INCIDENCE AND TIME TREND OF HIP FRACTURES IN ROMANIA: A NATIONWIDE STUDY FROM 2008 TO 2018

Osteoporotic Hip Fracture Incidence Rates in the Main Urban Area of Romania

CONTEXT

Estimation of osteoporotic hip fracture incidence and Romanian FRAX model were based on nationally reported hospital ICD 10 coding admissions of all hip fractures (without a validation process).

OBJECTIVE

We aimed to calculate, based on individual hospital charts analysis, the incidence of osteoporotic hip fracture in the main urban area of Romania and compare it with data reported to the National Institute of Public Health (NIPH).

DESIGN

We retrospectively analyzed the charts of all patients (>40 years old) admitted for hip fracture in a 12-month period in hospitals with an Orthopedic Department in Bucharest and surrounding Ilfov County (11.8% of Romania population).

SUBJECTS AND METHODS

All ICD 10 fracture and event/fall codes were validated against the charts. We calculated the age and sex adjusted incidence of osteoporotic hip fracture and used the national reported hip fracture data base for comparison.

RESULTS

There were 2203 hip fractures of which 1997 (90.65%) were fragility fractures. The crude incidence of low-energy hip fractures was 171/100,000 (225/100,000 in women, 103/100,000 in men). The incidence rose with age to a maximum rate of 1902/100,000 in women >85 years. The NIPH-reported incidence of hip fracture was 181/100,000 for the region of interest and 176/100,000 at the national level.

CONCLUSION

The incidence of osteoporotic hip fracture was lower than the incidence based on hip fractures reported codes in the national database, but the incidence of fragility fractures calculated by our group was higher than the incidence reported in previous national studies. Nationwide studies are warranted.

A new perspective towards failure of gamma nail systems

Uncommon causes of nail failures and surgical reinterventions were determined. The study included 23 osteoporotic patients, 13 of whom followed a fast recovery program with early walking (FWB group). The other 10 patients were not allowed full weight bearing until 6 weeks (NFWB group). The T-score was determined before surgery for all cases. A case with a nail breakage after a failed DCS implant fixed in another clinic was also analyzed. The nail was revised and the broken implant underwent a metallurgic and microscopic examination. The average T-score was 2.5 for the patients that followed the fast recovery program and 2.7 for the patients from non-full weight bearing. Four patients, 1 from the NFWB group and 3 from FWB group, presented a screw cut-out. It was found that the errors of the guiding instruments may create dents, scratches or micro-fractures on the titanium coating that lead to an early implant failure. Imperfect reduction leads to incorrect implant placement and a high incidence of failure. Damaging the titanium protective coating, in a low force, high cycles scenario can cause structural failure. Delays in fracture healing and material fatigue are the most common causes of nail failure and can lead to catastrophic complications.
