Poor osteochondral repair by a biomimetic collagen scaffold: 1- to 3-year clinical and radiological follow-up.

Introduction: Treatment of osteochondral injuries is challenging, and no gold standard has been established. Layered cell-free scaffolds are a new treatment option for these defects. The aim of this study was to evaluate the osteochondral repair in patients treated with the MaioRegen(®) scaffold, a cell-free biomimetic scaffold consisting of type I collagen and hydroxyapatite.

Bone properties of the humeral head and resistance to screw cutout.

Unlabelled: Surgical treatment of fractures involving the proximal humeral head is hampered by complications. Screw cutout is the major pitfall seen in connection with rigid plating. We have exploited a bony explanation for this phenomenon.

[The effect of geriatric intervention on rehabilitation of elderly patients with hip fracture].

Introduction: Hip fracture is the most common cause of long hospitalisation among elderly and is increasing in the group of elderly aged 85+ years. Hip fractures are associated with a host of factors and mainly caused by falls and osteoporosis.

Material And Methods: The Geriatric Team of the orthopaedic ward, geriatric rehabilitation and follow-home function (GO) is compared to traditional orthopaedic treatment (ORT) among elderly aged 65+ with respect to: haemoglobin difference before surgery and 3-6 months after fracture, osteoporosis treatment, length of stay, change in accommodation, readmission and mortality within six months after admission and incidence of new fracture within two years.

The outcome of arthroscopic and open surgery ankle arthrodesis: a comparative retrospective study on 107 patients.

Purpose: To evaluate the results of arthroscopic guided ankle arthrodesis, and the results of open surgery arthrodesis in two comparable groups of patients.

Methods: A group of 58 arthroscopic guided ankle arthrodeses was compared to a group of 49 ankles arthrodeses operated by open technique. The patients and ankles in both groups fulfilled the same criteria of inclusion except that the ankles operated by open technique had a varus/valgus malalignment exceeding 5 degrees.

Stability of a cannulated screw versus a Kirschner wire for the proximal crescentic osteotomy of the first metatarsal: a biomechanical study.

The purpose of this study was to compare the stability of a Kirschner wire (K-wire) versus a single cannulated screw for fixation of the proximal crescentic first metatarsal osteotomy. Seven matched pairs of fresh-frozen human cadaver first metatarsal specimens were dissected out en bloc at the first metatarsal-medial cuneiform complex; right and left specimens were randomized as to fixation. In screw specimens, a cannulated screw was mounted from the proximal medial side of the metatarsal, traversing osteotomy and engaging the lateral diaphyseal cortical bone.

[Measuring of preoperative anxiety by three self-reporting scales: State Trait Anxiety Inventory, Symptoms CheckList 92 and visual analogue scale].

Introduction: Preoperative anxiety is a common phenomenon. It is therefore necessary to investigate whether quantitative self-reporting anxiety scales can be helpful in the anaesthetic clinic and research. The aim of this study was to compare the state trait anxiety inventory (STAI), symptoms checklist 92 (SCL 92), the subscales anxiety and phobic anxiety, and a visual analogue scale for anxiety (VAS).
