Comparison of Short-Arm Immobilization and Long-Arm Immobilization in Conservatively Managed Distal Radius Fractures: A Meta-Analysis and Systematic Review.

Distal radius fractures are often treated conservatively with immobilization. Immobilizing above the elbow limits forearm rotation, though recent literature has suggested the effects on radiographic or functional outcomes may be negligible. This systematic review and meta-analysis aimed to analyze the radiographic and functional outcome scores of distal radius fractures managed with short-arm (SA) immobilization and long-arm (LA) immobilization. An electronic systematic search was performed of the PubMed and EMBASE databases from inception to October 5, 2022. All randomized controlled trials (RCTs) involving patients with acute distal radius fractures undergoing nonoperative treatment (involving application/maintenance of immobilization) comparing above-elbow versus below-elbow constructs were included. The outcomes of interest were changes in radiographic parameters (loss of volar tilt [VT], radial height [RH], and radial inclination [RI]), loss of reduction, requirement for surgery, and patient-reported functional outcomes (Disabilities of the Arm, Shoulder, or Hand [DASH] or Quick DASH survey). The Cochrane Risk of Bias Tool 2.0 was used for study quality assessment. The effect size of the interventions was assessed using random effect models to calculate mean differences (MDs) for continuous variables and odds ratios (ORs) for categorical variables. Standardized mean difference (SMD) was calculated for patient-reported functional outcome scores. Nine studies involving 983 cases were included, including 497 SA and 486 LA. No statistically significant differences were observed with regards to VT (P = 0.83), RH (P = 0.81), RI (P = 0.35), loss of reduction (P = 0.33), requirement for surgery (P = 0.33), or patient-reported functional outcomes (P = 0.10). There was no difference in radiographic outcomes, need for surgery, or functional scores among patients treated with SA and LA immobilization. Utilizing SA immobilization is a safe option for conservative management of distal radius fractures and the benefits of mitigating complications associated with LA immobilization may supersede the theoretical limited forearm rotational stability observed with SA immobilization. Further study is required to determine the optimal method of SA immobilization.

Outcomes of hip fracture surgery during the COVID-19 pandemic.

PURPOSE: To investigate if changes to hospital operational models during the COVID-19 pandemic negatively impacted overall time to surgery (TtS) as well as morbidity and mortality rates of hip fractures (HFx). METHODS: 416 patients treated for OTA 31 fractures at a single institution between January 2019 and November 2020 were reviewed. TtS as well as morbidity and mortality rates were obtained from pre-pandemic and pandemic groups. RESULTS: 263 patients were treated pre-pandemic and 153 were treated during the pandemic. There were no significant differences in median TtS, readmission rates (p = 0.134), reoperation rates (p = 0.052), 30-day (p = 0.095) and 90-day (p = 0.22) mortality rates. CONCLUSION: Reallocation of hospital resources in response to the COVID-19 pandemic did not negatively impact surgical timing or complications. TtS for HFx remains a challenge and often requires multidisciplinary care, which is complicated by a pandemic. However, this study demonstrates HFx standard of care can be maintained despite COVID-19 obstacles to treatment efficiency and efficacy.

Implant Removal Due to Infection After Open Reduction and Internal Fixation: Trends and Predictors.

Background: Implant removal due to infection is one of the major causes failure following open reduction and internal fixation (ORIF). The aim of this study was to determine trends and predictors of infection-related implant removal following ORIF of extremities using a nationally representative database. Methods: Nationwide Inpatient Sample data from 2006 to 2017 was used to identify cases of ORIF following upper and lower extremity fractures, as well as cases that underwent infection-related implant removal following ORIF. Multivariate analysis was performed to identify independent predictors of infection-related implant removal, controlling for patient demographics and comorbidities, hospital characteristics, site of fracture, and year. Results: For all ORIF procedures, the highest rate of implant removal due to infection was the phalanges/hand (5.61%), phalanges/foot (5.08%), and the radius/ulna (4.85%). Implant removal rates due to infection decreased in all fractures except radial/ulnar fractures. Tarsal/metatarsal fractures (odds ratio (OR)=1.45, 95% confidence interval (CI): 1.02-2.05), and tibial fractures (OR=1.82, 95% CI: 1.45-2.28) were identified as independent predictors of infection-related implant removal. Male gender (OR=1.67, 95% CI: 1.49-1.87), Obesity (OR=1.85, 95% CI: 1.34-2.54), diabetes mellitus with chronic complications (OR=1.69, 95% CI: 1.13-2.54, P<0.05), deficiency anemia (OR=1.59, 95% CI: 1.14-2.22) were patient factors that were associated with increased infection-related removals. Removal of implant due to infection had a higher total charge associated with the episode of care (mean: $166,041) than non-infection related implant removal (mean: $133,110). Conclusion: Implant removal rates due to infection decreased in all fractures except radial/ulnar fractures. Diabetes, liver disease, and rheumatoid arthritis were important predictors of infection-related implant removal. The study identified some risk factors for implant related infection following ORIF, such as diabetes, obesity, and anemia, that should be studied further to implement strategies to reduce rate of infection following ORIF.

Management of long bone fractures in patients with cerebral fat embolism syndrome.

Fat embolism syndrome (FES) is a rare complication associated with long bone fractures. Intramedullary nailing is the gold standard for treating patients with these injuries and early surgical intervention can prevent FES. However, there is a paucity of data on managing these patients once FES has developed. The purpose of this study is to present 3 unique cases of polytrauma patients with long bone fractures who underwent fixation with Taylor Spatial Frame, open reduction and internal fixation, or submuscular plating for treatment of these injuries. All 3 patients had complete cognitive and physical recovery.

Open Reduction Internal Fixation of a Medial Epicondyle Avulsion Fracture With Incarcerated Fragment.

PURPOSE: The purpose of this video is to present a technique for open reduction and internal fixation of a displaced unstable medial epicondyle avulsion fracture. METHOD: A 13-year-old boy presented 2 days after injury at our institution after sustaining a medial epicondyle avulsion fracture with incarcerated fragment and posterolateral dislocation of the elbow after a fall off a fence. He described paresthesia in the ulnar nerve distribution and demonstrated slight weakness to intrinsic hand strength on examination. He was urgently reduced under sedation in the emergency department using the Roberts maneuver, a technique consisting of a valgus stress with forearm supination with finger and wrist extension that uses muscle forces to extract the fragment. Successful reduction of the ulna-humeral joint and extraction of the incarcerated medial epicondyle was demonstrated on CT. The patient was then taken in a nonurgent fashion to the operating room for open reduction and internal fixation of the displaced medial epicondyle fracture. Intraoperative examination after fixation demonstrated a congruent and stable elbow. A long-arm cast was then applied. RESULTS: The video is 7-minute, 38-second duration in time and 461 MB in size. CONCLUSIONS: Although fixation of medial epicondyle avulsion fractures may be controversial, there are some indications for ORIF including incarcerated epicondylar fragment, suspected entrapment and dysfunction of the ulnar nerve, marked instability of the elbow, and open fracture. Presented in this video is a safe technique for ORIF of the displaced and unstable medial epicondyle avulsion fracture.

Bilateral use of the vertical expandable prosthetic titanium rib attached to the pelvis: a novel treatment for scoliosis in the growing spine.

OBJECT: Few options exist for the treatment of severe, early onset scoliosis. Goals of treatment include stabilizing curve progression while allowing for normal spine, chest, and lung growth. The vertical expandable prosthetic titanium rib (VEPTR) is a novel device designed to control the spine deformity while permitting lung and spine growth. In this paper the authors report their experience with using bilateral VEPTRs from the ribs to the pelvis for children with severe, early onset scoliosis. METHODS: Eleven children were identified who had been treated with bilateral VEPTRs from the ribs to the pelvis. The authors conducted a retrospective review and collected the following data: clinical diagnosis, age at surgery, number of lengthening procedures, and complications. In addition, pre- and postoperative radiographs were reviewed to measure maximum Cobb angle (both thoracic and lumbar), thoracic height, total spine height as measured from T-1 to S-1, thoracic kyphosis (T2-12), and lumbar lordosis (L1-S1). RESULTS: The average patient age at surgery was 71 months; the mean preoperative thoracic Cobb angle was 81.7 degrees . This angle was corrected to 50.6 degrees immediately postoperatively, and this correction was maintained; at the most recent follow-up the curves averaged 58 degrees . Similarly, the preoperative kyphosis (T2-12) angle measured 43 degrees preoperatively, 23 degrees immediately postoperatively, and 37 degrees at the most recent follow-up evaluation. The patients underwent a total of 41 lengthening procedures (average 3.7 lengthening procedures per patient), and overall spine length increased from 23.1 cm preoperatively, to 27.3 cm immediately postoperatively, to 29.4 cm at the final follow-up (an average of 25 months). Four (36.4%) of the 11 patients experienced complications. CONCLUSIONS: The VEPTR offers a viable treatment option for children with severe, early onset scoliosis. It achieves and maintains spinal deformity correction, while allowing for continued spine and chest-wall growth. Complication rates are similar to those reported for other growing systems.
