The aim of this study was to investigate the correlation of tendon integrity following open cuff repairs with functional and isokinetic strength measurements. Twenty-six shoulders of 25 patients were included in this study. At the final follow-up, 14 repairs (53.8%) were intact and 12 repairs (46.2%) had failed on magnetic resonance imaging (MRI). Mean UCLA score at latest follow-up was 28.5 and mean Constant score was 80.3. Constant scores were found to be significantly low for the failed group. Age was found to be significantly related to failed repair. Fatty infiltration stage in the failed repair group was significantly high, and a strong positive correlation for both groups existed pre and postoperatively. When both groups were compared, the failed group was found to have significantly low measurements at extension and internal rotation. Despite high failure rates, functional results were satisfactory. Increased age and fatty infiltration stage decrease success.

Thirty-six female Sprague-Dawley rats were divided into two groups: oophrectomised (oestrogen deficient) rats and sham operated (oestrogen maintained) rats. Rats were sacrificed at six, ten, and 14 weeks. The rats were randomly chosen to have biomechanical evaluation on one side and histological evaluation on the other. Biomechanical testing was performed on an Instron machine to measure peak load. Histological sections were evaluated for cell proliferation, collagen-fibre organisation, fibroblast density, angiogenesis, inflammatory cells, chondroid and osseous metaplasia. Compared with the sham operated group, the oophrectomised group showed a lesser average maximum stress (42.9 N/m 2 versus 33.7 N/m 2 ) at six weeks, which was significant (p<.05). Succeeding weeks showed no significant biomechanical differences between the two groups. The sham operated group showed greater inflammatory response, which was statistically significant (p< 0.05), and also revealed greater cell proliferation and density. The results of this study revealed that endogenous oestrogen may improve healing of the Achilles tendon in rats.

Glomus tumors are benign neoplasms originating from the glomus body. They are most frequently found in the nail bed of the hands, and their occurrence in other parts of the body is rare. A 75-year-old man presented with left anterior knee pain of 30-year history, that became more intense with light touch or clothing and increased in severity despite medical treatment. Physical examination showed a painful, soft, mobile, red-purple colored mass, 2 x 2 cm in size, at the inferior border of the patella. Plain radiographs showed no pathology other than mild degenerative changes. Magnetic resonance imaging revealed a mass lesion, 1.5 x 1.1 x 2 cm in size, located at the anterior border of the patellar tendon, which showed hypointensity on T1A-weighted sequences and hyperintensity on T2-weighted sequences and T2-weighted sequences with fat saturation. The mass was excised and the histopathological diagnosis was reported as glomangioma. Postoperatively, the patient had no complaint of pain and no recurrence was observed during a two-year follow-up.

This technique was a good treatment alternative for patients with end-stage hallux rigidus. It was a safe and reliable procedure that preserved range of motion and has good outcomes.

Iliosacral screws are superior to bilateral S1 pedicle fixation through posterior tension band plating. However, the combination of tension band plating with iliosacral screw fixation does not improve the stability of the posterior pelvic ring.
