Chronic recurrent multifocal osteomyelitis causing spinal cord compression.

Chronic recurrent multifocal osteomyelitis (CRMO) is a very rare condition of unknown etiology and most commonly occurs during childhood or adolescence. The purpose of this paper is to present a case of CRMO in a vertebral location with severe kyphosis, spinal cord compression, and neurological dysfunction requiring anterior decompression and fusion. After 12 weeks, the patient was physically able to return to school. At 2-year follow-up, neurological and functional outcomes are fair. Magnetic resonance imaging shows good restoration of the sagittal spine alignment despite residual mild kyphosis, and restoration of a normal sagittal diameter of the spinal canal.

Ipsilateral omovertebral bones in the levator scapulae muscle and the rhomboid muscle in a Sprengel deformity: case report.

Our interest was stimulated by the uncommon case of a 4-year-old girl who presented a Sprengel deformity associated with two omovertebral bones on the same side. The first omovertebral bone was situated in the levator scapulae muscle and the second omovertebral bone was lying in the rhomboid muscle. The removal of these two bones was combined with a Woodward procedure to obtain a good correction.

Brachialis arteria rupture following closed posterior elbow dislocation. Case report and literature review.

Although isolated posterior closed elbow dislocation occurs frequently, associated disrupted brachialis arteria is an uncommon complication which is rarely encountered. The rarity of this complication makes adequate management of this injury controversial, but arterial reconstruction remains the treatment of choice and is recommended despite reports of success following simple arterial ligation. Complications such as intermittent claudication or gangrene of the hand are possible if brachial artery flow is not restored.

[Anterior spinal fusion by thoracoscopy. A non-traumatic technique].

PURPOSE OF THE STUDY: Video assisted thoracic surgery (VATS) is a new modality which allows visualization of, and access to the intrathoracic organs without thoracotomy. Recently, this technique has been used for anterior thoracic spine approach to perform surgery which previously required standard postero-lateral thoracotomy. The authors report their initial experience of anterior spinal fusion using thoracoscopy and give a detailed description of their surgical procedure. MATERIAL AND METHODS: This technique, started on June 1993, was performed only in one level 1 in 10 patients who had thoracic spine trauma with fracture or luxation. The procedure was performed in the lateral decubitus position. The patient was prepared in the standard manner for a full thoracotomy. Surgical instruments that are needed for conversion to an open procedure must be in the operative room. Ventilation was stopped to the ipsilateral lung. Lung's collapse of the surgical side was obtained with a double lumen tube. Carbon dioxide (CO2) insufflation was used to further collapse. The first thoracoscopic portal was placed through the sixth or seventh intercostal space in the posterior axillary line, which was the safest place. All subsequent portals were placed under thoracoscopic visualization, in a triangular way as recommended by Landreneau (1992). Only open trocars were used to avoid complication of CO2 insufflation. Once the target level has been defined, a needle was placed into the disc space and roentgenographic confirmation obtained. The parietal pleura was then divided using monopolar electrocautery. Segmental vessels of the operation field lied transversely across the midportion of the vertebral body. They were mobilised and systematically ligated with endoscopic clip to simplify the procedure. Then the intervertebral space was opened and bone and disc were removed, restricted to the anterior and middle third. The graft was placed into the thoracic cavity by using a high density calcium hydroxyapatite ceramic block. Peroperative radiologic control ascertained the good position of the implant. At the end of the procedure a chest tube was placed through the lower trocar site and the lung re-expanded. A post operative CT Scan controlled good position of the graft and complete lung expansion. Contra-indications for VATS are previous surgical procedures or empyema causing extensive pleural adhesions. Procedures not appropriate for VATS approach are some that require anterior instrumentation for stabilisation, burst fracture, or fracture with posterior wall involved. RESULTS: The planned procedure was accomplished in all but one patient who required conversion to an open procedure because of segmental artery bleeding. Mean operative time was 1 h 45 mm, and mean estimated blood loss was 650 cc. There was no complication from CO2 insufflation neither postoperative complication. With an average of 2 years follow up, anterior grafting is as good as an open technique, radiologic evaluation according to Uchida (1990) showed good incorporation of each block without any radiolucent line or displacement. DISCUSSION: According to literature this technique was performed safely in 10 cases, especially without any respiratory complications and chronic pain (impairement of pulmonary function, re-expansion failure, incisional complications, rib fractures, chronic pain and malfunction of the chest wall, limitation of shoulder girdle motion) which are considered to be the main disadvantage of traditional thoracotomy. Many authors previously used VATS for multi level thoracic discectomy for correction of spinal deformities (Mack 1995), spinal reconstructive surgery (Mac Afee 1995) or removal of protrude thoracic disc (Rosenthal 1994). CONCLUSION: This original technique demonstrates that thoracoscopy for anterior thoracic surgery is better for the patients, reducing surgical trauma of the chest wall and to the lung parenchyma (in term of post operative comfort, sh

[Scaphoid and lunate palmar divergent dislocation. Apropos of a case].

UNLABELLED: A case of palmar dislocation of the scaphoid and lunate which where dissociated from each other is reported with a 3.5 years follow up. A 32 years old man fell while reading his motorcycle. He landed on his left hand dorsiflexed. There was no skin dilaceration and neuro-vascular status of his hand was intact. X-rays showed a palmar dislocation of the scaphoid and lunate with a large gap between the two bones. The lunate was also completely dissociated from the triquetrum and the capitate. Distal pole of the scaphoid remained in contact with the trapezium. The patient was taken to the operating room, and after unsuccessful closed reduction, an open reduction through a palmar approach was performed. A complete disruption of the anterior capsule was founded and all perilunate ligaments were completely disrupted. Reduction was easy under direct vision, and the anterior capsule was repaired. A non displaced trapezium fracture seen at surgery was fixed with a Kirschner wire. A long arm cast applied for 6 weeks. At 3.5 years follow-up, the patient had an almost full range of motion and no residual pain. Power grip was 25 per cent reduced in comparison with the opposite side. X-rays showed a palmarflexed scaphoid and Magnetic Resonance imaging showed no evidence of avascular necrosis. DISCUSSION: Simultaneous dislocation of scaphoid and lunate as a unit or with a large gap between the two bones are extremely rare injuries. In all cases already reported, results were briefly presented without any available clinical and radiological data because patients were lost for follow-up. In our case report, the anatomy and kinematics of the wrist showed the lack of our initial treatment with a single volar approach, anterior capsular reparation and a long arm cast alone. In fact, at 3.5 years follow up, ligamentous healing was inadequate to control compressive forces across the wrist and the scaphoid volarflexed despite a good alignement in the cast. Although the functional results is good, radiological outcome is far from being good. This case demonstrated that even in early treatment with a good position of carpal bones in the sole cast, healing of the ligamentous system without loosing reduction is difficult. CONCLUSION: In such a case, and with a low rate of avascular necrosis in perilunate dislocations treated early we suggest an open reduction and internal fixation (O.R.I.F.) to prevent carpal instability. We recommend combined volar and dorsal approaches for repairing anterior and posterior ligaments (especially interosseous ligaments on both sides of the lunate), associated with a stabilization of the entire carpum by scapho-lunate, triquetro-lunate, and capito-lunate Kirschner wire fixation.

[Surgical approach to the axillary nerve via an anterior trans-coracoid route].

The surgical approach to the circumflex nerve is difficult. Based on an illustrative clinical example, the authors describe a method using a coracoid osteotomy that permits a simplified approach to the circumflex nerve. This trick permits en bloc retraction of the superficial plane of the brachial plexus without sectioning of the muscle and without excessive traction on the musculocutaneous nerve. The stable fixation of the coracoid at the end of the procedure permits early and effective rehabilitation.

[The thoraco-lumbar junction. Orientation of zygapophyses, mamillary process and vertebral rotation].

The orientation of the zygapophyseal joints at the thoraco-lumbar level is an important factor involved in the axial rotation of the human spine. The functional role of the Mamillary Processes (MP) is unknown. This study was carried out on 55 adult dried spines. The aims were 1) to record the interzygapophyseal joint angles. 2) to determine morphological and functional angle types. 3) to correlate the various types and the corresponding MP lengths. 4) to propose hypotheses about the MP role. There were 2 distinct morphotic types founded on 2 different populations of angles clearly visible on histograms at the T12 level and statistically detectable at the T11 and L1 levels. T11-T12-L1 realized an homogeneous anatomical unit with 2 separate groups depending on the zygapophyseal joint orientations. A functional classification was also possible depending on the location of the geometric axial center of rotation. The "thoracic" type which center was on vertebral body. 95% of T10 vertebrae and 88% of T11 vertebrae belonged to the "thoracic" type whereas 97% of L1 ans 98% of L2 belonged to the lumbar type. At the T12 level, we found 35% of "thoracic" type and 65% of "lumbar" type. Long MP were found on "lumbar" type vertebrae with little interzygapophyseal angles (p < 0.001). "Anatomical" types were not related to different MP lengths. On the contrary, the "functional" classification showed shorter MP on "thoracic" type vertebrae than on "lumbar" vertebrae (1.9 +/- 2.9 mm vs 4.5 +/- 3 mm, p < 0.03). A large interzygapophyseal angle is known to enhance the axial rotation of the thoraco-lumbar junction. We infer that MP also play a role in axial rotation.(ABSTRACT TRUNCATED AT 250 WORDS)

[Association of infectious aneurysm and microbial spondylodiscitis: physiopathological hypotheses, diagnostic and therapeutic approach].

Two years after a Staphylococcus aureus septicaemia, in a patient with dermatopolymyositis occurred an infectious aneurysm of abdominal aorta with contiguous pyogenic spondylodiscitis. Coexistence of both pathologies is rare and physiopathological mechanisms still remain uncertain. However, many arguments in the present case report are in favour of the initial responsibility of an infectious aneurysm. Main interest in early diagnosing infectious aneurysm, allowed by new investigations such as magnetic resonance imaging and marked leukocyte bone scanning, is the prevention of major complications. Antibiotherapy and surgical removal of infectious aneurysm must be quickly achieved in every case.

[Diffusion of imipenem in synovial fluid].

The diffusion of imipenem (IMP) in the knee joint was studied after a 1 g i.v. administration of Tienam over one hour. The synovial fluid was collected under anesthesia during arthroscopy carried out for mechanical lesions of the knee (meniscal lesions after ligamental injuries or sequelae after meniscectomy), in 3 groups of six patients at one, two, or three hours after the end of injection of IMP. The concentrations of IMP determined by high performance liquid chromatography (HPLC) were: 42.5, 20.1, 9.3 and 5.7 mg/l in the blood at T0, T1, T2 and T3 hr, respectively; 20.4, 13.0 and 7.9 mg/l in the synovial fluid at T1, T2 and T3, respectively. The decrease of IMP concentrations in the synovial fluid was 1,5 times as low as in serum. On account of its broad-spectrum antibacterial activity and our data, IMP could be used in perioperative prophylaxis of the knee joint surgery.
