Key Takeaway
Note that untreated ulnar styloid fractures do not significantly impact long-term wrist function or grip strength.

This meta-analysis analyzed data from 1383 patients to compare patient-reported wrist joint function scores between isolated distal radius fractures (DRF) and DRF combined with untreated ulnar styloid fractures (USF). The study aimed to determine if the presence of a concurrent USF impacts functional recovery.

Short-term results (under 6 months) showed that patients with both DRF and USF had statistically inferior wrist function scores compared to those with isolated DRF. However, the effect size was small (SMD = 0.20; 95% CI: 0.05-0.34, P = 0.01), and the authors noted that clinical significance for this finding was limited. In the medium- to long-term period (6 months or more), no significant statistical difference was found between the two groups (SMD = 0.11; 95% CI: -0.02-0.24, P = 0.11).

Secondary outcomes including grip strength and wrist joint range of motion showed no significant differences between patients with or without concurrent USF after surgery. Additionally, no significant difference was found in prognosis between base fractures and tip fractures at 3 and 12 months postoperatively. The authors suggest that a non-intervention approach for USF in clinical practice may not lead to a poor long-term prognosis.

How this fits prior evidence

This meta-analysis addresses the impact of ulnar styloid involvement on functional outcomes. It builds upon prior evidence regarding distal radius fracture management, such as the identification of ulnar variance as a predictor for loss of reduction and the comparison of various surgical techniques like percutaneous pinning.

If you have broken your wrist, you might worry about how a nearby small bone called the ulnar styloid affects your recovery. Some people worry that an extra fracture in this area makes it harder to move or grip objects after surgery.

Researchers looked at data from 1,383 patients to see if having both a distal radius fracture and an ulnar styloid fracture changed things. They found that while patients with both fractures reported slightly lower wrist function scores in the first six months, the difference was small. By the six-month mark, there was no significant difference in function between the two groups.

Other measures, like grip strength and the range of motion for moving the wrist, showed no differences at all. This suggests that not treating the ulnar styloid fracture might not lead to a worse long-term outlook for patients with a broken wrist.

What this means for you:
Wrist function scores may be slightly lower in the first six months but stabilize over time regardless of styloid damage.

Common questions

Does an ulnar styloid fracture make it harder to move my wrist?

The study found no significant difference in the range of motion for moving the wrist, including flexion and extension, between patients with and without ulnar styloid fractures after surgery.

Will my grip strength be weaker if I have both fractures?

No. The data showed no significant difference in grip strength between patients who had only a distal radius fracture and those who also had an ulnar styloid fracture.

How does the recovery change over time for these injuries?

Patients with both fractures reported slightly lower function scores in the first six months, but this difference was small. After six months, there was no significant difference in wrist function between the two groups.

BACKGROUND: Ulnar styloid fractures (USF) often occur in conjunction with distal radius fractures (DRF). This study aims to compare wrist prognosis between DRF patients with untreated USF and those with isolated DRF, and to assess the impact of different USF fracture types. METHODS: A systematic search was conducted in databases such as PubMed, Embase, and the Cochrane Library, up to January 17, 2026. Randomized controlled trials (RCTs) and cohort studies comparing the wrist joint prognosis of patients with DRF combined with USF and those with isolated DRF were included. The primary outcome measure was the patient-reported wrist joint function score, and the secondary outcome measures were grip strength and wrist joint range of motion (ROM). RESULT: 11 studies involving 1383 patients were included. In the short-term (≤6 months) follow-up, the wrist function score of patients with DRF combined with USF was statistically inferior to that of patients with DRF alone (SMD = 0.20, 95% CI: 0.05-0.34, P = 0.01), but the effect size was small and the clinical significance was limited. In the medium- to long-term (≥6 months) follow-up, there was no significant statistical difference in wrist function scores between the two groups (SMD = 0.11, 95% CI: -0.02-0.24, P = 0.11). Further analysis indicated that there was no significant statistical difference in prognosis between patients with base fractures and those with tip fractures at 3 and 12 months postoperatively. Additionally, there was no significant statistical difference in grip strength and wrist joint range of motion (including flexion, extension, pronation, supination, ulnar deviation, and radial deviation) between the two groups after surgery. CONCLUSION: Untreated USF do not compromise wrist function in patients with DRF, regardless of the USF fracture type. Based on the existing evidence, non-intervention for USF in clinical practice may not lead to poor prognosis. REGISTRATION: CRD420261286648.
