The reliability of the tip apex distance measurement, the Cleveland femoral head dividing system, the three-grade classification system of Baumgaertner for fracture reduction, and the AO classification system as predictors for screw cutout. Methods: All patients with an intertrochanteric hip fracture who were managed with either a dynamic hip screw or a gamma nail between January 2007 and June 2010 were evaluated from our hip trauma database. Results: The tip apex distance measurement was reliable and patients with device cutout had a significantly higher tip apex distance. The agreement between observers with regard to screw position and fracture reduction was moderately reliable. After adjustment for tip apex distance and screw position, A3 fractures were at more risk of cutout compared with A1 fractures. Poor fracture reduction was significantly related with a higher incidence of cutout in univariate analysis, but not in multivariate analysis. Central-inferior and anterior-inferior positions, after adjustment for tip apex distance and screw position, were significantly protective against cutout. Conclusion: To decrease probable risks of cutout, the tip apex distance needs to stay small or the screw needs to be placed central-inferiorly or anterior-inferiorly.

To identify if functional treatment is the best available treatment for simple elbow dislocations. Electronic databases MEDLINE, EMBASE, LILACS, and the Cochrane Central Register of Controlled Trials. Studies were eligible for inclusion if they were trials comparing different techniques for the treatment of simple elbow dislocations. Results were expressed as relative risk for dichotomous outcomes and weighted mean difference for continuous outcomes with 95% confidence intervals. This review has included data from two trials and three observational comparative studies. Important data were missing from three observational comparative studies and the results from these studies were extracted for this review. No difference was found between surgical treatment of the collateral ligaments and plaster immobilisation of the elbow joint. Better range of movement, less pain, better functional scores, shorter disability and shorter treatment time were seen after functional treatment versus plaster immobilisation.

Background: Upper extremity injuries account for a large proportion of attendances to the Emergency Department. The aim of this study was to assess population-based trends in the incidence of upper extremity injuries in the Dutch population between 1986 and 2008, and to give a detailed overview of the associated health care costs.Methods: Age-standardized incidence rates of upper extremity injuries were calculated for each year between 1986 and 2008. The average number of people in each of the 5-year age classes for each year of the study was calculated and used as the standard (reference) population. Injury cases were extracted from the National Injury Surveillance System (non-hospitalized patients) and the National Medical Registration (hospitalized patients). An incidence-based cost model was applied in order to estimate associated direct health care costs in 2007.Results: The overall age-adjusted incidence of upper extremity injuries increased from 970 to 1,098 per 100,000 persons (13%). The highest incidence was seen in young persons and elderly women. Total annual costs for all injuries were 290 million euro, of which 190 million euro were paid for injuries sustained by women. Wrist fractures were the most expensive injuries (83 million euro) due to high incidence, whereas upper arm fractures were the most expensive injuries per case (4,440 euro). Major cost peaks were observed for fractures in elderly women due to high incidence and costs per patient.Conclusions: The overall incidence of upper extremity injury in the Netherlands increased by 13% in the period 1986–2008. Females with upper extremity fractures and especially elderly women with wrist fractures accounted for a substantial share of total costs.

Purpose The repair of incisional hernias can be accomplished by open or laparoscopic techniques. The Biodex^® dynamometer measures muscle strength during isokinetic movement. The objectives of this study are to compare the strength of the trunk flexors between patients who underwent repair for incisional hernia and a control group, and to compare trunk flexion after two kinds of operative techniques for incisional hernias with and without approximation of the rectus abdominis muscles. Methods The trunk flexion of 30 patients after different operative techniques for midline incisional hernias and of 12 healthy subjects was studied with the Biodex^® isokinetic dynamometer. Results The mean torque/weight (N m/kg) for trunk flexion was significantly higher in the control group compared to the patient group after incisional hernia repair. A significantly higher peak torque/weight [coefficient 24.45, 95% confidence interval (CI) −0.05; 48.94, P = 0.05] was found in the two-layered suture technique without mesh compared to the laparoscopic technique after adjusting for gender. Conclusions The isokinetic strength of the trunk flexor muscles is reduced after an operation for incisional hernia. There is some evidence that a two-layered suture repair with approximation of the rectus abdominis muscles results in higher isokinetic strength of the trunk flexor muscles compared to the laparoscopic technique.

After a complex dislocation, some elbows remain unstable after closed reduction or fracture treatment. Function after treatment with a hinged external fixator theoretically allows collateral ligaments to heal without surgical reconstruction. However, there is a lack of prospective studies that assess functional outcome, pain, and ROM. We asked: (1) In complex elbow fracture-dislocations, does treatment with a hinged external fixator result in reduction of disability and pain, and in improvement in ROM, function, and quality of life? (2) Does delayed treatment (7 days or later) have a negative effect on ROM after 1 year? (3) What are the complications seen after external fixator treatment? During a 2-year period, 11 centers recruited 27 patients 18 years or older who were included and evaluated at 2 and 6 weeks and at 3, 6, and 12 months after surgery as part of this prospective case series. During the study period, the participating centers agreed on general indications for use of the hinged external fixator, which included persistent instability after closed reduction alone or closed reduction combined with surgical treatment of associated fracture(s), when indicated. Functional outcome was evaluated using the Quick Disabilities of the Arm, Shoulder and Hand (QuickDASH; primary outcome) score, the Mayo Elbow Performance Index (MEPI), the Oxford Elbow Score, and the level of pain (VAS). ROM, adverse events, secondary interventions, and radiographs also were evaluated. A total of 26 of the 27 patients (96%) were available for followup at 1 year. All functional and pain scores improved. The median QuickDASH score decreased from 30 (25^th–75^th percentiles [P₂₅–P₇₅], 23–40) at 6 weeks to 7 (P₂₅–P₇₅, 2–12) at 1 year with a median difference of −25 (p < 0.001). The median MEPI score increased from 80 (P₂₅–P₇₅, 64–85) at 6 weeks to 100 (P₂₅–P₇₅, 85–100) at 1 year with a median difference of 15 (p < 0.001). The median Oxford Elbow Score increased from 60 (P₂₅–P₇₅, 44–68) at 6 weeks to 90 (P₂₅–P₇₅, 73–96) at 1 year with a median difference of 29 (p < 0.001). The median VAS decreased from 2.8 (P₂₅–P₇₅, 1.0–5.0) at 2 weeks to 0.5 (P₂₅–P₇₅, 0.0–1.9) at 1 year with a median difference of −2.1 (p = 0.001). ROM also improved. The median flexion-extension arc improved from 50° (P₂₅–P₇₅, 33°–80°) at 2 weeks to 118° (P₂₅–P₇₅, 105°–138°) at 1 year with a median difference of 63° (p < 0.001). Similarly, the median pronation-supination arc improved from 90° (P₂₅–P₇₅, 63°–124°) to 160° (P₂₅–P₇₅, 138°–170°) with a median difference of 75° (p < 0.001). At 1 year, the median residual deficit compared with the uninjured side was 30° (P₂₅–P₇₅, 5°–35°) for the flexion-extension arc, and 3° (P₂₅–P₇₅, 0°–25°) for the pronation-supination arc. Ten patients (37%) experienced a fixator-related complication, and seven patients required secondary surgery (26%). One patient reported recurrent instability. A hinged external elbow fixator provides enough stability to start early mobilization after an acute complex elbow dislocation and residual instability. This was reflected in good functional outcome scores and only slight disability despite a relatively high complication rate. Level IV, therapeutic study.

Purpose Severe traumatic brain injury is a leading cause of mortality and morbidity, and these patients are frequently intubated in the prehospital setting. Cerebral perfusion and intracranial pressure are influenced by the arterial partial pressure of CO₂ and derangements might induce further brain damage. We investigated which lower and upper limits of prehospital end-tidal CO₂ levels are associated with increased mortality in patients with severe traumatic brain injury. Methods The BRAIN-PROTECT study is an observational multicenter study. Patients with severe traumatic brain injury, treated by Dutch Helicopter Emergency Medical Services between February 2012 and December 2017, were included. Follow-up continued for 1 year after inclusion. End-tidal CO₂ levels were measured during prehospital care and their association with 30-day mortality was analyzed with multivariable logistic regression. Results A total of 1776 patients were eligible for analysis. An L-shaped association between end-tidal CO₂ levels and 30-day mortality was observed (p = 0.01), with a sharp increase in mortality with values below 35 mmHg. End-tidal CO₂ values between 35 and 45 mmHg were associated with better survival rates compared to < 35 mmHg. No association between hypercapnia and mortality was observed. The odds ratio for the association between hypocapnia (< 35 mmHg) and mortality was 1.89 (95% CI 1.53–2.34, p < 0.001) and for hypercapnia (≥ 45 mmHg) 0.83 (0.62–1.11, p = 0.212). Conclusion A safe zone of 35–45 mmHg for end-tidal CO₂ guidance seems reasonable during prehospital care. Particularly, end-tidal partial pressures of less than 35 mmHg were associated with a significantly increased mortality.
