            ‐Assisted Percutaneous Cannulated Screw Fixation in the Treatment of Femoral Neck Fractures: A Minimum 2‐Year Follow‐up of 50 Patients

Objective: Pediatric femoral neck fractures are uncommon injuries. Accurate early reduction and fixation is recommended to avoid serious long-term complications. The aim of this study was to analyze the clinical and radiological outcomes of 12 children with femoral neck fractures who were treated with closed reduction and cannulated screw fixation. Method: Between November 2015 and December 2019, 12 children (4 males,8 females) with an average age of 9.7 were operated by closed reduction and cannulated screw fixation for femoral neck fractures. We evaluated the medical records of all patients, including age, gender, injury mechanism, fracture type, initial displacement, postoperative reduction, follow-up roentgenograms and Ratliff’s scores. Results: The mean follow-up was 22.3 months (range 12–47 months). Six Delbett type 2, five Delbett type 3 and one Delbett type 4 fractures were operated with an avarage time to surgery of 12.5 (range: 1-75 hours). Satisfactory outcomes according to Ratliff’s criteria were obtained in 10 (%83.3) children. Coxa vara occurred in 2 cases. Any avascular necrosis was not seen during the follow-up period. Conclusion: Early closed reduction and cannulated screw fixation may be effective to avoid long-term complications in pediatric femoral neck fractures.

Abstract Purpose: To investigate the effectiveness of open reduction and cannulated screw fixation via direct anterior approach (DAA) for the treatment of femoral neck fractures in young adults. Methods: The data from 43 young patients with irreducible femoral neck fractures who underwent this procedure from January 2013 to December 2017 were retrospectively analyzed. Garden's alignment index was measured after the operation and at the final follow-up to determine the reduction quality, and the Harris score was recorded at the final follow-up to assess hip function. Results: The average follow-up duration was 19 months (range, 12-31 months). Implant failure was observed in 3 cases and was associated with femoral neck shortening, and nonunion occurred in 2 patients. A total of 6 patients Exhibited features of avascular necrosis (AVN), four of whom (Ficat grade III) underwent total hip arthroplasty and two of whom (Ficat grade II) were asymptomatic at the final follow-up. There were no statistically significant differences in Garden's alignment index, as measured on X-ray radiographs, immediately after surgery and at the final follow-up. At the final follow-up, the mean Harris score was 82.41±14.06. The Harris score was considered excellent for 17 cases, good for 13 cases, fair for 3 cases, and poor for 4 cases. The rate of excellent and good outcomes was 81.1%. Conclusions: For cases of irreducible femoral neck fractures, open reduction and cannulated screw fixation via DAA can yield relatively good clinical outcomes.

Eine Analyse

112 mediale Schenkelhalsfrakturen wurden unabhängig vom Dislokationsgrad bei 110 Patienten mit einem Durchschnittsalter von 78.4 Jahren (25-96 Jahre) zwischen 1.6.97 und 31.12.98 im Rahmen einer prospektiven Beobachtungsstudie kopferhaltend mit einer Schraubenosteosynthese versorgt. Mit einem durchschnittlichen Follow-up von 6.8 Monaten (3-16 Monate) konnten 60 Patienten mit 61 Frakturen klinisch und radiologisch nachkontrolliert werden. 22.7% der Patienten sind während der Beobachtungszeit verstorben. 68.9% der nachkontrollierten Frakturen sind geheilt. Eine Partial- oder Totalnekrose des Hüftkopfes ist in 18%, eine Pseudarthrose in 8.2% und eine Dislokation in 4.9% der Fälle aufgetreten. 18 Patienten (29.5%) mussten reoperiert werden, wobei 1/3 auf Schraubenwechsel oder Schraubenentfernungen, 2/3 auf eine sekundäre Alloarthroplastik entfallen. Bezüglich Schmerzen konnte in 81.6% (unter Ausschluss der mit einer Prothese reoperierten Patienten) ein gutes Resultat erreicht werden. In der Diskussion wird eine Analyse der möglichen Fehlerquellen vorgenommen mit dem Ziel, künftig mit der Schraubenosteosynthese eine noch bessere Heilungsrate zu erzielen.
