    An Uncommon Mass in The Distal Ulna; A Case of Atypical Osteoid Osteoma
    (Pera Yayincilik Hizmetleri, 2025) Barakat, Mohammed M. A.; Ertem, Kadir; Ozdes, Hueseyin Utku
    Osteoid osteoma (OO) is a benign osteoblastic tumor that commonly occurs in the diaphysis of long bones but is rarely found in peri-articular locations, particularly the wrist. This case report describes a 19-year-old female who presented with chronic wrist pain lasting two years, accompanied by nocturnal exacerbation and tenderness over the distal ulna. Imaging revealed a radiolucent lesion with a nidus, leading to a diagnosis of OO, later confirmed histologically following surgical excision. Differential diagnoses such as ulnar impingement syndrome, triangular fibrocartilage complex (TFCC) injuries, aneurysmal bone cyst (ABC), and giant cell tumor (GCT) were considered and ruled out through clinical and radiological findings. The patient experienced significant pain relief and regained full wrist function postoperatively. This report emphasizes the rarity of OO in the distal ulna and the importance of advanced imaging and a thorough differential diagnosis in managing persistent wrist pain.

    Chainsaw-Related Extremity Injuries
    (Mdpi, 2025) Ozdes, Hueseyin Utku; Ergen, Emre; Koroglu, Muhammed; Karakaplan, Mustafa; Acet, Omer; Al, Firat; Coban, Idris
    Background: Chainsaw-related injuries vary from skin lacerations to amputation and may cause serious loss of work time in addition to temporary or permanent disability. Most studies in the literature have reported injuries to the lower or upper extremities separately. The aim of our study is to compare the loss of work time between upper- and lower-extremity chainsaw-related non-occupational injuries in rural areas. Methods: Chainsaw-related injuries that occurred in rural areas and were treated in our center between 2012 and 2022 were retrospectively reviewed. The patients' demographics, the injured side and structures, the hand dominance of operators, lengths of hospital stays, the numbers of operations, complications, and loss of work time were recorded. Results: In total, 185 patients (181 males and four females) were enrolled in this study. The mean age was 45.5 years (range: 17-81). The mean follow-up time was 9.3 months (range: 6-24). The lower extremities were affected in 109 patients, while the upper extremities were affected in 76. The loss of work time was 60 and 75 days for lower- and upper-extremity injuries, respectively, and was statistically significantly higher for upper-extremity injuries (p < 0.001). The fracture rate was higher in the upper than the lower extremities, at 50% and 26.6%, respectively. Conclusions: Chainsaws may cause severe injuries in both the upper and lower extremities, and while the lower extremities were affected more frequently, upper-extremity injuries caused a greater loss of work time. Through the use of protective gear and simple precautions, chainsaw-related injuries and the associated loss of work time can be prevented.

    Use of nailfold capillaroscopy for the assessment of patients undergoing digit replantation and revascularization
    (Turkish Joint Diseases Foundation, 2024) Koroglu, Muhammed; Karakaplan, Mustafa; Zontul, Sezgin; Acet, Omer; Ozdes, Hueseyin Utku; Ergen, Emre; Aslanturk, Okan
    Objectives: In this study, we aimed to evaluate microvascular changes using nailfold capillaroscopy in patients who underwent digit replantation and revascularization. Patients and methods: A total of 46 patients (34 males, 12 females; mean age: 45.8 +/- 17.6 years; range, 18 to 75 years) who underwent replantation or revascularization procedures between February 2012 and May 2023 were retrospectively analyzed. Nailfold capillaroscopy images were assessed for various parameters including capillary count, diameter, dilatation, presence of giant capillaries, capillary disarrangement, microhemorrhages, neoangiogenesis, subpapillary plexus appearance, crossing capillaries, tortuosity, and microaneurysm. We investigated the association between microvascular alterations and clinical outcomes. Results: Of 46 patients, 25 patients underwent replantation and 21 patients underwent revascularization. Significant microvascular changes, including subpapillary venous plexus, microvascular enlargement, microhemorrhages, neoangiogenesis, and tortuosity were observed in replantation patients (p=0.000(b) , p=0.020, p=0.021(b) , p=0.001, and p=0.004, respectively). However, these changes were not significant in revascularization patients. Revascularization patients exhibited an increase in capillary diameter and disarrangement (p=0.019 and p=0.016(b) , respectively). A significant negative correlation existed between digital nerve repairs and microvascular enlargement in replantation patients. Hyperesthesia was significantly correlated with neoangiogenesis and capillary disarrangement, while a statistically significant positive relationship was found between subpapillary venous plexus and patient satisfaction in replantation patients. Conclusion: Our study showed that replantation patients who underwent two nerve repairs exhibited a well-regulated microvascular tone. However, we did not observe a statistically significant relationship between the number of nerve repairs and cold intolerance. Based on these findings, we highlight the potential of nailfold capillaroscopy in detecting microvascular changes following replantation and revascularization, which may contribute to a better understanding of the etiology of neurovascular complications.

    Wrist Arthroscopy-Assisted Coronal Hamate Fracture Treatment
    (Springer Heidelberg, 2025) Ozdes, Hueseyin Utku; Aslanturk, Okan; Ertem, Kadir
    ObjectiveWe present a case of wrist arthroscopy-assisted fracture treatment in a 39-year-old patient who underwent surgery for a coronal hamate fracture.MethodsWe performed intraoperative closed reduction and percutaneous headless screw fixation under arthroscopic guidance in a patient with a coronal fracture of the right hamate body and dislocation of the 5th carpometacarpal joint due to a fall. Dislocation reduction was achieved by applying traction to the fingers on the arthroscopy tower, and the fracture was visualized with a hook during compression under direct arthroscopic visualization.ResultsAlthough arthroscopy-assisted fracture treatments are frequently applied in larger joints, they are less common in smaller joints such as the carpal joints. Wrist arthroscopy, which requires experience, can yield successful results by enabling clear visualization of the joint and the fracture line in cases like coronal fracture-dislocation. Additionally, it encourages surgeons to perform closed fixation in selected cases and minimizes the risks associated with open surgery.ConclusionArthroscopy-assisted surgery for coronal hamate fractures provides advantages such as less soft tissue dissection and anatomical reduction, but it requires experience in wrist arthroscopy.
