Locally aggressive monostotic fibrous dysplasia of the cervical spine mimicking malignancy: a case report and literature review
No full textWe report the case of a 30-year-old woman with histologically proven monostotic fibrous dysplasia of C2 revealed by a pathological fracture of the odontoid process. Radiological investigations showed a ground-glass mineralization of the vertebral body, a centimetric lytic area with poorly defined margins involving the inferior part of the vertebral body and inferior endplate and a fracture through an osteolytic area in the base of the odontoid process.
Owing to the vertebral instability, a surgical procedure combining C0–C5 fixation and posterior bone grafting was performed. The surgical biopsy was inconclusive and pathological confirmation was finally obtained through a percutaneous needle biopsy under fluoroscopic guidance. At 26-month follow-up, the patient still experienced mild persistent cervical posterior neck pain and stiffness possibly related to a C5–6 laxity below the intervertebral fixation.
This case combines three radiological findings, which are unusual in fibrous dysplasia: monostotic presentation involving the spine, some aggressive radiographic features, and a pathological fracture
Current practice and preferences to management of equinus in children with ambulatory cerebral palsy: A survey of orthopedic surgeons
No full textIntroduction: The consensus among orthopedic surgeons on the management of equinus deformity in cerebral palsy (CP) children has not been reported previously despite being a prevalent deformity. The goals of this study were to examine the orthopedic surgeons’ current practice regarding the management of equinus deformity in children with ambulatory CP, and analyze variations in current practice between general orthopedic and pediatric orthopedic surgeons.
Methods: We implemented a brief cross-sectional self-reported questionnaire that addressed the areas of clinical examination and decision-making skills of management of equinus deformity in CP children. We targeted a convenience sample of 400 participants. Surgeons that provided complete responses to the questionnaire were 223 with a response rate of 56%, of which 123 (55%) were general orthopedic surgeons, whereas 100 (45%) were pediatric orthopedic surgeons. The target population consisted of orthopedic surgeons who were further sub-classified in accordance with practice age, general versus pediatric, and exposure to children’s orthopedics during the last three years of their practice. For analytical statistics, the Chi-Square test and Fisher’s exact test were used to examine the relationship between two qualitative variables.
Results: The overall clinical practice preferences of all survey participants were unimpressive with discordant survey responses. Pediatric orthopedic surgeons generally demonstrated a statistically significant difference regarding clinical assessment skill items of the survey, in contrast to general orthopedic surgeons. However, we found no differences between pediatric orthopedic and general orthopedic surgeons regarding most of the decision-making/knowledge items.
Discussion: Generally, there are insufficient clinical practice trends of both general and pediatric orthopedic surgeons regarding equinus treatment in CP children. This may indicate a knowledge–practice gap with potential risks to CP children undergoing surgery for equinus. There is a need for a more competent exposure to CP in orthopedic surgeons’ educational curricula and an updated health referral system
The use of anterior subcutaneous internal fixation (INFIX) for treatment of pelvic ring injuries in major trauma patients, complications and outcomes
No full textPurpose: Pelvic anterior internal fixators (INFIX) are a relatively new alternative in the treatment of unstable pelvic fractures. The authors wanted to review the use of complications and outcomes of this method of pelvic fixation at our institution.
Method: Patients over the age of 18 who had an INFIX used in treatment of their pelvic ring injury were identified. Patient demographics, fracture type, injury severity score, morbidity, complications and time until removal were recorded. All available patients were followed up following the removal of the INFIX and completed an Iowa Pelvic Score (IPS) at this time.
Results and Discussion: 24 patients (19 male) with a mean age of 38.5 (range 18–71) met the inclusion criteria with an average injury severity score of 29.8 (10–66). The most common complication following insertion was a lateral femoral cutaneous nerve (LFCN) injury, which occurred in 11 patients (bilaterally in two), 6 patients (25%) had ongoing numbness 6 months post removal. Two patients had an infection, one of which prompted the removal of the INFIX. One INFIX was removed for implant failure. All other removals were planned electively. Heterotopic ossification was noted to have occurred in five cases. The mean IPS following removal of the INFIX was 79.2 (52–100). INFIX is a safe and successful treatment for unstable pelvic ring injuries. Overall, patients tolerate the INFIX well with good outcome scores. The main concern being the high rate of LFCN injuries, although many resolved after removal of the INFIX
A proposed radiological classification system of Hoffa’s fracture based on fracture configuration and consequent optimal treatment strategy along with the review of literature
No full textBackground: Coronal fractures of distal end femur, referred as Hoffa’s fracture are not uncommon, yet easily missed injuries lacking proper classification system and consensus for ideal treatment. While most trauma surgeons adopt different strategies based on the fracture configuration and their own experience, there are no set ways to classify these based on the most appropriate treatment strategy. Methods: Thirty cases of Hoffa fracture from tertiary care centres were studied for the fracture pattern, fragment size, comminution and possible variations to formulate a radiological classification and treatment guidelines. Additionally, a literature search was used to analyze 77 case studies based on Hoffa fracture to find out the common fracture patterns and treatment modalities adopted for varying fracture patterns in these studies. Six independent observers participated in testing the inter-observer reliability of the proposed classification. Results: A new proposed radiological classification for Hoffa fracture consists of four main types. Type 1 is with fracture fragment >2.5 cm, Type 2 with fragment <2.5 cm, Type 3 is comminuted fracture, Type 4 are subdivided as Type 4a – Anterior, Type 4b – Bicondylar, Type 4c – Osteochondral type and Type 4d – With supracondylar extension. Optimum treatment modality depends on the type of Hoffa’s fracture and has been suggested in the study. Interobserver reliability demonstrated that overall agreement was 0.907692 with a fixed marginal Kappa of 0.881067 and free Marginal Kappa at 0.892308. Intra-observer reliability test for the classification system showed a strong Kappa value of +1.0. Conclusion: The new suggested classification helps identify different types of Hoffa’s fracture. This is likely to help decide optimal surgical treatment depending on the nature of the injury. The classification system has high inter and intra-observer reliability that enables its universal applicability
Periprosthetic joint infections after total hip replacement: an algorithmic approach
No full textAn algorithm for managing periprosthetic joint infections (PJIs) after total hip replacement (THR) surgery using a multidisciplinary approach and a clearly defined protocol may improve infection eradication rates. In this article, we present an algorithm for the management of different types of PJIs including the acutely infected cemented and cementless THRs where the components are well-fixed postoperatively and when the infection is secondary to haematogenous spread in previously well-functioning and well-fixed implants. For chronic PJIs where the components are often loose, the standard treatment includes a two-stage revision procedure. However, in a highly selected subset of patients, a single-stage approach has been utilised with high rates of eradicating infections
The clinical outcomes of total femur prosthesis in patients with musculoskeletal tumors
No full textIntroduction: Reconstruction using a total femur prosthesis (TFP) remains a challenging procedure in musculoskeletal tumor surgery. The purpose of this study was to show the clinical outcomes of total femur replacement (TFR) in our institute.
Methods: Nine patients underwent reconstruction with a TFP after the wide resection of malignant bone and soft-tissue tumors of the femur between January 2003 and April 2014. The mean age of the patients at the time of TFR was 47.5 years, and the mean follow-up period was 52.9 months. The histological diagnoses were as follows: bone sarcoma (n = 4), soft-tissue sarcoma invading the femoral bones (n = 4), and metastatic bone tumor (n = 1).
Results: The oncological outcomes were as follows: three patients achieved continuous disease free, two patients were alive with disease, and four patients died from disease. The 3- and 5-year overall survival rates were 88.9% and 55.6%, respectively. The rate of the overall survival in patients with primary bone tumors (100% at 5 years) was significantly better than that in patients with primary soft tissue sarcomas (0% at 5 years) (p = 0.015). A deep infection occurred postoperatively in one patient, but the patient was successfully treated with surgical debridement and revision surgery. There were no patients who showed dislocation or aseptic loosening. The mean Musculo-Skeletal Tumor Society functional score was 58.5% (46.7–80.0), with scores of 65.5% in patients with a primary bone tumor and 50.8% in those with a primary soft-tissue sarcoma.
Discussion: In the present study, the patients who underwent TFR due to bone invasion by soft tissue sarcoma had a worse prognosis than the bone sarcoma patients
Orthopaedic research in low-income countries: A bibliometric analysis of the current literature
No full textBackground: To perform a bibliometric analysis and quantify the amount of orthopaedic and trauma literature published from low-income countries (LICs).
Methods and methods: The Web of Science database was utilised to identify all indexed orthopaedic journals. All articles published in the 76 orthopaedics journals over the last 10 years were reviewed, to determine their geographic origin.
Results: A total of 131 454 articles were published across 76 orthopaedic journals over the last 10 years. Of these, 132 (0.1%) were published from LICs and 3515 (2.7%) were published from lower middle-income countries (LMICs); 85.7% (n = 112 716) of published orthopaedic research was undertaken in a high-income setting. The majority of the studies (n = 90, 74.4%) presented level IV evidence. Only 7.4% (n = 9) were high-quality evidence (level I or II). Additionally, the majority of research (74 articles, 56%) was published in partnership with high-income countries (HICs).
Conclusions: There is a stark mismatch between the publication of scientific reports on orthopaedic research and the geographical areas of greatest clinical need. We believe there is an urgent need for orthopaedic research to be carried out in low-income settings to guide treatment and improve outcomes, rather than assuming that evidence from high-income settings will translate into this environment
Femoral head disengagement from Accolade femoral stem in MOM Arthroplasty: a case study and literature review
No full textBackground: Metal on Metal Hip arthroplasty was commonly used until the last decade. However Hip Arthroplasty registries of many countries showed increased revision rates of MOM Hips – these high rates of revision caused by trunnionosis, adverse tissue reactions (ALTRs) and Pseudotumor formation.
The Case: Our Case is 73 years old gentleman who had left MOM THR in 2008, and was doing fine till the beginning of 2018 when his left leg stuck while getting out of the car. Despite he heard the pop and his leg was shortened and externally rotated, but he was still walking on it for a while. On reviewing him in our orthopedic clinic and after getting the CT-scan showed that he had dislocated femoral head from the stem
The antibacterial effect of sonication and its potential medical application
No full textIntroduction: Recent applications of ultrasonic probes include cataract removal and tennis elbow treatment. Early data support the use of ultrasonic probe debridement in the treatment of recalcitrant diabetic foot ulcers. No data are available concerning the potential antibacterial properties of the clinical grade, lower energy ultrasound probes. We investigated the effect of a clinically available ultrasonic debridement probe with respect to bacterial viability.
Methods: A commercially available Tenex sonication machine with a Tx1 probe was used for this study. Three bacterial strains, aerobic and anaerobic, were investigated, G-negative (Porphyromonas gingivalis) and G-positive bacteria (Staphylococcus aureus and Streptococcus gordonii). These bacteria were cultured and tested with sonication for varying lengths of time (10, 30, 60, and 120 s). The tested bacterial samples were plated, the number of colonies on each plate counted, and the anti-bacterial effect was calculated. Statistical analysis was conducted using a one-way analysis of variance.
Results: Sonication exhibited a significant time-dependent antibacterial effect. Statistically significant anti-bacterial effect was observed in all three species tested. When comparing the kill rate between the control and 120 s of sonication; S. gordonii had a 34% kill rate, S. aureus had a 60% kill rate, and P. gingivalis had a 64% kill rate. When comparing control to all of the time intervals tested, S. aureus kill rate was statistically significant at all times, S. gordonii was statistically significant at all times above 10 s, and P. gingivalis was only statistically significant at 120 s.
Conclusion: This study demonstrates that a clinically available ultrasonic probe has an antibacterial effect against a wide spectrum of gram-positive, gram-negative, aerobic and anaerobic bacterial species. This may partially explain the dramatic healing of long-standing recalcitrant diabetic ulcers debrided with this device and may have a place in treating pathologies with bacterial mechanisms
Radiological, functional, and anatomical outcome in patients with osteoarthritic knee undergoing high tibial osteotomy
No full textObjective: To determine the radiological, functional, and anatomical outcome in patients with osteoarthritic knee undergoing high tibial osteotomy (HTO).
Design of study: Descriptive case series.
Study duration and settings: The present study was a descriptive case series carried out at the Orthopedic Departments of District Head Quarter Hospital Faisalabad affiliated with Faisalabad Medical University, Faisalabad from Jan 2014 to March 2018.
Methodology: This study involved 40 patients of both genders, aged between 40 and 65 years having advanced degenerative disease of knee limited to medial compartment of joint. These patients were treated by medial open wedge high tibial osteotomy (OWHTO) and outcome was evaluated after 5 years of surgery in terms of radiological knee mechanics, functional outcome scores, and arthroscopic evidence of cartilage regeneration in the medial compartment. A signed written consent was taken from every patient.
Findings: There was a female predominance with a male-to-female ratio of 1:4. The mean age of the patients was 53.2 ± 6.9 years. The values of the radiographic parameters significantly changed from pre-operative condition after HTO; mechanical tibiofemoral angle [MTFA, (−8.1 ± 1.2° vs. 2.5 ± 1.2°; p-value < 0.0001)], tibial plateau inclination [TPI, (5.3 ± 1.1° vs. 3.4 ± 1.1°; p-value < 0.0001)], knee joint line orientation relative to the ground [G-KJLO, (0.3 ± 0.1° vs. 4.6 ± 1.5°; p-value < 0.0001)], and ankle joint line orientation relative to the ground [G-AJLO (8.3 ± 3.2° vs. 2.3 ± 1.7°; p-value < 0.0001)]. There was significant improvement in patient’s functional status; KOOS-ADL score (45.5 ± 7.8 vs. 73.7 ± 8.6; p-value < 0.0001), International Knee Documentation Committee (IKDC) score (42.4 ± 6.9 vs. 68.5 ± 12.7; p-value < 0.0001), International Knee Society (IKS) score (149.4 ± 11.9 vs. 179.4 ± 10.2; p-value < 0.0001), Knee Society Score [KSS, (54.2 ± 5.6 vs. 69.7 ± 12.7; p-value < 0.0001)], and Hospital for Special Surgery [HSS, (50.8 ± 3.3 vs. 64.8 ± 10.7; p-value < 0.0001)]. 42.5% patients showed excellent regeneration of femoral and 30.0% patients showed excellent regeneration of tibial cartilage in the medial compartment.
Conclusion: By significantly alternating the knee biomechanics, HTO was found to unload the medial compartment leading to regeneration of the articular cartilage and significant improvement in patient’s symptoms and quality of life. It is therefore recommended in the management of patients with arthritic changes limited to medial compartment only
