The aim of this study was to investigate the difference in functional outcome after repair and non-repair of the pronator quadratus muscle in patients undergoing surgical treatment for a distal radial fracture with volar plating. A total of 72 patients with a distal radial fracture were included in this randomized clinical trial. They were allocated to have the pronator quadratus muscle repaired or not, after volar locked plating of a distal radial fracture. The patients, the assessor, the primary investigator, and the statistician were blinded to the allocation. Randomization was irreversibly performed using a web application that guaranteed a secure and tamper-free assignment. The primary outcome measure was the Patient Rated Wrist Evaluation (PRWE) after 12 months. Secondary outcomes included the Disabilities of the Arm, Shoulder and Hand (DASH) score, pronation strength, grip strength, the range of pronation and supination, complications, and the operating time.Aims
Patients and Methods
Wrist block has been used to provide pain relief
for many procedures on the hand and wrist but its role in arthroscopy
of the wrist remains unexplored. Chondrotoxicity has been a concern
with the intra-articular infiltration of local anaesthetic. We aimed
to evaluate and compare the analgesic effect of portal and wrist
joint infiltration with a wrist block on the pain experienced by
patients after arthroscopy of the wrist. A prospective, randomised, double-blind trial was designed and
patients undergoing arthroscopy of the wrist under general anaesthesia
as a day case were recruited for the study. Levo-bupivacaine was
used for both techniques. The effects were evaluated using a ten-point
visual analogue scale, and the use of analgesic agents was also
compared. The primary outcomes for statistical analyses were the
mean pain scores and the use of analgesia post-operatively. A total of 34 patients (63% females) were recruited to the portal
and joint infiltration group and 32 patients (59% males) to the
wrist block group. Mean age was 40.8 years in the first group and
39.7 years in the second group (p >
0.05). Both techniques provided
effective pain relief in the first hour and 24 hours post-operatively
but wrist block gave better pain scores at bedtime on the day of
surgery (p = 0.007) and at 24 hours post-operatively (p = 0.006). Wrist block provides better and more reliable analgesia in patients
undergoing arthroscopy of the wrist without exposing patients to
the risk of chondrotoxicity. Cite this article:
The osteoinductive properties of demineralised
bone matrix have been demonstrated in animal studies. However, its therapeutic
efficacy has yet to be proven in humans. The clinical properties
of AlloMatrix, an injectable calcium-based demineralised bone matrix
allograft, were studied in a prospective randomised study of 50
patients with an isolated unstable distal radial fracture treated
by reduction and Kirschner (K-) wire fixation. A total of 24 patients
were randomised to the graft group (13 men and 11 women, mean age
42.3 years (20 to 62)) and 26 to the no graft group (8 men and 18
women, mean age 45.0 years (17 to 69)). At one, three, six and nine weeks, and six and 12 months post-operatively,
patients underwent radiological evaluation, assessments for range
of movement, grip and pinch strength, and also completed the Disabilities
of Arm, Shoulder and Hand questionnaire. At one and six weeks and
one year post-operatively, bone mineral density evaluations of both
wrists were performed. No significant difference in wrist function and speed of recovery,
rate of union, complications or bone mineral density was found between
the two groups. The operating time was significantly higher in the
graft group (p = 0.004). Radiologically, the reduction parameters
remained similar in the two groups and all AlloMatrix extraosseous leakages
disappeared after nine weeks. This prospective randomised controlled trial did not demonstrate
a beneficial effect of AlloMatrix demineralised bone matrix in the
treatment of this category of distal radial fractures treated by
K-wire fixation. Cite this article:
