Chronic Posttraumatic Instability of the Distal Radioulnar Joint: Foveal Reattachment of the Triangular Fibrocartilage Complex With Dorsal Capsuloplasty and Extensor Retinaculum Imbrications

Background: The purpose of this article is to describe the surgical technique used by the authors and the outcome in the treatment of chronic posttraumatic instability of the distal radioulnar joint (DRUJ). Methods: A retrospective study was conducted analyzing the medical records of 11 patients with chronic posttraumatic instability of the DRUJ, treated by a foveal reattachment of the triangular fibrocartilage complex with dorsal capsular and extensor retinaculum imbrications between 2016 and 2017, with a follow-up evaluation of 1 year. Results: All patients reported pain relief and the absence of instability, returning to normal activities in 3 to 6 months. Disabilities of the Arm, Shoulder, and Hand (DASH) questionnaire ranged from 2 to 25, resulting in a mean score of 9.5. Forearm rotation averaged 89° of pronation and 85° of supination. Conclusion: Foveal reattachment of the triangular fibrocartilage complex with dorsal capsular and extensor retinaculum imbrications is an effective surgical procedure for the treatment of DRUJ chronic posttraumatic instability.

Role of risk factors in development of chronic posttraumatic instability of ankle joint

Injuries of the ankle joint (AJ) are the most common traumas of musculo-skeletal apparatus and a common reason for seeking medical advice. Overstrains of the ligament apparatus of AJ are the most common mechanism of traumas in running, sporting activity, in unexpected fallings into rough surfaces or getting with a heel into ribbed coverings of metroescalators, in a sharp stoppage of public transport, in wearing footwear on high heels, etc. 20-40% Of patients develop a clinical presentation of a chronic instability of the ankle joint. In the article the analysis of the literature data on the role of risk factors in development of a chronic posttraumatic instability of the ankle joint is given. In result the authors make the conclusion that the influence of the internal risk factors on development of a chronic posttraumatic instability of the ankle jointis studied insufficiently, and further investigations in this direction are required. This scientific trend is important and is of high practical significance, since its results could be used for elaboration of the algorithm of organ-saving operations which will permit to optimize medico-surgical approach, to reduce the number of patients with disability and to return patients to their professional and sporting activity.

The use of inside-outside screws for occipitocervical fusion in pediatric patients

Object The authors describe the use of inside-outside occipital screws in 21 children with occipitocervical instability requiring occipitocervical fusion. Methods The ages of the patients were from 2 to 15 years, and patients presented with a variety of causes of occipitocervical instability, including congenital disorders, posttraumatic instability, idiopathic degeneration, and postoperative instability. Surgeries frequently included foramen magnum decompression, duraplasty, and laminectomy, but all patients required occipitocervical instrumentation and arthrodesis. Postoperative orthosis included the use of either a cervical collar or halo device. In all but one case, patients were followed postoperatively for at least 12 months. Results The mean age of patients was 9.93 years. Inside-outside screws were used in all reported cases. Rib autograft was used in all patients. In addition, demineralized bone matrix was used in 2 cases, and bone morphogenetic protein was used in 2 patients. Two patients required halo placement, and the other 19 were placed in cervical collars. The average time postoperative orthotics were used was 2.82 months. Arthrodesis was determined radiographically and was noted in all patients. No operative complications were noted; however, postoperative complications included 1 wound infection, 2 cases of hardware loosening, and the need for tracheostomy in 2 patients. Conclusions Inside-outside screws were found to be a useful component of occipitocervical instrumentation in pediatric patients ranging from 2 to 15 years of age. Arthrodesis was demonstrated in all cases.

Solution for the Problem of Difficult Respiratory Tract in Planned Orthopaedic Surgery

Methods to solve the situation of difficult intubation in planned orthopaedic surgery are presented. Total number of 101 patients with problematic conventional tracheal intubation due to various orthopaedic pathology (Bekhterev's disease, abnormality of development or posttraumatic instability of cervical spine, etc.) was studied. In 49 patients tracheal intubation was performed using laryngeal mask LMA C-Trach with videovisualization (main group), in 52 patients - using fiberoptic bronchoscope (control group). The results achieved showed high efficacy of LMA C-Trach technology for solving difficult intubation problem. Application of laryngeal mask was successfully performed even in patients with Hallo-apparatus fixed cervical spine. Unlike fiber bronchoscope insertion placing of laryngeal mask was atraumatic in relation to stomatopharynx and enabled to perform adequate pulmonary ventilation till tracheal intubation. Videovisualization ensured accurate localization of trachea and its intubation with atraumatic reinforced tube under visual control. Only in 2 patients use of that technology failed and it was related to the bleeding from tonsils after multiple unsuccessful attempts of trachea intubation using direct laryngoscopy. Above described technique is not only a highly effective method for solving the problem of difficult intubation but decreases psychologic strain of the anesthesiologic team.
