Isolated quadrilateral plate fractures are extremely rare and their treatment is complex. The postpartum period and recent caesarean section additionally increase already significant risks of surgical treatment. Modified Stoppa approach and the use of infrapectineal plate represent the optimal surgical treatment method. One case of central hip dislocation and isolated quadrilateral plate fracture was reported during an epileptic seizure 1 day postpartum, which was treated with open reduction and internal fixation. A 25-year-old female patient had given birth via cesarean section. One day postpartum, she had multiple generalized tonic clonic seizures. Arteriovenous malformation was identified as the cause of seizures by MRI. The patient complained of left hip pain and inability to move the left leg which prompted clinical and radiological examination. A pelvic CT scan verified multifragmentary fracture of the quadrilateral plate without fracture of the acetabular columns. The central hip dislocation was verified. Due to the rarity of the fracture, the clinical decision-making process was difficult. The patient, being in the post-partum period, was also at a greater risk of infection. The patient was treated surgically, and osteosynthesis was performed with an infrapectineal plate for the acetabulum using the modified Stoppa approach. The initial incision was done through the same Pfannenstiel incision from caesarean section. The patient's postoperative recovery was good at 1 year follow-up.

PURPOSE: To determine the impact of an earthquake during COVID-19 lockdown on fracture admission at a tertiary trauma centre in Croatia. METHODS: A case-control study was performed at the tertiary trauma centre registry. Two different periods were studied. The case group included a period during COVID-19 lockdown right after the earthquakes until the end of the confinement period in Croatia. And the control group corresponded to the equivalent period in 2019. We identified all consecutive patients who were admitted due to urgent care requirements for the musculoskeletal trauma. Patient's demographic data and admitting diagnoses were assessed. Data were analyzed by statistical procedures using the program MedCalc statistical software version 16.4.3. RESULTS: We identified 178 emergency admissions due to musculoskeletal trauma. During the COVID-19 lockdown and post-earthquake period, there was a drastic reduction in total admissions (359 vs. 662; p < 0.0001) with an increased proportion of trauma admissions within the emergency admissions (34.9% vs. 26.5%; p = 0.02926, Z = -2.1825). Furthermore, in the case group there was a significant increase in hospital admissions due to ankle/foot trauma (11 vs. 2, p = 0.0126) and a trend towards a decrease in the admissions due to tibia fractures (5 vs. 12, p = 0.0896), however without statistical significance. Also, an increased proportion of women within the group of femoral fractures in both case group (81.6% vs. 52.6%, p = 0.00194, Z = 3.1033) and the control group (82.3% vs. 60.5%, p = 0.0232, Z = 2.2742) was observed. In both analyzed periods, the osteoporotic hip fracture was the most common independent admitting diagnosis. CONCLUSION It is crucial to understand how natural disasters like earthquakes influence the pattern of trauma admissions during a coexisting pandemic. Accordingly, healthcare systems have to be prepared for an increased influx of certain pathology, like foot and ankle trauma.
