Arthroscopic Treatment of Chronic Acromioclavicular Dislocation With Semitendinosus Autograft and Coracoclavicular Suspension Fixation.

The management of acromioclavicular dislocations remains controversial. On many occasions, these chronic dislocations are asymptomatic. However, there are patients who, despite good rehabilitation treatment, do present with pain, periscapular muscle fatigue, weakness, paresthesia or scapular dyskinesia. In these patients, surgical treatment is indicated.

Fixation of olecranon osteotomy only with 6'5 mm partially trheaded cancellous screw is a safe an effective method used in surgical management of distal humerus fractures.

PURPOSE: The objective of this study is to demonstrate the safety and efficacy of the osteosynthesis with a 6.5 mm screw and washer of a Chevron shape olecranon osteotomy performed for the surgical approach of supraintercondylar fractures of the distal humerus, achieving union and complication rates better or similar to other published case series. METHODS: From 2009 to 2019, 26 patients underwent fixation of an olecranon osteotomy for the treatment of a supraintercondylar fracture of the distal humerus with partially threaded cancellous cannulated screws of 6.5 mm diameter with a washer. The patients were followed for at least 1 year, taking radiographs the day after the surgery, at 3, 6 and 12 months. Complications have been collected: infection, loss of reduction, non-union, delay of union, discomfort of the osteosynthesis hardware. The diameter of the ulna medullary canal diaphysis was also measured in all patients. RESULTS: Consolidation of the osteotomy was 100% at 12 months. The average time of radiological consolidation was 112 ± 12 days. The average size of the ulna medullary canal diaphysis was 6'06 ± 0'16 mm on anteroposterior radiographs and 5'65 ± 0'14 mm on lateral radiographs. The mean screw length was 102'31 mm ± 3'89. We found 1 acute infection, 2 osteotomies delays of union (one of these cases was the acute infection case), one early osteosynthesis failure and 1 wound dehiscence. CONCLUSIONS: Olecranon ostetomy fixation with a 6'5 mm cancelous partial threaded screw and washer is safe and effective with a high consolidation rate and excellent results and with complication rates similar to or lower than other fixation methods published. Long enough screws must be used to get a good cortical grip with enough stability. LEVEL OF EVIDENCE: Level IV, Case series, retrospective review.

Necesitamos revisar las heridas en dorso de mano y antebrazo / Nécessité de la mise en charge des blessures du dos de la main et l'avant-bras / It is necessary to inspect the wounds in hand dorsum and forearm

INTRODUCCIÓN: Las lesiones en dorso de mano son urgencias frecuentes de un hospital. Estudiar la relación existente entre la clínica inicial y la afectación tendinosa subyacente en heridas localizadas en esta región. Así como valorar la localización exacta, tipo, y etiología de ellas, por medio de un estudio observacional. MÉTODOS: Se realizó un estudio transversal, en el que se valoran 51 pacientes con 55 heridas en dorso de mano y antebrazo, tratadas en urgencias de nuestro hospital durante el periodo de junio a diciembre de 2009. RESULTADOS: La exploración inicial nos ofrece una especificidad y un valor predictivo positivo del 100 por ciento, pero una sensibilidad del 17,14 por ciento y un valor predictivo negativo del 40,81 por ciento con respecto a la presencia de lesión tendinosa. CONCLUSIÓN: Ante la falta de correlación entre la clínica inicial con una posible lesión tendinosa extensora recomendamos la exploración quirúrgica de las heridas en dorso de mano, por su sencillez y aprovechamiento del acto quirúrgico(AU)

INTRODUCTION: Injuries in hand dorsum are frequent hospital emergences. It is necessary to study the relation between initial clinics and the tendinous injuries underlying in wounds present in this region, as well to assess its exact location, the type and etiology through observational study. METHODS: A cross-sectional study was conducted to assess 15 patients presenting with wounds in the hand dorsum and forearm, treated in emergency room of our hospital from June to December, 2009. RESULTS: The initial screening offer us a specificity and a positive predictive value of the 100 percent, but a sensitivity of 17,4 percent and a negative predictive value of 40,81 percent regarding the presence of the tendinous injury. CONCLUSION: Due to a lack of correlation between the initial clinics and a possible extensor tendinous injury, it is recommended the surgical exploration of hand dorsum injuries due to its simplicity and use of surgical act(AU)

INTRODUCTION: Les lésions du dos de la main sont des urgences fréquentes d'un hôpital. Le but de cette étude est d'étudier la relation existant entre la clinique initiale et l'affection tendineuse sous-jacente des blessures localisées à cette région, et d'évaluer la localisation exacte, le type et l'étiologie par une étude observationnelle. MÉTHODES: Une étude transversale, portant sur 51 patients atteints de blessures (55) au dos de la main et l'avant-bras, et traités au service des urgences de notre hôpital entre juin et décembre 2009, a été réalisée. RÉSULTATS: L'exploration initiale nous montre une spécificité et une valeur pronostique positive de 100 percent, mais une sensibilité de 17,14 percent et une valeur pronostique négative du 40,81 percent par rapport à la présence des lésions tendineuses. CONCLUSIONS: Devant l'absence de corrélation entre la clinique initiale et une possible lésion du tendon extenseur, il est conseillé de faire une exploration chirurgicale des blessures du dos de la main, car elle est simple et très utile(AU)
