Grip strength during short and sustained maximal voluntary isometric contractions was measured in 28 females and 5 males with displaced Colles' fracture involving the distal radio-ulnar joint. The patients were randomized into two groups, treated either through immobilization with plaster cast or with external fixation. The recovery of isometric grip strength was followed over a two-year period...
Neglected posterior dislocation of the elbow is a common problem in developing countries. One acceptable form of treatment is open reduction and transarticular Steinmann pin fixation. However, this leads to a stable but stiff elbow. We used an improvised external fixator after open reduction in two cases, which allowed for early mobilisation with adequate stability. This option can be considere...
Distraction osteogenesis has been used for more than 50 years to address limb-length discrepancy and deformity. Intramedullary fixation has been used in conjunction with external fixation to decrease the time in the external fixator and prevent deformity and refracture. A new generation of motorized intramedullary nails is now available to treat limb-length discrepancy and deformity. These nail...
Femoral neck fractures in young patients are usually caused by a high-energy trauma, which results in a perpendicular fracture. Although efforts are focused on preserving the femoral head in young patients, vertical femoral neck fracture is a problematic orthopedic injury due to the domination of shear forces. Due to controversy regarding which fixation method is the best choice, the purpose of...
PURPOSE To assess the efficacy of acute invaginating docking for infected non-unions of the humerus. METHODS Eight men and 3 women aged 17 to 59 years with infected non-unions of the humerus underwent acute invaginating docking with shortening and Ilizarov fixation. RESULTS The mean shortening was 2.9 cm owing to additional debridement. The mean time to external fixator removal was 14.9 (ra...
Purpose. Comparison of monoaxial and polyaxial screws with the use of subcutaneous anterior pelvic fixation. Methods. Four different groups each having 5 constructs were tested in distraction within the elastic range. Once that was completed, 3 components were tested in torsion within the elastic range, 2 to torsional failure and 3 in distraction until failure. Results. The pedicle screw system...
Authors report the results they obtained when the Ilizarov circular external fixator was used for the treatment of post-traumatic nonunion of the tibia. A total of 20 patients were treated. Of these 12 had been submitted to treatment elsewhere and using other methods; 9 presented with septic nonunion; 10 revealed radiographic findings of atrophic nonunion, and 10 were hypertrophic. There was ax...
This article presents the validation of a technique to assess the appropriateness of a 2 degree-of-freedom model for the human knee, and, in which case, the dominant axes of flexion/extension and internal/external longitudinal rotation are estimated. The technique relies on the use of an instrumented spatial linkage for the accurate detection of passive knee kinematics, and it is based on the a...
OBJECTIVE To review external fixation in the management of war injuries. METHOD We prospectively followed up 15 external fixators (14 patients) applied in the management of war injuries. All these patients were treated at 202 Field Hospital during the 2003 Gulf Conflict. RESULTS Of the 15 fixators, 13 (86.7%) required early revision or removal due to complications of the injury or the fixat...
In the literature, we can find many articles that describe in detail specific complex procedures related to the limb reconstruction. However, the general information on the biological and mechanical bases of callotasis is out of date, and the surgeons must relate to works dating from the early 1980s. These articles also come from a period in which the callotasis technique was being developed an...
