Are the non-weight bearing guidelines for the after treatment of calcaneal fractures still decisive? A Dutch survey among orthopaedic and trauma surgeons.

PURPOSE: The current rehabilitation for patients with surgically treated displaced intra-articular calcaneal fractures (DIACFs) consists of non-weightbearing for 8-12 weeks. The purpose of the present survey was to investigate the current pre-, peri- and post-operative practices among Dutch foot and ankle surgeons. Moreover, it aims to analyze whether surgeons comply to the Arbeitsgemeinschaft für Osteosynthesefragen (AO) guidelines and which decision criteria were used in the determination of the start of weightbearing. METHODS: A survey was distributed among Dutch trauma and orthopaedic surgeons to determine the most common practices in postoperative weightbearing in patients with DIACFs. RESULTS: 75 surgeons responded to the survey. 33% of the respondents adhered to the AO guidelines. 4% of the respondents strictly followed non-weightbearing guidelines, while 96% interpret the AO guidelines or their local protocol freely, in any frequency. When respondents tended to deviate from the AO guidelines or local protocol, a good patients' compliance to therapy was expected. 83% of the respondents started weightbearing on the fracture, based on reported patient complaints. 87% of the respondents did not see any relation between early weightbearing and the occurrence of complications, including loosening of osteosynthesis materials. CONCLUSION: This study demonstrates that there is limited consensus on the rehabilitation for DIACFs. Moreover, it shows that most surgeons are inclined to interpret the current (AO) guideline or their own local protocol freely. New guidelines, supported with well-founded literature, could help surgeons in a more appropriate daily practice in weightbearing for the rehabilitation of calcaneal fractures.

Effectiveness of surgical treatments on healing of cartilage and function level in patients with osteochondral lesions of the tibial plafond: A systematic review.

BACKGROUND: Osteochondral lesions of the tibial plafond (OLTPs) occur less frequently than those of the talus, and treatment guidelines have not been determined. The aim of the current review was to evaluate the effectiveness of surgical treatments on the healing of cartilage and on function level, i.e. pain reduction, reduced swelling and improved joint range of motion, in patients with OLTPs. METHODS: A comprehensive literature search in PubMed/MEDLINE, Cochrane Database of Systematic Reviews and Google Scholar was performed up to December 2020. The outcome measures were healing of cartilage and function level. RESULTS: Four studies investigating treatment of OLTPs were included. Three studies investigated treatment by means of microfracture. One of these studies showed an osteochondral defect filling in 52.0% of patients. All three studies showed an improvement in function level. Antegrade drilling was evaluated in one study, showing contrasting results in two patients. One-step bone marrow-derived cell transplantation was evaluated in one study, showing an osteochondral defect filling in 68.0% of patients and improvements in patients' function level. CONCLUSIONS: Arthroscopic treatment of OLTPs by means of microfracture and bone marrow-derived cell transplantation (BMDCT) seem effective for the outcome at the patient's function level, while BMDCT showed more promising results regarding defect filling. However, this is based on the current available evidence with poor quality of methodology. Further research is of paramount importance to understand this injury and to evaluate the best treatments.

Medium-Term Patient-Reported Quality of Life and Activities of Daily Living in Surgically Treated Trauma Patients With Pelvic, Acetabular or Combined Pelvic and Acetabular Fractures in a Retrospective Single-Center Study.

OBJECTIVE: To gain more insights in the medium-term patient-reported quality of life (QoL), activities of daily living (ADL), and number of complications in trauma patients with an acetabular fracture (AF), a pelvic fracture (PF), and those with a surgically combined pelvic and AF (PAF). DESIGN: Retrospective single-center study. SETTING: Level I academic trauma center. PATIENTS/PARTICIPANTS: 51 trauma patients with PF, AF, or PAF who were surgically treated between 2014 and 2017. INTERVENTION: Open reduction and internal fixation. MAIN OUTCOME MEASUREMENTS: Primary outcome measures are patient-reported outcome questionnaire, which includes 2 items, the QoL, as measured with the Short Form-12, and the ADL, as measured with the Lower Extremity Functional Scale. The secondary outcome parameter was the occurrence of complications during a follow-up of at least 2 years. RESULTS: The mean physical component score (PCS) of the QoL (P = 0.03) and the ADL (P = 0.03) were significantly higher in patients with AF compared with patients with PF. The incidence of the overall postoperative complications did not significantly differ between the PF, AF, and PAF groups (P = 0.28). CONCLUSIONS: This study found that the PCS of the QoL and the ADL in surgically treated trauma patients with PF were significantly lower compared with patients with AF. No significant differences were found in overall complication rate between the PF, AF, and PAF groups. LEVEL OF EVIDENCE: Prognostic Level III.

Deep learning in fracture detection: a narrative review.

Artificial intelligence (AI) is a general term that implies the use of a computer to model intelligent behavior with minimal human intervention. AI, particularly deep learning, has recently made substantial strides in perception tasks allowing machines to better represent and interpret complex data. Deep learning is a subset of AI represented by the combination of artificial neuron layers. In the last years, deep learning has gained great momentum. In the field of orthopaedics and traumatology, some studies have been done using deep learning to detect fractures in radiographs. Deep learning studies to detect and classify fractures on computed tomography (CT) scans are even more limited. In this narrative review, we provide a brief overview of deep learning technology: we (1) describe the ways in which deep learning until now has been applied to fracture detection on radiographs and CT examinations; (2) discuss what value deep learning offers to this field; and finally (3) comment on future directions of this technology.

Long-term Patient-reported Quality of Life and Pain After a Multidisciplinary Clinical Pathway for Elderly Patients With Hip Fracture: A Retrospective Comparative Cohort Study.

INTRODUCTION: There is an increase in incidence of hip fractures in the ageing population. The implementation of multidisciplinary clinical pathways (MCP) has proven to be effective in improving the care for these frail patients, and MCP tends to be more effective than usual care (UC). The aim of this study was to analyze potential differences in patient-reported outcome among elderly patients with hip fractures who followed MCP versus those who followed UC. MATERIALS AND METHODS: This retrospective cohort study included patients aged 65 years or older with a low-energy hip fracture, who underwent surgery in the Maastricht University Medical Center, Maastricht, the Netherlands. Two cohorts were analyzed; the first one had patients who underwent UC in 2012 and the second one contained patients who followed MCP in 2015. Collected data regarded demographics, patient-reported outcomes (Short Form 12 [SF-12] and the Numeric Rating Scale [NRS] to measure pain), and patient outcome. RESULTS: This cohort study included 398 patients, 182 of them were included in the MCP group and 216 were in the UC group. No differences in gender, age, or American Society of Anesthesiologists classification were found between the groups. No significant differences were found in SF-12 and the NRS data between the MCP group and UC group. In the MCP group, significantly lower rates of postoperative complications were found than in the UC group, but mortality within 30 days and one year after the hip fracture was similar in both groups. DISCUSSION: Although the effects of hip fractures in the elderly on patient-reported outcome, pain and quality of life have been addressed in several recent studies, the effects of MCP on long-term outcome was unclear. CONCLUSION: A multidisciplinary clinical pathway approach for elderly patients with a hip fracture is associated with a reduced time to surgery and reduced postoperative complications, while no differences were found in quality of life, pain, or mortality.

Long-term functional outcome after a low-energy hip fracture in elderly patients.

BACKGROUND: The incidence of hip fractures is increasing. Elderly patients with a hip fracture frequently present with comorbidities, which are associated with higher mortality rates. Clinical studies regarding long-term functional outcome and mortality in hip fractures are rare. The aim of this study was to analyse the functional outcome and the mortality rate after a follow-up of 5 years in elderly patients with a hip fracture. MATERIALS AND METHODS: This combined retrospective and cross-sectional study included patients aged 65 years or older with a low energy hip fracture who underwent surgery in the Maastricht University Medical Center+, the Netherlands. Data such as demographics and mortality rates were retrospectively collected and functional outcome (i.e. mobility, pain, housing conditions and quality of life) was assessed by a questionnaire. RESULTS: Two hundred and sixteen patients were included in this study (mean age 82.2, SD ± 7.5). No significant differences were found in pain before hip fracture and after 1-year and 5-year follow-ups. Long-term functional outcome deteriorated after a hip fracture, with a significant increase in the use of walking aids (p < 0.001), a significant decrease of patients living in a private home (p < 0.001), and a low physical quality of life (SF-12 PCS = 27.1). The mortality incidences after 30-day, 1-year and 5-year follow-ups were 7.9%, 37.0% and 69.4%, respectively. CONCLUSION: Long-term functional outcome in elderly patients with hip fractures significantly deteriorated, with an increased dependency for mobility and housing conditions and a decreased physical quality of life. In addition, hip fractures are associated with high mortality rates at the 5-year follow-up. LEVEL OF EVIDENCE: Level III, a retrospective cohort study.

A protocol for permissive weight-bearing during allied health therapy in surgically treated fractures of the pelvis and lower extremities.

OBJECTIVE: To optimize rapid clinical recovery and restoration of function and functionality, permissive weight-bearing has been designed as a new aftercare mobilization regimen, within the upper boundary of the therapeutic bandwidth, yet safe enough to avoid overloading. The aim of the present paper is to describe a comprehensive protocol for permissive weight-bearing during allied health therapy and to report on the time to full weight-bearing, as well as the number of complications, in patients with surgically treated fractures of the pelvis and lower extremities undergoing permissive weight-bearing. PATIENTS AND METHODS: This study included surgically treated trauma patients with (peri)- or intra-articular fractures of the pelvis and lower extremities. A standardized permissive weight-bearing protocol was used for all patients. Time to full weight-bearing and number of complications were recorded. RESULTS: This study included 150 patients, 69% male, with a median age of 48 years (interquartile range (IQR) 33.0, 57.0). The median time to full weight bearing was 12.0 weeks (IQR 6.8, 19.2). The complication rate during rehabilitation was 10%. CONCLUSION: The permissive weight-bearing protocol, as described, might be beneficial and has potential to be implemented in trauma patients with surgically treated (peri)- or intra-articular fractures of the pelvis and lower extremities.

Permissive weight bearing in trauma patients with fracture of the lower extremities: prospective multicenter comparative cohort study.

BACKGROUND: The standard aftercare treatment in surgically treated trauma patients with fractures around or in a joint, known as (peri)- or intra-articular fractures of the lower extremities, is either non-weight bearing or partial weight bearing. We have developed an early permissive weight bearing post-surgery rehabilitation protocol in surgically treated patients with fractures of the lower extremities. In this proposal we want to compare our early permissive weight bearing protocol to the existing current non-weight bearing guidelines in a prospective comparative cohort study. METHODS/DESIGN: The study is a prospective multicenter comparative cohort study in which two rehabilitation aftercare treatments will be contrasted, i.e. permissive weight bearing and non-weight bearing according to the AO-guideline. The study population consists of patients with a surgically treated fracture of the pelvis/acetabulum or a surgically treated (peri)- or intra-articular fracture of the lower extremities. The inclusion period is 12 months. The duration of follow up is 6 months, with measurements taken at baseline, 2,6,12 and 26 weeks post-surgery. PRIMARY OUTCOME MEASURE: ADL with Lower Extremity Functional Scale. Outcome variables for compliance, as measured with an insole pressure measurement system, encompass peak load and step duration. DISCUSSION: This study will investigate the (cost-) effectiveness of a permissive weight bearing aftercare protocol. The results will provide evidence whether a permissive weight bearing protocol is more effective than the current non-weight bearing protocol. TRIAL REGISTRATION: The study is registered in the Dutch Trial Register ( NTR6077 ). Date of registration: 01-09-2016.
