50 cases of bone mechanical strength of hip fracture prognosis


Xiao-Dong Liu Shun-Lin Chen Tailin ', a R a f, f clinical data of the group of 50 down, down male 31, female 19 down; younger than 13 years of age j0 down, 50 to 70 years old 27 down, 10 more than 70 years of age down, the biggest causes of injury l back 92 years: traffic accident in 38, falls accounted for 32, fall injuries account for l2,[link widoczny dla zalogowanych], other injuries accounted for 18 made according to Singh in 1978, X-ray measurement of bone forms a small beam to measure the mechanical strength of bone 6 method (WANG Yi held editor. Bone and joint injuries. Beijing: People's Medical Publishing House, 1992,587.) were measured bone mechanical strength of this group of patients 6, 16, accounting for 32, its not in dispute He 50 years old; 5, 13, accounting for 26, aged 40 to 50 years old I per I; 4 grade l5, accounting for 30, older than 50 years of age; 3, 6, accounting for all ages are large l2 in 70 years. Rejection adopted for internal fixation surgery: double screw fixation in 5 cases, more than l0 nail down, wings fixed plus fine feed Jair nail l6, Richard nailing 14 down, 5 cases of femoral head replacement and internal fixation are essential to achieve Clinical follow-up anatomic: Where the original bone mechanical strength greater than or equal to 4 were excellent effect, and the original bone mechanical strength 3 below less effective. Followed up more than 1 year, 30 where, more than 6 October, adding up to 1-year fall, l0 patients who had reached on October 6, according to Huang Gongyi and other criteria (Spine, 1984,4 t349): 76% excellent, good l6%, difference 8 2. feeding delayed infection occurred in 1 case failed femoral head rotation deformity (preoperative bone mechanical strength in the 3 ~ 4 Q) with mild coxa vara secondary l0 feed (preoperative bone mechanical strength and more in the 4 below) to discuss (1j previous years, and this set of data reports are confirmed, fractures and bone mechanical strength after the gourd was proportional to the use of inverted relations have now reached by a fixed rigid fixation material requirements, but only to withstand the stress within the implant 25, Another 75 from the bone itself under gung IJ. fractures and injuries by type of cable than on, the more units and bone mechanical strength of the night 2241O0 Dafeng, Jiangsu Branch degrees on public health carpal bone strength of the lower machine maple, Moments after injury, driving bone fractures and neck,[link widoczny dla zalogowanych], or trochanter lesser trochanter bone behind the occurrence of varus collapse is almost inevitable at the same time prone to internal fixation bone slip, so that long-term effect of significantly reduced. Upon a sick group , F, 77 years old, mechanical strength of left femoral neck fractures with grade 3, multiple screw fixation, nonunion after, diverted to artificial femoral head replacement, holding off because of osteoporosis and the rotary bit sink only to head out , surgical failure, confirmed the mechanical strength of bone has a direct impact on the prognosis. (2) cured in the choice of surgical side, should take into account these fractures were mostly the elderly, bone mechanical strength is generally low, due to claims should be based on a variety of better choice for simple ways to those of bone mechanical strength is still high, calcar,[link widoczny dla zalogowanych], small trochanteric bone integrity that due to relatively stable after surgery, the choice of multi-fixation, the plane hurt small, fixed effect has been to meet the needs of those low mechanical strength of bone. femoral moment, lesser trochanter were fractures, bone behind the collapse, the more the use nails or winged fine Richard dynamic hip screw,[link widoczny dla zalogowanych], such fixed strong, can make up bone lower mechanical strength of the defect, is conducive to reducing the incidence of complications of hip varus. Also note that the lag screw in the pre-position, as far as possible through the Word of low and intraoperative's triangle anatomic reduction as possible, because the anatomical has a good anti-shift capability (3) there are indications of bone mechanical strength in the four above-level fixation success rate was 80,3 compared to 2o below also show that this set of data common complication after bone mechanical strength, varus deformity, such as hip joint and bone fork there is a very close relationship. Therefore, in clinical practice, according to the prognosis of bone mechanical strength (including bone healing and functional recovery) make estimates of the operative procedures and clinical drug treatment ( Orange osteoporosis treatment) plays an important reference and guide.
