A retrospective review was conducted of patients undergoing either total hip replacement or hemiarthroplasty for intra-capsular neck of femur fractures between April 2013 and April 2014; identified from entries into the National Hip Fracture Database. PACS and the electronic database encompassing operation notes and discharge summaries were reviewed. 309 patients were identified, 3 of whom fractured both hips during the study period giving a total of 312 operations. The age range was 46 to 102 with a mean age of 82. 59 cemented bipolar hemiarthroplasties, 143 cemented unipolar hemiarthroplasties, 2 uncemented hemiarthroplasties and 108 total hip replacements were performed. 10 patients required further operations. There have been 5 dislocations: 2 underwent MUA only, 2 treated by excision arthroplasty and 1 converted to THR. 1 patient developed a haematoma requiring wound washout. There were 4 wound infections - 1 treated by a washout, 2 by excision arthroplasty and one patient has undergone first stage revision; an overall reoperation rate of 3.2% comparing well with data published elsewhere.
The RR was significantly higher in men than in women after wrist fracture (p=0.002), but not after spine fracture (p=0.12).
Three palmar wrist ligaments from fresh human cadavers were dissected from the proximal to the distal insertions and stained to identify the mechanoreceptors. Golgi organs, Pacinian corpuscles, Ruffini endings and free nerve endings were present in all three ligaments. In the radial collateral and radiolunate ligaments they were found in increased density towards the proximal and distal insertions. A more uniform distribution was found in the radioscaphocapitate ligament which has attachments to three bones. The palmar wrist ligaments may have a significant sensory role in maintaining the stability of the wrist and in controlling its movement. Although technically difficult, the surgical repair of traumatic wrist defects should attempt to preserve the innervation of the ligaments, shown to be mainly near bony attachments. This may allow improvement in postoperative outcomes by preserving some proprioception. In some painful post-traumatic or degenerative conditions, however, denervation may be advantageous.
