Objective To investigate the incidence of postoperative overall complications or secondary procedures following distal radius fractures treated by volar locking plate (VLP) Methods Electronic medical records (EMR) of 1152 patients with 1175 distal radius fractures treated by volar locking plate between January 2013 and September 2018 were retrospectively reviewed and the data were extracted. The picture archiving and communication system (PACS) was inquired to assess the fracture severity and to determine the fracture type. Univariate and multivariate logistic regression analyses were used to identify the associated risk factors. Results During the median follow-up period of 6 months, a total of 138 complications in 131 patients were determined, indicating the accumulated rate of 11.7%; there were 68 cases of secondary procedures, with the rate of 5.8%. The independent associated factors for postoperative overall complications were AO type C fracture (OR, 2.6; 95%CI, 1.2 to 4.0), open fracture (OR, 4.2; 95%CI, 1.9 to 6.5), and significant collapse of the lunate fossa (OR, 2.9; 95%CI, 13 to 4.3), and for secondary procedures were significant collapse of the lunate fossa (OR, 3.7; 95%CI, 1.7 to 6.4) and the low-volume of surgeons (OR, 95%CI, 1.2 to 3.6) Conclusions Identification of these factors is of importance for the risk assessment of postoperative complications and the additional need of surgery. For patients with the above factors, especially those with combined risk factors, optimized operation scheme and high-volume surgeon should be considered to prevent or reduce the complications.
Surgical-site infection (SSI) is a common complication in orthopedic surgery; however, SSI after surgically managed distal femur fractures was not well studied. The aim of this study was to investigate the incidence of SSI and identify some modifiable and nonmodifiable risk factors. The patients’ electronic medical records (EMRs) were reviewed to identify those who sustained a distal femur fracture and treated by open reduction and internal fixation (ORIF) between March 2014 and February 2018. SSI was defined based on the Centers for Disease Control criteria and confirmed according to the descriptions in EMR. Univariate and multivariate logistic regression models were used to determine the independent risk factors associated with SSI. Totally, EMRs of 665 patients who underwent ORIF of distal femur fractures were reviewed and 24 SSIs were found, indicating the overall incidence of SSI was 3.6%. The rate of deep SSI was 1.2% and superficial SSI was 2.4%. Staphylococcus aureus was the most common causative pathogen, either alone (7/15, 46.7%) or as a mixed infection (3/15, 20%), followed by mixed bacterial (4/15, 26.7%) and S epidermidis (2/15, 13.3%) and others. Patients with SSI had approximately twice the length of hospital stay as those without SSIs (29.0 vs 16.0 days, P < .001). Open fracture, temporary use of external fixation, obesity, smoking, diabetes mellitus, and preoperative reduced albumin level were identified as independent risk factors associated with SSI, and current smoking and preoperative reduced albumin level were the true modifiable factors. Patients should be encouraged to cease smoking as early as possible and increase the good-quality protein intake to reduce or prevent the occurrence of SSI. An explanation of the nonmodifiable risk factors should be included when patients are counseled about their increased risk of SSI.
Patients with mini-incision approach have satisfactory surgical outcomes, low postoperative complications, and good appearance.
BackgroundIn the treatment of cubital tunnel syndrome (CuTS), in situ ulnar nerve decompression is commonly used. This study aims to investigate predictive factors for poor recovery and ulnar nerve instability following this procedure.MethodsWe enrolled 235 patients who underwent in situ ulnar nerve decompression for the treatment of CuTS from January 2010 to December 2014. All patients underwent >2 years’ follow-up. The primary outcome was postoperative recovery, which was assessed by Messina’s criteria, and the secondary outcome was postoperative ulnar nerve instability. Potential risk factors were collected from demographic data and electrodiagnostic test, which included age, gender, body mass index, history of tobacco or alcohol use, history of major medical comorbidities, disease duration, preoperative severity, motor conduction velocity, and sensory conduction velocity.ResultsA total of 208 patients (88.5%) had satisfactory outcomes, while the other 27 patients (11.5%) had not. There were 25 patients (10.6%) showing postoperative ulnar nerve instability during follow-up. The multivariate analysis showed that only severe preoperative symptom (odds ratio [OR], 3.06; 95% confidence interval [CI], 2.16–4.32) was associated with unsatisfactory postoperative outcomes in patients with CuTS (P<0.001). In the model investigating independent factors associated with postoperative ulnar nerve instability, we found that young age (OR, 2.41; 95% CI, 1.63–3.58) was associated with the incidence of postoperative ulnar nerve instability (P<0.001).ConclusionWe found that severe preoperative symptom was associated with unsatisfactory postoperative outcomes, and young age was a risk factor for the incidence of postoperative ulnar nerve instability. Patients with these risk factors should be informed of the possibility of worse surgical outcomes.
