1/18. Spondylocarpotarsal synostosis syndrome and cervical instability.Spondylocarpotarsal synostosis syndrome is a recently delineated autosomal recessive condition comprising short stature with short trunk, failure of normal spine segmentation resulting in block vertebrae and fusion of posterior elements, carpal and/or tarsal coalition, scoliosis, lordosis, pes planus, dental enamel hypoplasia, decreased range of motion or dislocation of the elbow, renal anomalies, and hearing loss. The vertebral segmentation defects may involve noncontiguous areas of the cervical, thoracic, and lumbar spine. Odontoid hypoplasia was noted in two cases. We report on a sporadic case of spondylocarpotarsal synostosis in a 5-year-old girl with hypoplasia of C1 and odontoid and subluxation of C2 upon C3. This brings the number of well-documented cases of spondylocar- potarsal synostosis to 19, and is the first documenting cervical spine instability. Careful evaluation for this complication should be considered in other cases.- - - - - - - - - - ranking = 1keywords = motion (Clic here for more details about this article) |
2/18. Resection of talocalcaneal middle facet coalition. Interposition with a tensor fascia lata allograft: a case report.Tensor fascia lata is utilized in the management of complex soft-tissue injuries and defects, but has not been described in the literature in the use of tissue interposition with resection of talocalcaneal middle facet coalitions. This article is a case presentation of a resection of a middle facet coalition with interposition of an allograft of tensor fascia lata. At 14 months postoperative follow-up, range of motion of the subtalar joint was noted to be 20 degrees, and without pain or crepitus. There was no radiographic evidence of degenerative changes in Chopart's joint. The patient returned to all routine and sports activities without pain. He was satisfied with the outcome of the procedure.- - - - - - - - - - ranking = 1keywords = motion (Clic here for more details about this article) |
3/18. Posttraumatic radioulnar synostosis treated with a free vascularized fat transplant and dynamic splint: a report of two cases.Two cases of posttraumatic radioulnar synostosis are presented. The patients were treated with excision of the cross-union and interposition of a free vascularized fat transplant. A newly devised pronation-supination dynamic splint was employed for 3 months postoperatively in both patients. After a 1-year postoperative follow-up, an increased range of motion was restored in both cases, and there was no evidence of recurrent synostosis formation in subsequent radiographs. We suggest that an interposed vascularized fat graft may be an ideal biologic barrier to fill the space created by cross-union excision.- - - - - - - - - - ranking = 1keywords = motion (Clic here for more details about this article) |
4/18. Congenital radioulnar synostosis: a case report of a probable subtype.We present a case of bilateral congenital radioulnar synostosis in which computed tomography examination revealed osseous outgrowths of the ulna. Their excision resulted in 125 degrees range-of-motion of the forearm rotation.- - - - - - - - - - ranking = 1keywords = motion (Clic here for more details about this article) |
5/18. Unusual finding of the craniocervical junction.The authors report a rare anomaly of the upper cervical spine. After an automobile accident, an 8-year-old child underwent CT of the head. Imaging showed a bony anomaly of the neck that was further imaged with thin cuts through the atlas and axis. This demonstrated an unfused anterior arch of the atlas and fusion of the odontoid process to the anterior arch of the atlas. Neurologically, the child is normal with no decreased range of motion about the cervical spine. After a review of the literature, this seems to be only the sixth reported case.- - - - - - - - - - ranking = 1keywords = motion (Clic here for more details about this article) |
6/18. Distal tibiofibular synostosis and late sequelae of an ankle sprain.The late sequelae of an ankle sprain is described in the form of an acquired tibiofibular synostosis. A synostosis can result in loss of dynamic motion between the tibia and fibula, which may create decreased and painful ankle motion. A case report and surgical procedure is presented.- - - - - - - - - - ranking = 2keywords = motion (Clic here for more details about this article) |
7/18. Naviculo-cuneiform coalition--report of three cases.Naviculo-cuneiform coalition is a very rare condition and has only been reported by Lusby and Miki. We hereby describe three cases of this condition. The chief complaint was mild pain in the midfoot region especially after physical activity. There were no detectable deformities such as calcaneo-valgus, flatfoot or peroneal spastic foot, moreover the range of motion of the subtalar joint appeared to be normal. Conventional tomography confirmed coalition in two out of our three cases. 99mTc-MDP bone scintigraphy may be useful as a screening procedure. In past the pain associated with tarsal coalition was considered to result from the decreased range of motion in the fused joint due to ossification. However, our study have indicated that pain appeared to originate from the weakness of the cartilagenous bridges relative to the weight-bearing force over the naviculo-cuneiform joint.- - - - - - - - - - ranking = 2keywords = motion (Clic here for more details about this article) |
8/18. Triquetral-lunate arthritis secondary to synostosis.Until recently the problem of painful, symptomatic arthritis of the wrist secondary to congenitally incomplete separation of carpal bones has been infrequently recognized. Five patients with either excessive stress loading or trauma had eight symptomatic wrists with congenitally incomplete separation of the triquetral-lunate joint. Three of these patients had bilateral symptoms. Six of the wrists had been treated by a limited wrist arthrodesis of the triquetral-lunate joint resulting in asymptomatic wrists and improved range of motion. It appears that patients with this congenital condition poorly tolerate stress loading or trauma secondary to deficient intra-articular cartilage formation resulting in a clinical and anatomic state similar to degenerative arthritis. We suggest a limited wrist arthrodesis as definitive treatment for symptomatic congenitally incomplete separation of the triquetral-lunate joint, with possible application in incomplete separation of the other intercarpal joints.- - - - - - - - - - ranking = 1keywords = motion (Clic here for more details about this article) |
9/18. Radioulnar synostosis following an isolated fracture of the ulnar shaft. A case report.In the case of a 19-year-old man, overuse of his nondominant forearm resulted in a radioulnar synostosis. Despite the persistence of the synostosis, the patient adapted to loss of forearm rotation. No further treatment was necessary. Isolated fractures of the ulnar shaft are slow in healing. Several authors observed that early function may be beneficial. However, excessive activity causing motion at the fracture site may cause subperiosteal hemorrhage and soft tissue trauma and may stimulate exuberant callus formation. Fractures of the ulnar shaft, even undisplaced, need to be immobilized to prevent overuse.- - - - - - - - - - ranking = 1keywords = motion (Clic here for more details about this article) |
10/18. Congenital radio-humeral synostosis. A case report.In a 7-month-old male infant with congenital radiohumeral synostosis and associated absent first metacarpal, floating thumb, and hypoplasia of the humerus, the synostosis was resected. elbow motion was obtained and one year postoperatively there was no recurrence of the synostosis.- - - - - - - - - - ranking = 1keywords = motion (Clic here for more details about this article) |
