Effect of flexor tendon tenotomy of the diabetic hammertoe on plantar pressure: a randomized controlled trial
Authors' conclusion
This study found that tenotomies of the diabetic hammertoe reduces plantar pressure affecting the treated toes. This likely explains the positive effects of tenotomy treatment on diabetic foot ulcers.
Study context
- Population
- Participants with diabetic hammertoe deformity; mean age 65.6 (SD 9.5) years, 57.8% male, 66.7% T2D95 screened
- Participants
- 45 participants
- Comparison
- Tenotomy plus standard non-surgical treatment vs standard non-surgical treatment alone
- Tenotomyn = 22
- Primary endpoint
- Change in peak plantar pressure (barefoot) post tenotomy treatment
- Follow-up
- 3 months post-intervention

Primary result
As reported in the abstract
Change in peak plantar pressure (PPP) of toe regions
Tenotomy
−145.3
average · range as printed −225.9–-56.2 · kPa
Control
−1.6
average · range as printed −30.2–27.9 · kPa
P = 0.00017
Further findings
Peak plantar pressure (PPP) in toe regions, Tenotomy, pre- to post-intervention · pre-intervention to 3 months post-intervention
- Pre-intervention PPP, Tenotomy (Q1–Q3 152.0-289.1)
- 205.6 kPa
- Post-intervention PPP, Tenotomy (39.1-100.5)
- 61.3 kPa
- Within-group reduction
- P < 0.0001
