Google Bard and ChatGPT in Orthopedics: Which Is the Better Doctor in Sports Medicine and Pediatric Orthopedics? The Role of AI in Patient Education.

BACKGROUND: This study evaluates the potential of ChatGPT and Google Bard as educational tools for patients in orthopedics, focusing on sports medicine and pediatric orthopedics. The aim is to compare the quality of responses provided by these natural language processing (NLP) models, addressing concerns about the potential dissemination of incorrect medical information. METHODS: Ten ACL- and flat foot-related questions from a Google search were presented to ChatGPT-3.5 and Google Bard. Expert orthopedic surgeons rated the responses using the Global Quality Score (GQS). The study minimized bias by clearing chat history before each question, maintaining respondent anonymity and employing statistical analysis to compare response quality. RESULTS: ChatGPT-3.5 and Google Bard yielded good-quality responses, with average scores of 4.1 ± 0.7 and 4 ± 0.78, respectively, for sports medicine. For pediatric orthopedics, Google Bard scored 3.5 ± 1, while the average score for responses generated by ChatGPT was 3.8 ± 0.83. In both cases, no statistically significant difference was found between the platforms (p = 0.6787, p = 0.3092). Despite ChatGPT's responses being considered more readable, both platforms showed promise for AI-driven patient education, with no reported misinformation. CONCLUSIONS: ChatGPT and Google Bard demonstrate significant potential as supplementary patient education resources in orthopedics. However, improvements are needed for increased reliability. The study underscores the evolving role of AI in orthopedics and calls for continued research to ensure a conscientious integration of AI in healthcare education.

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.

Results and complications of bilateral limb lengthening in achondroplasia: a retrospective analysis.

Background: Achondroplasia is one of the main causes of disharmonic dwarfism. Patients with achondroplasia might have physical and psychological limitations due to their disproportionate stature. Surgical limb lengthening is the only practical option available to achieve a stature comparable to normal population range. The purpose of this study is to analyze results and complications of our lengthening protocol. Methods: A retrospective analysis was performed on 33 patients with achondroplasia (21 females and 12 males) undergoing simultaneous bilateral tibia or femur lengthening in four surgical stages from 2017 to 2021 (46 lengthening procedures, with a total of 56 tibias and 36 femurs). For each patient, patients' characteristics and antero-posterior and lateral radiographs were obtained. The following parameters were analyzed: duration of lengthening with external fixator, amount of lengthening, complications or events that influenced outcomes and the healing index (HI). Results: The average tibial and femoral gain was 7.9 cm and 6.9 cm, respectively. The tibiae achieved better results than the femurs (p = 0.005). Nineteen complications were reported for 92 segments (20.7%), and the variables influencing complications were: step (p = 0.002) and fixation duration (p = 0.061). Conclusions: Bilateral parallel lower limb lengthening in four surgical steps may be a viable technique in patients with achondroplasia.

Huntington procedure for the treatment of tibial nonunion in a 17-years old male: A case report.

INTRODUCTION: Bone is considered a tissue with good healing properties, and many bone defects can heal spontaneously under appropriate conditions. Extreme bone loss can hinder remodeling and regenerative processes, leading to bone nonunion. This condition negatively impacts the patient's quality of life with a severe socioeconomic burden. Many treatment options have been proposed, but none can be defined as a gold standard, mainly due to the variety of clinical presentation, bone loss, and quality. PRESENTATION OF CASE: We present a 15-year-old case of tibial nonunion following multiple traumas. The patient was treated non-surgically at the beginning, but the external fixator positioning was required due to a delay in the healing process. Following further trauma, the patient showed progressive anterolateral angulation, severe lateral procurvation, and a progressive worsening of the pseudoarthrosis. The severe bone loss and poor quality of the bone surrounding the defect required a special technique called Huntington procedure that consists in a vascularized bone autograft from the ipsilateral fibula to achieve mechanical and biological healing of the pseudoarthrosis. The patient recovered well and returned to full weight bearing without a mobility aid. DISCUSSION: We report this case of complex tibial nonunion and malalignment, developed after subsequent traumas. Due to the multiple complications, and the poor biology a Huntington procedure was required to provide mechanical stability and a biological boost to the bone defect. CONCLUSION: This case report shows a complicated case requiring several surgeries and treatment options and confirms the potential benefit of the Huntington procedure for treating a tibial severe bone loss.

Septic arthritis in the pediatric hip joint: a systematic review of diagnosis, management, and outcomes.

Septic arthritis of the pediatric hip joint (SAH) is a rare but serious orthopedic emergency requiring immediate diagnosis and management. Delayed recognition can lead to severe complications, emphasizing the need for timely intervention. This systematic review aims to provide a comprehensive analysis of SAH in the pediatric population, focusing on its diagnosis, management, and outcomes. The review included 11 studies involving 391 patients with SAH, aged between three months and 12 years. Staphylococcus aureus was identified as the most common causative pathogen, with increasing cases of methicillin-resistant strains. Diagnosis is challenging due to nonspecific clinical presentations, necessitating validated criteria and a multidisciplinary approach. Ultrasound emerged as a valuable tool for early detection, and MRI was used in challenging cases. Treatment options include hip aspiration, arthrotomy, and arthroscopy, often combined with appropriate antibiotic therapy. Success rates were comparable among different surgical procedures. Early intervention is vital for optimal outcomes. However, the review highlights the need for standardized protocols and further prospective studies to address limitations and improve understanding and management of SAH in the pediatric hip joint.

Role of the prophylactic fixation of contralateral unaffected hip in paediatric unilateral slipped capital femoral epiphysis: a systematic review.

The aim of this systematic review is to assess the role of the prophylactic fixation of contralateral unaffected hip in unilateral slipped capital femoral epiphysis (SCFE) in children, focusing on the possible complications of this surgical procedure. A systematic review of medical literature was conducted, according to the Preferred Reporting Items for Systematic review and Meta-Analysis (PRISMA) statement, to analyse the complications of prophylactic contralateral hip fixation in unilateral paediatric SCFE. We registered the complications reported in the included studies, scoring their severity according to the orthopaedic adaptation of Clavien-Dindo classification. From 1695 studies primarily identified, 14 studies were finally included: 1 prospective cohort study, 4 retrospective case-control studies and 9 retrospective case series, with a total of 811 children diagnosed with unilateral SCFE and treated on the unaffected contralateral hip. Grade IV complications were very rare (0.37%), while the rate of grade III events was 8%. No death was recorded. The most frequent complication was unplanned further surgery (6.29%) that was an epiphyseal refixation, owing to the physiologic growth of the proximal femur, in 42 cases. Cannulated screws fixation showed to have a lower major complication rate than pinning with K-wires, 5.37% vs 17.95%. The prophylactic fixation of contralateral unaffected hip in paediatric unilateral SCFE is a safe procedure. Although a benefit-cost analysis on this topic has not been published yet, considering the low rate of complications, prophylactic hip fixation is a viable option for patients presenting with unilateral SCFE, to prevent the occurrence of severe hip deformity and avoid future invasive surgeries.

Knee Pathology before and after SARS-CoV-2 Pandemic: An Analysis of 1139 Patients.

BACKGROUND: The SARS-CoV-2 pandemic drastically changed daily life activities and medical practice, leading to a reorganization of healthcare activities. People spent two months in home-isolation, changing their daily habits and undertaking a more sedentary lifestyle. Change in lifestyle is related to important consequences in knee pathologies. The aim of this study was to evaluate the outpatient activity for knee pathologies before and after lockdown in terms of incidence, severity, diagnosis, and treatment. METHODS: Medical records of patients with knee pathology in outpatient follow-up at IRCCS Istituto Ortopedico Galeazzi in Milan (Italy) were analyzed in the time frame 4 May-4 September 2020 and compared with patients examined between 4 May and 4 September 2019. RESULTS: A significant increase of knee diagnoses associated to patellofemoral disorders in 2020 was found (p = 0.004). In addition, physiotherapy was significantly more prescribed in 2020 than in 2019 (p = 0.012). CONCLUSIONS: The SARS-CoV-2 pandemic lockdown did not drastically change knee pathology, but it may have had an impact on it, highlighting a summary worsening of patellofemoral disorders associated with other knee diagnoses. Further studies are required to validate this result.

Effect of the COVID-19 Outbreak on Pediatric Patients' Admissions to the Emergency Department in an Italian Orthopedic Trauma Hub.

BACKGROUND: The rapid diffusion of Coronavirus disease (COVID-19) in Northern Italy led the Italian government to dictate a national lockdown from 12 March 2020 to 5 May 2020. The aim of this observational cohort study is to analyze the differences in the number of pediatric patients' admission to the Emergency Room (ER) and in the type and causes of injury. METHODS: The pediatric population during the pandemic was compared to a similar group of patients admitted to the ER in 2019. Sex, age, triage color-code at admission, cause of trauma and presence of symptoms related to COVID-19 infection, discharge diagnosis and discharge modes were investigated. RESULTS: The lockdown period led to a reduction of 87.0% in ER admissions with a particular decrease in patients older than 12 years old. Moreover, a trend towards more severe codes and an increase in home-related injuries were observed during the pandemic, whereas the diagnosis of fracture was less frequent in the pre-pandemic group (p < 0.0001). CONCLUSIONS: A significant decrease in the ER attendances was reported during the lockdown. A shift in the cause and type of injury was observed; only the most serious traumas sought medical care with a higher percentage of severe triage codes and fractures.

Resilience Against COVID-19: How Italy Faced the Pandemic in Pediatric Orthopedics and Traumatology.

BACKGROUND: We aimed to investigate the variation of medical and surgical activities in pediatric orthopedics in Italy, during the year of the COVID-19 pandemic, in comparison with data from the previous two years. The differences among the first wave, phase 2 and second wave were also analyzed. METHODS: We conducted a retrospective multicenter study regarding the clinical and surgical activities in pediatric orthopedics during the pandemic and pre-pandemic period. The hospital databases of seven tertiary referral centers for pediatric orthopedics and traumatology were queried for events regarding pediatric orthopedic patients from 1 March 2018 to 28 February 2021. Surgical procedures were classified according to the "SITOP Priority Panel". An additional classification in "high-priority" and "low-priority" surgery was also applied. RESULTS: Overall, in 2020, we observed a significant drop in surgical volumes compared to the previous two years. The decrease was different across the different classes of priority, with "high-priority" surgery being less influenced. The decrease in emergency department visits was almost three-fold greater than the decrease in trauma surgery. During the second wave, a lower decline in surgical interventions and a noticeable resumption of "low-priority" surgery and outpatient visits were observed. CONCLUSION: Our study represents the first nationwide survey quantifying the impact of the COVID-19 pandemic on pediatric orthopedics and traumatology during the first and second wave.

Recommendations from the Italian Society of Pediatric Orthopaedics and Traumatology for the management of pediatric orthopaedic patients during the COVID19 pandemic and post-pandemic period in Italy.

The rapid spread of the COVID-19 outbreak in Italy has dramatically impacted the National Healthcare System, causing the sudden congestion of hospitals, especially in Northern Italy, thus imposing drastic restriction of almost all routine medical care. This exceptional adaptation of the Italian National Healthcare System has also been felt by non-frontline settings such as Pediatric Orthopaedic Units, where the limitation or temporary suspension of most routine care activities met with a need to maintain continuity of care and avoid secondary issues due to the delay or suspension of the routine clinical practice. The Italian Society of Pediatric Orthopaedics and Traumatology formulated general and specific recommendations to face the COVID-19 outbreak, aiming to provide essential care for children needing orthopaedic treatments during the pandemic and early post-peak period, ensure safety of children, caregivers and healthcare providers and limit the spread of contagion.

Medium-term outcomes of total hip arthroplasty in juvenile patients.

BACKGROUND: Juvenile hip osteoarthritis is often the end result of congenital conditions or acquired hip ailments occurred during the paediatric age. This study evaluated the middle term results of total hip arthroplasty for end-stage juvenile hip osteoarthritis. MATERIALS AND METHODS: This is a retrospective analysis of prospectively collected data on a cohort of 10 consecutive patients (12 hips), aged between 14 and 20 at operation, who underwent cementless total hip arthroplasty for end-stage juvenile secondary hip osteoarthritis in two orthopaedic tertiary referral centres between 2009 and 2018. RESULTS: Juvenile hip osteoarthritis occurred as a consequence of developmental dysplasia of the hip, Legg-Calvé-Perthes disease, femoral head necrosis or slipped capital femoral epiphysis. All patients showed a significant improvement in Harris Hip Score (p < 0.01) at 3.3 years average follow-up (range 0.7-10.1 years). CONCLUSION: The management of juvenile hip osteoarthritis following developmental dysplasia of the hip, Legg-Calvé-Perthes disease, femoral head necrosis or slipped capital femoral epiphysis is still challenging. Careful preoperative planning is essential to achieve good outcomes and improve the Harris Hip Score in these young patients. Total hip arthroplasty is a suitable option for end-stage secondary juvenile hip osteoarthritis, when proximal femoral osteotomies and conservative treatments fail to improve patients' symptoms and quality of life. LEVEL OF EVIDENCE: IV.

Flexible Juvenile Flat Foot Surgical Correction: A Comparison Between Two Techniques After Ten Years' Experience.

The aim of our study is a retrospective analysis of the 2 most common surgical treatments of symptomatic juvenile flat foot: different arthroereisis techniques. Exosinotarsal arthroereisis with metallic screw and endosinotarsal with bioabsorbable devices were compared. In total, 402 feet were examined for a median follow-up of 130 months. Only symptomatic (plantar or calcaneus pain), flexible, and idiopathic flat feet were included in our study. Congenital (fibrous/bone tarsal coalitions), neurologic, and posttraumatic flat feet were excluded. During clinical examination, the feet were categorized according to the Viladot classification, which took into consideration the plantar impression: only grades 3 and 4 were included (complete medial longitudinal arch collapse). Evaluation was determined by taking into consideration 3 parameters: clinical evaluation, pain, and variation of the radiologic angles. No statistical differences were found between the 2 techniques; the choice can be determined mostly by the surgeon's preference.

Mesenchymal stem cells as adjuvant therapy for limb lengthening in achondroplasia.

Staged leg lengthening allows achondroplastic dwarfs to reach nearly normal height, but it takes long periods of external fixation and it can be burdened by delayed unions. Between 2009 and 2013, eight achondroplastic dwarfs showed delayed unions in the callus formation during femoral lengthening stages in our institute. We performed in-situ injections of bone marrow-derived stem cell concentrates. Patients underwent monthly clinical and radiographic assessment for determination of the healing rate. All eight patients showed an improvement in the regenerated bone, with an average healing index of 23.1 days/cm (range: 18.7-23.8 days/cm). The complete recovery of the delayed consolidation took on an average of 5.2 months (range: 2-10 months). The use of cellular therapy in these patients could represent an innovative application.

Autologous fat graft as treatment of post short stature surgical correction scars.

INTRODUCTION: Surgical limb lengthening is undertaken to correct pathological short stature. Among the possible complications related to this procedure, painful and retractile scars are a cause for both functional and cosmetic concern. Our team has already shown the efficacy of autologous fat grafting in the treatment of scars with varying aetiology, so we decided to apply this technique to scars related to surgical correction of dwarfism. A prospective study was conducted to evaluate the efficacy of autologous fat grafting in the treatment of post-surgical scars in patients with short-limb dwarfism using durometer measurements and a modified patient and observer scar assessment scale (POSAS), to which was added a parameter to evaluate movement impairment. PATIENTS AND METHODS: Between January 2009 and September 2012, 36 children (28 female and 8 male) who presented retractile and painful post-surgical scars came to our unit and were treated with autologous fat grafting. Preoperative and postoperative mean durometer measurements were analysed using the analysis of variance (ANOVA) test and POSAS parameters were studied using the Wilcoxon rank sum test. RESULTS: There was a statistically significant reduction in all durometer measurements (p-value <0.05) and in all but one of the POSAS parameters (p-value <0.05) following treatment with autologous fat grafting. DISCUSSION: Surgical procedures to camouflage scars on lower limbs are not often used as a first approach and non-surgical treatments often lead to unsatisfactory results. In contrast, our autologous fat grafting technique in the treatment of post-surgical scars has been shown to be a valuable option in patients with short-limb dwarfism. CONCLUSION: There was a reduction of skin hardness and a clinical improvement of all POSAS parameters in all patients treated. Moreover, the newly introduced POSAS parameter appears to be reliable and we recommend that it is included to give a more complete evaluation of patient perception.

Achondroplasia in female twins: surgical indications.

Although in literature achondroplasia has been described profusely, reports on achondroplastic twins are limited. We present two cases of monozygotic female twins with achondroplasia, who underwent limb-lengthening surgical procedure with external fixation in the following five steps: tibia, femur, tibia; femur, homer. Both the cases presented a good limb length and an optimal correction of associated deformities after the treatment, fulfilling the indications. Surgical indications were mostly led by the axial deviations of the lower limbs, and the timing of the limb-lengthening procedures has been the same in both couples showing the importance of this aspect.
