Objective:To study the treatment of results of the fracture of the shaft of the tibia treated with tibia locked inner marrow nail.Methods:Forty-five patients with the fracture of the shaft of the tibia with the tibia locked inner marrow nail were viewed,forty were followed up.The results were evaluated based on clinical and radiographic parameters.The duration of following up ranged from six months to twenty-four,with an average of eighteen months.Results:Forty patients were evaluated as having excellent result,three patients were good.The excellent or good rate was 95.6%.Concluson:The treatment of the fracture of the shaft of the tibia with locked inner marrow nail should have the advantages of simple manipulations,less trauma and good results,and might be worthy of popularization.

ABSTRACT A tibial shaft fracture model was created to study the effects of an intramedullary nail and partial fibulectomy on fracture loading. Cadaveric lower extremities were instrumented with strain gages and subjected to biomechanical testing. A nonreamed nail was inserted into each tibia using only the proximal locking screws. Each specimen was tested under six conditions: intact tibia; intact tibia with nail; fractured tibia with nail removed and fibula intact; fractured tibia with nail and fibula intact; fractured tibia with nail and partial fibulectomy; and fractured tibia with partial fibulectomy and nail removed. In the intact tibia the anterior cortices were in relative tension compared with the posterior cortex. After transverse fracture this relative tension was increased. Inserting the nail after fracture significantly increased anteromedial and anterolateral compressive strains and decreased posterior strains. Performing a partial fibulectomy in the fractured tibia with a nail had no significant effect on the strain patterns. These results confirm the relative anterior tension present in the intact tibia and demonstrate an increase in this anterior tension following transverse fracture. Performing a partial fibulectomy or inserting an intramedullary nail increased anterior compressive loading. This loading alteration may be responsible for the clinical success seen using these treatment methods.

Aim: Through the biomechanical analysis andclinically retrospective follow-up of the patients treated ei-ther by unreamed inter-locking intramedullary nail of tibiaor rotating external fixator of tibia, the authors aimed atcomparing their biomechanical properties and the options ofclinical indications. Methods: An unstable fracture modelwas developed in 10 cadaver tibias in which either unreamedinterlocking intramedullary nail of tibia or rotating externalfixator of tibia was applied randomly to fix the models. Themodels were then tested on the WJ-10A Universal TestingSystem. A total of 44 tibia fractures treated by both deviceswere followed up with an average duration of 13 months.Results: The maximum loading to failure (MLF) of fixatorgroup was 2130 N, while that of nail group was 2275 N,and no significant differences were found between themthrough test (P 0. 05 ). The clinical follow-up revealedthat the significant differences really existed between themin terms of operating time, X-ray exposure time as well asintraoperative blood transfusions (P0.01), while no sig-nificant differences were found in terms of bone healingtime, weight bearing time and knee-ankle joint function.Conclusion: Both devices are considered much more effective in the treatment of tibia fracture. The unreamed inter-locking intramedullary nail of tibia should be the first choiceof the treatment of non-union and malunion of tibia fractures.

Objective To investigate the curative effects of the intramedullary expanded self locking nail(IESN) on the multiple tibia shaft fractures.Methods Thirty one cases of multiple tibia shaft fractures were treated with the IESN.Of these 31 cases,27 fractures were fresh(9 were exoteric).The remaining 4 were old fractures that were treated with autoglogous bones transplantations.Results After 8 to 22 months' follow up,all the fractures were in union.The overall excellent rate is 96.7%.Conclusion IESN has the virtues of slight trauma in operation.In the inner fixation therapies of the multiple tibia fractures,it can preferably maintain the fracture part's biology surroundings.It is quite a perfect therapy for the multiple tibia fractures.

Objective To investigate the clinical curative effect of treating tibia fracture by minimally invasive percutaneous plate osteosynthesis(MIPPO). Methods Fifty-seven cases of tibia fracture which were divided into the MIPPO group and the interlocking intramedullary nail group randomly were treated with two kinds of internal fixations. The data of Fifty-seven patients were analyzed retrospectively, and patients’general state during and after the operation was compared. All the patients were followed up for 12-30 months after operation (average 16 months). Five factors including surgery time, intraoperation bleeding, inhospital time, healing time and complications were studied statisfically to analyse the two kinds of internal fracture fixations. Results Treatment of tibia fracture with MIPPO was as good as interlocking intramedullary nail. There was no significant difference between two groups in surgery time, intraoperation bleeding, inhospital time, healing time and complications. Conclusion The two therapies both can reduce disturbing vascularization of bone fragment, accelerate bone healing and reduce complications.The interlocking intramedullary nail should be the first choice for tibia shaft and malunion of tibia fracture as well as MIPPO for tibia shaft and distal tibia metaphyseal fractures.

Background: Fracture of the tibia shaft accounts for 17% of lower extremity fractures, with concurrent fibula fracture in about 78% of these cases. Intramedullary fixation for fibula fractures can restore fibula alignment and thus facilitate fracture reduction, especially in cases with comminuted shaft or distal metaphyseal tibia fractures. Methods: Patients who had internal fixation of comminuted tibia shaft or distal metaphyseal tibia fracture and a concurrent fibular fracture treated with intramedullary Steinman pin fixation were included in this study. Patients' demographic data and fracture patterns were analyzed retrospectively. Postoperative X-rays were used for fracture union evaluation and alignment analysis. Results: Nine males and one female were included in the present study. Tibia fractures were classified as four OTA42 and as six OTA43, including one type I, two type II, one type IIIA, and three type IIIB open fractures. Intramedullary nail and locking plate were used as definitive fixation in four and six cases, respectively. Complications required additional surgeries including wound debridement for one patient, bone graft for three patients, and revision surgery from a broken plate to an intramedullary nail for one patient. A total of 14 fibula fractures were identified in ten patients due to four segmental fractures. Eight were Weber type C, one was Weber type B, and five were midshaft fractures. The mean duration of fibula fracture healing according to radiographs was 6.9 months. Conclusions: This study suggests that intramedullary Steinmann pin fixation for concurrent fibula fracture is a critical procedure when dealing with comminuted shaft or distal metaphyseal tibia fractures.

The Resonant Frequency (RF) of the tibia is proportional to its stiffness. As a fractured tibia heals, its RF should increase. The RF was serially determined in 74 fractured tibias (205 examinations). These were subdivided by fracture location and fixation. Fast Fourier transform software generates the RF from data obtained with an instrumented impactor and accelerometer. The RF was normalized by expressing it as a ratio of the intact tibia. This ratio is called the tibial stiffness index (TSI). A 20 point tibial fracture score (TFS) quantitated the clinical and radiographic signs of healing. For each group the paired TSI and TFS were compared by regression analysis. Except for those fractures limited to the proximal fourth of the tibia, the TSI was found to correlate significantly (p = 0.0001) with the TFS. Fractures without fixation and those with unlocked, unreamed tibial nails showed very significant correlation of TSI with TFS (p = 0.0001). RF analysis was not useful in fractures with locked or reamed tibial nails. Examination of tibia with external fixation showed significant correlation (p = 0.02) of the TSI with the TFS.
