Scapular thickness--implications for fracture fixation.

The purpose of this study was to measure and map scapula osseous thickness to identify the optimal areas for internal fixation. Eighteen (9 pairs) scapulae from 2 female and 7 male cadavers were used. After harvest and removal of all soft tissues, standardized measurement lines were made based on anatomic landmarks. For consistency among scapulae, measurements were taken at standard percentage intervals along each line approximating the distance between two consecutive reconstruction plate screw holes. Two-mm-diameter drill holes were made at each point, and a standard depth gauge was used to measure thickness. The glenoid fossa (25 mm) displayed the greatest mean osseous thickness, followed by the lateral scapular border (9.7 mm), the scapula spine (8.3 mm), and the central portion of the body of the scapula (3.0 mm). To optimize screw purchase and internal fixation strength, the lateral border, the lateral aspect of the base of the scapula spine, and the scapula spine itself should be used for anatomic sites of internal fixation of scapula fractures.

Postnatal malnutrition of extremely low birth-weight infants with catch-up growth postdischarge.

OBJECTIVE: To assess nutritional intakes and subsequent growth of extremely low birth-weight (BW) infants. STUDY DESIGN: Chart review of 69 extremely low BW infants stratified into two groups by BW: < or =750 g (group 1; n=27) or 751 to 1000 g (group 2; n=42). Dietary intakes, weights, and head circumferences (HC) were collected through discharge and at 1 month postdischarge. The differences between goals and intakes were calculated weekly during hospitalization. Descriptive comparisons were made between growth parameters at birth, discharge, and follow-up. RESULTS: Total energy and protein deficits were inversely related to BW. Both groups exhibited extrauterine growth retardation while hospitalized. After discharge, the rates of weight gain and HC growth increased, leading to some growth recovery at follow-up. CONCLUSIONS: Existing feeding methods resulted in sizeable deficits in energy and protein, particularly for the smallest infants. Changing current practices to limit these deficits is essential to improving postnatal growth.

Prediction of extrauterine growth retardation (EUGR) in VVLBW infants.

BACKGROUND: Long-term growth failure in very very low birth weight (VVLBW) infants is a common complication of extreme prematurity. Critical illnesses create challenges to adequate nutriture. PURPOSE: To identify predictors of extrauterine growth retardation (EUGR) in VVLBW infants and to evaluate their nutritional intake and subsequent growth. STUDY DESIGN: A 4-year retrospective chart review of 221 infants <or=1000 g birth weight and <or=29 weeks gestational age who were admitted within 24 hours of birth, were free of major congenital anomalies and survived at least 7 days. Daily intakes and anthropomorphic data were collected and analyzed. Significant events during hospitalization were documented. RESULTS: Mean energy and protein intakes during hospitalization did not reach recommendations of 120 kcal/kg/d and 3.0 g/kg/day. In utero growth rates could not be consistently reached or sustained. As expected, BW (as measured by BW percentile score) was highly predictive of EUGR (p<0.001). When the independent effect of other predictors of EUGR was considered, only days of total parenteral nutrition (p<0.001) and HC percentile at return to birth weight (p<0.001) made a significant contribution to the prediction of EUGR, once the effect of BW was taken into account.
