Surgical approach and prosthesis fixation in hip arthroplasty world wide.
Hip arthroplasty is one of the most common and successful surgical procedures worldwide. Component design and materials as well as surgical techniques constantly evolve. There is no consensus among surgeons regarding the ideal surgical approach and method of fixation. ⋯ The most common surgical approaches in use in hip arthroplasty are posterior and lateral. Anterior approach is used by a minority of orthopedic surgeons for that purpose. Cementing hip prosthesis is falling out of favor among orthopedic surgeons worldwide. The trend toward un-cemented hip arthroplasty is not well supported in the current literature.

Incidental dural tear in lumbar spinal decompression and discectomy: analysis of a nationwide database.
An incidental dural tear (DT) is one of the most common intraoperative complications in lumbar spine surgery. The purpose of this study was to report the incidence of DT in lumbar spinal decompression (LSD) and lumbar discectomy (LD), risk factors, and patient outcomes on a national level. ⋯ The incidence of DT was higher in LSD (6.3 %) than in LD (1.9 %), based on a national database. The effect of DT on in-hospital morbidity and mortality and health care burdens was more significant in LSD than in LD.

Weak link of tendon-bone healing and a control experiment to promote healing.
This study aims to observe the mechanical weak point and histological features of tendon-bone interface after anterior cruciate ligament reconstructive surgery and to explore the tendon-bone healing effects of the platelet-rich gel (PRG) + deproteinized bone (DPB) compound. ⋯ The mechanical weak point of the early tendon-bone interface was in the immature fibrous tissue. The PRG + DPB compound can effectively trigger tendon-bone healing by promoting the maturation and ossification of the tendon-bone tissue. This compound improved the tensile strength of the healing interface and reduced bone tunnel enlargement.

Multicenter Study Clinical TrialGlenoid morphology affects the incidence of radiolucent lines around cemented pegged polyethylene glenoid components.
Radiolucent lines (RLL) are frequent findings around cemented all-polyethylene glenoid implants. The present study evaluates the frequency, extend and the clinical impact of RLL around a cemented two-pegged glenoid implant with special focus on the influence of preoperative glenoid morphology. Our hypothesis was that glenoid morphology does not affect clinical outcome and RLL in the investigated setting. ⋯ Level IV case series study.

Comparative Study Clinical TrialArthroscopically assisted stabilization of acute high-grade acromioclavicular joint separations in a coracoclavicular Double-TightRope technique: V-shaped versus parallel drill hole orientation.
The arthroscopically assisted Double-TightRope technique has recently been reported to yield good to excellent clinical results in the treatment of acute, high-grade acromioclavicular dislocation. However, the orientation of the transclavicular-transcoracoidal drill holes remains a matter of debate. ⋯ The Double-TightRope technique yields good to excellent clinical results in both V-shaped and parallel drill hole placement. Partial recurrent vertical and horizontal instability represents a problem in both techniques. So far, no significant differences regarding clinical or radiologic results have been found. Long-term results are needed to reveal possible advantages in terms of clinical and radiologic acromioclavicular stability.
