Identification of overlengthening after replacement of the radial head with a bipolar prosthesis.

Introduction: Overlengthening of the radial column leads to insufficient functionality and increased capitellar wear. Methods to detect or prevent overlengthening have been described for monopolar prostheses. The aim of this study was to evaluate whether one such method described by Athwal et al.

The circumferential graft technique for treatment of multidirectional elbow instability: a comparative biomechanical evaluation.

Background: Ligament reconstruction with a circumferential graft represents an innovative technique for treatment of multidirectional elbow instability. This biomechanical study compared the stability of the intact elbow joint with the circumferential graft technique and the conventional technique.

Methods: Seven fresh frozen cadaveric elbows were evaluated for stability against valgus and varus/posterolateral rotatory forces (3 Nm) over the full range of motion.

From radial head to radiocapitellar to total elbow replacement: A case report.

Introduction: Radiocapitellar arthroplasty represents a possible treatment option for isolated osteoarthritis of the radial column. We report the first case of early failure of this procedure.

Presentation Of Case: We present the case of a 41-year old male who sustained a terrible triad injury to his right elbow and subsequently underwent radial head arthroplasty.

Peri-implant failure in dual plating of the distal humerus-A biomechanical analysis with regard to screw and plate positioning.

Purpose: The aim of this biomechanical study was to analyse the influence of plate and screw positioning on peri-implant failure in dual plate osteosynthesis. We hypothesized that screw positioning rather than plate configuration influences the risk of peri-implant fractures.

Methods: Twenty macerated humerus specimens were available.

Radial nerve location at the posterior aspect of the humerus: an anatomic study of 100 specimens.

Purpose: Radial neuropathy represents a devastating complication in a posterior approach to the distal humerus. This study aimed to propose "safe zones" regarding the radial nerve (RN) location at the posterior aspect of the humerus to minimize the risk of iatrogenic injury.

Methods: In 100 embalmed specimens, the distances of the proximal edge of the olecranon fossa (OF) to the radial nerve at the medial edge (R1), at the center (R2) and at the lateral edge (R3) of the posterior aspect of humeral shaft were measured.

Elbow Positioning and Joint Insufflation Substantially Influence Median and Radial Nerve Locations.

Background: The median and radial nerves are at risk of iatrogenic injury when performing arthroscopic arthrolysis with anterior capsulectomy. Although prior anatomic studies have identified the position of these nerves, little is known about how elbow positioning and joint insufflation might influence nerve locations.

Questions/purposes: In a cadaver model, we sought to determine whether (1) the locations of the median and radial nerves change with variation of elbow positioning; and whether (2) flexion and joint insufflation increase the distance of the median and radial nerves to osseous landmarks after correcting for differences in size of the cadaveric specimens.

Reliability of Magnetic Resonance Imaging Signs of Posterolateral Rotatory Instability of the Elbow.

Purpose: To evaluate radiographic signs of posterolateral rotatory instability (PLRI) on magnetic resonance imaging (MRI). The goal was to establish objective radiographic criteria to aid in the diagnosis of PLRI.

Methods: The MRI scans of 60 patients were evaluated retrospectively.

The course of the median and radial nerve across the elbow: an anatomic study.

Introduction: Nerve transection has been described as complication of arthroscopic elbow arthrolysis. Therefore, the goal of this study was to define bony landmarks for intraoperative orientation regarding the location of the median and radial nerve.

Methods: In 22 formalin-fixated upper extremities, the radial and median nerves were dissected and marked with respect to their native course.

Reconstruction of the lateral ulnar collateral ligament of the elbow: a comparative biomechanical study.

Purpose: Posterolateral rotatory instability (PLRI) of the elbow is the result of an insufficient lateral collateral ligament complex (LCLC). Single-bundle reconstruction of the lateral ulnar collateral ligament (LUCL) represents the standard treatment method for chronic PLRI. However, cases of recurrent instability after LUCL reconstruction have been reported.

Peripartum pubic symphysis separation--Current strategies in diagnosis and therapy and presentation of two cases.

Background: During spontaneous vaginal delivery, pubic symphyseal widening is normal. Common changes are reversible after complication-free birth. However, cases of peripartum symphysis separation are rare.

Arthroscopic treatment of bilateral snapping scapula syndrome: a case report and review of the literature.

Snapping scapula syndrome represents a rare entity in shoulder surgery. Clinically, it presents as shoulder pain and loud crepitus during shoulder movement. Moreover, glenohumeral bursitis can cause additional pain.

The course of the posterior interosseous nerve in relation to the proximal radius: is there a reliable landmark?

Purpose: The posterior interosseous nerve (PIN) is closely related to the proximal radius, and it is at risk when approaching the proximal forearm from the ventral and lateral side. This anatomic study analyzes the location of the PIN in relation to the proximal radius depending on forearm rotation by means of a novel investigation design. The purpose of this study is to define landmarks to locate the PIN intraoperatively in order to avoid neurological complications.

Influence of a proprioceptive training on functional ankle stability in young speed skaters - a prospective randomised study.

The influence of a 12-week-proprioceptive training on functional ankle stability was investigated in young speed skaters. Twenty-eight speed skaters were randomly divided into an intervention (n = 14) and into a control group (n = 14). A 15-min circle training was performed 5 times per week over a 12-week period.

Two-year results of vertebral body stenting for the treatment of traumatic incomplete burst fractures.

Purpose: Vertebral body stenting (VBS) was developed to prevent loss of reduction after balloon deflation during kyphoplasty. The aim of this study is the radiological and clinical mid-term evaluation of traumatic incomplete burst fractures treated by vertebral body stenting.

Material And Methods: This retrospective study included patients with traumatic thoracolumbar incomplete burst fractures treated with VBS between 2009 and 2010.

Effective teaching modifies medical student attitudes toward pain symptoms.

Introduction: Recent studies have raised the question of whether last year medical students and first year residents show an adequate attitude toward their patient's pain as reflected by prescribed pain medication. Underuse of analgetics could be demonstrated in several studies even after a correct diagnosis of pain was made and has led to the term "oligoanalgesia." Our study was aimed at evaluating the potential of improving student attitudes toward pain by changing the curriculum during the last year of medical education.
