Abstract
Ankle injuries are a huge medical and socioeconomic problem. Many people have a traumatic injury of the ankle, most of which are a result of sports. Total costs of treatment and work absenteeism due to ankle injuries are high. The prevention of recurrences can result in large savings on medical costs. A multidisciplinary clinical practice guideline was developed with the aim to prevent further health impairment of patients with acute lateral ankle ligament injuries by giving recommendations with respect to improved diagnostic and therapeutic opportunities. The recommendations are based on evidence from published scientific research, which was extensively discussed by the guideline committee. This clinical guideline is helpful for healthcare providers who are involved in the management of patients with ankle injuries.

Laurens
Kaas, “Radial head fracture: a potentially complex injury"
10 April 2012, 2.00
p.m., Agnietenkapel, Oudezijds Voorburgwal 231, 1012 EZ Amsterdam.
Although
knowledge of radial head fractures has increased over the past few decades,
many aspects of this common fracture are still not clear. This thesis contains
four parts, in each of which an issue relating to radial head fractures was
discussed. In part I elbow anatomy, etiology, diagnosis and treatment of radial
head fractures were addressed. The epidemiology of radial head fractures and
their associated osseous injuries, as well as the relationship between radial
head fractures and osteoporosis, were discussed in part II. Part III focused on
the incidence and clinical relevance of osseous, cartigilanous, and ligamentous
associated injuries in elbows with a radial head fracture. In part IV a
systematic review was performed on the treatment of stable Mason type II
fractures without associated fractures or elbow dislocation.

Abstract
ABSTRACT:
BACKGROUND:
Acute lateral ankle ligament injuries are very common problems in present health care. Still there is no hard evidence about which treatment strategy is superior. Current evidence supports the view that a functional treatment strategy is preferable, but insufficient data are present to prove the benefit of external support devices in these types of treatment. The hypothesis of our study is that external ankle support devices will not result in better outcome in the treatment of acute ankle sprains, compared to a purely functional treatment strategy. Overall objective is to compare the results of three different strategies of functional treatment for acute ankle sprain, especially to determine the advantages of external support devices in addition to functional treatment strategy, based on balance and coordination exercises.
METHODS/DESIGN:
This study is designed as a randomised controlled multi-centre trial with one-year follow-up. Adult and healthy patients (N = 180) with acute, single sided and first inversion trauma of the lateral ankle ligaments will be included. They will all follow the same schedule of balancing exercises and will be divided into 3 treatment groups, 1. pressure bandage and tape, 2. pressure bandage and brace and 3. no external support. Primary outcome measure is the Karlsson scoring scale; secondary outcomes are FAOS (subscales), number of recurrent ankle injuries, Visual Analogue Scales of pain and satisfaction and adverse events. They will be measured after one week, 6 weeks, 6 months and 1 year.
DISCUSSION:
The ANKLE TRIAL is a randomized controlled trial in which a purely functional treated control group, without any external support is investigated. Results of this study could lead to other opinions about usefulness of external support devices in the treatment of acute ankle sprain.
TRIAL REGISTRATION:
Netherlands Trial Register (NTR): NTR2151.
Organized by the AFAS (Ankle & Foot ASsociation) section of ESSKA in collaboration with the Hospital for Special Surgery, this meeting has been established on the basis of requests from leaders in the field to consolidate and share information, which can collectively serve as a basis for international collaboration and innovation.
The congress was a huge success, with many attendees from all over the world. Over 150 attendees were present to discuss the current state of cartilage repair of the ankle. State of the art lectures were held by the world wide leaders in the field. A "young gun" session was held in which the future leaders would address their view on ankle cartilage repair.
The organization will set-up future biannual congresses to ensure an up to date consensus on cartilage repair of the ankle and support future research in this field

Abstract
PURPOSE:
The purpose of this
study was to determine whether preoperative computed tomography (CT) of
the ankle joint in full plantar flexion is a reliable and accurate tool
to determine the anterior arthroscopic accessibility of talar
osteochondral defects (OCDs).
METHODS:
Twenty
consecutive patients were prospectively studied. All patients had an OCD
of the talar dome and had a preoperative CT scan of the affected ankle
in maximum plantar flexion. Accessibility of the OCD was defined by the
distance between the anterior border of the OCD and the anterior distal
tibial rim. This distance was measured on sagittal CT reconstructions by
2 investigators. The reference standard was the distance between the
same landmarks measured during anterior ankle arthroscopy by an
orthopaedic surgeon blinded to the CT scans. Intraobserver and
interobserver reliability of CT, as well as the correlation and
agreement between CT and arthroscopy, were calculated.
RESULTS:
The
measured distance between the anterior border of the OCD and the
anterior distal tibial rim ranged from -3.1 to 9.1 mm on CT and from
-3.0 to 8.5 mm on arthroscopy. The intraobserver and interobserver
reliability of the measurements made on CT scans (intraclass correlation
coefficients >0.99, P < .001), as well as the correlation between
CT and arthroscopy, were excellent (r = 0.98, P < .001).
CONCLUSIONS:
Measurements
on CT scans of the ankle in full plantar flexion are a reliable and
accurate preoperative method to determine the in situ arthroscopic
location of talar OCDs.
LEVEL OF EVIDENCE: Level II, development of diagnostic criteria based on consecutive patients.

4 April 2012 11.00 a.m., Lutherse Kerk, Singel 411, 1012 WN Amsterdam.
Chronic Achilles tendon pathology is one of the biggest problems in sports involving running and jumping. However, is is not always related to excessive physical activity. Thirty percent of patients have a sedentary lifestyle. Recalcitrant Achilles tendons may cause pain for years and often resistant to any form of treatment. The cause of pain has not yet been clarified, and therefore its treatment is challenging and often unsatisfactory. The aim of this thesis was to elucidate the cause of pain, to develop appropriate assessment tools, to invent minimally invasive treatment methods, and to optimize diagnostic and endoscopic methods for chronic Achilles tendon problems.
On the 13th of April 2012 the ESSKA-AFAS (Ankle and Foot Associates) day will be organised in Moscow in cooperation with ASTAOR (Association of Sports Traumatology, Arthroscopy and Orthopaedic Surgery and Rehabilitation).
