Background: The aim of this study was to analyse mid-shaft clavicle fractures in children and adults to find out the factors that would influence the healing time and the necessity of surgical intervention.

Methods: We identified all the midshaft clavicle fractures treated at Chesterfield Hospital between January 2003 and January 2006. We studied the case notes and radiographs of these patients. We grouped the midshaft fractures into those in children and those in adults. Each group was further subdivided into two part and three part fractures. It was also noted whether a vertical butterfly fragment was present in the three or more part fractures. The fractures were analysed for their incidence, presence of comminution, degree of displacement, type of treatment and the follow-up time before discharge.

Results: – Over the 3 year period, 242 middle 1/3 clavicle shaft fractures were treated. Among the mid shaft fractures there were one hundred and eight (44.6%) children and one hundred and thirty four (55.3%) adults.

There were one hundred and three children with two part clavicle fracture (95.3%) and one required surgical fixation (1%). There were only five children with three or more fracture fragments (4.7%) and one required surgical fixation (20%). All five children who had three or more fracture fragments were found to have vertical fragment on x-ray. The average time for discharge was 27.48 days for two part fractures and 49 days for three part fractures.

There were seventy-five (55.5%) adults with two part fractures and ten of them required surgical fixation (13.3%). There were fifty-nine (44.0%) with three or more fragments and eleven of them required surgical fixation (18.6%). Out of the fifty-nine fractures, which had three or more fragments, forty-eight had vertical fragment on x-ray (81.3%). Among the three part fractures, there were ten fractures with vertical fragment that required surgical fixation (20.8%).

The average time for discharge was 52.07 days for two part fractures and 93.56 days for fractures with three or more fragments. There was no difference in the discharge time for non operated three part fractures with or without vertical fragment.

Conclusion: The incidence of clavicle fractures in children is nearly as high as in adults. In children the number of days for discharge is nearly double for three part fractures when compared to two part fractures.

The presence of vertical fragment predicts higher rate of surgical intervention required due to either delayed/non union or localised skin tenting. We recommend that we should have a lower threshold to fix the 3 or more part clavicle fractures with vertical fragment.

Introduction This study was conducted to quantify the incidence of gastrointestinal morbidity and identify risk factors for developing gastrointestinal morbidity following spinal surgery in children.

Method A retrospective review was conducted on 253 surgical spinal procedures performed over a 5 year period at Starship Children’s Hospital. Multivariate logistic regression analysis was used to identify significant risk factors. Co-morbidity included co-existing cardiac, respiratory, genitorurinary or central nervous system problems, or delayed development.

Results Seventy eight (77.9%) percent of the study population developed gastrointestinal morbidity and this significantly prolonged the median post-operative hospital stay (8 days vs.4 days; p< 0.0001). Emesis (50.6%), paralytic ileus (42.3%) and constipation (22.5%) were the most frequent gastrointestinal morbidities. Significant risk factors for developing gastrointestinal morbidity were fusion surgery (p< 0.01), co-morbidities (p-value) and duration of post-operative opioid use (p-value).

Discussion There is a high incidence of gastrointestinal morbidity after paediatric spinal surgery. The consequent prolonged hospital stay has clinical implications to both the patient and the institution. We have further identified risk factors for developing gastrointestinal morbidity, of which the duration of post-operative opioid use is modifiable. Awareness of those with the other significant risk factors identified by this study could assist in the timely implementation of appropriate treatment.
