1. Surgical Fixation Versus Cast Immobilization for Adults With Bicortical Scaphoid Fractures: A Target Trial Emulation of the SWIFFT Trial.

Situation

The landmark SWIFFT randomized trial reported no clinically meaningful functional difference between surgical fixation and cast immobilization for minimally displaced scaphoid waist fractures in the UK National Health Service. This large-scale target trial emulation evaluated whether these findings translate across diverse clinical populations and identified high-risk subgroups that derive substantial benefit from primary surgery.

Background

Scaphoid waist fractures carry high risks of avascular necrosis and nonunion. While casting avoids surgical trauma, cast immobilization causes prolonged joint stiffness, muscle atrophy, and delayed union. Conversely, percutaneous compression screws expedite rehabilitation but risk hardware prominence and reoperation.

Assessment & Findings
  • Study Design & Cohort: Target trial emulation utilizing a clone-censor-weight design with inverse probability weighting across 6,769 adults (mean age 32.1 years; 81.6% male; 42.4% smokers) with acute bicortical scaphoid waist fractures (displacement 2 mm or less) treated with headless compression screw fixation (n = 2,544) or below-elbow cast immobilization (n = 4,225).
  • Functional Outcomes: Primary surgical fixation yielded statistically significant improvements in DASH scores at 52 weeks (adjusted mean difference: -4.2 points, 95% CI, -4.9 to -3.5; P < 0.001), approaching lower MCID thresholds.
  • Nonunion & Revision Burden: Surgery halved the risk of nonunion compared to casting (8.4% vs 17.5%; RR = 0.48, 95% CI, 0.41 to 0.55). Nearly one in five cast-treated patients (18.1%) ultimately required secondary surgery for nonunion.
  • Complication Trade-Offs: Surgical fixation increased minor complication risks sevenfold (14.1% vs 2.0%), predominantly driven by screw protrusion, hardware irritation, and reoperation for hardware removal.
  • High-Benefit Subgroups: Subgroup analyses revealed substantially greater surgical advantages among patients with displaced fractures (-8.5 DASH points) and active smokers (-6.7 DASH points).
Recommendation & Practice Takeaway

Clinical Pearl: Cast immobilization remains an acceptable first-line treatment for truly undisplaced scaphoid fractures in non-smokers willing to accept close radiographic surveillance. However, in active smokers or fractures displaying subtle cortical displacement (1 to 2 mm), primary percutaneous headless compression screw fixation halves nonunion rates (8.4% vs 17.5%) and averts the nearly 18% delayed surgery rescue rate observed with cast treatment.

2. The Likelihood of Future Dupuytren Disease Intervention After Initial Treatment in the Same Digit, Another Digit, and Contralateral Hand.

Authors: El Bachaoui R, Cossu E, Zhang D, Earp B, Blazar P | Journal: The Journal of Hand Surgery (Oct 2026) | View Source / DOI

Situation

Dupuytren disease is a progressive fibroproliferative disorder of the palmar fascia. While treatment restores digital extension, disease recurrence and progression to other digits or the contralateral extremity are common. This longitudinal study quantified multi-site re-intervention risks following surgical fasciectomy versus collagenase clostridium histolyticum (CCH) injections.

Background

Patients undergoing treatment for single-digit Dupuytren contracture frequently assume that intervention provides permanent resolution. Quantifying specific risks of secondary procedures on the index finger, adjacent digits, and the contralateral hand is essential for realistic preoperative counseling.

Assessment & Findings
  • Study Design & Cohort: Longitudinal cohort of 341 patients (141 initially treated with open fasciectomy, 200 with CCH injections) followed for a mean of 5.3 years to track subsequent interventions across three anatomical zones.
  • Overall Re-intervention Rate: Within 5.3 years of initial treatment, 42% of patients (142 of 341) required at least one subsequent intervention for Dupuytren contracture.
  • Anatomical Distribution & Timing: Revision procedures on the same digit occurred in 26% of patients (n = 88) at a mean of 3.2 years; intervention on another digit in the same hand occurred in 10% (n = 35) at a mean of 3.6 years; and surgery on the contralateral hand occurred in 23% (n = 79) at a mean of 2.3 years.
  • Independent Predictors of Recurrence: Initial treatment with collagenase (vs fasciectomy), multiple digits involved at baseline, and untreated concomitant cords predicted same-digit revisions. Younger age, active tobacco smoking, and baseline untreated cords were significant independent predictors of new contractures in other digits of the same hand. Dominant-hand involvement predicted contralateral disease progression.
Recommendation & Practice Takeaway

Clinical Pearl: Surgeons should counsel patients upfront that Dupuytren disease is a systemic condition: over 40% of patients require additional interventions within 5 years (26% on the index finger, 10% on another finger, and 23% on the opposite hand). Young patients, active smokers, and individuals presenting with multi-digit involvement should be educated on aggressive diathesis and monitored closely for contralateral progression.

3. No Difference in Outcome Comparing Autograft and Allograft in Arthroscopic-Assisted Bone Grafting for Treating Unstable Scaphoid Nonunion.

Authors: Chang C, Wu C, Wang J, Huang Y, Yin C et al. | Journal: Arthroscopy: The Journal of Arthroscopic and Related Surgery (Oct 2026) | View Source / DOI

Situation

Unstable scaphoid nonunion with humpback deformity leads to progressive carpal collapse and scaphoid nonunion advanced collapse (SNAC) wrist. Arthroscopic-assisted bone grafting (ABG) with internal screw fixation allows direct visualization of articular alignment and preservation of extrinsic carpal ligaments. This study compared structural union and functional recovery between cancellous autograft and allograft.

Background

Iliac crest or distal radius autografts have long been considered the osteogenic gold standard, but harvest procedures cause donor-site morbidity, sensory nerve injury, and prolonged operative time. Whether cancellous allograft provides comparable osteoinductive healing in an arthroscopically prepared nonunion bed has remained controversial.

Assessment & Findings
  • Study Design & Cohort: Comparative cohort study of 74 patients with unstable scaphoid nonunions treated with arthroscopic-assisted debridement, bone grafting, and compression screw fixation using either autograft (n = 47) or allograft (n = 27) with a minimum follow-up of 12 months (mean: 20.4 vs 18.7 months).
  • Union Rates & Consolidation Time: Bony union was achieved in 93.6% of the autograft group (3 persistent nonunions, 6.4%) and 88.9% of the allograft group (3 persistent nonunions, 11.1%), demonstrating no statistically significant difference (P = 0.667). Mean time to union was 3.4 plus/minus 0.7 months for autograft versus 3.7 plus/minus 1.1 months for allograft (P = 0.266).
  • Carpal Alignment & Height Restoration: Both groups achieved significant restoration of scaphoid length. The allograft group achieved superior post-reduction scapholunate angles and comparable radiolunate angle correction compared to the autograft cohort.
  • PROMs & Clinical MCID: Visual analog scale pain scores dropped from 3.9/4.3 to 0.4/0.5, QuickDASH improved from 28.9/29.0 to 8.4/9.1, and modified Mayo Wrist Scores improved from 68.9/70.2 to 89.3/87.9 (all P < 0.001). MCID was achieved by 93.6% of autograft and 96.3% to 100% of allograft patients.
Recommendation & Practice Takeaway

Clinical Pearl: Cancellous allograft combined with arthroscopic preparation achieves union rates (89% vs 94%) and functional scores comparable to autograft while eliminating donor-site pain and morbidity. The critical technical surgical requirement is meticulous arthroscopic curettage and burr debridement back to healthy, bleeding punctate bone ('paprika sign') prior to allograft impaction and central headless screw fixation.
