Background technology
Intertrochanteric fracture is a kind of clinically common fracture, with the development and the aging of population of social economy, slightly
The complexity of the grand incidence of disease fractured and classification of fracture, into trend is gradually increasing, is the patient's early ambulation realized,
The complication of malunion and the elderly's long-term bed is avoided, internal fixation operation treatment has become the first-selection of the type fractures
Therapeutic modality, the key point of internal fixation operation treatment is the quality of reduction of fracture, and good reset can make to be obtained between sclerite
Excellent support, and then compression and shearing force that internal fixation material bears are reduced, improve the success rate of operation, it is to avoid fracture is moved again
Position and interior fixation cut out from femoral head and postoperative occur moving back the complication such as nail.Minimally invasive intramedullary nail treatment intertrochanteric fracture into
It is the developing direction of intertrochanteric fracture operative treatment, and has clinically been used widely, but how is not increasing soft
The anatomical reduction that fracture can be reached on the premise of tissue injury again is always focus and problem clinically.
Three problems for clinically mainly being faced using intramedullary nail treatment intertrochanteric fracture at present are as follows:

Line perspective can also be damaged to medical worker and patient.And part is difficult to the fracture for resetting, open reduction is needed, this can increase wound
Bleeding is injured, causes the probability of postoperative fracture disunion to increase.
2nd, for serious fracture patient, the soft tissue set destruction of surrounding of fracturing is heavier, and the sclerite for having resetted is in hand
Easily occur resetting in art operation losing:More serious due to fracturing in complicated intertrochanteric fracture, fragmentation is multiple between tuberosity
Sclerite, lacks soft group of good link between sclerite, while fracture often adds up entry point, during marrow is expanded in main nail opening
Because opener or start bit are relatively large in diameter, opener or drill bit along guide pin in pulp cavity progradation to the bone piece shape of surrounding
Into peripherad extruding, particularly when fracture line adds up entry point, drill bit enters pulp cavity from fracture line, because drill bit is to surrounding
The extruding of bone piece, and then the reset of sclerite occur and lose again and significantly shift again, particularly bigelow's septum reset are lost again,
Bigelow's septum is the basal seat area of region compression between tuberosity, the malreduction in this region, it is easy to cause coxa vara, early loading
There is interior fixed cutting out and enters articular cavity in patient, increases the mortality performed the operation and the amount of bleeding for increasing postoperative pulp cavity.
3rd, often occurs the loss for resetting in art due to the deviation for operating in Fracture Simple:Due to inserting the process of guide pin
In be operative doctor and be implanted into manually, it is difficult to the axis after axis and the intramedullary nail implantation of the guide pin that ensures to perform the operation every time is weighed completely
It is folded, therefore exist between the normal position that should locate after the cavity and intramedullary nail entrance for expanding along guide pin and being formed after marrow is likely to occur in art
Certain deviation, after the main nail of intramedullary nail is inserted, main nail near-end will be formed to sclerite and extruded, and then fracture block reset occurs
