 and treated by NTOS, and 199 cases were treated by PTOS until 31 December 2019; 7.1% (8) of the patients treated by NTOS had to be reoperated compared to 1.5% (3) of the patients treated by PTOS ( P  = 0.014). There was significant difference looking at postsurgical complications and surgery length. This study's findings suggest that PTOS achieve superior outcomes when treating patients with type 3 supracondylar humerus fractures. Level of evidence: Level III.

This study aimed to summarize the clinical characteristics of acute epiphyseal osteomyelitis and acute metaphyseal osteomyelitis of long bones in children. Data of 43 children with acute osteomyelitis of long bones diagnosed and treated from November 2017 to January 2021 were retrospectively analyzed. Medical records, laboratory results, and MRI were reviewed. Surgical drainage of lesions was done to retrieve infective fluid and tissue for examination. There were 12 cases of metaphyseal and epiphysis involvement, including five boys and seven girls, aged from 1 to 12 years old, and the length of hospitalization was 21-45 days. There were six cases of distal femur, five cases of proximal tibia, and one case of distal humerus. The pathogenic microorganisms were methicillin-sensitive Staphylococcus aureus (MSSA) in six cases and methicillin-resistant Staphylococcus aureus (MRSA) in six cases. No complications were reported during the follow-up. Thirty-one cases of simple metaphyseal involvement, including 20 boys and 11 girls, aged 19 days to 12 years, and the length of hospitalization was 18-60 days. Twelve cases of distal femur, 11 cases of proximal tibia, three cases of distal humerus, two cases of proximal tibiofibular, two cases of proximal fibula, and one case of proximal ulna. The pathogenic microorganism was MSSA in 26 cases and MRSA in five cases. One patient with knee contracture during follow-up. Epiphyseal osteomyelitis is rare but can occur in older children. The prognosis is good with aggressive surgical treatment.
