Need for Bone Grafts in the Surgical Treatment of Displaced Intra-Articular Calcaneal Fractures

Abstract Controversy is ongoing regarding the use of bone grafts to fill cavities that occur with collapse of the posterior facet in the joint and for repair of the calcaneal height with plating. The present study included 40 patients with 43 displaced intra‐articular calcaneal fractures treated with open reduction and internal fixation from March 2009 to November 2013. In the present case‐control study, the patients were separated into 2 groups: group A received an allograft (20 patients, 22 calcaneal fractures) and group B did not (20 patients, 21 calcaneal fractures). The calcaneal height and Böhlers angle were compared between the 2 groups. The final outcomes for all patients were evaluated using the American Orthopaedic Foot and Ankle Society (AOFAS) ankle hindfoot scale score and compared between the 2 groups. No significant differences were observed between the groups with regard to the basic demographic variables (p > .05). Using Sanders classification, 8 (18%) were type 2, 19 (44%) were type 3, and 16 (37%) were type 4 fractures. The comparisons between the 2 groups showed a loss of Böhlers angle and loss of calcaneal height that was significantly greater in group B (p < .001). No significant differences were observed between the 2 groups in the AOFAS ankle hindfoot scale scores (p > .05). In conclusion, although no differences were found in the clinical results between the 2 groups, more satisfactory radiologic results were obtained in group A, in which bone grafts were used. &NA; Level of Clinical Evidence: 3

Atypical Presentation of an Epidural Hematoma in a Patient Receiving Rivaroxaban After Total Hip Arthroplasty

The authors report a case of a 69-year-old woman who presented with a spontaneous spinal epidural hematoma (SSEH) 10 days after a total hip arthroplasty. The patient had been receiving 10 mg/d of rivaroxaban for 5 days for venous thromboembolism prophylaxis. She had a sudden onset of severe neck pain, followed by quadriplegia below C4. A dorsal SSEH was revealed by computed tomography. While preparing for the emergency evacuation of the SSEH, the neurological symptoms resolved spontaneously in 4 hours. The 1-month follow-up magnetic resonance imaging confirmed that the SSEH had completely resolved. The pathogenesis of SSEH is unclear, but anticoagulant therapy is a known risk factor. It is a relatively rare disorder. Only 1 case of SSEH has been reported, and that patient was receiving a nonsteroidal anti-inflammatory drug besides rivaroxaban, which is another known risk factor for bleeding disorders.

Comparison of Anteromedial and Transtibial ACL Reconstruction Using Expandable Fixation

The influence of anatomical or nonanatomical femoral tunnel position on tunnel widening and clinical outcomes in patients undergoing anterior cruciate ligament (ACL) reconstruction is not fully understood. This retrospective study examined the influence of tunnel width and placement on anterior knee stability and clinical outcomes after ACL reconstruction using the AperFix System (Cayenne Medical Inc, Scottsdale, Arizona), a direct expandable fixation technique with autologous hamstring grafts. The records of 80 patients (79 men and 1 woman) who underwent ACL reconstruction were evaluated. In 38 patients, anatomical femoral tunnel placement was performed via an accessory medial portal (anteromedial group); in the remaining 42 patients, the femoral tunnel was positioned nonanatomically using a transtibial technique (transtibial group). Mean follow-up was 40.7 months (range, 27-60 months). Postoperative knee kinetics were measured, and clinical outcomes were assessed using International Knee Documentation Committee, Lysholm, and Tegner scores. Femoral tunnel widening was measured by comparing postoperative radiographs with final follow-up radiographs. Femoral tunnel width was significantly greater (P<.001) and anterior knee translation was significantly higher (P=.01) in the transtibial group. Lysholm and Tegner scores were not significantly different (P>.05) between the 2 groups. These findings suggest that femoral tunnel widening is associated with increased anterior joint laxity when a direct fixation technique is used for ACL reconstruction, particularly in nonanatomically positioned femoral tunnels. Anatomical femoral tunnel placement provides better anterior stability and less tunnel widening than transtibial tunnel placement; however, these benefits did not produce a detectable advantage in clinical outcomes measures.

Review of management of unstable elbow fractures

Stable and painless elbow motion is essential for activities of daily living. The elbow joint is the second most commonly dislocated joint in adults. The goals of treatment are to perform a stable fixation of all fractures, to achieve concentric and stable reduction of the elbow and to provide early motion. The treatment modality for complex elbow instability is almost always surgical. The treatment objectives are anatomic reduction, stable fixation, and early rehabilitation of the elbow. The common complications of these unstable fractures include recurrent instability, stiffness, myositis ossifications, heterotopic calcification, and neurovascular dysfunction. We analyzed the management of complex elbow fractures and instabilities on the basis of recent literature and suggested possible guidelines for the treatment in this paper. In conclusion, recognition of the injury pattern and restoration of the joint stability are the prerequisites for any successful treatment of an unstable elbow injury.

Súbita perda sensitiva e motora devido a hematoma retroperitoneal durante os períodos de pós‐operatório: relato de caso ☆

A 68 year-old male patient was hospitalized for radical prostatectomy. He had no abnormal medical history including neurological deficit before the operation. Prior to general anesthesia, an epidural catheter was inserted in the L3-4 interspace for intraoperative and postoperative analgesia. After surgery for nine hours, he developed confusion and flaccid paralysis of bilateral lower extremities occurred. No pathology was detected from cranial computed tomography and diffusion magnetic resonance imaging no pathology was detected. His thoracic/lumbar magnetic resonance imaging. Intraabdominal pressure was shown to be 25mmHg, and abdominal ultrasonography revealed progression in the inflammation/edema/hematoma in the perirenal region. The Bromage score was back to 1 in the right foot on the 24th hour and in the left foot on the 26th hour. Paraplegia developed in patients after epidural infusion might be caused by potentiated local anesthetic effect due to retroperitoneal hematoma and/or elevated intra-abdominal pressure.
