Early Operative Intervention Is Associated With Better Patient Survival in Patients With Intracapsular Femur Fractures But Not Extracapsular Fractures

The purpose of this study was to determine patients' survival after undergoing an early or delayed operation. We retrospectively assessed 1849 files of patients operated for proximal femoral fracture, divided into two diagnostic groups: intracapsular (n = 640) and extracapsular (n = 1209). 1163 (63%) were treated within 48 h from hospital admission and 686 (37%) were treated > 48 h afterwards. Delayed operation in patients with intracapsular fractures was associated with a 1.8-fold excess risk for 1-year mortality (HR = 1.83, P = 0.008), while no effect was observed for patients with extracapsular fractures. Males had a higher HR for mortality in both diagnostic groups. Early surgical intervention is beneficial for intra-capsular femoral fractures; male gender and a high ASA score are associated with an increased mortality hazard risk.     

Posterior-only correction of Scheuermann kyphosis using pedicle screws: economical optimization through screw density reduction

Introduction

Posterior-only approach using pedicle screws’ fixation has emerged as the preferred surgical technique for Scheuermann kyphosis (SK) correction. Insertion of multiple pedicle screws while increasing stability increases also the risk of complications related to screw malpositioning and surgical cost. The optimal screw density required in surgical correction of SK remains unclear. This study compares the safety and efficacy of low screw density (LSD) versus high screw density (HSD) technique used in posterior-only correction of SK.

Methods

Twenty-one patients underwent surgical correction of SK between 2007 and 2011 and were reviewed after a mean of 29 months. HSD technique (i.e., 100 % of available pedicles, averaged 25.2 ± 4 screws) was used in 10 cases and LSD technique (i.e., 54–69 % of available pedicles in a pre-determined pattern, averaged 16.8 ± 1.3 screws; p < 0.001) was used in 11 cases. Kyphosis correction was assessed by comparing thoracic kyphosis, lumbar lordosis and sagittal balance on preoperative and postoperative radiographs. Cost saving analysis was performed for each group.

Results

Preoperative thoracic kyphosis, lumbar lordosis and sagittal balance were similar for both groups. The average postoperative kyphosis correction was similar in both HSD and LSD groups (29° ± 9° vs. 34° ± 6°, respectively; p = 0.14). Complication occurred in four patients (19 %) in the HSD group and in two patients (9 %) in the LSD group (p = 0.56). Three patients required re-operation. Compared to HSD using LSD saves 4,200£ per patient in hardware and 88,200£ for the entire cohort.

Conclusion

LSD technique is as safe and effective as HSD technique in posterior-only correction of SK. Implant-related cost could be reduced by 32 %.     

Understanding Utilization of Outpatient Clinics for Children with Special Health Care Needs in Southern Israel

To understand the pattern of utilization of ambulatory care by parents of children with special health care needs (CSHCN) and to explore parental challenges in coping with health maintenance of their infants after discharge from a neonatal intensive care unit (NICU). CSHCN require frequent utilization of outpatient ambulatory clinics especially in their first years of life. Multiple barriers are faced by families in disadvantaged populations which might affect adherence to medical referrals. Our study attempts to go beyond quantitative assessment of adherence rates, and capture the influence of parental agency as a critical factor ensuring optimal utilization of healthcare for CSHCN. A prospective, mixed-methods, cohort study followed 158 Jewish and Bedouin-Arab infants in the first year post discharge from NICU in southern Israel. Rates of utilization of ambulatory clinics were obtained from medical records, and quantitative assessment of factors affecting it was based on structured interviews with parents at baseline. Qualitative analysis was based on home visits or telephone in-depth interviews conducted about 1 year post-discharge, to obtain a rich, multilayered, experiential perspectives and explained perceptions by parents. Adherence to post-discharge referrals was generally good, but environmental, cultural, and financial obstacles to healthcare, magnified by communication barriers, forced parents with limited resources to make difficult choices affecting utilization of healthcare services. Improving concordance between primary caregivers and health care providers is crucial, and further development of supportive healthcare for CSHCN in concordance with parental limitations and preferences is needed.     

Evaluation of the NiTi Shape Memory BioDynamix ColonRing™ in colorectal anastomosis: first in human multi-center study

Background   

Shape-memory compression bowel anastomosis using a nickel and titanium alloy may reduce leak rates and eliminate foreign anastomotic material. Its safety and efficacy had been demonstrated by animal studies. We conducted the first prospective multi-center clinical evaluation of the safety and effectiveness of BioDynamix anastomosis with ColonRing™ for large-bowel end-to-end or side-to-end anastomosis.
