Ilizarov fixator as salvage procedure after frustrating arthrodesis using intramedullary nailing - is there a chance of consolidation?

INTRODUCTION: Arthrodesis of the tibiotalar and subtalar joints is a salvage procedure that has been used successfully for years. Treatment options include internal procedures and external procedures. Retrograde intramedullary nailing is considered a safe procedure with a high degree of stability and comfort. Nevertheless, there are cases in which this internal arthrodesis fails and another procedure must be considered. Ilizarov fixator treatment could be a solution for those patients in whom intramedullary nailing has failed. Even if it means another surgical revision - is it possible to finally achieve consolidation with this method? MATERIALS AND METHODS: In this single-center, retrospective study all documents of patients who underwent tibiotalar and subtalar joints fusion using the Ilizarov external fixator at our institution from 2003 to 2023 as secondary treatment after frustrated first arthrodesis using an intramedullary nail were reviewed. Nineteen patients (17 men and 2 women), with an average age of 55.7 (standard deviation (SD) 8.7, range 34-75) years were included. RESULTS: On average, 1.7 (SD 1.3, range 1-6) arthrodesis attempt were performed before final Ilizarov fixator arthrodesis. The average time spent in the Ilizarov fixator was 19 (SD 4, range 14-29) weeks. In seven cases (36.8%), both the tibiotalar and subtalar joints received bony consolidation in the end. CONCLUSION: If patients have undergone fusion of the tibiotalar and subtalar joints with a retrograde nail and this fails, it is difficult to achieve complete consolidation in the further course. A further attempt at arthrodesis using an Ilizarov fixator is possible, but the overall results are also poor. This procedure must therefore be seen as a last resort before amputation.

Metaizeau technique in stabilizing Monteggia equivalent 1b associated proximal radial physeal injury in a rural setting: a case report.

Introduction: The Monteggia equivalent type 1b fracture, consisting of an ulnar shaft fracture and radial head dislocation, is a rare condition first described by Giovanni Battista Monteggia. The Metaizeau technique, emphasizing percutaneous intramedullary fixation to preserve bone healing and prevent growth plate damage, has gained prominence in managing these fractures. Case report: A 10-year-old boy presented with left forearm pain, swelling, and deformity following a fall while playing football. X-rays revealed a proximal fourth ulnar fracture with dorsal and lateral angulation, along with a proximal radial metaphyseal fracture showing anterior rotation and physeal extension. This fracture pattern resembled a Monteggia fracture type III but differed in the lateral proximal radial disruption via a Salter-Harris type II fracture rather than radial epiphysis dislocation. Satisfactory reduction achieved for ulna was managed with standard nailing system but could not be achieved for radial physeal injury, which was managed with Metaizeau technique. Discussion: Type 1b Monteggia equivalents involving a Salter-Harris type 2 fracture of the proximal radius with an associated proximal ulnar fracture, adherence to Monteggia fracture reduction principles is vital. Closed reduction and internal fixation are preferred treatments, with the Metaizeau technique offering advantages such as minimal invasiveness and avoidance of implant-related complications. The Metaizeau technique is particularly beneficial for displaced radial neck fractures in children, providing stable fixation while preserving the fracture environment necessary for optimal healing. Conclusion: In cases of Monteggia fracture equivalents, most proximal radial fractures typically reduce to an acceptable level following ulnar reduction. However, proximal radial physeal fractures may require specific attention to achieve satisfactory reduction. The Metaizeau technique, commonly employed in the management of isolated radial neck fractures, can be utilized to achieve this reduction to an acceptable level.

Exploring Knee Flexion Techniques in Tibial Nailing: A Comparative Study of Two Different Methods Knee Flexion Techniques in Tibial Nailing.

BACKGROUND: Tibial fractures, particularly diaphyseal fractures, are common and can result in prolonged non-weight-bearing periods, especially in older adults. Intramedullary nailing has become the standard treatment, offering early weight-bearing and improved functional outcomes. This study aims to compare the efficacy and safety of two knee flexion methods - Method A (using an adjustable triangular frame) and Method B (Seyhan method) - in tibial nailing procedures. MATERIAL AND METHODS: A prospective randomized controlled trial was conducted with 90 adult patients aged 18-70 requiring intramedullary nailing for isolated closed tibial fractures. Method A utilized an adjustable triangular frame, allowing various degrees of knee flexion. In Method B (Seyhan method), knee flexion was achieved by leg sloping on the operation table with a cushion pillow under the distal thigh. RESULTS: In terms of complication rates, a key finding was a significantly higher incidence of edema in Method B compared to Method A. The results indicated minor differences in satisfaction levels, with a slightly higher percentage of 'Well Satisfied' and a higher dissatisfaction rate in Method B. However, these variations in surgeon satisfaction did not reach statistical significance. CONCLUSIONS: 1. The Seyhan method and the adjustable triangular frame were compared in our study, with the latter showing advantages in terms of ease of use and reduced complications. 2. While complications like knee pain were observed in some cases, the triangular frame showed superior results in surgical efficiency and patient outcomes. 3. Further research is needed to confirm these findings and explore specific scenarios where each method may excel.

Efficacy and safety of carbon fiber retrograde intramedullary nailing in tibio-talar-calcaneal fusion: a single-centre retrospective study.

INTRODUCTION: Tibio-talar-calcaneal (TTC) fusion is a salvage procedure designated for treating various severe hindfoot pathologies. While traditional methods have been effective, the advantage of carbon fiber (CF) retrograde intramedullary nailing (RIMN) presents a potentially superior technique. This study evaluates the efficacy and safety of CF RIMN in TTC fusion, focusing on union rates, complication rates, and patient-reported outcomes. MATERIALS AND METHODS: Conducted as a single-center, retrospective study, this research involved 21 patients who underwent TTC with CF RIMN from 2015 to 2021. Patient selection excluded those with active infections or those needing significant bone allografts. Patient follow-up was conducted at multiple intervals postoperatively, with a minimum follow-up of 24 months, assessing for union complications and using tools like the VAS, SF12, and AOFAS for patient-reported outcomes. RESULTS: The study observed a 90% union rate among patients. Complication rates included a 14% incidence of iatrogenic fractures to the anterior tibial cortex and 19% postoperative complications. Significant improvement was noted in VAS scores but not in SF12 and AOFAS scores. The use of 200 mm RIMN was identified as requiring careful consideration due to associated complications. CONCLUSION: CF RIMN in TTC fusion demonstrates a high union rate with notable complications. The significant improvement in VAS scores indicates patient satisfaction, but the lack of statistical significance in SF12 and AOFAS scores warrants attention. The findings advocate for the cautious use of 200 mm RIMN and highlight the need for further research, suggesting prospective, multicenter studies to validate these findings and explore long-term outcomes. LEVEL OF EVIDENCE: III.

Rotatory malunion following antegrade intramedullary femoral nailing for femoral shaft fractures: incidence and risk factors.

DESIGN: Retrospective study. SETTING: Level I academic Trauma Center. PATIENT SELECTION CRITERIA: Adult patients with femoral shaft fractures in which a bilateral computed-tomography (CT) scan of both femurs was performed, with a two years minimal follow-up. OUTCOME MEASURES AND COMPARISONS: Criteria related to the patient and the fracture were studied. We fixed the following angles, i.e. 10° and 15°, as references for calculating the RM.

Head-Shaft Angle Influences Isometric Shoulder Strength Levels after Intramedullary Nailing of Proximal Humerus Fractures: A Pilot Study.

BACKGROUND: Proximal humerus fractures are common fractures of the elderly population which can lead to long-term compromise of a patient's shoulder function. Closed reduction and internal fixation with intramedullary nailing is a well-established surgical technique yielding good outcomes, as perceived by patients, obtained via Patient-Reported Outcome Measures, and objectified by clinical shoulder testing. Apart from conventional range-of-motion testing and clinical shoulder tests, strength testing of the shoulder is a yet-neglected but meaningful and standardizable outcome parameter. In this study, isometric shoulder strength is evaluated in relation to fracture morphology/postoperative reduction quality as well as with patient-reported outcomes. METHODS: 25 patients (mean age 73.2 ± 10.5 years) underwent isometrics strength-testing of the shoulder joint in the scapular plane (abduction) as well as in the sagittal plane (flexion) as well as hand-grip strength-testing at 4.5 ± 1.88 years follow-up. Pre- and postoperative radiographs were analysed. Patients completed ASES and CMS questionnaires. RESULTS: Patients exhibited a decrease in abduction and flexion force (-24.47% and -25.30%, respectively, p < 0.001) using the contralateral, uninjured arm as reference. Abduction force tended to be decreased in three- and four-part fractures. Patient satisfaction correlated negatively with the relatively reduced force of the affected arm. Varus-angulated humeral heads produced significantly lower abduction force output than valgus- or physiologic angulation (p = 0.014), whereas flexion force was unaffected (p = 0.468). The anatomical reduction had no influence on shoulder strength. CONCLUSIONS: Proximal humerus fractures may cause a significant reduction in shoulder function, both reported by patients and objectified by shoulder strength testing. Varus head angulation demonstrated the greatest loss of shoulder strength and should be avoided to ensure proper functioning. Further, strength testing seems a valuable outcome parameter for a thorough shoulder examination with easy obtainability.

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.

The lesser trochanter profile is an accurate and reliable measure of femoral rotation for intramedullary nailing.

INTRODUCTION: The lesser trochanter profile (LTP) method is an intraoperative fluoroscopic technique that can assess the femoral version and limit malrotation. The purpose of this study was to directly assess the accuracy and reliability of the LTP method, as well as determine the incidence of malrotation produced by this technique. METHODS: Three groups of observers (fellowship-trained orthopedic surgeons, orthopedic residents, and medical students) utilized the LTP method to replicate pre-imaged rotation angles on a cadaveric femur bone. Recorded outcomes include rotational error and number of attempts. Accuracy and interobserver reliability were assessed by rotational error and the interclass correlation coefficient (ICC), respectively. RESULTS: Accuracy was within 3° for all three groups. ICC between each group was greater than 0.99. There was no statistical difference between the accuracy of fellowship-trained surgeons, orthopedic residents, and medical students. Medical students on average required more attempts to obtain their final image compared to fellowship-trained surgeons. There was no statistical difference in the number of attempts between residents and fellowship-trained surgeons. CONCLUSION: None of the LTP measurements were greater than 15°, the clinical threshold for malrotation. The average error of the observers was less than 3°, demonstrating that the LTP is an effective method of assessing the femoral version. There was no statistically significant difference between the observers, indicating that this technique is reliable and easy to use. Ultimately, the LTP method is easily reproducible for surgeons to avoid femoral malrotation.

Non-Vascularized Fibular Cortical Strut Graft with Intramedullary Nailing for Fibrous Dysplasia of the Proximal Radius - A Case Report.

Introduction: Fibrous dysplasia (FD) is a skeletal developmental abnormality commonly affecting the ribs, femur, tibia, skull, pelvis, spine, and shoulder. FD of the proximal radius is extremely rare and very few cases have been reported. In addition, monostotic lesions of FD in the upper extremity go unnoticed as they are usually asymptomatic. Symptomatic lesions warrant surgical intervention. Here, we present a rare case of FD of the proximal radius treated with curettage and non-vascularized fibular cortical strut graft with intramedullary elastic nailing. We believe that this is the first report in the literature wherein this treatment modality has been undertaken. Case Report: A 27-year-old woman presented with excruciating pain and swelling in her right elbow for 4 weeks, with no inciting event or trauma leading to the pain. Plain radiographs revealed a well-circumscribed radiolucent lesion in the proximal radius with cortical thinning at the metaphysis and a rim of epiphyseal bone. Clinically, the patient had restricted supination (50°) and limited elbow range of motion (ROM) (20-130°), mostly because of the pain but had full pronation. With these radiographic and clinical features, FD and giant cell tumor were kept as differential diagnoses and surgical treatment was planned. The lesion was excised leaving the normal epiphysis of the radius intact and samples were sent for histopathological examination. A non-vascularized fibular cortical strut graft was harvested from the same side and was fluted into the radial shaft. Final stabilization was done using a 2.5 mm intramedullary elastic nail. The arm was immobilized in an above-elbow slab. Histopathology confirmed our diagnosis of FD. The slab was removed after 6 weeks, and a gentle ROM was started in the form of active-assisted ROM. At the end of 1 year, complete union and almost full ROM were achieved and the patient was completely pain-free. Conclusion: Non-vascularized fibular strut grafting with intramedullary nailing provides a comparatively quicker, cost-effective way of treating this lesion with a minimum insult of the bony cortex and quicker rehabilitation.

Compartment Syndrome Following Intramedullary Nailing of the Tibia: A Case Report.

Introduction: Compartment syndrome as a complication during intramedullary nailing of closed tibia fractures was first documented as early as 1980. Case Report: We report a case of a 19-year-old young man victim of a road accident (motorcycle accident) causing an uncomplicated closed fracture of 2 bones of the left leg. The patient underwent centromedullary nailing of the tibia. The evolution was marked by the early onset of an acute and serious compartment syndrome. Conclusion: The first symptom of compartment syndrome is pain regardless of the severity of the trauma. The diagnosis is clinical and is generally confirmed by measuring the pressure in the muscle compartment. The treatment is fasciotomy.

Modified Use of Humerus Nail for Management of Tibia Diaphyseal Fracture - Rare Case Report.

Introduction: There have been very few cases of intramedullary (IM) nailing for tibia shaft fracture using a humerus nail. We present to you a unique case of humerus nail used in tibia shaft fracture in a short-stature patient. Case Report: A 26-year-old female, was brought to our emergency room, she sustained trauma to her left leg while she was walking on the road hit by an automobile (pedestrian injury) with complaints of pain and swelling in her left leg. She has a family history of short stature. X-ray suggested of left tibia diaphyseal fracture with a left calcaneum fracture (undisplaced). Preoperatively, tibia length came out to be 22 cm. The shortest tibia nail available is 26 cm. Hence, the plan was to do IM humerus nailing. Closed reduction with internal fixation was done with a similar method as in tibia nailing. Titanium nail of size 8 mm × 22 cm was used. In the humerus nail, the bend is lateral, which was kept posteriorly as Herzog bends in the tibia nail. Postoperatively, patient was given below knee slab with nil weight bearing for 6 weeks. Conclusion: Use of IM humerus nailing in tibia diaphyseal fracture fixation is possible. It provides rotational stability, leg length control, early mobilization and is also available in smaller sizes. Tibial fracture fixation with humeral nails in patients with short limb lengths is one of the possible options with satisfactory outcomes.

Treatment Outcomes of Dynamic Hip Screws Versus Short Intramedullary Nails for Extra-capsular Fragility Hip Fractures and Their Coding Audit.

Introduction In the UK, hip fractures are a common reason for presentations to the emergency departments, which places significant pressure on NHS hospitals, appropriate choice of an implant to treat the hip fracture is one among many other factors that affect patients' outcomes. This audit aims to identify and compare the outcome difference between the dynamic hip screws (DHS) and short cephalomedullary nails in the treatment of extracapsular hip fractures. Methods In a retrospective study of 52 patients admitted as a result of hip fractures in one NHS trust, data collection was done from the patients' records using the trust's online system, we studied different variables to compare the outcome difference between DHS and short intramedullary (IM) nails, two senior authors interpreted the patients' X-rays and verified the coding and classification of the neck of femur fractures. Results This retrospective study examined 52 extracapsular hip fracture cases, including 37 females and 15 males. Forty-six (88%) of the included patients were ASA 3 and 4 (American Society of Anesthesiologists), and the average days to discharge from therapies were 8.4 (SD-+ 4) days compared to 11 (SD-+ 5.2) days for short IM nails and DHS, respectively (P= 0.03), the 30-day mortality rate for short nails was 7% (n= 4/52) patients and 6% (n= 3/52) for DHS (P =0.69). The mean operating times for the different implants were 58.11 (SD-+ 15.1) minutes for DHS and 58.03 (SD-+ 23.2) minutes for the short nail (P =0.98). Compliance with the national guidelines for providing an appropriate operation to treat hip fractures initially went from 63% (n=33/52) initially to 73% (n=38/52). This means that more patients who are appropriate for nailing are being treated with IM nails. Conclusion Short IM nails are associated with faster hospital discharge; this fact may be reflecting the lower postoperative pain as a result of avoiding soft tissue dissection associated with extramedullary devices. keeping in mind that IM devices have mechanical advantages over sliding hip screws; hence, they are more commonly used for more complex fracture patterns, leading to nearly similar outcomes when compared to extramedullary devices, this can be a source of bias in retrospective studies, larger randomized trials may lead to different outcomes.

Closed Reduction Nailing or Open Reduction Plating in Unstable Paediatric Forearm Fractures: A Case of Paediatric Forearm Fracture Implant Failure.

A significant amount of all paediatric fractures are forearm fractures involving the radius, ulnar shaft, or both. As surgical stabilisation lowers the likelihood of re-displacement, surgical intervention is currently recommended over conservative treatment of such fractures involving significant displacement and angulation. Open reduction and plating can better anatomically repair the majority of fractures. Bracing is necessary for the first six to eight weeks after nailing since nailing does not give a rigid fixation. External bracing is generally not necessary for plating. In our facility, paediatric diaphyseal forearm fractures are typically treated using titanium elastic nail system (TENS) nailing. However, there are occasional instances where the primary fracture site refractures after surgery, particularly in diaphyseal forearm fractures involving both bones. Our patient was a 12-year-old boy who had come to our facility with a left forearm radius shaft fracture and ulna shaft plastic deformation. The radius shaft fracture was fixed with TENS nailing, and the ulna shaft plastic deformation was corrected by the three-point bending method. Three months later, the patient came back with a refracture of the radius shaft. TENS nail removal, open reduction, and internal fixation of the radius shaft refracture were done with a plate and screws. Anatomic reduction of forearm fractures, open reduction, and the use of plate fixation enable a more thorough correction of malrotation and restoration of the radial bow, allowing for an early range of motion. Since the TENS nail is not a locking device, there is always some amount of mobility at the fracture site, causing loss of reduction, chances of implant failure, and non-union. So primary plating, especially in cases of forearm fractures, appears to be a better option compared to primary TENS nailing in juvenile patients.

Double Segmental Femoral Fracture: A Rare Injury Following High-Energy Trauma.

Femoral fractures are indubitably common injuries that can occur either from high-energy trauma in young patients or due to fragility in the geriatric population. Femoral fractures affecting two or more regions of the femur are exceedingly infrequent injuries, ordinarily caused by high-energy trauma and are considered segmental femoral fractures. We present a rare case of a 33-year-old male patient presented to our Emergency Department with multiple femoral fractures at the subtrochanteric, diaphyseal and supracondylar femoral regions, a condition regarded as double segmental femoral fracture. After assiduous consideration of treatment options, intramedullary nailing was employed for osteosynthesis. Fracture reduction was laborious, as an entirely separated femoral fragment was present between the fracture lines. The reaming process required paramount attentiveness as the middle femoral fragment was prone to rotational displacement by the reamer. Finally, the intramedullary nail was successfully placed, and the patient was discharged without complications after 11 days of hospitalization. Currently, the patient is capable of full weight-bearing without crutches. This paper underlines the challenges that double-segmental femoral fractures' treatment can bring on to the orthopedic surgeon.

Forward-striking technique in simple femoral shaft fractures: a comparative cohort study.

BACKGROUND: A persistent fracture gap following femoral nailing increases the risk of delayed and nonunion development. A forward-striking technique for reducing the gap in femoral nailing has been described, but its efficacy and therapeutic consequences have not been investigated in comparative studies. We provide the results of a comparative study that investigated the forward-striking technique's efficacy in terms of remaining fracture gaps and surgical outcomes. METHODS: Between 2017 and 2022, a retrospective cohort study was undertaken on 193 skeletal mature patients obtaining reamed femoral nailing for closed femoral shaft fractures. Comparisons of residual fracture gaps, timing to union, complications and re-operation rates were made between 80 patients (41.45%) undergoing femoral nailing with the forward striking procedure and 113 patients (58.55%) undergoing traditional nailing, accompanied by minimal 1-year follow-ups. In addition, the potential difference between fracture gaps before and after applying the forward striking procedure was compared. RESULTS: Both groups had similar age, sex, presence of diabetes, smoking status, body mass index and time to surgery. However, the forward-striking group demonstrated significantly lower rates of postoperative complications, including delayed, nonunion, and the need for re-operation. Conversely, no significant differences were found in time to union (p = 0.222). The forward-striking procedure can significantly reduce residual fracture gaps from 3.99 to 1.66 mm (p < 0.001). No major complications in the forward-striking group including nonunion were observed. CONCLUSION: This study suggests that the forward-striking technique effectively reduces residual fracture gap during femoral nailing. The technique not only could be easily performed but is also reproducible. In addition, it can lower the risk of delayed union, nonunion and obviates the necessity for re-operation. LEVEL OF EVIDENCE: Level III, retrospective cohort study.

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.

The efficacy of suprapatellar, parapatellar and infrapatellar intramedullary nailing in the treatment of tibial fractures: a systematic review and meta-analysis.

BACKGROUND: Tibial fractures are common and challenging orthopedic injuries that are commonly treated with intramedullary nailing techniques via suprapatellar (SP), parapatellar (PP), and infrapatellar (IP) approaches. This study aimed to provide a comprehensive comparative analysis of the efficacy of different treatment approaches based on clinical outcomes. METHODS: We conducted a detailed search in PubMed, Cochrane Library, Embase, and Web of Science for clinical studies comparing suprapatellar, parapatellar, and infrapatellar approaches in intramedullary nailing of tibial fractures. Inclusion criteria included randomized controlled trials and retrospective cohort studies involving patients aged 18 and older, comparing outcomes of these surgical techniques. Exclusion criteria included studies with insufficient data, non-English publications, and those focusing on non-tibial fractures. RESULTS: A total of 15 studies involving 1396 patients were included in meta-analysis. Pooled results indicated that, compared to IP nailing, the SP approach significantly reduced fluoroscopy time (MD = - 35.63, 95% CI - 39.37 to - 31.89, p < 0.001), operative time (MD = - 10.72, 95% CI - 17.30 to - 4.15, p = 0.001), pain scores (SMD = - 1.49, 95% CI - 2.36 to - 0.62, p < 0.001), and improved Lysholm scores (MD = 5.74, 95% CI 3.29 to 8.19, p < 0.001) and malalignment rate (RR = 0.24, 95% CI 0.08 to 0.68, p = 0.008). Quality of life assessments also indicated higher physical component scores for the SP group (MD = 6.68, 95% CI 5.19 to 8.17, p < 0.001). CONCLUSION: The SP approach provides significant intraoperative and postoperative benefits, reducing surgery time and improving patient outcomes in pain management and knee joint function. These findings support the SP approach as a preferred option for surgical treatment of tibial fractures.

Trends in Epidemiology and Treatment of Humerus Fractures in the United States, 2017-2022.

Background Fractures of the humerus are one of the more common fractures in the United States and a cause of fragility fractures in the elderly population. This study aims to understand recent trends in the demographic factors correlated with humeral shaft fractures (HSF) and humeral shaft fracture nonunion (HSFN) following open reduction internal fixation (ORIF) and intramedullary nailing (IMN). Methods The TriNetX database was used to query using International Classification of Diseases-10 (ICD10) diagnosis codes for patients who sustained HSF between 2017 and 2022. Patients were then organized into cohorts based on Current Procedural Terminology (CPT) codes 24515 and 24516 for ORIF and IMN of HSFs, respectively. Subsequent nonunion after operative management was queried. Descriptive and comparative analysis was performed to examine the differences observed between patients based on age, sex, ethnicity, race, and smoking status as well as surgical management across the six-year study period. Results The incidence of HSF increased from 7,108 in 2017 to 8,450 in 2022. The rate of HSF ORIF increased from 12% to 17% while the nonunion rate following ORIF decreased from 4% to 3%. The rate of HSF IMN increased from 4% to 6% and the rate of nonunion following IMN increased from 2% to 4%. The overall rate of HSFN surgery was 1.7% with slight decreasing trend over the past year. Conclusion It is speculated that improved care and surgical indications resulted in a lower rate of nonunion despite an increase in the overall rate of HSF and its operative managements.

A Randomized Controlled Study on the Efficacy of Different Approaches of Intramedullary Nailing with Blocking Screws for Proximal Tibial Fractures

SUMMARY: The objective of this study was to compare and analyze the clinical efficacy of different approaches of intramedullary nailing with blocking screws for proximal tibial fractures. One hundred cases of proximal tibial fractures treated in the orthopedic department from April 2021 to September 2023 were included in the study and divided into control and treatment groups using a random number table. A control group (n=50) treated with infrapatellar intramedullary nailing with blocking screws, and a treatment group (n=50) treated with suprapatellar intramedullary nailing with blocking screws. We observed the excellent and good rates in both groups, compared various perioperative indicators, changes in joint range of motion (ROM), Visual Analog Scale (VAS) pain scores, Lysholm knee joint function scores, changes in inflammatory factors, and various bone markers before and after treatment, and analyzed postoperative complications. There were no significant differences in baseline data such as age, sex, body mass index, fracture site, concomitant fibular fractures, time from fracture to surgery, injury mechanism, and AO/OTA fracture classification between the two groups (P>0.05). The excellent and good rate in the treatment group after treatment was 90.00 % (45/50), significantly higher than 72.00 % (36/50) in the control group (P0.05). However, the treatment group had shorter surgical times and fewer fluoroscopy times than the control group (P<0.05). After treatment, both groups showed increased ROM and Lysholm scores, as well as decreased VAS scores. Moreover, compared to the control group, the treatment group had higher ROM and Lysholm scores and lower VAS scores (P<0.05). Inflammatory factors including interleukin-1β (IL-1β), C-reactive protein (CRP), tumor necrosis factor-α (TNF-α), osteocalcin (BGP), and calcitonin (CT) increased in both groups after treatment, while total n- terminal propeptide of type I procollagen (Total-PINP) and b-C-terminal telopeptide of type I collagen (β-CTX) decreased. Compared to the control group, the treatment group exhibited greater increases in inflammatory factors and lower levels of Total-PINP and β-CTX, but higher BGP and CT levels (P<0.05). The incidence of postoperative complications was 8.00 % (4/50) in the treatment group and 24.00 % (12/50) in the control group, with statistically significant differences (P=4.762, X2=0.029). In the treatment of proximal tibial fractures, intramedullary nailing with blocking screws using the suprapatellar approach achieves significant clinical efficacy. It reduces surgical time, minimizes radiation exposure to healthcare workers and patients, improves knee joint range of motion and function, decreases postoperative pain and complication rates, suppresses inflammatory reactions, and promotes the improvement of bone markers related to fracture healing.

El objetivo de este estudio fue comparar y analizar la eficacia clínica de diferentes abordajes de clavo intramedular con tornillos de bloqueo para las fracturas de tibia proximal. Se incluyeron en el estudio 100 casos de fracturas de tibia proximal tratados en el departamento de ortopedia desde abril de 2021 hasta septiembre de 2023 y se dividieron en grupos de control y de tratamiento mediante una tabla de números aleatorios. Un grupo control (n=50) tratado con clavo intramedular infrapatelar con tornillos de bloqueo, y un grupo tratamiento (n=50) tratado con clavo intramedular suprapatelar con tornillos de bloqueo. Observamos excelentes y buenas tasas en ambos grupos, comparamos varios indicadores perioperatorios, cambios en el rango de movimiento articular (ROM), puntuaciones de dolor en la escala visual analógica (EVA), puntuaciones de función Lysholm de la articulación de la rodilla , cambios en factores inflamatorios y varios marcadores óseos, antes y después del tratamiento, y se analizaron las complicaciones postoperatorias. No hubo diferencias significativas en los datos iniciales como edad, sexo, índice de masa corporal, sitio de fractura, fracturas de fíbula concomitantes, tiempo desde la fractura hasta la cirugía, mecanismo de lesión y clasificación de fractura AO/OTA entre los dos grupos (P>0,05). La tasa de excelente y buena en el grupo con tratamiento después del tratamiento fue del 90,00 % (45/50), significativamente mayor que el 72,00 % (36/50) en el grupo control (P0,05). Sin embargo, el grupo con tratamiento tuvo tiempos quirúrgicos más cortos y menos tiempos de fluoroscopía que el grupo control (P <0,05). Después del tratamiento, ambos grupos mostraron un aumento de las puntuaciones de ROM y Lysholm, así como una disminución de las puntuaciones de VAS. Además, en comparación con el grupo control, el grupo con tratamiento tuvo puntuaciones ROM y Lysholm más altas y puntuaciones EVA más bajas (P <0,05). Los factores inflamatorios que incluyen interleucina-1β (IL-1β), proteína C reactiva (CRP), factor de necrosis tumoral-α (TNF-α), osteocalcina (BGP) y calcitonina (CT) aumentaron en ambos grupos después del tratamiento, mientras que el total disminuyó el propéptido n-terminal del procolágeno tipo I (Total-PINP) y el telopéptido β-C-terminal del colágeno tipo I (β-CTX). En comparación con el grupo control, el grupo con tratamiento mostró mayores aumentos en los factores inflamatorios y niveles más bajos de Total-PINP y β-CTX, pero niveles más altos de BGP y CT (P <0,05). La incidencia de complicaciones postoperatorias fue del 8 % (4/50) en el grupo de tratamiento y del 24 % (12/50) en el grupo control, con diferencias estadísticamente significativas (P=4,762, X2=0,029). En el tratamiento de las fracturas de tibia proximal, el clavo intramedular con tornillos de bloqueo mediante el abordaje suprapatelar logra una eficacia clínica significativa. Reduce el tiempo quirúrgico, minimiza la exposición a la radiación de los trabajadores de la salud y los pacientes, mejora el rango de movimiento y la función de la articulación de la rodilla, disminuye el dolor postoperatorio y las tasas de complicaciones, suprime las reacciones inflamatorias y promueve la mejora de los marcadores óseos relacionados con la curación de las fracturas.

Predictive value of tip-apex distance and calcar-referenced tip-apex distance for cut-out in 398 femoral intertrochanteric fractures treated in a private practice with dynamic intramedullary nailing.

Introduction: Cut-out, a biomechanical complication, is one of the most common causes of internal fixation failure of trochanteric hip fractures. The tip-apex distance (TAD) and the calcar-referenced tip-apex distance (CalTAD) have been suggested as the radiographic parameters that most predict the risk of cut-out. The purpose of this study was to check whether these two factors could predict implant cut-out in a series 398 of intertrochanteric hip fractures, treated by dynamic intramedullary nailing with the Trigen Intertan short nail. Methods: We reviewed 398 consecutive intertrochanteric fractures included in a prospective study and treated in a single private hospital by the same surgeon. The radiographic parameters were obtained from anteroposterior (AP) and axial hip plain radiographs before surgery, immediately postoperatively, and every 3 weeks after surgery until 3 months postoperatively, and every month until the 6-month follow-up. The concept of medial cortex support (MCS) was also analyzed as a criterion for evaluating the quality of fracture reduction. Results: The overall cut-out rate was 2.3% (9/398). The significant parameters in the univariate analysis were AO fracture type, quality of fracture reduction (p = 0.02), TAD (p < 0.001), CalTAD (p = 0.001), and quality of reduction. No statistically significant relationships were observed between the occurrence of cut-out and sex, age, fracture side, and American Society of Anesthesiologists type. Varus collapse and cut-out were only found in cases of negative MCS (22.2% and 77.8%, respectively). Multivariate analysis showed that only TAD showed an independent significant relationship to cut-out (p < 0.001). In this study, CalTAD has no predictive value in the multivariable analysis. Conclusions: Our findings differed from those in previous reported studies suggesting that CalTAD is the best predictor of cut-out. According to our data, careful optimal reduction ensuring stable fixation with TAD >25 mm reduced the occurrence of cut-out after dynamic intramedullary nailing of intertrochanteric fractures.
