RESUMO
Metacarpal fractures are common injuries in pediatric patients. In adults, cannulated intramedullary screws are an excellent stabilization option for metacarpal fractures and are widely used, but in pediatric patients with open physes, their use is a relative contraindication. The risk of injury to the physis in classic retrograde screw placement makes this type of osteosynthesis not an option. We present the case of an 8-year-old patient with fractures of two adjacent metacarpals with rotational malalignment and scissoring, in which closed reduction was performed, and stabilization with cannulated intramedullary screws using antegrade placement to avoid injury to the physis.
RESUMO
Purpose: Our purpose was to assess how nonunion of the metacarpals has been defined in prior investigations with respect to both clinical and radiographic criteria. We hypothesized that the definitions of nonunion would be highly variable. Methods: A systematic review was conducted using MEDLINE and Embase databases for clinical articles related to the treatment of metacarpal fractures (surgical and nonsurgical) from 2010 to 2021. Included articles were searched to assess how nonunion was defined based on clinical and radiographic criteria. We assessed the treatment type, method of union assessment, time to union, and incidence of union as well as article factors such as the following: date of publication, level of evidence, and publishing journal. Results: A total of 641 articles were identified, of which 102 were included for a definition of nonunion and 97 were included for the assessment of clinical management and outcomes. Of the included articles, 62% contained level IV evidence. A definition of nonunion was provided in 47% of the articles. Radiographic criteria alone, clinical criteria alone, or a combination of the 2 was used in 22%, 6%, and 19% of the cases, respectively, to define nonunion. The most common definition of nonunion was presence of fracture-site tenderness (with no time defined) in 20 articles (20%), followed by lack of radiographic healing at 6 months (15%). In the 97 included articles, the total number of fracture cases was 4,435 and nonunion was reported in 0.45%. Cases with nonunion were reported in a total of six articles that used a variety of treatment modalities. Conclusions: The definition of metacarpal nonunion remains highly variable and lacks standardization with respect to clinical and radiographic criteria. Clinical relevance: Standardizing the definition of nonunion for metacarpal fractures would allow for more accurate assessments of the incidence of this complication and may aid in improving diagnostic and management strategies.
RESUMO
PURPOSE: To describe management trends of fifth metacarpal neck (5MCN) fractures within a large health care system. We aimed to define patient and surgeon factors associated with nonsurgical versus surgical treatment, as well as to identify factors associated with receiving care only in the emergency department (ED). METHODS: We identified all 5MCN fractures within our system for the years 2012-2020 and recorded baseline demographics for cases. Injury, treatment, and fracture characteristics were all recorded. For fractures treated nonsurgically, we determined the type of immobilization used (if any) and recorded whether patients were seen only in the ED or received subsequent outpatient follow-up. Demographic comparisons were made between groups, and adjusted logistic regression models were generated to predict the odds of having a surgical 5MCN fracture or being seen in the ED only. RESULTS: There were 611 5MCN fractures over an 8-year period, of which 10% were treated surgically. During the first half of the study period, 8% of isolated cases were treated surgically compared with 7% of cases in the second half. Soft dressings were increasingly used. There were no nonsurgically managed cases that underwent subsequent surgical procedures for symptomatic nonunion or malunion. Twenty-one percent of patients were seen only in the ED. Fracture angulation, associated injuries, insurance status, and treatment by a hand surgeon were all significantly associated with an increased likelihood of surgery. CONCLUSIONS: Of the 611 5MCN fractures identified, 90% were treated nonsurgically. Patient and surgeon factors were associated with increased odds of surgery. Of patients who sought care for 5MCN injuries, >20% received no follow-up care outside of the ED. These data can be used to assess future changes in management trends and suggest that nonunion and symptomatic malunions are uncommon occurrences. TYPE OF STUDY/LEVEL OF EVIDENCE: Prognostic IV.
