Salvage of the Unstable Sauve´-Kapandji Procedure: A New Technique

The Sauvé-Kapandji procedure has been commonly performed in the setting of posttraumatic osteoarthritis of the distal radioulnar joint. A recognized complication is instability of the proximal ulnar stump, which may occur in up to 33% of cases. Salvage of the failed Sauvé-Kapandji procedure in this setting is difficult and can sometimes involve sacrifice of forearm rotation. We report the results of 3 cases of a new salvage procedure in this setting. The radioulnar pseudarthrosis was taken down; ulnar continuity was restored with an intercalary graft; and forearm rotation was restored with matched hemiresection and interposition arthroplasty at the site of previous radioulnar fusion. Postoperatively, all patients achieved good forearm rotation (mean supination, 60 degrees; mean pronation, 65 degrees), had no symptoms of instability, and were satisfied with the results of the procedure. Disabilities of the Arm, Shoulder and Hand scores improved from preoperative mean of 55 to postoperative mean of 18.

Early experience with the trimed fragment-specific fracture fixation system in intraarticular distal radius fractures

This paper reports the results of fixation of intraarticular fractures of the distal radius using the TriMed fragment-specific fixation system by surgeons early in their experience with the system. A consecutive series of 22 AO types C2 and C3 fractures in 21 patients were internally fixed with the system. Restoration of articular congruity to less than 2 mm was possible in 20 fractures. At a minimum of 6 months follow-up, mean volar and radial inclination were 8° and 25°, respectively, with no loss of reduction. The patients had a mean of 50° flexion, 63° extension and a pronation–supination arc of 149°. The mean subjective Patient Rated Wrist Score was 20. Our complication rate was comparable to other published series despite long operating times. Therefore, we commend the system as a powerful tool to treat these difficult fractures but acknowledge the significant learning curve.

Correction of Residual Radial Translation of the Distal Fragment in Distal Radius Fracture Open Reduction

Distal radius fractures are common injuries of the upper extremity requiring treatment. In recent years, volar locking plate (VLP) fixation has become favored for operative treatment with the main goals being anatomic reduction and rigid fixation allowing for an early range of motion rehabilitation protocol. VLP fixation is excellent at correcting sagittal plane alignment with restoration of volar tilt. However, plate designs do not have any intrinsic features to their designs to assist with correction of coronal plane translation. One possible sequela of distal radius fractures is residual instability of the distal radioulnar joint. This instability can lead to pain and disability after treatment of distal radius fractures requiring further interventions. It has been demonstrated that coronal plane malreduction with residual radial translation of the distal fragment may contribute to ongoing distal radioulnar joint instability after distal radius fractures. We describe a technique for intraoperative correction of residual radial translation. It may be used when radial translation is recognized during internal fixation with a VLP or when correction of radial translation is required as part of a corrective osteotomy for radial malunion.

Measuring thumb range of motion in first carpometacarpal joint arthritis: The inter-rater reliability of the Kapandji Index versus goniometry

Introduction Goniometric measurement of thumb range of motion is often used as an outcome measure in assessing patients with first carpometacarpal osteoarthritis. Despite common use and demonstrated construct validity, the reliability of this technique has not been well established. The Kapandji Index is an alternate functional measure of thumb motion suitable for use with this client group. The purpose of this study was to examine the inter-rater reliability of the goniometric measures for thumb joint range of motion compared to the Kapandji Index in patients with first carpometacarpal joint osteoarthritis. Methods Two independent assessors, who were blind to each other’s measurements, measured thumb range of motion in 33 patients (54 thumbs). All participants were undergoing treatment for carpometacarpal joint osteoarthritis. Active range of motion was measured with a goniometer for all the thumb joints using a standardised measurement protocol. The Kapandji Index score was recorded. Relative reliability was assessed by using the intraclass correlation coefficient. Absolute reliability was also calculated by determining the standard error of measurement (SEM68) and the minimal detectable difference (MDD90). Results Inter-rater reliability for the goniometer was highly variable ranging from poor to excellent (intraclass correlation coefficient 0.128–0.860). The SEM68 ranged from 9° to 13°, and the resulting MDD90 varied from 21° to 31° for the different thumb joints. The Kapandji Index had excellent inter-rater reliability among the different raters (intraclass correlation coefficient 0.772–0.917). Conclusions Measurement of goniometric active range of motion of the thumb may have limited utility as a measure of clinical effectiveness for patients with carpometacarpal joint osteoarthritis. However, the Kapandji Index is a reliable measure of functional range of motion.

The effectiveness of the Push Brace™ orthosis and corticosteroid injection for managing first carpometacarpal joint osteoarthritis: A factorial randomised controlled trial protocol

Introduction Various conservative treatments for first carpometacarpal joint osteoarthritis have been reported. We aim to investigate the short-term effectiveness of conservative management interventions used to improve pain and function for adults with first carpometacarpal joint arthritis in a randomised controlled trial. Methods A pragmatic 2 × 2 factorial randomised controlled trial will be conducted. This randomised controlled trial will have one control group (hand therapy) and three intervention groups. Interventions will include Push Brace™ orthosis and hand therapy, ultrasound-guided intra-articular corticosteroid injection and hand therapy and a combination of all three interventions. A total of 276 participants will be recruited for the trial. The primary outcomes will be pain (reported using a Visual Analogue Scale) and function (using the Patient Rated Wrist/Hand Evaluation). Secondary outcomes will include osteoarthritis specific function, pinch strength, global change and quality of life. Adverse events and complications will be reported. Outcomes assessments will be completed prior to the intervention and at 3, 6, 12 and 24 months post-intervention. The trial will be conducted at a private hand surgery clinic in Queensland, Australia. Conclusions Results from this trial will contribute to the evidence on conservative management of first carpometacarpal osteoarthritis.

Use of Low-profile Palmar Internal Fixation in Digital Replantation.

There are multiple surgical techniques to stabilize the bone in digital replantation. Various criteria need to be considered when choosing appropriate bony fixation including operative time, ease of exposure, stability, limitation of the area of dissection, and reproducibility. We describe our technique using internal fixation with a low-profile plate on the palmar aspect of the proximal or middle phalanx during replantation of a digit. This technique allows coverage of the plate with no risk of compromising the dorsal venous anastomosis. In our experience, using this technique we have observed no complications including no secondary displacement of the fragments or extensor tendon rupture and no incidence of infection. In addition, this technique allows adequate bony fixation to enable an early active range of motion rehabilitation program.

Management of Scapholunate Ligament Pathology

The challenges presented by pathology of the Scapholunate Ligament (SLL) complex require a thorough understanding of the anatomy and pathomechanics of the relevant structures. The history will not always yield the stereotypical acute high-energy traumatic insult to the wrist and cumulative injury needs to be considered.
