Impact of buried versus exposed flexible intramedullary nails osteosynthesis on pediatric forearm fractures

To determine the risk of re-fracture in patients with a nail buried directly into the amr or left exposed as a treatment for forearm fractures, and to investigate postoperative complications. The study included 113 pediatric patients with a forearm fracture of both diaphyses. Two groups were formed according to whether the nail was buried (Group B, n: 53) in the same arm or left exposed (Group E, n: 60). Data on the number of open reductions, the time to nail removal, the anesthesia type used for its removal, the number of re-fractures, skin infection, and nail entry site irritation were analyzed. The mean union times between the groups were not significantly different (P = 0.371). The mean time of nail removal in group B (16.02 ± 1.29 weeks) was significantly longer than that of group E (6.65 ± 0.95 weeks) (P < 0.001). Open reduction rates were similar between groups (P = 0.401). The general anesthesia rate for nail removal in group B (77.4%) was significantly higher than group E (11.7%) (P < 0.001). The re-fracture rate was higher in patients who underwent open reduction in both groups (P < 0.001). The results of this study demonstrated that, despite the increased infection rate, leaving the nail exposed did not increase the re-fracture rate, which was associated with open reduction.

Implants removal in children: results of a survey among Italian orthopaedic surgeons.

In the treatment of paediatric limb disorders, the use of metal implants has been increasing over the last decades. Recent studies have addressed the decision of orthopaedic surgeons regarding the removal of implants after the treatment of fracture, and there is a growing consensus within the scientific community supporting the choice of not removing implants in children. This survey aimed to investigate the rationale behind the Italian orthopaedic community's decision regarding metal implant removal in paediatric patients. An electronic questionnaire was sent to all members of the Italian Paediatric Orthopaedic and Traumatology Society, Italian Orthopaedic and Traumatology Society, Italian Club of Osteosynthesis, and South Italy Society of Orthopaedic and Traumatology. The survey comprised 34 questions about hardware removal after the treatment of long bone fractures, epiphyseal growth plate injuries, slipped capital femoral epiphysis (SCFE), and flat foot. Of the 3500 orthopaedic surgeons who received the questionnaire, 5.5% responded. The leading indications for implant removal were the patient's intolerance, pain, ROM limitations, and hardware breakage. Removal of elastic nails for long bone fractures, cannulated screws for growth plate injuries, and SCFE and screws for arthroereisis for flat foot correction were analysed in detail. The consensus among Italian Orthopaedic Surgeons is to remove elastic nails and cannulated screws in cases of pain, intolerance, or breakage and to reduce further risks during patient growth. An increasing number of physicians, however, are endorsing and advocating the growing trend in the literature of not routinely removing the hardware.

Factors which can influence elastic stable intramedullary nailing removal in healed bone cysts in children

Elastic stable intramedullary nailing (ESIN) internal fixation is used clinically to treat pathological fractures of bone cysts in children. However, one of the most important complications was removal difficulty. In this study, we aim to analyse the factors which can influence ESIN removal in healed bone cysts in children. From April 2014 to November 2020, the clinical data of 49 children who underwent elastic stable intramedullary nail removal for pathological fractures of the bone cysts in our hospital were retrospectively analysed. The following data, including age, sex, pathological fracture site, with bone graft, number of ESINs, ESIN indwelling time, and extraosseous length of ESIN were collected, and univariate analysis and logistic regression analysis was performed. The frequency of difficulty in ESIN extraction was 44.90% (22/49). The univariate logistic regression analysis showed that age,ESIN indwelling time,with bone garft and extraosseous length of ESIN may be correlated with the difficulty in removing ESIN (P < 0.05), while sex, pathological fracture site, number of ESIN may not be correlated with the difficulty in removing ESIN (P > 0.05).The multivariate logistic regression analysis showed that the ESIN indwelling time was the independent influencing factor for difficulty in removing ESIN (P < 0.05). The factors influencing the ESIN removal in healed bone cysts in children include over 11.79 years old, the long indwelling time of the ESIN(over 10.5 months),with bone graft and short extraosseous length of ESIN(≤ 0.405 cm). These factors influencing ESIN removal in healed bone cysts in children should be considered.

Comparing the Outcomes of Titanium and Stainless Steel Flexible Nails in Repairing Pediatric Long Bone Fractures.

Traditionally, pediatric femoral fracture treatment favored conservative methods, relying on casting and the inherent bone remodeling ability in immature bones. Surgical intervention was deferred until age 6, as nonoperative approaches often resulted in complications. Titanium elastic nailing (TENS) emerged as an effective treatment for diaphyseal femoral fractures in ages 6 to 16. However, the choice between TENS and stainless steel elastic nailing (SSENS) remains debated due to inconsistent findings. This study aimed to evaluate the effectiveness of both nailing systems in pediatric long bone fractures. A retrospective chart review at William Beaumont Hospital Royal Oak included 83 patients aged 6 to 16 treated with TENS or SSENS between January 2011 and January 2021. Data collected encompassed nail related issues, time to fracture union, full weight bearing, and nail removal. In the TENS group (n=29), the average age was 8.8±2.4 years, and the average BMI was 17.2±3.4. The SSENS group (n=54) had an average age of 9.3±2.7 and an average BMI of 19.7±8.4. Time to fracture union for TENS was 93.8±60.5 days, while SSENS was 82.2±40.0 days. This study found no statistically significant differences in nail-related complications, time to fracture union, full weight bearing, or nail removal between TENS and SSENS in pediatric long bone fractures. The choice between these systems should be based on individual circumstances. Limitations include a small sample size and the study's retrospective nature.

Elastic stable intramedullary nail combined with Kirschner wire (E-K) technique for treating pediatric distal tibial diaphyseal metaphyseal junction (DTDMJ) fractures.

Elastic stable intramedullary nail (ESIN) is a commonly used method for treating diaphyseal fractures of the tibia, but its application in Distal Tibial Diaphyseal Metaphyseal Junction (DTDMJ) fractures has been a subject of controversy. This study aims to evaluate the clinical efficacy of the Elastic stable intramedullary nail-Kirschner wire (E-K) technique in treating pediatric DTDMJ fractures, providing better clinical decision-making for clinicians in diagnosing and treating such fractures. We conducted a retrospective analysis of patients aged 3-9 years who received treatment at our hospital from January 2019-January 2021 for distal tibial diaphyseal metaphyseal junction (DTDMJ) fractures. Based on their surgical procedures, they were categorized into the Elastic Stable Intramedullary Nail-Kirschner wire group (E-K) and the ESIN group. Demographic data, surgical duration, clinical outcomes, complications, and imaging data were recorded. The study included a total of 57 patients, with 24 cases in the E-K group and 33 cases in the ESIN group. There were 30 males and 27 females. The average age was (6.25 ± 1.59) years in the E-K group and (6.27 ± 1.48) years in the ESIN group. There were no significant differences between the two groups in terms of gender, age, weight, time from injury to surgery, follow-up time, side of injury, associated injuries, nail site infection, deep infection, and nail removal time (P > 0.05). Neither group experienced nonunion or refracture. The E-K group exhibited significantly lower coronal and sagittal plane angular values at the final follow-up compared to the ESIN group (P < 0.001). In the E-K group, the final follow-up coronal plane angle was 2.67 (1.09)°, while in the ESIN group, it was 6.55 (2.05)°. The final follow-up sagittal plane angle was 3.12 (1.54)° in the E-K group and 7.58 (1.48)° in the ESIN group. Both groups showed good alignment in the initial postoperative x-rays, with no statistically significant differences. However, during clinical healing, the ESIN group exhibited significant displacement, whereas the E-K group had minimal displacement, demonstrating a significant statistical difference (P < 0.001). There was a statistically significant difference in the AOFAS joint function assessment between the two groups (P = 0.027). The E-K technique is a viable option for treating DTDMJ fractures in pediatric patients, with well-established clinical efficacy. Its advantages include a straightforward surgical procedure, safety, and a low incidence of severe complications.

Intramedullary Nailing with an Absorbable Antibiotic Carrier (INaac): A Simple Technique Using Standard Implants

Introduction: Intramedullary nailing has revolutionized the treatment of long bone fractures and non-unions. However, there is rightly concern about the use of nails when there is established infection or when the risk of subsequent infection is high. Recently, this concern has been partly addressed by the introduction of intramedullary nails combined with an antibacterial coating. Various methods have been reported with some success but also with some drawbacks. Methods: This paper reports a simple technique for coating an intramedullary nail with an absorbable antibiotic carrier. The carrier is injected directly into the reamed medullary canal, coating the nail during nail passage and delivering high levels of antibiotics at the nail-bone interface. Results: This technique was found to be easy to apply. It allowed use of standard fracture implants without the need for downsizing of the nail diameter. There is no need for nail removal or exchange after initial treatment of the infection. Conclusion: This simple technique combines the benefits of a bioabsorbable antibiotic carrier with standard fracture nails to prevent or treat long bone infections. It avoids the problems of PMMA coated nails or the need for specialist implants.

Outpatient limb lengthening using magnetic intramedullary nails: A single Institution's experience

IntroductionThe advantages of outpatient surgery have been shown in other orthopedic subspecialities to be a means of driving down costs and reducing the average length of hospital stay. However, there is a scarcity of literature examining the utility of a specific, hospital-based facility performing such procedures for limb lengthening. Considering this, we aimed to investigate surgical factors, patient characteristics, and the incidence of outpatient postoperative complications for patients undergoing surgery and subsequent distraction osteogenesis utilizing the Precice® nail, a state-of-the-art magnetic intramedullary nail (MILN). MethodsWe performed a retrospective review of medical records pertaining to outpatient limb lengthening procedures occurring between January 2012 and September 2023 at a single institution, as performed by three surgeons. Variables of interest included baseline demographics, type of anesthesia, operative bone, laterality, preoperative diagnosis, osteotomy level, procedure performed, prosthesis, point of entry, nail diameter/length, goal length, goal achieved, postoperative complications, and elective nail removal. ResultsThe cohort comprised 20 limbs, with an average age at index surgery of 24.8 (SD 7.96). There were no complications related to the outpatient nature of the procedure. Five of the 20 limbs had postoperative complications, including deep vein thrombosis (DVT), screw backout, and nail breakage. ConclusionOur initial investigation of outpatient limb lengthening at a specific, hospital-based facility demonstrated favorable postoperative outcomes for those patients undergoing limb lengthening procedures with an MILN. The field would certainly benefit from future research assessing outcomes of pediatric surgeries in the outpatient setting on a larger scale, as well as across hospital systems, the country, and globally. With the proven advances and benefits of MILNs, prioritizing examination of their efficacy in an outpatient population is imperative. Furthermore, the success of outpatient procedures in other orthopedic subspecialities, such as total joint arthroplasty, is a logical, driving precedent for this rationale.

Utilizing Community Procedure Clinics to Enhance Resident Procedural Education.

Procedure training in family medicine residency is important for future full-spectrum practice. Some residency programs have cited difficulty providing adequate procedure education. Residency collaboration with nonfaculty attending physicians working at community nonresidency clinics may help programs increase resident exposure to procedures. We assessed the feasibility of such an educational model by establishing recurring procedure clinics in a nonresidency family medicine site supervised by nonfaculty physicians. Twice monthly, half-day procedure clinics were conducted at a community site, where family medicine residents were supervised by nonfaculty community family physicians. After participation, we surveyed residents about their perceptions of the clinics. Using retrospective chart review, we determined quantity and type of procedures performed. Fifteen residents participated in 21 procedure clinics, featuring 18 procedure types and 268 procedures. Skin lesion excision, nail removal, punch and shave procedures, joint injection, newborn circumcision, and implantable contraception management were most consistently performed. Residents rated clinics highly and were satisfied with procedure number and variety, opportunity to learn new procedures and techniques, and feedback received. Over 80% of residents noted experiences in procedures that were less commonly encountered in their residency. Procedure clinics at a nonresidency site hosted by nonfaculty attending physicians provided additional training in a variety of primary care procedures. The clinics were favorable to residents and may help programs address training gaps.

Removal of a Bent Intramedullary Nail in Lower Extremity: Review of Removal Techniques

Removal of a Bent Intramedullary Nail in Lower Extremity: Review of Removal Techniques

Healthcare Wearable Sensors Adhesion to Human Fingernails and Toenails.

A novel adhesion method of a sensor to a fingernail is described. Wearable sensors can provide health insights to humans for a wide variety of benefits, such as continuous wellness monitoring and disease monitoring throughout a patient's daily life. While there are many locations to place these wearable sensors on the body, we will focus on the fingertip, one significant way that people interact with the world. Like artificial fingernails used for aesthetics, wearable healthcare sensors can be attached to the fingernail for short or long time periods with minimal irritation and disruption to daily life. In this study the structure and methods of healthcare sensors' attachment and removal have been explored to support (1) the sensor functional requirements, (2) biological and environmentally compatible solutions and (3) ease of attachment and removal for short- and long-term user applications. Initial fingernail sensors were attached using a thin adhesive layer of commonly available cosmetic nail glue. While this approach allowed for easy application and strong adhesion to the nail, the removal could expose the fingernail and finger to a commercially available cosmetic nail removal (acetone-based chemical) for extended times measured in minutes. Therefore, a novel structure and method were developed for rapid healthcare sensor attachment and removal in seconds, which supported both the sensor functional objectives and the biologically and environmentally safe use objectives.

Late Removal of Brain-Penetrating Nails Adherent to Intracranial Arteries: A Case Report

BACKGROUND AND IMPORTANCE: Pneumatic nail guns are a rare cause of penetrating brain injury, and subsequent nail removal in the acute setting is well reported. However, reports of late removal or removal of nails adjacent to intracranial vessels are rare. In the delayed setting, scar formation around the nails and surrounding brain structures may complicate surgical removal. Here, we report a case of late removal of brain-penetrating nails adherent to the middle cerebral artery branches. CLINICAL PRESENTATION: A 70-year-old left-handed male presented with mild aphasia, vertigo, and facial nerve palsy. Imaging studies demonstrated two nails fired 2 months before in the right temporal lobe adjacent to the middle cerebral artery branches. The nails were surgically removed through a modified pterional approach after meticulous dissection of scar tissue adherent to the nails. Before removal, proximal vessel control was achieved. CONCLUSION: Brain-penetrating nail removal weeks after the original incident may be complicated by extensive scarring. This can be dealt with a generous craniotomy, proximal vessel control through microsurgical or endovascular means, and careful dissection of scar tissue around the nails.

Nail-extraction device mismatch: an issue in developing countries intramedullary nail removal practice.

Intramedullary nail is the gold standard in the management of long bone diaphyseal fractures of tibia and femur. The jig of these nails has corresponding extraction device whose pitch for nail coupling come in various sizes. This unlike plate and screws may be difficult to predict preoperatively and may pose a problem during removal. Difficulties in removal may arise due to the proliferation of nail brands especially in developing countries. The study aims to identify the incidence of extraction device mismatch among orthopaedic surgeons in Nigeria as well as the indications and complications associated with intramedullary nail removal. A two-page questionnaire was administered to 87 orthopaedic surgeons attending the Annual General Meeting of the Nigerian Medical Association. The attitudes of the participants towards intramedullary nail were assessed. All participants agree to asymptomatic removal. Patients wish was the leading indication for asymptomatic removal among the participants. Sixty-one percent of the surgeons have had the need to remove a nail different from the brand in the hospital their practice. The commonest indication for symptomatic removal was infections. Forty-seven percent of the participant encountered nail extraction-device mismatch. The incidence of extraction device mismatch may portend a public health issue. There may be need for patient who had intra medullary nail insertion to be told their brand. We advocate for standardization of extraction device pitch for intramedullary nail.

Infection after intramedullary nailing of femoral and tibial diaphyseal fractures

PurposeManagement of fracture-related infection (FRI) after intramedullary fixation (IF) is a challenge. The aim of the present study is to describe a series of 26 patients with FRI after IF and to evaluate factors possibly related to the outcome. MethodsBaseline variables were obtained at the time of IF: age, sex, body mass index, affected bone, open fracture, substance abuse, use of an external fixator, type of nail, reaming, soft-tissue reconstruction and surveillance culture result. After diagnosis of the infection, information was obtained about the time interval between IF and diagnosis and classification according to both the Willeneger and Roth and Makridis systems. Treatment modalities were grouped and analysed according to: use of antimicrobials, surgical debridement, nail removal or retention and spacer use. Cultures of bone or deep soft tissues were performed. Patients were followed up for 12 months, and outcomes (remission, relapse, death and loss of follow-up) were evaluated, as well as fracture consolidation. ResultsRemission was observed in 42.3% of patients. There was no significant association between any baseline variable and outcome. There was a significant association between Makridis stage 2 classification and recurrence or death. Treatment strategy was not significantly associated with outcome, and 65.4% of cases had positive culture results, with Enterobacter cloacae as the predominant agent. Consolidation was observed in 81.8% of patients and was not significantly related to the outcome. ConclusionThere was a significant association between Makridis classification and the outcome. Consolidation rate was not associated with the outcome regarding the treatment of the infection.

Nd:YAG 1064 nm laser treatment for onychomycosis - is it really effective? A prospective assessment for efficiency and factors contributing to response.

Onychomycosis is a highly prevalent and persistent nail disorder primarily caused by dermatophytes. The effectiveness of current topical and systemic antifungals is limited by the extent and severity of the infection, patient demographics and health status, hepatic toxicity, drug interactions and low compliance. Laser therapy is a promising modality for safe and cost-effective removal of mycotic nail. This prospective study assessed the performance of a multi-series long-pulsed Nd:YAG 1064 nm regimen (30-40 J/cm2 , 1 Hz) in the treatment of 213 mycotic nails in 31 patients. Pain and discomfort were scored at each treatment session and mycological and clinical cure rates were determined 3 months after the last treatment session. Patients presented with mostly severe (mean SCIO score: 21.9 ± 8.9), T. rubrum-positive (87.1%) infections. Most (61%) had a family history of onychomycosis and a significant proportion had comorbidities, including hypertension (38.7%), hyperlipidemia (35.5%) and/or diabetes (12.9%). Treatment was well tolerated and there were no reports of nail deformity or burns. By 3 months post-treatment, mycological cure was achieved by 4 (12.9%) and visual improvements were noted for 10 (32.3%) patients, including 3 (9.7%) with moderate to significant improvements. Clinical response correlated with baseline SCIO ≤ 20 (OR: 0.9 [0.13-6.52]), family history of onychomycosis (OR: 0.27 [0.04-1.50]) and comorbidities (OR: 0.44 [0.05-3.74]). In conclusion, Nd:YAG 1064 nm laser is safe and effective for the management of mild-to-moderate onychomycosis in diverse populations. Further studies will be necessary to adjust treatment parameters to patient and nail profiles and to determine the impact of combined laser and topical therapies.

Staged Approach to Tibial Nail Removal Poses Increased Risk for Infection in the Setting of Total Knee Arthroplasty

BackgroundWhile previous research has addressed conversion arthroplasty scenarios, there is limited data on outcomes of staged or concurrent removal of intramedullary (IM) nails during total knee arthroplasty (TKA). Our study aimed to explore the association between the timing of IM nail removal and the incidence of periprosthetic joint infection (PJI), surgical site infection (SSI), manipulation under anesthesia (MUA), and aseptic revision at 90 days, 1 year, and 2 years after TKA when IM nail removal is performed in either a (1) staged or (2) concurrent manner. MethodsWe queried a national, all-payer database of all patients who underwent a primary TKA and hardware removal of an IM tibial nail. The group was separated into mutually exclusive cohorts with removal performed either (1) in a staged manner (n = 287) or (2) on the same day of TKA (n = 2,958). Surgical complications included the following: PJIs, SSIs, MUAs, and aseptic revisions. Surgical complications were collected at 90-day, 1 year, and 2-year time points. ResultsPatients who had staged nail removal before TKA demonstrated the highest incidence of PJI at 90 days, 1 year, and 2 years (13.9, 16.7, and 17.1%, respectively). Adjusted multivariate regression analyses demonstrated significantly higher odds of a PJI, SSI, and MUA at 90 days, 1 year, and 2 years for all patients who had staged nail removal TKA (P < .001). ConclusionsThere was an observed association between concurrent IM nail removal and a decreased risk of PJI, SSI, and MUA when compared to patients who had nail removal in a staged fashion. However, this does not discount the utility of the staged approach, as it may be necessary for patients less tolerant to longer operative times.

Removal of a Bent Humeral Intramedullary Nail: A Case Report and Review of Removal Techniques.

We present a case of a (65°) bent intramedullary nail (IMN) in a humerus after a pseudoarthrosis in a 65-year-old man. Bent IMNs have been described in femurs and tibias, but are considered rare. Possibly even rarer is the bending of a humeral IMN. This report provides an overview of removal techniques and our approach to this uncommon complication: open sectioning of the bent IMN and 2-piece extraction through the fracture site. Removal of a bent or broken IMN is a rare and challenging surgical problem. A bent humeral IMN requires a different and more careful approach for extraction than bent nails in the lower extremity, given the greater potential for neurovascular disruption.

Comparison of Efficiency and Effectiveness Between a Slap Hammer and Rigid C-Frame Device for Extraction of an Intramedullary Nail.

Removal of orthopaedic intramedullary implants can be difficult and time-consuming. Instrumentation for implant removal is frequently deficient for effective removal. The purpose of this study is to compare the efficiency of a C-type jig with a standard slap hammer attachment. We hypothesize that a C-type jig will be a more energy efficient method of implant removal. An IM nail removal was simulated in a series of 10 tests using 40 PCF Sawbones bone blocks with drilled holes and custom-made IM nails. Each attachment was secured to a Shukla Medical threaded connector from their IM nail revision product. A camera recorded each hammer swing, and a caliper recorded the distance the nail traveled out of the bone block. The data was then analyzed to determine extraction rate, and efficiency. The c-frame hammer exerted a greater force, had a greater extraction efficiency and required 37.4% less energy expenditure than the slap hammer to extract the nail the same distance. The C-frame hammer also removed the nail 38.1% faster with the same energy expenditure and possessed greater usable kinetic energy, whereas the slap hammer had more "lost" energy. The c-frame hammer attachment was found to have a considerably higher extraction rate and efficiency than the slap hammer. It will be a more useful method of implant extraction, especially for cases involving larger bones or larger implants. However, the slap hammer may be more suitable for smaller tools or bones for which larger impact loading would be detrimental.

Arthroscopically Assisted Suprapatellar Tibial Nail Removal

Intramedullary nailing remains the most popular and preferred method of fixation for tibial shaft fractures. The infrapatellar approach through the patellar tendon has long been considered the gold standard. However, the suprapatellar approach has gained popularity because of the advantages of being easier to perform when treating proximal shaft and metaphyseal fractures and there being less postoperative anterior knee pain. Despite increased use of this approach, the removal of the implant from the same suprapatellar approach is tricky, and in most cases, the removal is performed through a new transpatellar tendon approach. This article describes arthroscopically assisted suprapatellar tibial nail removal using the same approach and instrumentation of the nail insertion. The technique has the advantage of preserving the patellar tendon without causing secondary damage to it. Through arthroscopy, direct visualization of the patellofemoral joint aids in preventing possible cartilage injury. Moreover, any associated intra-articular lesions can be diagnosed and addressed.
