    Abstract Adverse reaction to metal debris (ARMD) consists of a spectrum of changes ranging from pure metallosis to aseptic lymphocytic vasculitis-associated lesion and granulomatous inflammation. Currently described ARMD cases are mainly limited to arthroplasty, typically total hip and knee arthroplasties in the lower limb and total wrist arthroplasty in the upper limb. Hypersensitivity to a metallic implant in fracture fixation is rare, and a severe form of metallosis has not been reported so far. In this paper, we present a case of ARMD occurring 10 years after the use of titanium implants for fracture fixation in the hand. Intra-operative findings, histopathological results, and a literature review on ARMD are also described.

    Abstract The Mayfield sequence of progressive perilunar instability is commonly encountered. A reverse-perilunate sequence has also been described, where forces are transmitted from the ulnar wrist, resulting in progressive disruption of the ulnocarpal and lunotriquetral intervals. A concomitant dislocation of both the lunate and triquetrum together is a rare injury and has not been reproduced in cadaver models nor widely encountered in clinical cases. We report a rare case of an open volar dislocation of the lunate and triquetrum, and outline the management principles and outcomes in our patient. This case highlights that not all perilunar injuries occur in the conventional sequence. Differing paths of force transmission may result in atypical patterns of carpal disruption. Nonetheless, the broad management principles are similar. Achieving carpal reduction and stabilization, soft-tissue coverage, and early rehabilitation results in reasonable patient outcomes.

  6. Article ; Online: Scapholunate Ligament Reconstruction With a Novel Technique for Passing Split Extensor Carpi Radialis Brevis Tendon Graft Through Bone Tunnels.

    Abstract We report 2 patients with acute scapholunate dissociation with static instability and wide scapholunate gapping. They underwent scapholunate reconstruction using a split extensor carpi radialis brevis (ECRB) tendon graft via a dorsal approach. This technique is adapted from the modified Brunelli tenodesis, utilizing a portion of the ECRB instead of a flexor carpi radialis tendon graft to reconstruct the scapholunate interosseous ligaments and dorsoradiotriquetral ligaments. The novel aspects of this technique include the use of a trifold plastic sheet of biaxially oriented polypropylene to facilitate the smooth passage of the 2 mm size ECRB tendon graft through the 2 mm bone tunnel. This enables us to avoid drilling larger holes in carpal bones with a relatively poor vascular supply and allows this technique to be utilized in patients with more delicately sized scaphoid and lunate bones. A 2 mm drill bit was used to create the scaphoid and lunate tunnels, which is smaller than that in the published literature. This trifold biaxially oriented polypropylene plastic sheath can be adapted to the use of many other techniques that require passing a tendon graft through a bone tunnel.

  7. Article ; Online: The impact of various simulated arthrodesis angles of the proximal interphalangeal joint of the ring and middle finger on grip strength.

    Abstract Introduction: Arthrodesis of the proximal interphalangeal (PIP) joint at 40° angle has been proposed by many authors. A smaller angle of arthrodesis results in weaker grip strength of the hand from the quadriga effect. However, arthrodesis at 40° compromises other aspects of hand function including poor aesthetic appearance. This paper aims to quantify the decrease in grip strength at 40°, 20°, and 0° of arthrodesis.
    Materials and methods: Grip strengths of the hand were measured using a BASELINE dynamometer at settings II, III, and IV. Baseline grip strength of the subjects were first measured without wearing a splint. Thereafter, subjects wore thermoplastic splints to simulate arthrodesis of the middle and ring finger PIP joint at 40°, 20°, and 0°, and grip strengths were measured again. The grip strength of the hand with simulated arthrodesis was then calculated as a ratio of the baseline.
    Results: There were 50 subjects yielding 100 sets of results. The results show that average grip strength ratio of the hand decreases progressively from 40° and 20° and to 0° of arthrodesis for both the middle and ring finger. However, the difference in grip strength ratio between 40° and 20° of arthrodesis was minimal. Simulated arthrodesis of the middle finger affected the grip strength ratio more than arthrodesis of the ring finger, and compromised gripping of a smaller handle more than a wider one.
    Conclusion: The decrease in grip strength from 40° to 20° simulated fusion of PIP joint was minimal. Therefore, in so far as grip strength loss is concerned, arthrodesis of the PIP joint at an angle less than 40° can be considered for patients with individual functional and aesthetic concerns.

    Abstract Metacarpal osteotomies are done to correct deviation deformity in thumb duplication. We describe a suture-only technique of metacarpal osteosynthesis, without using K-wires. Thirteen Flatt Type IV thumbs and five Wassel Type VII thumbs were reconstructed with this technique. The median follow-up was 23 months. After osteotomy, the metacarpal bone fragments were sutured together with 5-0 polyglactin or 4-0 polydioxanone sutures. Metacarpal fragment displacement was not observed on postoperative radiographs obtained at 1 and 2 weeks. Bony union was achieved at 6 weeks without loss of alignment. The metacarpophalangeal joint alignment was anatomical (≤5° deviation) in eight cases. The mean pre- and postoperative metacarpophalangeal joint alignments were 27° and 9°, respectively. The 11 patients who were available for grading with the Japanese Society for Surgery of the Hand Score were assessed as good. Complete internalization of the bony fixation eliminates infections associated with exposed K-wires without compromising the overall outcome.
