■放射状发育不良,也称为radial球杆手,是指沿着手的纵向轴线的异常,其特征是radial骨结构的发育不全或发育不全。将腕部集中在尺骨远端的手术在解剖恢复方面具有相当好的效果,但影响腕部和手指的运动范围。四肢长度。我们进行了这项研究,以评估我们机构的连续铸造和集中化的结果。
我们进行了一项前瞻性研究,涉及20名儿科患者,有25条肢受BayneIII型和IV型放射状发育不良影响,平均随访时间为4.2年。每个肢体通过连续铸造进行渐进式软组织拉伸,其次是集中化。在手术和随访评估期间收集临床和影像学数据。
■该研究实现了径向偏差60°的平均校正,在随访期间,手腕的活动范围从79°减少到28°。手指活动性显示出增加的刚度。尺长恢复达到正常对侧的57%。最终结果,基于Bayne和Klug标准,发现25只手中有24只(96%)表现出良好或令人满意的结果。
■采用逐步矫正铸造,然后集中的早期干预是儿童radial骨发育不良的有效治疗方法。持续产生良好或令人满意的结果。然而,这种方法需要权衡减少手腕和手指的活动范围以及对肢体生长的潜在影响.
UNASSIGNED: Radial dysplasia, also termed radial club hand is an abnormality along the longitudinal axis of the hand characterized by hypoplasia or aplasia of radial structures. Surgery that centralize the wrist on the distal end of the ulna gives quite good results in terms of anatomical recovery but affecting range of motion of the wrist and fingers, limbs length. We conducted this study to evaluate the outcome of serial casting followed by centralization at our institution.
UNASSIGNED: We conducted a prospective study involving 20 pediatric patients with 25 limbs affected by Bayne Types III and IV radial dysplasia, with an average follow-up period of 4.2 years. Each limb underwent progressive soft tissue stretching via serial casting, followed by centralization. Clinical and radio-graphic data were collected at surgery and during follow-up assessments.
UNASSIGNED: The study achieved an average correction of 60° in radial deviation, with a decrease in wrist range of motion from 79° to 28° over the follow-up period. Finger mobility showed increased stiffness. Ulnar length recovery reached 57% of the normal contra-lateral side. Final results, based on the Bayne and Klug criteria, revealed that 24 out of 25 hands (96%) exhibited good or satisfactory outcomes.
UNASSIGNED: Early intervention employing gradual corrective casting followed by centralization is an effective treatment for radial dysplasia in children, consistently resulting in good or satisfactory outcomes. However, this approach entails a trade-off with reduced wrist and finger range of motion and potential implications for limb growth.
