PURPOSE: We investigated if there was any change of the growth plate after recovery of bone length by distraction osteogenesis in the shortened long bone. MATERIALS AND METHODS: Three groups of 15 immature rabbits underwent shortening osteotomy of their right tibia by 20, 30, 40%, with minimal injury to the surrounding soft tissue, and distraction osteogenesis was performed to recover the original length. Radiographic, histomorphometric, and immunohistochemical studies were done to evaluate the activity of the growth plate. RESULTS: No significant difference was found between the lengths of both tibiae when the rabbits became mature. Three groups also showed no difference in the activity of the growth plate regardless of the amount of lengthening. CONCLUSION: These results suggest that distraction osteogenesis to recover the original length of bone does not disturb the physeal growth activity if the soft tissue envelope remains intact.

A femoral bone tumor causing a valgus deformity by affecting the growth plate was found. Long intramedullary diaphyseal tumor was separated by septum at the metapysis. Low grade chondrosarcoma was confirmed diagnosed by pathologists. Progressive limb deformity can be a sign of bone tumor in growing period.

The triplane fracture has been described as a fracture of the distal tibial epiphysis occurring across three planes-sagittal, transverse and coronal. The characteristic pattern of fusion of distal tibial epiphysis explains the special configuration of the fragments in the triplane fracture. According to Dias.Tachdjian classification, triplane fracture is classified two part fracture, three part fracture, four part fracture and two part fracture with extension to the medial malleolus. Among four types, two part triplane fracture with extension to the medial malleolus is a relatively rare injury and generally is not treated by closed reduction. Such fractures should have an anatomic reduction and adequate fixation to restore the joint congruity and obtain an anatomic reduction of the growth plate to prevent a future growth deformity. This is usually best accomplished with an open reduction and screw fixation or k-wire fixation. We experienced two part triplane fracture with extension to medial malleolus and check the CT to define the extent of the injury completely. And then we underwent open reduction and screw fixation for the fracture. As a result, we present four cases of two part triplane fracture with extension with review of related literatures.

The “delta phalanx”, first named by BlundeII Jones in 1964, is a triangular(“delta-shaped”) or trapezoidal phalanx with C-shaped epiphyseal plate causing progressive angular deformity of the digit with growth. Neither splinting nor physical therapy is effective in improving the condition. Surgical correction is indicated and several methods of correction have been reported. Authors have experienced a rare case of “delta phalanx” occuring in the proximal phalanx of the syndactylous digit.

To determine the characteristics of magnetic resonance (MR) signals of normal growing cartilage and identify the difference in transverse relaxation times between physeal and epiphyseal cartilage in vivo. 24 distal femora of 12 two-week-old piglets were imaged on a 1.5 Tesla GE MR scanner. Comparison was made between signal intensity on MR images and the structure shown in corresponding histologic sections. T2 values were measured in eight piglets by means of multiecho spin-echo sequences. Our results showed that MR imaging delineated five regions between the secondary ossification center and the metaphysis, which histologically correspond to the zone of provisional calcification of the secondary ossification center, physis of the secondary ossification center, epiphyseal cartilage, physis and zone of provisional calcification. The T2 value in the physeal cartilage was much larger than that in the epiphyseal cartilage (P<0.05). It is concluded that MRI findings could differentiate the different regions of growing cartilage. T2 is longer in physeal than in epiphyseal cartilage, perhaps reflecting differences in water binding by proteoglycans.

Histologically, Schmorl's nodes are defined as the loss of nuclear material through the cartilage plate, growth plate, and end plate into the vertebral body. Most Schmorl's nodes are asymptomatic, although there are some reports of symptomatic Schmorl's nodes, which should be treated similarly to vertebral compression fractures, with conservative treatment as the first choice. We report the case that we reduced the pain by blocking the ramus communicans nerve in a patient with Schmorl's node.
