Coccygectomy for refractory coccydynia, old-fashioned but effective procedure: A retrospective analysis.

PURPOSE: Coccydynia, characterized by persistent pain in the coccygeal region, significantly impacts patients' quality of life. While various treatment modalities exist, including conservative measures and surgical interventions like coccygectomy, optimal management remains unclear. This retrospective cohort study aimed to compare the clinical outcomes, functional improvements, and quality of life in patients with chronic coccydynia undergoing either infiltrative treatment or coccygectomy. METHODS: Data from patients treated at our institution from January 2018 to December 2022 were analyzed. Participants meeting inclusion criteria were divided into two groups: Group A underwent coccygectomy, while Group B received conservative therapy. Clinical assessments, radiographic evaluations, and patient-reported outcomes were collected preoperatively and at follow-up intervals. RESULTS: Of the 223 initially examined patients, 55 met inclusion criteria. Group A (n = 21) underwent coccygectomy, while Group B (n = 34) received conservative therapy. Both groups showed significant pain reduction post-intervention, with sustained improvement in Group A. Functional outcomes favoured Group A, with significant improvements in disability and quality of life measures. Complications were minimal, with only one case of superficial wound infection in Group A. CONCLUSION: Our findings suggest that coccygectomy provides superior and lasting pain relief, functional improvement, and quality of life improvement compared to conservative therapy. While complications were minimal, further research with larger cohorts is warranted to validate these results and explore long-term outcomes. Despite its historical association with complications, advancements in surgical techniques and perioperative care have led to improved outcomes and reduced complication rates. Thus, coccygectomy should be considered in the treatment algorithm for patients with debilitating coccydynia.

Short-segment percutaneous fusion versus open posterior fusion with screw in the fractured vertebra for thoracolumbar junction burst vertebral fracture treatment.

Objectives: The treatment options for thoracolumbar junction burst fractures remain a topic of controversy. Short-segment percutaneous fixation (SSPF) and short-segment open fixation including the fractured level (SSOFIFL) are both viable procedures for managing these fractures. At present, there is a lack of evidence in the literature demonstrating the absolute superiority of one treatment over the other. This study aimed to compare these two surgical strategies with a focus on radiological and clinical outcomes. Materials and Methods: This retrospective case-control multicenter analysis involved patients with A3 and A4 vertebral fractures at the thoracolumbar junction (T11-L2) who underwent surgical treatment with either SSPF or SSOFIFL in the participating centers. Clinical outcomes were measured using the Oswestry Disability Index and visual analogue scale (VAS) both pre- and postoperatively. Radiological outcomes included kyphotic deformity (KD), anterior vertebral body height (AVBH), segmental kyphosis, and sagittal alignment parameters. Results: A total of 156 patients were enrolled in the study, with 81 patients in Group A (SSPF) and 75 patients in Group B (SSOFIFL). Group B demonstrated better correction of KD (Group B: 3.4 ± 2.7° vs. Group A: 8.3 ± 3.2°, P = 0.003), AVBH, and sagittal alignment. A minor loss of correction was observed in Group B with respect to Group A (0.9 ± 1.7° vs 4.3° ± 2.1°, P = 0.043). Blood losses were lower in Group A (78 ± 15 min vs. 118 ± 23 min, P = 0.021) as well as during surgery (121.3 ± 34 mL vs. 210.2 ± 52 mL, P = 0.031), but the post-operative hemoglobin levels were comparable between the two groups. Conclusion: SSOFIFL appears to show a major amount of KD correction and prevent loss of correction. This technique should be the preferred choice whenever possible. However, SSPF can be considered a valid alternative for damage control in polytrauma patients and fractures with low KD.

Post-traumatic instability of the first metatarsophalangeal joint: a novel surgical technique of capsular reconstruction in a young kickboxer.

Aim To report a novel surgical technique of capsular reconstruction of post-traumatic instability of the first metatarsophalangeal joint (MTPJ). Methods The clinical case is related to a 24-year-old male athlete whose clinical symptoms began with pain and spontaneous dislocation of the left first MTPJ during a kickboxing fight. He received conservative treatment (cryotherapy and rest) at first. Afterwards, he referred persistent hallux instability associated with moderate pain, despite normal anatomic alignment with no evidence of first ray deformity. Plain traditional x-rays of the left foot, magnetic resonance imaging (MRI), static and dynamic ultrasonography (US) and clinical tests were performed in order to diagnose capsular ligamentous structure lesions. Results The plain x-rays showed hallux abductus angle of 3°. The MRI and US demonstrated a rupture of the lateral capsular ligamentous structures and detachment of the abductor tendon. The pull out medium-lateral of the capsule with the abductor suture was performed as a treatment for dynamic hallux varus deformity. At six-month follow up, the patient walked without lameness with complete active and passive range of motion and with a stable first MTPJ. Conclusion The patient presented with the post traumatic instability of the first metatarsophalangeal joint treated with a novel surgical technique of capsular reconstruction. The patient returned to the full weight-bearing in only 2 months of rehab. To the best of our knowledge, the surgical correction proposed has not been previously described.

Choice of treatments of the coronal shear fractures of the humerus. A national survey of Italian AO members.

INTRODUCTION: Coronal shear fractures of the distal humerus are uncommon injuries representing 6% of distal humeral fractures. There is no univocal consensus about the correct management of this type of fracture. A national survey was conducted to gain more insight into the current classification, diagnosis and treatment of coronal shear fractures in Italy. MATERIALS AND METHODS: A postal survey was sent to all AO Italian members including residency orthopaedic surgeons. The survey consisted of general questions about personal experience in the management of these fractures: types of classification systems used, surgical approaches, treatment options and rehabilitation programs. RESULTS: 114 orthopaedic surgeons answered a 13-items questionnaire. The most used classification system was AO/OTA (72,8%). Independent screws and if necessary plates were the most answered regarding surgical treatment (81,6%). The most encountered post-surgical complication was stiffening of the elbow (81,6%). CONCLUSION: An algorithm of treatment has been proposed. To better classify coronal shear fractures, the authors recommended the integration of two classification systems: AO and Dubberley classifications. In the case of posterior wall comminution, a Kocher extensile approach is recommended, otherwise, if a posterior wall is intact, Kocher or Kaplan approach can be used. The posterior transolecranic approach can be reserved to Dubberley type III or AO 13B3.3. The best treatment choice is represented by independent screws and plates placed according to fracture patterns while arthroplasty is indicated when a stable ORIF is not possible. Mobilization is postponed for about 2 weeks.

Platelet Rich Plasma Injections for Knee Osteoarthritis Treatment: A Prospective Clinical Study.

Background: The aim of this prospective study was to evaluate the efficacy and safety of Platelet Rich Plasma (PRP) injections in patients affected by knee osteoarthritis (KOA). An autologous blood product containing a high percentage of various growth factors (GFs), cytokines and modulating factors as PRP has shown promising results in achieving this goal. Methods: One hundred and fifty-three patients (72 males, mean age 59.06 ± 8.78, range 40−81 years old) from January 2018 to January 2020 received three consecutive PRP injections and completed the follow ups. Western Ontario and McMaster University Osteoarthritis index (WOMAC), Knee society score (KSS) and Visual Analogic Scale (VAS) were evaluated before PRP injection (T0), one month (T1), three months (T2) and six months (T3) after the treatment. All patients underwent baseline and at 6 months MRI and X-ray evaluation. Results: A statistically significant VAS, KSS and WOMAC reduction emerged in the comparison between evaluations (p < 0.05), MRI demonstrated non-statistically significant improvement in cartilage thickness for both tibial plate and femoral plate (p = 0.46 and p = 0.33 respectively), and no radiographic changes could be seen in any patients. Conclusions: PRP injection represents a valid conservative treatment to reduce pain, improve quality of life and functional scores even at midterm of 6 months follow-up.

The determinants of positivization of anterior T-wave inversion in children.

BACKGROUND: Anterior T-wave inversion (aTWI) can be a common electrical sign in cardiomyopathies but also a benign feature regressing with age in healthy children. Unfortunately, little is known about the age of positivization of aTWI and its determinants in children and longitudinal data are not available. The aim of this longitudinal study was to identify the age and determinants of positivization of aTWI in healthy children. METHODS: ATWI was observed in 331 healthy children. They were evaluated yearly until positivization for a maximum period of 4 years. Positivization of aTWI was observed in 312 children (94%). The weight, height/length and their respective percentiles at birth and at the time of positivization of aTWI and weeks of gestation at birth were collected. RESULTS: Positivization of aTWI occurred at a mean age of 13.0±2.0 years. When aTWI became positive, most children had a height between 51° and 75° or over the 75° percentile. At the multivariate logistic regression analysis height, weight, percentiles of height and weight at the time of positivization were identified as the strongest independent predictors of the positivization of aTWI. No correlation was found for prematurity and anthropometrics characteristics at birth. CONCLUSIONS: ATWI is a common feature of pediatric ECG, usually regressing with age. Height, weight, percentiles of height and weight at the time of positivization were identified as determinants of TWI positivization. These simple anthropometric characteristics should be used in addition to chronological age in order to interpret aTWI in children.

The acute impact of an ultramarathon on right heart: A 12-lead ECG study.

BACKGROUND: Some concerns exist about possible detrimental effects on cardiac function of ultra-endurance competitions. The aim of this study was to evaluate the acute effects of an ultramarathon by comparing pre- and post-race 12-lead ECG features. METHODS: A total of 301 competitive athletes (mean age: 48 ± 9 years) running a 50-km ultramarathon were analyzed. Twelve-lead ECG was collected the day before the race and immediately at the finish line. According to the Italian law, athletes could have participated only after undergoing pre-participation screening that ruled out the presence of an underlying heart disease. RESULTS: After the race a significant increase in P-wave voltage (P < .001) and P-wave duration (P < .001) was found as compared to pre-race data with a higher percentage of athletes fulfilling the ECG criteria for right atrial enlargement (RAE; from 3% to 17%, P < .001). The presence of RAE post-race significantly correlated with age, hours of training/week, and years of training and inversely with time at the finish line and the final position in the ranking. T-wave and R-wave amplitude (P < .001) and QTc-interval duration (P < .001) significantly increased after the race. No significant differences in terms of supraventricular or ventricular arrhythmias were found. CONCLUSIONS: A sizeable proportion of athletes running a 50-km ultramarathon demonstrated post-race ECG signs of right heart overload but no arrhythmias. This finding supports the hypothesis that ultra-endurance races may induce transient right heart overload.

Normal and abnormal QT interval duration and its changes in preadolescents and adolescents practicing sport.

AIMS: Twelve-lead electrocardiogram (ECG) is an established tool in the evaluation of athletes, providing information about life-threatening cardiovascular diseases, such as long QT syndrome. However, the interpretation of ECG is sometimes challenging in children, particularly for the repolarization phase. The aim of this prospective, longitudinal study was to determinate the distribution of QT interval in children practicing sport and to evaluate changes in QT duration overtime. METHODS AND RESULTS: A population of 1473 preadolescents practising sport (12.0 ± 1.8 years, 7-15 years) was analysed. Each athlete was evaluated at baseline, mid-term, and end of the study (mean follow-up: 3 ± 1 years). QT interval was corrected with Bazett (B) and Fridericia (F) formulae. At baseline QT interval corrected with the Bazett formula (QTcB) was 412 ± 25 ms and QT interval corrected with the Fridericia formula (QTcF) 387 ± 21 ms, with no changes during follow-up. Ten children (0.68%) had an abnormal QTc. In those with QTcB and QTcF ≥480 ms, QTc duration persisted abnormal during the follow-up and they were disqualified. Conversely, children with 460 ms < (QTcB) <480 ms had a normal QTc interval at the end of the study. These children had also a normal QTcF. Mean difference in the calculation of QT between the two formulae was 25 ± 11 ms (P < 0.0001). For resting heart rate (HR) ≥82 b.p.m., QTcF was independent from HR contrary to QTcB. CONCLUSION: Normal QTc interval does not change over time in preadolescents. A minority of them has a QTc ≥480 ms; in these subjects, QTc interval remains prolonged. The use of Bazett and Fridericia correction formulae is not interchangeable and the Fridericia correction should be preferred in preadolescents with a resting HR ≥82 b.p.m.

Prevalence and significance of T-wave inversion in children practicing sport: A prospective, 4-year follow-up study.

BACKGROUND: T-wave inversion (TWI) is rare in athlete's heart but is a common manifestation in cardiomyopathies. Although TWI has been extensively investigated in adult athletes, the ability of this ECG pattern to distinguish between a physiological variant and a developing heart muscle disease in children is controversial. The aim of this longitudinal study was to establish the prevalence, changes and clinical significance of TWI in a large cohort of pre-adolescent athletes. METHODS: 2227 children (mean age 12.3 ±â€¯2.0 years) undergoing sports preparticipation screening were included. Children with TWI underwent yearly follow-up until the positivisation of TWI for a maximum follow-up of 4 years. RESULTS: Among 2227 children, 358 (16%) had TWI. Children with TWI were younger (11.4 ±â€¯2.1 vs. 12.5 ±â€¯2.0 years, p < 0.0001) and had a lower BSA than children without TWI (p < 0.0001). 97% of children showed anterior TWI while only 3% had infero-lateral TWI. Anterior TWI became positive in 94% of children during the 4-year follow-up (p < 0.0001 vs. baseline) and the remaining 6% did not show abnormal clinical findings. Conversely, in the group of 9 children with infero-lateral TWI, only 1 showed normalisation during follow-up (p = 0.81) and 1 was found to have a cardiomyopathy. CONCLUSIONS: Anterior TWI is common in children and generally becomes positive by the age of 14 years. Conversely, infero-lateral TWI is rare, persistent and may be associated with structural heart disease. Therefore, infero-lateral TWI should not be interpreted as physiologically related to age, development or training and children with infero-lateral TWI should remain under strict clinical surveillance.
