Spontaneous resolution of a 'ping-pong' fracture at birth

Obstetric factors and neonatal outcomes of depressed skull fractures in newborns

PURPOSE

To determine the obstetric factors affecting the development of depressed skull fracture in neonates.

MATERIALS AND METHODS

This was a retrospectively cohort study on neonates born between July 2016 and August 2021. Neonates diagnosed with depressed skull fractures within one week of birth through X-ray and/or brain ultrasonography were included, and their mothers' obstetric characteristics were reviewed.

RESULTS

There were 12 cases in 6791 live births. Five women were over 35 years old. All except two were nulliparous. Five cases were delivered from labor induction and others presented with spontaneous labor. Except for two cases, delivery occurred within an hour after full cervical dilatation. Two cases were assisted by vacuum. None displayed fetal distress signs such as low Apgar scores below 7, meconium staining, and umbilical cord pH under 7.2. All depressed fractures were found in the right parietal area. Three cases resulted in focal hyperechoic lesion in brain ultrasonography and two of them showed small hemorrhage-like lesion in magnetic resonance imaging. All depressed skull fractures improved within 6 months in followed X-rays or ultrasonography.

CONCLUSIONS

There was no definitely associated obstetric condition for depressed skull fracture of neonates although nulliparous women were majority of the affected cases.

Elevation of Depressed Skull Fracture in Neonates Using a Breast Pump and a Custom-Molded Flange

BACKGROUND AND IMPORTANCE

"Ping-pong fractures" (PPF) can occur in neonates and result in cosmetic deformity and local mass effect. Standard treatment involves surgical elevation of the depressed bone when the indentation is considerable or cosmetically apparent. Surgical correction of PPF subjects patients to the risks of surgery and general anesthesia. This article and corresponding video demonstrate a novel means of correcting PPF at bedside without surgery or anesthesia. We used a hospital-grade breast pump connected to a custom-fabricated flange to successfully elevate PPF in two neonates.

CLINICAL PRESENTATION

Two moderately preterm infants were noted at birth to have large parietal PPF. To avoid surgical intervention, elevation using a suction device was attempted. A hospital-grade breast pump was used to provide suction. A custom device was fabricated out of a breast pump flange and molded Coloplast Brava® protective seal rings. This device was carefully applied to the skull to exactly match the diameter of the PPF and contour of the bone. Brief (15-30 seconds) periods of suction were applied several times until the PPF was successfully elevated as documented on subsequent computed tomography scans. Both infants achieved excellent cosmetic results with no adverse effects over 24- and 9-month follow-ups, respectively.

DISCUSSION

This technique eliminates the risks of open surgical correction and corrected the PPF without general anesthesia or adverse effects to the infant. While there may be limitations due to patient age and/or location of the PPF, the use of widely available and inexpensive custom-fitted materials with a hospital grade breast pump achieves maximal efficacy without requiring higher negative pressure suction application.

CONCLUSION

Elevation of PPF can be safely achieved in some neonates using readily available equipment: a hospital-grade breast pump, flange, and moldable adherent material. This technique is reasonable to attempt in lieu of surgical elevation.

[Determination of severity of harm caused to health in depressed skull deformation by «ping-pong» type in an infant]

THE OBJECTIVE

Is to develop a differential approach to determining the severity of harm caused to health in case of depressed skull injuries in infants, depending on their morphological features and the character of required treatment. The material included data from literature sources on the study of brain injuries in infants, clinical guidelines, describing the features of clinical picture and diagnosis of depressed skull fractures in infants and legal and regulatory framework of forensic medical evaluation of harm caused to health in injury. The following methods of research were used: logical-analytical, logical-synthetic (generalization), comparative, system-analytical (analysis of relations between facts) and radiological method. An algorithm for determining the severity of harm caused to health in depressed skull deformations by «ping-pong» type in an infant is proposed for discussion. The algorithm is based on the data from injury imaging techniques, including X-ray computed tomography, takes into account the clinical picture and the availability of indications for surgical treatment, and will allow to objectively assess the severity of harm caused to health in such cases.
