Long-term results of the AptisTM total distal radioulnar joint prosthesis after previous failed surgical procedures.

We present a prospective study with the results of ten Aptis total distal radioulnar joint replacements in patients who had one to five previous operations. The mean postoperative follow-up was 9.7 years (range 3-14.7). The mean postoperative range of motion of the wrist improved by 9° for extension, 15° for flexion, 10° for pronation and 14° for supination, achieving values equivalent to 88%, 78%, 97% and 88% of those of the non-operated hand. There were minimal changes in radial and ulnar deviations. Grip strength improved by 7 kg, pain decreased by 8 points, QuickDASH and Mayo wrist scores improved by 51 and 53 points, respectively. Two implants had radiolucency less than 1 mm. Serum titanium ion levels were slightly elevated in two patients. Three prostheses required revision surgery for heterotopic ossification, a prominent radial screw and a periprosthetic fracture. No prostheses were removed. Six patients returned to their former professional activities and four patients adapted their jobs.Level of evidence: IV.

Total wrist fusion versus total wrist prosthesis: a comparative study.

We present a comparative study of 41 total wrist fusions (TWFs) with contoured plate and 22 total wrist prostheses using the Universal 2™ model, with a mean follow-up of 6 years for the fusion and 6.5 years for the prosthesis. We evaluated grip strength, pain according to the visual analogue scale, functional results using the Quick Disabilities of the Arm, Shoulder and Hand and the Patient-Rated Wrist Evaluation, degree of satisfaction and complications, with no significant differences being observed in any of these variables. The results allow us to conclude that total wrist prosthesis implanted in patients with low or moderate functional demands offers medium-term functional results similar to TWF without increasing the number of complications.Level of evidence: III.

Postoperative assessment and management of metallosis and periprosthetic osteolysis in patients treated with metal-on-polyethylene total wrist prostheses.

We analysed the relationship between serum metal ions, radiological periprosthetic osteolysis and the clinical features in a series of 25 patients treated with fourth-generation metal-on-polyethylene total wrist prostheses. The mean implant follow-up was 7 years. Our results show that titanium was the main elevated serum metal ion in patients with the prostheses that we used; elevated serum cobalt or chromium values were infrequent. The risk of loosening was higher in an implant older than 6 years, with more than five periprosthetic osteolysis points according to our radiograph zone system, and serum titanium values between 26 to 31 µg/L. The presence of metallosis pseudotumours does not guarantee but increases the risk of implant failure, which may be asymptomatic or associated with little pain.Level of evidence: IV.

[Hip fracture due to osteomalacia secondary to celiac disease] / Fractura de cadera debida a osteomalacia secundaria a enfermedad celíaca

Background: Hip fracture in the young patient is uncommon, but it can have devastating consequences. This pathology in the context of minimal trauma obliges us to carry out a study on calcium metabolism to determine the primary cause. Material and methods: We present a clinical case about an 18-year-old male patient who suffered a subcapital fracture of the left hip due to minimal trauma while playing football. The patient was treated urgently by means of closed reduction and internal fixation with two spongy screws. Subsequently, the metabolism study showed a severe vitamin D deficiency (27.1 nmol/L - normal above 75 nmol/L) and high levels of anti-transglutaminase IgA antibodies (2502.40 U/mL). The digestive biopsy confirmed the diagnosis of celiac disease and was treated with a gluten-free diet and calcium and vitamin D supplements. Results: After two years of follow-up, the patient is pain free, with complete hip mobility. There have been no complications (failure of osteosynthesis, avascular necrosis or pseudoarthrosis) and serum levels of vitamin D as well as IgA antibodies against transglutaminase have normalized. Conclusion: In young patients with low energy trauma fractures, vitamin D deficiency must be considered as a possible etiology and the reason for such osteomalacia, such as celiac disease, must be identified.

Antecedentes: La fractura de cadera en el paciente joven es infrecuente, pero puede tener unas consecuencias devastadoras. Esta patología en el contexto de un traumatismo mínimo nos obliga a realizar un estudio sobre el metabolismo del calcio para filiar la causa primaria. Material y método: Presentamos un caso clínico sobre un paciente varón de 18 años que sufrió una fractura subcapital de cadera izquierda debido a un traumatismo mínimo mientras jugaba al fútbol. El paciente fue tratado quirúrgicamente de urgencia mediante reducción cerrada y fijación interna con dos tornillos de esponjosa. Posteriormente, el estudio del metabolismo mostró una deficiencia grave de vitamina D (27.1 nmol/L ­ normal por encima de 75 nmol/L) y altos niveles de anticuerpos IgA antitransglutaminasa (2502.40 U/mL). La biopsia digestiva confirmó el diagnóstico de enfermedad celíaca por lo que fue tratado con una dieta libre de gluten y suplementos de calcio y vitamina D. Resultados: Tras dos años de seguimiento, el paciente está libre de dolor, con movilidad completa de la cadera. No ha habido complicaciones (fracaso de la osteosíntesis, necrosis avascular o pseudoartrosis) y los niveles séricos de vitamina D así como de los anticuerpos IgA antitransglutaminasa se han normalizado. Conclusión: En pacientes jóvenes que presentan fracturas por traumatismos de baja energía, se ha de tener en cuenta la deficiencia de vitamina D como posible etiología y se debe identificar el motivo de dicha osteomalacia, como es la enfermedad celíaca. Conclusión: En pacientes jóvenes que presentan fracturas por traumatismos de baja energía, se ha de tener en cuenta la deficiencia de vitamina D como posible etiología y se debe identificar el motivo de dicha osteomalacia, como es la enfermedad celíaca.

Results of the total wrist arthrodesis with contoured plate in a series of 41 wrists with median follow-up of 6 years.

We present a comparative analysis between the pre and postoperative status of 41 wrists subjected to total arthrodesis with contoured plate, analysing the functional and radiological results, subjective satisfaction and return to work. The indications for surgery were post-traumatic arthritis (56.1%), Kien- böck's disease (17.1%), rheumatic disease (14.6%) or other reasons (12.2%). In 75.6% of the procedures, proximal row carpectomy took place prior to or at the same time as the surgical fusion procedure. The median follow-up was 6 years. Postoperatively, pain decreased by 7.5 points on the Visual Analogue Scale and grip strength increased by 6.3 kg. The improvement in the Quick Disabilities of the Arm, Shoulder and Hand was 43.5 points and 53.2 in the Patient- Rated Wrist Evaluation. All changes were statistically significant. There were postoperative complications in 14.6% of the arthrodesis procedures. Radiocarpal fusion was complete in 97.6% of cases. Finally, 62.5% of patients were able to return to work, with 92.5% being satisfied or very satisfied. These results allow us to conclude that, in the medium term, total wrist arthrodesis with contoured plate is a reliable and safe technique for the treatment of advanced radiocarpal arthritis.

Acute rupture of distal biceps: Repair using a single anterior approach and cortical anchoring device / [Rotura aguda de bíceps distal: reparación mediante abordaje único anterior y dispositivo de anclaje cortical]

Background: Rupture of the distal tendon of the biceps is a pathology with an increasing incidence, which can cause important functional alterations. When the rupture is complete and the patient is active, surgical treatment is of choice. Material and method: 47-year-old man with sudden and intense pain in the left antecubital fossa while lifting weight. On examination, impotence for flexion and active supination of the left arm with loss of the biceps silhouette. Ultrasonography confirms the diagnosis of complete rupture of the distal biceps tendon. Surgical treatment was decided, performing a single anterior approach and reinserting the tendon in its radial footprint with the help of a cortical anchorage device. Results: At 12 months, the patient presented flexo-extension and complete prone supination, without encountering difficulties in carrying out the activities of his daily and work life, with a score of 100 points in the Mayo Elbow Performance Score (MEPS). Conclusion: Rupture of the distal biceps is a typical injury in active patients with an increasing incidence. Although there have been no significant differences between the different repair options, in our experience the use of cortical anchorage devices with a single anterior approach provides very satisfactory results.

Se decide tratamiento quirúrgico, realizando un abordaje único anterior  y reinsertando el tendón en su "footprint" radial con ayuda de un dispositivo de anclaje cortical. Conclusión: La rotura del bíceps distal es una lesión típica de pacientes activos con una incidencia creciente. Aunque no se han evidenciado diferencias significativas entre las distintas opciones de reparación, en nuestra experiencia la utilización de dispositivos de anclaje cortical con un abordaje único anterior aporta unos resultados muy satisfactorios.

Surgical clavicle reconstruction after aneurysmal bone cyst resection in a child: A simple method.

The clavicle is an infrequent location for primary tumors in general, and aneurysmal bone cyst (ABC) of the clavicle is particularly rare. The challenge of the functional and esthetic result in the treatment of these lesions in the pediatric population is high when considering the reconstruction of critical bone defects. In this article, we present the case of a seven-year-old boy with an ABC in the middle third of the clavicle, treated by resection and reconstruction with free autograft of the fibula stabilized by using an intramedullary titanium nail. We offer a description of the used technique, considerations about treatment options in children, and a follow-up of more than two-and-a-half years.

Effective surgical solution to a complete rupture of the pectoralis major. / [Eficaz solución quirúrgica a una rotura completa del pectoral mayor.]

Background: The rupture of the pectoralis major muscle is rare, occurring typically in young male athletes. When the break is complete and the patient active, surgical treatment is the choice. Clinical case: 48-year-old man with severe pain in left shoulder after lifting weights. He presents impotence to adduction and internal rotation of the shoulder with thinning of the axillary fold. MRI confirms the diagnosis of complete rupture of the pectoralis major. Surgical treatment was decided, performing a deltopectoral approach and reinserting the pectoralis major tendon with three cortical buttons. Conclusion: The rupture of the pectoralis major is a typical lesion of active young patients with an increasing incidence. Although there have been no significant differences between the different repair options, in our experience the use of cortical buttons provides very satisfactory results.

A la exploración, impotencia a la aducción y rotación interna del hombro con adelgazamiento del pliegue axilar. La RMN confirma el diagnóstico de rotura completa del pectoral mayor. Se decide tratamiento quirúrgico, realizando un abordaje deltopectoral y reinsertando el tendón del pectoral mayor con tres dispositivos de anclaje endocortical. Conclusión: La rotura del pectoral mayor es una lesión típica de pacientes jóvenes activos con una incidencia creciente. Aunque no se han evidenciado diferencias significativas entre las distintas opciones de reparación, en nuestra experiencia la utilización de dispositivos de anclaje endocortical aporta unos resultados muy satisfactorios.

Metaphyseal sleeves as the primary implant for the management of bone defects in total knee arthroplasty after post-traumatic knee arthritis.

BACKGROUND: Implantation of a prosthesis after post-traumatic knee arthritis poses challenges derived from the bone defects and soft tissue damage. The objective of this study was to evaluate the clinical and radiological results of the use of metaphyseal sleeves in primary total knee arthroplasty surgery after post-traumatic arthritis. METHODS: Clinical and radiological results of 25 patients undergoing surgery for post-traumatic knee arthritis were prospectively evaluated. A semi-constrained, mobile platform prosthesis with metaphyseal sleeves was implanted. American Knee Society scales, Western Ontario and McMaster Universities Arthritis Index (WOMAC) and the Short Form 12 Health Survey were used. Patients were evaluated at the baseline and at postoperative months three, 12, and annually until final follow-up. RESULTS: The mean follow-up was 79 months with a maximum of 10 years. Mean Knee Society Score (KSS) increased from 29 to 78, and functional KSS from 42 to 81. The average WOMAC pain index changed from 12 to three; average WOMAC stiffness improved from four to one, and WOMAC function score improved from 44 to 16. The mean physical SF12 varied from 30 to 46, while mental SF-12 varied from 45 to 55. Radiological osseointegration of the implants was considered optimal in all cases, with a survival of 100%. CONCLUSIONS: Metaphyseal sleeves in combination with varus-valgus constrained (VVC) components and a rotating platform, have shown good clinical and radiological results in patients with post-traumatic knee arthritis and constitute a reliable alternative for treatment of this disease when the epiphyseal zone is deteriorated and has bone defects.
