“…Labitzke konnte jedoch in einer Vektoranalyse zeigen, dass es bei aktiver Streckung zwar an der Vorderseite zur Kompression, artikularseitig jedoch zu einem Öffnen des Frakturspaltes kommt [28]. Aktuellere biomechanische Untersuchungen stützen diese Aussage und bezeichnen die Zuggurtungsosteosynthese weniger als dynamische, sondern als statische Fixation [29].…”

ZusammenfassungDie Therapie für Patellafrakturen wird in Abhängigkeit von Klinik und radiologischer Diagnostik gestellt. Frakturen mit einer Gelenkstufe kleiner als 2 mm und erhaltener Streckfähigkeit des Kniegelenkes können konservativ behandelt werden. Die Zuggurtungsosteosynthese stellt eine Standardversorgung dislozierter Querfrakturen dar. Limitationen sind in der unzureichenden Stabilisierung von Mehrfragmentfrakturen sowie der hohen Komplikationsrate zu sehen. Die Schraubenosteosynthese mit mindestens zwei Schrauben ist eine Alternative für Querfrakturen mit niedriger Komplikationsrate. Die Kombination aus kanülierten Schrauben mit additiver Zuggurtung durch die Schrauben vereint die Vorteile beider Verfahren. Trotz der höheren Stabilität bleibt die Versorgung von Mehrfragmentfrakturen eingeschränkt. Moderne winkelstabile Platten ermöglichen durch ihre multiplen Schraubenlöcher eine Versorgung von Mehrfragmentfrakturen. Aufgrund ihrer hohen Stabilität ist eine sofortige Vollbelastung möglich. Erste klinische Ergebnisse sind vielversprechend.

“…The traditional tension band is composed of smooth Kirschner wires (K-wire) and stainless wires. The smooth K-wires cannot provide direct fragmentary compression and the fracture may separate when the knee extends [ 11 ]. In addition, when the tension band is working, the stainless wires and K-wires may have stress break, wearing, loosening, migration and skin irritation.…”

Background: Ti-Ni shape-memory patella concentrator (TNSMPC) has been designed as an alternative approach for fixation of patella fracture, which has some advantages like higher hardness, higher tenacity, better wearing resistance, excellent corrosion resistance and desired histocompatibility. The present study was to investigate the efficiency of TNSMPC combined with cannulated compression screws in the treatment of comminuted patella fractures. Methods: Between January 2014 and December 2017, 54 patients of C2 and C3 patella fractures underwent open reduction and internal fixation with TNSMPC combined with cannulated compression screws. All the patients got standard postoperative rehabilitation programs and were regularly followed up for at least 12 months after the operation. X-rays, knee functions and life quality were evaluated during the follow-up. Results: All the patients achieved bone healing and recovery of knee function with low incidence of complications according to outcomes of X-rays and questionnaires. The average operation time and blood loss during surgery were 77.5 ± 25.12 min and 24.25 ± 4.70 ml respectively. The Knee Outcome Survey Activities of Daily Living Scale, the range of motion and the 36-item short-form heath survey after the operation were all improved. According to the Bostman's criteria, the excellent to good rate was 92.6%. Conclusion: TNSMPC combined with cannulated compression screws is an effective internal fixation method for C2 and C3 patella fracture with excellent clinical outcomes. In addition, the operation does not increase extra technique difficulty or tissue damage relatively, which is worth promotion.

“…The smooth K-wires cannot achieve direct fragmentary compression and the fracture may gap in knee extension. [11] In addition, when the tension band is working, the stainless wire and K-wire may have stress break, wearing, loosening, migration and skin irritation. Some orthopedists have presented different modified tension band methods to avoid the shortcomings of traditional tension band,such as cannulated screws combined with stainless wires or cannulated screws combined with titanium cables.…”
