A Review on the Use of Artificial Intelligence in Fracture Detection.

Artificial intelligence (AI) simulates intelligent behavior using computers with minimum human intervention. Recent advances in AI, especially deep learning, have made significant progress in perceptual operations, enabling computers to convey and comprehend complicated input more accurately. Worldwide, fractures affect people of all ages and in all regions of the planet. One of the most prevalent causes of inaccurate diagnosis and medical lawsuits is overlooked fractures on radiographs taken in the emergency room, which can range from 2% to 9%. The workforce will soon be under a great deal of strain due to the growing demand for fracture detection on multiple imaging modalities. A dearth of radiologists worsens this rise in demand as a result of a delay in hiring and a significant percentage of radiologists close to retirement. Additionally, the process of interpreting diagnostic images can sometimes be challenging and tedious. Integrating orthopedic radio-diagnosis with AI presents a promising solution to these problems. There has recently been a noticeable rise in the application of deep learning techniques, namely convolutional neural networks (CNNs), in medical imaging. In the field of orthopedic trauma, CNNs are being documented to operate at the proficiency of expert orthopedic surgeons and radiologists in the identification and categorization of fractures. CNNs can analyze vast amounts of data at a rate that surpasses that of human observations. In this review, we discuss the use of deep learning methods in fracture detection and classification, the integration of AI with various imaging modalities, and the benefits and disadvantages of integrating AI with radio-diagnostics.

Utilizing an antibiotic-eluting articulated cemented spacer in the two-stage management of infected total hip arthroplasty: a technical note.

Two-stage revision is generally preferred to eradicate chronic periprosthetic infections after total hip arthroplasty (THA) because of its good infection control and promising results. During two-stage revision, a temporary antibiotic-impregnated cement spacer was initially used for the local delivery of antibiotics, thereby reducing the risk of infection recurrence. Many researchers have reported various techniques for fabricating cemented spacers; however, there is no established standard technique. We share our cost-effective and easily reproducible technique for creating an articulated cemented spacer for managing infected THA.

Intraoperative Foot Positioning During Percutaneous Calcaneal Fixation: A Technical Note.

Percutaneous screw fixation is a good modality for operative management of extra-articular and some intra-articular fractures of the calcaneum amenable to closed reduction. Tongue-type calcaneal fractures with a dislocated posterior facet are usually treated with percutaneous fixation. When treating calcaneal fractures with substantial soft tissue compromise, particularly open fractures, percutaneous reduction techniques are crucial. They also provide patients with local or systemic contraindications to open reduction with a therapeutic option. We describe the intraoperative positioning of the foot using a lithotomy stirrup during percutaneous fixation of the calcaneal fractures with minimum manipulation of the foot and C-arm and consistent imaging.

Postmenopausal Osteoporosis: A Literature Review.

A substantial proportion of the population of females in India falls in the perimenopausal and postmenopausal age groups. One of the complications associated with older age in women is the weakening of bones and the fall in bone mineral density (BMD). This has a severe debilitating consequence in a woman's life and leads to reduced quality of life along with a greater incidence of fractures. If the fracture involves the hip or the vertebrae, it can cause immobility and be devastating. Postmenopausal osteoporosis is linked with the deficiency of estrogen that occurs with the cessation of the function of the ovaries as age progresses. The function of estrogen in the bone remodeling process is very well understood after years of research; estrogen plays a part in both the formation of bone as well as the prevention of the resorption of bone. A diagnosis can be made by dual-energy X-ray absorptiometry (DEXA). It is the gold standard and can spot low bone density at particular sites. The treatment options are selected according to the severity and rate of progression and factors pertaining to each patient. All postmenopausal women should be made aware of this disorder, and they should be encouraged to cultivate a healthy lifestyle through the implementation of a proper diet and inculcation of a regular exercise routine. Smoking and drinking alcohol should be limited, and calcium and vitamin D supplementation should be started in all women of the postmenopausal age group with or without osteoporosis. In patients who have been diagnosed with the disorder, pharmacological intervention is done. Drugs should be selected based on their side effects and contradictions. Follow-up is essential, and patient compliance should be carefully monitored. This article attempts to review the existing literature on this very prevalent disorder to spread awareness about it so that all postmenopausal women can take the necessary steps to prevent the weakening of their bones, and deal with its progression.

Tibia Nailing Using Modular Stand: A Technical Note.

Interlocking nailing is a well-established procedure for managing unstable tibial shaft fractures. Closed reduction and internal fixation of the tibial shaft fractures require ease of intraoperative positioning, maneuvering, and biplane imaging. We describe the use of an innovative modular tibia-nailing stand, which greatly enhances the ergonomics of the tibia nailing procedure.

The Utility of Supracutaneous Plating in the Staged Management of Compound Distal Femur Fracture: A Case Report.

The aim of this report is to draw attention to the use of a vilipend technique 'supracutaneous plating' in the management of compound distal femur fractures. Treatment of compound fractures of the distal femur with bone defects and microbial infection remains a challenging task for orthopaedic trauma surgeons. In this case report, we share our experience with the use of the locking distal femoral plate as an external fixator for the staged management of a compound infected distal femur fracture in a 22-year-old male patient. Staged procedures with proper planning give excellent results for infected fractures. Supracutaneous plating can be a viable and patient-friendly alternative in the staged management of compound distal femur fractures instead of the conventional external fixators.

The Importance of Prompt Management of Morel-Lavallée Lesions.

The Morel-Lavallée lesion (MLL) is a closed soft-tissue injury that is frequently associated with high-intensity trauma. The thigh, hip, and pelvic regions are the most typically affected regions. It is critical to recognize and treat an MLL as soon as possible because it is often neglected or its identification is delayed because of other distracting injuries in a polytrauma patient. Bacterial colonization of these closed soft-tissue wounds can result in an increased risk of perioperative and postoperative infection. Magnetic resonance imaging has recently been used to define and grade these lesions. To reduce the dangers of these situations, clinical suspicion and on-the-spot identification of these lesions are essential. Here, we report an operated case of fracture shaft femur associated with MLLs and discuss the diagnostic and surgical approaches.

Crescent Fracture of the Pelvis: A Case Report.

Crescent fractures are a rare type of pelvic injury. They result from a lateral compression force and are rotationally unstable. The following is a case of a young male who suffered a crescent fracture on the right side of the pelvis and was treated for the same. These fractures, being rare and complex, need to be managed in accordance with other injuries sustained by the patient and also need fixation for a better functional outcome.

Impact of medial open-wedge high tibial osteotomy for medial compartment osteoarthritis of the knee.

BACKGROUND: Most populations worldwide, who are used to squatting and sitting cross-legged for their activities of daily living, largely comprise the lower socioeconomic strata, thus making them candidates for exclusion for total knee arthroplasty. Proximal/high tibial osteotomy (HTO) is a preferred strategy for clinically symptomatic osteoarthritis (OA) with genu varum due to painful medial compartment OA which is not amenable to conservative measures. AIM: To evaluate the outcomes of medial open-wedge HTO along with autologous bone grafting and buttress plate for the treatment of genu varum due to OA of the knee in a rural population of central India. METHODS: A total of 65 knees in 56 patients with a mean age of 58.22 ± 5.63 years with genu varum due to intractable painful knee OA were treated with medial open-wedge HTO along with autologous bone grafting and buttress plate osteosynthesis from June 2015 to May 2018. The mean preoperative radiological angle of genu varum was 13.4°. Clinical outcomes were assessed by the range of movement, knee scores, pain scores, and functional scores. Radiographic studies were performed preoperatively and at regular intervals during the follow-up period. RESULTS: All patients reported pain relief immediately after the osteotomy and during the long-term analysis covering between one to three years. The genu varum angle was overcorrected to approximately four degrees in all patients. There was a loss of reduction by approximately three degrees in all patients at around six weeks postoperatively. Preoperative knee movements were restored in all patients. No major perioperative complications were noted during surgery and postoperative follow-up and the clinical scores were significantly improved during the final analysis which revealed good pain relief. CONCLUSION: Medial open-wedge HTO is a reliable, safe, practical, physiological, and feasible treatment for populations who are used to increased activity in their occupation and lifestyle and is associated with excellent short-term and long-term results for OA in genu varum knees.

Hip Arthroscopy for Femoroacetabular Impingement and Concomitant Labral Tears: A Minimum 2-Year Follow-Up Study.

PURPOSE: The present study investigated the minimum 2-year outcomes of hip arthroscopy for femoroacetabular impingement (FAI) and concomitant labral tears in Asian patients. METHODS: Patients who underwent hip arthroscopy for both FAI and concomitant labral tears between January 2012 and December 2017 were included. Patients with hip osteoarthritis of Tönnis grade ≥2, previous hip surgery, or followed for less than 2 years were excluded. Clinical assessments were performed using the modified Harris Hip Score, Western Ontario and McMaster Universities Osteoarthritis Index, and the rates of achieving threshold values of the minimal clinically important difference and patient acceptable symptomatic state at the latest follow-up. Plain radiographs were acquired pre- and postoperatively for radiologic assessments. RESULTS: A total of 73 patients (90 hips, 58 male, 15 female; mean age 34.4 years) who underwent hip arthroscopy for FAI and concomitant labral tears were enrolled. Forty-three hips (47.8%) had cam-type, 7 (7.8%) had pincer-type, and 40 (44.4%) had mixed-type FAI. The mean follow-up duration was 5.2 years. In cam- and mixed-type FAI hips, the mean α angle significantly decreased from 66.7 ± 8.28° preoperatively to 44.9 ± 3.78° postoperatively (95% confidence interval [CI] 19.6°-22.8°; P < .001). The mean modified Harris Hip Score and Western Ontario and McMaster Universities Osteoarthritis Index increased from 74.8 ± 13.2 and 75 ± 12.7 preoperatively to 93 ± 8.1 (95% CI 15.4-20.9; P = .001) and 89.4 ± 8.4 postoperatively (95% CI 11.8-17; P = .001), respectively. Seventy-four hips (82.2%) crossed the minimal clinically important difference, and 85 hips (94.4%) had achieved the patient acceptable symptomatic state. There were 2 cases of pudendal nerve palsy and 1 case of sciatic nerve palsy. No additional surgeries were required. CONCLUSIONS: Hip arthroscopy can be an effective treatment for FAI and concomitant labral tears in Asian patients as demonstrated in this study, with improved PRO scores and reoperation rates. Longer-term studies with larger cohorts are necessary. LEVEL OF EVIDENCE: Level IV, case series.

Multiple drilling and multiple matchstick-like bone allografts for large osteonecrotic lesions in the femoral head: an average 3-year follow-up study.

INTRODUCTION: We aimed to present the clinical outcomes of multiple drilling and multiple matchstick-like bone allograft for large osteonecrotic lesions of the femoral head as a joint-preserving surgery. MATERIALS AND METHODS: Between March 2014 and March 2018, 57 patients (77 hips) who underwent multiple drilling and multiple matchstick-like bone allograft for large lesions (≥ 30%) in osteonecrosis of the femoral head (ONFH) were included. Harris hip scores (HHS) and Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) were obtained preoperatively and at the latest follow-up. Plain radiographs were obtained every 3 months. Femoral head collapse ≥ 2 mm was defined as a radiological failure, and conversion to total hip arthroplasty (THA) was regarded as a clinical failure. RESULTS: After exclusion of 5 patients (5 hips) who lost to follow-up, 52 patients (34 men, 18 women; 72 hips) were finally enrolled. The mean follow-up period was 3.4 (range 2-4.5) years. Nineteen hips (28.4%) required conversion to THA at a mean of 21.6 (range 6-42) months postoperatively. In the remaining 53 hips (71.6%) with clinical success, the mean HHS and WOMAC improved from 63 and 31.3 preoperatively to 80.6 and 16.3 at the final follow-up, respectively (p < 0.001). Radiological failure occurred in four hips (6%). The overall failure rate was 31.9% (23/72 hips), and the mean survival duration until failure was 21.2 months (6-42 months). The lesion size, lesion location, and the use of corticosteroids as the cause of ONFH were associated with clinical failure. CONCLUSION: Multiple drilling and multiple matchstick-like bone allograft may be a useful treatment option for alleviating the symptoms in ONFH patients with large lesions who want to preserve their hips.

Clinical Outcomes of an Initial 3-month Trial of Conservative Treatment for Femoroacetabular Impingement.

BACKGROUND: Femoroacetabular impingement (FAI) can be managed either conservatively or by a surgical correction of the deformity causing impingement. However, there is insufficient evidence to justify an immediate surgical treatment in all symptomatic patients, and the role of a nonoperative treatment is unclear. This study evaluates the role of conservative treatment for FAI. MATERIALS AND METHODS: 87 patients (102 hips) diagnosed as FAI between January 2011 and May 2012 were included in this retrospective study. All patients underwent an initial 3-month conservative treatment followed by arthroscopic hip surgery if symptoms did not improve. Clinical outcome scores (modified Harris Hip Score, nonarthritic hip score, and Western Ontario and McMaster Universities Arthritis Index) were evaluated at baseline and at the end of followup, and scores were compared between the nonsurgical and surgical groups. RESULTS: The final analysis included 83 patients (55 men, 28 women; 97 hips) because four patients were lost to followup. The average age was 45.1 years and 14 patients had bilateral symptomatic FAI. After an initial conservative treatment averaging 27.5 months (range 24-36 months), 53 hips (54.6%) could perform normal daily activities. The nonsurgical group had significant improvements in all clinical scores at the end of followup (P < 0.001). Forty four hips (45.4%) were unresponsive to conservative treatment and underwent arthroscopic hip surgery with subsequent significant improvements in clinical scores (P < 0.001). At the end of followup, there were no significant differences in clinical scores between the two groups. CONCLUSION: An initial trial of conservative treatment of sufficient length should be considered for FAI patients before surgical intervention.
