ABSTRACT

OBJECTIVE@#To summarize the complications of core drilling intramedullary nail in the treatment of femoral shaft closed fracture and explore the treatment strategy.@*METHODS@#From August 2014 to June 2018, a total of 215 patients with closed femoral shaft fractures were treated with closed reduction core drill intramedullary nail, including 129 males and 86 females, aged from 18 to 62 years, with an average of (44.2±10.6) years old. The time from injury to operation was 3 to 21 days. There were 102 cases of AO type A fracture, 82 cases of AO type B fracture and 31 cases of AO type C fracture. The time of operation, the amount of blood loss during operation, the duration of hospitalization, the time of fracture healing and the HSS score of knee joint function at the last follow-up were recorded. The observation of complications included:iatrogenic fracture, core drill broken, core drill twist, postoperative infection, and fracture nonunion.@*RESULTS@#The average operation time was (63.2± 15.6) min and intraoperative blood loss was (150.0±34.5) ml. All the incisions reached grade A healing. Patients were follow up for a mean of (18.5±3.2) months, the average hospital stay was (4.3±1.2) days, and the average fracture healing time was (5.6±2.3) months. At the final follow-up, the average HSS score of knee joint was 90.3±4.7. Related complications occurred in 37 cases (17.2%). The core drill related complications occurred in 13 cases (6.0%), including core drill broken in 5 cases (2.3%), core removal in 1 case and slotting in 4 cases;core drill twist in 8 cases (3.7%). After the core was cut, the core was removed. Similar complicationsof conventional intramedullary nail:iatrogenic fracture was performed in 12 cases (5.6%), including 10 cases of fracture end split and 2 cases of distal perimedullary fracture of intramedullary nail. The patients with cleavage at the fracture end were not treated after judging their stability, and the patients with fracture around the distal end of the intramedullary nail were fixed with auxiliary steel plate during operation;1 case(0.4%) with delayed infection after operation, debridement and external fixation was replaced and healed after bone transfer; fracture nonunion occurred in 11 cases (5.1%), of which 7 cases (3.3%) were hypertrophic nonunion and healed with additional plate. Atrophic nonunion occurred in 4 cases (1.9%), which healed after additional steel plate and bone graft.@*CONCLUSION@#Core drilling intramedullary nail is an effective method for the treatment of closed femoral shaft fracture, and the complications include core drill related complications and conventional intramedullary nail similar complications. Accurate preoperative evaluation, careful operation during operation and early postoperative symptomatic treatment can effectively reduce the occurrence of related complications.

ABSTRACT

<p><b>OBJECTIVE</b>To compare the clinical effects of three methods of internal fixations in treating intertrochanteric fractures in elderly patients.</p><p><b>METHODS</b>From 2004 to 2008, the clinical data of 112 patients with intertrochanteric fractures were retrospectively analyzed. There were 63 males and 49 females, aged from 60 to 80 years with an average of 66.2 years. The patients were treated respectively with dynamic hip screws (DHS group, 40 cases), anatomic plate (anatomic plate group, 36 cases) and proximal femoral intramedullary nails (PFN group, 36 cases). The data of each group were collected for statistical analysis on the following aspects: operative time, blood loss volume, clinical healing time of fracture, postoperative complications, and hip functional score of Harris.</p><p><b>RESULTS</b>All these patients were followed up from 20 to 24 months with an average of 22.6 months. There was no significant difference in operative time, blood loss volume among three groups; there was significant difference in clinical healing time of fracture, Harris score and postoperative complications among three groups (P < 0.05). In the healing time, the PFN group was significantly less than that of other groups (P = 0.001), but there was no differences between DHS group and anatomic plate group. In the Harris score, the PFN group was significantly higher than that of other groups (P = 0.001), but there was no differences between DHS group and anatomic plate group. In the aspect of postoperation complication, there was 2 cases of coxa vara, 1 case of internal fixation loosening and 1 case of deep venous thrombosis in the DHS group; there were 2 cases of deep venous thrombosis in the PFN group; there were 2 cases of coxa vara and 1 case of internal fixation loosening in the anatomic plate group (P = 0.001).</p><p><b>CONCLUSION</b>In the treatment of intertronchanteric fractures, proximal femoral intramedullary nail may be the best choice, which can decrease healing time as well as complications postoperatively.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the feasibility and safety of the treatment for thoracolumbar fractures with transpedicular intracorporeal hydroxyapatite grafting and pedicle screw fixation via paraspinal approach.</p><p><b>METHODS</b>From June 2007 to December 2008, 19 cases of thoracolumbar fractures were treated with transpedicular intracorporeal hydroxyapatite grafting and pedicle screw fixation via paraspinal approach. There were 7 female and 12 male, ranging from 21 to 57 years of age (mean 40.8 years) at surgery. The time from injury to surgery varied from 1 d to 5 d (mean 2.9 d). Nineteen patients all suffered from single thoracolumbar fracture with the distribution of injury level being T(11) in 1, T(12) in 5, L(1) in 9, and L(2) in 4. According to Denis fracture classification, there were 5 compression fractures and 14 burst fractures. The mean preoperative ratio of the anterior height of the body was 57.2%, kyphosis angle was 17.6° and occupation of spinal canal was 27.7%. The mean preoperative load-sharing classification of spine fractures was 5.2. Based on the ASIA neurologic grading system, preoperative neurological function was grade B in 2 cases, C in 9 and D in 8.</p><p><b>RESULTS</b>Median operating time was 83.8 min (range 60-95 min) and median blood loss was 133 ml (range 90 - 200 ml). Infection did not occur in any of the patients and the operative incisions were healing well. Average follow-up time was 19.2 months (range 12 - 36 months). At the latest follow-up, the height of the anterior border was corrected to 88.4%, the kyphosis angle was 6.1°, and the occupation of spinal canal was 8.2% on average. The postoperative neurologic function of all 19 patients was improved with grade D in 2 cases and E in 17. There were no instances of instrumentation failure and no patient had persistent postoperative back pain.</p><p><b>CONCLUSIONS</b>Transpedicular intracorporeal hydroxyapatite grafting and pedicle screw fixation via paraspinal approach could provide reliable neurologic improvement in patients with incomplete neurologic deficit, and could prevent the development of kyphosis.Furthermore, it has the obvious advantages of less invasive and blood loss, and decreases the risks of postoperative lumbodorsal pain.</p>

ABSTRACT

Comminuted fracture of distal femur is a common lower limb injury from traffic accidents, especially from motor accidents. Routine dynamic condylar screw (DCS) or 95-degree condylar plate (CP) sometimes cannot solve the bone defect in the center of alignment and contralateral diaphysis for the reason of absent screw anchor point, especially for AO C2.2-2.3 types. Many authors recommended open reduction and fixation with less invasive stabilization system (LISS) as the treatment of choice, but there are still problems in fusion and alignment. In this study, we reported our experiences with the use of bone splint technique in the high-energy commimuted fracture of distal femur with central and medial bone defect in adolescents.

ABSTRACT

<p><b>OBJECTIVE</b>To develop an epiphyseal slide-traction plate in child, which can supply the fracture a sufficient internal fixation, and will not restrain the growth of epiphyses. Animal experiments were carried out with the plates to compare the slide-traction with traditional plate.</p><p><b>METHODS</b>Develop a slide-traction plate for the configuration of the femur condylus of children. Thirty adolescent goats in the experiment were divided into control group (12 goats) and plate group (18 goats). In plate group, right femurs of goats were fixed with common plates and the left femurs with slide-traction plates. All the goats were given X-ray examination at different time after surgery. And the goats were sacrificed at 3 and 6 month, histological method and electron microscopy were performed to evaluate the development of epiphyseal plate.</p><p><b>RESULTS</b>The both femurs of the goats in control group have no difference in evidence in length at all time we examined. And the both femurs of the goats fixed with plates have no difference in evidence in length at 1 day after surgery. However, the both femurs of the goats fixed with plates have difference in evidence in length at 1 month, 2 month, 3 month, 6 month after surgery. The increased length of the femurs at I month, 2 month, 3 month, 6 month after surgery was also compared with the length at 1 day after surgery, there was difference in evidence between the right femurs of the control group and the femurs were fixed with common plates, but no difference in evidence between the left femurs of the normal control group and the femurs were fixed with slide-traction plate (P > 0.05). More thicker epiphyseal plate were found in the left femurs than the right femurs of the group fixed with plates at 3 and 6 month after surgery (P < 0.01). In the plate group, safranine O staining showed epiphyseal plates at the left femurs had more fuscous staining than the right femurs at 3 and 6 month after surgery and electron microscopy also found that the cells of the epiphyseal plates of left femurs were more eugenic than the right femurs at 3 and 6 month after surgery.</p><p><b>CONCLUSION</b>The epiphyseal slide-traction plate can slide with the growth of epiphyses, which is suitable for fixation of the fracture in this part.</p>
