Aksoy C, et al compared the results of compression plate fixation and flexible
intramedullary nail insertion.
In this treatment described by the 'Nancy team', nail is selected by measuring 40% of the narrowest diameter of the medullary canal.12 Elastic
intramedullary nail treatment works by balancing the forces between the two opposing flexible implants.
The Cochrane Collaboration, Cochrane Library (Issue 2, 2/12/2011), Ovid MEDLINE (1950 to 10/31/2016), ProQuest, US National Library of Medicine National Institutes of Health, and PubMed electronic databases were searched for clinical studies using the keywords "
intramedullary spinal cord metastasis", "carcinoma metastasis", "renal cell carcinoma", "breast cancer", "intracranial metastasis", "lung adenocarcinoma", and "lung cancer" without any language or country limitation.
Dynamization: The procedure done in cases of delayed union of femoral and tibial shaft fractures fixed with
intramedullary interlocking nail in which screws farthest from the fracture site are removed.
This was however in the setting of
intramedullary (IM) nailing of the tibia.
The fixation combinations were considered, being an
intramedullary pin with external skeletal fastener, an
intramedullary pin with bone plate, and modified or crossed Rush pins (HARARI, 2002; BEALE, 2004; ROUSH, 2005; DeCAMP et al., 2016).
"As compared with
intramedullary screw fixation, plantar-lateral plating allowed for greater cycles to failure and peak load before failure, as well as less gap width, when applied to cadaver foot specimens with simulated Jones fractures exposed to cantilever bending in a load frame," the authors write.
However, lesions in long bones generally appear in the metaphysis as an
intramedullary expansion with a thinning of the bone cortex.
This study was done with objective to study the outcome of operative treatment with flexible
intramedullary nail.
In the group with AFF, intraoperative femoral fracture during
intramedullary nail insertion occurred in 11.8% (2 cases) (Figure 1), and one plate failure occurred (5.9%); there were no nail failures.
Osteotomy for the affected tibia was performed percutaneously using an osteotome on the prepared osteotomy line while retaining the
intramedullary nail (Figure 2(a)).
Unenhanced T1-weighted magnetic resonance imaging (T1WI MRI) is an important preoperative examination used to visualize the
intramedullary extent of malignant long bone tumors.
