RESUMEN

Percutaneous tenotomy of the Achilles tendon is an integral part of the Ponseti technique of clubfoot correction. Although originally described by Ponseti as an office procedure that was performed under local anaesthesia, serious neurovascular complications that include iatrogenic injury to the lesser saphenous vein, the posterior tibial neurovascular bundle, the sural artery and pseudoaneurysm formation have been reported. We describe a new tenotomy technique, the posterior to anterior controlled technique, that may decrease the possibility of neurovascular damage, does not require exposure of the Achilles tendon and can be performed as an office procedure under local anaesthesia.

RESUMEN

Lengthening beyond 25% of the original segment length is an orthopaedic challenge. Substantial lengthening is fraught with complications such as joint contractures, refractures, nerve injuries and prolonged periods of consolidation. We report a case of massive lengthening in a 17-year-old boy in whom a 20 cm lengthening (57% lengthening) and complex deformity correction was performed on a centralized fibula using the Ilizarov technique, with an excellent result. A total of 17 months were taken to complete the process of lengthening and consolidation at a healing index of 0.85 months/cm. Besides a minor pin tract infection, there were no major complications. We believe that with meticulous pre operative planning and follow-up the extent of lengthening can be extended in cases of severe limb length discrepancy.

RESUMEN

OBJECTIVE: To evaluate the improvement in neurological deficit following late decompression and stabilization of the fractured thoracolumbar spine. METHODS: Between January 2001 and August 2004 neurological recovery in 120 thoracolumbar fractures was studied after posterior stabilization at the Hospital for Bone & Joint Surgery, Srinagar, India. There were 88 male and 32 female patients. Fall from a height, usually a tree, was the most common (90%) cause of injury. Seventy-six patients (63%) had neurologic deficit at the time of presentation. The unstable spine was fixed, between 4-18 days after trauma, by posterior short segment instrumentation (Steffee). Neurological recovery for the patients was recorded in the follow-up period. Frankel grade was used to assess the neurological status. The average follow-up period was 25 months (range 8-44 months), and average age was 34 years (18-54). RESULTS: There were 40 patients (30%) with an incomplete neurological deficit, namely, patients with Frankel grade B, C, and D. Two grades of improvement were found in 8 patients, and one grade improvement in 32 patients with incomplete lesion. Only one third of the patients with complete neuro deficit improved at the final follow-up. The overall result of the surgery for partial lesions was an improvement of at least one Frankel grade in all cases, but no improvement in most of the cases with complete lesion. CONCLUSION: This study demonstrates a clear relationship between the level of injury and Frankel grades, translational injuries are associated with a more severe neurologic grade, and surgical intervention appears to improve the neurological outcome, even when the intervention is inadvertently delayed (average 7.9 days).

RESUMEN

Fifty patients with thoracolumbar fractures were treated operatively between July 2000 and December 2001. The average age of the patients was 33.6 years (range: 20-50 years), 36 were males and 14 were females and the follow-up averaged 59 months (range: 49-68 months). A fall from a height, usually a tree, was the most common cause of injury. Twenty six patients had unstable burst fractures and 13 had translational injury. There were 15 patients with complete neurological deficit, 17 had partial neurological lesions, while 18 had no neurological deficit. All patients were treated by posterior short segment fixation (Steffee VSP). The average pre-operative kyphotic angle was 21.48 degrees , which improved to 12.86 degrees in the immediate post-operative period. The loss of kyphosis averaged 3.46 degrees (0-26 degrees ) at the final follow-up. The average pre-operative anterior vertebral body height was 44.7% (range: 36-90%), which improved to 72.0% (range: 55-97%) in the immediate post-operative period. The loss of body height averaged 3.0% (range: 1-15%) at the final follow-up. No neurological deterioration was seen, and in 24 cases a one grade or better improvement was observed. The mean pain score was 1.6, and the mean functional score was 2.8. We found that the application of posterior instrumentation resulted in a reasonable correction of the deformity with a significant reduction in recumbency-associated complications; there were, however, significant other complications.
