This study aimed to determine if the adoption of collagenase treatment is economically viable.

Xiapex collagenase was trialled at Gloucestershire Hospitals NHS Trust in 50 patients suitable for fasciectomy, with a palpable cord and up to two affected joints. Retrospective data for contracture angle pre-injection, immediately post-manipulation and at an average 6 weeks (range 2–17) clinic follow up was collected from medical notes. At follow up the post-procedure number of days required for return to activities of daily living (ADLs) and/or work were recorded, along with overall patient satisfaction rating.

Complete data was obtained for 43 patients of average age 67 (range 45–82). At follow up 88% had ≤ 20° residual contracture. Average days return to full ADLs was 9 and work was 11. Overall satisfaction was 8.6 out of 10. Xiapex patients required an average 1 hand physiotherapy appointment post-manipulation compared to 6 for fasciectomy, saving £172.20. Total cost for one treatment course, excluding physiotherapy, was £1166 for Xiapex compared to £2801 for palmar fasciectomy and £5352 for digital fasciectomy.

The level of contracture after one Xiapex treatment course permitted return of hand function in the majority of patients whose overall treatment course required less financial and hospital resources.

Aim: Subtle intra-articular screw penetration of the distal radius during fracture fixation is difficult to determine using standard PA and lateral radiographs. The purpose of our study was to determine which radiographs most reliably identify penetration into the joint.

Methods: A distal volar locking plate was applied to an isolated cadaveric radius bone and a series of plain radiographs taken. The radius, fixed along its long axis, was allowed to rotate through 180 degrees and inclined, in increments, to 40 degrees. In the control group the distal screws did not breach the articular surface. In the study group the screws penetrated the articular surface by 1mm. In each group 65 plain radiographs were taken and the presence or absence of screw penetration scored by two blinded observers.

Results: Using Weighted Kappa analysis the overall inter-observer agreement for all views was 0.5 (CI 0.39 –0.63). However in 7 radiographs there was complete inter-observer agreement correctly identifying screw penetration of the articular surface. The articular surface was correctly identified as intact in 13 views. Only a 75 degrees pronated view, without inclination, was 100% sensitive and specific for identifying the absence or presence of screw penetration through the articular surface.

Conclusion: The intra-operative use of a 75 degrees pronated view may reduce the need for repeated use of the image intensifier and excessive irradiation during plate fixation of distal radius fractures.
