Analysis of metacarpal V fractures of an interdisciplinary emergency room of an urban German hospital from a forensic viewpoint

2015

Metacarpal V fractures, especially metacarpal neck fractures, are known to the forensic society as a ‘boxer’s fracture’ and are described as being mostly caused by punching an immovable or firm object with force with a closed fist. To our knowledge there is no larger study that examines these fractures under forensic considerations of epidemiology. Our study includes the analysis of metacarpal V fractures in an interdisciplinary, academic and university-affiliated emergency department of an urban hospital over a period of three years. Emergency data sheets were systematically analysed and X-rays evaluated. The results were compared with the existing literature.

Influence of the metaphysis positioning in a new reverse shoulder prosthesis

2016

Aim of this work is to investigate the behaviour of a new reverse shoulder prosthesis, characterized by a humeral metaphysis with a variable offset, designed to increase the range of movements and to reduce the impingement. In particular, by means of virtual prototypes of the prosthesis, different offset values of the humeral metaphysis have been analysed in order to find the best positioning able to maximize the range of movements of the shoulder joint. The abduction force of the deltoid, at different offset values, has been also estimated. The study has been organized as follows. In the first step, the point clouds of the surfaces of the different components of the prosthesis have been ac…

Ultrasonographic Measurements of the Achilles Tendon in Elderly Athletes and Sedentary Men

1994

Ultrasonography was performed on the Achilles tendon of the dominant limb of 18 male elderly athletes and 11 sedentary men, aged 70 to 80 years. The tendons were examined with a real-time linear array scanner using a 7.5 MHz transducer. Both longitudinal and transverse images were taken. The mean width of the Achilles tendon was significantly larger in the athletes than in the control subjects. The tendon thickness and cross-sectional area did not differ significantly between the groups, but the figures may indicate a tendency for larger cross-sectional area in the athletes. The results suggest tendon hypertrophy following long-term training.

Personality of Fragility Fractures of the Pelvis

2017

The personality of pelvic fractures in the elderly differs in many ways from pelvic ring lesions in adults. Only high-energy trauma leads to pelvic ring disruptions. Concomitant lesions of the soft tissues occur frequently. In the elderly, low-energy falls are the rule. The most important symptom is pain, which restricts mobility. Hemodynamic instability in fragility fractures of the pelvis is rare. Emergency stabilization with pelvic binders or sheets, C-clamping or emergency external fixation are not needed. Arteriography and selective embolization is only recommended in the rare patients, who develop an active arterial bleeding due to the pelvic fracture. Especially patients, who are tre…

Foam rolling is thought to improve muscular performance and flexibility as well as to alleviate muscle fatigue and soreness. For this reason, foam rolling has become a popular intervention in all kinds of sport settings used to increase the efficiency of training or competition preparation as well as to speed post-exercise recovery. The objective of this meta-analysis was to compare the effects of foam rolling applied before (pre-rolling as a warm-up activity) and after (post-rolling as a recovery strategy) exercise on sprint, jump, and strength performance as well as on flexibility and muscle pain outcomes and to identify whether self-massage with a foam roller or a roller massager is more…

Type of surgery is associated with pain and walking difficulties among older people with previous hip fracture

2015

Aim The aim was to assess the level of lower body pain among people with previous femoral neck fracture, and whether the type of surgery was associated with pain and physical function a mean of 2 years after surgery. Methods The study included 115 community-dwelling older adults aged 60 years and older with previous femoral neck fracture, and 31 reference subjects without previous lower limb injuries. A total of 30 patients had internal fixation surgery, 70 had hemiarthroplasty and 15 had total hip replacement. All patients had surgery in the same hospital and received typical inpatient rehabilitation. From 1.6 months to 7.5 years after the fracture, the patients underwent examination inclu…

Background: We prospectively tested technical feasibility and clinical outcome of percutaneous ultrasound-guided tenotomy of long head of biceps tendon (LHBT). Methods: We included 11 patients (6 women; age: 73 ± 8.6 years) with symptomatic full-thickness rotator cuff tear and intact LHBT, in whom surgical repair was not possible/refused. After ultrasound-guided injection of local anesthetic, the LHBT was cut with a scalpel under continuous ultrasound monitoring until it became no longer visible. Pain was recorded before and at least six months after procedure. An eight-item questionnaire was administered to patients at follow-up. Results: A median of 4 tendon cuts were needed to ensure com…

The structural validity of the Finnish version of the Disabilities of the Arm, Shoulder and Hand: A Rasch model analysis

2020

Introduction The construct validity of the Disabilities of the Arm, Shoulder and Hand questionnaire (DASH) has previously been questioned. The purpose of this study was to evaluate the measurement properties of the Finnish version of the DASH for assessing disability in patients with hand complaints using Rasch Measurement Theory. Methods A cohort of 193 patients with typical hand and wrist complaints were recruited at a surgery outpatient clinic. The DASH scores were analysed using the Rasch model for differential item functioning, unidimensionality, fit statistics, item residual correlation, coverage/targeting and reliability. Results In the original DASH questionnaire, the item response …
