RESUMEN
Thumb distal amputation refers to the loss of a portion of the thumb at or near the tip, which can be caused by various injuries such as crush injuries, lacerations, or avulsions. Several surgical methods can be used to repair thumb distal amputations, including composite graft, flap reconstruction, replantation, and amputation revision. In this case report, we describe a successful surgical procedure performed on three healthy men (19, 26, and 44 years old) who suffered a sharp amputation of their left and right hands thumb. In one case initial fixation of the amputated part was performed by a general orthopedic surgeon as a composite graft, two other cases were referred us without any procedure. The procedure involved irrigation and minimal debridement and deepithelializing the amputated part and fixation it with one or two 1.5 mm steinman pins and repairing the nail bed with7/0 absorbable sutures. An adiposofaciocutaneous flap from the index finger was used to cover the pulp of the thumb and the nail bed, while a full-thickness grafts from the same wrist in one case and medial part of ipsilateral arm in others were used to repair the defect on the dorsal side of the index finger. The wound was dressed, and the sutures were removed after two weeks. The base of the flap was detached from the index finger after three weeks, and the kwires were removed after six weeks. The flap and graft were successfully taken, except for a small part of the tip of the thumb. Two years after the operation, in two patients and 3 months in whom was operated recently, all the patient's thumbs had a reasonable shape and length with minimal nail deformity. The use of an index finger based adiposofaciocutaneous flap and full-thickness graft in these cases allowed for successful reconstruction of the thumb and, improving both function and appearance.
RESUMEN
Key Clinical Message: Giant cell tumor of bone (GCT) is a rare neoplasm which often presents as a lytic lesion in the epiphyseal region of long bones and which are usually accompanied by pain, swelling, and restricted movement. Abstract: Giant cell tumor of bone (GCT) is a rare neoplasm that affects individuals in their third and fourth decades of life. Clinically, it often presents as a lytic lesion in the epiphyseal region of bones, notably the distal femur and proximal tibia. Radiologically, GCT appears as a distinct lytic lesion in the epiphyseal region. Histopathologically, GCTs are composed of mononuclear cells, macrophages, and multinuclear giant cells, indicative of osteoclastogenic stromal tumors. A 37-year-old man presented with left wrist pain, swelling, and restricted movement persisting for a year, worsening over the last 7 months. Radiographic assessments revealed a distal radius bone mass involving the radiocarpal joint. Biopsy confirmed a GCT with extension into peripheral muscle. PET/CT scan showed localized pathology without metastasis. Histopathologically, GCT exhibited multinucleated giant cells, spindle cells, and aneurysmal bone cyst-like regions with coagulation necrosis. Surgical resection involved en-bloc removal and reconstruction with a non-vascularized radius bone graft. Postoperatively, the patient showed no complications at the one-year follow-up, suggesting successful intervention.
RESUMEN
Key Clinical Message: The modified nail folding approach, a new surgical technique, has been shown to be safe and effective for the treatment of subungual glomus tumors, providing clinicians with a new treatment option for patients with this condition. Abstract: Glomus tumors (GTs) are rare benign tumors that originate from the glomus body in the skin of the fingertips, toes, and nail beds. GTs are more prevalent in women than in men and can occur sporadically or as part of an inherited condition known as multiple GTs. The exact cause of GTs is unknown, but it is believed that mutations in the cells of the glomus body contribute to their development. In this study, we present the efficacy of a novel surgical technique called the modified nail folding approach for treating subungual GTs. We report a case series involving 17 patients who underwent the nail folding approach for surgical removal of subungual GTs. The primary objective of this article is to provide evidence supporting the safety and effectiveness of this technique. Additionally, we aim to introduce clinicians to a new, secure, and efficient treatment option for patients with subungual GTs.
RESUMEN
Osteochondromas (OCs) are developmental anomalies that originate from the periosteum and typically form during enchondral ossification near the joints. Retro-patellar OC caused by exostosis forms in various intracapsular, intra-tendon, and joint-adjacent positions within the knee joint. In this case, a 19-year-old male presented with swelling and a mass in his left knee, which raised suspicion of bone tumors. After evaluating x-ray images and conducting histopathological examinations, the diagnosis was confirmed as retro-patellar OC.

Key Clinical Message: Intramuscular myxoma (IMM) is a benign soft tissue tumor of mesenchymal origin that occurs mainly in skeletal muscles which can be removed through surgery after diagnosis. Abstract: Intramuscular myxoma (IMM) is a benign soft tissue tumor of mesenchymal origin that typically occurs in skeletal muscles. Its diagnosis is based on magnetic resonance imaging (MRI) and histopathologic evaluation of the lesion. In our report, we describe the case of a 60-year-old female with an IMM in the supinator muscle of the right forearm, which was confirmed by MRI and histopathologic examination. Following surgery to remove the mass, a follow-up confirmed the patient's recovery and the absence of movement limitations in the elbow joint.
