[Association of Wolff-Parkinson-White syndrome with isolated non-compaction of the left ventricle: a case report].

The Wolff-Parkinson-White syndrome (WPW) may be associated with a number of cardiac pathologies, especially congenital disease, in 7.5 to 17% of cases. The authors report a rare association of the WPW syndrome with two Kent bundles, right and left septal, with non-compaction of the left ventricle in a 52 year old man. This was a chance finding during systematic echocardiography after ablation, and confirmed by cardiac MRI. The patient was asymptomatic.

A memory coiling spiral as nucleus pulposus prosthesis: concept, specifications, bench testing, and first clinical results.

The intradiscal cavity left after a discectomy can be filled by a new nucleus prosthesis made of polycarbonate urethane in the form of a "memory coiling spiral." Biomechanical tests have demonstrated that this device compensates for the loss of disc height, decreases the compression of the facet joints, and restores the kinematics of the spinal segment, without deformation of the vertebral endplates or migration. The device is currently under clinical investigation. Inclusion and exclusion criteria of the pilot study are presented, and preliminary results of the first five patients supplied with the spiral are reported after an average follow-up time of 24 months. No migration of the device has been observed so far. With its easy application due to the standardized approach and the memory coiling mechanism, this device represents an advance within the nonfusion techniques.

A spiral implant as nucleus prosthesis in the lumbar spine.

Microdiscectomy represents the gold standard in disc surgery on the lumbar spine. The remaining defect in the intervertebral disc space can be filled with a newly developed nucleus prosthesis presented in this paper. This prosthesis consists of polycarbonate urethane (Sulene PCU), and takes the form of a memory coiling spiral. It can be easily implanted using the standard microdiscectomy approach with no further tissue damage. Biomechanical tests have shown that anatomical distances can be restored by the spiral for both the facet joints and the endplates. Endplate deformations are not statistically different when compared to intact conditions. Inclusion and exclusion criteria of an in vivo pilot study are presented. The paper describes the insertion setup for the spiral and the technique of implantation. Five patients have been supplied with the implant to date. The first results on postoperative magnetic resonance images are presented.

Hypercapnia during transperitoneal and retroperitoneal endoscopic spinal surgery: a prospective study.

STUDY OBJECTIVE: To evaluate the effect of carbon dioxide (CO(2)) pneumoperitoneum and retropneumoperitoneum insufflation on CO(2) excretion. DESIGN: Prospective study. SETTING: Operating room and recovery room in a teaching hospital. PATIENTS: 29 patients scheduled for orthopedic spine fusion surgery. INTERVENTIONS: Patients received either transperitoneal insufflation (n = 12) or retroperitoneal insufflation (n = 17). MEASUREMENTS AND MAIN RESULTS: Increases in the partial pressure of end-tidal CO(2) (PetCO(2)) and arterial CO(2) tension (PaCO(2)) during retropneumoperitoneum exceeded those obtained during pneumoperitoneum. Furthermore, PetCO(2) increased faster during retroperitoneum and did not reach a plateau. Finally, 76% of the patients in this group required ventilatory adjustment due to high PetCO(2) levels. CONCLUSIONS: This study may focus attention on the need for continuous ventilatory adjustments during transperitoneal endoscopic surgery.

Use of tissue expansion in revision of unhealed below-knee amputation stumps.

When local tissue is insufficient for the revision of unhealed below-knee stumps tissue expansion offers an interesting alternative for local coverage. We used this method in seven patients (five men, two women; mean age 30 years) who had had below-knee amputations, six of them after injury to a healthy limb and one for purpura fulminans. Ten tissue expanders were inflated slowly and intermittently either weekly or twice weekly depending on the patients. The mean expansion period was 92 days. Mean hospital stay for the two operations was 5.8 (range 4-9) and 7.6 (range 6-10) days, respectively. Using subjective and objective criteria, functional outcome was excellent in five patients and good in one. Expansion failed in one because of infection. Expanded skin flaps allow good cover with a minimal scar area in appropriate cases, while preserving the skin sensitivity and length of the tibial shaft.

[Treatment results of fractures of the patella using pre-patellar tension wiring. Analysis of a series of 203 cases].

Two hundred three fractures of the patella in 200 patients were treated by tension band wire fixation using one or several wire loops and 2 longitudinally directed Kirschner wires. They were reviewed with a mean follow-up of six years (range 1 to 10 years). There were 143 men and 57 women. Age at operation averaged 36 years (range 18 to 83 years). The most frequent etiology was a road traffic accident. The fractures were simple in 35.5%, slightly comminuted in 37%, and very comminuted in 27.5% of cases. Thirty-four fractures were open, and there were other associated fractures in 35 cases (17%); 12 fractures (6%) were seen in polytrauma patients. The operation was performed on the first day in 63 cases (31.5%), between 2 and 8 days following trauma in 112 cases (56%), and after the 8th day in 25 cases (12.5%). The authors used 2 Kirschner wires in 81 cases (40%), 3 in 73 cases (36%), and more than 3 in 49 cases (24%). A single wire loop was used in 99 cases and a modified tension band wiring in 104 cases; passive mobilisation of the knee was started on the second day after operation, and weight bearing was allowed after five days, except when there were associated lesions. The complications were sepsis in 11 cases (5%), loosening of material in 20 cases (10%), malunion in 9 cases (4.5%), nonunion in 8 cases (4%), femoropatellar osteoarthritis in 17 cases (8.5%). The results were excellent or good in 169 cases (83%), and fair or poor in 34 cases (17%). The authors recommend this operative technique which allows good anatomic reconstruction of the patella, early mobilisation of the knee and early weight-bearing with a high rate of consolidation.

[Interbody arthrodesis of the lumbar vertebrae using retroperitoneal videoendoscopy. A preliminary study of 38 cases].

AIM OF THE STUDY: To report a series of 38 patients presenting retroperitoneoscopic inter-body fusion of the lumbar spine from L2 to L5, performed between 1995 and 1998. PATIENTS AND METHODS: This series included 25 women and 13 men aged from 16 to 74 years (mean age: 48.5 years). Surgery was performed in 32 patients for primary degenerative or post-operative instability of the lumbar spine, in five patients for painful sequels of burst fracture, and in one patient for sequels of disc infection. The main complaint was lumbar pain but a real sciatic pain was present in nine patients and was not a contraindication for this surgery. Standard X-rays were performed for each patient, and MRI performed in 30 patients confirmed the diagnosis and was also useful in determining vascular abnormalities. A cast immobilisation of the lumbar spine was done as a preoperative test in every patient. RESULTS: Forty-two levels were fused: 31 with a cage filled with cancellus bone and screwed between the end plates, and 11 with cancellus bone alone or in association with bone substitute, such as beta TCP. Post-operative complications included only a transient paresthesia of the thigh in two cases and a chyloretroperitoneum spontaneously resolutive. After 2.3 months of plaster immobilisation with a follow-up of 11.4 months, patient satisfaction rate was 84.5%, with 68.5% reporting no further back pain. The improvement was estimated by Prolo score. Fusion was considered effective by X-ray examination in all patients with an increase in the intervertebral space of 35% and a recovery of the local lordosis of 15%. CONCLUSION: Retroperitoneoscopic surgery is an elegant and secure method for lumbar interbody fusion of L2 to L5 with very few postoperative complications.

[Extensive pseudotumoral lumbar spine lesions of vascular origin].

Extensive remodeling of the anterior aspect of the lumbar spine was observed in two patients with a ruptured aneurysm of the abdominal aorta. Both patients survived as the rupture was contained in the first case and involved a false anastomotic aneurysm in the second. The patients presented with a clinical picture compatible with advanced stage cancer and a radiologic aspect showing anterior erosion of the vertebral bodies, suggestive of very advanced spondylodiscitis. The diagnosis was made on the basis of ultrasound and CT-scan evidence. There was no parallel relationship between the size of the ectasia and the spinal remodelling. A hypothetical pathogenic mechanism involving the intermittent pulsation of the aneurysm and ischaemia of the vertebral bone is proposed.

[Study of the correlation between magnetic resonance imaging and surgery in the diagnosis of chronic Achilles tendinopathies].

Eighteen cases of chronic lesions of the heel cord were evaluated by MRI and operated. The sensitivity of MRI is high in detecting intratendinous lesions (positive predictive value of 0.94); this sensitivity is linked with an unsurpassed anatomical precision. The specificity in the diagnosis of intratendinous lesions is limited as regards partial rupture versus chronic inflammation. This technique can be improved by systematically making fine cuts in the transverse plane, absolutely perpendicular to the heel cord.

[Iliac eventration after posterior iliac bone removal. An original technique of reconstruction].

A tricortical bone graft removal from the iliac crest causes a parietal defect that may be complicated by iliac or iliolumbar eventration, according to the extent of the bone loss. On the basis of their experience with a particularly characteristic clinical case, the authors describe an original reconstruction technique. The surgical techniques aimed at parietal restoration described in the literature include either the use of foreign materials or of those provided by the patient (skin, fascia lata, etc.), or the use of the surrounding anatomical elements to reconstruct a solid wall. Most of these procedures may be difficult to implement if the loss of substance is extensive, or in a posterior site. Thus, in order to prevent possible recurrence in case of major bone defects, we propose to combine the cure of the eventration with a restoration of bone continuity with a cold-conserved allograft and the reconstruction of the musculoaponeurotic curtain by the translation of the lumbosacral fascia. This procedure allowed obtaining a very satisfactory result, which was stable after 18 months both as regards parietal reconstruction and as regards pain, owing to the restoration of balance in the paraspinal muscular support.

Symptomatic spinal epidural lipomatosis induced by a long-term steroid treatment. Review of the literature and report of two additional cases.

Spinal epidural lipomatosis associated with Cushing's syndrome is an uncommon complication (11 reported cases). Two additional symptomatic cases with neurologic deficit are described. Steroid treatment was systemic in the first case and local with epidural injections in the second. The second case is unique because no similar observations have yet been reported. In most cases, a preoperative computed tomographic scan establishes the diagnosis by demonstrating dural compression by an adipose mass. Myelography is far less specific. In some cases, the exact diagnosis is made at the time of surgery. The treatment is primarily surgical, with laminectomy over the length of the compression and the removal of the compressing fat. Neurologic recovery is dependent on two factors: the level of the compression and the adequacy of decompression.

[Recurrent postoperative sciatica. Prospective evaluation of magnetic resonance imaging and x-ray computed tomography with iodine injection].

The respective performance of MRI and CT were studied prospectively in 80 cases. Surgery was indicated in 56 patients after MRI examination and 21 patients after CT; the 21 patients were included in the 56. Among these patients, 45 were reoperated and 11 preferred the medical treatment. Surgery confirmed the diagnosis for 44 patients (from the 45), and the only discordance was the presence of ligament calcification, associated to a disc protrusion not seen on MRI. Surgery confirmed also the diagnosis for the 21 cases diagnosed by CT after iodine injection. However, among the 24 cases of fibrosis diagnosed by CT after i.v. injection were found: 19 recurrent disc protrusions, 4 disc protrusions with fibrosis, and 1 disc protrusion at a level above the operated disc.

Recurrent postoperative sciatica: evaluation with MR imaging and enhanced CT.

Magnetic resonance (MR) imaging and computed tomography enhanced with intravenous iodine injection (ECT) were prospectively compared in 80 patients in the diagnosis of recurrent postoperative sciatica. Diagnostic accuracy was determined with surgical verification. Isolated fibrosis was considered a contraindication to surgery. A decision to operate was made in 56 of the 80 patients on the basis of MR imaging findings; in 21 of the 56, the decision was also made on the basis of ECT findings. Of the 80 patients, 45 underwent surgery, In all but one of these patients, the diagnosis made on the basis of MR imaging findings was confirmed with surgical analysis. The only surgical finding that did not agree with MR imaging findings was a calcification of the common posterior ligament. The 21 diagnoses of disk herniation based on ECT findings were confirmed surgically, but among the 24 diagnoses of fibrosis made with the help of ECT, there were actually 19 recurrent herniations, four herniations with fibrosis, and one herniation at the level above the previously resected disk. MR imaging seems to be the investigation of choice in diagnosing the cause of recurrent postoperative sciatica.

[Syndrome of compression of the external saphenous nerve (or the sural nerve)].

The authors describe a new canal syndrome, which they call the "superficial sural aponeurosis canal syndrome" or "sural nerve tunnel syndrome". Mostly seen in sportsmen, it was observed in this case in the context of a myositis ossificans circumscripta of the tendo-muscular junction of the heel. The clinical signs are caused by compression of the sural nerve where it passes through a nonextensible tunnel formed by the fold of the posterior sural aponeurosis. This is distinguished from a loge syndrome; the most typical clinical sign is increased pain in the territory of the sural nerve during plantar flexion of the ankle; in this position reduced sensory conduction velocity is measured. The treatment consists in a section of the fibro-aponeurotic arch.
