ABSTRACT

Background: Tibial plateau leveling osteotomy (TPLO) and cranial closing wedge ostectomy (CCWO) are common treatments for cranial cruciate ligament disease. These two techniques mainly differ in whether the proximal tibial fragment contains the attachment site of the patellar ligament. Currently, no reports compare how these techniques affect the patellofemoral joint. Aim: This ex vivo study aimed to compare the effects of TPLO and CCWO on the patellar position and moment arm in healthy Beagles. Methods: TPLO and CCWO were performed on each stifle in six cadavers of Beagles. Pre- and postoperative mediolateral radiographs with the stifle angle at approximately 90° were obtained. The modified Blumensaat index (MBI), patellar ligament length to patella length ratio (PLL:PL), and patellar moment arm (PMA) were measured in each radiograph. Mixed-model multiple regression analyses for the MBI, PLL:PL, and PMA, with the surgical procedure as the independent variable, were then performed. The joint angle was included as an independent variable for MBI and PMA. Results: The PLL:PL was decreased after TPLO. Additionally, the PLL:PL after TPLO was significantly lower than that after CCWO. The MBI decreased with flexion. Postoperative MBI values were reduced for both procedures, with lower values after CCWO than after TPLO. The PMA values decreased with flexion. Postoperative values for both methods were reduced in the PMA, with the values being lower after CCWO than after TPLO. Conclusion: Both TPLO and CCWO affect the patellofemoral joint. Compared with TPLO, CCWO produced more excellent downward traction on the patella. Therefore, CCWO may be used to correct the patellar alta and treat cranial cruciate ligament disease.

ABSTRACT

A 47-year-old man was found at his home in a state of cardiopulmonary arrest. His family performed cardiopulmonary resuscitation on him. He was brought to our hospital by ambulance. On arrival, his pupils were dilated and his heart was in a state of ventricular fibrillation. After returning to spontaneous circulation by the cardiopulmonary resuscitation, the electrocardiogram revealed ST elevation at V2-V5. Cardiac catheterizatin revealed a left anterior descending coronary obstruction. Percutaneous coronary angioplasty was performed. On the 26th day after admission, acalculous cholecystitis was found. It was difficult to perform emergent surgery, because the patient was taking an anticoagulant drug. We performed PTGBA (percutaneous transhepatic gallbladder aspiration) on the same day, and the gallbladder inflammation was improved. We consider that PTGBA is an effective treatment for difficult cases of acalcuous cholecystitis.

ABSTRACT

A 54 year old man was brought to our hospital by ambulance. He had been injured by falling heavy steel. An examination was performed, and he was diag nosed as having sinking skull, acute extradural hematoma, trauma of the righ eye, right eye laceration, injury of the optic canal (right blind), and multipl fractures. Open fractures were observed in the right ring finger and little finger Simple fractures were observed in the zygomatic bone nasal bone and maxillary bone. An emergency operation (external skeletal fixation, taxis of the skull and maxillary bone, extradural hematoma depletion, suture of right eyelid) was performed. His life was saved by consistent team treatment from preoperation t postoperation. He was discharged from our hospital on foot at 45 days after th operation.
