Objectives: Standard guidelines regarding the management of un-displaced LC-1 type pelvic ring injury supported by data in literature are lacking, though it is considered to be stable and widely managed nonoperatively. In our study we evaluated the functional outcome of LC-1 pelvic ring injury with incomplete sacral fracture managed non-operatively in patients having age more than 18 years and minimum follow-up of 6 months. Methods: 46 patients having LC-1 pelvic ring injury with incomplete sacral fractures having age more than 18 years and minimum follow-up of 6 months were identified from the hospital record. All these patients were managed with non-weight bearing walking for first 3 weeks followed by weight bearing as tolerated. Patients were called in outpatient department for final evaluation of functional outcome measured according to Majeed score. Results: Mean Majeed score was 82.59 ± 6.77 (excellent in 27 patients and good in 19 patients). 8 patients had fractures in addition to pelvic ring injury and 3 patients had abdominal injuries (3 excellent, 8 good). 11 patients had follow-up less than 12 months (mean Majeed score 84.36 ± 5.75; 8 excellent, 3 good) and 35 patients had follow-up more than 12 months (mean Majeed score 82.03 ± 7.04; 19 excellent, 16 good). There was no mortality in any group. Conclusion: LC-1pelvic ring injury with incomplete sacrum fracture can be managed non-operatively with non-weight bearing walking for first 3 weeks followed by weight bearing as tolerated with excellent or good functional outcome. The best functional outcome for a patient is achieved within 12 months and does not change after that period. Also being a low energy trauma this injury has low mortality rate.
Horizontal intra-articular dislocation of the patella is a very rare traumatic entity. We present an unusual case of horizontal intra-articular dislocation in which the patellar articular surface was facing upwards besides having an avulsion of the quadriceps tendon from the superior pole. There was associated posterolateral knee subluxation, which has not been described with intra-articular dislocation of the patella. A 20-year-old man presented with open patellar dislocation and locked knee after a roadside accident. The patient was managed successfully by open reduction and repair of the quadriceps tendon. There was buttonholing of the medial femoral condyle through the medial retinaculum leading to irreducible dislocation. A special reduction manoeuvre was employed to bring the knee to its normal alignment. Knowledge of this injury pattern is of utmost importance for proper recognition and appropriate allocation of the surgical technique.
Lumbar artery pseudoaneurysms following blunt trauma are very rare. We report a case of polytrauma patient having lumbar spine injury and pelvic fracture presenting with hemodynamic instability. The patient did not improve after aggressive resuscitation. There was no evidence of intraabdominal solid organ or visceral injury. We suspected injury to pelvic vessels as a source of bleeding. Computed tomography (CT) angiography was done. A small size (6 × 5 mm) lobulated hyperdense structure is seen in the territory of a left 4th lumbar branch of aorta suggestive of a pseudoaneurysm. Whenever there is a patient of blunt abdominal trauma with pelvic or spine injury and source of bleeding cannot be established, lumbar vessels as a source of bleeding should be kept in mind. CT angiography must be done for diagnosis and patient may subsequently need angioembolization of these vessels.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
