The purpose of the study was to compare clinical and radiological outcomes of autografts obtained from the iliac crest (IC) and distal radius (DR) and to evaluate their superiority for surgical treatment of solitary finger enchondromas.Twenty-five patients for whom curettage and autografting were carried out for finger enchondroma were retrospectively analyzed. DR autograft was used in eight patients and IC autograft was used in 17 patients. Data on pre-operative total active motion (TAM), disabilities of the arm, shoulder, and hand (DASH) score, and pain visual analog scale (VAS) scores of the involved finger, duration of surgery, amount of bleeding during the operation, length of hospital stay, presence of complications related to anesthesia, and post-operative donor site morbidity were obtained. Pre-operative and post-operative 12No statistically significant difference could be identified between post-operative TAM (p=0.154), DASH (p=0.458), pain VAS scores (p=0.571), remnant volume (p=0.496), Tordai radiologic evaluation grade (p=0.522), duration of surgery (p=0.288), and amount of bleeding (p=0.114) between DR and IC groups. However, mean hospital stay duration was shorter for the DR group (p=0.0001). Recurrence was observed in one patient in the DR group and three patients in the IC group (p=0.996).The clinical and radiological outcomes of grafting from the DR and IC were similar in the treatment of hand enchondromas. However, grafting from the DR may result in shorter hospital stay compared to IC grafting.

Aim: To examine whether the application of intra-articular lavage during arthroscopic joint fracture surgery can disturb fracture union and cartilage healing. Metods: Twenty New Zealand rabbits were then randomly divided into 3 groups; these groups consisted of 2 surgical groups including eight rabbits and a control group consisting of 4 rabbits. After both rear limbs exposed with a medial parapatellar incision, medial femoral condyle was fractured. Four groups were created by doing anatomic reduction or non-anatomic reduction and making irrigation or no irrigation. (Group 1: Fixed by creating a gap and no Irrigation; Group 2: Fixed by creating a gap and irrigation; Group 3: Fixed with complete reduction and no irrigation; Group 4: Fixed with complete reduction and irrigation) X-rays of both knees of all rabbits were taken at the end of the second week and at the end of the eighth week. The operated knees were collected for histopathological analysis. Results: Radiological data show a significant difference in the level of ossification between the groups in the 2nd week; however, this difference was lost in the 8th week. Histopathologically, at the end of week 8, it was observed that the subchondral bone tissue was incompletely renewed in all the groups. The cartilage tissue of the joint surface was not fully formed and renewed and that it did not completely coalesce with the old cartilage tissue in all of the groups. Compared with the other groups, the group that fracture was anatomically reducted with no irrigation (Group 1), the cartilaginous tissue layer formed was thicker while the surface of the tissue was flatter. Conclusion: There were no adverse effects of intra-articular lavage on fracture union and cartilage healing in an in vivo environment. Nonetheless, the findings of this study should be confirmed with a larger sample size.
