When Is a Reverse Total Shoulder Replacement the Right Option to Relieve Shoulder Pain? Femur, the thighbone, is the strongest and longest bone in the human body. [QxMD MEDLINE Link]. The proposed theory is that prolonged bisphosphonate use decreases osteoclast activity and inhibits bone remodeling, leading to microdamage that would normally be repaired but is inhibited, thus increasing skeletal fragility 2-4,12. Schnackenburg KE, Macdonald HM, Ferber R, Wiley JP, Boyd SK. The femur is subject to many forces during ambulation including axial loading, bending, and torsional forces. Teriparatide improves bone quality and healing of atypical femoral fractures associated with bisphosphonate therapy. Stress becomes concentrated at susceptible areas with eventual weakening and subsequent microfracture, as these repetitive stresses overcome the ability of the bone to remodel. [Full Text].

[4] This factor is significant, especially in elderly patients who have less cardiac reserve. Diagnosis is made radiographically with radiographs of the femur as well as the hip to rule out ipsilateral femoral neck fractures. reamed nailing superior to unreamed nailing, with: insert femoral nail with 90 of internal rotation, leverages the anterior bow of the nail to direct the tip of the nail into the canal, avoids medial comminution with nail contact along medial cortex, careful mallet nail to appropriate depth after crossing fracture site, computer-assisted navigation for screw placement decreases radiation exposure, obtain perfect trajectory of interlock holes with C-arm transducer, use the angle of the transducer to guide trajectory of drill, widening/overlap of the interlocking hole in the proximal-distal direction, correct with adjustment in the abduction/adduction plane, widening/overlap of the interlocking hole in the anterior-posterior plane, correct with adjustment in the internal/external rotation plane, reamed nailing has been associated with higher union rates compared to unreamed nailing, reaming disrupts endosteal blood supply, but stimulates soft tissue and periosteal blood supply to fracture, periosteal and soft tissue blood supply is predominate source after fracture, reaming extrudes medullary contents into fracture site, increased micro emboli to lungs with reaming, intraoperative echocardiogram studies have not demonstrated this to be significant, mild increases in marrow pressure with reaming, greatest increase occurs with nail insertion, allows canal contents to extrude around the nail, reaming allows are a larger diameter nail to be placed, larger nail is stiffer and is related to the diameter to the 4th power, increases the area of isthmic contact with nail, no increase in infection rates after reaming open fractures, range of motion of knee and hip is encouraged, not indicated for use with ipsilateral femoral neck fracture, increased rate of HO in hip abductors with antegrade nailing, increased rate of hip pain compared with retrograde nailing, mismatch of the radius of curvature of the femoral shaft and intramedullary nails can lead to, 2 cm incision starting at distal pole of patella, medial parapatellar versus transtendinous approaches, useful for eliminating extension moment of gastrocnemius in distal fragment, extension of Blumensaat's line on lateral, posterior to Blumensaat's line risks damage to cruciate ligaments, trajectory in line with the canal on AP and lateral views, requires a curves nail to prevent valgus malalignment, entry reamer with soft tissue protecting sleeve, fracture must be reduced to avoid eccentrically reaming the cortex, ream canal 1 to 1.5 mm greater than size of intended implant, should seat ~1 cm deep to articular surface to prevent patellofemoral symptoms, can place first and then mallet the nail to gain compression at fracture with transverse patterns, perfect circles technique for proximal interlocks, femoral neurovascular bundle safe if screws placed proximal to lesser trochanter, allows for addressing other injuries surgically without changing patient position, allows for direct comparison of rotation and leg length to nonoperative extemity, union rates comparable to those of antegrade nailing, no increased rate of septic knee with retrograde nailing of open femur fractures, increased rate of interlocking screw irritation, cruciate ligament injury with improper starting point, safest pin location sites are anterolateral and direct lateral regions of the femur, 2 pins should be used on each side of the fracture line, prevents further pulmonary insult without exposing patient to risk of major surgery, converted to IM fixation within 2-3 weeks, due to binding/scarring of quadriceps mechanism, less soft tissue stripping than with direct lateral approach, preserves periosteal blood supply to fracture, lateral incision in line with femoral shaft, elevate vastus lateralis from ITB fascia and posterior septum, place chandler over anterior cortex to expose lateral femur, reduce fracture with traction and reduction forceps, can place interfragmentary screw for simple fracture patterns, comminuted fractures will require bridge plate, priority goes to fixing femoral neck because anatomic reduction is necessary to avoid complications of AVN and nonunion, screws for neck with retrograde nail for shaft, compression hip screw for neck with retrograde nail for shaft, single constuct fixation is associated with femoral neck fracture displacement and loss of reduction, antegrade nail with screws anterior to nail, usually done if neck fracture is identified after the femoral shaft fracture has been addressed, 10% when using fracture table with traction, femoral artery is medial to femur if proximal locking screw is placed proximal to lesser trochanter in retrograde nails, can occur when inserting proximal interlocking screws during a retrograde nail, most accurately determined by the Jeanmart method, angle between a line drawn tangential to the femoral condyles and a line drawn through the axis of the femoral neck, anterversion and external rotation are positive values for equation, retroversion and internal rotation are negative values for equation, up to 15 degrees is usually well tolerated, use of a fracture table increases risk of, if noticed intraoperatively, remove distal interlocking screws and manually correct rotation, if noticed after union, osteotomy is required, dynamization of nail with or without bone grafting, incomplete healing within 9 months of injury or no evidence of healing on successive radiographs over 3 months, postoperative use of nonsteroidal anti-inflammatory drugs, smoking is known to decrease bone healing in reamed antegrade exchange nailing for atrophic non-unions, broken distal interlock screws can be seen on radiographs, race between healing and implant failure is lost, distal interlock screws are exposed to the greatest stresses, results in fracture of the interlock screw in the region inside the nail, works by increasing construct stiffness, enhanced isthmic fit, and extrusion of reaming contents to nonunion site, some studies have demonstrated higher union rates than exchange nailing, external fixation used if fracture not healed, quadriceps and hip abductors are expected to be weaker than contralateral side, antegrade starting point 6mm or more anterior to the intramedullary axis, however, anterior starting point improves position of screws into femoral head, increased cortical hoop stresses with anterior starting points, using an anterior start point for a piriformis nail can result in a proximal femur fracture, failure to overream canal by at least .5 mm, lengthening along the anatomical axis of the femur leads to lateral MAD, shortening along the anatomical axis of the femur leads to medial MAD, due to mismatch of the radius of curvature of the nail to the radius of curvature of the femur, average radius of curvature of human femur is 120 +/- 36 cm, starting points that are too posterior (especially piriformis start points) with relatively straight nails, Proximal Humerus Fracture Nonunion and Malunion,
