Varus ankle osteoarthritis (OA) is typically associated with peritalar instability, which may result in altered subtalar joint position. This study aimed to determine the extent to which total ankle replacement (TAR) in varus ankle OA can restore the subtalar position alignment using 3-dimensional semi-automated measurements on WBCT. Fourteen patients (15 ankles, mean age 61) who underwent TAR for varus ankle OA were retrospectively analyzed using semi- automated measurements of the hindfoot based on pre-and postoperative weightbearing WBCT (WBCT) imaging. Eight 3-dimensional angular measurements were obtained to quantify the ankle and subtalar joint alignment. Twenty healthy individuals were served as a control groups and were used for reliability assessments. All ankle and hindfoot angles improved between preoperative and a minimum of 1 year (mean 2.1 years) postoperative and were statistically significant in 6 out of 8 angles (P<0.05). Values The post-op angles were in a similar range to as those of healthy controls were achieved in all measurements and did not demonstrated statistical difference (P>0.05). Our findings indicate that talus repositioning after TAR within the ankle mortise improves restores the subtalar position joint alignment within normal values. These data inform foot and ankle surgeons on the amount of correction at the level of the subtalar joint that can be expected after TAR. This may contribute to improved biomechanics of the hindfoot complex. However, future studies are required to implement these findings in surgical algorithms for TAR in prescence of hindfoot deformity.

Aims

Implant failure has become more common as the number of primary total ankle arthroplasties (TAAs) performed has increased. Although revision arthroplasty has gained attention for functional preservation, the long-term results remain unclear. This study aimed to assess the long-term outcomes of revision TAA using a mobile-bearing prosthesis in a considerably large cohort; the risk factors for failure were also determined.

Methods

This single-centre retrospective cohort study included 116 patients (117 ankles) who underwent revision TAA for failed primary TAA between July 2000 and March 2010. Survival analysis and risk factor assessment were performed, and clinical performance and patient satisfaction were evaluated preoperatively and at last follow-up.

Aims

To assess the effect of age on clinical outcome and revision rates in patients who underwent total ankle arthroplasty (TAA) for end-stage ankle osteoarthritis (OA).

Methods

A consecutive series of 811 ankles (789 patients) that underwent TAA between May 2003 and December 2013 were enrolled. The influence of age on clinical outcome, including the American Orthopaedic Foot and Ankle Society (AOFAS) hindfoot score, and pain according to the visual analogue scale (VAS) was assessed. In addition, the risk for revision surgery that includes soft tissue procedures, periarticular arthrodeses/osteotomies, ankle joint debridement, and/or inlay exchange (defined as minor revision), as well as the risk for revision surgery necessitating the exchange of any of the metallic components or removal of implant followed by ankle/hindfoot fusion (defined as major revision) was calculated.

Introduction

Distal radius fractures (DRF) are a common injury in the A&E departments, being a major cause of disability of the upper extremity. The aim of this prospective study is to assess the possible association between objective physical variables such as wrist range of movement (ROM), radiological parameters, and upper extremity disability (measured by the DASH questionnaire), after conservative treatment of DRF.

Patients and methods

44 patients with non-operatively managed DRF were enrolled in a prospective cohort study from July 2007 till September 2009.

Inclusion criteria: unilateral DRF in skeletally mature patients, treated non-operatively with closed reduction and cast. Patients who sustained a previous fracture of the wrist, or bilateral wrist fracture, or with dementia, were excluded.

After the closed reduction and inmovilization of the fracture in the A&E department we asked the patients to complete the DASH questionnaire, referring to their baseline pre-fracture state.

All fractures were classified according to the AO classification.

After one year, 36 patients were still available for follow-up purposes. We assesed the following objective physical variables: ROM of both wrists: flexion/extension arc and pronation/supination arch. We recorded the following radiologic parameters: radial angulation, volar angulation and radial shortening. The patient-perceived results were measured by the DASH questionnaire, while pain was measured using the VAS scale.

Statistical analysis was performed using the SPSS 15.0.

Introduction: Terrorist bombings, with catastrophic resultant blast injuries, have been increasing in frequency during past 25 years. Limbs injuries is common among survivors. Four crowded trains were attacked in Madrid on March 11, 2004. Injuries were sustained by 1550 people, 198 of whom died, mostly at the scene. Because the building station did not collapse, as in other attacks, the number of multiple injured patients who survive were high. 509 patients were attended at our Hospital in the emergency unit during the first six hours after the explosions, 80 of whom require hospitalization. Three patients died on arrival. Data about transport from the scene, injury type, diagnostic test and treatment and functional outcome were obtained from the Hospital Trauma Registry.

The day at the Hospital:

The first patient arrived at 08:00, when the daily clinical meeting for the trauma admissions began. During the first hour, an effort was made in order to triage victims and organize the requirements for operating room and ICU treatment. All scheduled operations were aborted and six orthopaedic trauma teams were prepared to start operations immediately. A separate area in the Hospital was established to treat minor injuries. All patients were operated within the first 8 hours.

Injury characteristics: 39 patients admitted with an ISS higher than 9 presented the most severe injuries. A study group was made with these patients. Mean age were 33,6. The mean RTS were 6,87, mean ISS 21,94, and mean NISS 26,15, revealing the high frequency of multisistemic injuries. The most frequently injury in these group were pulmonary blast injury, with a mean AIS for thorax of 2,7 points.74% of patients had some type of pulmonary blast injury.

Limb injuries: 12 (25%) patients had open fractures, combined in all cases with pulmonary blast. Open Gustilo IIIb and IIIc occur in seven patients. Soft tissue injuries caused by small fragments were also frequent. Two patients presented SCIWORA like injuries of the thoracic medullary cord. All patients were operated in the first six hours after the explosion. A detailed description of the injuries, treatment and functional outcome will be presented. Functional outcome were analyzed by physical and psychological scales at six and twelve months after the attack. Scales used were SF-36(short form 36), EQ-5D (Euroqol), CES-D( Center for Epidemiologic Studies Depression Scale) and AVS. Comparison with a similar general trauma group revealed poorer functional outcome at six months for the study group.

Conclusions: The bombing attack in Madrid was the first massive attack over civilian population in Europe since WW II. Functional outcomes were worse than expected in patients with skeletal injuries. In spite of the good results of initial treatment in our experience, we think that there is no country prepared sufficiently to treat this new type of massive casualties.

Background: Pelvic fractures are frecuently associated with massive intrapelvic bleeding from venous or arterial sources. Different treatment algorithms has been proposed in order to stablish early control of haemorragic sites, mostly based on external fixation/angiography. The aim of present study was to evaluate the clinical evolution of 70 pelvic fractures with uncontrolled hypotension treated with combined ex fix/angio based on fracture pattern.

Materials and methods: Case serie . We analyzed a serie of patients admitted at our center between 1994 and 2004 with pelvic fracture and haemodinamic instability , treated by the same algorithm. Decision-making for the first treatment(angio vs external fixation) were based on the type of pelvic fracture. Patients was considered unstable if PAS was less than 90mmHg or the patients needs more than two blood products replacement in first 24 hours.

Results: External fixation was used in 45 patients(64%) and 37 patients were treated by angio. We found active arterial bleeding in 31 cases (44%). The combination of both treatment was used in 20 patients. Laparotomy was performed in 21 patients. Incidence of sistemic complications were high . Mortality was 26% . Mortality were higher in two groups: patients with TBI and those treated by laparotomy.

Conclusions: Arterial lesions demostrated by angio were high in our study(44%). In our experience a combined algorithm using both external fixation or angio based on type fracture control intrapelvic bleeding in most cases , although mortality in patients with pelvic fractre and haemodinamic instabilty remains high.
