Flexor Digitorum Avulsion Secondary to Enchondroma of the Distal Phalanx / 대한정형외과학회잡지

This case report describes the unusual occurrence of a flexor digitorum profundus avulsion secondary to an enchondroma of the distal phalanx of the middle finger. The enchondroma was treated by simple curettage with an autogenous bone graft harvested from the olecranon. The avulsed bone fragment was reattached to the distal phalanx using the pull-out suture technique. Bony union and full function of the digit were achieved.

Full Cementation in Revision Total Knee Arthroplasty Using a Constrained Condylar Knee Prosthesis with an Average 7-Year Follow-up

PURPOSE: To evaluate clinical and radiological outcome of the full cementation technique in revision total knee arthroplasty (TKA) using a constrained condylar knee (CCK) prosthesis. MATERIALS AND METHODS: Between January 2008 and March 2012, 18 cases (16 patients) of fully cemented revision TKA were performed using a CCK prosthesis. Fifteen cases of aseptic loosening (13 patients) and 3 cases of infection were included. There were 2 males and 14 females with a mean age of 76.7 years at the time of surgery, and the average follow-up was 81 months. Clinically, the pain score, function score and Hospital for Special Surgery (HSS) score were evaluated. Radiologically, loosening, radiolucent lines and migration of implant were evaluated. RESULTS: Preoperatively, the pain score, function score and HSS score were 50.3, 24.4 and 61.8 points, respectively. At the latest follow-up, the scores were improved to 84.8, 63.6 and 85.6 points, respectively (p < 0.05). Loosening or migration of implant was not observed in any cases. Radiolucent lines were observed in 5 cases underneath the tibial component without progression during the follow-up. CONCLUSIONS: The full cementation technique in revision TKA using a CCK showed excellent clinical results. Although radiolucent lines were observed in 27.8% underneath the tibial component, there was no progression to loosening or instability.
