Background: The standard approach for addressing intra-articular calcaneal fractures involves open reduction with plate and screw fixation, with ongoing discourse regarding the application of grafts to address bone gaps. The aim of this study is the temporal comparison of the radiological and functional outcomes in patients undergoing surgery for intra-articular calcaneal fractures, with a specific focus on the use of bone grafts. Methods: Thirty patients, comprising 13 with iliac grafts and 17 without, were enrolled in the study. Preoperative and postoperative assessments included Gissane and Böhler angles, Visual Analog Scale (VAS) scores, American Orthopedic Foot and Ankle Society (AOFAS) ankle hindfoot scale, and Kellgreen-Lawrance subtalar arthrosis stages. The average follow-up period was 6.7 years, ranging from a minimum of 3.5 to a maximum of 10 years. Results: The Böhler angle exhibited a significant increase ( p < 0.001), while the Gissane angle did not show significant changes in the early postoperative period across the entire study group ( p = 0.1). Graft-treated patients demonstrated a significantly higher Böhler angle in the early and late postoperative periods compared to preoperative values ( p = 0.04, p = 0.05). Similarly, patients without grafts exhibited a significantly higher Böhler angle in the early and late postoperative periods compared to preoperative values ( p = 0.004, p = 0.002). No significant differences were observed between periods in Gissane measurements ( p = 0.3), VAS scores, AOFAS scores, and the development of subtalar arthrosis in both grafted and non-grafted patients. Conclusions: Evaluation of patients with calcaneal fractures, both with and without grafts, was conducted using Böhler and Gissane angles, VAS scores, AOFAS scores, and the development of fracture union and subtalar arthrosis, assessing preoperative, early, and late postoperative periods. No significant differences were found between the two groups in terms of clinical and radiological outcomes during mid-to long-term follow-up. Level of evidence: A retrospective cohort study.

Metatarsal bone fractures are one of the most frequent foot injuries, especially after motor vehicle accidents in children. This case report briefly demonstrated a rare instance of pediatric all-metatarsal fractures of the left foot in an adolescent patient with polytrauma after a motorcycle accident. This case report illustrated the surgical procedure's potential for healing pediatric foot fractures in teenage patients after polytrauma. In the examination of a 16-year-old male patient brought to the emergency department after a motorcycle accident, we detected a right foot third finger proximal phalanx open fracture, right foot fourth finger proximal phalanx fracture, left foot first metatarsal proximal fracture, left foot second, third, fourth, and fifth metatarsal distal fractures, left foot cuboid, and navicular bone fractures. The patient's left foot's metatarsals were all fractured. The posterolateral wall fracture of the patient's right maxilla was also detected. All metatarsals were displaced, the second metatarsal paired with the third, etc., and because of this displacement, the closed reduction was impossible, and even the open reduction was challenging to reach the correct pairs. We performed closed reduction and fixation with Kirschner wire for the left foot's first metatarsal fracture and open reduction and fixation with Kirschner wire for the left foot's second, third, and fourth metatarsal distal fractures. We also performed closed reduction and fixation with Kirschner wire for the right foot third and fourth proximal phalanx fractures. We observed callus formation in the sixth week and removed the patient's K-wires. At eight weeks, the X-ray demonstrated the correct alignment of all metatarsals. The proper alignment of all metatarsals and the full range of motion of all foot and ankle joints were achieved with early surgical intervention, open reduction, and timely rehabilitation. This case also emphasizes the importance of open reduction in such irreducible and heavily displaced cases of multiple fractures as all-metatarsal fractures and contributes to the literature with a specific treatment modality in the case of all-metatarsal fractures lacking in the literature.

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.

This study addresses the challenges faced by diabetic patients undergoing lower extremity amputation due to diabetic foot, particularly focusing on the implications for wound healing and early mortality. The wounds at the amputation stump may necessitate multiple surgical interventions. The aim is to identify prognostic factors associated with these outcomes, shedding light on the complexities surrounding the postamputation phase. A prospective study was conducted on 39 diabetic patients who underwent lower extremity amputation due to diabetic foot between 2021 and 2022. Comprehensive preoperative data, encompassing parameters such as blood count, erythrocyte sedimentation rate, C-reactive protein, procalcitonin, hemoglobin A1c, albumin, protein, transferrin, ferritin levels, age, gender, body mass index, smoking habits, dialysis, revascularization, duration of surgery, and the use of tourniquet during the procedure were meticulously recorded. Additionally, cognitive performance and depression status were assessed preoperatively using the Mini-Mental State Examination (MMSE) and Beck Depression Inventory (BDI), respectively. A follow-up period of 3 months postsurgery allowed for the comparison of patients who developed infections at the amputation stump with those who did not, as well as the distinction between patients who survived and those who succumbed to mortality. The study revealed that the use of a tourniquet during surgery significantly increased the risk of infection (p = .027), and higher BDI scores were associated with increased risks of both infection (AUC = 0.814) and mortality (AUC = 0.769), with cut-off scores of 24.0 and 23.5 predicting these outcomes with high sensitivity and specificity, respectively. Additionally, lower MMSE scores were associated with increased short-term postoperative mortality. There were no statistically significant differences between the groups in parameters such as complete blood count, ESR, CRP, procalcitonin, HbA1c, albumin, total protein, transferrin, ferritin levels, age, gender, BMI, smoking, dialysis, revascularization, and surgery duration. This investigation highlights the significance of considering tourniquet usage during amputation, preoperative depression status, and cognitive function in patients who undergo amputation due to diabetic foot. The use of a tourniquet during surgery is a significant risk factor for infection, and elevated BDI scores are strong predictors of both infection and mortality in patients undergoing amputations. The findings underscore the importance of a multidisciplinary neuropsychiatric evaluation preoperatively to enhance patient care and outcomes. (http://creativecommons.org/licenses/by-nc-nd/4.0/)

Post-traumatic elbow stiffness poses a complex challenge, often attributed to intrinsic and extrinsic factors. Heterotopic ossification (HO) is a significant extrinsic contributor, leading to contracture and entrapment syndromes. This study explores the pioneering strategy of total resection and reconstruction of the ossified and contracted collateral ligament in managing extensive HO-induced elbow stiffness. Our goal was to show that complete collateral ligament excision and reconstruction result in a wide range of motion and no long-term HO or elbow instability. Six patients with severe elbow stiffness underwent HO resection and extensive soft tissue release. Two of them underwent a single fraction of radiotherapy, receiving a dose of 7 gray within the 24 hours preceding the surgery. Five patients with extensive medial HO underwent medial collateral ligament reconstruction using palmaris longus autografts in four of them and tensor fascia lata autograft in one of them, and one patient underwent lateral collateral ligament reconstruction with palmaris longus autograft after lateral collateral ligament sacrifice. Anterior transposition of the ulnar nerve was carried out for all patients to prevent postoperative ulnar nerve symptoms. Evaluations included preoperative and postoperative elbow flexion/extension arcs and Mayo Elbow Performance Score. The study included six patients with stiff elbows (five males, 1 female), aged 17- 45 years (mean age: 30 years). Injury patterns included three nonvehicle traffic accidents and three trauma-related injuries. The trauma-to-surgery interval ranged from 6 to 288 months, with a mean of 79.17. Three patients required intensive care unit stays before surgery, while the other three did not, suggesting varying causes of HO development. After an average follow-up of 3 years, patients exhibited improved flexion/extension arcs (122.5°) from a mean preoperative 20°. The mean Mayo Elbow Performance Score improved from 21.67 preoperatively to 98.33 postoperatively. None of the patients reported varus or valgus instability. Our study demonstrates that excision and reconstruction of the ligament with HO can be a viable and reliable solution for elbow joint stiffness, particularly when the wide HO involves collateral ligaments and loosening procedures are deemed insufficient. Our approach proves cost-effectiveness compared to alternatives involving suture anchors or external fixators, with the added advantage of facilitating more flexion and extension postoperatively to preserve the achieved range of motion.

Myxofibrosarcoma is a malignant mesenchymal tumor and a fibroblastic sarcoma of the elderly. Myxofibrosarcoma can be low-grade or high-grade depending on the cell characteristics. Wide surgical resection with or without radiotherapy and chemotherapy is the basis of its treatment. Sometimes, tumor cells secrete insulin or insulin-like substances and cause hypoglycemia attacks. Here, we intend to demonstrate the role of early surgery to end hypoglycemia attacks and prevent recurrence and metastases. We also intend to show the insufficiency of tru-cut biopsy to distinguish between low- and high-grade myxofibrosarcoma. An 82-year-old male patient visited our clinic with a rapidly growing giant mass in the left retroscapular area and suffered from hypoglycemic attacks several times a day. After imaging and initial biopsy, the tumor grade was indeterminate on histopathological examination; hence, the mass was removed surgically. The pathological examination resulted in high-grade myxofibrosarcoma whereas the initial biopsy could not elaborate on the grade. The hypoglycemia attacks ceased after the surgery. Adjuvant local radiotherapy at a total dose of 60 Gy was administered in 30 fractions to the surgery area with no complications after the surgery. No new mass, recurrence, or hypoglycemia attack was detected in the three-year follow-up. In conclusion, hypoglycemia attacks may be a marker of malignant tumor presence and may be a clue at the beginning and in the follow-up period both for recurrence and the aggressiveness of the tumoral mass. Because a biopsy may show the diagnosis but not the grade of the tumor, early surgical intervention is needed.
