Introduction/Objective. Subtrochanteric fractures are unstable, tending to a varus, antecurvatum, and shortening deformity. The aim of this paper was to compare operation time and fluoroscopy time between different internal fixation methods in the treatment of subtrochanteric fractures. Method. The prospective study of the group of 27 patients with a subtrochanteric fracture treated by the SIF (selfdynamisable internal fixator with a trochanteric unit) method had been done. Operation time and fluoroscopy time values from this group were compared to the same parameters data from the literature for intramedullary (IM) nails, proximal femur locking plates (PF-LCP), dynamic condylar screws (DCS), and the 95?-angled blade plate. Results. In the SIF group, operation time was 62.2 (25?140) minutes and fluoroscopy time was 43 (20?95) s. Average operation time from the literature data was: 102.1 (43?181) minutes for IM nail, 94.2 (75?129) minutes for PF-LCP, 105.3 (70?166) minutes for DCS and 221.5 (171?272) minutes for blade plate. Average fluoroscopy time from the literature data was: 109.6 (34?250) seconds for IM nail, 102.3 (47?180) seconds for PF-LCP, 238 seconds for DCS. Operation time and intraoperative fluoroscopy time were higher in IM nail, PF-LCP, DCS and blade plate comparing to SIF method (p < 0.05). Conclusion. The above mentioned difference could be explained by a degree of required accuracy in the initial operative technique maneuvers, by used number of screws and by the type of the fracture reduction performance in different fixation methods. Operation time during IM nailing of subtrochanteric fractures sometimes can be shorter than average operation time in SIF method, what could be explained by the skill of the surgeon to perform as fast closed reduction for insertion of guide wire.

Abstract Background: Intraoperative technical complications are occasionally encountered while implanting intramedullary nails for subtrochanteric fractures. Surgeons must pay attention to the pitfalls and remedial technique of this operation.Methods: We report on three cases in which intraoperative difficulties occurred during the implantation of an intramedullary nail among Han Chinese patients from mainland China. In Case 1, during an operation on a 57-year-old man, a seinsheimer type V in a right subtrochanteric fracture was not fully realized, and the dislocation of intertrochanteric fracture was aggravated after reduction of the subtrochanteric fracture. The intramedullary nail fixation was completed with the aid of an additional anterolateral plate. Case 2 involved a transverse subtrochanteric fracture. The surgeon neglected the coronal dislocation when considering good sagittal reduction. Although an auxiliary reduction device was used during the operation, there was unacceptable coronal dislocation after the intramedullary nail was inserted. A temporary anterolateral locking plate fixation was used to complete the intramedullary nail fixation. Case 3 involved an old trochanteric fracture combined with a new subtrochanteric fracture in an 81-year-old woman. After reducing the subtrochanteric fractures, the intramedullary nail fixation was successfully completed by releasing the poorly healed intertrochanteric fractures and fixing the anterior lateral plate.Results: With the development of techniques, reliable results can be obtained with fewer complications. Of the various internal fixation methods, we favor using a trochanteric start intramedullary nail.Conclusions: The treatment of subtrochanteric fractures presents challenges. Good reduction and reliable temporary fixation are key to completing the intramedullary nailing. If percutaneous joysticks, finger reduction tools, blocking screws, clamps, and Schanz pins cannot be used for effective auxiliary reduction or temporary reliable fixation, reduction after intramedullary nailing will not be satisfactory. The temporary addition of a reconstruction locking plate can achieve good reduction and temporary stability, and an extra reconstruction locking plate should be retained when the temporary fixation device is removed to reduce the risk of internal fixation failure during fracture healing.

Osteoporosis is a type of systemic bone disease wherein the patient is highly vulnerable to bone fracture because of the decrease in bone density and quality, destruction of the bone microstructure, and an increase in the bone fragility. Most of the osteoporotic subtrochanteric fractures are unstable in nature, requiring the conservative treatment of a long-duration bed rest and traction; this condition is prone to complications resultant from extended bed rest, often leading to death. Presently, the preferred treatment is internal fixation, such as sliding hip screws, blade plates, locking compression plates, and femoral intramedullary nails [1-8]. Owing to its valuable biological properties, intramedullary nail can be used for the optimal fixation of subtrochanteric fractures [9-11]. Unless any contraindication exist, immediate tolerable weight-bearing activities may be allowed to patients with subtrochanteric femur fractures who have been treated with statically locked intramedullary nails [12]. Considering that the proximal femoral fracture occurs under the traction of the surrounding muscles, it is extremely challenging to perform precision reduction and fixation in the surgery. Inappropriate reduction and selection of internal fixation can easily lead to failure of internal fixation, resulting in complications such as lower limb shortening deformity, hip varus deformity, and nonunion of fracture. Presently, good outcomes have been reported with the use of PFNA combined with cerclage wire for the treatment of subtrochanteric fracture of the femur [13-15]. There are few studies to help decide whether PFNA should be combined with cerclage wire or used alone according the Seinsheimer classification of subtrochanteric fractures.

SUMMARY OBJECTIVE To compare the effect of two internal fixation methods in the treatment of proximal clavicle fractures. METHODS Fifty patients with proximal clavicle fractures received surgical treatment. They were divided into a clavicular T-plate group and a double mini-plates group. The duration of the operation, blood loss during the operation, fracture healing time, and incision infection were evaluated between the two groups. RESULTS Operation time (t=2.063, P=0.058), intraoperative bleeding (t=1.979, P=0.062), and fracture healing time (t=1.082, P=0.066) were not statistically significant in the two groups. The patients were followed up for 12-18 months; one patient in the T-plate group had early removal of nails, but no clinical symptoms. At the 2-month follow-up, the ASES score in the double mini-plates group was significantly better than in the T-plate group (P<0.001); but at the 6-month follow-up, 1-week before removal of internal fixation and the final follow-up, the two groups had no significant differences (P>0.05). CONCLUSIONS Both internal fixations have similar clinical results in the duration of operation, blood loss during the operation, and fracture healing time. The double mini-plates fixation presents advantages by reducing complications and speeding fracture healing; thus it is a more effective method to treat proximal clavicle fractures.

Background This study aimed to evaluate a personalized 3D-printed percutaneous vertebroplasty positioning module and navigation template based on preoperative CT scan data that was designed to treat patients with vertebral compression fractures caused by osteoporosis. Methods A total of 22 patients with vertebral compression fractures admitted to our hospital were included in the study. Positioning was performed with the new 3D-printed positioning module, and the navigation template was used for patients in the experimental group, and the traditional perspective method was used for patients in the control group. The experimental group consisted of 11 patients, 2 males and 9 females, with a mean age of 67.27 ± 11.86 years (range: 48 to 80 years), and the control group consisted of 11 patients, 3 males and 8 females, with a mean age of 74.27 ± 7.24 years (range: 63 to 89 years). The puncture positioning duration, number of intraoperative fluoroscopy sessions, and preoperative and postoperative visual analog scale (VAS) scores were statistically analyzed in both groups. Results The experimental group had shorter puncture positioning durations and fewer intraoperative fluoroscopy sessions than the control group, and the differences were statistically significant (P < .05). There were no significant differences in age or preoperative or postoperative VAS scores between the two groups (P > .05). Conclusions The new 3D-printed vertebroplasty positioning module and navigation template shortened the operation time and reduced the number of intraoperative fluoroscopy sessions. It also reduced the difficulty in performing percutaneous vertebroplasty and influenced the learning curve of senior doctors learning this operation to a certain degree.

The Impact

Iatrogenic subtrochanteric fractures are rarely encountered after cannulated screw fixation of femoral neck fractures; however, when they do occur, there can be several complications. Many orthopedic surgeons have concerns about the potential for iatrogenic subtrochanteric fractures after screw fixation distal to the trochanter minor; therefore, some surgeons are typically reluctant to perform this procedure. This study focused on the risk of an iatrogenic subtrochanteric fracture after treating femoral neck fractures with cannulated screws. The main purpose of the study was to understand iatrogenic subtrochanteric fractures and evaluate the effects on these fractures of an inverted triangular–shaped configuration for placement of the cannulated screws. A femur bone with an femoral neck fracture at a 40° incline to the horizontal plane was generated along with a representation of a three-dimensional finite element model, and three inverted triangular–shaped configurations for placement of the cannulated screws were investigated using finite element analyses. Statistical results indicated that the occurrence risk of ISF increases when the screw is located distal to the trochanter minor. Moreover, the risk of occurrence of intertrochanteric fracture increases when the screw is located medial to the trochanter minor because of local concentrated stress on the surface of the screw canals. To avoid the vulnerability of the subtrochanteric region, it was found that proximal placement of the screws using the inverted triangular–shaped configuration could yield better results. In addition, the results of this study provide suggestions on improved screw configurations.

Abstract Background: Traditional methods for minimally invasive internal fixation (MIIF) of calcaneal fractures require extensive intraoperative fluoroscopy, and fracture recovery is usually not ideal. We developed a new surgical procedure using digital surgical simulation and constructed a patient-specific instrument (PSI) for calcaneal fracture that we used during the operation. This study investigated whether PSI-assisted MIIF of calcaneal fracture enables rapid and accurate execution of the preoperative plan.Methods: We retrospectively analyzed patients with Sanders type III or IV fresh calcaneal fractures who had undergone PSI-assisted MIIF at our hospital from January 2016 to December 2018. We analyzed perioperative data including intraoperative fluoroscopy time, concurrence of internal fixation actual usage (IFAU) with the preoperative plan, surgery time, and complications. We also compared pre- and postoperative actual measurements from X-ray radiographs and computed tomography images including Böhler, Gissane, and calcaneus valgus angles; subtalar joint width; and calcaneal volume overlap ratio with the preoperative design. All patients had been followed up and their American Orthopedic Foot and Ankle Score (AOFAS) score was available.Results: Mean intraoperative fluoroscopy time was 3.95±1.78 h; IFAU in 16 patients (16 feet) was the same as the preoperative plan; mean surgery time was 28.16±10.70 min; and none of the patients developed complications. Böhler, Gissane, and calcaneus valgus angles and subtalar joint width did not differ between pre- and postoperative plans; however, the actual preoperative values of each of these parameters differed significantly from those measured postoperatively. The calcaneal volume overlap ratio with the preoperative design was 91.2%±2.3%. AOFAS scores increased with time, with significant differences in the score at each time point.Conclusions: The newly developed PSI-assisted calcaneal fracture MIIF method can rapidly and accurately execute the preoperative plan.

Objective. To analyze the effect of PFNA-II internal fixation on hip joint recovery and quality of life (QOL) in patients with lateral-wall dangerous type of intertrochanteric fracture. Methods. One hundred and twelve patients with lateral-wall dangerous type of intertrochanteric fracture who underwent surgical treatment in our hospital from May 2017 to May 2019 were selected as the participants of the study. Based on the treatment method, all the enrolled patients were divided into two groups: proximal femoral nail antirotation (PFNA group; n = 59 ) who received closed reduction and minimally invasive PFNA internal fixation and dynamic hip screw group (DHS; n = 53 ) who received internal fixation. The clinical indicators, curative effect, hip function score, pain degree, postoperative QOL score, and complications were compared between the two groups. Results. The operation time, intraoperative blood loss, postoperative drainage volume, and the incidence of postoperative complications in PFNA group were statistically lower than those in DHS group ( P < 0.05 ). The curative effect in PFNA group was notably better than that in DHS group. There were no significant differences in scores of hip function, visual analogue scale (VAS), and QOL between the two groups before operation ( P > 0.05 ). However, the hip function score and QOL score increased in both groups after surgery, and the increase was more significant in the PFNA group, while the VAS score decreased in both groups, and the decrease in PFNA group was more significant ( P < 0.05 ). Conclusion. PFNA internal fixation for the treatment of lateral-wall dangerous type of intertrochanteric fracture has the advantages of short operation time, less intraoperative blood loss, effective improvement of hip joint function, and fewer postoperative complications, which is worthy of clinical application.
