Synostosis*

The congenital radio-ulnar synostosis is a rare malformation which often completely perevents pronation and supination of the forearm. Recently, this disese has no good result by treatment including various operative techniques. The authors have experience a case of the congenital radio-ulnar synostosis, which was corrected by modified Green method and satisfactory result was obtained.

Antley-Bixler syndrome is a very rare disese of characteristic feature of craniosynostosis, brachycephaly, midface hypoplasia, depressed nasal bridge, radiohumeral synostosis and bowing femur. We presented a case of Antley-Bixtler syndrome with brief review of lituratures.

PURPOSE: Forearm lengths in cases of unilateral congenital radioulnar synostosis, were analysed radiographically to evaluate the amount of length discrepancy according to different types. MATERIALS AND METHODS: We measured the ulnar length ratio (length of affected forearm/length of unaffected forearm) in 15 cases of uni-lateral congenital radioulnar synostosis. We observed two distinct radiographic patterns. Type I (Lamda type) appeared to be of gamma character grossly, and showed severe radial bowing and a severely hypoplastic radial head. Type II (Chi type) seemed x like in character, showed mild radial bowing and a mildly hypoplastic, or normal radial head. RESULTS: Nine cases were type I and 6 were type II. The ulnar length ratio was 0.89 in type I and 0.98 in type II. Significant differences were formed in the ulnar length ratios between normal subject and type I, and between type I and type II (p<0.05). The equation determined by simple linear regression analysis in a patient of type I, who had been followed for 10 years, was'ulnar length ratio=0.959-0.013 X age (year)'. CONCLUSION: Unilateral congenital radioulnar synostosis can be classified into two types according to radiological morphology. This classification can be helpful in the prediction of forearm length discrepancy, and in the determination of surgical treatment type.

OBJECTIVE: The purposes of this study are to compare imaging features with operative findings and to determine significance of imaging studies for early detection of craniosynostosis(CS). METHODS: Plain radiograph of skull and three-dimensional(3D) CT reconstruction were analyzed in 10 consecutive patients with CS to assess the presence and the extent of synostosis. The radiological findings were investigated and compared with operative findings. RESULTS: The locations of lesion were coronal suture in 6, sagittal suture in 3 and multiple sutures in one patient, and the age ranged 1 to 53 months(mean age: 17.4 months). Reconstructive procedures with or without advancement of supraorbital rim were performed in coronal CS patients and PI-procedures or synostectomy were done in sagittal CS patients. Radi-ological abnormalities such as sutural indistinctness or sclerosis, bony ridge, bossing and other bony deformities were nearly consistent with surgical findings. CONCLUSION: The interpretation of imaging study are very important for early detection of craniosynostosis, especially, the plain radiographs of skull. Also 3D CT imaging is helpful in diagnosis and surgical planing of craniosynostosis. There are no significant differences between imaging features and operative findings in CS patients.

PURPOSE: Lambdoid synostosis can be found unilaterally, bilaterally or in combination with other forms of craniosynostosis. Based on concept of frontoorbital advancement, we used the technique of occipital advancement in order to correct lambdoid synostosis MATERIAL & METHOD: From 2002 to 2006, standardized occipital bandeau advancement with barrel stave osteotomy was performed in two children who had multiple synostosis. The surgery was carried out for patients 12 & 18 months of age. RESULTS: Aesthetically satisfactory skull shape and normalization of the intracranial pressure could be achieved. A major complication in the form of life-threatening intraoperative hemorrhage and other complications such as infection have not occurred. CONCLUSION: Standardized occipital Bandeau advancement with barrel stave osteotomy allows precise, reproducible and predictable positioning of the segments. Artificial sutures are created as a result of the osteotomy. Remodeling leads to a well-proportioned skull shape and posterior advancement leads to an increase in intracranial volume.

PURPOSE: To assess the usefulness of the talocalcaneal C sign in the diagnosis of subtalar coalition, as seen on lateral radiographs of the ankle. MATERIALS AND METHODS: Lateral radiographs of 12 ankles in 11 patients were included in this study. Twelve subtalar coalitions were confirmed by surgery (n=6), or by CT and/or MR (n=6). The presence of the talocal-caneal C sign on lateral ankle radiographs was determined. RESULTS: The C sign was continuous in six feet and interrupted in the remaining six. Subtalar coalition occurred simultaneously in the middle and posterior subtalar joints in two cases, the posterior subtalar joint only in six, and in the middle subtalar joint only in four. In six cases confirmed at surgery, subtalar coalitions consisted of both synostosis and non-osseous fusion (synchondrosis and/or syndesmosis) and in one case of middle subtalar coalition, there was a bony bridge. The remaining six cases, confirmed at CT or MRI, involved both synostosis and non-osseous fusion (n=1) or non-osseous fusion only (n=5). CONCLUSION: In the diagnosis of subtalar coalition, the talocalcaneal C sign, seen on lateral radiographs of the ankle, is a useful indicator.

Tarsal coalition is an abnormal union between two or more bones of the hind- and mid-feet, which can occur at various rates from cartilaginous to osseous union. Talonavicular coalition is reported less frequently than calcaneonavicular or talocalcaneal coalition and has been associated with various abnormalities, including symphalangism, clinodactyly, ray anomaly, clubfoot, other tarsal coalitions, and a ball-and-socket ankle joint. Patients with talonavicular coalitions are usually asymptomatic and rarely require surgical treatment. We review the literature and report on a case of 59-year-old male patient with talonavicular coalition.

The most common cause of proximal radioulnar synostosis in adults is traumatic, usually after forearm fractures. Disabling complications are mainly loss of rotatory movements of the forearm. Various surgical procedures have been described in the literature to end up in forearm synostosis as a complication. We here presented a rare case of proximal forearm synostosis following a common but improper surgical technique for an olecranon fracture complicated by implant infection. The synostosis was treated by resection and fascia lata interposition graft.
