How does spinal canal decompression and dorsal stabilization affect segmental mobility? A biomechanical study
Thu, 19 Nov 2009 20:00:43 -0000
Abstract Introduction When decompression of the lumbar spinal canal is performed, segmental stability might be affected. Exactly which anatomical structures can thereby be resected without interfering with stability, and when, respectively how, additional stabilization is essential, has not been adequately investigated so far. The present investigation describes kinetic changes in a surgically treated motion segment as well as in its adjacent segments. Material and methods Segmental biomechanical examination of nine human lumbar cadaver spines (L1 to L5) was performed without preload in a spine-testing apparatus by means of a precise, ultrasound-guided measuring system. Thus, samples consisting of four free motion segments were made available. Besides measurements in the native (untreated) spine specimen further measurements were done after progressive resection of dorsal elements like lig. flavum, hemilaminectomy, laminectomy and facetectomy. The segment was then stabilised by means of a rigid system (ART®) and by means of a dynamic, transpedicularly fixed system (Dynesys®). Results For the analysis, range of motion (ROM) values and separately viewed data of the respective direction of motion were considered in equal measure. A very high reproducibility of the individual measurements could be verified. In the sagittal and frontal plane, flavectomy and hemilaminectomy did not achieve any relevant change in the ROM in both directions. This applies to the segment operated on as well as to the adjacent segments examined. Resection of the facet likewise does not lead to any distinct increase of mobility in the operated segment as far as flexion and right/left bending is concerned. In extension a striking increase in mobility of more than 1° compared to the native value can be perceived in the operated segment. Stabilization with the rigid and dynamic system effect an almost equal reduction of flexion/extension and right/left bending. In the adjacent segments, a slightly higher mobility is to be noted for rigid stabilization than for dynamic stabilisation. A linear regression analysis shows that in flexion/extension monosegmental rigid stabilisation is compensated predominantly in the first cranial adjacent segment. In case of a dynamic stabilisation the compensation is distributed among the first and second cranial, and by 20% in the caudal adjacent segment. Summary Monosegmental decompression of the lumbar spinal canal does not essentially destabilise the motion segment during in vitro conditions. Regarding rigid or dynamic stabilisation, the ROM does not differ within the operated segment, but the distribution of the compensatory movement is different.

Acute non-displaced fractures of the scaphoid: earlier return to activities after operative treatment. A controlled multicenter cohort study
Wed, 18 Nov 2009 00:07:48 -0000
Abstract Introduction To investigate whether operative treatment leads to earlier return to previous activity level, 94 patients with the same number of isolated, acute, complete, stable and non-displaced fractures of the scaphoid mid-third were involved in a prospective, multicenter cohort study. Method Fractures were either fixed with a cannulated screw or immobilized with a short arm cast, and followed for 6 months. Results By 15 weeks, patients receiving surgical treatment returned significantly earlier to their full time work and home activities, as well as achieved significantly better results for functional status, pain, and overall satisfaction. However, complication rates concerning union and secondary operative management were higher. Conclusion Operative treatment therefore primarily facilitates earlier return to previous activity level, as well as better functional status, less pain and higher patient satisfaction, yet conservative treatment seems to be safer and associated with a lower complication rate.

Fracture of the tibial bone block after posterior cruciate ligament allograft reconstruction using double cross pins

Abstract We report the fracture of the tibial bone block after posterior cruciate ligament reconstruction using double cross pins for bone block fixation in the postoperative period. The possible reasons include the size of bone block, direction of cross pin or the quality of bone block. This case emphasizes the biomechanical properties and failure of modes of double cross pin.

Passive navigation principle for orthopedic interventions with MR fluoroscopy
Wed, 18 Nov 2009 00:07:47 -0000
Abstract Introduction Of late, computer-assisted surgery has become a novel challenge for orthopedic surgeons. However, for orthopedic interventions magnetic resonance (MR) fluoroscopy is in its early stages of development. The authors have developed an innovative passive navigation concept, which is potentially applicable for many magnetic resonance image (MRI)-guided musculoskeletal interventions. With this method, no switching between different planes is required, since the cross-sectional modality of the MRI is used as a new navigation approach. Materials and methods This method was mainly evaluated in retrograde drilling of artificial osteochondral lesions of the talus as an example of difficult navigation in drill placement due to poor visualization with X-ray and complex anatomy. To accomplish this objective, a passive navigation device was constructed and evaluated in nine cadaveric ankle joint specimens. Feasibility and accuracy of navigated drillings were evaluated. Results The interactive high-field MR fluoroscopy and the passive aiming device allow precise drilling of osteochondral lesions of the talus, despite the complex anatomy of the ankle. Drillings could be performed with an accuracy of 1.6 mm. The drilling guide was safe and easy to handle. Conclusion The MR-assisted retrograde drilling of osteochondral lesions may enable precise and safe treatment without radiation exposure. This passive navigation technique for MR fluoroscopy is potentially applicable for many orthopedic interventions and may present an alternative to other navigation methods. Especially, the treatment of pediatric and adolescent patients may benefit from the typical MRI properties.

Diagnostic imaging and unforeseen associated lesions in astragalo-scaphoid dislocation: a case report
Wed, 18 Nov 2009 00:07:47 -0000
Abstract A case of an isolated astragalo-scaphoid dislocation following a fall from a motorbike is reported. Due to the diagnostic obscurity of the full extent of the injury, computed tomography (CT) with 3D reconstruction was utilized to precisely visualize the articular condition and revealed the presence of small intra-articular bone fragments and calcaneo-cuboid subluxation. Furthermore, the detailed imaging offered valuable information for preoperative planning. Patient has healed without sequelae. In light of the good outcome in this case, we suggest utilizing CT with 3D reconstruction when there is a risk to overlook foot dislocation and potential associated lesions.
