Purpose: To assess objective and subjective outcomes of distal interphalangeal joint arthrodesis with a headless compression screw for degenerative osteoarthritis.
Methods: We retrospectively analyzed 102 cases of distal interphalangeal joint arthrodesis performed with headless compression screws on 59 patients. We included only primary cases of degenerative osteoarthritis with a minimum follow-up of 7 months. We identified appropriate bone coaptation and hardware positioning on postoperative radiographs in all digits. The mean follow-up period was 26 months (range, 7-67 mo).
Results: In 89 of 102 cases, patients were fully satisfied; in 9 cases, they were satisfied. Four complications occurred: 2 cases of prominent hardware, 1 complex regional pain syndrome type 1, and 1 symptomatic bony callus on the fused joint. Secondary surgery was required in each of these 4 cases. No nonunion, malunion, nail dystrophy, pseudarthrosis, or infection occurred. All arthrodeses healed.
Conclusions: Distal interphalangeal joint arthrodesis with headless compression screws was shown to be safe and effective in cases of degenerative osteoarthritis, with a low complication rate.

Avulsion of the Flexor Digitorum Profundus Tendon During the Curettage of a Recurrent Enchondroma: A Case Report.

Enchondroma rarely occurs in the distal phalanx, and avulsion of the flexor digitorum profundus (FDP) tendon in this area is also rare. We report a case of recurrent enchondroma in the distal phalanx, which required reconstruction for an accidental FDP avulsion during surgery. A 36-year-old right-handed woman visited our hospital with a suspected recurrence of enchondroma and a planned surgery.

Objective: Bone marrow adipose tissue (BMAT) is emerging as an important regulator of bone formation and energy metabolism. Lipolysis of BMAT releases glycerol and fatty acid substrates that are catabolized by osteoblasts. Here, we investigated whether BMAT lipolysis is involved in subchondral bone formation in hand osteoarthritis (OA).

Objectives: Volar locking plate (VLP) fixation is a very common procedure due to the high incidence of distal radius fractures (DRFs). Attritional flexor tendon rupture is a rare, but recognized complication after VLP fixation. There is no current consensus to prevent the condition.

Purpose: Terminal extensor tenotomy or Dolphin tenotomy, is a described treatment for the management of distal interphalangeal (DIP) joint hyperextension in chronic boutonniere deformity. The purpose of this study was to investigate the effects of incremental partial Dolphin tenotomy in correcting boutonniere deformity, with a focus on evaluating the improvement in DIP joint hyperextension deformity and documenting the development of iatrogenic mallet finger.
Methods: Thirty-eight fingers from 10 cadaveric hands were used.

Introduction: Psoriatic arthritis (PsA) is a heterogeneous disease with various manifestations such as dactylitis, enthesitis, spondylitis, and skin involvement. Minimal disease activity (MDA) has been successfully used in daily clinical practice and is considered a reasonable treatment target in patients with PsA. In this study, we aimed to evaluate the MDA status and associated factors in patients with PsA in our tertiary referral clinic.
