intramedullary nail

A metal rod forced into the medullary cavity of long, weight-bearing bones (e.g., femur, tibia), which allows ambulation within weeks rather than months. Intramedullary nails have a cloverleaf appearance on cross-section and are made of titanium, which has a lower rate of mechanical failure and improved biocompatibility.

Complications
Persistent knee pain (present in 3/4 of patients), arthritis (1/3), and atrophy of the quadriceps and calf muscles (1/4).

intramedullary nail

A surgical rod inserted into the intramedullary canal to act as an immobilization device to hold the two ends of a fractured long bone in position.

The mean duration of surgery for InterTan intramedullary nail in the late group of patients was 64.97 (95% CI 59.59 to 70.36) min, similar to the operative time reported in earlier research that ranged from 48 to 73.91 min [4, 5, 15,1 8-20], excluding one study that reported an average time that was less than 30 minutes [21].
Intramedullary nails have added advantages over plating in these cases, like restoration of anatomical length and alignment of comminuted fractures, biological fixation resulting in high union rates, strength for femoral shaft fracture in all three planes of loading - bending, compression, and torsion, early joint mobilisation, early muscle rehabilitation, shortened hospital stay, reduces the incidence of complications like infection, cortical osteopenia, mal-union, and non-union.
Intramedullary nails are routinely used in the treatment of fracture for femur and tibia.
The working prototype consists of a fixed magnet that is placed inside the intramedullary nail and a handheld unit housing the sensors, electronics, and drill sleeve.
(3,5-7) However, no previous case of radial nerve traction injury due to this type of intraoperative positioning during Kuntscher intramedullary nail insertion has been reported in the literature.

An intramedullary nail can be a useful adjunct to this technique.
Overall several different classification systems have been developed including the Russell-Taylor classification which is based on the presence of lesser trochanter comminution and fracture extension into the piriformis fossa which helped to guide treatment prior to the development of trochanteric start point intramedullary nails. The AO classification system also has a classification system describing fracture morphology and mechanism.
Two days after injury, the patient underwent internal fixation with an intramedullary nail via the lateral approach with gentle traction, internal rotation, and adduction using a traction table (Figure 1(b)).
