3D Virtual Environment

The purpose of this study was to analyze the palmar plate complex at the proximal interphalangeal joint using a three-dimensional (3D) technique, which makes it easier to understand the dimensions of structures and their relationship to the adjacent components. This method allows individual elements to be removed virtually, facilitating clearer observation of each component. Sixteen cadaveric specimens were dissected and reconstructed in a 3D virtual environment. The palmar plate is made up of a distal, fibrous portion and a proximal, membranous portion, which anchors distally on the base of the middle phalanx and is continuous with the bilateral check-rein ligaments proximally. The accessory collateral ligaments and the A3 pulley suspend the palmar plate laterally.

Careful Physical Examination

We describe 4 cases of irreducible volar rotatory subluxation of the proximal interphalangeal (PIP) joint of the finger that required open reduction. All of the patients had radiographically proven (in lateral-view radiographs) volar rotatory subluxation of the PIP joint, without fracture. The causes of irreducibility were interposition of the lateral band about the condyle of the middle phalanx in 2 cases, interposition of the collateral ligament in 1 case, and scarring of the injured central slip in 1 case. Rupture of the collateral ligament of one side was found in all cases. Acceptable results were provided with all cases after restoration of the collateral ligaments and the damaged parts. Accurate early diagnosis by careful physical examination and obtaining true lateral radiographs of the PIP joint is important.

Level Of Evidence

The purpose of this study was to assess the lengths of the index and middle finger proximal interphalangeal joint ligaments and determine the relative changes in the collateral and accessory collateral ligament lengths at 0°, 45° and 90° flexion. We generated three-dimensional scans of 16 finger (eight index and eight middle) proximal interphalangeal joints to assess relative changes in ligament length. Significant changes were found between 45°–90° and 0°–90° for the ulnar collateral ligament of the index finger and both collateral ligaments of the middle finger between 45°–90° and 0°–90°. No significant changes in length were found for the radial collateral ligament of the index finger or the accessory collateral ligaments of the index and middle fingers. Overall, it was found that the collateral ligament length changed significantly, but there was no significant change in the accessory collateral ligaments.

Fracture Dislocations

We reviewed 20 cases of chronic dorsal fracture-dislocation of the proximal interphalangeal joint, with a mean follow-up period of 74 months. In patients without comminuted palmar fragments, open reduction and internal fixation or osteotomy of the malunited fragment provided good results. In treating patients with damaged articular cartilage or with comminuted palmar fragments by palmar plate arthroplasty, poor results were obtained because of secondary osteoarthritic changes.

Many different surgical techniques have been used to treat unstable dorsal proximal interphalangeal joint fracture-dislocations. The authors have used the base of the middle phalanx of the second toe base as an alternative autograft to treat this type of injury. This retrospective study assessed the clinical outcomes of this procedure in 11 patients. Range of motion, grip strength, Disability of the Arm, Shoulder and Hand score and donor site morbidity were assessed at regular intervals postoperatively. Nine patients had acute injuries and two had chronic injuries. The mean range of motion in the proximal interphalangeal joint at final review was 65° for patients with acute injuries and 41° for patients with chronic injuries. Other outcomes were satisfactory and there were no complications. Level of evidence: IV

3D Virtual Environment

The complexity of the urban spatial configuration, which affects human wellbeing and landscape functioning, necessitates data acquisition and three-dimensional (3D) visualisation to support effective decision-making processes. One of the main challenges in sustainability research is to conceive spatial models adapting to changes in scale and recalibrate the related indicators, depending on scale and data availability. From this perspective, the inclusion of the third dimension in the Urban Ecosystem Services (UES) identification and assessment can enhance the detail in which urban structure–function relationships can be studied. Moreover, improving the modelling and visualisation of 3D UES indicators can aid decision-makers in localising, analysing, assessing, and managing urban development strategies. The main goal of the proposed framework is concerned with evaluating, planning, and monitoring UES within a 3D virtual environment, in order to improve the visualisation of spatial relationships among services and to support site-specific planning choices.

The Difference

SummaryThis study compared the areas of cartilage accessible for curettage in arthrodesis of the equine proximal interphalangeal joint using the conventional and collateral ligament sparing approaches. For this purpose, forelimbs and hindlimbs of six equine cadavers without radiographic evidence of proximal interphalangeal joint disease were used. One limb of each pair of limbs was randomly assigned to a dissection using a standard approach to the proximal interphalangeal joint including transection of the collateral ligaments, while each contralateral limb was exposed using the same approach but leaving the collateral ligaments intact. Hohmann retractors and Spratt curettes were then used to remove as much articular cartilage as possible. Finally, proximal interphalangeal joints were photographed and image analysis was performed.Using the collateral ligament sparing procedure, the mean percentage of articular cartilage surface removed (41.2%) was significantly less than using the conventional procedure (79.6%) (p <0.01). The difference between forelimbs and hindlimbs was not significant.

Fracture Dislocations

We report a group of 14 patients with fracture dislocations of the proximal interphalangeal joint with fracture fragments of adequate size to allow reduction of the proximal interphalangeal joint and internal mini screw fixation of the bone fragment attached to the palmar plate to the base of the middle phalanx. Three years after surgery, (range 25–52 months) the average total active range of motion of the proximal interphalangeal joint was 100° (range 65–115°) for the acute group (operation within 14 days of injury, n = 7) and 86° (range 60–110°) for the chronic group (operation on average 46 days after injury, range 21–120 days, n = 7). Longer delay from injury was associated with a decreased total range of motion ( P = 0.028). Further subluxation occurred in three chronic group patients, one required further surgery. The key to successful treatment of this injury is the re-establishment of joint congruity and early mobilization. With appropriate patient selection, pain free, satisfactory range of motion can be achieved. There is a risk of persistent subluxation or dislocation, particularly if treatment is delayed.

The anatomy and histology of the volar plate at the proximal interphalangeal joint and the mechanism of fracture/subluxation of the base of the middle phalanx in closed proximal interphalangeal joint injuries is reviewed. Our current technique of repair for these injuries and its evolution from Eaton’s original procedure is described. The results of 71 cases of volar plate arthroplasty performed over a five-year period for fracture/subluxations of the proximal interphalangeal joints are presented with follow-up ranging from six months to four years. 62 (87%) patients achieved a stable pain-free joint with a range of motion from 5° to 95° within two months. Complications were uncommon and correctable with an overall eventual patient satisfaction rate of 94%.

Base Insertion

The Ascension PyroCarbon prosthesis has been used in proximal interphalangeal joint osteoarthritis. The dimensions of the intramedullary distal metadiaphyseal canal (isthmus) of the proximal phalanx and the base of the middle phalanx of cadaver fingers were investigated radiographically ( n = 304) and macroscopically ( n = 152). In up to 30% of the phalanges, the isthmus was smaller than the stem of the smallest proximal component size. The distal component head was always smaller than the middle phalanx base. Insertion and success of the Ascension PyroCarbon prosthesis is strongly dependent on bone morphology. A critical examination of the isthmus in radiographs is recommended in planning. If the isthmus is clearly smaller than the smallest proximal component, insertion of the prosthesis could be inadvisable. A clear mismatch between the distal component and the middle phalanx base should be avoided due to the potential risk for late subsidence and failure of the prosthesis.
