Isolated Tear of the Vastus Lateralis Tendon: A Rare Case Managed Conservatively.

Introduction: Isolated ruptures of the vastus lateralis (VL) tendon are exceptionally rare, with few reported cases in the orthopedic literature. This case report sheds light on non-surgical management for partial VL tendon ruptures, providing insight into an alternative treatment pathway that avoids surgical intervention. Case Report: A 27-year-old Caucasian male experienced a partial, isolated rupture of the VL tendon after a minor fall. The injury was confirmed through magnetic resonance imaging at the lateral patellar insertion. The patient displayed no knee instability and was treated conservatively with platelet-poor plasma injections, a hinged knee brace, and targeted physiotherapy. Conclusion: This case illustrates that conservative treatment can be effective for patients with isolated partial VL tendon ruptures, particularly when knee stability is maintained. The patient achieved full activity recovery within 6 months, highlighting the potential of non-surgical options to provide successful outcomes in similar cases. This report enriches our understanding of tendon injury management and emphasizes the clinical viability of conservative strategies, potentially influencing treatment decisions for similar orthopedic injuries.

Delayed onset of Corynebacterium simulans infection following open reduction and internal fixation of a trimalleolar fracture.

Surgical site infections (SSIs) following open reduction and internal fixation (ORIF) of ankle fractures can lead to significant disability. This case report emphasizes a unique instance of SSI caused by Corynebacterium simulans, following ORIF of a trimalleolar ankle fracture in a 55-year-old female patient. To our knowledge, this is the first reported case of C. simulans infection after ORIF in the literature. The pathogen was detected after surgical debridement, removal and sonication of the hardware, and identified through matrix assisted laser desorption/ionization-time of flight mass spectrometry (MALDI-TOF MS) and 16S rRNA gene sequencing. Specific intravenous antibiotic regimen was administered for a total duration of 4 weeks. During the 12th month follow-up, the patient presented no signs of infection and an excellent clinical outcome. This case report underscores the need for alertness regarding atypical pathogens in postoperative complications and the critical role of precise microbial diagnosis in managing rare orthopaedic infections.

Giant Lipoma in the Index Finger of a 60-Year-Old Patient: A Rare Case Report and Review of the Literature.

Introduction: Lipomas are the most common benign mesenchymal tumors found on the head, neck, shoulder, and back, but they are rarely encountered in the fingers, constituting <1% of such tumors. Case Report: This case report presents an exceptional location of a giant lipoma on the proximal phalanx of a 60-year-old Caucasian male's rightindex finger, alongside a literature review that identified 20 similar cases. The patient, with no significant health issues, reported that the growthhad been asymptomatic for 2 years before seeking consultation due to aesthetic concerns and impaired finger extension. Diagnostic imaging, including magnetic resonance imaging preoperatively, and histopathological analysis after surgical excision confirmed the diagnosis of a maturelipoma. Conclusion: This case contributes to the scarce documentation on finger lipomas, emphasizing the diagnostic challenges they present and the effectiveness of surgical removal in averting recurrence. It also highlights the unusual demographic occurrence, given the predominant presentation in middle-aged females, and underscores the necessity of considering lipomas in the differential diagnosis of finger masses. The literature review expands on the rarity of this condition, providing an analysis of 20 other cases, thereby enriching the understanding of lipoma manifestations in rare locations.

Patella Fracture After Total Knee Arthroplasty: A Review.

The management and underlying causes of patellar periprosthetic fractures (PPF) after total knee arthroplasty (TKA) constitute an issue of growing importance given the rising frequency of these procedures. Patella periprosthetic fractures, though relatively rare, pose significant challenges and are a frequent indication for revision surgeries. Despite a decrease in overall incidence, PPFs remain the second most common type of periprosthetic fractures after TKA. Several factors have been identified and associated with patient-specific factors, surgical technique errors, and implant-related causes. Currently extensor apparatus integrity, bone stock, and component loosening are the major concerns and indications for the selective treatment approach. In this study, a thorough review of the existing literature was performed summarizing the epidemiology, clinical manifestation, treatment approach, and functional outcome of PPF. This review aims to underline the significance of such predisposing factors, point out the severity of PPF, and offer insights into the optimal intra- and post-operative management of the patella.

Screw Fixation as the Primary and Definitive Treatment of an Isolated Uncommon Fracture of the Anterior Margin of the Distal Tibia.

Tibial plafond fractures constitute one of the most challenging fracture types while they are commonly associated with soft tissue damage and severe bone comminution. We present the clinical outcomes of screw fixation as the initial and definitive treatment of an isolated uncommon fracture of the anterior margin of the distal tibia. This is a case of an uncommon type of fracture of the distal tibia. The patient underwent a successful screw fixation and the fracture healed in three months. There was no bone and soft tissue infection. Sixteen months after the injury, an excellent function of the ankle joint was noted. Although fractures of the anterior margin of the distal tibia are uncommon high-energy injuries, uneventful healing with very good functional results can be achieved with screw fixation as the initial and definitive treatment.

Isolated Avulsion Fracture of the Lesser Trochanter in an Adolescent: A Case Report and Review of the Literature.

Avulsion fractures of the lesser or greater trochanter or the iliac crest are uncommon injuries in adolescents. The anterior superior iliac spine, ischium, and anterior inferior iliac spine are the most frequently affected sites. We report a rare case of a 14-year-old boy who sustained an avulsion fracture of the lesser trochanter while playing soccer. No malignancy or associated metabolic bone disease was detected. Conservative treatment was suggested, consisting of a non-weight-bearing period and analgesics. Routine follow-up was performed at one, three, and six months after the injury. Radiographs were utilized to confirm fracture healing. Full recovery and return to a pre-injury functional level were observed at six months. Within this timeframe, a thorough literature review is performed.

Cervical Spinal Epidural Abscess: Diagnosis, Treatment, and Outcomes: A Case Series and a Literature Review.

Although recent diagnostic and management methods have improved the prognosis of cervical epidural abscesses, morbidity and mortality remain significant. The purpose of our study is to define the clinical presentation of cervical spinal epidural abscess, to determine the early clinical outcome of surgical treatment, and to identify the most effective diagnostic and treatment approaches. Additionally, we analyzed studies regarding cervical epidural abscesses and performed a review of the literature. In this study, four patients with spinal epidural abscess were included. There were three men and one woman with a mean age of 53 years. Three patients presented with motor deficits, and one patient was diagnosed incidentally through spinal imaging. All the patients had fever, and blood cultures were positive. Staphylococcus aureus was the most common organism cultured from abscesses. All patients underwent a surgical procedure, and three patients recovered their normal neurological functions, but one remained with mild neurological disability that was resolved two years postoperatively. The mean follow-up period was 12 months, and no deaths occurred in this series. Furthermore, we identified 85 studies in the literature review and extracted data regarding the diagnosis and management of these patients. The timely detection and effective management of this condition are essential for minimizing its associated morbidity and mortality.

Isolated complete rupture of distal biceps femoris tendon following a motor vehicle accident: A case report and review of the literature.

Isolated complete ruptures of the distal biceps femoris tendon are rare injuries. To our knowledge, very few cases have been reported in English literature. We present the case of a young man who complained of pain on the posterolateral corner of the knee after a motor vehicle accident. Clinical examination and MRI findings revealed a complete rupture at the musculotendinous junction of distal biceps femoris tendon. We describe the surgical treatment performed, and the clinical outcome.

Complete disruption of vastus intermedius tendon and partial rupture of vastus medialis tendon.

Quadriceps tendon ruptures are common injuries, however isolated ruptures are rare. Particularly, reports for isolated vastus intermedius ruptures are very scarce. We present a case of a 62-years-old male patient who sustained a complete rupture of vastus intermedius tendon with a partial rupture of vastus medialis while rectus femoris tendon was intact, after a fall from standing height. Due to lag in extension, surgical treatment was performed, consisted of an end-to-end Krakow suture technique accompanied with two anchors placed on osseous attachment to the superior pole of the patella. A hinged knee brace locked in full extension was applied for 4 weeks. Gradual range of flexion was suggested after the 3rd postoperative week. Full range of motion was achieved in the 7th postoperative week.

Biophysical Enhancement in Fracture Healing: A Review of the Literature.

Bone healing constitutes a complex process involving cellular and pathophysiological mechanisms. Despite progress in osteosynthesis techniques, fracture union continues to be challenging. In some cases, it is not ultimately achieved or is delayed relative to the expected time resulting in economic and social outcomes for the patient and the health system. In addition to surgical treatment, biophysical methods have been developed to assist in fracture healing used in combination or individually. Biophysical stimulation is a non-invasive therapy used in orthopedic practice to increase and enhance tissue's reparative and anabolic activities. This study reviewed the existing literature, including electromagnetic fields, ultrasound, laser, extracorporeal shockwave therapy, and electrical stimulation, and revealed the efficacy of biophysical stimulation for bone healing. This study aims to define if these methods are helpful, especially in cases of non-union. Biophysical stimulation requires care and precision in use to ensure the success expected of it by physicians and patients.

Acetabular erosion after bipolar hip hemiarthroplasty for femoral neck fracture in elderly patients: a retrospective study.

BACKGROUND: The choice between total hip arthroplasty (THA) and hemiarthroplasty (HA) to treat displaced femoral neck fractures, particularly among the elderly, is still controversial. Acetabular erosion consists of a late multifactorial process that may happen after hip HA resulting in significant postoperative burden. This study aims to investigate the impact of acetabular erosion progress after hip HA in patients over 70 years old. MATERIALS AND METHODS: This is a 5-year (2013-2018) retrospective study including consecutive series of patients >70 years who were treated with bipolar hip HA for femoral neck fractures. Patients were categorised into 3 groups for analysis (A = 70-75 years, B = 75-80 years, C = >80 years). The study enrolled a total number of 813 patients who met the inclusion criteria. We assessed acetabular erosion through radiological examinations and measured functional deterioration using the modified Harris Hip Score (mHHS) at 6 and 12 months follow-up. Our comprehensive investigation extended over a maximum period of 5 years. The correlation of patients' characteristics and HA features on erosion progress was assessed. RESULTS: There were no significant differences in sex distribution, injury side, BMI, ASA score, bipolar head diameter, mHHS and leg-length discrepancy among the groups (p > 0.05). During the follow-up period, acetabular erosion with consequential conversion to THA was observed in 6.13%, 4.22% and 1.96% for Groups A, B and C respectively (p = 0.009). A statistically significant difference of acetabular erosion was observed in Group A compared to patients of Group C. CONCLUSIONS: Age constitutes a significant factor of acetabular wear after HA in the elderly. The higher rate of acetabular wear in patients <75 years suggests that THA is a more viable option, as HA is for patients >80 years old.

Cryptococcus neoformans osteomyelitis of the tibia: a case report and review of the literature.

INTRODUCTION: Osteomyelitis is a bone inflammation that can be related to various infectious agents. As with any other type of inflammation, the prevailing symptoms and signs may include redness, swelling, pain, and heat. Fungal osteomyelitis is rare and usually found in immune-compromised patients. CASE PRESENTATION: A non-human immunodeficiency virus immunocompromised Greek female patient, 82 years old, visited the emergency department due to a 3 day pain located mainly over the left tibia's anterior surface, accompanied by swelling and redness. There was also a subcutaneous lesion of her left breast. Medical history revealed that the patient had an unmasked close contact with pigeons, a main host of the disease. Initial x-ray imaging showed an osteolytic area in the upper third of the tibial diaphysis. The patient was admitted and underwent a computed tomography-guided biopsy. The specimen revealed a Cryptococcus neoformans infection of the bone and the breast. She was treated with 400 mg fluconazole twice a day for 3 weeks while in hospital and 200 mg twice a day upon discharge for 9 months. After that, she underwent surgical debridement because of lasting local irritation. She was closely monitored in our outpatient office, and in her last visit, 1 year after the initial admission, inflammatory signs had regressed vastly. CONCLUSIONS: To our knowledge, this is the ninth cryptococcal osteomyelitis of the tibia to be recorded since 1974, and the most unusual finding was the bifocal nature of the infection, affecting both the tibia and the breast.

Angiogenesis in Spinal Cord Injury: Progress and Treatment.

Traumatic spinal cord injury (SCI) provokes the onset of an intricate pathological process. Initial primary injury ruptures local micro-neuro-vascularcomplex triggering the commencement of multi-factorial secondary sequences which exert significant influence on neurological deterioration progress. Stimulating by local ischemia, neovascularization pathways emerge to provide neuroprotection and improve functional recovery. Although angiogenetic processes are prompted, newly formed vascular system is frequently inadequate to distribute sufficient blood supply and improve axonal recovery. Several treatment interventions have been endeavored to achieve the optimal conditions in SCI microenvironment, enhancing angiogenesis and improve functional recovery. In this study we review the revascularization pathogenesis and importance within the secondary processes and condense the proangiogenic influence of several angiogenetic-targeted treatment interventions.

New Strategies in Neurogenic Heterotopic Ossification.

The term neurogenic heterotopic ossification (NHO) is used to describe the pathological bone formation in soft tissues, due to spinal cord or brain injury. Commonly is presented with pain and stiffness of the affected joint. NHO affects the quality of life of these patients, delays their rehabilitation and therefore increases morbidity. The aim of this article is to emphasize pathophysiology mechanism and review new molecular treatments of heterotopic ossification (HO). It was demonstrated that potent treatment strategies are based on understanding the molecular mechanisms and aiming to inhibit the pathological process of the HO in various stages. New treatments are targeting several factors such as bone morphogenetic proteins (BMPs), retinoic acid receptors (RARs), hypoxic inhibitors (Hif1-inhibitors, rapamycin), free radical scavengers and immunological agents (imatinib). The endogenous pathways that lead to HO at molecular and cellular levels have been the aim of many studies in recent years. New treatment options for HO should be recommended due to the ineffectiveness of traditional older options, such as anti-inflammatory drugs and radiation, especially in the case of NHO.

Treatment of Schatzker Type II-VI Tibial Plateau Fractures by Means of Syndesmotaxis Using an Ilizarov External Fixator and Postoperative CT Evaluation.

Introduction Tibial plateau fractures are more common in young patients following high-energy trauma. In this study, we aim to evaluate the articular surface reduction quality by means of postoperative computer tomography (CT) in Schatzker type II-VI tibial plateau fractures treated with an Ilizarov frame. Materials and methods This case series study included 45 patients with a mean age of 39.5 years (range: 18 to 65 years) with a Schatzker type II-VI tibial plateau fracture. The surgical technique was a mini-open reduction of the articular surface impaction followed by application of an Ilizarov circular frame with knee bridging. Pre- and postoperative CT scan evaluation was performed in all of the patients. Outcomes were measured using the American Knee Society Score (AKSS). Mean outpatient follow-up was of at least 12 months (range: 12 to 21 months). Mean time for fracture consolidation was 15.5 weeks (range: 13 to 19 weeks). According to the degree of postoperative articular surface impaction, patients were grouped as follows: 11 had less than 2 mm of depression, 27 had 2 to 4 mm of depression, and 7 over 4 mm of depression. Results Patients with articular surface impaction of more than 4 mm presented statistically significant lower values of AKSS compared to those with impaction of lower than 2 mm (p<0.001 ) and 2-4 mm (p<0.001). Patients with joint alignment equal to or more than 5° presented statistically significant lower values of AKSS compared to those with lower than 5°. Conclusions Schatzker type II-VI tibial plateau fractures may be treated successfully with mini-open reduction and the application of an Ilizarov frame. The increase of articular surface impaction by 1 mm causes reduction of AKSS by 15 units. Patients with joint alignment equal to or more than 5° present lower values of AKSS. The preoperative CT scan is important and useful in planning the surgical intervention no matter the classification system is used.

Drill-guided femoral nail extraction: a novel technique.

Femoral nail extraction, although it is considered a challenging procedure for orthopedic surgeons, can be simplified. We present a new technique to aid the removal of a proximally (antegrade) inserted femoral nail by applying drilling consecutively in order to identify the margins and depth of the nail into the intramedyllary canal of the femur. The damage to the bone is minimal as we use k-wires or drilling and in our practice was uneventful. This technique is the first to be reported in literature. Most authors suggest techniques that enable radiolucent table and fluoroscopy techniques using C-arm. With this technique, traction table and fluoroscopy techniques seem to be less essential to accomplish the removal of a proximally (antegrade) inserted femoral nail.

Peroneus brevis tendon injuries: Report of two cases and review of literature.

The incidence of peroneal tendon disorders in the population is unknown and they are usually overlooked. We report two cases of peroneus brevis injuries and a comprehensive literature review was performed. The first case was a 53-year-old man presented with persistent pain on the lateral aspect on the left ankle during the last four years and difficulty to bear weight during the last year. MRI showed longitudinal tear of peroneus brevis tendon and the patient underwent surgical treatment. The second case was a 46-year-old woman with persistent pain on the lateral aspect of the ankle with a history of a road traffic accident two years ago. Although MRI showed a peroneus brevis tendon tear, this was a false positive finding. Surgical treatment revealed no tear and symphysiolysis managed to relieve patient's symptoms. Even though MRI is the most effective diagnostic tool in depicting peroneal tendon injuries, there are false positive findings. In cases when symptoms persist, surgical exploration is indicated.

Falls from height due to accident and suicide attempt in Greece. A comparison of the injury patterns.

BACKGROUND: Falls from height are a common cause of death and disability. Falls from height can be divided between accidental and suicide attempts. The aim of this study is to ascertain the demographic characteristics of these patients, and to identify the fracture patterns. METHODS: In this retrospective cross sectional comparative study we present 244 patients who sustained injuries as a result of a fall from height. They were divided into those with accidental falls (n = 180, group I) and those with suicide attempts (n = 64, group II). Data collected included age, gender, associated trauma, injury severity score (ISS), Glasgow Coma Scale (GCS), haemodynamic status, length of intensive care unit (ICU) and hospital stay. The diagnosis of mental disorder was ascertained by psychiatric specialists using the criteria of the International Classification of Disease Ninth Version Clinical Modification (ICD - 9CM). Postoperative follow-up ranged from 12 months to 10 years. RESULTS: The injuries sustained were as follows: Abdominal trauma in 9 cases (5 in group I, 4 in II), thoracic trauma in 81 cases (49 in group I, 32 in II), head injury in 23 cases (7 in group I, 16 in II), 383 extremities fractures (184 in group I, 199 in II) and 133 spinal fractures (101 in group I, 32 in II). Twenty-one patients died in hospital while 223 patients survived to hospital discharge. The mean height from which the fall occurred was 5.4 m (range, 3 - 25 m). The mean Injury Severity Score was 19 (range, 6 to 58) for all fall victims. CONCLUSIONS: Patients following an accidental high fall mostly had upper limb fractures. Patients following a suicidal high fall mostly had lower limb fractures, pelvis, spinal fractures and head injuries. Spinal fractures are common either when the fall is accidental or following suicide attempt.
