Shih CY, Kor CT, Hsieh CP, Chen CL, Lo YC. Does nail size or difference between canal and nail diameter influence likelihood of union or time to union of femoral shaft fractures treated with intramedullary nailing? A retrospective cohort study. BMC Musculoskelet Disord 2022; 23:826. [PMID: 36045444 PMCID: PMC9429295 DOI: 10.1186/s12891-022-05781-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/18/2022] [Accepted: 08/25/2022] [Indexed: 11/26/2022] Open
Abstract
Background This study aims to determine whether nail size or the difference between canal and nail diameter (CN difference) affects the union rate and time of femoral shaft fracture treated with an interlocking intramedullary nail (IMN). Methods This was a retrospective review of 257 patients with femoral shaft fractures treated with IMN at a tertiary trauma medical center. All the IMN inserted were the same (Stryker T2 Femoral Nail). The patients were divided into groups based on nail size (10-, 11-, 12-, or 13-mm) and CN difference (< 1, 1–2, or > 2 mm), and union rate and time to union were compared. Results The 10-, 11-, 12-, and 13-mm groups based on nail size had 113, 74, 54, and 16 patients, respectively. The overall union rate was 97% (257/265). No significant differences in union rate or time to union were observed among these 4 groups. The groups based on CN differences of < 1-, 1 to 2, and > 2 mm comprised 143, 79, and 35 patients, respectively. Again, no significant differences were noted in union rate or mean time to union among the groups. Conclusions Similar union rate and time to union were observed, regardless of nail size or CN difference. This finding indicates that most simple femoral shaft fractures can be treated with a standard, reamed 10-mm IMN. A larger nail insertion is unnecessary and presents more risks; comparatively, the use of a small nail with less reaming is simpler, requires shorter operative times, results in less blood loss, and is less expensive.

Reamed versus unreamed intramedullary nailing for the treatment of femoral shaft fractures among adults: A meta-analysis of randomized controlled trials. J Orthop Sci 2022; 27:850-858. [PMID: 34303590 DOI: 10.1016/j.jos.2021.03.022] [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: 10/23/2020] [Revised: 02/03/2021] [Accepted: 03/17/2021] [Indexed: 11/25/2022]
Abstract
BACKGROUND The purpose of this meta-analysis is to compare the merits and drawbacks between reamed intramedullary nailing (RIN) and unreamed intramedullary nailing (URIN) among adults. METHODS We comprehensively searched PubMed, MEDLINE database through the PubMed search engine, Google Scholar, Cochrane Library, Embase, VIPI (Database for Chinese Technical Periodicals), and CNKI (China National Knowledge Infrastructure) from inception to March 2020. Outcomes of interest included nonunion rates, implant failure rates, secondary procedure rates, blood loss, acute respiratory distress syndrome (ARDS) rates, and pulmonary complications rates. RESULTS Eight randomized controlled trials were included. The result of nonunion rates shows that the nonunion rate is significantly lower in the RIN group (RR = 0.20, 95% CI = 0.09-0.48, Z = 3.63, P = 0.0003). There were no significant differences for the risk of implant failure rates (RR = 0.55, 95% CI = 0.18-1.69, Z = 1.04, P = 0.30). The secondary procedure rates were significantly lower in the RIN group (RR = 0.28, 95% CI = 0.12-0.66, Z = 2.91, P = 0.004). The result shows that the blood loss of URIN group is significantly lower (RR = 145.52, 95% CI = 39.68-251.36, Z = 2.69, P = 0.007). The result shows that there was no significant difference in the ARDS rates (RR = 1.53, 95% CI = 0.37-6.29, Z = 0.59, P = 0.55) and the pulmonary complications rates between RIN group and URIN group (RR = 1.59, 95% CI = 0.61-4.17, Z = 0.94, P = 0.35). CONCLUSIONS Reamed intramedullary nailing would lead to lower nonunion rate, secondary procedure rate and more blood loss. Unreamed intramedullary nailing is related to a higher nonunion rate, secondary procedure rate and less blood loss. No significant difference is found in implant failure rate, ARDS rate and pulmonary complication rate between the two groups.

A biomechanical study. Injury 2021; 52 Suppl 4:S61-S70. [PMID: 33707035 DOI: 10.1016/j.injury.2021.02.062] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/14/2020] [Revised: 02/15/2021] [Accepted: 02/18/2021] [Indexed: 02/02/2023]
Abstract
INTRODUCTION Intramedullary nailing is generally accepted as the first choice for the treatment of diaphyseal fractures of femur and tibia, with a gradual incease in the use of unreamed nails. Different studies during last years show controversial outcomes. Some authors strongly favor unreamed nailing, but most of the authors conclude that reamed nailing have proved to be more successful. MATERIAL AND METHODS This study simulates unreamed intramedullary nailing of four femoral and three tibial fracture types by means of Finite Element (FE) models, at early postoperative stages with a fraction of physiological loads, in order to determine whether sufficient stability is achieved, and if the extent of movements and strains at the fracture site may preclude proper consolidation. RESULTS The behavior observed in the different fracture models is very diverse. In the new biomechanical situation, loads are only transmitted through the intramedullary nail. Mean relative displacement values of fractures in the femoral bone range from 0.30 mm to 0.82 mm, depending on the fracture type. Mean relative displacement values of the tibial fractures lie between 0.18 and 0.62 mm, depending on the type of fracture. Concerning mean strains, for femoral fractures the maximum strains ranged between 12.7% and 42.3%. For tibial fractures the maximum strains ranged between 10.9% and 40.8%. CONCLUSIONS The results showed that unreamed nailing provides a very limited mechanical stability, taking into account that analyzed fracture patterns correspond to simple fracture without comminution. Therefore, unreamed nailing is not a correct indication in femoral fractures and should be an exceptional indication in open tibial fractures produced by high-energy mechanism.

Safety and efficacy of a novel cephalomedullary nail femoral shaft fractures: a retrospective observational cohort in 33 patients. Patient Saf Surg 2020; 14:44. [PMID: 33292398 PMCID: PMC7718683 DOI: 10.1186/s13037-020-00269-z] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/28/2020] [Accepted: 10/13/2020] [Indexed: 12/30/2022] Open
Abstract
BACKGROUND Despite advances in femoral shaft fracture fixation, the nonunion rate remains relatively high; and there is limited data on the efficacy and failure rate of specific implants. A novel cephalomedullary nail provides the ability to treat femur shaft fractures in isolation, with associated ipsilateral femur injuries, and provides various options for proximal and distal fixation exists on the market; but literature remains limited on the safety and efficacy of this implant. The aim of this study is to evaluate the early failure rate of this cephalomedullary nail, while comparing the nonunion rate to what is currently presented in the literature. This study is the first of its kind in evaluation of a specific implant for treatment of femoral shaft fractures and ipsilateral pathology. METHODS Patients over 18 years of age, with traumatic femur shaft fractures, treated with this particular cephalomedullary nail and available for a minimum of 3-month follow-up were included for analysis. Data was collected by retrospective chart review and review of existing radiographs. Demographic data, injury details, AO/OTA fracture classification, and implant details were recorded for each patient. Primary outcome measured was implant failures (screw or nail breakage). Secondary outcomes measured included malunion, nonunion, deep infection, post-operative complications, and need for reoperation. RESULTS Of the 33 patients included for analysis, 1 patient went on to non-union. There were no cases of implant failure. The single nonunion was a high-energy mechanism, open fracture, and higher level AO/OTA classification. The remaining 32 reached radiographic union at 3 months. CONCLUSION The nonunion rate of this novel cephalomedullary nail is comparable to what is reported in the literature. This nail is a safe and effective implant to treat femoral shaft fractures with a variety of ipsilateral femoral shaft injuries and reliably leads fracture union. Further studies are needed analyzing implant failure and comparing specific implants.

Structural alterations and inflammation in the heart after multiple trauma followed by reamed versus non-reamed femoral nailing. PLoS One 2020; 15:e0235220.

Abstract
BACKGROUND Approximately 30,000 patients with blunt cardiac trauma are recorded each year in the United States. Blunt cardiac injuries after trauma are associated with a longer hospital stay and a poor overall outcome. Organ damage after trauma is linked to increased systemic release of pro-inflammatory cytokines and damage-associated molecular patterns. However, the interplay between polytrauma and local cardiac injury is unclear. Additionally, the impact of surgical intervention on this process is currently unknown. This study aimed to determine local cardiac immunological and structural alterations after multiple trauma. Furthermore, the impact of the chosen fracture stabilization strategy (reamed versus non-reamed femoral nailing) on cardiac alterations was studied. EXPERIMENTAL APPROACH 15 male pigs were either exposed to multiple trauma (blunt chest trauma, laparotomy, liver laceration, femur fracture and haemorrhagic shock) or sham conditions. Blood samples as well as cardiac tissue were analysed 4 h and 6 h after trauma. Additionally, murine HL-1 cells were exposed to a defined polytrauma-cocktail, mimicking the pro-inflammatory conditions after multiple trauma in vitro. RESULTS After multiple trauma, cardiac structural changes were observed in the left ventricle. More specifically, alterations in the alpha-actinin and desmin protein expression were found. Cardiac structural alterations were accompanied by enhanced local nitrosative stress, increased local inflammation and elevated systemic levels of the high-mobility group box 1 protein. Furthermore, cardiac alterations were observed predominantly in pigs that were treated by non-reamed intramedullary reaming. The polytrauma-cocktail impaired the viability of HL-1 cells in vitro, which was accompanied by a release of troponin I and HFABP. DISCUSSION Multiple trauma induced cardiac structural alterations in vivo, which might contribute to the development of early myocardial damage (EMD). This study also revealed that reamed femoral nailing (reamed) is associated with more prominent immunological cardiac alterations compared to nailing without reaming (non-reamed). This suggests that the choice of the initial fracture treatment strategy might be crucial for the overall outcome as well as for any post-traumatic cardiac consequences.

[PMID: 31610947 DOI: 10.1016/j.injury.2019.10.010] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/14/2019] [Revised: 08/07/2019] [Accepted: 10/03/2019] [Indexed: 02/02/2023]
Abstract
INTRODUCTION Controversy exists regarding the use of reamed interlocking nailing in femoral shafts with extremely narrow medullary canals (diameter ≤ 9 mm). The aims of this study were to (1) investigate the association of age and sex on femoral canal diameter in patients with a simple femoral shaft fracture and (2) compare the outcomes and complications of interlocking nailing between wide and extremely narrow intramedullary canals. PATIENTS AND METHODS For the purposes of this retrospective cohort study, consecutive patients with simple femoral shaft fractures were recruited between January 2009 and December 2016. The patient demographic data were analyzed. Then, fractures treated with interlocking nailing were divided into the wide group (canal diameter > 9 mm) and narrow group. The primary outcome was union rate, and the secondary outcomes were complications such as thermal necrosis, fat embolism syndrome, iatrogenic fracture, and implant failure. RESULTS This study included 340 femoral shaft fractures. The average canal diameter was 9.97 ± 1.79 mm, with significantly wider canals in men than in women. Overall, 289 of the patients had undergone interlocking nail fixation, and a similar union rate and complications were noted between the wide canal and narrow canal groups, with the exception of the incidence of iatrogenic fracture. CONCLUSIONS Femoral shaft fractures associated with extremely narrow medullary canals are more common in women than in men. There was a similar union rate found when using interlocking nailing in a femoral shaft fracture in cases with extremely narrow and wider canals. Iatrogenic fracture is the only significant risk when using interlocking nailing in femoral shafts with extremely narrow canals.

Abstract
Objective: Osteosynthesis with intramedullary nailing is considered the method of choice to treat diaphyseal femur fractures in adults. The objective of this retrospective study was to evaluate the bone healing time and incidence of infection in patients with diaphyseal femur fractures treated surgically with retrograde and antegrade intramedullary nailing. Methods: The medical records of 123 patients from two university hospitals dated 2011-2013 were evaluated, with 126 diaphyseal femur fractures having been found. The most frequent treatment was antegrade intramedullary nailing (51%), of which 38% involved reaming (n=25). Results: We found evidence of 92% healed fractures at 12 months postoperatively. Complications included chronic osteomyelitis in one patient and femoral neck fracture in another patient, both after reamed antegrade nailing. Pyoarthritis of the knee associated with osteomyelitis affected two patients after reamed retrograde nailing and one patient after unreamed retrograde nailing. Conclusion: We did not observe a significant difference in bone healing rates with the use of reamed or unreamed antegrade or retrograde nailing. Complications included the presence of infection with an incidence similar to that reported in the literature, and of particular significance, unrelated to the type of approach. Level of evidence III, Retrospective comparative study.

Abstract
Background This study retrospectively evaluated the clinical outcomes of intramedullary nailing of femoral shaft fractures with third fragments and analyzed the risk factors for delayed union. Methods Retrospective analyses involving 51 patients who underwent intramedullary nailing of femoral shaft fractures with third fragments (AO classification type B, 35 cases; type C, 16 cases) were conducted. Delayed union was defined as either more than 10 months required for callus formation in more than three of the four cortical bone surfaces observed in the frontal and lateral radiographic views or the requirement for additional surgery such as nail conversion or bone transplantation. Seventeen patients developed delayed union (D group). Thirty-four patients achieved bony union within 9 months (U group). The following background variables were compared between groups: age at the time of the injury; AO classification; ratio of open fracture; waiting period before surgery; rate of the infraisthmal fracture; diameter of the intramedullary nail; ratio of the intramedullary nail to the femur; length and displacement of the third fragment; and use of open reduction, poller screws, or dynamization. Results Significant differences were found between the D and U groups for age (32.2±14.1 vs. 25.3±9.6 years), open fracture ratio (35.3% vs. 11.8%), and displacement of the third fragment (13.7±6.4 vs. 9±6.3 mm). Multiple logistic regression analysis only identified displacement of the third fragment as a risk factor for delayed union (p=0.03; OR 1.13; 95% CI 1.01 to 1.26). Discussion Delayed union was observed in 17 cases (33.3%) after intramedullary nailing of femoral shaft fractures with third fragments. Displacement of the third fragment influenced delayed union. Level of evidence Level III.

Abstract
PURPOSE Nonunion is a highly morbid complication that exacerbates the pain, disability and financial burden of distal and diaphyseal femur fractures. This study examined the modern rates of healing, nonunion, and other complications requiring reoperation of different fixation methods for distal and diaphyseal femur fractures. METHODS A systematic review and meta-analysis of all records from PubMed, Embase and the Cochrane Review system was performed. Included studies had >20 acute, non-pathologic distal or diaphyseal femur fractures treated with primary internal fixation. Excluded were studies on abnormal patient/fracture populations, external fixation, or cement/bone graft use. RESULTS Thirty-eight studies with 2,829 femoral shaft fractures and 11 studies with 505 distal femur fractures were included. Distal fractures had a lower healing rate (86.6% vs. 93.7%) and a higher re-operation rate (13.4% vs 6.1%) than shaft fractures (p < 0.00001), primarily due to higher rates of mechanical failure (p < 0.00001). Nonunion was the most frequent complication, occurring in 4.7% of distal fractures and 2.8% of shaft fractures. There was no difference between plate and nail fixation of distal fractures in healing, nonunion, or other causes of re-operation. Shaft fractures developed nonunion in 6.6% of unreamed nails and 2.1% of reamed nails (p = 0.002). Nonunion occurred in 2.3% of antegrade nailed fractures and 1.5% of retrograde nailed fractures (p = 0.66). CONCLUSIONS Approximately one out of every eight distal fractures and one of every 16 shaft fractures requires re-operation. The most common cause of fixation failure is nonunion. Further research is needed to improve outcomes, particularly in distal femur fractures.

Abstract
A fundamental issue in clinical orthopaedics is the determination of when a fracture is united. However, there are no established "gold standards," nor standardized methods for assessing union, which has resulted in significant disagreement among orthopaedic surgeons in both clinical practice and research. A great deal of investigative work has been directed to addressing this problem, with a number of exciting new techniques described. This review provides a brief summary of the burden of nonunion fractures and addresses some of the challenges related to the assessment of fracture healing. The tools currently available to determine union are discussed, including various imaging modalities, biomechanical testing methods, and laboratory and clinical assessments. The evaluation of fracture healing in the setting of both patient care and clinical research is integral to the orthopaedic practice. Weighted integration of several available metrics must be considered to create a composite outcome measure of patient prognosis.

Abstract
BACKGROUND AND OBJECTIVE Intramedullary nailing is commonly used for treating femoral shaft fractures, one of the most common long bone fractures in adults. The reamed intramedullary nail is considered the standard implant for femoral fractures. This meta-analysis was performed to verify the superiority of reamed intramedullary nailing over unreamed intramedullary nailing in fractures of the femoral shaft in adults. Subgroup analysis of implant failure and secondary procedure was also performed. METHODS Electronic literature databases were used to identify relevant publications and included MEDLINE (Ovid interface), EMBASE (Ovid interface), and the Cochrane Central Register of Controlled Trials (CENTRAL; Wiley Online Library). The versions available on January 30, 2016, were utilized. Only human studies, which were designed as randomized controlled clinical trials, were included. Two authors independently evaluated the quality of original research publications and extracted data from the studies that met the criteria. RESULTS Around 8 randomized controlled trials involving 1078 patients were included. Reamed intramedullary nailing was associated with shorter time to consolidation of the fracture (SMD = -0.62, 95% CI = -0.89 to -0.35, P < 0.00001), lower secondary procedure rate (OR = 0.25, 95% CI 0.10-0.62, P = 0.003), lower nonunion rate (OR = 0.14, 95% CI = 0.05-0.40, P < 0.01), and lower delayed-union rate (OR = 0.19, 95% CI = 0.07-0.49, P < 0.01) compared to unreamed intramedullary nailing. The 2 groups showed no significant differences in risk of implant failure (OR = 0.50, 95% CI 0.14-1.74, P = 0.27), mortality risk (OR = 0.94, 95% CI 0.19-4.68, P = 0.94), risk of acute respiratory distress syndrome (ARDS; OR = 1.55, 95% CI 0.36-6.57, P = 0.55), or blood loss (SMD = 0.57, 95% CI = -0.22 to 1.36, P = 0.15). CONCLUSION Reamed intramedullary nailing is correlated with shorter time to union and lower rates of delayed-union, nonunion, and reoperation. Reamed intramedullary nailing did not increase blood loss or the rates of ARDS, implant failure, and mortality compared to unreamed intramedullary nailing. Therefore, the treatment of femoral fractures using reamed intramedullary nailing is recommended.

Abstract
PURPOSE To explore the possible surgical factors related with nonunion in femoral shaft fracture following intramedullary nailing. METHODS We retrospectively analyzed totally 425 patients with femoral shaft fracture in level I urban trauma center, including 254 males and 171 females, with an average age of 37.6 (ranging from 21 to 56) years old. The inclusion criteria included: (1) traumatically closed fracture of femoral shaft, with pre- operative films showing non-comminuted fracture, such as transverse fracture, oblique fracture or spiral fracture; (2) closed reduction and fixation with interlocking intramedullary nail at 3-7 days after trauma; (3) complete follow-up data available. The relationship between the following factors (fracture site, reduction degree, direction of nail insertion and nail size) and nonunion was studied. RESULTS The incidence of femoral nonunion was 2.8% in patients with closed simple fracture undergoing interlocking intrameduallary nailing, including 11 cases of hypertrophic nonunion. Nonunion was related significantly to distal fracture, unsatisfactory reduction and unreamed nail (p < 0.05). There was no significant difference between antegrade nail and retrograde nail (p > 0.05). CONCLUSIONS Nonunion in femoral shaft facture following interlocking intramedullary nailing is related to fracture site, fracture reduction and nail diameter. The choice of reamed nails or unreamed nails depends on the fracture site and reduction degree.

Abstract
OBJECTIVE To analyze the clinical-functional parameters and quality of life of patients undergoing minimally invasive surgical treatment for extra-articular fractures of the proximal phalanx, using an intramedullary screw (Acutrak(®)). METHODS Between January 2011 and September 2014, a prospective study was conducted on 41 patients (48 fingers) with unstable extra-articular fractures of the proximal phalanx, who underwent minimally invasive surgical treatment using an intramedullary screw (Acutrak(®)). These patients were evaluated 12 months after the surgery by means of the DASH quality-of-life questionnaire, VAS pain scale, measurement of range of motion (ROM, in degrees) and radiographic assessment. RESULTS All the patients achieved adequate reduction and consolidation of their fractures. There were statistically significant improvements in quality of life on the DASH scale, pain on the VAS scale and range of motion. CONCLUSION The minimally invasive technique for treating unstable extra-articular fractures of the proximal phalanx using an intramedullary screw (Acutrak(®)) is effective and safe, and it presents satisfactory clinical-functional results.

Abstract
INTRODUCTION A residual postoperative fracture gap between major bone fragments following intramedullary nailing of long-bone fractures is recognised as one of the major risk factors for delayed union and non-union. The most common method for reducing a fracture gap after nail insertion is through application of the backstroke technique. We introduce forward-striking as a new and simple technique that can be used to reduce fracture gaps during cephalomedullary or intramedullary nailing. PATIENTS AND METHODS The forward-striking technique was used in 20 patients with subtrochanteric or femoral shaft fractures and three patients with tibial shaft fractures who underwent cephalomedullary or intramedullary nailing at two university teaching hospitals between February 2013 and March 2014. RESULTS Bone union was achieved in all cases, with a mean time of 5.7 months (range, 3-9 months). No major complications, including, non-union, implant failure, or infection, were encountered during the follow-up period. CONCLUSION A forward-striking technique is simple, convenient, and highly efficient in terms of reducing fracture gaps during cephalomedullary or intramedullary nailing. The advantage of this technique is that it carries no risk of deforming the proximal interlocking screw, prevents excessive protrusion of the nail, and enables the lag screw to be placed into the optimal lag screw position relative to the femoral head at the time of cephalomedullary nailing. The forward-striking technique is particularly useful if no compression screw system is available.

Abstract
INTRODUCTION Intramedullary nailing (IMN) is the preferred treatment for femoral shaft fractures in adults. Although previous studies published good outcomes, some controversies remain. The purpose of this retrospective study was to identify factors that influence outcome after IMN for femoral shaft fractures. MATERIALS AND METHODS Between July 1998 and July 2013, we treated 230 patients with 248 femoral shaft fractures. Statistical analyses were performed to determine predictors of nonunion. The following set of variables was selected based on the speculation that they would contribute to the outcome: sex (male or female), smoking, obesity, polytrauma, fracture type, open fractures, Gustilo type, primary external fixation (EF) and reaming. RESULTS Initial fracture stabilization was performed by IMN in 161 (64.9%) and by EF in 87 (35.1%) fractures. There were no documented cases of deep infection. Nonunion was diagnosed in 27 patients with 28 fractures (11.3%). Factors affecting nonunion in the univariate analysis were Arbeitsgemeinschaft für Osteosynthesefragen/Orthopaedic Trauma Association (AO/OTA) fracture type (odds ratio [OR] 25.0; p<0.0001), Gustilo type (OR 0.64; p=0.0358), and EF (OR 0.42; p=0.0401). Multiple logistic regression analysis only identified AO/OTA fracture type (OR 22.0; p<0.0001) as a risk factor for nonunion. Fracture reaming did not change the outcome (OR 0.80; p=0.6073). A separate analysis showed that damage control EF was not a risk factor in polytrauma patients (OR 0.76; p=0.5825). CONCLUSIONS Fracture stabilisation with IMN is a good treatment option for femoral shaft fractures in adults. The purpose of this study was to evaluate risk factors of poor outcome after IMN of femoral shaft fractures. The present analysis revealed that there was no difference in the outcome whether the fracture was reamed or not. Univariate and multivariate analysis could only correlate AO/OTA fracture type with the occurrence of nonunion. Therefore, in this study, unreamed nailing and damage control EF were not associated with a negative outcome.

Abstract
UNLABELLED Bisphosphonates are commonly used in osteoporosis, but concerns have been raised about possible negative effects on fracture healing. We systematically reviewed the literature and found that bisphosphonates significantly prolong union times of distal radius fractures but not femoral fractures. The timing of bisphosphonate introduction does not affect fracture union time. INTRODUCTION Bisphosphonates are the most commonly prescribed drugs in patients suffering from and at higher risk of developing osteoporosis. However, concerns have been raised as to whether these drugs have a negative effect on fracture healing. The aim of this systematic review is to explore further these concerns. METHODS A literature review was performed in line with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. All relevant articles found via MEDLINE, Cochrane, CINAHL, EMBASE and Google Scholar were screened. Studies with information on bisphosphonates' effect on fracture healing in humans were included and systematically reviewed. RESULTS Patients with distal radius fractures on bisphosphonates had a significantly longer union time compared with controls, but not patients with femoral fractures. No correlation between timing of bisphosphonate introduction and union time for fractures was found. Although one study reported a higher humeral non-union associated with bisphosphonate introduction following the fracture, there was no evidence that bisphosphonate introduction, timing or dose resulted in a significant delay in union following other fractures. CONCLUSIONS This systematic review has shown that bisphosphonates significantly prolong union times of distal radius fractures. Some clinical findings are in contrast with preclinical studies highlighting the need to develop better animal models to study osteoporosis, treatment and fracture healing. There is also a need for more well-constructed studies looking at the clinical effect of bisphosphonate on fracture healing in a large number of patients. These robust studies need to look at union time and non-union rates as a function of duration and dose of different bisphosphonates in different upper and lower limb fractures.

Abstract
INTRODUCTION Compromised bone quality and the need for early mobilization still lead to high rates of implant failure in geriatric patients with distal femoral fractures. With the newest generation of polyaxial locking plates and the proven retrograde femoral nails today two minimally invasive surgical procedures have been established. Indications for both procedures overlap. This study attempts to define the strength and failure mode of both surgical procedures. MATERIALS AND METHODS A standardized fracture model was established to simulate an unstable AO/OTA 33-A3 fracture. Eight pairs of human cadaver femora (mean age 79 years, range 63-100 years) with compromised bone quality were used. Osteosyntheses with eight retrograde femoral nails and eight locking plates were randomly performed. A materials testing machine (Instron 5566) was used to perform cyclic stress tests according to a standardized loading protocol, up to a maximum load of 5,000 N. RESULTS All specimens survived loading of at least 2,500 N. Three nail and one plate construct survived a maximum load of 5,000 N. The mean compressive force leading to failure was 4,400 N (CI 4,122-4,678 N) for nail osteosynthesis and 4,429 N (CI 3,653-5,204 N) for plate osteosynthesis (p = 0.943). Proximal cutting out of the osteosynthesis was the most common reason for interruption in the nail and plate osteosyntheses. Significant differences between the retrograde femoral nail and plate osteosyntheses were seen under testing conditions for plastic deformation and stiffness of the constructs (p = 0.002 and p = 0.001, respectively). CONCLUSION Based on our results, no statements regarding the superiority of either of the devices can be made. Even though the load to failure values for both osteosyntheses were much higher than the loads experienced during normal walking; however, because only axial loading was applied, it remains unclear whether both osteosyntheses meet the estimated requirements for postoperative full weight-bearing for an average heavy patient with a distal femoral fracture.

Abstract
PURPOSE In case of stem loosening in periprosthetic femoral fractures (PPFF), revision arthroplasty should be performed. The first hypothesis of this study was that advanced patient age and female gender shows higher non-union rates. The second hypothesis was that primary cementless arthroplasty is associated with a higher non-union rate compared to cemented primary hip arthroplasty. METHODS All PPFF occurring between January 2000 and June 2010 treated by revision arthroplasty were included. Multiple regression analysis was performed to identify independent variables leading to fracture non-union. RESULTS Eighty one patients (78 % female) met the inclusion criteria. In 20/81 patients (24.7 %) no adequate fracture healing could be determined on radiographs 12 months after revision surgery. Although age and female gender showed a positive correlation with bony non-union after PPFF as expected, the p-values were not statistically significant. Multiple regression analysis revealed primary cementless prosthesis (p = 0.001) to be the only independent variable associated with non-union. CONCLUSION Non-cemented primary prosthesis might be a negative predicting factor for the development of non-union after long-stem revision arthroplasty in PPFF. We therefore recommend the thorough debridement of pannus tissue thus inducing bone healing before the implantation of revision prostheses.

Abstract
BACKGROUND To compare the clinical outcomes of external fixator (EF) and intramedullary nails (IN) in the treatment of open tibial fractures. METHODS We searched seven electronic databases (PubMed, MEDLINE, EMBASE, OVID, Cochrane library, CNKI, and CBM) for trials of tibial fracture fixation published from 1980 to 2013. The indicators including postoperative infection, malunion, nonunion, soft tissue injury, delayed healing, and healing time were used for quantitative outcome assessments. RESULTS A total of nine trials involving 532 patients (EF, n = 253; IN, n = 279) with open tibia fractures were included in this meta-analysis. The results indicated that the patients undergoing IN had lower incidence of postoperative infection (risk radio [RR] = 3.85; 95% confidence intervals [CI], 2.67-5.54; P < 0.0001), malunion (RR = 2.31; 95% CI, 1.40-3.81; P = 0.001), nonunion (RR = 1.41; 95% CI, 1.06-1.88; P = 0.02) and less healing time (weighted mean difference [WMD] = 6.19; 95% CI, 1.42-10.96; P = 0.01) compared with EF. However, regarding to the soft tissue injury (RR = 0.74; 95% CI, 0.34-1.62; P = 0.45) and delayed healing (RR = 1.38; 95% CI, 0.79-2.43; P = 0.26), there is no significantly difference between EF and IN approach. CONCLUSION In conclusion, the use of IN is more effective than EF and may be considered as first-line approach in fixation of open tibial fractures.

Abstract
Objective The purpose of this study is to compare the clinical effects of our self-designed rotary self-locking intramedullary nail (RSIN) and interlocking intramedullary nail (IIN) for long bone fractures. Methods A retrospective study was performed in 1,704 patients who suffered bone fractures and underwent RSIN or IIN operation in our hospital between March 1999 and March 2013, including 494 with femoral fractures, 572 with humeral fractures, and 638 with tibial fractures. Among them, 634 patients were followed up for more than 1 year. The operative time, intraoperative blood loss, postoperative complications, healing rate, and the excellent and good rate of functional recovery were compared between two groups. Results Compared with IIN group, RSIN group exhibited significantly shorter operative time and less intraoperative blood loss no matter for humeral, femoral, or tibial fractures (all p < 0.001). The healing rate in patients with more than 1 year follow-up was significantly higher in RSIN group for femoral and tibial fractures (both p < 0.05). In RSIN group, no nail breakage or loosening occurred, but radial nerve injury and incision infection were respectively observed in one patient with humeral fracture. In IIN group, nail breakage or loosening occurred in 7 patients with femoral fractures and 16 patients with tibial fractures, radial nerve injury was observed in 8 patients with humeral fractures, and incision infection was present in 2 patients with humeral fractures and 1 patient with femoral fracture. The complication rate of IIN group was significantly higher than that of RSIN group (p < 0.05). However, there were no significant differences in the excellent and good rate of shoulder, elbow, knee, and ankle joint functional recovery between RSIN group and IIN group. Conclusion RSIN may be a reliable and practical alternative method for the treatment of long bone fractures.

Abstract
BACKGROUND Intramedullary fixation is the treatment of choice for diaphyseal fractures of the femur and tibia. Locking the implant can sometimes be cumbersome and time consuming. In our institution, fractures with axial and rotational stability are treated with intramedullary nailing without interlocking. METHODS All consecutive patients presented in the University Medical Center Utrecht from October 2003 to August 2009 with acute traumatic diaphyseal fractures of the tibia or femur that were considered axial and rotational stable were included. They underwent internal fixation using intramedullary nails without interlocking. Patient records were evaluated for duration of surgery, perioperative complications, consolidation time and re-operations. RESULTS Twenty-nine long bone fractures were treated in 27 patients: 20 men and 7 women, with an average age of 28.9 years (range 15.6-54.4). There were 12 femoral fractures and 17 tibial fractures. Sixteen fractures were closed and 13 were open (10 Gustilo 1, 3 Gustilo 2). The mean operating time was 43 min (range 18-68 min) for tibial fractures and 55 min (range 47-150 min) for femoral fractures. Postoperative complications occurred in six patients. Two patients (three fractures) were lost to follow-up. Healing occurred in 25 of the 26 remaining fractures (96 %) without additional interventions. One tibia was secondarily converted to a standard locked nail because of axial and rotational instability. All patients returned to their pre-injury level of activity. CONCLUSION The use of intramedullary nailing without interlocking is associated with minimal complications in selected fractures. The advantages include a short operating time and the simplicity of its application.

IRANIAN RED CRESCENT MEDICAL JOURNAL 2013; 15:432-5. [PMID: 24349734 PMCID: PMC3838656 DOI: 10.5812/ircmj.4631] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 02/29/2012] [Revised: 06/13/2012] [Accepted: 01/08/2013] [Indexed: 11/16/2022]
Abstract
Background Stabilization of fractures with an intramedullary nail is a widespread technique in the treatment of femoral shaft fractures in adults; however, to ream or not to ream is still being debated. Objectives The primary objective of this study was to determine clinical results following unreamed versus ream intramedullary nailing of femoral fractures. Patients and Methods Between January 2008 and August 2009, 50 patients with femoral shaft fractures were treated with unreamed or reamed femoral nails in our clinic. From this prospective single centre study, 16 patients were excluded due to insufficient follow-up data. According to the AO classification, fractures in this study were either type A or B. Dynamic proximal locking was performed in all cases. The remaining 34 patients were divided into two groups of 17 with ream or unream nailing. During and after the operation, we evaluated some variables in whole series. Results After statistical analyzes, we found that there were no differences in radiologic union time (P = 1) or full weight bearing time (P = 0.73) between ream and unream nailing. Nail breakage or iatrogenic fractures during nail insertion did not occur and we did not have any fat emboli in both groups but one secondary loss of reduction occurred in the unream group. Superficial infection after the operation was seen in one case which was treated successfully with antibiotics. In the ream group surgical time was about thirty minutes longer and differences were significant (P = 0.000). Patients had to pay more for ream nailing but the difference was not significant. We found no statistical difference between union time with or without reaming; on the other hand, there was significant increased operation length, blood loss and systemic changes in BP or So2 in the ream group versus the unream group. Conclusions We advocate that unream nailing in traumatic femoral shaft fractures is a simple, safe and effective procedure with significant advantages, especially in multitrauma patients.
