We present the case of a young patient with a severely comminuted, malunited, intra-articular distal radius fracture and complete disruption of the sigmoid notch. We reconstructed the malunited distal radioulnar joint by osteotomy and repositioning the displaced sigmoid notch fragments through a combined dorsal and volar approach. At the same time, we carried out a radioscapholunate arthrodesis...

The management of osteoarthritis of the knee associated with patellar instability secondary to external tibial torsion > 45 degrees is challenging. Patellofemoral biomechanics in these patients cannot be achieved by intra-articular correction using standard techniques of total knee replacement. We reviewed seven patients (eight knees) with recurrent patellar dislocation and one with bilateral i...

background:   various drugs are administered intra-articularly to provide postoperative analgesia after arthroscopic knee surgery. the purpose of this study was to assess the analgesic effects of intra-articular injection of a dexmedetomidine   following knee arthroscopy.     methods:   forty six patients schadualed for arthroscopic knee surgery under general anaesthesia, were randomly devided ...

background: arthroscopic intervention is very common for conducting orthopedic surgeries. after a knee arthroscopic surgery, different drugs are used through intra-articular administration to induce analgesia. the aim of this study was to evaluate analgesic effects of bupivacaine (marcaine), bupivacaine plus midazolam, and bupivacaine plus fentanyl in reducing pain after knee arthroscopic surge...

Treatment of traumatic hip dislocation can be conservative one with closed reduction, made within 48 hours of the accident, or surgical one. Surgical therapy includes many techniques, which are divided on intra and extra-articular ones. Among surgical procedures practice in hip luxation in dogs are: prosthetic capsule repair, joint capsule imbrication, transposition of greater trochanter, prost...

A method of making a visual display of subchondral mineralization in the major synovial joints is described. Unlike existing procedures, it can be used on the living subject. A modified application of computed tomography-densitometry, computed tomography-osteoabsorptiometry makes it possible to explore the mechanical adaptability to the prevailing mechanical force. This claim is based upon the ...

The progression of gonarthrosis results in reduction of physical activity. One of the factors that increase the risk of osteoarthrosis may be joint overload related to the malalignment of the mechanical axis of the lower extremity. The medial compartment (MC) of the knee is particularly susceptible to overload due to the external knee adduction moment (EKAM). Varus knee malalignment contributes...

Malunion of a proximal humerus fracture is difficult to manage once bone union has been achieved in a wrong position. Malunion may be encountered after conservative treatment or internal fixation of fractures, and also around a joint prosthesis. The malunion can involve the greater and lesser tuberosities, humeral head, bicipital groove, or the entire epiphysis. The nature of the malunion must ...

Background:Chronic synovitis is one of the most important complications in haemophilic patients. Rifampin is anantibiotic which its intra-articular injecion leads to destruction of the synovial membrane of haemophilic patientsmedically.Materials and Methods: Between September 2003 and November 2005, we administered intra-articular rifampinin ١۶ haemophilic joints of ٨ haemophilic patients.Resul...
