Allergic Contact Dermatitis in the Right Forearm Following Splint Application for Distal Radius Fracture: A Rare Case of Plaster Cotton Allergy.

Allergic contact dermatitis (ACD) after splint or cast application (plaster of Paris) is infrequently encountered in orthopedic and traumatology clinical practice. This case study aims to elucidate the identification of ACD after splint application, highlight the conditions that warrant vigilance, and outline the precautions and optional treatment methods available in such instances. A 56-year-old right-hand dominant female presented to the emergency department after a fall on her right hand, manifesting pain, swelling, and tenderness without neurovascular injury. Radiographs revealed a distal radius fracture, leading to the application of a plaster of Paris splint. Within one day, she returned to the emergency department with severe itching and burning in the right arm. The splint was removed, and a dermatology consultation confirmed ACD due to undercast cotton padding. After splint removal, the patient's fracture treatment continued using a shoulder-arm sling until the lesion healed. Topical antihistamine ointment and oral corticosteroids were prescribed. Regular follow-up revealed the healing and union of the fracture by the fifth week, with minimal residual skin color changes. This case underscores the importance of prompt diagnosis and appropriate treatment in managing such occurrences. A key takeaway is the crucial need to schedule a follow-up appointment with the patient within one day of applying the cast or splint. Skin problems can emerge rather than neurovascular issues following casts or splints. Educating patients on warning signs, including skin irritation, neurovascular deficits, and symptoms of compartment syndrome, ensures the timely identification of significant issues. Healthcare practitioners should inquire about patients' histories of allergic skin reactions, taking a proactive approach to prevent ACD through early intervention and preventive measures.

Are acromiohumeral distance measurements on conventional radiographs reliable? A prospective study of inter-method agreement with ultrasonography, and assessment of observer variability.

OBJECTIVES: This study aims to investigate the reliability of acromiohumeral distance (AHD) measurements using conventional radiographs and to compare non-standardized and standardized radiographs with intra-/interobserver reliability measurements. PATIENTS AND METHODS: Between February 2021 and January 2022, a total of 110 shoulders of 55 patients (25 males, 30 females; mean age: 49.7±12.6 years; range, 25 to 77 years) were included. Radiographs were taken in four different positions: primarily shoulder anteroposterior (AP), true AP, standardized true AP, and standardized outlet views. The AHD was measured by three orthopedists. A prospective ultrasonography (US) evaluation was performed by an experienced physiatrist, and the relationship between US and radiographic measurements was evaluated. The intra- and interobserver reliability of radiographic measurements was assessed. RESULTS: On the standardized true AP view measurements, all observers showed a moderate to good agreement with US measurements (intraclass correlation coefficients [ICC]: 0.68-0.75). There was no significant difference between the AHD measurements of the senior orthopedist on standardized true AP and outlet views, and the US measurements. The intraobserver agreement of US measurements was excellent (ICC: 0.98, 95% confidence interval [CI]: 0.98-0.99), and the intraobserver agreement level of measurements on radiographs were good to excellent with a wide range of ICC values (ICC: 0.79-0.97). Interobserver reliability was the highest on the standardized outlet view, with an ICC of 0.91 and 0.88 in two measurement times. Interobserver reliability of other measurements were good with ICC values ranging from 0.82 to 0.88. CONCLUSION: The AHD measurements on radiographs are compatible with US measurements within up to 2 mm difference if standardization is ensured. Also, measurements on standardized views have a superior consistency with lower standard error of measurement and minimal detectable change values. Therefore, we recommend using standardized true shoulder AP and standardized outlet radiographs in clinical practice and studies, as these are the most accurate in demonstrating true AHD.

Semimembranosus: A Rare Muscle Herniation and Review of the Literature.

Extremity muscle hernias are rare pathologies, most of which are managed conservatively. In symptomatic cases, surgical intervention may be required. This study represents a case of a rarer muscle hernia, semimembranosus, in a 43-year-old patient and describes the surgical technique of grafting with synthetic nonabsorbable polypropylene surgical mesh as well as the review of the literature about extremity muscle hernias.

The impact of COVID-19 pandemic in the first 100 days on orthopedic trauma surgery practice, the experience of a university hospital in Istanbul.

BACKGROUND: With the rapid and effective change created by the COVID-19 pandemic in all medical practice, we aimed to evaluate the impact of the first 100 days of the COVID-19 pandemic on the operations performed in a reference university hospital in the field of orthopedics and traumatology. Compare the results with the same period of the previous year and aim to evaluate importance of restrictions. METHODS: The operations performed in orthopedics and traumatology clinic between March 18, 2020 (the day we stopped the elective surgeries), and July 1, 2020 (when the normalization process began), were collected from the electronic archive to compare with the same period of 2019. RESULTS: Comparing the same periods of the year, it was seen that 102 surgeries were performed in the 2020 COVID-19 period compared to 380 operations performed in 2019. Although most of the operations performed during the COVID-19 period were traumas, the comparison revealed that trauma cases decreased by 25% from 73 to 58 (p<0.001). Among trauma patients operated in the restraint period, decrease in the pediatric group and the increase in patients over 65 years of age had seen statistically significant. Compared to the same period of the previous year, 50% increase seen in amputation cases related to diabetic foot (p<0.001). CONCLUSION: The postponement of elective cases due to the COVID-19 pandemic enabled us to manage trauma cases despite decreasing capacity utilization. In addition, it was observed that the transition of schools to online education and the implementation of curfews significantly reduced the number of trauma in the pediatric group. Separation of operating rooms and wards had a huge effect on protection of non-COVID patients. We hope that, in light of this study, we can guide health policies and help other colleagues to manage the possible new waves of the pandemic process or similar processes that may occur in the future.

The risk factors for mechanical complication in endoprosthetic reconstruction of knee osteosarcoma.

BACKGROUND: The increased limb survival rates and higher functional demands have also increased the mechanical complication rates of megaprostheses. This study aimed to analyse possible risk factors which can predispose patients to mechanical complications. METHODS: Patients with knee osteosarcoma referred to our clinic from 1992 to 2014 were investigated retrospectively. The patients who underwent surgical resection and endoprosthetic reconstruction with at least 5 years of follow up were analysed. The revision of the megaprosthesis due to a mechanical complication was accepted as an endpoint. The possible risk factors, including cement usage, implant material, joint mechanism, neoadjuvant radiotherapy, and anatomical localization of the lesion, were analysed for any association with mechanical complication rates. RESULTS: A total of 118 patients were included for final analysis. The average age was 24.5 years (standard deviation ±10.1, range: 15-64). Mechanical complication rate was 22% which included 19 aseptic loosenings and seven implant failures. The average time to mechanical complication was 32.5 months. Overall, 5-year implant survival was 78%. Multiple regression analysis revealed that cement usage is an independent risk factor for mechanical complication (P = 0.007). Although the 5-year implant survival was higher in rotating hinge and titanium implants compared with fixed hinge and cobalt chrome, the multiple regression model did not yield a correlation with mechanical complication rates. CONCLUSION: Cemented implants showed significantly higher mechanical complication rates compared with cementless ones in this series of knee osteosarcoma patients who underwent megaprosthetic reconstruction. Hinge mechanism and implant material did not have a significant effect on mechanical complication rates.
