Long fusion to the sacrum has been demonstrated to increase the mechanical failure rate after adult spinal deformity (ASD) surgery, and these mechanical failures are the most common etiology for reoperation. The purpose of this study was to determine the incidence and risk factors for mechanical failure associated with reoperation after spinal fusion to the sacrum in ASD. ⋯ Overall, 37 % of the patients who underwent ASD surgery involving the sacrum required reoperation for mechanical failure. The most frequent form of mechanical failure associated with reoperation was surgical PJK. Significant risk factors for mechanical failure included medical comorbidities, smoking, and severe preoperative sagittal imbalance. Critical mechanical failure may have a negative influence on health status.

Randomized Controlled Trial
Weight bearing the same day versus non-weight bearing for 4 weeks in Achilles tendon rupture.
Achilles tendon rupture (ATR) often occurs in 40- to 50-year-old men. Multiple studies discuss the correct treatment strategy based on surgical or nonsurgical intervention, including early mobilization. We aimed to compare the outcomes of bearing weight on the same day with non-weight bearing over a 4-week period of ATR patients. ⋯ This study showed that a well-conducted early-weight-bearing treatment has good clinical outcomes, with a complication rate no higher than non-weight-bearing treatment.

Efficacy of tramadol-acetaminophen tablets in low back pain patients with depression.
Tramadol-acetaminophen tablets are currently used to treat pain, including that of degenerative lumbar disease. Although there are many reports on tramadol-acetaminophen tablets, treatment outcomes in low back pain (LBP) patients with depression remain uncertain. This study investigated the outcomes of LBP patients with depression treated with tramadol-acetaminophen tablets. ⋯ This investigation found that tramadol-acetaminophen is effective for reducing LBP and provided a prophylactic antidepressant effect in chronic LBP patients with depression.

Trauma patients have the highest risk of developing venous thromboembolism (VTE) among hospitalised patients, with a reported 13-fold greater risk of developing VTE over non-trauma patients. This study examines the incidence of VTE and associated complications in trauma patients with lower limb fractures or injuries. ⋯ This study found that major trauma patients have an approximate six-fold increased risk of developing VTE during admission compared with minor trauma patients (relative risk: 5.79; 95 % confidence interval: 3.94-8.49). Our findings support the use of extended prophylaxis to treat minor trauma patients.

Observational Study
Japanese orthopaedic association back pain evaluation questionnaire (JOABPEQ) as an outcome measure for patients with low back pain: reference values in healthy volunteers.
In 2007, the Japanese orthopaedic association back pain evaluation questionnaire (JOABPEQ) was established to overcome the limitations of the original JOA scoring system developed in 1986. Although this new self-administered questionnaire is a more accurate outcome measure for evaluating patients with low back pain, physicians were unable to as certain the exact status of a patient at a single time point because of a lack of reference values. This study aimed to establish the reference values of JOABPEQ in different age and gender groups using data obtained from healthy volunteers. ⋯ The reference values for JOABPEQ according to age and gender were established herein. Patients with low back pain should be evaluated with this new self-administered questionnaire taking these reference values into account.
