Objetivo: Comparar a mediano y largo plazo los resultados quirúrgicos postoperatorios, sobre todo la tasa del síndrome adyacente, tasa de eventos adversos y tasa de reoperación, de los pacientes operados con artroplastia cervical o artrodesis cervical anterior en los ensayos clínicos aleatorizados (ECA) publicados de un nivel cervical. Métodos: Revisión sistemática y metaanálisis. Se seleccionaron 13 ECA. Se analizaron los resultados clínicos, radiológicos y quirúrgicos, tomando como variables primarias la tasa del síndrome adyacente, tasa de eventos adversos y tasa de reoperación. Resultados: Fueron 2.963 los pacientes analizados. El grupo de artroplastia cervical mostró una menor tasa de síndrome adyacente superior (p<0,001), menor tasa de reoperación (p<0,001), menor dolor radicular (p=0,002) y una mejor puntuación en el índice de discapacidad cervical (p=0,02) y en el componente físico SF-36 (p=0,01). No se encontraron diferencias significativas en la tasa del síndrome adyacente inferior, tasa de eventos adversos, dolor cervical ni componente mental SF-36. Se halló en la artroplastia cervical un rango de movilidad medio de 7,91 grados en el seguimiento final y una tasa de osificación heterotópica de 9,67%. Conclusión: En el seguimiento a mediano y largo plazo, la artroplastia cervical mostró menor tasa de síndrome adyacente superior y menor tasa de reintervención. No se hallaron diferencias estadísticamente significativas en la tasa del síndrome adyacente inferior ni en la tasa de eventos adversos.(AU)

Objective: To compare medium- and long-term postoperative surgical results, especially the adjacent syndrome rate, adverse event rate, and reoperation rate, of patients operated on with cervical arthroplasty or anterior cervical arthrodesis in published randomized clinical trials (RCTs), at one cervical level. Methods: Systematic review and meta-analysis. Thirteen RCTs were selected. The clinical, radiological and surgical results were analyzed, taking the adjacent syndrome rate and the reoperation rate as the primary objective of the study.

[Translated article] Risk of venous thromboembolism in thromboprophylaxis between aspirin and low molecular weight heparins after total hip arthroplasty or total knee arthroplasty: Systematic review and meta-analysis.

INTRODUCTION: The aim of this study was to evaluate the efficacy of aspirin versus low molecular weight heparins (LMWH) for the prophylaxis of venous thromboembolism (VTE), deep vein thrombosis (DVT) and pulmonary embolism (PE) in patients undergoing total knee arthroplasty (TKA) and/or total hip arthroplasty (THA). MATERIALS AND METHODS: Systematic review and meta-analysis. Sixteen studies were selected. The risk of VTE, DVT and PE were analysed. Mortality, risk of bleeding and surgical wound complications was also analysed. RESULTS: 248,461 patients were included. 176,406 patients with thromboprophylaxis with LMWH and 72,055 patients with aspirin thromboprophylaxis. There were no significant differences in the risk of VTE (OR=0.93; 95% CI: 0.69-1.26; p=0.64), DVT (OR=0.72; 95% CI: 0.43-1.20; p=0.21) or PE (OR=1.13; 95% CI: 0.86-1.49; p=0.38) between both groups. No significant differences were found in mortality (p=0.30), bleeding (p=0.22), or complications in the surgical wound (p=0.85) between both groups. These same findings were found in the sub-analysis of only randomised clinical trials (p>0.05). CONCLUSIONS: No increased risk of PE, DVT, or VTE was found among patients with aspirin thromboprophylaxis versus patients with LMWH thromboprophylaxis. There was also no greater mortality, greater bleeding, or greater complications in the surgical wound found among patients with aspirin thromboprophylaxis versus patients with LMWH thromboprophylaxis.

Arthroscopic rotator cuff repair using a single or double row technique: A meta-analysis of randomized clinical trial. / Reparación artroscópica del manguito rotador mediante una técnica de hilera simple o doble hilera: un metaanálisis de los ensayos clínicos aleatorizados.

PURPOSE: To compare the double row technique versus the single row technique for arthroscopic rotator cuff repair, in order to assess whether there are clinical differences. METHODS: Systematic review of randomized clinical trials comparing the clinical results of the double-row technique versus the single-row technique in arthroscopic rotator cuff repair. Demographic, clinical, and surgical variables were analyzed, including functional scores, tendon healing rate, and re-tear rate. RESULTS: Thirteen randomized clinical trials were selected. 437 patients in the single row group (50.7%) and 424 patients in the double row group (49.3%) were analyzed. No significant differences were found between the two groups in terms of age (P=.84), sex (P=.23) and loss to follow-up (P=.52). Significant differences were found for the better results of the double row technique at the UCLA level (P=.01). No significant differences were found on the Constant-Murley scale (P=.87) or on the ASES scale (P=.56). Similarly, there was a higher healing rate (P=.006) and less risk of rotator cuff re-tears with the double row technique (P=.006). CONCLUSIONS: In rotator cuff repair, the double row technique was found to be superior to the single row technique in terms of better UCLA score, better tendon healing rate, and lower re-tear rate. No clinically significant differences were found on the Constant-Murley scale or on the ASES scale.

Total hip arthroplasty associated with transverse subtrochanteric shortening osteotomy and conical stem fixation in Crowe type IV hip dysplasia.

PURPOSE: Total hip arthroplasty (THA) in high-dislocated hip dysplasia is a surgical challenge, presenting difficulties in the biomechanical reconstruction of the hip. The purpose of the present study is to analyze clinical and radiological outcomes of a series of patients with Crowe type IV hip dysplasia who underwent a THA with transverse subtrochanteric shortening osteotomy and conical stem fixation in our Hip surgery unit. METHODS: This non-interventional retrospective study included all patients diagnosed with Crowe type IV hip dysplasia who underwent a THA using a subtrochanteric shortening osteotomy and uncemented conical stem fixation between January 1, 2008, and December 31, 2015. Demographic, clinical and radiologic data were analyzed, including Harris Hip Score and Oxford Hip Score. RESULTS: Seventeen hips in 13 patients were included in the final analysis. All patients were women and mean age was 39 years (range 35-45). Mean follow-up was 5.6 years (range 1-8). Average length of the osteotomy was 3.4 cm (range 3-4.5) and mean lowering of the center of rotation was 5.67 cm (range 3.8-9.1). Mean time for bone union was 5.5 months. No nerve palsy or non-union was detected at the end of follow-up period. CONCLUSION: The use of cementless conical stem fixation associated with a transverse subtrochanteric shortening osteotomy for treating Crowe type IV hip dysplasia permits to correct the rotational alterations of the femur and provides good stability of the osteotomy, with very low risk of nerve palsy and non-union rates.

Outcomes of posterior cruciate ligament tibial avulsion treated with staple fixation: stress TELOS X-ray evaluation.

PURPOSE: Tibial-side avulsion injuries of the posterior cruciate ligament are rare injuries. In displaced fracture, the reduction and fixation is the treatment of choice, although the optimal surgical management has not yet been determined. The aim of this study was to evaluate the clinical, functional, and radiological outcome after an open reduction and internal fixation with staples of a posterior cruciate ligament tibial avulsion. METHODS: A historical cohort of patients who underwent open reduction and internal fixation with staple due to a posterior cruciate ligament tibial avulsion were reviewed. Minimum follow-up was 2 years. Demographic, clinical, and radiological data, including stress X-ray, were analyzed. Also, International Knee Documentation Committee Score, Tegner Knee Score, Lysholm Knee Score, Short-Form Health Survey, and four-point Likert scale were evaluated. RESULTS: Four males (57%) and 3 females (43%) were included in the final analysis. The mean age was 39 years (range 27-54). All patients had a fracture union. No implant migration was observed. Postoperative posterior drawer, reverse pivot shift, and varus/valgus stress were negative. In stress TELOS X-ray, no statistically significant differences were observed between the postoperative and contralateral knee. All evaluated scores had good or excellent results. CONCLUSIONS: Our study provides further evidence that the use of an open reduction and internal fixation with a staple could be a simple and reliable management for posterior cruciate ligament avulsion fractures of the tibia. In our study, the postoperative stress TELOS X-ray analyze showed a correct fixation and biomechanical function of the posterior cruciate ligament.

Early dislocation in primary total hip arthroplasty using a posterior approach with repair of capsule and external rotators. / Luxación temprana en artroplastias total de cadera primarias realizadas mediante vía posterior con reparación capsular y de rotadores externos.

OBJECTIVE: To determine the incidence of dislocation after primary total hip arthroplasty using a posterior approach with repair of capsule and transosseous external rotators. MATERIAL AND METHOD: Historical cohort study between January 2009 and December 2015 of all the cases of dislocation of primary total hip arthroplasty operated using a posterior approach with repair of capsule and transosseous external rotators. Demographic and clinical data concerning the patient, surgery and dislocation were collected and analyzed. A descriptive analysis and a study of survival and risk function were performed by Kaplan Meier's method considering the appearance of a hip dislocation as the final event. RESULTS: The incidence of dislocation in our study was 1.2% (23 patients). In our study, the highest probability of dislocation occurred in the first 120 days. Forty-three point 5percent of the dislocated patients needed revision surgery. CONCLUSIONS: Capsular repair and transosseous reattachment of the external rotators can help to reduce the incidence of dislocation in patients undergoing primary total hip arthroplasty through a posterior approach.

Bilateral insufficiency hip fractures after bariatric surgery.

Bariatric surgery is one of the most common surgeries within developed countries due to the increase in morbid obesity that has been observed in the past decades. The short-term alterations in the metabolism of calcium and vitamin D are well known after these procedures; however, the clinical and biochemical consequences may not be detected for years or even remain undiagnosed. We present the first case of bilateral insufficiency hip fracture after years of bariatric surgery. Although this is a long-term and rare complication, with the high number of gastric bypass performed in the past years, the number of these cases could increase with time. Moreover, it is important as an undiagnosed hip fracture can cause a displacement that could need an arthroplasty, with all the complications that entails. For that reason, this long-term complication highlights the need to reevaluate the optimal follow-up of these patients and the importance to continue monitoring metabolic bone diseases in the prevention of insufficiency fractures.

Simultaneous bilateral atypical femoral fracture in a patient receiving denosumab: case report and literature review.

Osteoporosis remains a chronic and common disease associated with high medical costs. Pharmacological therapy has shown to be a good strategy to significantly reduce fracture risk. While literary evidence for bone protection in the short and medium term is strongly in it's favor, there are concerns about long-term treatment with antiresorptive drugs. Increased risk of atypical femoral fractures (AFFs) have been demonstrated in several studies following the long-term use of bisphosphonate. Denosumab offers an alternative approach to the treatment of osteoporosis, however, it is also an antiresorptive drug. We present a case of simultaneous bilateral atypical femoral fractures in a patient with denosumab treatment. These findings highlight the need to reevaluate the optimal antiresorptive therapy duration, as well as the safety of transition from bisphosphonates to denosumab and the need for continued monitoring in the prevention of AFFs.
