Background: The aim of this study is to compare clinical and radiographic outcomes of open reduction and internal fixation versus closed reduction and percutaneous pinning of metacarpal fractures in relation to anatomic and surgical variables. Methods: Electronic medical records at two institutions were reviewed for patients who underwent surgical intervention for metacarpal fractures. Data were collected from those who underwent reduction and internal fixation with either plates or Kirschner wires (K-wires). Inclusion criteria included minimum postoperative follow-up of 60 days and age 18 years or older. Exclusion criteria included insufficient radiographic data, previously attempted closed reduction with immobilization, pathologic fracture mechanism, history of previous trauma or surgery to the affected bone, and fixation technique other than plate or K-wire. Results: We reviewed data for patients treated over a 22-year time period. Ultimately, 81 metacarpal shaft and neck fractures in 60 patients met inclusion criteria. Among all metacarpal fractures, complications were present in 39 (48.1%) cases. There were no significant associations between complication prevalence and hardware type. Revision surgery was required in 11 (13.6%) patients; there were no significant associations between revision procedures and hardware type. Postoperatively, all patients with imaging data had radiograph follow-up to assess union status. There was no significant association between time to union and hardware type. Conclusions: Outcomes showed no significant difference between plate and pin fixation for metacarpal shaft and neck fractures. These findings suggest that surgeons may have flexibility to decide on the type of operative intervention while considering patient-specific factors, such as the need for early mobilization.

Background: Distal radius fractures (DRFs) are common geriatric fractures with the overall incidence expected to increase as the population continues to age. The purpose of this investigation was to compare the short-term complication rates in geriatric versus nongeriatric cohorts following osteosynthesis of DRFs. Methods: The American Board of Orthopaedic Surgery (ABOS) part II database was queried for adult DRF cases performed from 2007 to 2013. Current Procedural Terminology codes were used to identify cases treated via osteosynthesis. Patient demographic information and reported complication data were analyzed. Comparisons between geriatric (age ≥65 years) and nongeriatric (age <65 years) patients were performed. Results: From 2007 to 2013, a total of 9867 adult DRFs were treated via osteosynthesis by ABOS part II candidates. Geriatric patients comprised 28% of the study cohort. Mean age of the geriatric and nongeriatric cohorts was 74 ± 7 and 46 ± 13 years, respectively. There was a greater proportion of female patients ( P < .001) in the geriatric cohort as compared with the nongeriatric cohort. The geriatric cohort demonstrated higher rates of anesthetic complications ( P = .021), iatrogenic bone fracture ( P = .021), implant failure ( P = .031), loss of reduction ( P = .001), unspecified medical complications ( P = .007), and death ( P = .017) than the nongeriatric cohort. The geriatric cohort also showed lower rates of nerve palsy ( P = .028) when compared with the nongeriatric cohort, though no differences in rates of secondary surgery were noted between the two cohorts. Conclusion: Increased rates of complications related to poor bone quality and poor health status may be expected among geriatric patients following osteosynthesis of DRFs. However, geriatric and nongeriatric patients have similarly low rates of secondary surgery. Future studies are needed to delineate the economic, functional, and societal impact of geriatric DRFs treated via osteosynthesis.

Background: The aim of this study was to assess national trends in the utilization and complication rates of total wrist arthroplasty (TWA) and total wrist fusion (WF) as identified via review of the American Board of Orthopedic Surgery (ABOS) Part II candidate database. Methods: The ABOS Part II candidate database is a collection of cases reported by candidates of the ABOS Part II board certification oral exam. The ABOS database was queried for all TWA and WF cases performed from 2005 to 2014. Linear regression analyses were used to assess trends in procedure utilization. Treatment diagnoses, patient characteristics, and reported complications were also compared between the 2 treatment cohorts. Results: No significant increases in the proportion of candidates performing TWA or WF, number of TWA or WF cases, nor the number of TWA or WF cases performed per candidate performing those procedures were noted during the study period. Significantly less TWA cases were performed when compared with WF cases (68 vs 327; P = .006). Patients undergoing TWA were significantly older ( P = .005), more likely female ( P < .001), and more likely to have a diagnosis of osteoarthritis ( P = .003) than patients undergoing WF. There were no significant differences in complication rates, including postoperative infection, nerve palsy, or rate of secondary surgery, between the TWA and WF cohorts. Conclusions: Utilization of both TWA and WF has remained unchanged among emerging career orthopedic surgeons. Although WF is performed nearly 5 times more frequently than TWA, our short-term findings suggest that TWA compares favorably with WF.
