Conservatively treated compressed fractures of the distal radius dorsal metaphysis healed despite primarily good reduction and consequent treatment with a decrease in dorsal length. The amount of this decline depends on the primary loss of dorsal length. If the fracture showed a loss of dorsal length at the time of the accident of up to 2 mm, the long-term results were almost anatomical. If there was primarily a larger loss of dorsal length, a decline of the distal fragment into the dorsal cave resulted. Most of the dorsal length regained after reduction was lost when the cast was removed. The long-term follow-up examinations were made after about 9 years.

Comparative Study
PURPOSE
To evaluate and compare the biomechanic rigidity and strength of 3 fixed-angle plates used to treat extra-articular distal radius fractures that are dorsally unstable. Volar fixed-angle plates were compared with a dorsal fixed-angle nail plate.
METHODS
Three plate constructs were tested: the dorsal nail plate (DNP), distal volar radius (DVR) plate, and locking compression plate (LCP) volar distal radius plate. With anatomic, third-generation, artificial composite radii, dorsally unstable extra-articular distal radius fracture models were made by cutting a wedge osteotomy with an 8-mm dorsal gap 1 cm from the articular surface. These models were then fixed with the 3 implants by the method recommended by the manufacturer. The proximal radii of each specimen were attached to the base of a materials testing machine with a probe centered at the radial side of the lunate fossa. The specimens were loaded at a constant rate to failure under axial compression. Load and displacement were plotted graphically, and the resulting rigidities and strengths of each plate were assessed statistically.
RESULTS
The DVR group had significantly greater stiffness than the LCP group. The DVR group had significantly higher maximum loads than both the DNP and LCP groups. There were no significant differences in yield loads. Both the DNP and DVR groups had significantly less displacement at yield than the LCP group.
CONCLUSIONS
These 3 groups had similar yield loads. However, the LCP was less stiff than the DVR and had more displacement at yield than both the DVR and DNP. The yield load of all 3 implants was much higher than previously described loads for active wrist and finger motion.

Review
PURPOSE
Forearm and distal radius fractures are among the most common fractures in children. Many fractures are definitively treated with closed reduction and casting, however, the risk for re-displacement is high (7% to 39%). Proper cast application and the three-point moulding technique are modifiable factors that improve the ability of a cast to maintain the fracture reduction. Many providers univalve the cast to accommodate swelling. This study describes how the location of the univalve cut impacts the pressure at three-point mould sites for a typical dorsally displaced distal radius fracture.
METHODS
We placed nine force-sensing resistors on an arm model to collect pressure data at the three-point mould sites. Sensory inputs were sampled at 15 Hz. Cast padding and a three-point moulded short arm fibreglass cast was applied. The cast was then univalved on the dorsal, volar, radial or ulnar aspect. Pressure recordings were obtained throughout the procedure.
RESULTS
A total of 24 casts were analyzed. Casts univalved in the sagittal plane (dorsal or volar surface) retained up to 16% more pressure across the three moulding sites compared with casts univalved in the coronal plane (radial or ulnar border).
CONCLUSION
Maintaining pressure at the three-point mould prevents loss of reduction at the fracture site. This study shows that univalving the cast dorsally or volarly results in less pressure loss at moulding sites. This should improve the chances of maintaining fracture reductions when compared with radial or ulnar cuts in the cast. Sagittal plane univalving of forearm casts is recommended.

The low-profile dorsal locking plating (DLP) technique is useful for treating dorsally comminuted intra-articular distal radius fractures; however, due to the complications associated with DLP, the technique is not widely used. A retrospective review of 24 consecutive cases treated with DLP were done. All cases were classified into two types by surgical strategy according to the fracture pattern. In type 1, there is a volar fracture line distal to the watershed line in the dorsally displaced fragment, and this type is treated by H-framed DLP. In type 2, the displaced dorsal die-punch fragment is associated with a minimally displaced styloid shearing fracture or a transverse volar fracture line. We found that the die-punch fragment was reduced by the buttress effect of small l-shaped DLP after stabilization of the styloid shearing for the volar segment by cannulated screws from radial styloid processes. At 6 months after surgery, outcomes were good or excellent based on the modified Mayo wrist scores with no serious complications except one case. The mean range of motion of each type was as follows: the palmar flexion was 50, 65 degrees, dorsiflexion was 70, 75 degrees, supination was 85, 85 degrees, and pronation was 80, 80 degrees; in type 1 and 2, respectively. DLP is a useful technique for the treatment of selected cases of dorsally displaced, comminuted intra-articular fractures of the distal radius with careful soft tissue coverage.

Randomized Controlled Trial
OBJECTIVES
To compare the results of conventional dorsal graft versus combined (dorsal plus ventral) graft urethroplasty for isolated pendulous urethral strictures a retrospective analysis of prospectively maintained data was done. Currently, the optimal treatment of pendulous urethral stricture is unknown, although buccal mucosal graft urethroplasty, with the graft placed either dorsally or ventrally, is a feasible repair option.
METHODS
Between August 2004 and January 2010, adult men suitable for 1-stage repair were randomized (alternate case) to either group 1 (dorsal only) or 2 (combined). Dorsal graft placement was done by Asopa's technique, whereas in the combined method, another strip of mucosa was placed ventrally. Parameters measured were etiology and length of stricture, operating time, complications, and outcomes.
RESULTS
Twenty men participated in the study (10 in each group). The groups were similar (P = NS) in age (mean in years, group 1: 35.3 and group 2: 38.7), etiology, and length of stricture (mean in cm, group 1: 7.2 and group 2: 7.5). The mean operating time was 102 (group 1) and 131 minutes (group 2) (P ≤.05). The complications were minor and comparable between groups. At mean follow-up of 35.7 (group 1) and 31.8 (group 2) months, 7 and 8 men had successful outcomes. The major limitation is the small number of patients and short follow-up.
CONCLUSIONS
Comparable short-term results were achieved in both groups. We suggest that if the space is inadequate dorsally, then combined graft placement is another option.
