Distal radioulnar joint instability is commonly seen after surgical fixation of a distal radial fracture, and surgeons' ability to reliably determine stability on examination is poor. Debate remains regarding whether to fix the ulnar styloid or reinsert the triangular fibrocartilaginous complex. Four surgeons with Level 5 expertise were asked to respond to questions surrounding this debate.

We report the case of a 15-year-old boy with a de novo chromosomal deletion in the 12q13.13 region, presenting with congenital hand difference. This case emphasizes the clinical significance of recognizing such genetic anomalies and their implications.

Total wrist arthroplasty (TWA) aims to restore pain-free motion to diseased joints. One such TWA, the Motec, has demonstrated good results with acceptable complication rates. It has recently been suggested that the metal-on-carbon fibre reinforced poly ether ether ketone (Mo-CFR-PEEK) version of the Motec TWA be implanted instead of the metal-on-metal version. An explant analysis was undertaken on seven Motec Mo-CFR-PEEK TWAs, revised for a variety of reasons, after a mean time of 2 years in vivo. Compared to a new Motec implant, five of the explanted metal heads and three of the CFR-PEEK cups became smoother in vivo, suggesting self-polishing and negative skewness, indicating some material loss in vivo. Two explanted cups showed indentation marks on their rims and one of these was from component impingement with embedded metallic debris. In the short-term, the articulating surfaces of Motec Mo-CFR-PEEK TWAs did not show major damage.Level of evidence: IV.

We identified individuals born in Norway between 1970 and 2019 with transverse reduction deficiency at or above the wrist (TRDAW) from the Medical Birth Registry of Norway and from the CULA (congenital upper limb anomaly) North Oslo Registry. Infant outcomes and parental factors were compared for 202 individuals with TRDAW to 2,741,013 living individuals without TRDAW born during the same period. We found an overall TRDAW prevalence of 0.74/10,000. Infants with TRDAW had a higher risk for being small for gestational age, an Apgar score <7 and transfer to neonatal intensive care units after delivery. Nine of the infants with TRDAW had associated anomalies, most commonly in the lower limb, and at a higher proportion than the reference population. Other than twin pregnancies, we are unable to identify with certainty any other risk factors for TRDAW.Level of evidence: I.

Degenerative wrist conditions, such as scapholunate advanced collapse and scaphoid nonunion advanced collapse, often require salvage procedures to reduce pain and improve function. For early stages of disease, both proximal row carpectomy and scaphoid excision four-corner arthrodesis are viable motion-preserving options. There remains controversy on which technique is superior. Selection is a nuanced decision that requires consideration of patient characteristics and stage of disease. The traditional notion that proximal row carpectomy should be reserved for older individuals with low demands has been challenged; long-term studies in younger populations demonstrate similar patient-reported outcomes, pain relief and survivorship without conversion to total wrist arthrodesis between proximal row carpectomy and four-corner arthrodesis. The existing evidence suggests proximal row carpectomy has advantages of greater range of motion, fewer complications and lower costs. Advancements such as arthroscopic techniques for both procedures show potential, although mastery involves a steep learning curve.

There are many good reasons to improve the anatomy of a distal radius fracture, such as early return to function and avoidance of sigmoid notch incongruity or ulnocarpal impaction. It is often feared by patients, and portrayed by some authors of scientific articles and medicolegal reports, that a fracture of the distal radius has a propensity to cause symptomatic osteoarthritis. This article examines some of the current evidence and shares the authors' experience. Critical questions are asked to direct our observations and guide future research questions. We propose that both clinical experience and a literature analysis do not support the commonly held assumption that untreated distal radial fractures lead to symptomatic osteoarthritis.Level of evidence: V.

A cadaveric study showed that vascularized transfer of the articular surface of the ipsilateral first metatarsal head with the lateral collateral ligament could be suitable for reconstruction of the proximal pole of scaphoid and scapholunate ligament. Further study of the technique is recommended.

To address an inconsistency in the nomenclature of the anatomy and compressive syndromes of the deep branch of the radial nerve, we advocate for a single compression syndrome that presents along a spectrum from pain to posterior interosseous nerve palsy.
