ABSTRACT
The incidence of postoperative ileus (POI) after colonic and abdominal surgery is high. On the other hand, the reported incidence after lower extremity reconstruction ranges from 0.3% to 4.0%. This paper reports an 81-year-old woman who expired due to POI at six days after primary total knee arthroplasty. The risk factors, diagnosis, preventive methods, and treatment of POI were also investigated through literature reviews.
ABSTRACT
Purpose@#This study evaluated the medial joint stability after high tibial osteotomy (HTO) releasing the superficial medial collateral ligament (sMCL) without cutting and repairing. @*Methods@#Twenty-one patients who performed HTO were enrolled. After an L-shaped incision was made in the pes anserinus, the sMCL was released from the distal portion during surgery. After plate fixation, the sMCL was reattached and the pes anserinus was repaired underneath the plate. Plate removal was performed after 31.1 ± 14.2 months. Before HTO, a valgus force of 40 N was exerted at extension for reference values. Before and after plate removal, a valgus force of 40 N was exerted at extension and at a flexion position of 20°. Medial stability was evaluated by measuring the joint line convergence angle (JLCA). @*Results@#The JLCAs in the extension state before HTO and plate removal were 1.64° ± 1.15° and 1.83° ± 1.36°, respectively; there was no significant difference (p = 0.198). There was also no significant difference in JLCA before HTO and after plate removal (p = 0.835). There was also no significant difference in JLCA before and after plate removal both at a knee extension and flexion position of 20° (p = 0.348 and p = 0.456, respectively). @*Conclusions@#Releasing the sMCL without cutting and repairing the pes anserinus underneath the plate during medial open wedge HTO could facilitate the maintenance of medial joint stability.

ABSTRACT
In accordance with extending survival periods of cancer patients, number of consecutively developing metastatic spinal tumor is also increasing. There have been improvements in the treatment results of metastatic spine tumor by virtue of the developments in diagnostic radiology, chemotherapy, adjuvant treatment, operative device and technique, discrete preoperative plan, and standardized operation. Accordingly, surgical indication has also increased. Clinically, in case of metastatic spine tumor, treatment of tumor itself should be focused on pain relief, preservation of neurologic function, prevention of pathologic fracture, prevention of pathologic fracture, and correction of spinal instability for improving quality of life, rather than for extension of survival. Additionally, etiology of spinal tumor, correct diagnosis and subsequent treatment principles should be thoroughly understood before establishing treatment plans for effective treatments.
