Kim KH, Jeon JY, Lee S, Bae K, Kang MS. Injury-mechanism directness as a key factor for fracture laterality in pediatric extremity fractures. J Orthop Sci 2023; 28:1379-1383. [PMID: 36456388 DOI: 10.1016/j.jos.2022.10.024] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/26/2022] [Revised: 09/08/2022] [Accepted: 10/03/2022] [Indexed: 11/29/2022]
Abstract
BACKGROUND Associations between certain extremity fracture sites and laterality in pediatric trauma are well known, whereas the rationale for such laterality tendencies are unclear. We hypothesized that the laterality tendency of a specific fracture would be affected by directness of injury mechanism and not by the fracture site itself. METHODS We retrospectively enrolled 1382 children (aged 2-16 years) who were diagnosed with extremity fractures sustained during loss-of-balance situations and investigated the laterality tendencies (dominant vs. non-dominant extremity) of specific fracture sites. Multivariate analyses were sequentially performed to adjust for potential confounding variables-with and without injury-mechanism directness as a covariate. RESULTS In the upper extremities, the non-dominant side was more prone to fractures (p < 0.001), especially of the distal supracondylar humerus, radial and/or ulnar shaft, and distal radius. In the lower extremities, the dominant side was more frequently fractured (p < 0.001), especially at the tibial shaft and distal tibia. However, the predisposing effects of specific fracture sites on fracture laterality were not statistically significant when in analysis adjusted for injury-mechanism directness as a covariate. Fracture laterality was affected by whether the injury mechanism was direct or indirect. Indirect injury to the upper extremity was strongly associated with non-dominant arm injury (odds ratio 0.686 [95% CI 0.517-0.991]; p = 0.009), whereas indirect injury to the lower extremity was strongly associated with dominant leg injury (odds ratio 2.138 [95% CI 1.444-3.165]; p < 0.001). CONCLUSIONS Injury-mechanism directness, rather than fracture site itself, is a key factor that affects fracture laterality in pediatric extremity fractures. These findings are helpful for improving our understanding of which factors may affect fracture laterality among children.

Abstract
Musculoskeletal injuries of the lower limb are frequent in pediatric patients and represent the most common cause of emergency department admissions. Acute sports-related injuries commonly involve the lower extremity, as the knee and ankle are the most frequently injured parts. Physeal fractures are common injuries in children and adolescents participating in contact sports, which may lead to growth disturbances and cause limb length discrepancy. It is imperative for pediatric trauma centers to implement evidence-based multispecialty protocols for the perimanagement of the injured child, especially through the postdischarge and rehabilitation phases, in order for the child to resume active daily living.

Abstract
BACKGROUND Plate fixation has been the traditional technique for fracture repair of unstable ankle injuries with an associated lateral malleolus fracture. Recently, biomechanical and clinical data have demonstrated lag screw only fixation to be an effective alternative to plate fixation in the adult population. This comparison has yet to be studied in the adolescent or pediatric population. The objective of this study was to compare lag screw only fixation with traditional plating for lateral malleolus fractures in adolescents. METHODS A retrospective review was conducted of 83 adolescents with unstable oblique lateral malleolus fractures treated at a single pediatric level-1 trauma center between 2011 and 2019 with a minimum clinical follow-up until fracture union. Patients were divided into 2 surgical groups: (1) plate fixation (n=51) or (2) lag screw fixation (n=32). Radiographic and clinical outcomes and complications were measured in both groups. RESULTS All patients in both groups achieved our primary outcome measure of fracture union without loss of reduction. The mean surgical time for subjects treated with a plate was 15 minutes longer (64 vs. 49 min) (P=0.001) and these patients were 3.8 times more likely to have symptomatic implants (P<0.044) than subjects treated with screws. Approximately 50% of the cohort was available by phone for patient-reported outcomes at a mean follow-up of 50 months. The mean Single Assessment Numerical Evaluation scores, Foot and Ankle Ability Measure Activities of Daily Living scores, Foot and Ankle Ability Measure sports scores, and return to sports rates were similar (92 vs. 93, 98.2 vs. 98.1, 93.2 vs. 94.0, 95% vs. 86%, respectively; P>0.05) between the 2 treatment methods. CONCLUSIONS Lag screw only fixation is a safe and effective procedure for noncomminuted, oblique fibula fractures in the adolescent population as demonstrated by equivalent fracture healing rates without loss of reduction and similar outcome scores. Given these comparable results with the additional benefits of shorter surgical time and less symptomatic implants, lag screw only fixation should be considered as a viable treatment alternative to traditional lateral plating in the adolescent population.

Abstract
Computed tomography is useful for preoperative planning and postreduction assessment for intra-articular pediatric ankle fractures. Nondisplaced pediatric ankle fractures can be effectively managed with cast immobilization and close radiographic follow-up evaluation. Physeal ankle injuries in younger children with considerable growth remaining should be followed closely for at least one year after injury as growth arrest may result in substantial angular deformity. Open reduction and internal fixation should be strongly considered when an articular step-off of <2 mm cannot be maintained by closed means for Salter-Harris type-III and IV and transitional ankle fractures.

Abstract
The pediatric triplane ankle fracture represents a unique spectrum of injury that does not fit neatly into the Salter-Harris classification of physeal injury. This fracture is particular to the pediatric population and often is termed a transitional injury. It is the result of the characteristic asymmetric closure of the distal tibial physis over a period of approximately 18 months. The triplane ankle fracture is a multiplanar injury with three classically described fracture fragments. It has several variations and represents 5% to 10% of pediatric intra-articular ankle injuries. The fracture typically presents in children aged 12 to 15 years; incidence is slightly higher in boys than in girls. Nondisplaced triplane fractures and extra-articular fractures can be managed with immobilization in a long leg cast. Displaced fractures are treated with open reduction and internal fixation performed through an anterolateral approach or an anteromedial approach. Intra-articular reduction to within 2 mm is required for optimal treatment of these unique pediatric ankle fractures.

Abstract
INTRODUCTION The distal tibial physis is the second most commonly injured physis in long bones. Recent reports demonstrate a high rate of premature physeal closure (PPC) in Salter-Harris (SH) type I or II fractures of the distal tibia. METHODS At our institution, 137 distal tibial SH type I or II fractures were treated from 1994 to 2002. Reviews were performed on all patients and 91 fractures met inclusion criteria. Patients were categorized according to treatment. RESULTS We report a PPC rate of 39.6% in SH type I or II fractures of the distal tibial physis. We found a difference in PPC based on injury mechanism. The rate of PPC in patients with a supination-external-rotation-type injury was 35%, whereas patients with pronation-abduction-type injuries developed PPC in 54% of cases. Type of treatment may prevent PPC in some fractures. The most important determinant of PPC is the fracture displacement following reduction. DISCUSSION AND CONCLUSION PPC is a common problem following SH type I or II fractures of the distal tibia. Operative treatment may decrease the frequency of PPC in some fractures. Regardless of treatment method, we recommend anatomic reduction to decrease the risk of PPC.

Abstract
Musculoskeletal injuries in the pediatric population are unique and require a thorough evaluation by a trained specialist. Unlike adults, many of the injuries may be treated closed due to the amazing growth and remodeling potential of children. Special consideration should be taken in treating certain fracture patterns to prevent the long-term consequences of growth deformities and protect children from child abuse. It is the goal of this article to outline common orthopedic injuries in the pediatric population to facilitate proper care in the multidisciplinary evaluation and treatment of children.

Abstract
OBJECTIVE The Ottawa Ankle Rules (OAR) are criteria for predicting ankle fractures in adults allowing for insignificant fractures, defined as small avulsion fractures. Because the clinical significance of avulsion fractures and Salter-Harris type I fractures in children is unclear, we sought to prospectively evaluate the use of the OAR in children and to determine whether different criteria should be used for predicting ankle fractures in children. METHODS In this prospective study, patients younger than 18 years presenting to a pediatric emergency department (ED) with an acute nonpenetrating ankle injury were eligible for study participation. Information on 22 clinical variables was recorded on a standardized data sheet. The OAR were included but not specifically identified on the data sheets. A standard ankle radiographic series was obtained on all subjects. All fractures were considered to be significant. Follow-up phone calls were performed to assess final diagnosis and outcome. Sensitivity and specificity of OAR and other potential criteria for predicting ankle fractures in children were calculated. RESULTS A total of 195 patients with ankle injuries were evaluated. The mean age of patients was 12.6 years. Forty fractures (21%) were identified. The sensitivity of OAR was 83% (95% CI, 65-94%), specificity was 50% (95% CI, 41-59%), positive predictive value was 28%, and negative predictive value was 93%. Three independent factors were significantly associated with ankle fractures: inability to walk immediately after the event, inability to bear weight for four steps in the ED, and tender deltoid ligament. If one or more of these factors were present, sensitivity for predicting ankle fractures was 93% (95% CI, 78-99%), specificity was 27% (95% CI, 20-36%), positive predictive value was 23%, and negative predictive value was 95%. CONCLUSION The OAR cannot be applied to children with the same sensitivity as adults.

Abstract
Among 40 acutely injured ankles in children, surgery revealed a cartilaginous and/or bony fragment in 19, and an isolated rupture of the anterior talo-fibular ligament without any lesion of the bone or cartilage in another 17. In four ankles there was no ligament lesion. The lesions were surgically repaired. All ankles healed well and were painless and functionally stable at follow-up. In four ankles radiographs showed a small subfibular fragment, in which bony fusion had failed, but even these ankles were stable. Two other ankles gave a slightly positive sign in the clinical anterior drawer test as compared with the contralateral uninjured ankle, but there were no signs of functional instability nor were there any subjective complaints. Our results suggest that severe ankle sprains in children may cause isolated ruptures of the anterior talofibular ligament and frequently osteochondral lesions. We therefore advocate primary suture of ruptured lateral ligaments of the ankle in children.

Abstract
In an investigation of childhood and adolescence fractures (age groups 0-16) occurring in Malmö during 1950, 1955, 1960, 1965, 1970 and 1975-79, a total of 8682 were found. Four per cent or 373 ankle fractures were classified according to their roentgenological appearance. Avulsion fractures of the tip of the lateral malleolus were the most frequent, followed by fractures involving the distal fibular physis. Triplane and Tillaux fractures were the third and fourth most common fracture groups. Tillaux fractures were more common in girls (0.01 greater than P greater than 0.001). There was no statistically significant difference between the sexes in the other fracture groups or in the whole series. Most injuries were caused by low energy trauma. A foot caught in a bicycle wheel resulted more often in an epiphyseal fracture of the lateral malleolus than any other type of fracture. Otherwise no other etiological factor caused a significant number of cases in any fracture group. There was a seasonal variation with twice as many fractures during April and September as compared with July and December. The incidence showed a steady increase during growth which ceased after the early teens due to a lower incidence among girls in the age groups 15-16. The incidence increased significantly during the 30 years covered by this study.

Abstract
In 42 patients with idiopathic chondromalacia patellae, the effect of anterior displacement of the tibial tuberosity was evaluated in a prospective and randomized study. The operation performed was a modified Bandi procedure, and it resulted in significant relief of the patellofemoral pains, compared with the effect of a standard shaving procedure. Shaving alone was done in 22 patients of whom 6 (27 per cent) were classified as good, a result which may have been due to the placebo effect. In another 20 patients shaving was combined with anterior displacement of the tibial tuberosity resulting in pain relief in 18 (9 degrees per cent). The lack of unambiguously good results may be due to the fact that, although an anterior displacement reduces the retropatellar pressure, it cannot by itself compensate for an abnormal, dynamic tracking pattern of the patella.
