Objectives. Aged trauma patients are at high risk for various comorbidities and loss of function following hip fracture. Consequently a multidisciplinary approach for the treatment of these patients has become more famous in order to maintain the patients” activity level and health status prior to trauma. This study evaluates the effect of a multidisciplinary inpatient rehabilitation on the short- and long-term
In a clinical setting, there is a need for simple gait kinematic measurements to facilitate objective unobtrusive patient monitoring. The objective of this study is to determine if a learned classification model's output can be used to monitor a person's recovery status post-TKA. The gait kinematics of 20 asymptomatic and 17 people with TKA were measured using a full-body Xsens model1. The experimental group was measured at 6 weeks, 3, 6, and 12 months post-surgery. Joint angles of the ankle, knee, hip, and spine per stride (10 strides) were extracted from the Xsens software (MVN Awinda studio 4.4)1. Statistical features for each subject at each evaluation moment were derived from the kinematic time-series data. We normalised the features using standard scaling2. We trained a logistic regression (LR) model using L1-regularisation on the 6 weeks post-surgery data2–4. After training, we applied the trained LR- model to the normalised features computed for the subsequent timepoints. The model returns a score between 0 (100% confident the person is an asymptomatic control) and 1 (100% confident this person is a patient). The decision boundary is set at 0.5. The classification accuracy of our LR-model was 94.58%. Our population's probability of belonging to the patient class decreases over time. At 12 months post-TKA, 38% of our patients were classified as asymptomatic.
Scoliosis correction surgery is one of the longest and most complex procedures of all orthopedic surgery. The complication rate is therefore not negligible and is particularly high when the surgery is performed in patients with neuromuscular or connective tissue disease or complex genetic syndromes. In fact, these patients have various comorbidities and organ deficits (respiratory capacity, swallowing / nutrition, heart function, etc.), which can compromise the outcome of the surgery. In these cases, an accurate assessment and preparation for surgery is essential, also making use of external consultants. To make this phase simpler, more effective and homogeneous, a multidisciplinary path of peri-operative optimization is being developed in our Institute, which also includes the possibility of post-operative hospitalization for rehabilitation and recovery. The goal is to improve the basic
Abstract. Objectives. Single-event multilevel surgery (SEMLS) is the standard orthopaedic treatment for gait abnormalities in children with diplegic cerebral palsy (CP). The primary aim of this study was to report the long-term functional mobility of these patients after surgery. The secondary aim was to assess the relationship between functional mobility and quality of life (QoL). Methods. Patients were included if they met the following criteria: 1) diplegic CP; 2) Gross Motor Function Classification System (GMFCS) I to III; 3) SEMLS at age ≤ 18. A total of 61 patients, mean age at surgery 11 years eight months (SD 2y 5m), were included. A mean of eight years (SD 3y 10m) after SEMLS, patients were contacted and asked to complete the Functional Mobility Scale (FMS) questionnaire over the telephone and given a weblink to complete an online version of the CP QOL Teen. FMS was recorded for all patients and CP QOL Teen for 23 patients (38%). Results. Of patients graded GMFCS I and II preoperatively, at long-term follow-up the proportion walking independently at home, school/work and in the community was 71% (20/28), 57% (16/28) and 57% (16/28), respectively. Of patients graded GMFCS III preoperatively, at long-term follow-up 82% (27/33) and 76% (25/33) were walking either independently or with an assistive device at home and school/work, respectively, while over community distances 61% (20/33) required a wheelchair. The only significant association between QoL and functional mobility was better ‘feelings about function’ in patients with better home FMS scores (r=0.55; 95% confidence interval 0.15 to 0.79; p=0.01). Conclusion. The majority of children maintained their preoperative level of functional mobility at long-term follow-up after SEMLS. Despite the favourable functional mobility, there was little evidence to establish a link between
Introduction and Objective. Total shoulder replacement is a common elective procedure offered to patients with end stage arthritis. While most patients experience significant pain relief and improved function within months of surgery, some remain unsatisfied because of residual pain or dissatisfaction with their
Physical functioning in patients undergoing hip surgery is commonly assessed in three ways: patient-reported outcome measure (PROM), performance test, or clinician-administered measure. It is recommended that several types of measures are used concurrently to capture an extended picture of function. Patient fatigue and burden, time, resources and logistical constraints of clinic and research appointments mean that collecting multiple measures is seldom feasible, leading to focus on a limited number of measures, if not a single one. While there is evidence that performance-tests and PROMs do not fully correlate, correlations between PROMs, performance tests and clinician-administrated measures are yet to be evaluated. It is also not known if the associations between function and patient characteristics depend on how function is measured. The aim of our study was to use different measures to assess function in the same group of patients before their hip surgery to determine 1. how well PROMs, performance tests and clinician-administrated measures correlate with one another and 2. Whether these measures are associated with the same patient characteristics. We conducted a cross-sectional analysis of the pre-operative information of 125 participants listed for hip replacement. The WOMAC function subscale, Harris Hip Score (HHS) and walk-, step- and balance-tests were assessed by questionnaire or during a clinic visit. Participant socio-demographics and medical characteristics were also collected. Correlations between functional measures were investigated with correlation coefficients (r). Regression models were used to test the association between the patient's characteristics and each of the three types of functional measures. None of the correlations between the PROM, clinician-administrated measure and performance tests were very high (r<0.90). The highest correlations were found between the WOMAC-function and the HHS (r=0.7) or the Walk-test (r=0.6), and between the HHS and the walk-test(r=0.7). All the other performance-tests had low correlations with the other measures(r ranging between 0.3 and 0.5). The associations between patient characteristics and functional scores varied by type of measure. Psychological status was associated with the WOMAC function (p-value<0.0001) but not with the other measures. Age was associated with the performance test measures (p-value ranging from ≤0.01 to <0.0001) but not with the WOMAC function. The clinician-administered (HHS) measure was not associated with age or psychological status. When evaluating function prior to hip replacement clinicians and researchers should be aware that each assessment tool captures different aspects of function and that patient characteristics should be taken into account. Psychological status influences the perception of function; patients may be able to do more than they think they can do, and may need encouragement to overcome anxiety. A performance test like a walk-test would provide a more comprehensive assessment of function limitations than a step or balance test, although performance tests are influenced by age. For the most precise description of
Background & Objectives. Sensory and motor manifestations in carpal tunnel syndrome (CTS) are well documented, whereas the associated autonomic dysfunction is often overlooked. The aim of this study is to demonstrate that autonomic dysfunction of the CTS hands can be quantified by measuring skin capacitance. Methods. Patients with clinical and electrophysiological signs of idiopathic carpal tunnel syndrome meeting the inclusion criteria were recruited. The patients were also scored based on the Brigham carpal tunnel severity score. Skin capacitance was measured using Corneometer CM825 (C&K Electronic, GmbH). The measurements were taken from the palmar aspect of distal phalanx of the index and little finger of the affected hand. Normal healthy patients with no signs and symptoms of carpal tunnel syndrome were recruited as controls and skin capacitance was measured in a similar fashion as the CTS group. Results. The CTS group consisted of 25 patients (18 female & 7 male) and 35 hands with an average age of 59.2 years (33-83 years). The mean symptom severity score was 2.80 (1.27-4.18; SD 0.82) and
The treatment of osteochondral lesions and osteoarthritis
remains an ongoing clinical challenge in orthopaedics. This review
examines the current research in the fields of cartilage regeneration,
osteochondral defect treatment, and biological joint resurfacing, and
reports on the results of clinical and pre-clinical studies. We
also report on novel treatment strategies and discuss their potential
promise or pitfalls. Current focus involves the use of a scaffold
providing mechanical support with the addition of chondrocytes or mesenchymal
stem cells (MSCs), or the use of cell homing to differentiate the
organism’s own endogenous cell sources into cartilage. This method
is usually performed with scaffolds that have been coated with a
chemotactic agent or with structures that support the sustained
release of growth factors or other chondroinductive agents. We also
discuss unique methods and designs for cell homing and scaffold
production, and improvements in biological joint resurfacing. There
have been a number of exciting new studies and techniques developed
that aim to repair or restore osteochondral lesions and to treat
larger defects or the entire articular surface. The concept of a
biological total joint replacement appears to have much potential. Cite this article:
We examined the mechanical properties of Vicryl (polyglactin 910) mesh Mesh fibres were visible at six weeks but had been completely resorbed by 12 weeks, with no evidence of chronic inflammation. The tendon-implant neoenthesis was predominantly an indirect type, with tendon attached to the bone-hydroxyapatite surface by perforating collagen fibres.
