Morbidity and mortality rates are higher in patients with a completely unstable pelvic ring injury. Emergency department stabilization and reconstruction of the pelvic ring with optimal operative techniques in these patients can reduce morbidity and mortality rates. Anterior and posterior internal fixation results in satisfactory clinical and radiologic outcomes. The affective status of patients is an important aspect that should be considered during the entire care of the patient.

The results following primary and delayed primary repair in zone 2 flexor tendon injuries were evaluated prospectively in 88 fingers of 71 patients using two different early postoperative mobilization programmes. In 33 patients, the Kleinert rubber band passive flexion method was used. In the remaining 38 patients, the early active mobilization programme was used. All patients were reviewed 1 year after operation and the results assessed by the Strickland criteria. During this evaluation maximum grip strength was also measured. The results were excellent or good in 78% of digits and mean grip strength was 84% of the uninjured hand in the Kleinert rubber band passive flexion group. In the early active mobilization group, excellent or good results were achieved in 85% of the digits and the mean grip strength was 90% of the uninjured hand. There were two early ruptures in each group.

The aim of this study was to evaluate the effect of SH (sodium hyaluronate-NaHA) on vascular endothelial growth factor (VEGF) and type IV collagen expression during the Achilles-tendon healing process. Adult New Zealand white rabbits (n=32) aged 4 months and weighing 2.7-3.9 kg were used. The rabbits were randomly divided into two groups, and each group was divided into two subgroups and monitored for 6 and 12 weeks. Tendo calcanei were incised transversely and repaired. An injection of 0.5 ml NaHA (15 mg/ml) was administered between the tendon and paratenon of the right leg and repeated twice at one-week intervals. Equal numbers of animals were sacrificed at the 6th and 12th weeks, and the repaired tissue was examined macroscopically and histologically for the presence of VEGF and type IV collagen expression every week. The decrease in the amount of adhesion tissue and the acceleration of tendon healing in the NaHA group were significantly high when compared with control groups at 6 and 12 weeks (p<0.001, p<0.05). In the NaHA group, due to vascular proliferation VEGF immunostaining was strongly positive in the 6th week (p<0.05), and remained positive in the 12th week (p<0.05). Similar immunostaining findings were detected for type IV collagen in the 6th week. However, there was a significant decline in immunostaining rate in the 12th week (p<0.05). The increases in VEGF and type IV collagen expression following SH administration might be an indication that SH may partly be involved in regulation of angiogenesis.
