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.

Comparative Study Clinical TrialDoes laminoplasty really improve neurological status in patients with cervical spinal cord injury without bone and disc injury? A prospective study about neurological recovery and early complications.
Cervical spinal cord injury without bone and disc injury in patients with spinal cord compression is a fairly common problem in Japan. Because elderly Japanese population tend to have cervical spinal canal stenosis. However, there has been no consensus in the treatment of these patients. We conducted a prospective study to evaluate treatment outcomes and complications of these patients. ⋯ In the present study, we found no significant difference in paralysis improvement between surgical and conservative treatment, although we observed a higher frequency of complications with surgery.

The pattern of acute injuries in patients from alpine skiing accidents has changed during 2000-2011: analysis of clinical and radiological data at a level I trauma center.
During the last decade, many educational efforts and technological improvements have been made to protect skiing athletes from injuries. Whether these efforts have changed the pattern of acute injuries from skiing casualties has not yet been shown on a medical basis, which this longitudinal study examines. ⋯ Acute radiological evaluation in skiing accidents has changed during the last decade. The decrease in overall cerebral injuries might be a function of the increasing use of skiing helmets. A protection of the extremities, trunk, spine, and face, however, needs further improvements and their radiological assessment with CT warrants attention in skiing casualties.

Long-term survival of GSB III elbow prostheses and risk factors for revisions.
Although replacement of the elbow joint is a complex procedure there is not much clinical evidence that contributes to surgical decision-making, mainly due to small clinical samples and short follow-up. Therefore, we performed a long-term analysis up to 30 years after implantation of a GSB III total elbow prosthesis to quantify long-term outcome and to identify possible risk factors for implant revision. ⋯ The results indicate a good long-term prognosis for this design. The prognosis has to be adjusted for the underlying disease. Previous operations such as joint reconstruction significantly increase the risk of revision.

Evaluation of reduction and fixation of calcaneal fractures: a Delphi consensus.
Postoperative radiological assessment of the quality of reduction and fixation of calcaneal fractures is essential when evaluating treatment success. However, a universally accepted radiological evaluation protocol is currently unavailable. The aim of this study was to obtain an expert-based consensus on the most important criteria for the radiological assessment of the quality of reduction and fixation of calcaneal fractures. ⋯ This Delphi consensus shows that more aspects require evaluation than currently used in radiological evaluation protocols. With this consensus, we provide the basis for a universal evaluation protocol to assess the radiological outcome of calcaneal fracture treatment.
