Acetabular All-Suture Anchor for Labral Repair: Incidence of Intraoperative Failure due to Pullout.

PURPOSE: To report on the incidence and features of intraoperative anchor pullout in a consecutive series of patients undergoing arthroscopic labral repair of the hip. METHODS: Over an 18-month period, 434 consecutive cases underwent labral repair by a single surgeon with a particular anchor system. The following data were recorded: (1) age and gender of all cases; (2) number of anchors used; (3) number of cases in which intraoperative anchor failure occurred; (4) number of anchors that failed; and (5) age and gender of those cases in which anchor failure occurred. Failures were reported for 3-month intervals. One patient underwent repair with an alternative anchor system during this time period and was excluded. RESULTS: Mean age was 34.2 (14-71) years with 180 males and 254 females. A total of 2,007 anchors were used, averaging 4.6 per case (1-8). Thirty-three anchors pulled out among 30 patients, representing a 1.6% incidence among all anchors. Mean age among pullouts was 37.8 (17-54) years with 11 males and 19 females. There was no difference compared with patient population in which no anchor pulled: mean 33.9 (14-71) years (P = .085) with 169 males and 235 females (P = .578). Pullouts were evenly distributed over the 3-month intervals (4, 4, 6, 6, 5, 8). Pullout was mostly due to failure to securely imbed the anchor in bone. Only 2 were known to pull out in the presence of being securely seated in bone. CONCLUSIONS: These data support that the security of this particular all-suture anchor at implantation is exceptionally reliable for a single experienced surgeon, and there is no demonstrable learning curve. LEVEL OF EVIDENCE: Level IV, retrospective review of a case series.

Tub bathing improves thermoregulation of the late preterm infant.

OBJECTIVE: To compare body temperature of the late preterm infant after 24 hours of life at three time points before and after immersion tub bathing or sponge bathing. We hypothesized that late preterm infants achieve significantly improved thermoregulation when bathed by immersion tub bath compared to traditional sponge bathing. DESIGN: This study was a randomized controlled trial. SETTING: A large metropolitan teaching hospital in the northeastern United States. POPULATION: Late preterm infants (100) born between 35 and 36 6/7 weeks gestation, bathed in the well-baby nursery of a 30-bed mother/baby unit. METHODS: Infant participants were identified and informed consent was obtained from the parent. Infants were randomized into two groups: 50 bathed by sponge and 50 bathed by immersion tub. Infant body temperature was measured at three time points: 10 minutes prior to bathing, 10 minutes following bathing, and 30 minutes following bathing. RESULTS: Infants who were tub bathed experienced significantly less variability in body temperature and overall were warmer 10 minutes and 30 minutes following the bath compared to infants who were sponge bathed (p = .024). CONCLUSION: The study findings support the hypothesis that late preterm infants who are tub bathed experience significantly less body temperature variability and an overall higher body temperature following the bathing procedure.
