Randomized Controlled TrialEfficacy of periarticular multimodal drug injection in total knee arthroplasty. A randomized trial.
Postoperative analgesia with the use of parenteral opioids or epidural analgesia can be associated with troublesome side effects. Good perioperative analgesia facilitates rehabilitation, improves patient satisfaction, and may reduce the hospital stay. We investigated the analgesic effect of locally injected drugs around a total knee prosthesis. ⋯ Intraoperative periarticular injection with multimodal drugs can significantly reduce the requirements for patient-controlled analgesia and improve patient satisfaction, with no apparent risks, following total knee arthroplasty.

Predictors of short-term functional outcome following ankle fracture surgery.
Ankle fractures are among the most common injuries treated by orthopaedic surgeons. However, very few investigators have examined the functional recovery following ankle fracture surgery and, to our knowledge, none have analyzed factors that may predict functional recovery. In this study, we evaluated predictors of short-term functional outcome following surgical stabilization of ankle fractures. ⋯ One year after ankle fracture surgery, patients are generally doing well, with most experiencing little or mild pain and few restrictions in functional activities. They have a significant improvement in function compared with six months after the surgery. Younger age, male sex, absence of diabetes, and a lower ASA class are predictive of functional recovery at one year following ankle fracture surgery. It is important to counsel patients and their families regarding the expected functional recovery after an ankle injury.

Treatment of multidirectionally unstable supracondylar humeral fractures in children. A modified Gartland type-IV fracture.
There is an uncommon subset of supracondylar humeral fractures in children that are so unstable they can displace into both flexion and extension. The purposes of this study were to describe this subset of supracondylar fractures and to report a new technique of closed reduction and percutaneous pinning for their treatment. ⋯ In rare supracondylar fractures in children, multidirectional instability results in displacement into flexion and/or extension. This fracture can be classified as type IV according to the Gartland system, as it is less stable than a Gartland type-III extension supracondylar fracture. These fractures can be treated successfully with a new technique of closed reduction and percutaneous pinning, thus avoiding open reduction.

A single lumbar hemivertebra can be expected to cause progressive scoliosis. The aim of this study was to evaluate the results of a lumbar hemivertebra resection and short-segment fusion through a combined posterior and anterior approach. ⋯ Excision of a lumbar hemivertebra is safe and provides stable correction when combined with a short-segment fusion. Surgery should be performed as early as possible to avert the development of severe local deformities and prevent secondary structural deformities that would require a more extensive fusion later.

The functional outcome following ankle fractures that involve a posterior malleolar fragment is often not satisfactory, and treatment of this type of fracture remains controversial. Thorough knowledge of the pathologic anatomy of the posterior malleolar fracture is essential for planning appropriate treatment. Thus, we conducted a computed tomographic study to clarify the pathologic anatomy of the posterior malleolar fracture. ⋯ The fracture lines associated with posterior malleolar fractures appear to be highly variable. A large fragment extending to the medial malleolus existed in almost 20% of the posterior malleolar fractures in the current study, and some fragments involved almost the entire medial malleolus. Because of the great variation in fracture configurations, preoperative use of computed tomography may be justified. The information obtained from this study will be helpful for conducting basic research of this condition and for determining appropriate surgical approaches.
