Dispelling the Myth of Work-Related de Quervain's Tenosynovitis

De Quervain's tenosynovitis: a non-randomized two-armed study comparing ultrasound-guided steroid injection with surgical release

PURPOSE

Ultrasonography is currently used for both diagnostic and therapeutic purposes in de Quervain's tenosynovitis. There is a dearth of information on how effective an ultrasound-guided (USG) steroid injection is when compared to surgical release of the first extensor compartment. Hence, we performed a non-randomized two-armed comparison study to test our hypothesis that USG guided steroid injection is equally effective as surgery.

METHOD

62 consecutive patients participated in the study with 32 of them selecting the option of USG guided injection (Set A), and the rest undergoing surgical release (Set B). We reviewed them after 3 and 6 weeks and 6 months for functional outcome using DASH, PRWE and VAS scores, recurrence, or any complications. They were further followed if they were symptomatic.

RESULTS

The DASH/PRWE/VAS scores improved at the end of 6 months from 81.7/79.3/6.8 to 1.0/1.7/1.0, respectively for patients undergoing USG guided steroid injection. Similarly, for the patient undergoing surgery, the scores improved from 82.2/81.5/6.7 to 1.7/3.4/1.0, respectively. This was statistically significant in both the groups (p < 0.05) and was comparable to each other. Two patients in Set A came back with recurrence at eight and 10 months and two reported occasional pain on heavy work. Three patients had tenderness and two had numbness in Set B at the scar site.

CONCLUSION

We observed that USG guided steroid injections are comparable to surgical release in terms of pain relief, functional outcome, complications.

Work-Related De Quervain's Tensosynovitis (DQT): The Diagnosis Dilemma

A female presented with right wrist pain for nine months. The diagnosis was De Quervain's tenosynovitis; her condition was initially managed conservatively, but later she needed surgery due to the lack of improvement. No workplace intervention had been implemented because her hand surgeons did not consider her occupational exposures. It was later discovered that there was significant exposure to ergonomic hazards at her workplace. She received accommodations in her workplace that led to reduction of exposure to ergonomic hazards and the subsequent dramatic improvement in her condition. This case report indicates that some orthopedists do not appreciate the role of occupational exposure to ergonomic hazards in the pathogenesis of similar conditions. Occupational medicine specialists and orthopedists should, therefore, communicate with each other to reach a consensus regarding the association between occupational exposures to ergonomic hazards and work-related upper limb disorders (WRULDs).
