Introduction. Although Total elbow arthroplasty (TEA) generally provides favorable clinical outcomes, its complications have been reported with high rate compared with other joints. Previously, we used the Bryan & Morrey approach in TEA, which included separating the triceps muscle subperiosteally from the olecranon; however, since 2008, in order to prevent skin trouble and deficiency of the triceps, we performed TEA by MISTEA method, which required no removal of the subcutaneous tissue in the region of the olecranon and no release or stripping of the triceps tendon. Objectives. The purpose of this study was to examine the utility of the MISTEA method by evaluating and comparing muscle strength and complications by using both the Bryan & Morrey approach and MISTEA method. Materials and Methods. The study was conducted on 23 elbows, on which elbow muscle strength could be measured postoperatively at more than 6 months after TEA. Thirteen elbows were operated on the Bryan & Morrey approach (BM group; mean age, 62.3 years; mean follow-up period, 27 months), and 10 elbows on the MISTEA method (MIS group; mean age, 67.6 years; mean follow-up period, 19.1 months). To determine the elbow extensor and flexor strengths, measurements were conducted on the affected side for the BM group, and on both the affected and healthy sides for the MIS group. Further, the “extension/flexion ratio” as well as the “affected/healthy side ratio” and complications were assessed. Results. Excluding the elbow extensor strength of 3 elbows in the BM group, which could not be measured too week. The extension/flexion ratio was as follows: in the BM group, 0.61 and in the MIS group, 0.93 on the affected side and 0.81 on the healthy side. For the MIS group, in which measurements could be performed on both the sides, the “affected/healthy side ratio” was 0.72 in flexion and 0.91 in extension. In terms of complications, skin trouble was found on 2 elbows in the BM group and on 1 elbow in the MIS group; further, rupture of the triceps tendon was suspected in 3 elbows in the BM group but was not found in the MIS group. Discussion. In our study, deficiency in triceps muscle was found in 3 of 13 elbows with the Bryan & Morrey approach. MISTEA method may be the reason for prevention of deficiency or rupture of the triceps tendon. The MIS group had higher extension/flexion ratio in the affected side, suggesting the possibility that either the extensor strength had increased or the flexor strength had weakened. Further, in the MIS group, the extension showed an “affected/healthy side” ratio, which means that an extensor strength almost equivalent to that of the healthy side was maintained, whereas the flexor strength was 72% of that on the healthy side, suggesting that the flexor strength may have decreased. Loss of the flexor strength may be because the MISTEA method involves partial release of the brachialis muscle and the joint's center of rotation to move slightly towards the proximal side

Trans-articular coronal shear fractures of the distal humerus pose a significant challenge to the surgeon in obtaining an anatomical reduction and rigid fixation and thereby return of good function. A variety of approaches have been described which include the extended lateral and anterolateral approaches and arthroscopically-assisted fixation for non-comminuted fractures. Fixation methods include open or percutaneous cannulated screws and headless compression screws directed either anterior to posterior or posterior to anterior. We describe an illustrated, novel approach to this fracture which is minimally invasive but enables an anatomical reduction to be achieved. A 15 year old male presented with a Bryan and Morrey type 4 fracture as described by McKee involving the left distal humerus. He was placed in a lateral position with the elbow over a support. A posterior longitudinal incision and a 6cm triceps split from the tip of the olecranon was made. The olecranon fossa was exposed and a fenestration made with a 2.5mm drill and nibblers as in the OK (Outerbridge-Kashiwagi) procedure. A bone lever was then passed though the fenestration and used to reduce the capitellar and trochlear fracture fragments into an anatomical position with use of an image intensifier to confirm reduction. The fracture was then fixed with two headless compression screws from posterior to anterior into the capitellar and trochlear fragments (see images). Early mobilisation and rehabilitation were commenced. Follow-up clinical examination and radiographs at six weeks revealed excellent range-of-motion and function with anatomical bony union. We believe that this novel approach to this fracture reduces the amount of soft tissue dissection associated with conventional approaches and their associated risks and also enables earlier return to function with restoration of anatomy

Background. There have been limited published reports on the clinical results of cervical artificial disc replacement. Goffin et al reported a 90% rate of good to excellent results at 1 to 2 yrs after Bryan disc replacement. Wigfield et al reported a 46% improvement in pain and 31% improvement in disability 2 yrs after Prestige cervical disc replacement. Objectives. The study was designed to determine whether new functional cervical disc prosthesis can provide improvement in the ability to perform activities of daily living, decrease pain and segmental motion. Methods. All patients who had Prestige cervical disc replacement over last 2yrs 3 months were identified. Oswestry disability index score and SF36 Quality of life instrument were administered to each patient. Site specific pain scores were obtained using visual analogue scale. Clinical and operative details were reviewed and correlated. Results. 35 Patients underwent 48 Prestige cervical disc replacement during study period. There was 48%, 54% and 70% improvement in Oswestry disability index at 6 weeks, 6 months and 19 months follow-ups respectively. There was significant improvements in both neck and arm pain during immediate post op period and during further follow-ups. There was one neck wound haematoma and one left sided Horner's syndrome as complications. Conclusion. Anterior cervical disc replacement is a viable surgical alternative to fusion for cervical disc degenerative disease and herniation with preservation of motion and alignment without compromising clinical outcomes. At least 5yrs follow-up will be needed to assess the long term functionality of the prosthesis and protective influence on the adjacent levels
