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:
There is no consensus on the benefit of arthroscopically
assisted reduction of the articular surface combined with fixation
using a volar locking plate for the treatment of intra-articular
distal radial fractures. In this study we compared the functional
and radiographic outcomes of fluoroscopically and arthroscopically
guided reduction of these fractures. Between February 2009 and May 2013, 74 patients with unilateral
unstable intra-articular distal radial fractures were randomised
equally into the two groups for treatment. The mean age of these
74 patients was 64 years (24 to 92). We compared functional outcomes
including active range of movement of the wrist, grip strength and Disabilities
of the Arm, Shoulder, and Hand scores at six and 48 weeks; and radiographic
outcomes that included gap, step, radial inclination, volar angulation
and ulnar variance. There were no significant differences between the techniques
with regard to functional outcomes or radiographic parameters. The
mean gap and step in the fluoroscopic and arthroscopic groups were
comparable at 0.9 mm (standard deviation Arthroscopic reduction conferred no advantage over conventional
fluoroscopic guidance in achieving anatomical reduction of intra-articular
distal radial fractures when using a volar locking plate. Cite this article:

The Essex-Lopresti injury (ELI) of the forearm
is a rare and serious condition which is often overlooked, leading
to a poor outcome. The purpose of this retrospective case study was to establish
whether early surgery can give good medium-term results. From a group of 295 patients with a fracture of the radial head,
12 patients were diagnosed with ELI on MRI which confirmed injury
to the interosseous membrane (IOM) and ligament (IOL). They were
treated by reduction and temporary Kirschner (K)-wire stabilisation
of the distal radioulnar joint (DRUJ). In addition, eight patients
had a radial head replacement, and two a radial head reconstruction. All patients were examined clinically and radiologically 59 months
(25 to 90) after surgery when the mean Mayo Modified Wrist Score
(MMWS) was 88.4 (78 to 94), the mean Mayo Elbow Performance Scores
(MEPS) 86.7 (77 to 95) and the mean disabilities of arm, shoulder
and hand (DASH) score 20.5 (16 to 31): all of these indicate a good outcome. In case of a high index of suspicion for ELI in patients with
a radial head fracture, we recommend the following: confirmation
of IOM and IOL injury with an early MRI scan; early surgery with
reduction and temporary K-wire stabilisation of the DRUJ; preservation
of the radial head if at all possible or replacement if not, and
functional bracing in supination. This will increase the prospect
of a good result, and avoid the complications of a missed diagnosis
and the difficulties of late treatment. Cite this article:

Most fractures of the radial head are stable
undisplaced or minimally displaced partial fractures without an associated
fracture of the elbow or forearm or ligament injury, where stiffness
following non-operative management is the primary concern. Displaced
unstable fractures of the radial head are usually associated with other
fractures or ligament injuries, and restoration of radiocapitellar
contact by reconstruction or prosthetic replacement of the fractured
head is necessary to prevent subluxation or dislocation of the elbow
and forearm. In fractures with three or fewer fragments (two articular
fragments and the neck) and little or no metaphyseal comminution,
open reduction and internal fixation may give good results. However,
fragmented unstable fractures of the radial head are prone to early
failure of fixation and nonunion when fixed. Excision of the radial
head is associated with good long-term results, but in patients
with instability of the elbow or forearm, prosthetic replacement
is preferred. This review considers the characteristics of stable and unstable
fractures of the radial head, as well as discussing the debatable
aspects of management, in light of the current best evidence. Cite this article:
Arrest of growth of the distal radius is rare but will produce deformity of the wrist. We corrected angular deformity and shortening of the distal radius by epiphysiolysis and gradual lengthening without a corrective osteotomy.
The purposes of this study were to define the range of laxity of the interosseous ligaments in cadaveric wrists and to determine whether this correlated with age, the morphology of the lunate, the scapholunate (SL) gap or the SL angle. We evaluated 83 fresh-frozen cadaveric wrists and recorded the SL gap and SL angle. Standard arthroscopy of the wrist was then performed and the grades of laxity of the scapholunate interosseous ligament (SLIL) and the lunotriquetral interosseous ligament (LTIL) and the morphology of the lunate were recorded. Arthroscopic evaluation of the SLIL revealed four (5%) grade I specimens, 28 (34%) grade II, 40 (48%) grade III and 11 (13%) grade IV. Evaluation of the LTIL showed 17 (20%) grade I specimens, 40 (48%) grade II, 28 (30%) grade III and one (1%) grade IV. On both bivariate and multivariate analysis, the grade of both the SLIL and LTIL increased with age, but decreased with female gender. The grades of SLIL or LTIL did not correlate with the morphology of the lunate, the SL gap or the SL angle. The physiological range of laxity at the SL and lunotriquetral joints is wider than originally described. The intercarpal ligaments demonstrate an age-related progression of laxity of the SL and lunotriquetral joints. There is no correlation between the grades of laxity of the SLIL or LTIL and the morphology of the lunate, the SL gap or the SL grade. Based on our results, we believe that the Geissler classification has a role in describing intercarpal laxity, but if used alone it cannot adequately diagnose pathological instability. We suggest a modified classification with a mechanism that may distinguish physiological laxity from pathological instability.
A total of 179 adult patients with displaced intra-articular fractures of the distal radius was randomised to receive indirect percutaneous reduction and external fixation (n = 88) or open reduction and internal fixation (n = 91). Patients were followed up for two years. During the first year the upper limb musculoskeletal function assessment score, the SF-36 bodily pain sub-scale score, the overall Jebsen score, pinch strength and grip strength improved significantly in all patients. There was no statistically significant difference in the radiological restoration of anatomical features or the range of movement between the groups. During the period of two years, patients who underwent indirect reduction and percutaneous fixation had a more rapid return of function and a better functional outcome than those who underwent open reduction and internal fixation, provided that the intra-articular step and gap deformity were minimised.
