Functional and radiological outcomes of suprapatellar intramedullary nailing for tibia diaphyseal fracture-an observational study

Functional and radiological outcomes of suprapatellar intramedullary nailing for tibia diaphyseal fracture-an observational study

Suprapatellar intramedullary nail combined with screw fixation has comparable surgical outcomes to minimally invasive locking plate fixation in ipsilateral tibial plateau and shaft fractures.

To compare union rate, union time, alignment, and complication rate in ipsilateral tibia plateau and shaft fractures treated via suprapatellar intramedullary nailing with screw fixation and minimally invasive locking plate fixation. A retrospective study was conducted on 48 patients who underwent minimally invasive plate fixation (n = 35) or suprapatellar intramedullary nailing with screw fixation (n = 13), for the treatment of ipsilateral tibial plateau and shaft fractures with at least 1-year follow-up. Union rate, union time, radiologic alignment, and complication rate such as malalignment, nonunion, and fracture-related infection (FRI) were investigated. Demographic data were not different between the two groups. Coronal plane alignment was 0.17 ± 4.23 in the plate group and -0.48 ± 4.17 in the intramedullary nail group (p = 0.637). Sagittal plane alignment was -0.13 ± 5.20 in the plate group and -1.50 ± 4.01 in the suprapatellar intramedullary nail group (p = 0.313). Coronal and sagittal malalignment recorded equal results: (p > 0.99), FRI (p = 0.602), nonunion and union times recorded (p = 0.656) and (p = 0.683, 0.829), respectively, and showed no significant difference between the two groups. Suprapatellar intramedullary nailing with screw fixation had similar surgical outcomes with minimally invasive locking plate fixation in ipsilateral tibial plateau and shaft fractures in terms of union rate, union time, alignment, and complication rate. Thus, frequent use of intramedullary nailing combined with screw fixation is anticipated in patients with ipsilateral tibial plateau and shaft fractures when the soft tissue condition is not desirable.

Comparison of suprapatellar intramedullary nailing versus minimal invasive locked plating for proximal tibia fractures.

To compare the radiological alignment, union time, union rate, and complication rate between suprapatellar intramedullary nails and minimally invasive locking plate fixation in the treatment of proximal tibial fractures. We retrospectively analyzed 103 patients who underwent plate fixation (n = 50) or suprapatellar intramedullary nailing (n = 53) for proximal tibial fractures involving the meta-diaphyseal junction between November 2015 and October 2020 at our institution. The union rate, union time, radiologic alignments, and complications, such as malalignment, nonunion, and deep infection, were investigated. The demographic data did not differ between the plate and suprapatellar intramedullary nail groups. The alignment of the coronal plane was 0.24 ± 3.19 in the plate group and - 0.49 ± 2.22 in the intramedullary nail group (p = 0.196). Sagittal plane alignment was - 0.29 ± 4.97 in the plate group and 0.24 ± 4.12 in the intramedullary nail group (p = 0.571), and coronal malalignment (p = 0.196), sagittal malalignment (p = 0.57), deep infection (p = 0.264), nonunion (p = 0.695), union time (p = 0.329), and final union rate (p = 0.699) were not significantly different between groups. Compared with the minimally invasive locking compression plate group, the suprapatellar intramedullary nail group yielded comparable results in terms of radiological alignment and complications. Considering that proximal tibial fractures are associated with high-energy trauma and severe soft tissue damage, we believe that a suprapatellar intramedullary nail may be a good alternative.

Suprapatellar intramedullary nailing of tibial shaft fractures in pregnancy. A report of two cases

BackgroundTreatment of closed tibial shaft fractures in the 3rd trimester of pregnancy is controversial. Since there are few case reports published in literature, there is no consensus on the appropriate management of these fractures. This case report proposes intramedullary nailing throught the suprapatellar approach for the treatment of tibial shaft fracture in pregnant women, never described before in literature.Case presentationWe report 2 cases of a tibial diaphyseal fracture treated by intramedullary nailing in women at the 3rd trimester of pregnancy.ConclusionSurgical treatment of tibial shaft fracture of pregnant women in the 3rd trimester of pregnancy with intramedullary nailing seems to be safe. The use of the specific suprapatellar approach helps in the intra-operative management of the pregnant patients.

Suprapatellar versus infrapatellar approach for intramedullary nail fixation of tibial shaft fractures: a review of the literature.

Semi-extended suprapatellar intramedullary nail fixation of tibial fractures has recently been gaining popularity. Several recent studies and meta-analyses compare the outcomes of the suprapatellar approach with the traditional infrapatellar approach. Despite concerns with intra-articular placement of instruments, studies show the suprapatellar approach to be a safe alternative. Several articles conclude that the suprapatellar approach may be superior to the infrapatellar approach. This review discusses recent findings comparing suprapatellar and infrapatellar approaches for nail insertion.

Removing a suprapatellar intramedullary nail via a suprapatellar approach: a retrospective cohort study.

Over the last 20years, suprapatellar (SP) intramedullary nailing has gained considerable attention for treating tibia fractures and is believed to improve fracture alignments, decrease anterior knee pain, and facilitate intraoperative fluoroscopy. However, it is associated with various concerns, including the need to make another infrapatellar (IP) incision to remove the nail. This study was aimed at developing a new technique for the removal of SP tibial nails through an SP approach using a cannulated extraction system. The efficiency of the novel SP approach was compared to that of the traditional IP approach for the removal of SP tibial nails. This was a retrospective cohort study from a prospectively collected clinical registry. The data for 69 consecutive patients who received surgery to remove a previous SP intramedullary nail using an SP approach (n = 30, SP cohort) or an IP approach (n = 39, IP cohort) were analyzed. Intra-operative evaluations included intraoperative blood loss, operation time, and changes in the surgical procedures. At sixmonths follow-up, post-operative Lysholm knee score, visual analog scale (VAS) score, and the active range of motion (ROM) of the affected knee and complications were assessed. Patients in the SP cohort exhibited an increased post-operative Lysholm knee score (β, 2.6; 95% confidence interval [CI], 0.6 to 4.6; P = 0.012), decreased post-operative VAS score (β, - 0.7; 95% CI, - 1.1 to - 0.2; P = 0.004), and increased operation time (β, 9.8minutes; 95% CI, 5.7 to 14.0minutes; P < 0.001) compared with those treated with the IP approach after adjustment for baseline characteristics. There were no statistically significant differences in blood loss, post-operative ROM, or complications between the two cohorts. Compared with the IP technique, the SP approach for the removal of an SP tibial nail was independently associated with an increased post-operative Lysholm knee score and decreased VAS score, although the surgery was longer in duration. The novel technique offers a reliable and minimally invasive option for the removal of an SP tibial nail.

Functional Outcomes in Suprapatellar Nailing for the Treatment of Tibial Shaft Fractures

Introduction: The purpose of this study was to evaluate the functional outcomes of suprapatellar intramedullary nailing for the treatment of tibial shaft fractures.Material and Methods: The present retrospective study included 10 cases aged more than 20 years, who were operated for tibial shaft fractures over last 3 years with suprapatellar tibial nailing. Patients were retrospectively followed up with all their previous surgical records and radiographs.Results: The mean age was 41.57±16.51 with a range of 20-72 years. Mean operating time was 81±10.15 minutes. Mean blood loss was 110±20.5 ml. Mean time for union was 15.15±1.35 weeks. No deep infection was noted. 1 patient had anterior knee pain. The mean Lysholm knee score was 87.91 ± 5.75.Conclusion: The suprapatellar approach is good and safe technique for nailing in the tibial fractures.

Suprapatellar intramedullary nailing of the tibia

Objective: To report our experience with intramedullary fixation and osteosynthesis of the tibia with suprapatellar approach and semiextended positioning. Methods: This study retrospectively assessed 6 patients with tibial fracture treated with suprapatellar intramedullary nail fixation and osteosynthesis from September 2015 to September 2018. Results: There was acceptable bone fixation. Mean healing time was 6 months (range: 4-10 months). Postoperative pain was assessed using a visual analog scale, and the knee was divided into 9 quadrants to help locate the specific site of pain; all participants reported that pain was located at distal quadrants. Knee function was completely restored. Conclusion: Suprapatellar approach with the knee in the semiextended position is a good surgical technique for extra-articular proximal tibial fractures or those associated with soft tissue involvement at the conventional infrapatellar entry site. Thus, this analysis led us to believe that the technique should also be applicable to middle diaphyseal fractures or fractures in general, regardless of their location.

A comparison of the use of a suprapatellar Chinese Aircraft-shaped Sleeve System versus suprapatellar intramedullary nailing for tibial shaft fractures: Outcomes over a one-year follow-up

IntroductionThis study aimed to investigate the effectiveness and safety of the Chinese Aircraft-shaped Sleeve (CASS) system on the clinical outcomes of tibial intermedullary nailing using a suprapatellar approach for the treatment of tibial fractures in a cohort of adult Chinese patients over a minimum one-year follow-up. MethodsAfter institutional review board approval, skeletally mature patients with Orthopaedic Trauma Association (OTA) type 42 tibial shaft fractures were randomized into either a SP approach using CASS group or a conventional SP approach group after informed consent was obtained. The operations were performed by a single senior orthopaedic surgeon according to group assignments. A group of 33 patients were treated using the CASS system and the other group of 34 patients were treated using a conventional SP approach. Both groups fully complied with research requirements and completed 12 months of follow-up. Magnetic resonance images (MRI) were obtained for the evaluation of the patellofemoral joint (PFJ) and residual debris preoperatively, as well as one week and 12 months postoperatively. Radiographs were used to assess alignment and union, visual analog scores (VAS) were used to assess anterior knee pain, and range of motion (ROM) and the Lysholm knee scoring scales were used for evaluating the operated knee at the 12-month follow-up. ResultsDifferences in cartilage lesion changes observed by MRI between the two groups were statistically significant (P = 0.030 at 1 week postoperatively; P = 0.025 at 12 months postoperatively). No significant differences were evident with respect to debris residue, malalignments, nonunion, VAS, ROM and Lysholm knee scoring scale with the exception of stair climbing (P = 0.02). ConclusionBased on the data of this one-year clinical follow-up study, the SP approach using the CASS system offers the potential to benefit patients suffering from tibial shaft fractures, who will be treated with intramedullary nailing especially for smaller patients.

Treatment of Combined Tibial Plateau and Shaft Fractures

Separate ipsilateral tibial plateau and shaft fractures are rare and complicated injuries. They are associated with high energy mechanisms and may present with significant soft tissue as well as life threatening nonorthopaedic trauma. Meticulous preoperative planning is essential when determining the appropriate fixation construct. Utilization of a single locking plate in a minimally-invasive fashion is a common fixation option. Unfortunately, this fixation method is technically demanding and may not provide the optimal biomechanical environment needed for healing of the plateau and/or shaft fracture leading to nonunion and possible hardware failure. This paper describes fixation techniques for ipsilateral tibial plateau and shaft fractures that combine suprapatellar intramedullary nailing of the shaft with separate plate fixation of the tibial plateau. While also technically demanding, with close attention to preoperative planning, these techniques allow for fracture specific fixation of both the tibial plateau and shaft. In doing so, the ideal implant for each fracture is utilized which optimizes the environment for subsequent fracture healing and return to function.

Comparison of suprapatellar and infrapatellar intramedullary nailing for tibial shaft fractures: a systematic review and meta-analysis

BackgroundOptimal surgical approach for tibial shaft fractures remains controversial. We perform a meta-analysis from randomized controlled trials (RCTs) to compare the clinical efficacy and prognosis between infrapatellar and suprapatellar intramedullary nail in the treatment of tibial shaft fractures.MethodsPubMed, OVID, Embase, ScienceDirect, and Web of Science were searched up to December 2017 for comparative RCTs involving infrapatellar and suprapatellar intramedullary nail in the treatment of tibial shaft fractures. Primary outcomes were blood loss, visual analog scale (VAS) score, range of motion, Lysholm knee scores, and fluoroscopy times. Secondary outcomes were length of hospital stay and postoperative complications. We assessed statistical heterogeneity for each outcome with the use of a standard χ2 test and the I2 statistic. The meta-analysis was undertaken using Stata 14.0.ResultsFour RCTs involving 293 participants were included in our study. The present meta-analysis indicated that there were significant differences between infrapatellar and suprapatellar intramedullary nail regarding the total blood loss, VAS scores, Lysholm knee scores, and fluoroscopy times.ConclusionSuprapatellar intramedullary nailing could significantly reduce total blood loss, postoperative knee pain, and fluoroscopy times compared to infrapatellar approach. Additionally, it was associated with an improved Lysholm knee scores. High-quality RCTs were still required for further investigation.

No Incidence of Postoperative Knee Sepsis With Suprapatellar Nailing of Open Tibia Fractures.

To evaluate the incidence of knee sepsis after suprapatellar (SP) nailing of open tibia fractures. Retrospective; Setting: ACS level 1 trauma center. We reviewed 139 open tibia fractures that underwent SP nailing as definitive treatment over a 5-year period (January 1, 2011 to January 1, 2016). Most patients (90%, n = 126) underwent intramedullary nailing at the time of their initial surgery. We defined knee sepsis as intra-articular infection requiring operative debridement, either open or arthroscopically, within 1 month's time. Open tibia fractures treated with an SP tibial nail. Demographic data, fracture characteristics, Gustilo and Anderson classification of open fractures, and occurrence of knee sepsis. In 139 open tibia fractures, there were no cases of knee sepsis in the 30 days after treatment with an SP intramedullary nail. Eighty-seven percent of our cohort had Gustilo and Anderson type II (41%) or type III (46%) open fractures. Most open fractures (83%) underwent primary wound closure during the index procedures. Twenty-five limbs (18%) had evidence of infection at the open fracture site of their open fracture necessitating operative intervention and/or antibiotics: none, however, developed knee sepsis. Although the SP approach carries intra-articular risks, we found a low risk of knee sepsis using this technique in the treatment of open tibia fractures. Our data suggest that there is no greater risk of intra-articular infection using an SP portal as compared with an infrapatellar one. Therapeutic Level IV.

Suprapatellar Intramedullary Nail Technique Lowers Rate of Malalignment of Distal Tibia Fractures.

To report on the immediate postoperative alignment of distal tibia fractures (within 5 cm of the tibial plafond) treated with suprapatellar intramedullary nail (IMN) insertion compared with the infrapatellar technique. Primary outcomes include alignment on both the anteroposterior and lateral radiographic views. Retrospective cohort study. Two urban level I trauma centers. A total of 266 skeletally mature patients with a distal tibia fracture were treated with an IMN. One hundred thirty-two patients underwent this procedure through a suprapatellar technique. Intramedullary nail placement. Alignment. The 2 treatment groups were evenly matched with respect to age, gender, fracture grade, and the presence of open fracture. Within the suprapatellar group, the fibula was intact, fixed, and remained fractured in 6 (4.5%), 22 (16.7%), and 104 (78.8%) cases, respectively. The fibula was intact, repaired, and remained fractured in 9 (6.7%), 32 (23.9%), and 93 (69.4%) cases, respectively, in the infrapatellar group. There was no difference in the rate of fibular fixation between the groups (P = 0.2). Primary angular malalignment of ≥5 degrees occurred in 35 (26.1%) patients with infrapatellar IMN insertion and in 5 (3.8%) patients who underwent suprapatellar IMN insertion (P < 0.0001). This is the largest patient series directly comparing the suprapatellar with infrapatellar IMN insertion technique in the treatment of distal tibia fractures. In the treatment of distal tibia fractures, suprapatellar IMN technique results in a significantly lower rate of malalignment compared with the infrapatellar IMN technique. Therapeutic Level III.
