This study confirms that fresh frozen human bone allograft cells have the potential to grow in vitro, but the significance of this in recipients is currently unknown.

Delta III prosthesis restores the function in shoulder affected by severe pain and dysfunction due to rotator cuff arthropathy. Inferior scapular notching in the post-operative radiographs was better visualised in abduction views compared with standard anteroposterior radiographs. Long-term follow-up is required to predict the effect of scapular notching.

Disorders of the pisotriquetral joint are well recognised as the cause of pain on the ulnar side of the wrist. The joint is not usually examined during routine arthroscopy because it is assumed to have a separate joint cavity to the radiocarpal joint, although there is often a connection between the two. We explored this connection during arthroscopy and in fresh-frozen cadaver wrists and found that in about half of the cases the pisotriquetral joint could be visualised through standard wrist portals. Four different types of connection were observed between the radiocarpal joint and the pisotriquetral joint. They ranged from a complete membrane separating the two, to no membrane at all, with various other types of connection in between. We recommend that inspection of the pisotriquetral joint should be a part of the protocol for routine arthroscopy of the wrist.

We describe an unusual case of pseudo-aneurysm of the lateral circumflex femoral artery following fixation of an undisplaced intracapsular neck of femur fracture. We highlight the need for a high index of suspicion and the value of angiography as the investigation of choice.
