Premature partial physeal arrest without the formation of an osseous bar - physeal bar equivalent (PBE) - is uncommon. Four children with a PBE had an infection near the distal femoral physis before the age of 11 months. Some growth was achieved after resection of the PBE in each case. Of two cases diagnosed and treated early, one required only contralateral physeal arrests to achieve limb-length equality at maturity. The other, currently 8 years and 4 months old, has a 1.1-cm limb-length discrepancy 6 years after PBE resection and will require observation until maturity. Of two cases diagnosed and treated late, one required ipsilateral femoral lengthening and contralateral femoral shortening and physeal arrests to treat the limb-length discrepancy and angular deformity. The other, currently 7 years and 1 month old, has a 4.8-cm discrepancy and will need future surgical limb-length equalization. Early recognition and treatment of PBE is required to avoid severe limb-length inequality and angular deformity.
未形成骨桥的早发性部分骨骺阻滞——骨骺桥等效物（PBE）——并不常见。4例患有PBE的儿童在11个月龄之前，股骨远端骨骺附近发生了感染。每例在切除PBE后均有一定程度的生长。在早期诊断和治疗的2例中，1例仅需对侧骨骺阻滞即可在成熟时实现肢体长度相等。另1例目前8岁4个月，在PBE切除6年后肢体长度相差1.1厘米，需要观察至成熟。在晚期诊断和治疗的2例中，1例需要同侧股骨延长、对侧股骨缩短及骨骺阻滞来治疗肢体长度差异和角状畸形。另1例目前7岁1个月，相差4.8厘米，未来需要进行手术肢体长度均衡。需要对PBE进行早期识别和治疗，以避免严重的肢体长度不等和角状畸形。
