■缺血性坏死(AVN)在腕部区域是罕见的,尤其是在三角骨,由于其频率低和缺乏创伤史,这提出了一个诊断难题。这个案例研究探索了这些迹象,诊断,以及在一个健康的22岁个体中治疗AVN,强调需要使用合适的成像方法进行早期识别。
■一名22岁的患者主诉持续的腕关节疼痛,特别是尺侧,没有任何受伤的历史。临床检查显示压痛,无炎症迹象,有正常的感觉和运动。最初的X光检查结果没有定论,促使MRI进一步调查,显示三角骨的信号强度下降,导致AVN的诊断。
■AVN的发展涉及血流受损,往往是由于各种因素。虽然影响腕骨的AVN并不常见,三角骨强大的血液供应通常可以防止这种情况。然而,这种情况突出了一个例外。Gelberman的分类强调了三角的血管性质,解释为什么AVN在这块骨头中很罕见。MRI在检测AVN中起着至关重要的作用,特别是当症状与X线检查结果不一致时。
■腕骨应考虑血管坏死,即使没有外伤史,专注于MRI早期检测。虽然三角的AVN很少见,此案强调了及时承认和保守管理的重要性。需要进一步的研究来为这种不寻常的表现建立最佳的治疗策略。
UNASSIGNED: Avascular necrosis (AVN) is a rare occurrence in the carpal region, especially in the triquetrum bone, which presents a diagnostic puzzle due to its infrequency and lack of trauma history. This case study explores the signs, diagnosis, and treatment of AVN in a healthy 22-year-old individual, emphasizing the need for early identification using suitable imaging methods.
UNASSIGNED: A 22-year-old patient complained of persistent wrist pain, specifically on the ulnar side, without any history of injury. Clinical examination revealed tenderness without signs of inflammation, with normal sensation and movement. Initial X-ray results were inconclusive, prompting further investigation with MRI, which showed a decrease in signal intensity in the triquetrum bone, leading to the diagnosis of AVN.
UNASSIGNED: The development of AVN involves compromised blood flow, often due to various factors. While AVN affecting carpal bones is uncommon, the triquetrum bone\'s robust blood supply typically protects against such conditions. However, this case highlights an exceptional occurrence. Gelberman\'s classification underscores the triquetrum\'s vascular nature, explaining why AVN is rare in this bone. MRI plays a crucial role in detecting AVN, especially when symptoms do not align with X-ray findings.
UNASSIGNED: Avascular necrosis should be considered in carpal bones, even without a history of trauma, with a focus on MRI for early detection. Although AVN of the triquetrum is rare, this case underscores the importance of timely recognition and conservative management. Further research is necessary to establish optimal treatment strategies for this unusual presentation.
