STUDY OF FUNCTIONAL OUTCOME IN DISPLACED BIMALLEOLAR FRACTURE TREATED WITH FIBULAR PLATING FOR LATERAL MALLEOLUS AND PINNING OR SCREW FOR MEDIAL MALLEOLUS

Fractures of the ankle joint are among the commonest fractures in adults, with an incidence of up to 174 cases per 100 000 persons per year1. A study was conducted to learn the functional outcome of displaced bimalleolar fracture treated with ?bular plating for lateral malleolus and pinning or screw for medial malleolus. For a good long-term functional outcome to be achieved, reliable early evaluation is crucial so that it can be determined whether the problem is a distortion (sprain), ligament rupture, bony ligament avulsion, or fracture of the talocrural joint. The proper treatment is chosen on the basis of the mechanism of the accident and the correct classi?cation of the injury and accompanying soft-tissue damage. The goal of treatment is to enable the patient to put his or her full weight on the joint once again without pain and to prevent permanent damage2. In this study, a total of 25 patients were included. Detailed history and clinical ?ndings are con?rmed and noted. After surgery patients followed on at 1 month, 3 months & 6 months, and thereafter yearly for their radiological and functional outcome

Medial malleolus malunion with secondary tibiotalar and syndesmotic incongruence - two case reports and «box resection¼ for its treatment / Mal unión del maléolo medial con incongruencia tibiotalar y sindesmótica: «resección en caja¼ para su tratamiento

Abstract: Introduction: Ankle fractures are among the most common injuries treated by orthopaedic surgeons. Malunion is one of the possible complications, and corrective surgery is often used to avoid long-term disability. However, few studies address medial malleolus malunion and the best revision surgery technique is controversial. We describe a new surgical technique, the «box resection¼. Material and methods: We present two cases of medial malleolus malunion with secondary talus lateral translation and syndesmotic incongruence. In order to restore a congruent tibiotalar joint, we performed the described technique. Results: We record significant improvement of AOFAS Score and range of motion in both cases, with resolution of pain symptoms. Postoperative radiographs show a congruent mortise with syndesmosis reduction. Conclusion: The box resection allowed immediate talus medial translation to its original position. It is a simple and effective solution, with a good functional outcome.

Resumen: Introducción: La consolidación viciosa del maléolo interno es una posible complicación en las fracturas maleolares. Su tratamiento es difícil y controvertido, por el momento no hay una solución estándar. Proponemos una nueva técnica quirúrgica para el tratamiento de estos casos que denominamos «resección en caja¼. Material y métodos: Presentamos dos casos de consolidación viciosa del maléolo interno, asociados con traslación lateral del astrágalo y incongruencia de la sindesmosis, donde aplicamos la técnica quirúrgica descrita. Resultados: En ambos casos, obtuvimos una mejora significativa en el puntaje AOFAS y en el rango de movilidad, así como en la resolución de las molestias por dolor. Las radiografías muestran mortajas congruentes y anatómicas, con una reducción satisfactoria de la sindesmosis. Conclusión: La técnica de «resección en caja¼ es simple y eficaz produciendo un buen resultado clínico y funcional.

A study on the application of the bran-new method of sampling and forensic for the identification of electrocution: 23 cases analysis / 中国法医学杂志

Objective To confirm the optimal tissue sampling location of current injury combined with the histopathological observation in specific parts of electrocution based on previous animal experiments. Methods Twenty-three human cases from the autopsy through the hand-to-foot circuit pathway were analyzed. Additional ten autopsy patients who died from traffic accidents and sudden cardiac attacks were used as the control group. All cases were extracted the soft tissues from the upper anterior wrist and medial malleolus to further observe and analysis the L/S axis ratio of the nuclei of the skeletal muscle cells (SkMCs) and artery smooth muscle cells (ASMCs). Results The age of the 23 eligible electrical deaths ranged from 19 to 59 years, including 19 cases were male and 4 cases were female. 3 cases were high-voltage 20 cases were low voltage. The occurrence rate of electric marks averaged 31.18% in all cases. The incidence of the classical arborizing pattern of fine branching was 36.4%, appearing on the pleura in 5 cases (22.7%). The nuclei of the SkMCs and ASMCs nuclei in the anterior wrist and medial malleolus within the electrical current pathway were obviously stretched, narrowed, and coalesced, presenting a nuclear polarization and arranging as line-like and moniliform patterns. The L/S axis ratio of those nuclei in the anterior wrist and medial malleolus were markedly increased as compared with the control group (p < 0.001). Through the ROC curve analysis, the critical diagnostic values of the L/S axis ratio of those nuclei were respectively 4.84 and 3.81. Conclusion These findings suggest that the soft tissues of the anterior wrist and/or the medial malleolus, as the narrowest parts of the limbs, could be used as the sites for tissue sampling and considered as necessary locations for histopathological examinations to determine the electrocution in medicolegal identification.

Medial Malleolar Insufficiency Fracture of the Ankle in an Elderly Patient with Osteoporosis

Insufficiency fracture is a type of stress fracture, which is the result of normal stresses on abnormal bone. Postmenopausal osteoporosis is the most common cause of insufficiency fractures. An early diagnosis is best made with a bone scan or magnetic resonance imaging, as radiographs may initially appear normal. Insufficiency fractures of the lower leg and ankle are less common. Furthermore, reports of medial malleolar insufficiency fracture without any history of trauma in elderly patients are extremely rare. Thus, we report a case with a medial malleolar insufficiency fracture of the ankle in an elderly patient with osteoporosis. This case shows that we should be aware of the possibility of encountering an uncommon medial malleolar insufficiency fracture as a cause of pain in the ankle region of an elderly patient with osteoporosis.
