Influence of equipment choice and athletic experience on the incidence of kitesurfing injuries - A prospective observational study.

Background: Kitesurfing is a popular activity among recreational athletes in Germany, and the number of athletes is constantly increasing. The objective of this study was to examine the influence of athletic experience and equipment choice on the frequency of kitesurfing injuries in Germany.

Methods: Sixty-six athletes completed a standardized questionnaire at the beginning and end of a summer season.

Pullout strength and failure mode of industrially manufactured and self-made all-suture anchors: a biomechanical analysis.

Background: This study presents a new technique for assembling an all-suture anchor from existing medical products. The biomechanical characteristics of this self-made anchor (SMA) are compared with those of an industrially manufactured all-suture anchor.

Methods: The SMAs were made from established medical products (FiberWire #2 and 2-mm FiberTape; Arthrex, Naples, FL, USA).

Treatment of Chronic Acromioclavicular Joint Dislocation in a Paraplegic Patient with the Weaver-Dunn Procedure and a Hook-Plate.

In case of patients with spinal cord injury and concomitant acromioclavicular (AC) joint-dislocation the treatment is challenging, as in this special patient group the function of the shoulder joint is critical because patients depend on the upper limb for mobilization and wheelchair-locomotion. Therefore the goal of this study was to examine, if the treatment of chronic AC-joint dislocation using the Weaver-Dunn procedure augmented with a hook-plate in patients with a spinal cord injury makes early postoperative wheelchair mobilization and the wheelchair transfer with full weight-bearing possible. In this case the Weaver-Dunn procedure with an additive hook-plate was performed in a 34-year-old male patient with a complete paraplegia and a posttraumatic chronic AC-joint dislocation.

[Surgical treatment of 3- and 4-part fractures of the humeral head using a polyaxial-locking plate: results and patient satisfaction].

Introduction: In recent years, new angle-stable plate implants with polyaxial screw direction were developed with the aim of an improved treatment of displaced 3- and 4-part fractures of the proximal humerus. There are only a few studies available about polyaxial implants in the treatment of 3- and 4-part proximal humerus fractures. Therefore, the aim of this study was to evaluate clinical results and complications of open reduction and internal fixation of displaced 3- and 4-part fractures using a polyaxial plate.

[Trampoline-related injuries in children: an increasing problem].

Introduction: The sales of recreational trampolines have increased during the past few years. Severe injuries are associated in part with trampoline sport in the domestic setting. Therefore, this study was conducted to confirm the hypothesis of an increase in trampoline-related injuries in conjunction with the increasing sales of recreational trampolines and to find out what kind of injuries are most frequent in this context.

Traumatic Infra-renal Aortic Dissection After a High-energy Trauma: A Case Report of a Primary Missed Diagnosis.

A traumatic infra-renal aortic dissection is a rare but life-threatening injury that follows deceleration injuries. The mechanism of blunt abdominal aortic injury involves both direct and indirect forces. The successful management of patients with traumatic injuries depends on a prompt suspicion of the injury and early diagnosis and therapy.

Risk factors for heterotopic ossification in patients with spinal cord injury: a case-control study of 264 patients.

Study Design: Case-control study.

Objective: We designed a case-control study to analyze the risk factors associated with the development of heterotopic ossification (HO) in patients with traumatic spinal cord injury.

Summary Of Background Data: Patients with spinal cord injury have a high risk of developing HO, although the exact etiopathogenesis is still unknown.

Regenerate augmentation with bone marrow concentrate after traumatic bone loss.

Distraction osteogenesis after post-traumatic segmental bone loss of the tibia is a complex and time-consuming procedure that is often complicated due to prolonged consolidation or complete insufficiency of the regenerate. The aim of this feasibility study was to investigate the potential of bone marrow aspiration concentrate (BMAC) for percutaneous regenerate augmentation to accelerate bony consolidation of the regenerate. Eight patients (age 22-64) with an average posttraumatic bone defect of 82.

[A new reduction technique for posterior locked shoulder dislocation. Case report and technique description].

The case of a 61-year-old male with posterior dislocation of the right shoulder joint is presented and a new technique for closed reduction of posterior locked shoulder dislocation is described. The technique involves four steps: in step 1 a constant traction is applied on the injured arm, in step 2 the arm is internally rotated and in steps 3 and 4 the second arm of the physician is used as a lever arm to lateralize and ventralize the shoulder. Lateralization and ventralization of the humeral head are essential to engage the humeral head and to pass it around the glenoid during reduction.

Clinical outcome and complications using a polyaxial locking plate in the treatment of displaced proximal humerus fractures. A reliable system?

Introduction: The surgical treatment of displaced proximal humeral fractures (ORIF) is a perpetual challenge to the surgeon. For this reason, the principle of polyaxiality was developed to provide an improved primary stability of the fracture through better anchorage of the screws, especially in osteoporotic bone. The aim of this study was to present clinical results with the polyaxial locking plate in the operative treatment of proximal humerus fractures in order to determine whether the technique of polyaxiality leads to better functional outcome and lower complication rates in comparison to monoaxial plates in the literature.
