A Rare Case of Periprosthetic Joint Infection with Streptococcus dysgalactiae subspecies dysgalactiae.

Periprosthetic joint infection (PJI) is a rare but most vital complication after joint arthroplasty and requires a revision surgery. Synovial fluid analysis is essential in diagnosis of the PJI, and conventional and molecular microbiologic investigations may help in determining the cause of the infection. With this unusual case, we aimed to present the second instance in the literature of PJI of the knee caused by Streptococcus dysgalactiae subspecies dysgalactiae (SDSD). S. dysgalactiae PJI in the literature are commonly Streptococcus dysgalactiae subspecies equisimilis (SDSE), and SDSD mostly infects animals. A farmer with comorbid illnesses who works with cattle and sheep experienced periprosthetic knee joint infection caused by SDSD. Surgical excisional debridement with open washing, decompression, and liner exchange were performed. The identification of the bacteria was done with VITEK MS as SDSD. After 1-year follow-up, the patient has fully recovered without recurrence.

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.

Distal Humerus Metaphyseal-Diaphyseal Junctional Fracture of a Four-Year-Old Child Treated With Intramedullary Steinmann Wire Fixation: A Case Report.

Distal humeral metaphyseal-diaphyseal fractures are rare and inherently unstable injuries. Non-operative treatments can make it hard to maintain reduction. Open or closed reduction with percutaneous K-wire fixation may be the preferred treatment option for these fracture types. This case report describes successfully managing a rare distal humerus metaphyseal-diaphyseal junctional (MDJ) fracture in a four-year-old child using intramedullary Steinmann wire fixation. A four-year-old male child applied to the emergency service with a swollen elbow. He had a history of trauma 10 days ago. There was a long arm splint on his arm. A displaced distal MDJ fracture of the left humerus was detected on the radiograph. Due to its instability, we preferred surgical management. With a lateral incision, we obtained a successful reduction after manipulation. Subsequently, we achieved the anatomical reduction with three Steinmann pins. We applied two Steinmann pins intramedullary, and the other one crosses from the medial epicondyle and exits the lateral cortex, forming a crossed-pin configuration at the fracture site. We immobilized the extremity for four weeks with a long arm splint. At the end of the fourth week, we removed the Steinmann pins. After removing the wires, we began an active range of motion exercises. The plain X-ray at the two-month follow-up revealed good fracture healing with no residual elbow deformity. The patient could perform a complete elbow range of motion. The case highlights the challenges in treating pediatric distal metaphyseal-diaphyseal humerus fractures, and it demonstrates the effectiveness of this intramedullary Steinmann wire fixation technique in achieving stable fracture reduction and promoting rapid healing in a small child.

Simultaneous Talocalcaneal and Talonavicular Joint Dislocation With Navicular Bone Fracture of a Teenager While Playing Football: A Report of a Rare Case.

Simultaneous talocalcaneal and talonavicular joint dislocation, in other words, subtalar joint dislocation, and navicular bone lateral process fracture are rare orthopedic injuries. In this case, we aimed to discuss the effectiveness and ergonomics of non-surgical follow-up with a short leg splint after reduction of talonavicular, talocalcaneal joint dislocation, and lateral process fracture of the navicular bone. A 17-year-old male patient was admitted to the emergency department with swelling and pain in his left foot after spraining his left foot while playing football. Pain, swelling, and deformity in the left foot were evident without a neurovascular deficit. Radiographs showed simultaneous left foot talonavicular joint dislocation, talocalcaneal joint dislocation, and navicular lateral process fracture. The patient underwent closed reduction and a short leg splint. We followed the patient regularly, removed the leg splint in the fourth week, and started various movement exercises. We started muscle strengthening exercises in the sixth week and reached full range of motion with full muscle strength without any deformity in the eighth week. In this case, closed reduction and short leg splint with traction along the axis of the left foot and manipulation of the talus laterally by everting the ankle were sufficient. We restricted the movement of the ankle and tarsometatarsal joint with a short leg splint and reached full range of motion with follow-ups and exercises.

Simultaneous Fifth Carpometacarpal Joint Dislocation and Fourth Metacarpal Neck Fracture: A Conservative Treated Case With a Functional Metacarpal Splint.

Simultaneous carpometacarpal joint dislocation and fractures of adjacent carpal bones are rare orthopedic injuries. With this case, we aimed to discuss the effectiveness and ergonomics of the functional metacarpal splint in carpometacarpal joint dislocations and metacarpal neck fractures without surgery. A 27-year-old right-hand dominant male applied to the emergency department after a punch on a wall with his right fist. Pain, swelling, and deformity were evident without neurovascular injury. The radiographs showed simultaneous fifth carpometacarpal joint dislocation and fracture of the neck of the fourth metacarpal bone. We performed closed reduction with longitudinal traction and applied a functional metacarpal splint. We followed up with the patient regularly, and on the fourth week, we removed the splint and began a range of motion exercises. On the sixth week, we began muscle strengthening exercises, and we reached full range of motion with fair muscle strength on the eighth week of the follow-up without any deformity. In this case, prompt diagnosis, longitudinal traction, closed reduction with manual dorsal manipulation, and functional metacarpal splinting were adequate. We achieved a full range of motion without the need to immobilize the wrist or metacarpophalangeal joints or undergo surgery after proper immobilization with a functional metacarpal splint.

Ulnar Nerve Management in Distal Humerus Fracture Surgery: A Case of Developing Ulnar Neuropathy After Open Reduction and Internal Fixation.

In this case report, we want to show how a patient who underwent surgery for a distal humerus fracture developed postoperative ulnar neuropathy symptoms, how nonunion persisted even at the ninth month of follow-up, and whether the nonunion was connected to the ulnar neuropathy that developed. Due to this, we used this case to explore ulnar nerve care and whether ulnar nerve transposition, manipulation, or decompression should be carried out during surgery on patients with distal humerus fractures. A 52-year-old man with a bi-columnar distal humerus fracture from a fall on his right elbow underwent open reduction and internal fixation at an external center one year before. Elbow restriction, discomfort, numbness, and weakness in the fourth and fifth digits of the right hand were all symptoms the patient experienced eight months following the surgery. We discovered the distal right humerus' nonunion during the radiological exams. It became apparent that the patient had no signs of ulnar neuropathy before the injury. In the eighth month following the injury, the patient had implant removal, open reduction internal fixation with autograft, and ulnar nerve transposition. We discovered during follow-up that the patient's ulnar neuropathy symptoms had subsided. The surgeon's familiarity with the procedure and command of the anatomy of the elbow has a role in managing the ulnar nerve in distal humerus fractures. We concluded that more study is required to determine the connection between the onset of ulnar neuropathy and nonunion while treating distal humerus fractures.

Evaluation of patients' post-operative results operated for hip fracture with computerized dynamic posturography: Proximal femoral nailing versus hip arthroplasty.

BACKGROUND: Proximal femoral nailing (PFN) and hip arthroplasty (HA) are the two most often utilized surgical procedures for treating hip fractures in older patients. The post-operative postural balance and functional outcomes of patients may be significantly influenced by the technical distinctions between PFN and HA. This will influence the surgeon's preferred course of therapy. To examine the functional outcomes of patients treated with PFN and HA following a hip fracture, this study used computerized dynamic posturography (CDP). The aim of that study was to evaluate how the two treatment modalities affected patients' post-operative balance, postural stability, and functional rehabilitation. METHODS: A total of 26 patients who underwent proximal femoral surgery (15 patients PFN [58%] and 11 patients HA [42%]) due to hip fractures were evaluated at least 12 months postoperatively. They were tested by direct radiographs, hip joint examinations, Harris hip score (HHS), and CDP. RESULTS: Twelve (46%) of 26 patients were male and 14 (54%) were female. The mean age of the participants in the study was 67.9±14.2 years. The mean follow-up period was 24 (12-44) months. The average Harris score of PFN group was 79.3 (46.8-100) points and HA group was 83.7 (61.9-99.9) points. There was no significant difference between the groups in terms of Harris Score (P=0.54). The average of the mixed value of the balance results obtained with CDP (the Composite score) for PFN group was 70.5 (56-79) points, and for HA group was 71.9 (56-83) points. There was no significant difference between the groups in terms of the Composite Score (P=0.47). Accordingly, 12 (80%) of the patients who underwent PFN had good results and 3 (20%) of them had bad results. Eight (72.7%) of those who underwent HA had good results and 3 (27.3%) had bad results. There was no statistically significant difference (P=0.66). CONCLUSION: Comparing the composite score for balance results and HHS results for rehabilitation with the data of the patients who underwent PFN and HA, there was no statistically significant difference between these two techniques in terms of postural stabil-ity and balance as a result of CDP examination.

A Large Mass Displaying a Malignant Character on the Forearm: A Rare Case of Upper Extremity Pilomatrixoma.

In this study, a 50-year-old male patient had a painless swelling on his right forearm. The lump on the forearm started one year ago and increased in size in the last two months. The mass was 3x6 cm and had a malignant appearance on radiological imaging. The case was reported as pilomatrixoma in the histopathological examination after marginal excision. In this case report, we emphasized that pilomatrixoma is one of the diagnoses we considered in mass formations that can be seen in the upper extremity, although rare. The large mass displaying a malignant character in radiological imaging can be pilomatrixoma, and the Tru-cut biopsy before the final surgery may help diagnosis by preventing the surgeons from aggressive surgical treatment. The marginal excision shall be enough in the definitive treatment. With this study, we aimed to discuss the place of pilomatrixoma in the orthopedic literature, which is published chiefly by otolaryngology, pathology, and dermatology clinics and lacks in the orthopedic literature because it rarely involves the extremities.

Aspergillus fumigatus Septic Arthritis of the Wrist: A Report of a Rare Case in an Immunocompromised Patient.

Aspergillus fumigatus is a saprophytic fungus encountered as a pathogen in airborne lung infections. Although it commonly causes pulmonary infectious diseases, when disseminated, it may cause a systemic infection termed invasive aspergillosis, which is associated with high mortality and morbidity. Virtually, all organ systems may be involved. However, the musculoskeletal system is relatively uncommon. Here, we present a case of invasive aspergillosis in an immunocompromised patient involving the wrist joint, an exceedingly rare site. Our treatment choice is serial open debridement, irrigation, and intravenous antibiotics. This case study exemplifies the potential challenges in the identification and treatment of such an uncommon clinical condition. A thorough clinical and microbiological evaluation is essential for accurate diagnosis of fungal septic arthritis of the wrist. Aggressive early surgical treatment combined with appropriate early intravenous antibiotics is crucial for eradicating joint infection.

Match the Metatarsal Heads: A Case of All-Metatarsal Fractures After a Motorcycle Accident.

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.

A Case of Malignant Myxofibrosarcoma With Hypoglycemia Attacks.

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.

Management of Posterior Sternoclavicular Joint Dislocation in a Teenager After a Direct Elbow Strike to His Clavicle: A Case Report.

Posterior dislocation of the sternoclavicular joint is a rare orthopedic injury and may result in complications with high mortality due to the location of the joint, accompanied by neurovascular, tracheal, and esophageal injuries. Therefore, an immediate diagnosis and treatment are necessary to prevent complications. In this case, a 13-year-old male patient received an elbow strike to the left clavicle while playing football. The patient presented to the emergency department with complaints of pain, a gap and deformity in the superior and medial part of his sternum, and numbness in his left upper extremity. For this orthopedic emergency, which is difficult to recognize on direct radiographs, a computed tomography was done, which detected a left sternoclavicular joint posterior dislocation. A closed reduction procedure was performed on the patient under sedation in the operating theatre. A serendipity view with the fluoroscopy showed a successful closed reduction. A shoulder arm sling was applied and the patient was followed regularly. In the fourth week, the shoulder arm sling was removed and exercises were started to increase joint movements. In the sixth week, muscle strengthening exercises were started and in the eighth week, a full range of motion was reached with full muscle strength without any deformity. In this case, possible mortal complications were prevented with early intervention in the posterior dislocation of the sternoclavicular joint. This case report shows that with timely rehabilitation, it is possible to achieve full joint range of motion of the shoulder and full muscle strength without deformity or the need for surgery.

Bilateral Femur and Humerus Avascular Necrosis Associated With Corticosteroids: A Rare Case Presentation.

Avascular necrosis of the bone is a pathology characterized by compromised blood circulation, leading to necrosis due to insufficient vascular nourishment. Within the realm of orthopedics and traumatology, instances of avascular necrosis are steadily increasing. Notably, the escalating use of corticosteroids in managing inflammatory diseases and acute respiratory distress syndrome associated with the COVID-19 pandemic has resulted in a surge of outpatient referrals concerning cases of glucocorticoid-associated avascular necrosis. This study aims to elucidate the management of avascular necrosis following oral corticosteroid use in a young and otherwise healthy male patient, impacting both humeral and femoral heads bilaterally. A 26-year-old adult male, devoid of chronic health conditions, received a diagnosis of bilateral avascular necrosis in humeral and femoral heads within two years following a one-month course of oral corticosteroids. The patient underwent a comprehensive treatment regimen, encompassing hyperbaric oxygen therapy, oral antiplatelet therapy, a tailored physical therapy and rehabilitation program, and bilateral core decompression surgery for both hip joints. During the three-year follow-up, the patient exhibited a favorable response to treatment, demonstrating a complete and painless range of motion in both shoulder and hip joints. This case serves to underscore a crucial point: femoral head avascular necrosis may not invariably manifest as the initial bone affected, and a substantial time lapse may transpire between corticosteroid use and the onset of clinical symptoms. We emphasize the critical importance of not dismissing complaints pertaining to other bones in patients with a confirmed diagnosis and stress the significance of prompt detection in avascular necrosis. Furthermore, this study highlights the necessity for heightened vigilance in instances of orthopedic grievances among individuals with a history of corticosteroid use, particularly those related to the pandemic and inflammatory diseases, to facilitate early diagnosis and intervention for avascular necrosis.

Anatomical variations of intercostobrachial nerve: A potential candidate for neurotization after traumatic median nerve injury?

BACKGROUND: This study focused on the anatomical characteristics and variations of intercostobrachial (ICBN) nerve and median nerve to investigate the possible use of ICBN in restoration of sensory damage of hand after traumatic median nerve injury and to evaluate the feasibility of ICBN neurotization to median nerve. METHODS: Variations of ICBN were noted in 16 axillary region dissections of eight cadavers. Measurements for ICBN's suitability in terms of neurotization to brachial plexus were done with millimetric devices. The distance of ICBN to the distal end of the lateral (LCMN) and medial (MCMN) contributions of the median nerve and the diameters of ICBN, LCMN, and MCMN were measured. RESULTS: Fifteen axillary dissections exhibited ICBN, whereas it was absent on the left side of one of the cadavers. The mean diameter of ICBN at its origin was 2.0±0.7 mm and the mean diameter of ICBN at its coaptation point was 3.1±0.9 mm. The mean diameter of the LCMN was 3.9±2.0 mm, the mean diameter of MCMN was 3.5±0.9 mm. The length of ICBN was found to be adequate at both 45 and 90° of shoulder abduction to be extended to both LCMN and MCMN. The diameters of LCMN and MCMN were not significantly correlated with the diameter of ICBN both at origin and at coaptation point (LCMN: p=0.55-0.63 and MCMN: p=0.89-0.85). There is no significant difference between the diameter of LCMN and the diameter of ICBN at its coaptation point (p=0.168) and also between the diameter of MCMN and the diameter of ICBN at its coaptation point (p=0.232). CONCLUSION: All ICBNs dissected showed adequate length to reach the lateral and medial contribution of the median nerve directly. The ICBN could be a feasible candidate since its diameter was close to LCMN and MCMN according to the descriptive and inferential statistics.
