Situation

Displaced patellar fractures disrupt the knee extensor apparatus and articulate incongruously with the femoral trochlea, mandating anatomical reduction and stable internal fixation. For decades, modified Kirschner wire tension-band wiring (TBW) has served as the conventional standard of care. However, TBW is associated with high reoperation rates due to hardware prominence, wire back-out, and soft-tissue irritation. This multicentre trial investigates whether low-profile locking plate fixation delivers superior functional knee recovery and fewer secondary operations.

Background

While TBW converts anterior tensile forces into dynamic interfragmentary compression during knee flexion, its biomechanical stability is vulnerable to multi-fragmentary comminution, osteopenia, and cyclical quadriceps contraction. Anatomically contoured anterior locking plates offer fixed-angle multiplanar screw purchase, superior resistance to gapping, and eliminated wire migration. However, whether these biomechanical advantages translate into patient-reported outcome superiority in a blinded randomized setting had not been established.

Assessment & Findings
  • Design & Cohort: Patient- and assessor-blinded, multicentre randomized controlled trial conducted across 5 trauma centres. A total of 122 adults with acute displaced patellar fractures requiring open reduction and internal fixation were randomized 1:1 to locking plate fixation (n = 63) or modified tension-band wiring (n = 59). At 12-month follow-up, 90.5% (57/63) of locking plate and 88.1% (52/59) of TBW patients completed full evaluations. The primary outcome was patient-reported knee function measured across the 5 Knee Injury and Osteoarthritis Outcome Score (KOOS) subscales, with superiority defined a priori as significant differences exceeding the minimal clinically important difference (MCID) in >=3 subscales.
  • Primary Findings: Locking plate fixation demonstrated clear superiority over tension-band wiring, achieving statistically significant and clinically meaningful improvements exceeding the MCID across 3 KOOS subscales at 12 months: Symptoms (mean difference [MD]: -10.4, 95% CI: -16.4 to -4.4), Sport and Recreation (MD: -14.1, 95% CI: -24.7 to -3.4), and Knee-Related Quality of Life (MD: -10.9, 95% CI: -19.0 to -2.7).
  • Complications & Reoperations: Secondary endpoints showed that symptomatic hardware prominence, fixation failure, and secondary reoperations for hardware removal occurred substantially more frequently after tension-band wiring compared to locking plate fixation. No differences were noted in deep surgical site infection rates.
Recommendation & Practice Takeaway

Clinical Pearl: Anatomically contoured locking plate fixation represents a decisive advance over traditional tension-band wiring for displaced patellar fractures, delivering superior 12-month functional recovery across symptoms, athletic function, and quality of life while reducing hardware-related reoperations. Orthopaedic trauma surgeons should adopt low-profile anterior locking plates as their preferred construct for displaced patellar fractures, especially in comminuted patterns or active patients desiring early aggressive knee mobilization.

Upper Extremity Trauma & Scaphoid

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

Authors: Zhang W, Yi C, Wu P, Hu G, Shen Y et al. | Journal: The Journal of the American Academy of Orthopaedic Surgeons (JAAOS) (Aug 2026) | View Source / DOI

Situation

The landmark UK SWIFFT randomized trial concluded that surgical fixation provides no meaningful functional advantage over cast immobilization for minimally displaced scaphoid waist fractures, advocating conservative treatment as the cost-effective initial standard. However, whether SWIFFT findings translate universally across diverse populations with different smoking rates, occupational physical demands, and fracture displacement thresholds has remained intensely debated. This target trial emulation of 6,769 patients re-evaluates the surgical versus conservative dilemma.

Background

Scaphoid waist fractures carry a notorious risk of nonunion due to retrograde endosteal vascular supply. While conservative cast immobilization avoids surgical morbidity, nonunion rates range from 10% to 20%, resulting in carpal instability and scaphoid nonunion advanced collapse (SNAC wrist). Headless compression screws provide rigid internal stability and earlier functional use, but risk screw protrusion, tendon irritation, and iatrogenic cartilage damage. Identifying specific clinical subgroups that derive clear net benefit from upfront surgery is vital.

Assessment & Findings
  • Design & Cohort: Target trial emulation utilizing a clone-censor-weight design with inverse probability of treatment and censoring weighting (IPTW) across three tertiary university hospitals (2018-2024). Eligible patients were adults aged >=16 years presenting within 14 days with bicortical scaphoid waist fractures (displacement <=2 mm). The cohort comprised 6,769 patients (mean age 32.1 years; 81.6% male; 42.4% active smokers) who received either headless compression screw fixation (n = 2,544) or below-elbow cast immobilization (n = 4,225). Primary outcome was DASH score at 52 weeks.
  • Primary Outcomes & Nonunion: Surgical fixation produced statistically significant DASH improvements at 52 weeks (adjusted mean difference [MD]: -4.2, 95% CI: -4.9 to -3.5, p < 0.001), though the overall effect remained below standard MCID thresholds (10-15 points). Crucially, surgery cut the nonunion risk in half (8.4% vs 17.5%; risk ratio [RR]: 0.48, 95% CI: 0.41 to 0.55). Nearly 1 in 5 cast-treated patients (18.1%) ultimately failed nonoperative management and required secondary surgery for nonunion.
  • Complications & Subgroup Heterogeneity: Upfront surgery increased overall complications sevenfold (14.1% vs 2.0%), predominantly screw-related prominence, superficial infection, and scar tenderness. However, substantial subgroup heterogeneity emerged: surgical benefits were dramatically higher in active smokers (DASH improvement: -6.7) and patients with initial displacement of 1-2 mm (DASH improvement: -8.5).
Recommendation & Practice Takeaway

Clinical Pearl: While below-elbow cast immobilization remains a sound first-line option for strictly undisplaced scaphoid fractures in non-smokers, upfront percutaneous headless compression screw fixation should be strongly favored for active smokers and fractures with 1 to 2 mm displacement. In these vulnerable subgroups, surgical fixation provides clinically meaningful functional gains and cuts nonunion risk in half, sparing patients from the 18% nonunion conversion rate associated with prolonged cast immobilization.

Periprosthetic Fractures & Femur

3. A Dual-Implant Approach to Vancouver C Femur Fractures: Improved Outcomes With Retrograde Nail and Lateral Plate Fixation Compared With Lateral Locked Plating

Authors: Page B, Shaath M, Rechter G, Nasir B, Baker T et al. | Journal: Journal of Orthopaedic Trauma (JOT) (Oct 2026) | View Source / DOI

Situation

Vancouver C periprosthetic femur fractures occur well distal to a stable femoral stem, presenting a difficult reconstructive dilemma in frail, osteoporotic geriatric patients. The historical standard of isolated lateral locked plating (LLP) requires 6 to 8 weeks of restricted weight-bearing, precipitating rapid physiological deconditioning and nonunion rates exceeding 10% to 15%. This comparative study assesses whether a dual-implant construct combining a retrograde intramedullary nail with a lateral locked plate eliminates nonunion and permits safe immediate full weight-bearing.

Background

The bone segment between the distal tip of a rigid hip prosthesis and the distal femoral condyles represents an extreme mechanical stress-riser. Single lateral locked plates acting as unilateral cantilever beams are prone to cyclic fatigue, varus collapse, and nonunion when subjected to early weight-bearing forces. Integrating an intramedullary load-sharing nail inside the medullary canal with an extramedullary lateral locking plate creates an orthogonal load-sharing composite with superior rotational and axial rigidity.

Assessment & Findings
  • Design & Cohort: Comparative cohort study at an academic Level-1 trauma centre evaluating 52 consecutive adult patients undergoing surgical stabilization for Vancouver C periprosthetic femur fractures (AO/OTA 32C). Patients were treated with either a dual-implant retrograde intramedullary nail combined with a minimally invasive lateral locked periprosthetic plate (NP group, n = 31; 68% female, mean age 79 years) or isolated lateral locked plating (LLP group, n = 21; 67% female, mean age 69 years). NP patients were permitted immediate full weight-bearing, while LLP patients were restricted to non-weight-bearing for 8 weeks. All patients were followed to union or minimum 1 year.
  • Union Rates & Reoperation: The dual-implant NP construct achieved a 100% union rate (0/31 nonunions, 0%), whereas isolated LLP resulted in 3 nonunions out of 21 patients (14.3%, p = 0.03). All 3 nonunions in the LLP group required revision to dual nail-plate constructs, which subsequently healed. Reoperation rates did not differ significantly overall (6% in NP vs 14% in LLP, p = 0.68), with NP reoperations limited to simple removal of a prominent distal interlocking screw.
  • Coronal Alignment & Safety: Both cohorts maintained anatomical distal femoral coronal alignment through final follow-up (NP mean aLDFA 82 deg postoperatively to 80 deg at union, p = 0.37; LLP 80 deg to 82 deg, p = 0.43). There were zero cases of catastrophic hardware breakage, mechanical pullout, or deep surgical site infection in either cohort.
Recommendation & Practice Takeaway

Clinical Pearl: Dual-implant fixation combining a retrograde intramedullary nail with a lateral locked periprosthetic plate significantly outperforms single-plate fixation for Vancouver C femur fractures, achieving a 100% union rate (vs 14% nonunion with isolated plating) while safely unlocking immediate full weight-bearing. For elderly patients with periprosthetic fractures, immediate mobility is life-saving: orthopaedic trauma surgeons should embrace dual nail-plate constructs to avert prolonged recumbency, delirium, and revision surgery.
