This study aims to report the outcomes in the treatment of unstable proximal third scaphoid nonunions with arthroscopic curettage, non-vascularized bone grafting, and percutaneous fixation. This was a retrospective analysis of 20 patients. All cases were delayed presentations (n = 15) or failed nonoperatively managed scaphoid fractures (n = 5). Surgery was performed at a mean duration of 27 months (7 to 120) following injury with arthroscopic debridement and arthroscopic iliac crest autograft. Fracture fixation was performed percutaneously with Kirschner (K)-wires in 12 wrists, a headless screw in six, and a combination of a headless screw and single K-wire in two. Clinical outcomes were assessed using grip strength, patient-reported outcome measures, and wrist range of motion (ROM) measurements.Aims
Methods
Aims. Fixation of scaphoid nonunion with a volar locking plate and cancellous bone grafting has been shown to be a successful technique in small series. Few mid- or long-term follow-up studies have been reported. The aim of this study was to report the mid-term radiological and functional outcome of plate fixation for scaphoid nonunion. Methods. Patients with a scaphoid nonunion were prospectively enrolled and treated with open reduction using a volar approach, debridement of the nonunion, and fixation using a locking plate and cancellous bone grafting, from the ipsilateral iliac crest. Follow-up included examination, functional assessment using the patient-rated wrist/hand evaluation (PRWHE), and multiplanar reformation CT scans at three-month intervals until union was confirmed. Results. A total of 49 patients with a mean age of 31 years (16 to 74) and a mean duration of nonunion of 3.6 years (0.4 to 16) were included. Postoperatively, the nonunion healed in 47 patients (96%) as shown on CT scans. The mean time to union was 4.2 months (3 to 12). Due to impingement of the plate on the volar rim of the radius and functional limitation, the hardware was removed in 18 patients. At a median follow-up of 38 months in 34 patients, the mean active range of motion (ROM) improved significantly from 89° to 124° (SD 44°; p = 0.003). The mean grip strength improved significantly from 52% to 79% (SD 28%; p < 0.001) of the contralateral side. The mean PRWHE score improved significantly from 66 to 17 points (SD 25; p < 0.001). Conclusion. Locking plate fixation supplemented with
Arthritis of the wrist is a painful disabling
condition that has various causes and presentations. The traditional treatment
has been a total wrist fusion at a price of the elimination of movement.
However, forms of treatment which allow the preservation of movement
are now preferred. Modern arthroplasties of the wrist are still
not sufficiently robust to meet the demands of many patients, nor
do they restore normal kinematics of the wrist. A preferable compromise
may be selective excision and partial fusion of the wrist using
knowledge of the aetiology and pattern of degenerative change to
identify which joints can be sacrificed and which can be preserved. This article provides an overview of the treatment options available
for patients with arthritis of the wrist and an algorithm for selecting
an appropriate surgical strategy. Cite this article:
Damage to the cartilage of the distal radioulnar
joint frequently leads to pain and limitation of movement, therefore repair
of this joint cartilage would be highly desirable. The purpose of
this study was to investigate the fixation of scaffold in cartilage
defects of this joint as part of matrix-assisted regenerative autologous
cartilage techniques. Two techniques of fixation of collagen scaffolds,
one involving fibrin glue alone and one with fibrin glue and sutures, were
compared in artificially created cartilage defects of the distal
radioulnar joint in a human cadaver. After being subjected to continuous
passive rotation, the methods of fixation were evaluated for cover
of the defect and pull out force. No statistically significant differences were found between the
two techniques for either cover of the defect or integrity of the
scaffold. However, a significantly increased mean pull out force
was found for the combined procedure, 0.665 N (0.150 to 1.160) This suggests that although successful fixation of a collagen
type I/III scaffold in a distal radioulnar joint cartilage defect
is feasible with both forms of fixation, fixation with glue and
sutures is preferable. Cite this article:
