Magnetic resonance and ultrasound in achilles tendinopathy: Predictive role and response assessment to platelet-rich plasma and adipose-derived strom…
2017
To assess the correlation between magnetic resonance and ultrasound findings and clinical outcome after intratendinous injection of leucocyte-rich platelet-rich plasma or adipose-derived stromal vascular fraction in patients with non-insertional Achilles tendinopathy.Forty-three patients (age: 47.8±5.1, range 29-55) with unilateral or bilateral non-insertional Achilles tendinopathy (58 tendons overall) were randomly assigned to platelet-rich plasma (22 patients, 28 tendons) or adipose-derived stromal vascular fraction (21 patients, 30 tendons) injection group. All patients underwent magnetic resonance (tendon cross-sectional area, signal intensity, maximum anteroposterior thickness were mea…
Circulating hematopoietic progenitor cells in runners
2002
Because endurance exercise causes release of mediators and growth factors active on the bone marrow, we asked whether it might affect circulating hematopoietic progenitor cells (HPCs) in amateur runners [ n = 16, age: 41.8 ± 13.5 (SD) yr, training: 93.8 ± 31.8 km/wk] compared with sedentary controls ( n = 9, age: 39.4 ± 10.2 yr). HPCs, plasma cortisol, interleukin (IL)-6, granulocyte colony-stimulating factor (G-CSF), and the growth factor fms-like tyrosine kinase-3 (flt3)-ligand were measured at rest and after a marathon (M; n = 8) or half-marathon (HM; n = 8). Circulating HPC counts (i.e., CD34+cells and their subpopulations) were three- to fourfold higher in runners than in controls at b…
Emergency toe-to-hand transfer for post-traumatic finger reconstruction: A multicenter case series
2019
Abstract Background The aim of this paper was to evaluate the outcomes of a homogenous series of emergency with a toe-to-hand transfer reconstructions with a different timing: immediate (same surgical step with the debridement), primary (in the first 24 h), early (24–72 h after the debridement) or delayed (72 h-7 days). Materials and methods Between 2001 and 2011, 31 patients received an immediate reconstruction with a toe-to-hand transfer. Data on indications, timing, type of surgery, complications and outcomes (sensory and motor recovery, patient satisfaction) were extrapolated and recorded. Results Most of the procedures in our series (71%) were performed in the first 24 h. Survival rate…
Evaluation of robot-guided minimally invasive implantation of 2067 pedicle screws
2017
ObjectiveRecent studies have investigated the role of spinal image guidance for pedicle screw placement. Many authors have observed an elevated placement accuracy and overall improvement of outcome measures. This study assessed a bi-institutional experience following introduction of the Renaissance miniature robot for spinal image guidance in Europe.MethodsThe medical records and radiographs of all patients who underwent robot-guided implantation of spinal instrumentation using the novel system (between October 2011 and March 2015 in Mainz and February 2014 and February 2016 in Regensburg) were reviewed to determine the efficacy and safety of the newly introduced robotic system. Screw posit…
Prospective Randomized Trial of Electrolysis for Chronic Plantar Heel Pain
2018
Background: Chronic plantar heel pain (CPHP) is a common condition with high prevalence rates and a projected cost of treatment of US$192 to US$376 million. There are several therapeutic approaches and there is increased interest in treatments aimed at the regeneration of tissues with poor healing potential. Our purpose was to investigate the effectiveness of ultrasound-guided percutaneous needle electrolysis in chronic plantar heel pain. Methods: A total of 73 patients with a clinical and ultrasonographic diagnosis of plantar heel pain unrelated to systemic inflammatory disease who had not received any other treatment in the previous 6 months on the affected foot were randomly allocated to…
Assessment of Construct Validity of the Oswestry Disability Index and the Scoliosis Research Society–30 Questionnaire (SRS-30) in Patients With Degen…
2019
Observational cohort study.To measure and compare the structural validity of the Oswestry Disability Index (ODI) and the Scoliosis Research Society-30 (SRS-30) questionnaire in an adult population with prolonged degenerative thoracolumbar disease.The ODI and the SRS-30 are commonly used patient-reported outcome instruments to assess back-specific disability and symptoms related to scoliosis. Still, these instruments have not been validated for degenerative spinal disease with different stages of deformity.Altogether, 637 consecutive adult patients with degenerative spinal pathologies were included. The patients completed the ODI (version 2.0), the 23 preoperative items of the SRS-30, a gene…
Analysis of the upper cervical spine stiffness during axial rotation: A comparative study among patients with tension-type headache or migraine and a…
2017
Abstract Background Many studies reported the implication of the cervical musculoskeletal system in patients with tension type headache and migraine. The objective of this study is to investigate the upper cervical spine stiffness features in axial rotation among headache patients in comparison with a healthy population. Methods 48 subjects including 30 migraine patients with/without aura and 18 patients with tension-type headache, aged between 18 and 60 years (mean 36, SD 11 years) have been evaluated. Stiffness measurements were carried out for passive axial rotation using a torque meter device. The flexion-rotation test was used to emphasize assessment of the upper cervical spine. Findin…
Selective activation of shoulder, trunk, and arm muscles: A comparative analysis of different push-up variants
2015
Context The push-up is a widely used exercise for upper limb strengthening that can be performed with many variants. A comprehensive analysis of muscle activation during the ascendant phase (AP) and descendant phase (DP) in different variants could be useful for trainers and rehabilitators. Objective To obtain information on the effect of different push-up variants on the electromyography (EMG) of a large sample of upper limb muscles and to investigate the role of the trunk and abdomen muscles during the AP and DP. Design Cross-sectional study. Setting University laboratory. Patients or Other Participants Eight healthy, young volunteers without a history of upper extremity or spine injury.…
The Advantages of Type III Scaphoid Nonunion Advanced Collapse (SNAC) Treatment With Partial Carpal Arthrodesis in the Dominant Hand: Results of 5-ye…
2018
Introduction The SNAC wrist (Scaphoid nonunion advanced collapse) is one of the complications following scaphoid fractures treated conservatively and one of the causes of wrist arthritis that the hand surgeon has to face most frequently. In these cases surgical management is usually warranted. Materials and methods In the set time frame of 6 years we treated 15 SNAC wrist cases. On average patients underwent surgery five years after the trauma. All patients were treated via dorsal incision with partial carpal arthrodesis and total scaphoidectomy, associated with denervation of the posterior interosseous nerves. A plaster cast was applied to all patients for 3 weeks postoperatively. In the p…
Progression of untreated mild thoracic Scheuermann's kyphosis – Radiographic and functional assessment after mean follow-up of 46 years
2017
There is no data available on the radiographic development of the Scheuermann's deformity. Our purpose was to investigate radiographic deformity progression and the relation between kyphosis progression and clinical outcome in patients with untreated Scheuermann's kyphosis.Thoracic kyphosis (Th4-Th12) was measured from standing lateral radiographs in 19 patients at baseline and after mean 46-year follow-up. Mean age at baseline was 19.2 and at follow-up 64.7 years. At follow-up, height, weight, hand grip strength, and hamstring tightness were measured, and sit-to-stand and walking tests were performed. Additionally general health and quality of life questionnaires were administered.The mean…
