RESUMEN
Renal cell carcinoma accounts for 2-3% of all malignant neoplasms. Metastatic disease of the spine is common and 50% of bone metastases are already present at the time of primary diagnosis. Bone metastases from renal cell carcinoma are difficult to manage, especially vertebral localization.A 48-year-old woman was diagnosed with renal cell carcinoma in the context of low back pain. The patient presented two skeleton metastases at diagnosis (T11 and 5th rib). The patient received neoadjuvant treatment with cabozantinib, followed by removal of the renal tumor. Radiotherapy was administered for the lumbar lesion. In spite of the radiotherapy treatment, increased low back pain limiting mobility and ambulation. MRI showed an occupation of the spinal canal, without neurological lesion. The SINS scale revealed a score of 14 (vertebral instability). The patient's prognosis was greater than 12 months according to the Tokuhashi score. Based on clinical and mechanical criteria, surgical treatment of the vertebral lesion was decided. T11 vertebrectomy was performed, the reconstruction was made with an expandable cage, and T8 a L2 posterior spinal arthrodesis. A partial resection of the fifth rib was performed in order to remove the whole macroscopic tumor. After 3 months, she was diagnosed with a local infection, treated by irrigation, debridement and antibiotherapy, with good evolution. At 1-year follow-up, she has no low back pain or functional limitation. Follow-up chest-abdomen-pelvis computed CT scan showed absence of disease progression, furthermore, the vertebral arthrodesis shows fusion signs. At the time of this report, there are no clinical or radiological data of infection
El carcinoma de células renales representa el 2-3% de todas las neoplasias malignas. La enfermedad metastásica de la columna vertebral es frecuente y el 50% de las metástasis óseas ya están presentes en el momento del diagnóstico. Las metástasis óseas del carcinoma de células renales son difíciles de manejar, especialmente en localización vertebral.Una mujer de 48 años fue diagnosticada de carcinoma de células renales en el contexto de un dolor lumbar. La paciente presentaba dos metástasis óseas en el momento del diagnóstico (T11 y 5ª costilla). Inicialmente recibió tratamiento neoadyuvante con cabozantinib, seguido de la extirpación quirúrgica del tumor renal. Se administró radioterapia para la lesión lumbar. A pesar del tratamiento radioterápico, aumentó el dolor lumbar con limitación para la movilidad y la deambulación. La RM mostró una ocupación del canal espinal, sin lesión neurológica. La escala SINS reveló una puntuación de 14 (inestabilidad vertebral). El pronóstico de la paciente era superior a 12 meses según la puntuación de Tokuhashi. Basándose en criterios clínicos y mecánicos, se decidió el tratamiento quirúrgico de la lesión vertebral. Se realizó una vertebrectomía de T11, para la reconstrucción se usó una caja extensible, junto con una artrodesis vertebral T8-L2. Se realizó una resección parcial de la quinta costilla para eliminar todo el tumor macroscópico. A los 3 meses de la cirugía la paciente fue diagnosticada de infección local, tratada mediante irrigación, desbridamiento y antibioterapia, con buena evolución. Al año de seguimiento, no presenta dolor lumbar ni limitación funcional. La tomografía computarizada de tórax-abdomen-pelvis de seguimiento mostró ausencia de progresión de la enfermedad, además, la artrodesis vertebral muestra signos de fusión. En el momento de este informe, no hay datos clínicos ni radiológicos de infección.

INTRODUCTION: To analyze the effect of the COVID-19 pandemic on the provision of fragility hip fracture care, comparing patients treated before cohorting and in separate COVID-19 and non-COVID-19 circuits with the corresponding months in 2018 and 2019. MATERIALS AND METHODS: Retrospective single-center cohort study including 64 patients with fragility hip fractures treated during the COVID-19 pandemic (March 1st-May 1st, 2020), compared to 172 patients treated in 2018 and 2019. Dedicated COVID-19 and non-COVID-19 circuits were established on March 14th. Patients treated before cohorting (17 patients), in COVID-19 (14 patients) and non-COVID-19 circuits (33 patients) were included. RESULTS: Baseline characteristics were similar for 2018-19 and 2020. Patients in 2020 had a lower median surgical delay (50.5 vs. 91.3 h) and length of stay (9.0 vs. 14.0 days), while those with COVID-19, had longer surgical delays and length of stay (87.7 h and 15.0 days, respectively). Thirty-days mortality was higher among patients before cohorting, but similar in Covid-19 and non-Covid-19 pathways compared to 2018-19 (7.1% and 3.0% vs 5.2%, respectively). 23.5% of patients treated before circuiting suffered coronavirus infectious disease-19 disease after discharge. Following separation, no secondary cases of coronavirus infectious disease-19 were observed. CONCLUSIONS: Separate circuits for patients with and without coronavirus infectious disease-19 provided adequate hip fracture care. We did not observe increased mortality rates among hip fracture patients with preoperatively confirmed or suspected coronavirus infectious disease-19, compared to negative cases and 2018-19. Delaying surgery among patients with severe respiratory illness until a favourable trend could be observed did not lead to increased mortality.

INTRODUCTION: The aim was to study the incidence and characteristics of fragility hip fractures admitted during COVID-19 lockdown. MATERIALS AND METHODS: We analysed socio-demographic and baseline characteristics of patients suffering fragility hip fractures between March 1st and May 1st 2020, period most affected by COVID-19 confinement measures. Cases (n = 64) were compared with controls (n = 172) from corresponding periods in 2018 and 2019. Poisson Generalised Linear Model regression analysis was performed to compare daily case counts, and LOESS curves compared time series. RESULTS: No differences were found regarding age or gender distributions, pre-fracture living, ambulatory, functional or cognitive status. More patients in 2020 had a high-risk ASA score. Fewer cases [Reduction = 26% (95% CI 1-44%)] were admitted in 2020. The reduction seemed to correspond with confinement. CONCLUSIONS: Approximately, one quarter less fragility hip fractures were admitted to our hospital during lockdown. Patients' baseline status and socio-demographic characteristics were similar.

INTRODUCTION: The purpose of this study is to analyze the mid-term outcomes of a modular monopolar type of radial head arthroplasty in the treatment of complex fractures associated with acute elbow joint instability. We postulated that radiographic changes are related to the development of clinical complications. MATERIALS AND METHODS: We evaluated at last follow-up 26 radial head arthroplasties in 26 consecutive patients who were followed for at least one and a half year. All patients had suffered radial head fractures (Mason III) in the context of unstable elbow injuries. Definitive treatment of the radial fracture was performed with modular and monopolar prosthesis which was inserted as a press fit. All patients were evaluated preoperatively and postoperatively. The evaluation included a clinical examination and a protocolized imaging study (standard X-Rays and CT) of the elbow. We analyzed the incidence of: heterotopic ossifications, secondary radiocapitellar joint osteoarthritis, hardware loosening, hardware disengagement, and joint infection. Diagnosis of clinical failure of the implant was defined as the time to the second surgery due to major complications related to the prosthesis, such as persistent lateral side pain or elbow stiffness and any kind of implant instability or dislocation. RESULTS: The implant-specific reoperation rate was 15% (four reoperations). The need for the second surgery was statistically associated with heterotopic ossifications, radiocapitellar osteoarthritis and cortical resorption around radial neck (p = 0.054, p = 0.033, and p = 0.019, respectively), being periprosthetic osteolysis the most likely factor related to failure, and radial pain the main symptom leading to surgical revision. CONCLUSIONS: Our study shows a positive association between radiographic findings and patient symptoms for postoperative complications after radial head arthroplasty. Failed radial head replacements may lead to reoperation mainly due to pain, and this can be distinguished from other causes of pain in elbow region based on its radial location. Radiological loosening was prevalent in this group of failed replacement.

BACKGROUND: Subtalar arthrodesis is a treatment option for pain due to posttraumatic arthritis following calcaneal fractures. The goal of this study is to examine the results of arthroscopic subtalar arthrodesis for posttraumatic arthritis following calcaneal fractures. PATIENTS AND METHODS: We performed a retrospective case series reviewing 37 consecutive patients (36 male) treated for posttraumatic arthritis following calcaneal fractures by arthroscopic subtalar arthrodesis. The fractures were due to high-energy injuries in 81% of cases, and 12 fractures (32.4%) had been previously treated with internal fixation. Average follow-up was 57.5 months. RESULTS: Average American Orthopedic Foot and Ankle Society (AOFAS) scores significantly improved from 49.0 ± 10.9 points preoperatively to 76.0 ± 8.0 points at final follow-up. Average time to union was 12.5 weeks. Six patients (16.2%) suffered complications: superficial wound infection (2.7%), symptomatic hardware that warranted removal (5.4%) and nonunion (8.1%) presented nonunion. All three cases had prior internal fixation through an extensile lateral approach, and fused after a repeat surgery. CONCLUSION: Arthroscopic subtalar arthrodesis offers consistent improvement in cases of posttraumatic arthritis following calcaneal fractures, with a union rate similar to published series of open arthrodesis. We observed more nonunions in patients who had been treated previously with internal fixation. In spite of this, we continue to recommend arthroscopic subtalar arthrodesis, as it preserves the soft tissue envelope better than open techniques.

A chondroblastoma-like osteosarcoma (CLO) in the proximal epiphysis and metaphysis of the tibia in a 30-year-old male is presented. With a wrong diagnosis of chondroblastoma, an aggressive curettage was performed. Later, the patient refused en-bloc resection. Seven years after surgery, there has been no local recurrence, and the patient is living an ordinary and active life. CLO is a very uncommon and controversial histologic subtype of osteosarcoma that can be misdiagnosed as chondroblastoma and therefore incorrectly treated. However, aggressive curettage with its functional advantages could be a reasonable option in selected cases.

INTRODUCTION AND OBJECTIVE: The systematic analysis of a carpal transverse ligament (CTL) sample obtained during routine carpal tunnel syndrome (CTS) surgery may constitute a method of early diagnosis for systemic amyloidosis. MATERIAL AND METHODS: Prospective study carried out on 147 consecutive CTL samples collected from patients intervened for CTS at the University Hospital of León from April 2006 to May 2007. In those cases in which amyloid deposition was observed in the CTL sample, the study was completed with a fine needle aspiration biopsy (FNAB) of the subcutaneous fascia, using the Red Congo stain in both cases. Positive cases were referred to the Internal Medicine and/or Hematology departments, and their evolution was monitored for up to 8 years. RESULTS: CTL amyloid deposition was observed in 29 patients (19.7%), with a FNAB only being performed in 19 of them (65.5%). The test was positive in 11 cases (57.9%), and 4 patients in this subgroup (3% of the total) developed events attributable to amyloidosis over the following 3 years. CONCLUSIONS: A CTL routine biopsy carried out during CTS surgery may anticipate the systemic amyloidosis diagnosis.
