Semiextended position of intramedullary nailing of the proximal tibia

Plate vs. Nail: Is there a more effective implant for extreme tibia fractures?

Background

The purpose of this study is to determine differences in outcomes between "extreme" tibial metaphyseal fractures treated with intramedullary nailing (IMN) or plate osteosynthesis.

Methods

545 prospectively collected patients were reviewed by two board-certified orthopedic trauma surgeons to identify extreme tibial shaft fractures (defined as most proximal or distal segments that involved or would have involved the area encompassed by the nail locking bolts). Fifty-one patients were identified. Twenty-five patients treated with an intramedullary nail were compared to 24 patients treated with plate and screws for similar patterns. Data collected included patient demographics, surgical details, and outcomes. Cohorts were compared using fisher's exact test, independent T tests, and multivariable linear regression.

Results

The mean age of all patients was 46.73 years. There were no differences in ASA, CCI, age, male/female composition, or BMI between cohorts. There were no differences in low vs. high-energy mechanism of injury between cohorts, however the IMN cohort had a greater proportion of open fractures (p = 0.018). When controlling for covariates, patients who underwent IMN were allowed earlier weight bearing on the operative extremity. There were no differences in ankle or knee range of motion at latest follow up. There was a greater incidence of total complications among IMN (p = 0.033). Single variable analysis revealed an association between IMN and nonunion (p = 0.050). IMN trended towards greater need for reoperation (p = 0.086).

Conclusion

Intramedullary nailing of "extreme tibia fractures" was associated with higher rates of total complications compared to plate osteosynthesis and trended with greater need for reoperation. However, it should be noted that there was a higher incidence of open fractures in this cohort. There were no differences in the rate of malalignment, range of motion, or time to healing between cohorts.

Refined Techniques in Tibial Nailing

Intramedullary nail fixation of unstable tibial diaphyseal fractures is commonly used with excellent clinical results. Indications for nailing have rapidly expanded over recent years, allowing for more difficult fractures to be addressed with "extreme nailing." Despite its widespread use, evolution of newer nailing systems and varying techniques for insertion bring new difficulties with tibial fracture reduction, and malalignment occurs with relative frequency. This highlights the need for a methodical approach for efficient and predictable tibial nailing. An algorithmic approach is essential, beginning with identifying challenging patterns in proximal and distal fractures and addressing any intra-articular elements initially. A semiextended approach is helpful to neutralize deforming forces. Optimizing the starting point and confirming lateral termination of the guidewire mitigate fracture malreduction after nail placement. Fracture reduction is facilitated with clamps, fibular or tibial plating, blocking screws or wires, external fixation, universal distractor, or manual manipulation to optimize outcomes and avoid pitfalls in an effective tibial nailing.

Anterior Knee Pain and Knee Functional Scores Following Common Approaches to Tibial Shaft Fractures: A Systematic Review

Background

Tibial shaft fractures are common, causing substantial morbidity. Intramedullary nailing offers advantages but often leads to anterior knee pain and functional issues.

Methods

Following Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, we conducted a systematic review on outcomes for different surgical approaches-suprapatellar (SP), infrapatellar (IP), medial parapatellar (MPP), and lateral parapatellar (LPP). Searches across Ovid, Embase, and PubMed identified studies from 2000 to 2023, including retrospective and prospective studies, randomized controlled trials, and case series on anterior knee pain and functional outcomes postsurgery. Bias was assessed using Cochrane's RoB2.

Results

Of 27 studies, 8 were noncomparative (3 SP, 3 IP, 1 MPP, 1 LPP), showing varied anterior knee pain and function outcomes. Comparative studies (12 SP vs. IP, 5 MPP vs. IP) indicated better patient-reported outcomes for SP over IP in anterior knee pain and knee function. Comparative data for MPP and LPP remain limited. Overall RoB was low.

Conclusion

SP has better patient-reported outcomes and lower anterior knee pain than IP. MPP and LPP approaches are promising but lack robust comparative data. Further large, prospective trials are needed to clarify optimal approaches for tibial shaft fractures.

Comparison of the efficacy of intramedullary nailing via the lateral parapatellar approach versus the infrapatellar approach in the treatment of tibial metaphyseal-diaphyseal junction fractures

BACKGROUND

To compare the efficacy of intramedullary nailing via the lateral parapatellar approach versus the infrapatellar approach in treating fractures at the tibial metaphyseal-diaphyseal junction.

METHODS

A retrospective analysis was conducted on the clinical data of 45 patients with proximal or distal tibial fractures treated with intramedullary nailing via lateral parapatellar approach (n = 23) or infrapatellar approach (n = 22) between January 2019 and March 2023. We recorded and compared the operative time, intraoperative blood loss/fluoroscopies, success rate of closed reduction, anteroposterior and lateral entry point accuracy, postoperative infection, fracture healing time, as well as NRS pain scores, Lysholm knee function scores, and knee range of motion.

RESULTS

Both groups completed the surgery without any complications. The lateral parapatellar approach group had significantly better results regarding shorter operative time, less intraoperative blood loss, and fewer intraoperative fluoroscopies compared to the infrapatellar approach group (P < 0.05). All cases in the lateral parapatellar approach group achieved closed reduction, while 10 cases in the infrapatellar approach group required open reduction. Fractures in both groups healed successfully, without statistically difference in healing time (P > 0.05). The accuracy of anteroposterior and lateral entry points was better with lateral parapatellar approach (P < 0.05). At 3 and 12 months postoperatively, lateral parapatellar approach showed better Lysholm and NRS scores compared to infrapatellar approach (P < 0.05). Two groups had no significant difference in range of motion (P > 0.05).

CONCLUSIONS

Lateral parapatellar approach combined with the blocking screw technique provides superior clinical outcomes compared to infrapatellar approach in the treatment of proximal or distal tibial fractures, making it suitable for further investigation.

Comparison of Efficacy of Suprapatellar and Infrapatellar Approaches for Intramedullary Interlocking Nailing of Tibia in Patients With Tibial Fracture

INTRODUCTION

Intramedullary interlocking nailing is a common surgical procedure for tibial fractures, enabling early patient mobilization. Traditionally, the infrapatellar approach has been used for intramedullary interlocking nailing of tibial fractures, but the suprapatellar approach is gaining attention for its potential benefits. This randomized controlled study aimed to compare the duration of the surgery, intra-operative blood loss, and fluoroscopy time between the suprapatellar and infrapatellar approaches.

METHODS

We included 38 adult patients with tibial shaft fractures, excluding those with non-union, open fractures, revision surgery, or low Glasgow Coma Scale (GCS). Patients were divided equally into two groups using block randomization: Group A (19 patients) underwent the infrapatellar approach, and Group B (19 patients) underwent the suprapatellar approach. Blood loss was measured using the gravimetric method and by changes in pre-operative and post-operative hemoglobin levels. Surgical duration by calculating the time elapsed between the start and end of the procedure and fluoroscopy time was logged from the fluoroscopy machine.

RESULTS

In group A, blood loss averaged 154±30.98 mL, slightly more than in group B (150±32.92 mL), though the difference was not statistically significant (p>0.05). Group A also showed a higher difference in hemoglobin levels (2.20±1.13 g/dL) compared to group B (1.15±0.93 g/dL), which was statistically significant (p=0.02). Fluoroscopy time and duration of the surgery were slightly longer in group A compared to group B but not statistically significant (p=0.693).

CONCLUSION

The suprapatellar approach results in less blood loss, potentially promoting faster recovery, reduced need for blood transfusions, and shorter hospital stays. It also entails shorter fluoroscopy time and surgical duration, though not statistically significant, which may reduce radiation exposure for the surgical team.

A Prospective Study on Tibial Shaft Fractures Treated with Suprapatellar Approach

Background

Tibial diaphysis represents the primary location for tibial fractures, accounting for 80% of such cases, often accompanied by fibular fractures. In terms of surgical management, the recommended technique for addressing both displaced and undisplaced tibial shaft fractures in adults is intramedullary nail fixation. Additionally, there is a growing consideration for suprapatellar nailing, which involves performing the procedure with the knee in a semi-extended position, as a potentially safe and efficacious alternative.

Objectives

To evaluate the clinical and functional union amongst tibial shaft fracture cases, managed by nailing in the suprapatellar approach, and to study the complications associated with it.

Materials and Methods

Our study with prospective observational design was conducted for 18 months on 30 patients with tibial shaft fractures. Following comprehensive laboratory assessments and confirmation of surgical fitness, the patients underwent surgical intervention through a specialised suprapatellar approach employing expert tibial nailing.

Results

The mean age of the subjects was 42.83 ± 11.47 years, and the majority were males (70.0%). Notably, there was a statistically significant reduction in Visual Analogue Scale scores and a concurrent increase in Lysholm Knee Scoring Scale scores during the follow-up period, indicating substantial enhancements in both clinical and functional outcomes. Delayed union was the complication observed in three individuals. We found that the younger the age of the subjects, the earlier the surgery after an injury, the better the functional outcome.

Conclusion

Expert tibial nailing with a suprapatellar approach was successful in yielding clinical and functional union amongst the subjects with tibial shaft fractures. In addition, delayed union was the complication observed in the approach, which was evident in a few cases.

Assessment of functional and radiological outcomes of suprapatellar and infrapatellar approaches of tibial nailing in patients with tibial shaft fracture: A randomized control study

Background

The study aimed to assess functional and radiological outcomes of the suprapatellar approach (SPA) and infrapatellar approaches (IPA) of tibial nailing in patients with closed tibia shaft fractures.

Method

After Institutional Ethical Committee (IEC) and Clinical Trials Registry- India (CTRI) approval, patients with Orthopaedic Trauma Association (OTA) fracture type 42 were enrolled from August 2021 and August 2022 at a level I trauma centre and randomized to SPA and IPA with informed consent. Demographics, American Society of Anaesthesiologists (ASA) physical grading, intraoperative fluoroscopy time, operative duration, bleeding, postoperative radiographic alignment, and union were compared among both approaches. Functional parameters like Lysholm knee score, Anterior knee pain (AKP), Visual Analog Scale (VAS) Score upon kneeling, Knee Injury and Osteoarthritis outcome score (KOOS), KOOS Patellofemoral score (KOOS PF), EuroQol (EQ5D5L), Forgotten joint score (FJS), Range of motion (ROM) of knee and any complications were assessed at 3,6 and 12 months postoperatively.

Results

Per protocol analysis of 50 patients (25 SPA, 25 IPA) done at the end of the study. SPA group had significantly lesser fluoroscopy time (91.28 ± 12.40s vs. 105.36 ± 9.23s, p < 0.001) and operative duration (mins) (123.80 ± 24.25 vs. 130.00 ± 18.20, p < 0.001) than IPA. No significant differences were noted in Lysholm knee score at three months (p = 0.094), six months (p = 0.406), and 12 months (p = 0.071). The SPA group showed significantly lower VAS Score upon kneeling at six months (p < 0.0001). Similarly, KOOS (p < 0.001), KOOS PF (p = 0.01), and EQ 5D5L (p = 0.03) were significantly better in the SPA group at six months postoperatively. Lower Coronal translation was found in SPA [0 (0-1.8) vs. 1.4 (0.9-1.8), p = 0.010]. Whereas, IPA had higher range of flexion at 3 months [130.0 (129.0-135.0) vs 123.1 (120.0-130.5), p = 0.047]. However, no significant differences were noted in blood loss, AKP, FJS, EQ-VAS, coronal angulation, sagittal malalignment, time to union, return to work and postoperative complications among the groups.

Conclusion

SPA has lesser surgery time, more straightforward anatomic fracture reduction, better fracture alignment, lesser radiation exposure for both patients and surgeons, quicker recovery time, and promotes early kneeling activities with similar long-term functional outcomes and union rates, and can be considered in routine clinical practice than conventional IPA.

Outcomes and their predictors in suprapatellar nailing for tibia fractures. Multivariable analysis of 293 consecutive cases

PURPOSE

Intramedullary nailing of tibial fractures is one of the most common procedures in orthopedic surgery. It can be technically demanding in proximal or distal fractures, which may be facilitated using semi-extended approaches. The aim of this study is to identify outcomes and their predictors using a semi-extended suprapatellar approach for tibial fracture nailing.

METHODS

This is a retrospective cohort of 293 patients who underwent intramedullary nail fixation of a tibial fracture through a suprapatellar approach, considering a postoperative follow-up of 1 year. Data on patient's baseline characteristics, injuries, treatments, and outcomes regarding alignment, fracture union, and complications were recorded. For multivariable analysis, hierarchical binary (logistic) regression analysis was performed.

RESULTS

The mean patient age was 47.7 years (SD 18.9), with 42A1 the most frequent fracture pattern (n = 98, 33.5%). Correct or anatomical alignment (≤ 5º in both planes) was achieved in 272 (92.8%) of the patients. On multivariate analysis, surgical delay ≥ 7 days (OR = 1.3, 95% CI = 1.3-8.1) and age over 50 years (OR = 3.2, 95% CI = 1.2-8.3) were found as predictors of fracture malalignment. Fracture healing was achieved in 97.6%, and reoperation rate was 6.14%. Overall complication's predictors were proximal fracture (OR = 2.8, 95% CI = 1.1-7.2), temporary external fixation (OR = 2.4, 95% CI = 1.2-4.9), and fracture malalignment (OR = 2.9, 95% CI = 1.1-7.9).

CONCLUSION

The suprapatellar approach is a safe and useful technique for treating tibial fractures, leading to no less than correct reduction in almost all patients and achieving a high fracture healing rate, at very low rates of complications. Pre- and postoperative predictors identified must be taken into account to improve outcomes while treating these fractures.

Osteosynthesis by locking plate for proximal tibial fractures

INTRODUCTION

Treatment of proximal tibial fractures is known to be difficult. We report our own experience of the treatment of these fractures and evaluate our results. The hypothesis was that the clinical and radiological results were good.

MATERIAL AND METHOD

From January 2004 to October 2008, fourteen AO-type 41A2-3 and C1 fractures have been treated with a LCP locking plate (8 women and 6 men, average age 60.42). Plating was performed either with an open approach or a minimal invasive approach. Clinical and radiological follow-up was carried out looking for range of motion of the knee joint and autonomy level.

RESULTS

Mean follow-up was 32.63 months (12-70). Range of motion was maintained with a mean arch of 117.5° Autonomy was maintained in all cases. Professional, domestic and sports activities were unchanged. No infection or general complication occurred. Bone fusion was obtained in all cases after an average of 13.28 weeks. 6° of valgus deformation, already seen immediately postoperatively was observed once. Secondary displacement was observed in 6 cases, with an average of 2.83° DISCUSSION-CONCLUSION: We report good radiological results, with only one initial malalignment. The hypothesis was confirmed. However, X-ray analysis at consolidation shows 6 secondary displacements, without any satisfactory explanation. Though the clinical consequences of these malunions are minimal. Osteosynthesis with plate, in the sight of this study, yields good clinical results. Radiological evolution concerning the evolution of bone axes puts the emphasis on careful operative technique and adequate time to weight bearing.

Fixation of Proximal Tibial Fractures with Intramedullary Nail and Immediate Weightbearing: A Beneficial Alternative

Newer intramedullary (IM) nails have become another option in the fixation of proximal tibia fractures. There is limited data on the successful use of these implants in intra-articular and extra-articular fractures of the proximal tibia, and no studies assessing the ability of these implants to maintain alignment with early weight bearing. Our objective was to determine whether immediate weight bearing after IM fixation, with or without supplemental plate or screw fixation, of proximal third tibial fractures (OTA/AO 41A-C) results in a change in alignment prior to union. 35 patients with 39 proximal tibia fractures from 2015 to 2020, all treated with IM nailing with or without supplemental plate or screw fixation, all made weight-bearing as tolerated following surgery, were included. The main outcomes were change in medial proximal tibial angle (MPTA) and posterior proximal tibial angle (PPTA) from initial post-operative films to final follow up. 12 fractures were OTA/AO 41 type A, 14 were type B, and 13 were type C. Mean initial MPTA was 87.0 +/-2.53 degrees, while mean initial PPTA was 79.6 +/- 3.50 degrees. The mean change in MPTA was 0.048 +/- 2.8 degrees (P=0.92), and mean change in PPTA was 0.264 +/- 3.67 degrees. 92.3% of fractures had normal final coronal plane alignment, with MPTA between 85.0 and 90.0 degrees. 89.7% of fractures had normal final sagittal plane alignment, with PPTA between 77.0 and 84.0 degrees. No patients required reoperation for malalignment. In OTA/AO type 41 fractures, immediate weight bearing after IM nail fixation, with or without supplemental plate or screw fixation when indicated, leads to minimal change in final coronal or sagittal alignment, and was well tolerated in most patients.

The Lateral Para-Patellar Approach for Intramedullary Tibia Nailing in Distal Tibia Extra-articular Fractures: A Prospective Cohort Study

BACKGROUND AND OBJECTIVES

 The treatment of extra-articular distal tibia fractures is still a subject of debate and frequently necessitates surgical treatment, and intramedullary nailing (IMN) offers a minimally invasive approach with excellent results. Important factors in these procedures are positioning, operative duration, and radiation exposure. This study details the semi-extended lateral para-patellar approach for IMN of distal tibia extra-articular fractures and documents our findings regarding operative time, intra-operative radiation exposure, residual anterior knee pain, knee functional and radiological outcomes at six months follow-up.

METHODS

We reviewed the cases of 60 patients who underwent IMN for distal tibia extra-articular fractures from May 2022 to March 2024, employing an extra-articular lateral para-patellar approach in the semi-extended position. Patients were evaluated clinically and radio-graphically for a minimum follow-up period of six months. Data collected included duration of surgery, intraoperative radiation exposure, and knee functional score for all patients. Assessment of fracture healing, residual deformities, residual anterior knee pain, and range of motion of the treated knee compared to the contralateral knee was done at a six-month follow-up.

RESULTS

The average surgery duration was 54 ± 5 minutes, with intraoperative imaging averaging 48 exposures. The average time to union was 16 ± 3 weeks. Six months post-surgery, the mean Knee Society Score was 86.4 ± 3.5 (out of 100). At the six months follow-up, all patients exhibited clinical and radiographic healing, with only two cases showing mal-alignment (angular deformity <10 degrees). All patients regained a comparable range of motion in their knees.

CONCLUSIONS

The semi-extended lateral para-patellar approach for nailing of distal tibia extra-articular fractures enhances reduction, simplifies nail insertion, reduces both fluoroscopy and operative time, minimizes anterior knee pain and improves knee functional outcomes at six months follow-up.

A Suprapatellar Approach, When Compared With an Infrapatellar Approach, Yields Less Anterior Knee Pain and Better Patellofemoral Joint Function, for Intramedullary Nailing of Diaphyseal Tibial Fractures: Results of a Randomized Controlled Trial

OBJECTIVES

To assess if a suprapatellar (SP) approach, when compared with an infrapatellar (IP) approach, yielded less patient-reported anterior knee pain and higher patellofemoral joint function at 6 weeks and 12 months postoperatively, when treating tibial fractures with intramedullary nailing.

METHODS

DESIGN

Prospective, parallel-group randomized control trial.

SETTING

Tertiary level 1 trauma care center, Brisbane, Australia.

PATIENTS SELECTION CRITERIA

Skeletally mature patients with an acute diaphyseal tibial fracture (AO/OTA 41A2/3, 42 A1-43A3) amenable to an intramedullary nailing were included. Exclusion criteria were periprosthetic fractures, nonunions, and presence of a contralateral injury that would restrict weight-bearing.

OUTCOME MEASURES AND COMPARISONS

Anterior knee pain through the visual analog scale (VAS) and patellofemoral function using the Kujala scale at 6 weeks and 12 months were compared between those treated with a SP and IP approach.

RESULTS

Ninety-five tibia fractures were included in the randomized trial, with complete follow-up data for 44 and 46 tibia fractures in the SP and IP groups, respectively. The SP cohort exhibited better patellofemoral knee function at both 6 weeks (Kajula 53.0 for SP vs. 43.2 for IP, P < 0.01) and 12 months (Kujala 92.0 for SP vs. 81.3 for IP, P < 0.01) postoperatively and a reduction in anterior knee pain at 12 months postoperatively (VAS 0.7 SP vs. 2.9 IP, P < 0.01).

CONCLUSIONS

This randomized trial demonstrated clinically meaningful differences in patellofemoral function, for a SP versus IP approach, with a greater than 10 point discrepancy in Kujala score at both 6 weeks and 12 months. In addition, there was a clinically important difference in VAS knee pain scores for patients at 12 months, but not at 6 weeks, postoperatively. These results contribute to the growing body of evidence demonstrating the functional and clinical benefits of the SP approach.

A systematic review and meta-analysis comparing suprapatellar versus infrapatellar approach intramedullary nailing for tibal shaft fractures

BACKGROUND

The application of the suprapatellar (SP) approach has challenged the traditional infrapatellar (IP) approach in the surgery treatment of tibial shaft fractures, yet the advantages and disadvantages still remain controversial. We included more high-quality studies for this meta-analysis and systematic review to evaluate the clinical outcomes and prognosis of both approaches and thus to provide new ideas for surgeons.

METHOD

We searched literatures from PubMed, Cochrane Library, Web of Science, and EMBASE databases from January 2000 to December 2022. We extracted general information including sample size, gender, proportion of open fracture, follow-up time, and outcome indicators including entrance accuracy, fluoroscopy time, operation time, intraoperative blood loss, Lysholm score, VAS pain score, range of motion (ROM) function score, reposition accuracy, and revision cases. Cochrane Collaboration's tool and the Newcastle-Ottawa Scale were used to evaluate literature qualities. Meta-analysis was performed using RevMan 5.4 software.

RESULTS

A total of 23 studies were generated that qualified for inclusion, 17 of which were used for meta-analysis. This study found statistically significant differences in coronal plane entrance accuracy, fluoroscopy time, Lysholm score, and VAS pain score.

CONCLUSION

The results of our meta-analysis showed that the SP approach was significantly better than the IP approach in angle and distance entrance accuracy of coronal plane, angle entrance accuracy of sagittal plane, fluoroscopy time, Lysholm score, and VAS pain score. There were no significant differences in sagittal angle accuracy, operative time, intraoperative blood loss, and ROM score.

The absence of reporting standards and a lack of objective, performance-based outcomes following intramedullary nailing of tibial shaft fractures: findings from a scoping review into 179 articles

PURPOSE

This scoping review was conducted to summarise the outcome tools reported in the assessment of tibial shaft fractures treated with intramedullary (IM) nailing, with a key focus on knee pain and function, and performance-based outcomes.

METHODS

PubMed and Embase databases were searched on May 31, 2023. All study designs and populations were included, including ex vivo studies without fracture. Studies with only open or intra-articular fractures, or other fracture fixation, were excluded. Reported outcome tools and pertinent study characteristics were extracted and summarised.

RESULTS

Of 488 articles identified, 179 met the inclusion criteria. For in vivo studies (n = 152), there were 13,705 fractures; the IM nailing approach not described for 30% of these. There were 133 unique patient outcomes, with a binary assessment of knee pain (29% of studies) and Lysholm score (21%) most common. Only 10/152 (7%) in vivo studies included an objective, performance-based measure of knee function. Fracture union was most frequent (52%) of 81 different clinical outcomes. For ex vivo studies (n = 29), there were 408 tibias included, with nail insertion location most prevalent (66% of studies) of 34 reported outcomes.

CONCLUSION

The heterogeneity of outcome tools reported limits comparison between studies and the most commonly reported patient outcomes may not be the most appropriate. Future studies should report the IM nailing approach and consider capturing both patient-reported and performance-based outcomes to help inform surgical decision making.

Suprapatellar nailing in complex Tibial Fractures

PURPOSE

This study evaluates the functional and radiological outcomes of segmental and comminuted tibial fractures using a suprapatellar approach in semi extended position.

METHODS

A total of 62 patients, with a mean age of 40.8 (range: 21-78 yrs) and 43 males and 19 females, were retrospectively evaluated between January 2017 and December 2022. Patients with comminated tibial fracture AO Type 42 C3 (32) and segmental AO Type 42 C2 (21) AO Type 42 C1 (9) were treated with a IMN using the suprapatellar technique. There were 51 closed fractures and 11 grade-one open fractures. All patients were subjected to the suprapatellar nailing technique in the semi-extended position.

RESULTS

Fracture healing 20.4 weeks on average was needed for the fracture to heal in segmental and 21.2 weeks in comminuted fracture. There were two instances of the delayed union in comminuted fractures. In two cases of segmental fracture dynamization is required. One case of non-union required bone grafting in a segmental fracture and in two instances in comminuted fractures to improve union after four months of monitoring. Primary union occurred in 56 patients. After minimum of 10.2 months of follow-up. According to Johner and Wruh's criteria with modifications, out of 62 patients, 47 had excellent results, 10 had good results, and 5 had fair results.

CONCLUSIONS

In segmental and comminuted fracture tibia, the suprapatellar IMN technique in a semi-extended position results in a significantly lower rate of malalignment, and good union because of soft tissue friendly bypass surgery.

Intramedullary nail versus minimally invasive plate osteosynthesis for displaced extraarticular proximal tibia fractures: a prospective comparative cohort study

PURPOSE

The treatment of extraarticular proximal tibial fractures is challenging. As the optimal fixation technique is still debated, the purpose of this study was to compare minimally invasive plate osteosynthesis (MIPO) and intramedullary nail (IMN) fixation.

METHODS

A prospective matched comparative study was conducted on patients with displaced extraarticular proximal tibia fractures treated with MIPO (n = 29) versus IMN (n = 30) fixation. Outcomes collected were the Johner-Wruhs grading, range of motion (ROM), union rate, time to union, malunion, coronal and sagittal alignment, and post-operative complications.

RESULTS

Union rates were similar between the MIPO and IMN groups (93% vs. 97%, P = 1.0). The IMN group had an earlier time to union (15 vs. 18 weeks, P < 0.001) and superior functional outcomes at one year (effective Johner-Wruhs score: 80% vs. 55%, P = 0.04). There was a significantly higher incidence of anterior knee pain in the IMN group (23% vs. 0%, P = 0.02) and there was a trend for more infections in the MIPO group (21% vs. 13%, P = 0.73).

CONCLUSION

IMN fixation of extraarticular proximal tibia fractures was associated with a shorter union time and better functional scores compared to MIPO.

Semi-extended extra-synovial (SEES) tibial intramedullary nailing technique: Up to 10 year retrospective analysis of outcomes and anterior knee pain rates

Background

Tibial intramedullary nailing is a common method of fixation for fractures of the tibia, with several approaches described. Anterior knee pain is a common complication following nailing, but the reported incidence of knee pain varies in the literature between 10 % and 86 %. There is considerable variation in incidence between nailing techniques, with an exact aetiology still unknown. We investigated the reported incidence of anterior knee pain in patients undergoing tibial nailing using the semi-extended extra synovial (SEES) technique at a Major Trauma Centre (MTC) in the UK.

Methods

A retrospective review of tibial fractures treated with the SEES technique between December 2012 to February 2021. Data collected included patient demographics, mechanism of injury, fracture characteristics, length of stay, union rates and re-operation rates. Primary outcomes were anterior knee pain rates and patient reported outcome measures (PROM), the Kujala Score. Secondary outcomes were rates of union and complications.

Results

55 fractures were identified in 53 patients. Male: Female ratio was 32:21. The average age was 45.5 years. 96 % were unilateral fractures; with 53 % being right-sided. 21(38 %) fractures were open. Prior to definitive nailing 21 fractures had temporary stabilisation with an external fixator (Ex-Fix) ± wound debridement whilst the rest received plaster backslab immobilisation. 13 of the open fractures required soft tissue cover. 75 % of patients had initial surgery (SEES Nailing/Ex-Fix) within 4 days. There was a 91 % union rate with a median time to full radiographic union of 14 months. One post-operative complication of wound dehiscence was recorded. The mean follow-up time was 13.6 months. 15 % of patients reported anterior knee pain in the postoperative follow-up period. The average Kujala PROM score was 85 (Range: 52-100).

Conclusion/findings

The SEES technique had favourable PROM scores and displayed a lower incidence of anterior knee pain than the traditional infrapatellar approach. Knee pain rates were comparable to suprapatellar approaches without violating the knee joint.

Is Patellar Instability a Contraindication to Semiextended Tibial Nailing?: A Case Report

CASE

We report a 40-year-old woman with undiagnosed patellofemoral instability that worsened 8 months after intramedullary nailing of a distal left tibia fracture in the semiextended position through a partial medial parapatellar approach. Patella stability and asymptomatic knee function were restored after IM nail removal, medial patellofemoral ligament repair, and left tibial tubercle transposition.

CONCLUSION

The optimal surgical approach for tibial IM nailing in patients with chronic patellar instability has not been described. Clinicians should be cognizant of the potential for worsening patellofemoral instability in these patients when using the medial parapatellar approach in the semiextended position.

Locked Plating versus Nailing for Proximal Tibia Fractures: A Multicenter RCT

OBJECTIVES

The main 2 forms of treatment for extraarticular proximal tibial fractures are intramedullary nailing (IMN) and locked lateral plating (LLP). The goal of this multicenter, randomized controlled trial was to determine whether there are significant differences in outcomes between these forms of treatment.

DESIGN

Multicenter, randomized controlled trial.

SETTING

16 academic trauma centers.

PATIENTS/PARTICIPANTS

108 patients were enrolled. 99 patients were followed for 12 months. 52 patients were randomized to IMN, and 47 patients were randomized to LLP.

INTERVENTION

IMN or lateral locked plating.

MAIN OUTCOME MEASUREMENTS

Functional scoring including Short Musculoskeletal Functional Assessment, Bother Index, EQ-5Dindex and EQ-5DVAS. Secondary measures included alignment, operative time, range of motion, union rate, pain, walking ability, ability to manage stairs, need for ambulatory aid and number, and complications.

RESULTS

Functional testing demonstrated no difference between the groups, but both groups were still significantly affected 12 months postinjury. Similarly, there was no difference in time of surgery, alignment, nonunion, pain, walking ability, ability to manage stairs, need for ambulatory support, or complications.

CONCLUSIONS

Both IMN and LLP provide for similar outcomes after these fractures. Patients continue to improve over the course of the year after injury but remain impaired even 1 year later.

Recurvatum Deformity in Proximal Tibial Fractures Treated With the Synthes Tibial Nail

Sagittal malalignment after intramedullary fixation of proximal third tibial shaft fractures has been described frequently, but almost every reported case involves a procurvatum deformity. We report 2 cases of recurvatum deformity of proximal third tibial shaft fractures where the Synthes EX tibial nail was used. The recurvatum deformity may have been induced by the shape of the nail, with its more distal Herzog curve relative to designs from other manufacturers. In proximal third tibial shaft fractures, tibial nails with distal Herzog curves may induce a recurvatum deformity that is not easily correctable. [Orthopedics. 2023;46(2):e129-e131.].

Suprapatellar Tibial Nailing: Future or Fad?

Over the last hundred years, there have been significant advancements in the way the Orthopaedic community treats tibial fractures. More recently, the focus of Orthopaedic trauma surgeons has been comparing the different techniques of insertion for tibial nails, specifically suprapatellar (SPTN) versus infrapatellar. The existing literature is convincing that there does not appear to be any clinically significant differences between suprapatellar and infrapatellar tibial nailing, with some apparent benefits of SPTN. Based on the current body of literature and our personal experience with SPTN, we believe the suprapatellar tibial nail will become the future for most tibial nailing procedures, regardless of fracture pattern. We have seen evidence of improved alignment in both proximal and distal fracture patterns, decreased radiation exposure and operative time, relaxation of the deforming forces, ease of imaging, and static positioning of the leg, which would be helpful for the unassisted surgeon, as well as no difference in anterior knee pain or articular damage within the knee between the two techniques.

Immediate Weight Bearing as Tolerated Is Safe Following Intramedullary Fixation of Extra-articular Metaphyseal Proximal Tibia Fractures (OTA/AO 41-A)

OBJECTIVES

To determine whether immediate weight bearing after intramedullary fixation of extra-articular proximal tibia fractures (OTA/AO 41A) results in change of alignment before union.

DESIGN

Retrospective Review.

SETTING

Level I and Level II Trauma Center.

PATIENTS/PARTICIPANTS

Thirty-seven patients with 37 proximal tibial fractures, all whom could bear weight as tolerated postoperatively. Eighteen fractures were OTA/AO 41-A2, and 19 were OTA/AO 41-A3.

INTERVENTION

Intramedullary nailing of extra-articular proximal tibia fractures.

MAIN OUTCOME MEASUREMENTS

Change in fracture alignment or loss of reduction.

RESULTS

The average change in coronal alignment at the final follow-up was 1.22 ± 1.28 degrees of valgus and 1.03 ± 1.05 degrees of extension in the sagittal plane. Twenty-five patients demonstrated excellent initial alignment, 10 patients demonstrated acceptable initial alignment, and 2 patients demonstrated poor initial alignment. Five patients demonstrated a change in alignment from excellent to acceptable at the final follow-up. No patient went from excellent or acceptable initial alignment to poor final alignment. Five patients required unplanned secondary surgical procedures. Two patients required return to the operating room for soft-tissue coverage procedures, 2 patients required surgical debridement of a postoperative infection, and 1 patient underwent debridement and exchange nailing of an infected nonunion. No patient underwent revision for implant failure or loss of reduction.

CONCLUSION

Immediate weight bearing after intramedullary fixation of extra-articular proximal tibia fractures (OTA/AO 41A) led to minimal change in alignment at final postoperative radiographs.

The semi-extended infrapatellar intramedullary nailing of distal tibia fractures: a randomized clinical trial

BACKGROUND

Malalignment is a common event during the intramedullary nailing (IMN) of distal tibia fractures (DTFs). Although it is reported that the semi-extended IMN techniques such as suprapatellar (SP) and parapatellar (PP) approaches may be superior in preventing malalignment, the application of these techniques is concerning owing to the intra-articular involvement. We thus developed an extra-articular semi-extended infrapatellar (SEIP) approach which utilizes the infrapatellar (IP) space while maintaining the knee in a semi-extended position. However, there are no studies on the safety and efficacy of SEIP in treating DTFs. Therefore, in this study, the SEIP technique was examined, particularly in terms of the potential alignment improvement of DTFs, and this technique was compared with the traditional hyperflexed infrapatellar (HFIP) procedure.

MATERIALS AND METHODS

This randomized clinical trial (RCT) compared IMN malalignment while correcting extraarticular and nondisplaced intra-articular DTFs between April 2018 and June 2021 using the HFIP and SEIP techniques at a level I trauma center in China. The study participants were clinically and radiographically examined for at least 12 months of follow-ups. Intraoperative fluoroscopy time, operation time, blood loss, hospitalization duration, functional ankle score, and complications were assessed as well.

RESULTS

Among the 88 recruited participants, 45 (51%) underwent traditional HFIP IMN and 43 (49%) underwent SEIP IMN. Malalignment occurred in 9 patients (20.0%) from the HFIP cohort and in 2 patients (4.7%) from the SEIP cohort (P value = 0.030). In addition, the SEIP IMN technique significantly reduced the intraoperative fluoroscopy time, operation time, and improved the postoperative ankle function compared to the HFIP IMN technique. However, the intraoperative blood loss, hospitalization duration, infection, delay union, and nonunion remained the same between the two cohorts.

CONCLUSIONS

In summary, we demonstrated that the SEIP IMN provides markedly enhanced alignment of extraarticular and nondisplaced intra-articular DTFs compared to the traditional HFIP IMN procedure. The described technique represents an effective option for IMN of DTFs.

Nail insertion points in semi-extended nailing of tibial fractures and their influence on alignment: A retrospective cohort study comparing two nail insertion techniques

INTRODUCTION

Semi-extended tibial nailing techniques include the extra-articular technique (EAT) and the patellar eversion technique (PET). These approaches differ regarding the exposure of the patellar retinaculum and the size of the surgical field. This study compared the postoperative alignment and intramedullary nailing entry points between the EAT and PET for tibial fractures.

PATIENTS AND METHODS

A total of 54 patients (aged ≥18 years) who had undergone intramedullary nailing by the EAT (n = 29) or PET (n = 25) for a tibial shaft fracture were evaluated. The intramedullary nailing entry point and postoperative alignment were measured, and the 1-year postoperative follow-up results were compared.

RESULTS

For the EAT and PET, the intramedullary nailing entry point was located at a mean distance of 4.04 mm medial to the optimal entry point and 0.27 mm lateral to the optimal entry point, respectively. The mean angular deformation observed in anteroposterior radiographs following surgery using the EAT and PET were 2.49° and 0.32° valgus, respectively.

CONCLUSION

The intramedullary nailing entry point affected postoperative alignment. Intramedullary nailing may result in malalignment while performing the EAT due to the interference of the patella at the time of nailing.

Investigating and defining outcomes of suprapatellar versus infrapatellar intramedullary nailing of tibial shaft fractures: a protocol for a pilot randomised controlled trial

Background

Anterior knee pain is often reported following intramedullary nailing of tibial shaft fractures. The aetiology remains unclear, but the surgical approach may play an important role. To date, no biomechanically validated method exists to assess patient outcomes specific to anterior knee pain in this cohort. The central aims of this study are to (1) evaluate the feasibility of a full-scale randomised controlled trial (RCT) investigating the influence of surgical approach on intramedullary nailing of tibial shaft fractures (suprapatellar versus infrapatellar nailing), (2) explore differences in clinical outcomes between the approaches, and (3) explore the development of a biomechanically validated methodology for assessing post-operative anterior knee pain and knee function specific to intramedullary nailing of tibial shaft fractures.

Methods

This pilot study will follow a prospective randomised controlled design at the Royal Adelaide Hospital and The Queen Elizabeth Hospital (South Australia). This study aims to recruit 60 patients between 18 and 60 years old who will be randomly assigned to either the suprapatellar or infrapatellar approach following a decision for intramedullary surgical fixation by the treating surgeon. All nails in this study will be Stryker T2 Alpha nails. Patients will undergo standard radiograph, magnetic resonance imaging, and clinical assessments in-line with their standard operative care, and complete a number of patient-reported and performance-based outcome measures. Performance-based outcome measures will be assessed utilising three-dimensional motion capture techniques. Follow-up time points are 3, 6, 12, and 18 months. Feasibility outcomes include ability to meet enrolment and retention metrics, compliance with all questionnaires and assessment procedures, and the occurrence of any adverse events. The primary clinical outcome is the incidence of anterior knee pain at 12 months after surgery.

Discussion

This study will establish the feasibility and inform the design of a large-scale RCT. Evaluation of all clinical data and patient outcomes will lead to the development of a new tool for assessing patient outcomes in this cohort. Limitations of the study include an unpredictable enrolment rate and loss to follow-up, small sample size, and the unknown ability of three-dimensional motion analysis to pick up the effects of anterior knee pain after tibial nailing.

This trial was prospectively registered on the 7 February 2020 on ANZCTR, ACTRN12620000109909.

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

BACKGROUND

Over the last 20 years, 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.

AIMS

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.

PATIENTS AND METHODS

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 six months 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.

RESULTS

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, 9.8 minutes; 95% CI, 5.7 to 14.0 minutes; 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.

CONCLUSIONS

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.

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.

A Review of Proximal Tibia Entry Points for Intramedullary Nailing and Validation of The Lateral Parapatellar Approach as Extra-articular

Tibial shaft fractures are the most common long bone injury and are often treated surgically in an attempt to minimize complications. Although treatment options for tibial shaft fractures vary based on factors including open injury, severity of fracture, and soft tissue status, intramedullary nailing in adults has emerged as the preferred definitive option for stabilization. Therefore, the primary purposes of this review and cadaveric study were to evaluate the entry points for reamed tibial nails and the risks, benefits, and advantages of each approach. Due to concerns of violating the joint capsule and the generalized applicability to everyday practice of the extra-articular lateral parapatellar semi-extended technique, the secondary goal of this manuscript was to evaluate whether an intramedullary tibial nail can be consistently placed extra-articularly using the lateral parapatellar technique described by Kubiak et al. and generalizability to surgeons of varying experience.

The Clamshell Osteotomy for Diaphyseal Malunion in Deformity Correction and Fracture Surgery

Diaphyseal malunion poses a great challenge for the orthopedic surgeon, and an inundation of morbidity for the patient. Diaphyseal malunion can cause altered gait, adjacent joint osteoarthritis and body dissatisfaction. This problem is fraught with complications without surgical intervention. There is a myriad of options for the management of a diaphyseal malunion. The clamshell osteotomy was engendered to ameliorate the difficulty in managing this issue. This technique is a viable option to correct diaphyseal malunion about the femur and tibia. Recently, the indications of a clamshell osteotomy have been expanded to function as a derotational or shortening osteotomy.

Tibial alignment following intramedullary nailing via three approaches

PURPOSE

The purpose of this study is to evaluate the incidence of malalignment in patients undergoing IMN for tibial shaft fractures treated with the extra-articular lateral parapatellar, suprapatellar, and infrapatellar approaches.

METHODS

A retrospective review of an institutional trauma database was completed at a single level 1 trauma academic medical centre. Quality of reduction was assessed using the following three parameters: (1) < 10°of angulation in orthogonal radiographic views (2) < 5 mm of displacement between the major fracture fragments (3) < 5 mm of gap between the major fracture fragments. A good reduction was one that met all 3 criteria, an acceptable reduction met 2 criteria, and a bad reduction met one or none of the criteria. All patients treated consecutively for tibial shaft fractures between June 1, 2019 and June 1, 2020 were identified. The final cohort included 57 tibia fractures in 56 patients. Of the 57 tibia fractures, 8 (14%) were proximal third, 32 (56%) were middle third, and 17 (30%) were distal third fractures.

RESULTS

We found no significant difference in angulation, displacement, or gapping with respect to surgical approach utilized or location of fracture (proximal or distal tibia fractures) on one-way ANOVA. Quality of reduction was rated as "good" in 48 (84%) of the cases (19 supra, 13 infra, and 16 lateral). Nine reductions (16%) met only two of the three reduction quality criteria and were considered acceptable reductions. These included 2 suprapatellar (1 > 5 mm displacement, 1 > 5 mm gapping), 4 infrapatellar (4 > 5 mm displacement), and 3 lateral extra-articular parapatellar (2 > 5 mm displacement and 1 > 5 mm gapping). No reductions were determined to be bad according the Baumgaertner et al. criteria. There was no significant difference in the rate of combined fibula fractures or the rate of fibular fixation between the three cohorts.

CONCLUSIONS

In conclusion, no significant difference was found in fracture reduction angulation, displacement, and gapping in patients treated with an IMN with respect to approach for diaphyseal or metadiaphyseal tibial shaft fractures.

Difference in Pain, Complication Rates, and Clinical Outcomes After Suprapatellar Versus Infrapatellar Nailing for Tibia Fractures? A Systematic Review of 1447 Patients

OBJECTIVES

To assess the effectiveness of suprapatellar (SP)-nailing versus infrapatellar (IP)-nailing of tibia fractures in anterior knee pain, complications (retropatellar chondropathy, infection, and malalignment) and physical functioning and quality of life. A clinical question-driven and thorough systematic review of current literature is provided.

DATA SOURCE

PubMed and Embase databases were searched for studies published between 2010 and 2020 relating to SP and IP-nailing of tibia fractures. The study is performed in concordance with PRISMA-guidelines.

STUDY SELECTION

Studies eligible for inclusion were randomized controlled trials, prospective and retrospective observational studies reporting on outcomes of interest.

DATA EXTRACTION

Data extraction was performed independently by 2 assessors. Methodological quality and risk of bias was assessed according to the guidelines of the McMaster Critical Appraisal.

DATA SYNTHESIS

Continuous variables are presented as means with SD and dichotomous variables as frequency and percentages. The weighted mean, standardized weighted mean differences, and 95% confidence interval were calculated. A pooled analysis could not be performed because of differences in outcome measures, time-points, and heterogeneity.

RESULTS

Fourteen studies with 1447 patients were analyzed. The weighted incidence of anterior knee pain was 29% after SP-nailing and 39% after IP-nailing, without reported significance. There was a significant lower rate of malalignment after the SP-approach (4% vs. 26%) with small absolute differences in all planes. No substantial differences were observed in retropatellar chondropathy, infection, physical functioning, and quality of life.

CONCLUSIONS

This systematic review does not reveal superiority of either technique in any of the respective outcomes of interest. Definitive choice should depend on the surgeon's experience and available resources.

Extreme Nailing or Less Invasive Plating of Lower Extremity Periarticular Fractures

Periarticular fractures of the lower extremity can be difficult injuries to stabilize effectively. Modern advances in technique and implant design now allow many of these fractures to be fixed with an extreme intramedullary nail. When nailing is not possible, less invasive plating through percutaneous incisions is a reliable option. The decision to perform extreme nailing is multifactorial and is based on the fracture pattern, the condition of the soft tissues, the medical condition of the patient, and the importance of earlier or immediate weightbearing.

Comparison between intramedullary nailing and minimally invasive plate osteosynthesis for tibial shaft fractures

INTRODUCTION

Intramedullary nailing (IMN) is currently considered the gold standard in the surgical treatment of tibial shaft fractures in adult patients. In this case-control comparative study, we aimed to compare the efficacy of minimally invasive plate osteosynthesis (MIPO) and IMN in treating tibial shaft fractures.

MATERIALS AND METHODS

The clinical and radiological outcomes, such as a modified trauma scale, operation time, fracture healing, rate of re-operation, and complications such as malunion, nonunion, shortening, and infection were assessed between IMN and MIPO for the treatment of tibial shaft fractures.

RESULTS

Seventy-three skeletally mature patients who underwent IMN (group I) or MIPO (group M) for a closed extra-articular tibial shaft fracture (AO/OTA type 42) from June 2010 to May 2016 were retrospectively reviewed. The mean age was 51.16 (18~79) years, and the mean follow-up period was 22 (12~50) months. Bony union was achieved in all cases but one for each group - group I (35 cases) and group M (36 cases) (p > 0.05). Mean callus formation was observed in 12 (8 - 16) weeks in both groups (p > 0.05). There was no significant difference in operative time, hospital stay, bone healing, and the rate of complications among the two groups (p > 0.05). There was also no postoperative difference in functional evaluation between the two methods (p > 0.05).

CONCLUSIONS

No discrepancy was found in radiological and clinical outcomes between IMN and MIPO for tibial shaft fractures. It can be concluded that both IMN and MIPO are equally effective treatment modalities for tibial shaft fractures.

Intramedullary tibial nailing using infrapatellar and suprapatellar approaches: A systematic review and meta-analysis

INTRODUCTION

Intramedullary nailing of diaphyseal tibial fractures has become the gold standard method of fixation with high rates of union and low complication rates reported. The suprapatellar (SP) approach may have many advantages over the traditional infrapatellar (IP) approach. Controversy exists due to potential damage to the patellofemoral joint leading to persistent anterior knee pain. This systematic review and meta-analysis aims to evaluate the clinical and procedural outcomes of the SP approach in comparison to the traditional IP approach.

METHOD

In this PRISMA compliant systematic review and meta-analysis, five databases including MEDLINE, EMBASE, Web of Science, Cochrane Library and CINAHL were searched from inception until May 2020. Randomised controlled trials (RCTs) and comparative observational studies involving adults with tibial fractures treated with intramedullary nail fixation using either the suprapatellar or infrapatellar approach were included. Data extracted included demographics, functional knee scores, fluoroscopy exposure, insertional accuracy and adverse events. The primary outcome was validated functional knee scores. Risk of bias was calculated using the Cochrane risk of bias tool version 2 (RoB 2) and Newcastle-Ottawa Scale (NOS).

RESULTS

In total 16 studies were included consisting of 5 RCTs and 11 comparative observational studies. This included 1750 total operations with 810 in the SP group and 940 in the IP group. Meta-analysis was performed on the studies where appropriate data was reported. The SP approach demonstrated superior Lysholm scores (Mean Difference (MD) 5.63 [95% Confidence Interval (CI): 2.81 to 8.44]), reduced fluoroscopy times (MD -38.12 sec [95% CI: -47.96 to -28.28]) and increased entry point accuracy (Standard Mean Difference (SMD) -0.90 [95% CI: -1.22 to -0.59]). No differences in complication rates or blood loss were found.

CONCLUSION

Based on the data presented in this review, intramedullary nailing of the tibia using the SP approach demonstrates superior Lysholm knee scores, greater entry point accuracy and reduced fluoroscopy exposure with equivalent risk of developing complications when compared to the IP approach.

Semi-extended intramedullary nailing of the tibia using an infrapatellar approach: a retrospective cohort study

PURPOSE

The semi-extended tibial intramedullary nailing method would enable easier and improved reductions for tibial fractures as well as facilitate fluoroscopic imaging; however, its in-articular nature remains controversial. The aim of this study was to compare the clinical and functional outcomes of the semi-extended infrapatellar (SEIP) approach and hyper-flexed infrapatellar (HFIP) approach for intramedullary nailing to treat tibial shaft fractures.

METHODS

This study involved the retrospective analysis of the medical records of patients with tibial shaft fractures that were fixed through either the SEIP approach or the HFIP approach of intramedullary nailing and who were admitted to a level 1 trauma centre. The minimum patient follow-up period was 12 months and the clinical and functional outcomes were estimated at the 12-month visit.

RESULTS

Of the 80 patients whose medical records were analyzed, 40 (50%) underwent SEIP nailing and the remaining 40 (50%) underwent the traditional HFIP nailing. Compared with the HFIP group, patients in the SEIP group had a higher Lysholm knee score (median, 92 [interquartile range, 88-95] vs median, 88 [interquartile range, 81-92]; p = .01), a shorter intra-operative fluoroscopy time (median, 93 [interquartile range, 78-105] s, vs median, 136 [interquartile range, 110-157] s; p < .001), and operation time (mean, 88.1 [SD, 17.8] min vs mean, 98.7 [SD, 19.3] min; p = .01). The VAS score was significantly lower in the SEIP group (median, 0; interquartile range, 0-0) than in the HFIP group (median, 0; interquartile range, 0-2) (p = .03). There were two cases (5%) in the SEIP group and 10 cases (25%) in the HFIP group of moderate AKP (p = .03). Meanwhile, there was no significant difference in malalignment, nonunion, delayed union, infection, and other complications, as well as SF-36 physical and mental scores.

CONCLUSION

We found that the SEIP approach to tibia intramedullary nailing was superior to the HFIP approach based on the intra-operative and post-operative outcomes. Thus, this novel technique provides an infrapatellar option for semi-extended tibial nailing.

Comparison of Infrapatellar and Suprapatellar Approaches for Intramedullary Nail Fixation of Tibia Fractures

OBJECTIVE

To assess clinical, radiographic, and functional outcomes after intramedullary nail (IMN) fixation of tibia fractures with an infrapatellar approach compared to a suprapatellar approach.

DESIGN

Retrospective chart review.

SETTING

Level 1 trauma center.

PATIENTS/PARTICIPANTS

Two hundred four patients with 208 tibia fractures treated with intramedullary nailing between 2008 and 2018.

METHODS

A retrospective chart review of tibia fractures was conducted. The clinical and functional outcomes of tibia fractures treated with IMN were compared between groups treated with an infrapatellar approach versus a suprapatellar approach. Multivariate models were created to control for confounding demographic, comorbidity, and injury-related confounders.

MAIN OUTCOME MEASUREMENTS

Outcome measures included nonunion, malunion, and infection. Subjective functional patient outcomes were assessed using pain interference and physical function Patient-Reported Outcome Measurements Systems scores.

RESULTS

There were 101 patients treated with infrapatellar nailing (49%) and 107 patients treated with suprapatellar nailing (51%). On multivariate analysis, suprapatellar nailing was independently associated with decreased risk of malunion (adjusted odds ratio, 0.165; 95% confidence interval, 0.054-0.501; P = 0.001) and decreased risk of postoperative knee pain (adjusted odds ratio, 0.272; 95% confidence interval, 0.083-0.891; P = 0.032). There was no difference in the rate of nonunion (P = 0.44), infection (P = 0.45), or Patient-Reported Outcome Measurements Systems pain interference or physical function scores.

CONCLUSIONS

Suprapatellar IMN fixation of tibial shaft fractures is independently associated with lower risk of malunion and postoperative knee pain compared to the infrapatellar approach. However, there are no functional differences between approaches.

A comparison of anterior knee pain, kneeling pain and functional outcomes in suprapatellar versus infrapatellar tibial nailing

INTRODUCTION

Anterior knee pain and kneeling pain are some of the most common complications following intramedullary nailing of tibial shaft fractures. With the increased uptake of suprapatellar nailing at our institution, we undertook a service evaluation to assess anterior knee pain and kneeling pain in patients who underwent the suprapatellar tibial nailing technique compared with the infrapatellar approach.

METHODOLOGY

Data from all consecutive intramedullary tibial nailing operations between January 2014 and July 2017 were analysed from a prospectively collected database. All acute diaphyseal fracture nailing procedures were included. All patients were reviewed between six-month and four-year post-operation. Each patient was asked to complete a standardised questionnaire with three main outcome measures: pain on kneeling, presence of anterior knee pain and the severity of pain.

RESULTS

After exclusions, a total of 148 patients were identified. A total of 102 responses were received, 41 in the infrapatellar group (73.2%) and 61 in the suprapatellar group (66.3%). A longer time from surgery to telephone follow-up response was noted in the infrapatellar group: 32.4 months (interquartile range, 16.1) vs. 19.3 months (interquartile range, 17.4), p < 0.001. A trend towards lower reported anterior knee pain was noted in the suprapatellar group (67.9% VS 53.7%). Most patients reported mild or no pain on kneeling, with no significant difference between the two groups. There was also no significant difference in severity of knee pain between the two groups and no significant effect on the Kujala score.

CONCLUSION

With the comparable pain outcomes between the two groups, our analysis supports the continued use of the suprapatellar tibial nailing technique for tibial shaft fractures at our institution.

[Treatment of tibial shaft fracture with intramedullary nailing fixation in semi-extended position via extraarticular parapatellar approach]

Objective

To investigate the effectiveness of intramedullary nailing fixation in semi-extended position via extraarticular parapatellar approach for tibial shaft fracture.

Methods

Between July 2018 and September 2019, 22 patients with tibial shaft fracture treated with intramedullary nailing fixation in semi-extended position via extraarticular parapatellar approach. There were 15 males and 7 females, with an average age of 46.4 years (range, 25-68 years). The fractures were caused by falling in 7 cases, by traffic accident in 14 cases, and by a heavy object in 1 case. Sixteen patients were closed fractures and 6 were open fractures. According to the AO classification, there were 4 cases of 42-A1 type, 2 cases of 42-A2 type, 3 cases of 42-A3 type, 3 cases of 42-B2 type, 4 cases of 42-B3 type, 2 cases of 42-C1 type, 3 cases of 42-C2 type, and 1 case of 42-C3 type. Twenty cases complicated with fibular fractures. The time from injury to operation was 2-15 days (mean, 7.5 days). The fracture healing time, complications, the incidence of anterior knee pain during the follow-up were observed; and knee joint functions were evaluated by Lysholm score at last follow-up.

Results

The operation time was 50-140 minutes (mean, 85 minutes). Two cases experienced incision exudation which healed after symptomatic treatment. The incisions of other patients healed by first intention. All patients were followed up 8-23 months (mean, 14.9 months). X-ray films reexamination showed that all fractures healed with the healing time of 12-20 weeks (mean, 14.4 weeks). Four patients (18.18%) experienced the anterior knee pain. No patellofemoral instability was observed during the follow-up period. Lysholm score of knee function was 85-100 (mean, 94.3) at last follow-up.

Conclusion

Application of the intramedullary nailing fixation in semi-extended position via extraarticular parapatellar approach is effective for tibial shaft fractures, which can not only realize the effective fixation of the fracture, but also avoid the adverse factors including re-displacement and anterior knee pain in the application of the intramedullary nailing fixation via the sub-patellar approach.

Intramedullary Nailing Versus Plating for Proximal Tibia Fractures: A Systematic Review and Meta-analysis

INTRODUCTION

Extra-articular proximal tibia fractures make up to one-tenth of all tibia shaft fractures. Treatment options include conservative, nailing, plating and external fixation. There is no consensus on which method is superior if the patient is to be managed surgically.

MATERIALS AND METHODS

We conducted a systematic review and meta-analysis to know which definitive surgical treatment option (nailing or plating) is better for extra-articular proximal tibia fracture. We used search engines like PubMed, Embase, Scopus, Ovid Medline and Google Scholar to find articles comparing the results of nailing versus plating. We could identify only 4 articles regarding this and data was extracted and meta-analysis was done.

RESULTS

Delayed union was common in the nailing group with odds ratio of 8.29 favoring the plating group (95% CI 1.77, 38.80, p = 0.007) while malunion showed no difference in both groups. Rate of infection was higher in the plating group while anterior knee pain was common in the nailing group with odds ratio of 5.54 favoring the plating group (95% CI 1.49, 13.88, p = 0.008). Range of motion showed no difference between both groups, fractures in the nailing group united early and the difference was significant (p = 0.005, odds ratio  - 4.48) (95% CI  - 8.29,  - 1.47).The surgical duration was less in the nailing group but was not significant.

CONCLUSION

Considering lesser time for union, early weight bearing, lower chances of infection and lesser surgical duration, nailing seems to be more promising for extra articular proximal tibia fractures. Further research is required on this topic to provide a definitive evidence.

Comparison between infrapatellar and suprapatellar approaches for intramedullary nailing for the fractures of the tibial shaft

INTRODUCTION

This study aimed to compare the outcomes at the clinical and functional levels of suprapatellar (SP) and infrapatellar (IP) approaches for intramedullary nailing in treating tibial shaft fracture.

METHODS

Patients who underwent tibial shaft fracture intramedullary nailing by the SP approach or IP approach in a trauma center were retrospectively reviewed. The demographics, intraoperative fluoroscopy time, operation time, blood loss, irrigation volume, postoperative X-ray alignment, and complications of patients were compared between the two groups under different approaches. Lysholm knee score, visual analog score (VAS), and incidence of anterior knee pain (AKP) were assessed 1 year after surgery.

RESULTS

The study finally included well-documented 81 patients (38 SP versus 43 IP). The SP group exhibited significantly shorter intraoperative fluoroscopy time than that of the IP group (81.7 ± 14.5 s vs. 122.0 ± 24.3 s, P < 0.001). Both aspects recorded a precise reduction of the fracture: angulation (2.1 ± 1.2° vs 3.1 ± 1.5°, P < 0.05) and translation (0.6 ± 0.8 mm vs 1.4 ± 1.5 mm, P < 0.05) in the coronal plane in the SP group. However, the sagittal plane recorded no such change (P > 0.05). The Lysholm knee score was higher in the SP group than that of the IP group (87 ± 8 vs. 80 ± 15, P < 0.05). The SP group displayed an evidently lower average VAS score than that of the IP approach group (0.3 ± 0.8 vs 1.3 ± 1.4, P < 0.001). Six cases (16%) in the SP group and 16 cases (37%) in the IP group experienced AKP 1-year post-operation (P < 0.05). As far as complications are concerned, neither group showed any significant difference (P > 0.05).

CONCLUSION

Compared with the IP approach, the application of intramedullary nailing through the SP approach in treating tibial shaft fractures can effectively shorten the intraoperative fluoroscopy time, correct coronal plane angulation and translation deformity, reduce the incidence of AKP and improve postoperative function.

Comparison of suprapatellar versus infrapatellar approaches of intramedullary nailing for distal tibia fractures

Background

This study aimed to analyze and compare the clinical and functional outcomes of distal tibia fractures treated with intramedullary nailing (IMN) using the suprapatellar (SP) and infrapatellar (IP) surgical approaches.

Methods

A retrospective analysis was performed in 63 patients with distal fractures that were treated with IMN between August 2014 and August 2018. A total of 27 and 36 patients underwent IMN using the SP and IP techniques, respectively. The surgical time, blood loss, closed reduction rate, rate of adjuvant reduction technique, fracture healing time, and complications were reviewed in this study. Anterior knee pain was assessed using the visual analog scale. The Lysholm Knee Scoring Scale and American Orthopaedic Foot and Ankle Society (AOFAS) scale were used as clinical measurements.

Results

A total of 63 patients, with a minimum follow-up of 12 months, were evaluated. The average surgical time, blood loss, rate of adjuvant reduction technique, closed reduction rate, fracture healing time, and Lysholm Knee Scoring Scale score were insignificantly different (P > 0.05) between the two groups. However, the SP approach was superior to the IP approach in terms of pain score, AOFAS score, and fracture deformity rate (P < 0.05).

Conclusions

In the treatment of distal tibia fractures, the SP IMN technique is associated with a significantly higher functional outcome, lower knee pain, and lower rate of fracture deformity than the IP IMN technique.

Anterior knee pain and functional outcome following different surgical techniques for tibial nailing: a systematic review

Purpose

The aim of this systematic review was to compare knee pain and function after tibial nail insertion through an infrapatellar, semi-extended and suprapatellar technique.

Methods

A search was carried out to identify articles with an exact description of the method used for insertion of the tibial nail and description of the outcome parameters (knee pain or function). Data on study design, population, rate and severity of anterior knee pain and function scores were extracted. Pooled rates and scores were calculated.

Results

67 studies with 3,499 patients were included. The pooled rate of patients with anterior knee pain was 38% (95% CI 32–44) after nail insertion through an infrapatellar approach and 10% (95% CI 1–26) after insertion through a suprapatellar approach. Pooled analysis was not possible for the semi-extended technique. Knee pain scores as measured by visual analogue score (0–10) ranged from 0.2 (95% CI − 0.1–0.5) for general knee pain to 3.7 (95% CI 1.3–6.1) for pain during kneeling. Pooled estimates for the Lysholm score were 87 points (range 77–97) for the infrapatellar technique and 85 points (range 82–85) for the suprapatellar technique. Iowa Knee scores were 94 (range 86–96) and Anterior Knee Pain Scale scores were 76 (range 75–80) after infrapatellar nail insertion.

Discussion

Depending on the technique used, the proportion of patients with knee pain after tibial nailing varied between 10 and 38%. The actual measured knee pain scores were, however, surprisingly low. Knee function was good for both the infra- and suprapatellar technique.

Tibial Intramedullary Nail From a Suprapatellar Approach in a Semi-Extended Position

An intramedullary nail is a common and reliable treatment option for diaphyseal tibial fractures. One such approach for this technique is suprapatellar. This video shows the surgical technique of a tibial nail through a suprapatellar approach in a semi-extended position in a 22-year-old man with a distal third tibial shaft fracture.

Suprapatellar nailing in proximal third tibial fractures - Clinicoradiological outcome

AIMS AND OBJECTIVES

To evaluate the clinical and radiological outcome of proximal third tibia fractures managed by suprapatellar nailing with a minimum follow-up of 12 months.

METHODOLOGY

In our retrospective cohort study of 43 consecutive proximal third tibia fractures from January 2015 to September 2018 treated with intramedullary nailing through suprapatellar approach in semiextended knee position were included. The patients were followed up regularly at 6 weeks, 3 months, 4.5 months, 6 months, 12 months and every 6 months thereafter. At each visit patients were assessed for union, shortening and rotational alignment. The clinical outcome was analysed using Lower Extremity Functional Scale (LEFS) and anterior knee pain. The radiological outcomes are analysed by evaluating the radiographs for progression of fracture union and tibial alignments.

RESULTS

After fulfilling the exclusion and inclusion criteria, 43 out of 60 consecutive proximal third tibia fracture were included in the study with an average age of 38.4 years (20-71 years), follow up of 20.4 months (12-45 months) after the index procedure. The radiological union was achieved in 7.3 months (4-13 months). At the end of 1 year follow up, the average LEFS was 89.4% (60%-95%). 4 patients had Malunion - with 1 valgus and 3 anterior angulations, 8 delayed unions and 1 non-union (with bone loss- which required bone grafting). All the fractures united eventually. No incidence of anterior knee pain.

CONCLUSION

We recommend suprapatellar nailing in proximal third tibial fractures when meticulously performed using the current surgical principles and techniques with proper implant selection. It results in excellent clinical and radiological outcomes with minimal complications when compared to other modalities of management. Suprapatellar nailing is a viable option for proximal third tibia fractures due to its inherent advantages of positioning, perfect nail entry and placement. Additionally, noteworthy absence of anterior knee pain is an additional benefit of this technique.

[Current treatment strategies for lower leg fractures in adults]

Shaft fractures of the tibia and fibula mainly affect younger patients and are therefore of great socioeconomic importance. Due to the high proportion of high-energy direct trauma mechanisms and the thin soft tissue covering layer of the ventromedian tibia, open factures occur in up to 39%. A structured diagnostic and therapeutic approach is essential for successful treatment. Reamed intramedullary nailing is currently the gold standard surgical procedure. The suprapatellar approach, representing an interesting alternative to the popular infrapatellar approach, postoperative complications, such as anterior knee pain as well as the management of non-unions are discussed in this article. Furthermore, the indications and the application of minimally invasive plate osteosynthesis (MIPO) and external fixators are described. Every trauma surgeon should be familiar with the etiology and the surgical treatment of compartment syndrome. A firm knowledge of the classifications of open and closed soft tissue injury is mandatory.

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

INTRODUCTION

This 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.

METHODS

After 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.

RESULTS

Differences 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).

CONCLUSION

Based 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.

Intramedullary tibia nailing with external fixation

PURPOSE

This study introduces an intramedullary nailing technique with external fixation and aims to determine the safest position of Schanz screws for this technique.

METHODS

Patients undergoing intramedullary nailing were evaluated by computed tomography to assess the anteroposterior (AP) length of the medullary canal and the distance between the posterior cortex and the posterior border of the nail at the level of interest in the proximal and distal tibia. In this cadaveric study, screws were inserted at the level of interest, followed by a determination of the anatomical relationship between inserted screws and nearby neurovascular structures.

RESULTS

The safe area for inserting Schanz screws in the medial to lateral direction in the proximal tibia was found to be 1.5-4.5 cm distal to the knee joint line on the AP view, 1 cm anterior to the posterior cortex at the distal 4.5 cm level, and ≤ 24 mm from the posterior cortex on the lateral view. In males, the area 1.5-3.0 cm proximal to the tibial plafond and 0.5 cm anterior to the posterior cortex on the lateral view was found to be a safe zone. However, in females, the safe zone was defined as an area 1.5 cm proximal to the tibial plafond and just anterior to the posterior cortex.

CONCLUSION

This study defined the safe zones of Schanz screws for intramedullary nailing with an external fixator. These safe zones would be helpful for external fixation during intramedullary tibia nailing.

Pearls and Pitfalls With Intramedullary Nailing of Proximal Tibia Fractures

Intramedullary fixation of proximal tibia fractures remains a challenging surgical technique, with malalignment reported as high as 84%. The pull from the extensor mechanism, the hamstring and iliotibial band, in addition to the lack of endosteal fit from the nail, has made surgical fixation of these fractures difficult. Commonly held principles to reduce angular deformity include ensuring adequate imaging, obtaining an optimal start and trajectory for the implant, and obtaining and maintaining a reduction throughout the duration of the procedure. Some adjunctive techniques to assist in the application of these principles include use of a semiextended technique, clamping, blocking screws/wires, and unicortical plates. Understanding the challenges involved in intramedullary nailing of proximal tibia fractures and considering a wide array of techniques in the orthopaedic surgeon's armamentarium to combat these challenges is important.
