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.

Effectiveness and safety of augmentative plating technique in managing nonunion following intramedullary nailing of long bones in the lower extremity: A systematic review and meta-analysis. Chin J Traumatol 2024:S1008-1275(24)00055-5. [PMID: 38762419 DOI: 10.1016/j.cjtee.2024.04.004] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/28/2023] [Indexed: 05/20/2024] Open
Abstract
PURPOSE To methodically assess the effectiveness of augmentative plating (AP) and exchange nailing (EN) in managing nonunion following intramedullary nailing for long bone fractures of the lower extremity. METHODS PubMed, EMBASE, Web of Science, and the Cochrane Library were searched to gather clinical studies regarding the use of AP and EN techniques in the treatment of nonunion following intramedullary nailing of lower extremity long bones. The search was conducted up until May 2023. The original studies underwent an independent assessment of their quality, a process conducted utilizing the Newcastle-Ottawa scale. Data were retrieved from these studies, and meta-analysis was executed utilizing Review Manager 5.3. RESULTS This meta-analysis included 8 studies involving 661 participants, with 305 in the AP group and 356 in the EN group. The results of the meta-analysis demonstrated that the AP group exhibited a higher rate of union (odds ratio: 8.61, 95% confidence intervals (CI): 4.12 - 17.99, p < 0.001), shorter union time (standardized mean difference (SMD): -1.08, 95 % CI: -1.79 - -0.37, p = 0.003), reduced duration of the surgical procedure (SMD: -0.56, 95 % CI: -0.93 - -0.19, p = 0.003), less bleeding (SMD: -1.5, 95 % CI: -2.81 - -0.18), p = 0.03), and a lower incidence of complications (relative risk: -0.17, 95 % CI: -0.27 - -0.06, p = 0.001). In the subgroup analysis, the time for union in the AP group in nonisthmal and isthmal nonunion of lower extremity long bones was shorter compared to the EN group (nonisthmal SMD: -1.94, 95 % CI: -3.28 - -0.61, p < 0.001; isthmal SMD: -1.08, 95 % CI: -1.64 - -0.52, p = 0.002). CONCLUSION In the treatment of nonunion in diaphyseal fractures of the long bones in the lower extremity, the AP approach is superior to EN, both intraoperatively (with reduced duration of the surgical procedure and diminished blood loss) and postoperatively (with an elevated union rate, shorter union time, and lower incidence of complications). Specifically, in the management of nonunion of lower extremity long bones with non-isthmal and isthmal intramedullary nails, AP demonstrated shorter union time in comparison to EN.

Abstract
BACKGROUND Non-unions after intramedullary nailing of femoral shaft fractures are a significant problem. Treatment options such as augmenting with plates or exchange nailing have been proposed. The ideal treatment remains controversial. METHODS Augmentative plating using a 4.5 mm LCP or a 3.2 mm LCP leaving the nail in situ was tested biomechanically and compared to exchange intramedullary nailing in a SawboneTM model of a femoral shaft non-union. RESULTS The difference of fracture gap motion in axial testing was small. In rotational testing, the exchange nail allowed for the largest amount of motion. The 4.5 mm augmentative plate was the most stable construct in all loading conditions. CONCLUSIONS Augmentative plating using a 4.5 mm LCP plate while leaving the nail in situ is biomechanically superior to exchange intramedullary nailing. A small fragment 3.2 mm LCP is undersized and does not reduce fracture motion sufficiently in a femoral shaft non-union.

Abstract
Background Exchange nailing is a standard treatment for femoral shaft nonunion after intramedullary nailing. However, substantial uncertainty and controversy remain regarding the mode of interlocking fixation. This study aimed to compare the success rate and time to union of exchange nailing based on interlocking modes. Methods We retrospectively analyzed all consecutive patients who underwent exchange nailing for aseptic femoral shaft nonunion between February 2000 and February 2021. Patients who underwent exchange nailing using the dynamically locked mode and statically locked mode constituted the dynamic group and static group, respectively. We compared the success rates of the index surgery and the time to union between the groups and measured the extent of interlocking screw migration on the dynamic oblong hole in the dynamic group. Results The dynamic group and static group comprised 17 patients and 18 patients, respectively. All patients in the dynamic group achieved bone union, whereas 5 patients in the static group did not and underwent additional intervention. The success rate of the index surgery was significantly higher in the dynamic group than in the static group (100% vs. 72.2%, p = 0.045). Four of the 5 failed unions in the static group achieved bone union after dynamization. The median time to union was significantly shorter in the dynamic group than in the static group (6.0 months [range, 4.0-6.0] vs. 12.0 months [range, 3.7-21.7], p = 0.035). In the dynamic group, 3 of 17 patients exhibited interlocking screw migration ranging from 1.1 to 4.1 mm. Conclusions Exchange nailing with dynamic mode yields a higher success rate and shorter time to union in aseptic femoral shaft nonunion than that with static mode, without the risk of excessive shortening.

The role of an augmentative plating in the management of femoral subtrochanteric nonunion. Arch Orthop Trauma Surg 2023:10.1007/s00402-023-04767-4. [PMID: 36624207 DOI: 10.1007/s00402-023-04767-4] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/23/2022] [Accepted: 01/03/2023] [Indexed: 01/11/2023]
Abstract
INTRODUCTION Owing to its distinct biomechanical properties, nonunion is common (7-20%) after intramedullary (IM) nailing of subtrochanteric femoral fractures. Unlike diaphyseal nonunion, it is difficult to provide sufficient stability by exchanging nailing alone in subtrochanteric nonunion. This study investigated the clinical outcomes of femoral subtrochanteric nonunion initially treated with an IM nail and subsequently managed with minimally invasive augmentative plate fixation. MATERIALS AND METHODS Nineteen patients were enrolled retrospectively. The mechanisms of initial injury were traffic accidents in 8, falls from a height in seven, and slipping in two patients. Two patients with atypical subtrochanteric femoral fractures without a specific trauma history were further included. All patients underwent IM nailing as the index operation. Nonunion surgery was performed an average of 45.2 weeks after the initial surgery. In cases of hardware damage and/or atrophic nonunion, exchange nailing and bone grafting were performed in addition to augmentative plating, as necessary. Conversely, augmentative plating alone was performed in cases of hypertrophic nonunion without any failure of the preexisting IM nail or malalignment. A narrow locking compression plate was fixed after contouring according to the shape of the proximal femur. The mean follow-up period was 36.1 months. RESULTS Bony union was achieved in 18/19 patients (94.7%), at an average of 19.8 weeks after nonunion surgery. In the case that did not heal even after exchange nailing, additional plating and bone grafting, further autogenous bone grafting was required after 11 months, which healed uneventfully. There were 2 cases of soft tissue irritation over the plate, but no major complications were observed. CONCLUSIONS Additional plate augmentation over a retained IM nail yields satisfactory outcomes in terms of the bony union in subtrochanteric nonunion. Given its expected biomechanical superiority and relatively easy surgical technique, it may be a reasonable option for the management of femoral subtrochanteric nonunion.

Abstract
OBJECTIVE Femoral shaft nonunion after intramedullary nailing fixation remains a challenge for orthopedic surgeons. This study evaluated osteoperiosteal decortication and iliac bone grafting combined with wave plating as a treatment for aseptic atrophic nonunion of the femoral shaft after intramedullary nailing. METHODS The study included 22 patients (two female, 20 male; mean age 40.8 years [range, 19-61]) with aseptic atrophic nonunion of the femoral shaft who underwent osteoperiosteal decortication and iliac bone grafting combined with wave plating between January 2016 and January 2020. Cases with infected nonunion, hypertrophic nonunion, and nonunion after plate osteosynthesis were excluded. Clinical outcomes were assessed retrospectively using the Samantha X-ray and Paley scale scores. RESULTS The mean follow-up period was 18.8 months (range, 12-35). Bone union was achieved in all patients. The average clinical healing time was 5.7 months (range, 3-14). The mean Samantha X-ray score was 5.7 ± 0.45 and the Paley scores indicated excellent or good clinical results in all cases. One patient developed sterile wound leakage that resolved after a dressing change. CONCLUSIONS Osteoperiosteal decortication and bone grafting combined with wave plating is an excellent treatment for aseptic atrophic nonunion of the femoral shaft after intramedullary nailing.

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.

Perioperative Radiographic Predictors of Non-Union in Infra-Isthmal Femoral Shaft Fractures after Antegrade Intramedullary Nailing: A Case-Control Study. J Clin Med 2022; 11:jcm11133664. [PMID: 35806947 PMCID: PMC9267532 DOI: 10.3390/jcm11133664] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/01/2022] [Revised: 06/18/2022] [Accepted: 06/22/2022] [Indexed: 11/23/2022] Open
Abstract
Antegrade intramedullary (IM) nailing is the gold standard treatment for femoral shaft fractures; however, the non-union rate of infra-isthmal femoral shaft fractures is still high after antegrade IM nailing. This retrospective case−control study aimed to determine the association between perioperative radiographic factors and the non-union of infra-isthmal femoral shaft fractures after antegrade IM nailing. Univariate and multivariate analyses were used to evaluate the radiographic risk factors of non-union. Ninety-three patients were included, with thirty-one non-unions and sixty-two matched controls between 2007 and 2017. All were regularly followed up for 2 years. Receiver operating characteristic analysis revealed that a ratio of the unfixed distal segment > 32.5% was strongly predictive of postoperative non-union. The risk factors for non-union were AO/OTA type B and C (odds ratio [OR]: 2.20), a smaller ratio of the distal fragment (OR: 4.05), a greater ratio of the unfixed distal segment (OR: 7.16), a higher ratio of IM canal diameter to nail size at the level of fracture (OR: 6.23), and fewer distal locking screws (OR: 2.31). The radiographic risk factors for non-union after antegrade IM nailing for infra-isthmal femoral shaft fractures were unstable fractures, shorter distal fragments, longer unfixed distal fragments, wider IM canal, and fewer distal locking screws. Surgeons must strive to avoid non-union with longer and larger nails and apply more distal locking screws, especially for unstable, wider IM canal, and shorter distal fragment fractures.

Abstract
BACKGROUND We modified the general application method of the pointed reduction clamp, focusing on the function of encompassing the fracture site, and applied it to femoral shaft fractures. The purpose of the present study is to describe the minimally invasive cerclage clamping technique (MICC) and compare radiological and clinical results of MICC with that of percutaneous cerclage wiring (PCW). MATERIALS AND METHODS A retrospective comparative study was performed in two institutions from 2010 to 2019. Patients aged ≥18 years with acute femoral shaft fractures that were treated with intramedullary nailing and reduced using MICC or PCW were included. Patients with open fractures, atypical fractures, and follow-up less than 12 months were excluded. A total of 68 patients were finally included and divided into two groups based on the reduction technique each patient underwent. We then compared radiological and clinical results between the two groups, including coronal and sagittal alignment, time for union, and complications. RESULTS The average time needed for the technique in the MICC group was shorter than that in the PCW group (7.1±4.6 min vs. 11.5±4.8 min, P < 0.001). There was no significant difference in the quality of reduction or alignment between the two groups. The mean union time was not different between the two groups (24.1±8.7 weeks vs. 24.1±8.6 weeks, P = 0.990). The MICC group had one nonunion patient and the PCW group had one postoperative infection patient. There were no cases of major neurovascular injury such as femoral artery injury or sciatic nerve palsy. CONCLUSIONS MICC, using a pointed reduction clamp for nonisthmal femoral shaft fractures, demonstrated satisfactory reduction and favorable surgical outcomes with intramedullary nailing. We believe that MICC can be a reliable and safe reduction method for femoral shaft fractures.

Abstract
Objective To investigate the effectiveness of the treatment under the guidance of "diamond concept" for femoral shaft fractures nonunion after intramedullary fixation. Methods Between January 2014 and December 2016, 21 cases of femoral shaft fractures nonunion after intramedullary fixation were treated with auxiliary plate fixation combined with autogenous iliac graft, and autologous bone marrow concentrate and platelet-rich plasma (PRP) gel under the guidance of the "diamond concept". There were 13 males and 8 females, with an average age of 32.5 years (range, 17-48 years). All fractures were closed femoral shaft fractures. Four patients underwent internal fixation with plate and resulted in nonunion, then they were fixed with intramedullary nails, but did not heal either. The rest 17 patients were fixed with intramedullary nailing. Fracture nonunion classification: 4 cases of hypertrophic nonunion, 17 cases of atrophic nonunion; the length of bone defect was 1-3 mm; the duration from the last treatment to the current treatment was 10-23 months (mean, 14.3 months). The operation time, intraoperative blood loss, the time between operation and full loading, fracture healing time, and complications were recorded. The visual analogue scale (VAS) score and the imaging system of fracture healing of the extremities (RUST) of patients before operation and at last follow-up were recorded to evaluate the fracture healing; the function of the affected limb was evaluated according to the Schatzker-Lambert efficacy score standard at last follow-up. Results The operation time was 105-160 minutes, with an average of 125.6 minutes; the intraoperative blood loss was 160-580 mL, with an average of 370.5 mL. All incisions healed by first intention, without vascular or nerve injury. All patients were followed up 22-46 months (mean, 26.5 months). All the fractures healed, with a fracture healing time of 3-7 months (mean, 4.8 months). During the follow-up, there was no infection, loosening, implant breakage, re-fracture, and other complications. The VAS score at last follow-up was 0.8±0.3, showing significant difference ( t=7.235, P=0.000) when compared with preoperative score (5.2±3.7); the RUST score was 3.4±0.3, which was significantly higher than the preoperative score (1.5±0.7) ( t=8.336, P=0.000). According to the Schatzker-Lambert effectiveness evaluation standard, the limb function was excellent in 16 cases, good in 4 cases, fair in 1 case, and the excellent and good rate was 95.42%. Conclusion Nonunion after intramedullary fixation of femoral fracture treated with auxiliary plate combined with autogenous iliac graft, autogenous bone marrow concentration and PRP gel in accordance with the "diamond concept" can not only restore the stability of the fracture ends, but also improves the biological environment of the fracture site, and can improve the rate of fracture healing.

Abstract
Objective To review the history, current situation, and progress of augmentation plate (AP) for femoral shaft nonunion after intramedullary nail fixation. Methods The results of the clinical studies about the AP in treatment of femoral shaft nonunion after intramedullary nail fixation in recent years were widely reviewed and analyzed. Results The AP has been successfully applied to femoral shaft nonunion after intramedullary nail fixation since 1997. According to breakage of the previous nailing, AP is divided into two categories: AP with retaining the previous intramedullary nail and AP with exchanging intramedullary nail. AP is not only suitable for simple nonunion, but also for complex nonunion with severe deformity. Compared with exchanging intramedullary nail, lateral plate, and dual plate, AP has less surgical trauma, shorter healing time, higher healing rate, and faster returning to society. However, there are still some problems with the revision method, including difficulty in bicortical screw fixation, lack of anatomic plate suitable for femoral shaft nonunion, and lack of postoperative function and quality of life assessment. Conclusion Compared with other revision methods, AP could achieve higher fracture healing rate and better clinical prognosis for patients with femoral shaft nonunion. However, whether patients benefit from AP in terms of function and quality of life remain uncertain. Furthermore, high-quality randomized controlled clinical studies are needed to further confirm that AP are superior to the other revision fixations.

Abstract
In the last two decades bisphosphonates (BP) has become the mainstream therapy for osteoporosis and the benefit in reducing the incidence of fractures has been well demonstrated in several studies, together with the drug long term (5-10 years) efficacy and safety. A complication of the long-term use of bisphosphonates is a low-energy stress fractures located in the sub-trochanteric region and the femoral shaft called atypical femur fracture (AFF). These stress fractures can be seen on plain radiographs as simple transverse patterns, with unicortical beaking and hypertrophy of the diaphyseal lateral cortex. Usually a localized thigh pain in the prodromal phase may precede the fracture by months. The current surgical treatment of choice for AFFs is intramedullary nailing (IMN). However, the treatment of AFFs is associated with a higher rate of intra-operative and post-surgical complications. This is related to anatomical e biomechanical reasons. Iatrogenic fractures, deformities, medial gap opening, eccentric position of the distal nail tip with anterior cortex perforation, delayed or non-union are frequent complications of this procedure and healing rate of AFFs. The average healing time of almost 8 months for AFFs appeared to be longer than that for typical femoral fractures, which heal at an average of 3-6 months. The purpose of this study is to analyze the different surgical devices and techniques and to advance some considerations that can be useful to diminish the rate of failure and/or complications in the treatment of AFFs in both oncologic and osteoporotic patients.

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
BACKGROUND The treatment of subtrochanteric fracture nonunion is challenging. Although revision with either an intramedullary or extramedullary device had been advocated with acceptable results, complications that require secondary procedures still arise. The use of an intramedullary device with augmentation plate fixation is a well-known approach for femoral or tibial diaphyseal nonunion. However, this approach has not previously been reported for subtrochanteric fracture nonunion. MATERIALS AND METHODS A series of 21 cases of subtrochanteric fracture nonunion treated with an intramedullary device in combination with augmentation side plating were collected and retrospectively reviewed after an average of 18 months of followup. Fourteen patients with a prior well-fixed intramedullary device were treated with side plating and bone grafting. Seven patients underwent revision nailing in addition to side plating and bone grafting. RESULTS All fractures united well without major complication. The average time to union was 7.1 months. CONCLUSION The use of an intramedullary device with augmentation plate fixation is a reliable and decisive procedure for treating subtrochanteric fracture nonunion that produces satisfactory results with a low complication rate.

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

J Orthop Surg Res 2018; 13:180. [PMID: 30029657 PMCID: PMC6054735 DOI: 10.1186/s13018-018-0886-y] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/19/2018] [Accepted: 07/06/2018] [Indexed: 12/21/2022] Open
Abstract
Background Currently, there remains a lack of consensus regarding factors predictive of complication such as re-nonunion after primary revision in femoral shaft nonunion subsequent to failed intramedullary nailing (IMN). A better understanding of prognostic factors could potentially reduce the risk of re-nonunion happening and allow patients to maximize their recovery in the most expeditious manner. Our study aims to identify risk factors in the development of re-nonunion after primary revision inclusive of exchanging reamed nailing (ERN) and augmentative compression plating (ACP) with IMN in situ for femoral shaft nonunion subsequent to failed IMN. Methods A retrospective study was performed for 63 cases (61 patients) of femoral shaft nonunion subsequent to failed IMN, who were made primary revision with either ERN or ACP from June 2007 to June 2015. The following set of variables was selected based on the speculation that they would contribute to the outcome: sex (male or female), age, body mass index(BMI), smoking, alcohol abuse, cause of injury, fracture type, type of IMN (antegrade or retrograde), use of IMN locking screws(dynamic or static), site of nonunion, primary nonunion time, pathological type of nonunion, bone defect (mm), primary revision method (ERN or ACP), and adjuvant autogenous bone grafting (ABG) (yes or no). Univariate analysis and multiple regression were used to identify risk factors in the development of re-nonunion after primary revision with either ERN or ACP for femoral shaft nonunion subsequent to failed IMN. The minimum follow-up time was 1.5 years (standard deviation [SD] = 1.2, range 1.5–8 years). Results Of 63 cases (61 patients) of femoral shaft nonunion subsequent to failed IMN, primary revision with ERN was performed in 33 (52.4%) cases and primary revision with ACP was performed in 30 (47.6%) cases. Adjuvant ABG procedure was undertaken in 39 (61.9%) cases during primary revisions. Re-nonunion was diagnosed as in 18 (28.6%) cases after primary revision with either ERN or ACP. There was a significant difference in time to union between patients treated with primary ERN and those with primary ACP (log-rank, p = 0.006). Furthermore, the difference was also statistically significant between patients with adjuvant ABG procedure and those without it (log-rank, p = 0.009). The relative risk factors included smoking, BMI, site of nonunion, bone defect, primary revision method, and adjuvant ABG procedure. However, primary revision method and adjuvant ABG procedure were shown to be two independent risk factors in multiple logistic regression analysis. Conclusions Patients with excessive tobacco use, BMI ≥ 30 kg/m2, bone defect ≥ 5 mm, primary revision with ERN, and no adjuvant ABG procedure had a higher likelihood of developing re-nonunion. Of these risk factors, primary revision with ERN and no adjuvant ABG procedure were two strongest risk factors.

Abstract
AIM To analyze the literature on efficacy of dynamamization vs exchange nailing in treatment of delayed and non-union femur fractures.
METHODS Ultimately, 31 peer-reviewed articles with 644 exchanged nailing patients and 131 dynamization patients were identified and analyzed. The following key words were inputted in different combinations in order to search the field of publications in its entirety: “non-union”, “delayed union”, “ununited”, “femur fracture”, “femoral fracture”, “exchange nailing”, “dynaiz(s)ation”, “secondary nailing”, “dynamic”, “static”, and “nail revision”. The initial search yielded over 150 results, and was refined based on the inclusion criteria: Only studies reporting on humans, non-unions and delayed unions, and the usage of exchange nailing and/or dynamization as a secondary treatment after failed IM nailing. The resulting 66 articles were obtained through online journal access. The results were filtered further based on the exclusion criteria: No articles that failed to report overall union rates, differentiate between success rates of their reported techniques, or articles that analyzed less than 5 patients.
RESULTS Exchange nailing lead to fracture union in 84.785% of patients compared to the 66.412% of dynamization with statistically comparable durations until union (5.193 ± 2.310 mo and 4.769 ± 1.986 mo respectively). Dynamically locking exchange nails resulted in an average union time of 5.208 ± 2.475 mo compared to 5.149 ± 2.366 mo (P = 0.8682) in statically locked exchange nails. The overall union rate of the two procedures, statically and dynamically locked exchange nailing yielded union rates of 84.259% and 82.381% respectively. Therefore, there was no significant difference between the different locking methods of exchange nailing for union rate or time to union at a significance value of P < 0.05. The analysis showed exchange nailing to be the more successful choice in the treatment of femoral non-unions in respect to its higher success rate (491/567 EN, 24/57 dynam, P < 0.0001). However, there was no significant difference between the success rates of the two procedures for delayed union fractures (25/27 EN, 45/55 dynam, P = 0.3299). Nevertheless, dynamization was more efficient in the treatment of delayed unions (at rates comparable to exchange nailing) than in the treatment of non-unions.
CONCLUSION In conclusion, after examination of factors, dynamization is recommended treatment of delayed femur fractures, while exchange nailing is the treatment of choice for non-unions.

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
INTRODUCTION The treatment options for nonunions of infraisthmal femoral shaft fractures after internal fixation are controversial. Methods such as exchanging an existing nail with a nail of a larger size, dynamization, removal of the nail followed by plating, and bone grafting have all been reported. Among those options, exchange nailing seems to be the most popular choice. In this study, a Poller screw, or an additional interlocking screw, was used in conjunction with exchange intramedullary nailing. The purpose of this study was to evaluate the effectiveness of treating femoral shaft nonunions using insertion of a Poller screw or an additional interlocking screw in conjunction with intramedullary nail fixation. MATERIALS AND METHODS This study included 18 patients who presented with nonunion of femur shaft fractures after internal fixation at the infraisthmal level. These patients included 13 men and 5 women, with a mean age of 46.8 years (range 15-78 years). The mean postsurgical period of nonunion was 7.8 months (range 6-12 months). The patients were classified into two groups: the atrophic nonunion group and the hypertrophic nonunion group. In all patients, nailing was enhanced with a Poller screw or additional interlocking screws. All patients were followed up with plain film examinations and were assessed for their functional recovery status to determine the osseous union conditions. RESULTS All 18 patients achieved postoperative bony union after a mean time of 7.5 months (range 3-12 months), and all patients were able to walk with full weight-bearing and without pain within 3 months. There were no significant complications, such as broken hardware, implant back-outs, axial or rotational malalignments, or deep infections. CONCLUSION Poller screws and additional interlocking screws, along with intramedullary nailing exchange, may be an effective and reliable alternative for treating infraisthmal femoral shaft nonunions.

Minimally invasive plate augmentation in the treatment of long-bone non-unions. Arch Orthop Trauma Surg 2017; 137:1523-1528. [PMID: 28821936 DOI: 10.1007/s00402-017-2773-0] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/01/2017] [Indexed: 10/19/2022]
Abstract
INTRODUCTION Exchange nailing is most acceptable for treating hypertrophic non-union of the long bones, requiring the removal of previously fixed implant. However, its main effect of mechanical stabilization is controversial in non-isthmal area. We hypothesized that minimally invasive plate augmentation over the non-union site may have a better option, without the need of bone grafting or removing pre-existing implants. MATERIALS AND METHODS Seventeen patients with hypertrophic non-union of the long bones between 2010 and 2014 on radiography who previously underwent intramedullary (IM) nailing or plate osteosynthesis for long-bone fractures were included. A locking compression plate was inserted with at least three mono- or bicortical screws at each proximal and distal segment. Broken or loosened interlocking screws of IM nail were simultaneously re-fixed. Fracture site exposure, pre-fixed implant removal, and bone grafting were not performed. We investigated whether union occurred and analyzed functional outcomes and complications. RESULTS Eleven femoral and six tibial non-unions were prospectively included. In the pre-existing implants, 13 nails and 4 plates were found. All cases achieved union at a mean 22.7 weeks. One case of superficial infection was managed with oral antibiotics. Deep infection or implant failure did not occur. CONCLUSIONS Minimally invasive plate augmentation can achieve additional stability and promote healing of hypertrophic non-union of the long bones. When indicated, this technique is the least invasive alternative to exchange nailing and reduces surgical risks in the treatment of diaphyseal non-union.

Abstract
PURPOSE Fracture nonunion is a common problem for today's orthopaedic surgeon. However, many techniques are currently available for the treatment of long-bone nonunion. This video demonstrates the use of iliac crest bone graft and plate stabilization in the setting of a hypertrophic femoral nonunion. METHODS Treatment of femoral nonunion after intramedullary nail fixation using compression plating and bone grafting is a reliable technique for reducing pain, improving function, and achieving radiographic union. Furthermore, the use of autologous bone graft, in particular iliac crest bone graft, has provided reliable clinical results. RESULTS In this video, we present the case of a hypertrophic femoral nonunion treated with supplemental bone grafting in addition to plate and screw fixation. CONCLUSIONS Although femoral nonunions are a relatively rare occurrence, they can be reasonably treated using stabilization and supplemental bone grafting. Iliac crest bone graft provides for excellent results when used for treatment of a fracture nonunion.

Biomechanical Property of a Newly Designed Assembly Locking Compression Plate: Three-Dimensional Finite Element Analysis. JOURNAL OF HEALTHCARE ENGINEERING 2017; 2017:8590251.

Abstract
In this study, we developed and validated a refined three-dimensional finite element model of middle femoral comminuted fracture to compare the biomechanical stability after two kinds of plate fixation: a newly designed assembly locking compression plate (NALCP) and a locking compression plate (LCP). CT data of a male volunteer was converted to middle femoral comminuted fracture finite element analysis model. The fracture was fixated by NALCP and LCP. Stress distributions were observed. Under slow walking load and torsion load, the stress distribution tendency of the two plates was roughly uniform. The anterolateral femur was the tension stress area, and the bone block shifted toward the anterolateral femur. Maximum stress was found on the lateral border of the number 5 countersink of the plate. Under a slow walking load, the NALCP maximum stress was 2.160e+03 MPa and the LCP was 8.561e+02 MPa. Under torsion load, the NALCP maximum stress was 2.260e+03 MPa and the LCP was 6.813e+02 MPa. Based on those results of finite element analysis, the NALCP can provide adequate mechanical stability for comminuted fractures, which would help fixate the bone block and promote bone healing.

Abstract
BACKGROUND The purpose of this study was to analyze factors that affect healing time after operative treatment of complete femoral fractures associated with long-term use of bisphosphonates. In particular, we sought to determine surgically controllable factors related to fracture-healing time. METHODS Ninety-nine consecutive patients (109 fractures) who had been surgically treated for a complete atypical femoral fracture were enrolled. All patients had a documented history of bisphosphonate therapy at the time of presentation, with an average duration of 7.4 ± 3.5 years (range, 3 to 20 years). Baseline demographic data, characteristics of the fracture and surgery, and radiographic findings including femoral neck-shaft angle, coronal and sagittal bowing of the femur, and thickness of the femoral cortex were examined. Univariate and multivariate logistic regression analyses were performed to identify predictive factors associated with delayed union or nonunion. RESULTS Of the 109 fractures, 76 (69.7%) showed osseous union within 6 months after the index surgery and were assigned to the successful healing group. The remaining 33 fractures (30.3%), which showed delayed union or nonunion, were assigned to the problematic healing group. There were differences in body mass index (BMI), bisphosphonate therapy duration, and the rate of prodromal symptoms between the 2 groups. Supra-isthmic fracture location, femoral bowing of ≥10° in the coronal plane, and a lateral/medial cortical thickness ratio of ≥1.4 were predictive of problematic healing but were uncontrollable factors. Iatrogenic cortical breakage around the fracture site as well as a ratio of ≥0.2 between the remaining gap and the cortical thickness on the anterior and lateral sides of the fracture site were controllable predictive factors associated with problematic healing. CONCLUSIONS Intramedullary nailing without cortical breakage around the fracture site and decreasing the anterior and lateral fracture gaps (avoidance of distraction) as much as possible are recommended to reduce healing time in complete femoral fractures associated with long-term use of bisphosphonates. LEVEL OF EVIDENCE Therapeutic Level IV. See Instructions for Authors for a complete description of levels of evidence.

Abstract
Objective To explore the indications and efficacy of augmentative locking compression plate (LCP) or less invasive stabilization system (LISS)with autogenous bone grafting (BG) in treating distal femoral nonunion subsequent to failed retrograde intramedullary nailing (RIN). Methods A retrospective study was performed for 21 patients with distal femoral nonunion subsequent to failed RIN, who received therapy with either augmentative LCP (n = 11) or LISS with autogenous BG (n = 13). Operation time, time to union, union rate, time to renonunion, complication rate and SF-36 scores a year after hardware removal were compared between the two groups. Results The bone union occurred in 13/13 (100%) cases in augmentative LISS group versus 9/11 (81.8%) cases in augmentative LCP group [odds ratio (OR) = 3.21, 95% confidence interval (CI) 0.7–13]. Time to union, time to renonunion, complication rate of the augmentative LCP group were significantly more than that of the augmentative LISS with autogenous BG group (p = 0.023, p = 0.021 and p = 0.033). No significant difference was found in the average operation time of two groups (p = 0.121). At the follow-up a year after hardware removal, statistically significant HRQOL improvement in the augmentive LISS group was measured at the level of pain (p = 0.003) and general health perception (p = 0.011), as compared to the augmentive LCP group. Conclusions We suggest augmentative LCP, for distal femoral nonunios after RIN, may be optimal for that of typeAO33A fractures, whereas augmentative LISS for that of typeAO33C fractures more.

Abstract
An evidence-based description of aseptic tibial and femoral diaphyseal nonunions without segmental defects is based on a systematic search of MEDLINE. Aseptic nonunion of the femoral or tibial diaphysis without segmental defects and with an in situ nail, treated with reamed exchange nailing or augmentative plating and bone grafting, has consistently high union rates. Aseptic nonunion without segmental defects and with in situ plate and screw fixation is best managed with revision plate and screw fixation and autogenous bone graft. Various techniques and methods of biological stimulation have relatively high union rates.

Abstract
The aim of this study was to identify risk factors for failure of exchange nailing for femoral diaphyseal fracture non-unions. The study cohort comprised 40 patients with femoral diaphyseal non-unions treated by exchange nailing, of which six were open injuries. The median time to exchange nailing from primary fixation was 8.4 months. The main outcome measures were union, number of secondary fixation procedures required to achieve union and time to union. Multiple causes for non-union were found in 16 (40%) cases, with infection present in 12 (30.0%) patients. Further surgical procedures were required in nine (22.5%) cases, one of whom (2.5%) required the use of another fixation modality to achieve union. Union was ultimately achieved with exchange nailing in 34/37 (91.9%) patients. The median time to union after the exchange nailing was 9.4 months. Cigarette smoking and infection were risk factors for failure of exchange nailing. Multivariate analysis found infection to be the strongest predictor of exchange failure (p<0.05). Exchange nailing is an effective treatment for aseptic femoral diaphyseal fracture non-union. However, 50% of patients undergoing exchange nailing in the presence of infection required at least one further procedure. It is important to counsel patients of this so that they can plan for it and do not consider that the first exchange operation has failed.

Abstract
PURPOSE To review the outcomes of 102 consecutive patients who underwent fixation for nonunion of extremities. METHODS Medical records of 71 men and 31 women aged 16 to 82 (mean, 45; standard deviation [SD], 19) years who underwent fixation for nonunion of the upper (n=31) and lower (n=71) extremities were reviewed. The nonunion types included oligotrophic (n=47), hypertrophic (n=22), atrophic (n=17), defect (n=12), and comminuted (n=4). 13 of the nonunions were infected. 10 patients had concomitant injuries of the brain (n=2), abdomen (n=5), chest (n=1), and spine (n=2). 43 patients were smokers, and 19 had diabetes mellitus. 80 patients had had previous surgery, and 3 had undergone previous radiotherapy. The mean time from injury to nonunion surgery was 19 (SD, 25.6; range, 6-180) months. Outcome measures included bone union, ability to return to original work, pain, gait, and loss of range of motion. RESULTS The mean follow-up period was 26.6 (SD, 19.9; range, 8-121) months. 100 patients achieved bone union. 83 of them achieved bone union after a single surgery in a mean of 5.6 (SD, 2.9) months. The remaining 17 patients underwent multiple surgeries, 13 of whom had infected nonunions. Two patients did not achieve bone union. Of 64 patients who had work, 47 returned to their original work and 17 did not. Outcome was unsatisfactory in 5 patients who had persistent pain and/or no improvement in gait. CONCLUSION Bone union is not necessarily associated with adequate recovery of function.

Abstract
PURPOSE We assessed indications and outcomes of exchange nailing and augmentation plating for femoral shaft nonunion following femoral nail failure. METHODS We retrospectively reviewed the records of 21 consecutive patients with femoral shaft nonunion treated with femoral nailing from August 2008 to June 2013. Nonunion cases with infection were excluded from this study. The study population consisted of nine men and 12 women, with an average age of 40 (range 21-61) years. All patients received internal fixation using exchange nailing and an augment plate coupled with decortication and bone graft. RESULTS All patients in our study obtained osseous union with a mean time of six (range four to12) months. Mean operation time was three hours (range two to five hours), and mean blood loss was 800 ml (range 500-950 ml). There were no postoperative complications. At the last follow-up, all patients could flex their knees > 110°. CONCLUSIONS Exchange nailing and augment plating coupled with decortication and bone graft is an effective treatment option for femoral shaft nonunion and has more indications and higher union rate than the popular exchange nailing treatment.

Abstract
INTRODUCTION Though augmentation plating (AP) with decortication and bone grafting (BG) reportedly has excellent outcomes for femoral shaft nonunions, there are no established indications of AP with decortication and BG. The purpose of this study was to evaluate the results of AP with decortication and autogenous BG for femoral shaft nonunions, focussing on the indications of AP with decortication and BG. METHODS Thirty-nine patients treated with AP combined with decortication and BG for femoral shaft nonunions after femoral nail failure between November 1996 and October 2010 were retrospectively reviewed. Indications of AP with decortication and BG at the time of surgery and outcomes (bony union) were evaluated. RESULTS The mean follow-up duration was 24.8 months (range 12-81 months). Thirty-eight (97%) of 39 femoral shaft nonunions achieved bony union. One incompliant patient showed screw breakage, which was healed uneventfully with subsequent cast application. The mean time to union was 6.1 months (range 3-16 months). Primary indications at the time of surgery were nonisthmal femoral nonunions in 17 patients, isthmal nonunions in 10 patients (cortical bone defect in five and widened canal in five), failed exchange nail in seven patients, nonunions with malrotation in two patients and difficult removal in three patients. CONCLUSIONS AP with decortication and autogenous BG is a good option for nonisthmal femoral shaft nonunions, such as supra-isthmal and infra-isthmal nonunions. In addition, this option is useful for selected cases of isthmal femoral shaft nonunions in which failure of exchange nailing is expected due to lack of a tight fit between the new larger nail and femoral cortices.

Abstract
Introduction Heterotopic ossification is a rare complication of musculoskeletal injuries, characterized by bone growth in soft tissues. Percutaneous antegrade intramedullary nailing represents the ‘gold standard’ for the treatment of femur shaft fractures. Minor bone growth is frequently seen around the proximal end of reamed femoral nails (so-called ‘callus caps’), which are asymptomatic and lack a therapeutic implication. The occurrence of excessive, symptomatic heterotopic ossification around the entry site of an antegrade femoral nail is rarely described in the literature. Case presentation We present the case of a 28-year-old Caucasian woman who developed extensive heterotopic ossification around the reaming seeds of a reamed femoral nail. She developed severe pain and significantly impaired range of motion of the hip joint, requiring revision surgery for heterotopic ossification resection and adjunctive local irradiation. She recovered full function of the hip and remained asymptomatic at her two-year follow-up appointment. Conclusions Severe heterotopic ossification represents a rare but potentially detrimental complication after percutaneous femoral nailing of femur shaft fractures. Diligent care during the reaming procedure, including placement of a trocar to protect from osteogenic seeding of the soft tissues, may help decrease the risk of developing heterotopic ossification after reamed antegrade femoral nailing.
