Hemodynamic impact of isobaric levobupivacaine versus hyperbaric bupivacaine for subarachnoid anesthesia in patients aged 65 and older undergoing hip…

2014

Background The altered hemodynamics, and therefore the arterial hypotension is the most prevalent adverse effect after subarachnoid anesthesia. The objective of the study was to determine the exact role of local anesthetic selection underlying spinal anesthesia-induced hypotension in the elderly patient. We conducted a descriptive, observational pilot study to assess the hemodynamic impact of subarachnoid anesthesia with isobaric levobupivacaine versus hyperbaric bupivacaine for hip fracture surgery. Description Hundred twenty ASA status I-IV patients aged 65 and older undergoing hip fracture surgery were enrolled. The primary objective of our study was to compare hemodynamic effects based …

Effects of resistance training on lower-extremity impairments in older people with hip fracture

2008

Abstract Portegijs E, Kallinen M, Rantanen T, Heinonen A, Sihvonen S, Alen M, Kiviranta I, Sipila S. Effects of resistance training on lower-extremity impairments in older people with hip fracture. Objective To study the effects of resistance training on muscle strength parameters, mobility, and balance. Design Randomized controlled trial. Setting Research laboratory and senior gym. Participants Population-based sample of eligible 60- to 85-year-old community-dwelling men and women 0.5 to 7.0 years after hip fracture. Forty-six people had no contraindications and were willing to participate in the exercise trial. Intervention Twelve-week intensive progressive strength-power training (n=24),…

Effects of a multicomponent home-based physical rehabilitation program on mobility recovery after hip fracture: a randomized controlled trial.

2013

To investigate whether a home-based rehabilitation program for community-dwelling older people with recent hip fracture is more effective than standard care in improving mobility recovery and reducing disability.Randomized, controlled, parallel-group trial.Rehabilitation in participants' homes; measurements in university-based laboratory and local hospital.Clinical population of community-dwelling men and women (aged 60+) recovering from hip fracture. Participants were randomly assigned into control (n = 41) or intervention (n = 40) groups on average 42 ± 23 days after discharge home.A yearlong multicomponent home-based rehabilitation aimed at promoting mobility recovery and physical functi…

Mid- to long-term results after bipolar radial head arthroplasty.

2009

Background Radial head arthroplasty is considered the treatment of choice for unreconstructable radial head fractures in the acute fracture situation. Although short-term results in the current literature are promising, replacement of the radial head remains controversial as long-term results are still missing. We report our 8.8-year results after treatment with a bipolar radial head prosthesis by Judet. Materials and methods In our department, 19 patients were treated with bipolar radial head arthroplasty between 1997 and 2001. Seventeen of these patients—14 men and 3 women—were examined retrospectively after 106 months (range, 78-139). Of these, 9 patients were treated primarily, 7 patien…

Modular megaprosthesis reconstruction for oncological and non-oncological resection of the elbow joint

2016

Abstract Background Reconstruction of large bone defects around the elbow joint is surgically demanding due to sparse soft tissue coverage, complex biomechanics and the close proximity to neurovascular structures. Modular megaprostheses are established reconstruction tools for the elbow, but only small case series have been reported in the literature. Methods Thirty-six patients who underwent reconstruction of the elbow joint with a modular megaprosthesis were reviewed retrospectively. In 31 patients (86.1%), elbow replacement was performed after resection of a bone tumour, whereas five non-oncological patients (13.9%) underwent surgery because of a previous failed elbow reconstruction. Fun…

Locking plates for corrective osteotomy of malunited dorsally tilted distal radial fractures: a biomechanical study.

2005

The purpose of the study was to compare the biomechanical properties of five different palmar fixation plate designs in a distal radius osteotomy cadaver model. A 1 cm metaphyseal osteotomy gap was made to simulate a corrective osteotomy and the osteotomy plated. Axial load was applied to the distal end of each construct by a material testing machine under control of a motion analysis video system. The specimens were arranged into five implant groups of eight specimens each. No test group developed deformity and movement of the fracture gap greater than 2 mm with a load of 100 N. Increasing the load to 250 N revealed statistically significant differences in stiffness and failure load betwe…

Incidence and costs of hip fractures compared to acute myocardial infarction in the Italian population: a 4-year survey

2007

Introduction Few data are available about the incidence and costs of hip fractures in Italy. We aimed to determine the impact of hip fractures vs. acute myocardial infarction (AMI). Methods We studied the national hospitalization database to calculate their incidence and costs in adults aged ≥45 between 1999 and 2002. Results In 2002, there were 86,719 hip fractures with a 10.0% increase over 4 years. We observed a predominance of women (77.1%) and a strong age effect: 92.7% of patients were ≥65 years old and 80% of fractures occurred in women aged ≥75, showing a clear relationship with the incidence of osteoporosis. Hospitalizations due to AMI after 45 years of age in 1999 were only 9% hig…

Assessment of Lower Limb Load Distribution in Patients Treated with the Ilizarov Method for Tibial Nonunion

2021

BACKGROUND Successful treatment of tibial nonunion should lead to a complete bone union, lack of pain, and pathological mobility of the lower extremity, as well as to the achievement of satisfactory joint mobility and muscle strength, which in turn improves its biomechanics. The objective of this study was to assess the load placed on the lower limbs in patients subjected to treatment with the Ilizarov method due to aseptic tibial nonunion. MATERIAL AND METHODS This research involved 24 participants (average age, 55 years). All were diagnosed with aseptic tibia nonunion and treated with the Ilizarov external fixator between 2000 and 2017. The control group was matched to the treated group i…

Number and Locations of Screw Fixation for Volar Fixed-Angle Plating of Distal Radius Fractures: Biomechanical Study

2010

Purpose To compare the biomechanical properties of different numbers and locations of screws in a multidirectional volar fixed-angle plate in a distal radius osteotomy cadaver model. Methods We created an extra-articular fracture in 16 pairs of fresh-frozen human cadaver radiuses. The 32 specimens were randomized into 4 groups. All fractures were fixated with a multidirectional volar fixed-angle plate. We tested 4 different screw-placement options in the distal fragment. The distal fragment was fixed with 4 locking screws in the distal row of the plate in group a, and with 4 locking screws alternately in the distal and proximal rows in group b. In group c, 3 locking screws were used in the …
