Management of infected bone defects of the femoral shaft by Masquelet technique: sequential internal fixation and nail with plate augmentation. BMC Musculoskelet Disord 2024; 25:552. [PMID: 39014409 PMCID: PMC11253414 DOI: 10.1186/s12891-024-07681-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/12/2024] [Accepted: 07/09/2024] [Indexed: 07/18/2024] Open
Abstract
BACKGROUND To evaluate the effectiveness of a sequential internal fixation strategy and intramedullary nailing with plate augmentation (IMN/PA) for bone reconstruction in the management of infected femoral shaft defects using the Masquelet technique. METHODS We performed a retrospective descriptive cohort study of 21 patients (mean age, 36.4 years) with infected bone defects of the femoral shaft treated by the Masquelet technique with a minimum follow-up of 18 months after second stage. After aggressive debridement, temporary stabilisation (T1) was achieved by an antibiotic-loaded bone cement spacer and internal fixation with a bone cement-coated locking plate. At second stage (T2), the spacer and the locking plate were removed following re-debridement, and IMN/PA was used as definitive fixation together with bone grafting. We evaluated the following clinical outcomes: infection recurrence, bone union time, complications, and the affected limb's knee joint function. RESULTS The median and quartiles of bone defect length was 7 (4.75-9.5) cm. Four patients required iterative debridement for infection recurrence after T1. The median of interval between T1 and T2 was 10 (9-19) weeks. At a median follow-up of 22 (20-27.5) months, none of the patients experienced recurrence of infection. Bone union was achieved at 7 (6-8.5) months in all patients, with one patient experiencing delayed union at the distal end of bone defect due to screws loosening. At the last follow-up, the median of flexion ROM of the knee joint was 120 (105-120.0)°. CONCLUSIONS For infected femoral shaft bone defects treated by the Masquelet technique, sequential internal fixation and IMN/PA for the reconstruction can provide excellent mechanical stability, which is beneficial for early functional exercise and bone union, and does not increase the rate of infection recurrence.

Abstract
BACKGROUND Limited information exists on nonunion treatment in the elderly. This retrospective study evaluates whether results of operative treatment of nonunion of the humerus or femur in patients aged ≥ 75 years are comparable to those in younger patients. METHODS We identified patients age ≥ 75 years with a nonunion of humerus or femur treated with open reduction and internal fixation. The Non-Union Scoring System was calculated. Complications, clinical outcome, and radiographic findings were assessed. Primary endpoint was nonunion healing. A literature review compared time to healing of humeral and femoral nonunion in younger populations. RESULTS We identified 45 patients treated for a nonunion of humerus or femur with > 12 months follow-up. Median age was 79 years (range 75-96). Median time to presentation was 12 months (range 4-127) after injury, median number of prior surgeries was 1 (range 0-4). Union rate was 100%, with median time to union 6 months (range 2-42). Six patients underwent revision for persistent nonunion and healed without further complications. CONCLUSIONS Using a protocol of debridement, alignment, compression, stable fixation, bone grafting and early motion, patients aged 75 years or older can reliably achieve healing when faced with a nonunion of the humerus or femur.

Treatment of Femoral Shaft Pseudarthrosis, Case Series and Medico-Legal Implications. J Clin Med 2022; 11:jcm11247407. [PMID: 36556022 PMCID: PMC9787375 DOI: 10.3390/jcm11247407] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/30/2022] [Revised: 11/14/2022] [Accepted: 12/13/2022] [Indexed: 12/15/2022] Open
Abstract
Pseudarthrosis (PSA) is a possible complication of femoral shaft fracture treatment. It is often associated with reduced bone quality and can, therefore, adversely affect quality of life. Its treatment poses a major challenge for orthopaedic surgeons. Several authors have set forth different surgical approaches for the treatment of pseudarthrosis, such as internal fixation with plate and screws, replacement of an intramedullary nail or prosthetic replacement. In cases associated with bone loss, osteopenia, or comminution of fracture fragments, autologous or homologous bone grafts may also be used. The chronic outcomes of the surgical treatment of femoral shaft pseudarthrosis, even when consolidation is achieved, are linked to disabling sequelae of clinical-functional relevance, deserving an adequate medico-legal evaluation. The purpose of this retrospective study is to analyse a clinical case series of patients treated for atrophic femoral shaft pseudarthrosis at the IRCCS Orthopaedic Institute Galeazzi, Milan, Italy, from 2014 to 2020 and their orthopaedic-traumatological and medico-legal implications.

Abstract
Background and Purpose: Complicated femur fracture represents a major challenge for the orthopedic surgeon, with failed internal fixation, nonunion with broken intramedullary nail (IMN), and infected nonunion among the complications. Mechanical instability, as well as the poor biological environment, is considered as a concern when treating these cases. The purpose of this study was to evaluate concomitant IMN and plate augmentation as a single-stage procedure for the management of multiply operated nonunited femoral shaft fractures. Materials and Methods: Between January 2015 and May 2018, nine patients (eight men) with an average age of 40.8 years (range 25–70) diagnosed as nonunion femoral fractures after an average of four previous surgeries (range 2–6). All patients were available for follow-up with an average of 22 months (range 12–36). Results: The average time for fracture union was 6.7 months (range 3–12); five patients needed bone grafting to compensate for the bone defect encountered during the initial procedure, and two patients required secondary bone grafting after 6 months follow-up. Two patients presented with surgical site infection which was treated by antibiotics and daily dressing. The average leg length discrepancy at last follow-up was 1 cm (range 0.5–1.5). No patient had a metalwork failure or needed removal of the implants. Conclusion: In treating complicated multiply operated nonunited femoral shaft fractures, we believe that this technique can provide a robust mechanical foundation as well as an improved biological environment for such nonunited fractures to heal.

Abstract
PURPOSE The aims of this retrospective study were to evaluate the effective treatment of femoral nonunion using the technique of "autologous bone grafting through channels" combined with double-plate fixation. METHODS In this study, 186 patients with nonunion fracture of femur who underwent surgery using the technique of "autologous bone grafting through channels" combined with double-plate fixation in Hong Hui Hospital from May 2010 to July 2020 were enrolled. Totally, 122 males and 64 females with mean age of 44 years were evaluated. These patients were evaluated for the full clinical and radiological union time, duration of follow-up, levels of post-operative limb shortening, and range of motion of adjacent joints, and incidence of serious complications. RESULTS The mean follow-up time was 22 ± 6.2 months (range 12-44 months). Mean union time from surgery using our technique to full clinical and radiological union was 7.6 ± 1.2 months (range 4-9 months). All patients have achieved the union after one operation or two operations using the technique. The one-operation union rate is 98.4%. Post-operative severe complications were seen in seven patients which included deep vein thrombosis; the surgical site infection and the fracture nonunion. The range of motion in the adjacent joint of 17.7% (33/186) in all patients have an effect to the limb function. Six patients have the limb shortening more than 10 mm after surgery. CONCLUSION The technique of "autologous bone grafting through channels" combined with double-plate fixation is showed to be safe, effective, and easy to master and operate surgical option for treating the femoral nonunion.

Abstract
OBJECTIVE To investigate the effectiveness of tunnel osteogenesis technique combined with locking plate in the treatment of aseptic non-hypertrophic nonunion of femoral shaft. METHODS The clinical data of 23 cases of aseptic non-hypertrophic nonunion of femoral shaft treated with tunnel osteogenesis technique combined with locking plate between January 2017 and December 2020 were retrospectively analysed. There were 17 males and 6 females with an average age of 41.4 years (range, 22-72 years). There were 22 cases of closed fracture and 1 case of open fracture. The types of internal fixation at admission included intramedullary nail in 14 cases and steel plate in 9 cases. The number of nonunion operations received in the past was 0 to 1; the duration of nonunion was 6-60 months, with an average of 20.1 months. Among them, there were 17 cases of aseptic atrophic nonunion of the femoral shaft and 6 cases of dystrophic nonunion. Twenty-two cases were fixed with 90° double plates and 1 case with lateral single plate. The operation time, theoretical blood loss, hospitalization stay, nonunion healing, and postoperative complications were recorded. Harris hip function score, Lysholm knee function score, lower extremity function scale (LEFS), and short-form 36 health survey scale (SF-36) were used at last follow-up to evaluate hip and knee functions. Visual analogue scale (VAS) score was used to evaluate the relief of pain at 1 day after operation and at last follow-up. RESULTS The average operation time was 190.4 minutes, the average theoretical blood loss was 1 458.4 mL, and the average hospitalization stay was 8.2 days. All the 23 patients were followed up 9-26 months, with an average of 18.2 months. The healing time of nonunion in 22 patients was 3-12 months, with an average of 5.6 months. There were 8 cases of limb pain, 8 cases of claudication, 6 cases of limitation of knee joint movement, and 2 cases of limitation of hip joint movement. At last follow-up, the imaging of 1 patient showed that the nonunion did not heal, accompanied by pain of the affected limb, lameness, and limitation of knee joint movement. At 1 day after operation, the VAS score of 23 patients was 6.5±1.8, the pain degree was good in 7 cases, moderate in 12 cases, and poor in 4 cases; at last follow-up, the VAS score was 0.9±1.3, the pain degree was excellent in 21 cases and good in 2 cases, which were significantly better than those at 1 day after operation ( t=12.234, P<0.001; Z=-5.802, P<0.001). At last follow-up, the average Harris hip function score of 22 patients with nonunion healing was 94.8, and the good rate was 100%; Lysholm knee function score averaged 94.0, and the excellent and good rate was 90.9%; LEFS score averaged 74.6; SF-36 physical functioning score averaged 85.0 and the mental health score averaged 83.6. CONCLUSION Tunnel osteogenesis technique combined with locking plate in the treatment of aseptic non-hypertrophic nonunion of femoral shaft has a high healing rate and fewer complications, which can effectively relieve pain and improve lower limb function and quality of patients' life.

Abstract
Background An 8-year-old, 18.9 kg, male, intact Kai Ken with a femoral shaft fracture experienced recurrent implant breakage after two fracture reductions using an internal fixator. Objectives This case report is aimed at using a three-dimensional (3-D) printer to diagnose residual femoral rotational deviation. Implant failures and malunion occurred after two attempts at synthesis. Thus, a 3-D model was designed for preoperative planning of a third surgery. Methods To evaluate the alignment in the postoperative state after the second surgery, we removed a broken plate from the affected limb. Subsequently, a computed tomography image produced a bone replica using 3-D printing. The distal fragment was fixed and rotated externally by 42°. In addition to correcting the rotational deformity of the femur, we used an intramedullary pin and two locking plates to stabilize the proximal and distal femoral fracture segments. Results The bone union was confirmed four months after surgery, and no postoperative complications were observed 11 months after surgery. Conclusion 3-D printing is a valuable tool that increases the accuracy of presurgical planning.

Abstract
BACKGROUND The optimal treatment strategy for the surgical management of femur fractures and non-unions remains unknown. The aim of this study is to assess union rates, complications and outcome after femoral double plating. Treatment of shaft, distal, periprosthetic fractures and pathological proximal femur fractures as well as femoral non-unions with double plating were evaluated. METHODS A systematic review according to the Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) statement was conducted. Published literature reporting on the treatment and clinical outcome of femoral fractures and non-unions with double plating was identified. In total, 24 studies with 436 cases of double plating, 64 cases of single plating, 84 cases of intramedullary nailing (IM), and 1 interfragmentary screw treatment met the inclusion criteria of this systematic review. The evaluated literature was published between 1991 and 2020. RESULTS Double plating of femoral fractures achieved high healing rates and few complications were reported. It displayed significantly less intraoperative haemorrhage, shorter surgery time reduced risk of malunion in polytraumatised patients when compared to IM. Fracture healing rate of double-plating distal femoral fractures was 88.0%. However, there were no significant differences regarding fracture healing, complication or functional outcome when compared to single plating. Treatment of periprosthetic fractures with double plating displayed high healing rates (88.5%). Double plating of non-unions achieved excellent osseous union rates (98.5%). CONCLUSIONS The literature provides evidence for superior outcomes when using double plating in distal femoral fractures, periprosthetic fractures and femoral non-unions. Some evidence suggests that the use of double plating of femoral fractures in polytraumatised patients may be beneficial over other types of fracture fixation. LEVEL OF EVIDENCE IV.

Abstract
Background Although double-plate fixation (DP), i.e., fixation with a combination of a main lateral plate (LP) and a support medial plate (MP), is a relatively mature method for treating femoral shaft non-union with bone defect causes complications. The purpose of this study was to evaluate LP fixation with a 3D-printed, personalized, biomechanics-specific β-TCP bioceramic rod system (LP + 3DpbsBRS) as an alternative with less collateral damage. Methods Structure-specific finite element modelling was used to simulate femoral shaft non-union with bone defects and treatment with an LP only as the blank control. Then, the peak von Mises stress (VMS), the VMS distribution, and the plate displacement were determined to compare the effectiveness of LP + CBG (cancellous bone grafting), DP + CBG, and LP + 3DpbsBRS under 850 N of axial force. Results Our results indicated that the peak VMS was 260.2 MPa (LP + 3DpbsBRS), 249.6 MPa (MP in DP + CBG), 249.3 MPa (LP in DP + CBG), and 502.4 MPa (LP + CBG). The bending angle of the plate was 1.2° versus 1.0° versus 1.1° versus 2.3° (LP + 3DpbsBRS versus MP in DP + CBG versus LP in DP + CBG versus LP + CBG). Conclusion The 3DpbsBRS in the LP + 3DpbsBRS group could replace the MP in the DP + CBG group by providing similar medial mechanical support. Furthermore, avoiding the use of an MP provides better protection of the soft tissue and vasculature.

Abstract
OBJECTIVE The treatment of femoral nonunion is challenging for both the surgeon and the patient. Strut allografts increase the bone stock, enhance fracture healing and increase stability by acting as a biological plate. In this study, we aimed to report the results of the sandwich technique with two-strut allograft in the treatment of oligotrophic or atrophic femoral nonunions. METHODS Medical records of the patients who were treated due to femoral nonunion in a single center were retrospectively reviewed. Twenty-one patients (10 males, 11 females) with a mean age of 49 (range: 21 to 79) years were included in the study. The left side was affected in 11 patients, whereas the right side was affected in ten. The patients had 11 femoral shaft fractures, seven proximal femoral fractures and three distal femoral fractures. The mean time from the previous operation to the nonunion surgery was 9.6 (range: 6 to 22) months. RESULTS Union was achieved in all patients after a mean period of 6.2 (range: 4 to 10) months. The mean follow-up time was 46.8 (range: 12 to 86) months. One patient had superficial surgical site infection in the autologous graft donor site. CONCLUSION The sandwich technique with two-strut allograft provides good results in the treatment of femoral nonunion. The technique can be used on any type of nonunion, at any segment of the femur and can be combined with different fixation techniques.

Abstract
INTRODUCTION Lateral locked plating is a standard treatment option for distal femur fractures. However, the unstable conditions after lateral locked plating are increasing. The objective of this study was to investigate the biomechanical strength of additional medial plate fixation over the unstable lateral locked plating of distal femur fractures. MATERIALS AND METHODS A distal femur fracture model (AO/OTA 33-A3) was created with osteotomies in the composite femur. Three study groups consisting of 6 specimens each were created for single-side lateral locked plating with 6 distal locking screws (LP-6), single-side lateral locked plating with 4 distal locking screws (LP-4), and additional medial locked plating on LP-4 construct (DP-4). A compressive axial load (10 mm/min) was applied in the failure test. Mode of failure, load to failure, and ultimate displacement were documented. RESULTS All single-side lateral locked plating (LP-4 and LP-6) showed plate bending at the fracture gap, while none of the DP-4 showed plate bending at the fracture gap. Load to failure of DP-4 (mean 5522 N) was 17.1% greater than that of LP-6 (mean 4713.3 N, p < 0.05) and 29.2% greater than that of LP-4 (mean 4273.2 N, p < 0.05). Ultimate displacement of DP-4 (mean 5.6 mm) was significantly lower than that of LP-6 (mean 8.8 mm, p < 0.05) and LP-4 (mean 9.1 mm, p < 0.05). CONCLUSIONS Additional fixation of medial plate significantly increased the fracture stability in distal femur fractures fixed with the lateral locked plating. Especially in the clinical situations where sufficient stability cannot be provided at the distal segment, the medial plate may be considered as a useful biomechanical solution to obtain adequate stability for fracture healing.

Abstract
PURPOSE The aims of the present study were to evaluate and report the therapeutic outcomes of double-plate fixation in combination with autogenous bridging bone grafting in treatment of nonunion fractures of femur. METHODS In this retrospective case series study, 41 patients with nonunion fracture of femur who underwent surgery by double-plate fixation and autogenous bridging bone grafting in academic referral center from July 2010 to July 2015 were enrolled. Totally, 32 males and 9 females with mean age of 35 years were evaluated. They were evaluated for related risk factors, previous therapeutic methods, time interval between injury to nonunion surgery and surgery to full clinical and radiological union, duration of follow-up, levels of postoperative limb shortening, and movement limitations. RESULTS Ten patients had open fractures and eight patients had infected nonunion in the femoral supracondylar, subtrochanteric, and shaft fractures. Nailing was the most common used method as the primary treatment of femoral shaft fractures. In addition, the mean follow-up time was 37 months. Full union was obtained even in infected cases. Deep vein thrombosis was found in one patient and pulmonary thromboembolism in another patient, and both patients were treated successfully. Moreover, limitations of articular movements were seen in seven patients. CONCLUSION Double-plate fixation in combination with bridging bone grafting is an effective method in the treatment of nonunion of femoral supracondylar, subtrochanteric, and shaft fractures even in the infected cases.

Augmentative antirotational plating provided a significantly higher union rate than exchanging reamed nailing in treatment for femoral shaft aseptic atrophic nonunion - retrospective cohort study. BMC Musculoskelet Disord 2019; 20:127. [PMID: 30909909 PMCID: PMC6434807 DOI: 10.1186/s12891-019-2514-3] [Citation(s) in RCA: 14] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/07/2018] [Accepted: 03/17/2019] [Indexed: 12/15/2022] Open
Abstract
Background Atrophic nonunion of femoral shaft fracture after intramedullary (IM) nailing is uncommon. The treatment for femoral shaft aseptic atrophic non-union remained controversial. The aim of this study was to compare the surgical results between exchanging reamed nailing (ERN) and augmentative antirotational plating (AAP) for femoral shaft aseptic atrophic nonunion. Methods We retrospectively reviewed the patients with femoral shaft nonunion between the year of 2014 and 2015. The patients with nonunion after plate osteosynthesis, septic nonunion, hypertrophic nonunion, additional surgery during revision surgery were excluded. All the patients were followed up at least 12 months. Results Overall, the union rate after revision surgery was 70.8%. The union rate was significantly higher in the AAP group than in the ERN group. Operating time was also significantly shorter in the AAP group. Regarding the location of nonunion, the union rate was comparable between groups for isthmic nonunions. However, for non-isthmic nonunions, the union rate was significantly higher and operating time was significantly shorter in the AAP group. Conclusion AAP showed an overall higher union rate for management of femoral shaft aseptic atrophic nonunion compared with ERN. Especially for non-isthmic femoral shaft atrophic nonunions, AAP provided a significantly higher union rate and significantly shorter operating time.

Abstract
OBJECTIVE To investigate the efficacy of the treatment of atrophic nonunion using structural autogenous ilium bone grafting in combination with vertical fixation of double plates. METHODS This retrospective study analysed the clinical data from consecutive patients with atrophic nonunion who underwent autogenous ilium grafting in combination with double-plate vertical fixation. The injury type and the bone affected by nonunion, the duration of nonunion and the outcomes following surgery were recorded for all patients. RESULTS The study enrolled 43 patients with atrophic nonunion of the upper and lower limbs: 17 patients with tibial nonunion, 21 with femoral nonunion, four with humeral nonunion and one with radial shaft nonunion. The mean duration of postoperative follow-up was 14.5 months (range, 8-28 months). A total of 43 of 43 patients (100%) achieved a healed nonunion fracture without the occurrence of complications such as infection, fracture of internal fixation or pain in the harvesting site. Comprehensive postoperative assessments of bone healing and function were observed to be good and/or excellent in all 43 patients. CONCLUSION Structural autogenous ilium grafting used in combination with double-plate vertical fixation can provide a stable structural environment for near optimal bone healing in patients with atrophic nonunion.

Abstract
Background By comparing clinical outcomes between dual plating (DP) and exchange nailing with augmentation plating (EN/AP), we aimed to provide better treatment strategies for femoral shaft non-union. Methods We retrospectively reviewed 30 patients with aseptic femoral shaft non-union at our level 1 trauma center between January 2014 and January 2017. All patients underwent a one-stage, definitive revision procedure, including DP for 16 patients and EN/AP for 14 patients. Perioperative surgical trauma, fracture healing, complications, and the time to return to work were evaluated. Results Twenty-nine patients achieved fracture healing. In the EN/AP group, the fracture healing rate was 100%, the healing time was 5.7 ± 1.7 months, and the time of return to work was 8.2 ± 2.9 months. In the DP group, the fracture healing rate was 94%, the healing time was 8.4 ± 4.1 months, and the time of return to work was 18.4 ± 10.3 months. In terms of fracture healing and return to work, the patients in the EN/AP group required less time than those in the DP group, and the differences were statistically significant (p = 0.024 and p < 0.01 respectively). Except for the length of the incision, the two groups showed no statistically significant differences in operative time, postoperative deformity, and complications. Conclusions Both EN/AP and DP are important surgical options for femoral shaft non-union. Compared to DP, EN/AP resulted in a shorter incision, faster fracture healing, and a shorter time to return to work. Trial registration ChiCTR-ORC-17014062

Abstract
Treatment of complex osteoporotic distal femur fractures with the Less Invasive Stabilization System (LISS) has been associated with high complication rates. The aim of this study was to investigate the biomechanical competence of two different techniques of augmented versus conventional LISS plating. Unstable distal femoral fracture AO/OTA 33-A3 was created via osteotomies in artificial femora simulating osteoporotic bone. Three study groups, consisting of 10 specimens each, were created for fixation with either LISS plate, LISS plate with additional polylactide intramedullary graft, or LISS plate plus medial locking plate (double plating). All specimens were non-destructively tested under axial (20-150 N) and torsional (0-4 Nm) quasi-static loading. Each bone-implant construct was tested with two different working length (WL) configurations (long and short) of the LISS plate. Relative movements between the most medial superior and inferior osteotomy aspects were investigated via three-dimensional motion tracking analysis. Double plating revealed significantly smaller longitudinal and shear displacement than the other two techniques (p ≤ 0.001). In addition, LISS plus graft fixation was with significantly less longitudinal displacement in comparison to conventional LISS plating (p < 0.001). Long WL resulted in significantly higher longitudinal and shear displacement compared to short WL for LISS and LISS plus graft (p ≤ 0.032), but not for double plating (p > 0.999). In conclusion, intramedullary grafting resulted in significantly increased fracture stability under axial loading in comparison to conventional LISS plating. Although it was not efficient enough to provide comparable stability to double plating, intramedullary grafting may be considered as a useful biological alternative to the latter in a surgeon's armamentarium. © 2018 Orthopaedic Research Society.

Abstract
INTRODUCTION Periprosthetic femoral fractures (PFF) around tumor prosthesis of knee are stubborn problems for surgeons, huge bone defect and inappropriate biomechanics of the revision implant design can be disaster for reconstruction. With the development of three-dimensional (3D) printing technology, surgeons participate more in precise preoperative design and simulation for treatment of such fractures. In this study we explored an accurate and feasible way to restore normal anatomy and function of the knee joint with 3D printing technology. CASE PRESENTATION Rationale: This report explored an accurate and feasible way to treat PFF around tumor knee prosthesis in a 32 years old women with 3D printing technology, which restored normal anatomy and function of the knee joint. Patient concerns: Pain in left thigh lasted for 10 months after resection of left femoral chondroma and knee joint replacement four years ago. Diagnoses: periprosthetic femoral fractures (PFF) around tumor knee prosthesis. INTERVENTIONS CT images of the patient were collected and reconstructed. Parameters of bilateral femurs were virtually sliced and measured. Novel femoral stem and nail paths were specially designed by doctors according to these parameters. The prosthetic femoral stem components and navigator were customized by engineers according to the doctor's design. The residual femoral resin model, customized components and navigator were printed with Stereo Lithography Apparatus 3D printer. The shape-preconcerted allograft bone was selected as patch for the bone defect before operation with the printed bone model. All the steps were simulated preoperatively with the models printed, and then the operation was carried out. OUTCOMES The operation was successfully performed. The postoperative x-ray image, MSTS93 scores were examined and the function restoration sustained well in the follow-up period from 1 month to 27 months. LESSONS 3D printing and medical interaction are key points in complex PFF cases. CONCLUSION As for PFF of the complex tumor of knee, preoperative design and simulation with 3D printing technology may provide more accurate and effective operative outcome than traditional methods, which might be considered as a method suitable for popularization in complex and severe cases.

Finite Element Analysis of Different Double-Plate Angles in the Treatment of the Femoral Shaft Nonunion with No Cortical Support opposite the Primary Lateral Plate. BIOMED RESEARCH INTERNATIONAL 2018; 2018:3267107. [PMID: 30151378 PMCID: PMC6091371 DOI: 10.1155/2018/3267107] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 01/21/2018] [Revised: 05/09/2018] [Accepted: 07/09/2018] [Indexed: 01/14/2023]
Abstract
Objectives We evaluated the biomechanical outcome of different plate fixation strategies (the single plate construct, 45° double-plate construct, 90° double-plate construct, 135° double-plate construct, and 180° double-plate construct) used for the fixation of the femoral shaft nonunion with no cortical support opposite the primary lateral plate. This may help surgeons choose the optimal therapy to the femoral shaft nonunion. Methods The femoral shaft nonunion with no medial support and the models of lateral plate and medial plate was constructed in 3-matic software and UG-NX software, respectively. We then assembled the single plate and different double plates to the fracture model separately to form the fixation models. After meshing the models' elements, we used the ABAQUS software to perform the finite element analysis. Values of the von Mises Stress (VMS) distribution of the implant, peak VMS, and model displacement and deformation were used to capture the mechanical factors in this study. Results Our results indicated that the peak von Mises Stress (VMS) of the lateral plate was concentrated in middle surface of the lateral plate near the fragment of each group. The peak VMS was 5201.0 MPa (the single-plate construct), 3490.0 MPa (45° double-plate construct), 1754.0 MPa (90° double-plate construct), 1123.0 MPa (135° double-plate construct), and 816.5 MPa (180° double-plate construct). The additional short plate dispersed some stress leading to the decrease in the peak VMS of the lateral plate. As angle formed by the double plates increased, the dispersed function of the additional plate was becoming obvious. The bending angles of the lateral plate were 18° versus 12° versus 3° versus 2° versus 1° (the single-plate construct versus 45° double-plate construct versus 90° double-plate construct versus 135° double-plate construct versus 180° double-plate construct). Conclusions Our study indicated that increasing the angle between the plates in a double-plate construct improves the stability of the construct over a single lateral plate when there is no cortical support opposite to the lateral plate. The strongest fixation occurred when the angle between the two plates was greater than ninety degrees.

Abstract
Objective To review the recent advances in treatment of aseptic femoral shaft nonunion. Methods The clinical studies about the treatments of aseptic femoral shaft nonunion in recent years were widely reviewed and analyzed. Results There are several surgical methods for aseptic femoral shaft nonunion. Due to uncertain clinical outcome, dynamization of nail should be carefully selected. The exchange nailing is suitable for the hypertrophic nonunion of the isthmal femoral shaft fracture. The exchange lateral plating is suitable for nonunion with obvious malformation. However, wave plate or dual plate should be chosen when the bone nonuinon is combined with the medial defect. The augmentation plating improves the success rate of nailing for femoral shaft nonunion, but it should be carefully selected for patients with obvious deformity or bone defect. Ilizarov technique is suitable for various bone nonunion, especially with complicated or large segmental bone defects. Induced membrane technique is also an important method for the treatment of bone nonunion with large bone defects. The clinical efficacy of the blocking screw remains to be supported by further evidence. Biological stimulants are mainly used for atrophic nonunion, and the clinical efficacy of them alone are still controversial. Conclusion Due to lack of comparative studies between different surgical methods, the orthopedist should choose the appropriate treatment according to the individual situations of the patient and the types of bone nonunion.

Abstract
PURPOSE Intramedullary nailing (IMN) is a popular method in the management of femoral shaft fractures (FSFs). However, whether the association of IMN with pulmonary fat emboli can compromise the pulmonary and nervous systems is debatable. The purpose of this study is to compare IMN with the locked dual plating (LDP) method by assessing the clinical outcomes of FSF patients with head or chest injury. METHOD A total of 126 FSF patients were included in this study between January 2010 and July 2016 and divided into LDP and IMN groups. Patient demographic characteristics, operative time, blood loss, Harris Hip Score, Lysholm Knee Score, radiological outcomes, and systemic complications were collected and compared between the two treatment groups. Patients were followed up for at least 12 months. RESULTS The LDP group performed better than IMN in terms of operative time, estimated blood loss amount, and malunion rate. Differences in function scores, fracture union rate, overall pulmonary complication rate, and in-hospital mortality between the two groups were not significant. Average radiographic union time was significantly longer in the LDP group (36.3 weeks) than in the IMN group (32.5 weeks). One case of fixation failure occurred postoperatively in the LDP group, whereas one case of fracture nonunion took place in the IMN group. CONCLUSION Our findings suggest that dual-plating fixation is a promising method for FSFs with multiple injuries. However, the retrospective nature of this study necessitates high-quality trials to be performed to assess the clinical efficiency of dual plating.

Abstract
INTRODUCTION Femoral shaft fractures are one of the common injuries that is treated by open reduction, with internal fixation by plate and screws or intramedullary nailing, which can achieve a high union rate. AIM To evaluate the outcome of using closed external fixation to augment a failing plate; with signs of screw loosening and increasing bone/plate gap; a failed plate; broken plate; screws completely out of bone with redisplacement of fracture. MATERIALS AND METHODS A retrospective study on 18 patients, aged between 17-42 years, who presented between 6-18 weeks after initial surgical fixation, with pain, difficulty in limb function, deformity and abnormal movement at fracture site, was done. X-Rays showed plating failure with acceptable amount of callus, which unfortunately had refractured. Cases associated with infection and no radiological evidence of callus formation were excluded from this study. Closed reduction was done by manipulation, then fracture fixation by AO external fixator. The patients were encouraged for full weight bearing as early as possible with dynamization later on. RESULTS Of the 18 patients who underwent external fixation after close reduction, 15 cases showed bone healing in a period between 11-18 weeks (mean of 14.27 weeks) with good alignment (Radiologically). Removal of external fixator was done followed by physical therapy thereafter. CONCLUSION Closed external fixation for treatment of failing or failed femoral plating, achieves good success rate and has less complications, is a short time procedure, especially in a hospital with limited resources.

Abstract
Non-union of the humeral shaft is infrequently noticed after surgical fixation. Sixty eight patients whose osteosynthesis of humeral shaft had failed leading to non-union were identified over a duration of 10 years from (January 2006 to December 2015). Clinical and radiographical follow-up was available for 64 patients (4 patients were lost for follow-up), with a mean age of 58 years (range 25-78 years). All patients had aseptic atrophic non-union of either: proximal shaft (n=12), mid shaft (n=38), and lower shaft (n=14). All these patients had failure of primary fixation, with a minimum duration from 36 to 110 weeks. Non-unions were operated by excision of non-union, autogenous bone grafting and osteosynthesis by locking compression plating. Adequate fixation of non-union with bone grafting was achieved in all patients. All non-unions healed well at an average of 16 weeks (range 6-36 weeks). The mean length of follow-up was 120 weeks (range 60-250 weeks). The mean range of movements following healing of non-union was forward flexion of 140°, external rotation and internal rotation of 30° at shoulder and average fixed flexion deformity of 10° and flexion of 130° at elbow. Two patients had postoperative radial nerve palsy because of neuropraxia, which recovered in eight weeks. Three patient developed superficial infections at the iliac crest, which settled with antibiotics, dressings in 3 weeks time and two patients had some discomfort over the fibular graft harvest site. In all patients complete clinical and radiological union was achieved with satisfactory outcome in terms of relief of symptoms and functional improvement in the range of movements. The main points in surgical treatment were complete excision of non-union, correction of deformity, use of plenty of corticocancellous graft, furthermore the use of intramedullary fibula and osteosynthesis by long locking compression plating in different modes of fixation provided good to excellent results and clinical outcome.

Abstract
INTRODUCTION Non-union following interlocking nailing is a troubling complication in treatment of shaft femur fractures. There is no clear consensus on the treatment of this problem. This research was undertaken to study the role of augmentation plating combined with exchange nailing in such cases. PATIENTS AND METHODS A prospective clinical study was undertaken from January 2010 to December 2015. Patients with aseptic femoral shaft non-union, with or without implant failure following intramedullary nailing were included in the study. Augmentation plating combined with Exchange Nailing with a 4.5mm LCP was done. RESULTS Fifteen patients (nine male and six female) with an average age of 43.7 years (range 18-67 years) were treated. Average timing from the first surgery was 7.3 months. Complete clinical and radiological union was achieved in all cases in a mean duration of 5.2 months. Average duration of follow up was 12.6 months. All the patients retained the preoperative hip and knee range of motion till the last follow up. CONCLUSION Augmentation plating combined with exchange nailing in non-unions following intramedullary nailing of femur shaft fractures is a reasonably good and effective procedure with a very high success rate.

Abstract
INTRODUCTION AND PURPOSE Challenges to the surgeon in managing cases of resistant non-union of the distal femur include poor bone stock, disuse osteopenia and joint contractures. Procedures varying from simple bone grafting to megaprosthesis revision have been described. We successfully managed such cases using our technique of combining cortical allograft struts to augment the defect in the femoral condyle coupled with autogenous iliac crest bone grafting and locking plate osteosynthesis. MATERIALS AND METHODS Between April 2012 and May 2014, 22 patients who presented with resistant nonunions of the distal femur following initial surgery were managed using this technique. Cortical allograft struts were taken from the tissue bank of our institution. All patients were followed up post operatively and their time to union was noted. Functional outcome was calculated using LEFS (Lower extremity functional score). The average follow up of all our patients was 24 months. RESULTS All patients went on to achieve complete bony union. The average union time was 6.2 months (5 to 8 months). One patient who was a diabetic had superficial infection post operatively which was treated successfully with IV antibiotics. Average knee flexion was 110 degrees (80 to 130 degrees). The mean LEFS score was 72 (59 to 79). CONCLUSION Combing a locking plate fixation with the bone grafting technique of using an allograft strut to support the metaphyseal medial bone defect and autografts gives a good union and a good functional outcome in the management of resistant non-unions of the distal femur by enhancing the biology and providing a good structural support to the distal femur.

Abstract
BACKGROUND Femoral diaphyseal non-unions present difficult scenario to manage. There are multiple options but most of them still report varying incidences of failure. We combined the principles of augmented plating and exchange nailing and aim to study the effectiveness of this technique. METHOD A retrospective study at a tertiary trauma centre was conducted. Seventy patients (60 men, 10 women), average age 40.7±15.27 years (range 18-81 years) with diaphyseal femoral fracture non-unions treated between July 2010 and January 2015 were reviewed. The average interval between first and the last surgery was 18.07±17.65 months (range 4-96 months). Forty six patients had hypertrophic non-union and 24 patients had atrophic non-union. Twenty one patients had undergone a prior surgery for non-union, 13 dynamisation, 4 bone grafting, 1 augmented plating and 3 exchange nailing. Non-unions were treated with implant removal, freshening of bone edges and exchange K-nailing and augmented plating. Autologous bone grafting and raising of osteoperiosteal flaps was done in all cases. Outcome measures were radiographic evidence of fracture union at minimum three out of four cortices, knee range of motion as compared to opposite knee, and study of complications. RESULTS All patients demonstrated radiographic evidence of fracture union with an average time of 16.77±2.38 weeks (range 12-26 weeks). Mean knee range of motion of unaffected limb was 126±9.76° (range 90-140°) while in operated limb it was 121.1±11.36° (range 80-140°), p>0.01. Patients with hypertrophic non-unions, prior surgery for non-union and supra- or infra-isthmal non-unions had shorter union time. Two patients had superficial infection which was managed by superficial debridement and two patients had pain at proximal nail tip site which was managed by anti-inflammatory medication. None of the patients required additional surgery for implant removal. CONCLUSION Exchange K nailing with Bone graft and additional plating technique for non-union diaphyseal femur fracture achieved good union rates with minimal complication. In our series none of the patient required revision and the technique probably will further minimise the revision rates compared to current options for non-union femur.

Abstract
Objective This study was performed to evaluate the clinical outcomes in adult polytraumatized patients with thoracic injury and femoral shaft fractures treated with double-plating fixation. Methods From November 2010 to October 2014, 15 polytraumatized patients with femoral shaft fractures were enrolled in this retrospective study. Radiographic findings and functional outcomes were assessed at 1, 3, 6, and 12 months postoperatively. Results Fourteen (93%) of the 15 femoral shaft fractures achieved bony union, with a mean time to union of 9.2 months. The mean Nonarthritic Hip Score and Lysholm Knee Score was 89.4 and 87.2 points, respectively. The range of motion of the knee joint was comparable between the injured and uninjured legs (116° and 121°, respectively). Conclusions Our findings suggest that lower limb function returns to normal after orthogonal double-plating fixation, which is an alternative technique to intramedullary nailing for femoral diaphyseal fractures in patients with severe chest injury.

Abstract
INTRODUCTION The refractory post-operative diaphyseal femur fracture (DFF) non-union is extremely difficult to treat and remains severe challenges for orthopedists. Although several traditional internal fixations and novel biomedical techniques have been used in managing this complication, its treatment is still fraught with severe challenges. PATIENTS AND METHODS Starting from 1999, 5 patients after three previous internal fixation operations showing refractory DFF non-union underwent the comprehensive fibular autograft with double metal locking plates fixation (cFALP) surgery. The autogenous fibular was first harvested and non-evenly split into two halves in a longitudinal manner. After retracting all previous internal fixation(s), the larger half strut fibula was hammered into the femur canal while the smaller half was fragmented into small pieces and filled surrounding the DFF site. Two locking compression plate were fixed on the lateral and anterior (or antero-lateral) side of the femur, respectively. RESULTS The follow-up ranged from 60 to 96 weeks. All cases (100%) achieved bony union without severe complications. The mean time to union was 36±14.7 weeks (range 24-60 weeks). CONCLUSION The cFALP is a promising surgical modality for DFF non-union treatment. However, because fibular harvest may cause severe complications, the cFLAP should only be considered in refractory DFF non-union cases.
