A retrospective review of 51 consecutive patients undergoing fixation of Scaphoid fractures by two surgeons in a single institution was conducted. Twenty-four patients were treated with a Herbert screw and twenty-seven with an Acutrak screw. This included six patients who underwent acute fixation, three in each group. The remaining cases were for the treatment of non-union and delayed union. There were no significant differences between the two groups in terms of age, side of injury, and mechanism of injury. Fractures were classified as proximal, middle and distal thirds of the Scaphoid and there was no significant difference between the groups regarding the types of fractures treated. The only significant difference between the groups was the time from injury to fixation when considering the cases of delayed union and non union which was greater in the Herbert screw group (7.5 months vs 4 months p=<0.05). There was no significant difference in outcome between the two methods of fixation. Union rates for all cases were 79% for Herbert screws and 81% for Acutrak screws and 82% and 83% respectively when only considering the delayed union/non-union procedures. There was no difference in terms of time to union, further surgery or clinical outcome between the two groups. The Acutrak screw required removal in five patients and the Herbert screw in two due to symptoms from screw prominence. This was not statistically significant. In conclusion there is no significant difference in surgical outcome between these two methods of fixation for Scaphoid fractures. The authors feel that this supports the view that biological factors are more important than the method of fixation in obtaining union of Scaphoid fractures.
The indication for revision was aseptic loosening in 16 cases, and deep sepsis in 13 cases, (12 were done in 2 stages). Others included polyethylene wear in 4 knees, instability in 2, and 1 each of peri-prosthetic fracture, implant breakage and pain of undetermined origin. 3 revisions were performed for failed Link Lubinus patello-femoral replacement. Mean interval between staged procedures for sepsis was 2 months. Reconstruction was performed using the Kinemax Revision system with the use of augments and stems. The modular rotating hinge was used in 4 cases. Surgical exposure included additional lateral release in 7 cases, tibial tubercle osteotomy in 4 and quadriceps snip in one.
At latest review, 7 patients had died due to unrelated causes with a pain free functioning knee prosthesis. Of the remaining 31, 26 patients had none or minimal pain. 21 were independently mobile with a satisfactory range of motion.10 patients needed a walking stick.
Aggressive digital papillary adenocarcinoma (ADPACa) is a rare skin adnexal tumour, which has a predilection for the digits. We report a case with this tumour in a 51 year old insulin dependent diabetic man, who presented as a paronychia of right index finger. After histopathological confirmation as an ADPACa partial amputation was performed. This case emphasizes the presentation of this tumour as a simple nail bed infection occasionally.
The AO, Frykman, Mayo and Fernandez classification system for distal radius fractures were evaluated for interobserver reliability and intraobserver reproducibility using plain radiographs. Five orthopaedic consultants, five orthopaedic registras and five orthopaedic senior house officers classified 20 sets of distal radius fractures on two seperate occasions. There were 2400 induvidual observations. Kappa statistics were used to establish a relative level of agreement between observers for the two readings and between seperate readings by the same observer. Our results for intraobserver reproducibility showed Fernandez Kappa value of 0.49, Frykman 0.47, Mayo 0.45 and AO 0.33. A 0.4 result shows good consistecy accorcing to well reconised staistical boundries and is significant. That is reproducibility happened at a level greater than by chance. Interobserver Kappa values were poor in all classification systems. We also sought to look at varibles within grade of surgeon and developed Kappa values for these also.
