“…[22][23][24][25] In a systematic review of the literature by Papadokostakis et al, [24] it was concluded that retrograde IM nailing was a reliable treatment method with less complications for distal femoral fractures, while similar judgments were made by Handolin et al [25] Retrograde IM nails have been shown to achieve good results in osteoporotic bone as well. [22,23] The study of Zlowodzki et al [26] discussed that Less Invasive Stabilization System provided improved distal fixation compared to the retrograde nail in osteoporotic bones because of higher axial loads, load to failure and a lower incidence of fixation failure. In addition, displacement at the fracture site was lower.…”

Background:Distal femur fractures are difficult to manage and the selection of implant for internal fixation remains controversial. The objective of this study is to establish the relative strength of fixation of a distal femoral locking plate (DFLP) compared with the dynamic condylar screw (DCS) in the distal femur fractures.Materials and Methods:Study was conducted on 16 freshly harvested cadaveric distal femoral specimens, eight implanted with DCS and other eight with DFLP. The construct was made unstable by removing a standard sized medial wedge of 1 cm base (gap-osteotomy) beginning 6 cm proximal to the lateral joint line in distal metaphyseal region with the loss of medial buttress. Fatigue test was conducted under load control mode at the frequency of I Hz. Specimens were subjected to cyclic loading of 2 kN, under observation for 50,000 cycles or until failure/cutout, which ever occurred earlier.Results:In DFLP group, there was no implant failure and the average number of cycles sustained was 50,000. Six out of eight specimens completed 50,000 cycles and two failed in DCS group. The average number of cycles sustained by DCS was 46150. Though the bone quality as assessed by dual energy X-ray absorptiometry DEXA was comparable in both DFLP and DCS group (P = 0.06), none failed in DFLP group and subsidence was 1.02 ± 0.34 mm (range: 0.60-1.32 mm), which was significantly 43% lower (P = 0.006) than subsidence in DCS group (1.82 ± 0.58; range: 1.20-3.08 mm). The average stiffness of DCS group was 52.8 ± 4.2 N/mm, which was significantly lower than average stiffness of locked condylar plate group (71.2 ± 5.1 N/mm) (P = 0.02).Conclusions:DFLP fixation of the distal femur fractures resulted in stronger construct than the DCS fixation in both cyclic loading and ultimate strength in biomechanical testing of a simulated A3 distal femur fracture.

“…Mehrere klinische Studien zeigen, dass das LISS hinsichtlich des funktionellen Ergebnisses mit konventionellen Plattenosteosynthesen, aber auch mit Marknagelosteosynthesen vergleichbar ist [8][9][10]. Bei den Heilungsraten ist das minimalinvasive Vorgehen der konventionellen Plattenosteosynthese überlegen und mit den Resultaten der Marknagelung vergleichbar; primäre oder sekundäre Spongiosaplastiken werden nur sehr selten notwendig [3,4,7,11].…”

“…Several clinical studies show the LISS to be comparable in functional results not only to conventional plate osteosynthesis but also to intramedullary nailing [8][9][10]. With regard to recovery rates, the minimally invasive procedure has been shown to be superior to conventional plate osteosynthesis and similar to intramedullary nailing; primary or secondary cancellous bone grafting was only very rarely necessary [3,4,7,11].…”

Between May 1998 and September 2001, a total of 42 patients had their distal femoral fractures stabilized by LISS. The AO distractor was used from the 18th case onward. A time saving of approximately 13% was estimated, taking the learning curve of the LISS system into consideration. Three of 42 fractures showed relevant postoperative varus or valgus malalignment. No rotational malalignment was found. An effect of the LISS tractor on the incidence of malalignment could not be found with the limited number of cases examined; however, malalignment was correlated well with the rates found in literature for distal femoral fractures.
