Management of Stenosing Flexor Tenosynovitis: Maximizing Nonoperative Success without Increasing Morbidity.

BACKGROUND: Traditional nonoperative management of stenosing tenosynovitis is limited to one corticosteroid injection, followed by surgery in the case of failure. Recently, nonoperative strategies have been extended to include two or three injections despite the absence of large prospective studies supporting this practice. METHODS: A prospective study was performed of all patients presenting with stenosing tenosynovitis to a single surgeon (R.S.R.) over a 22-year period. Patients with potentially confounding comorbidities were excluded. All digits received one to three injections of triamcinolone acetonide plus local anesthetic into the tendon sheath. Data were analyzed by digit. RESULTS: Five hundred seventy-one digits (401 patients) were included. Digits that were symptomatic for 3 months or less were more likely to resolve after one injection than those that were symptomatic for more than 3 months (OR, 2.6; 95 percent CI, 1.67 to 4.0; p < 0.01). For the digits that failed to resolve after the first injection, those that were symptomatic for 5 months or less before one injection were more likely to respond to a second injection than those that were symptomatic for more than 5 months (OR, 9.4; 95 percent CI, 3.0 to 29.7; p < 0.01). Eight digits received three injections, after which six (75 percent) achieved remission. There were no instances of tendon/pulley rupture, infection, or soft-tissue atrophy. CONCLUSIONS: Stenosing tenosynovitis is more likely to respond to nonoperative therapy when treated before 3 months. It is safe and effective to administer more than one corticosteroid injection, as second and third doses increase the overall remission rate without increasing morbidity. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, IV.

Complex regional pain syndrome (Type 1) following steroid injection for stenosing tenosynovitis.

Complex regional pain syndrome (CRPS) is a chronic progressive disease characterised by severe pain, swelling and changes in the skin. Precipitating factors include injury and surgery, and a variety of causes have been described. We present the case of a 68-year-old lady who presented with features indicative of a CRPS following steroid injection for a 'trigger' thumb.

Prospective randomized study of 2 different techniques for endoscopic iliopsoas tendon release in the treatment of internal snapping hip syndrome.

PURPOSE: To evaluate the short-term results of 2 different techniques of endoscopic iliopsoas tendon release for the treatment of internal snapping hip syndrome. METHODS: Between January 2005 and January 2007, a consecutive series of patients with the diagnosis of internal snapping hip syndrome was treated with endoscopic release of the iliopsoas tendon. The patients were randomized into 2 different groups. Patients in group 1 were treated with endoscopic iliopsoas tendon release at the lesser trochanter, and patients in group 2 were treated with endoscopic transcapsular psoas release from the peripheral compartment. Hip arthroscopy of both the central and peripheral compartments was performed in both groups using the lateral approach. Associated injuries were identified and treated arthroscopically. Postoperative physical therapy was the same for both series, and each patient received 400 mg of celecoxib daily for 21 days after surgery. Preoperative and postoperative Western Ontario MacMaster (WOMAC) scores and imaging studies were evaluated. RESULTS: Nineteen patients were included in the study: 10 in group 1 (5 male and 5 female; average age, 29.5 years) and 9 in group 2 (8 female and 1 male; average age, 32.6 years). No statistical difference was found in group composition. Associated injuries were found and treated in 8 patients in group 1 and 7 patients in group 2. No statistical difference was found between groups in preoperative WOMAC scores, and every patient in both groups had an improvement in the WOMAC score. Improvements in WOMAC scores were statistically significant in both groups, and no difference was found in postoperative WOMAC results between groups. No complications were seen. CONCLUSIONS: Iliopsoas tendon release at the level of the lesser trochanter or at the level of the hip joint using a transcapsular technique is effective and reproducible. We found no clinical difference in the results of both techniques.

Percutaneous release of the trigger thumb: is it safe, cheap and effective?

Percutaneous release of the trigger finger and trigger thumb has recently gained popularity. The aim of this study was to determine the clinical results and safety of percutaneous release in trigger thumbs. Twenty-five thumbs of 21 patients were released percutaneously in the polyclinic under local anaesthesia. Steroid injection was performed following the release procedure using the same needle. The thumb function was evaluated by a patient questionnaire, and functional thumb scores (VAS) were calculated in the preoperative and postoperative periods. At the 1 week follow-up, four patients had signs of discomfort and triggering because of incomplete release. These patients underwent open A1 pulley release. Three superficial tendon lacerations were seen during these open procedures. There were no wound complications or signs of digital nerve or artery injury in any of the patients. The preoperative mean VAS was 26.62 (18-36). This decreased to 2.57 (0-5) at the first postoperative month (P<0.001) and to 2.19 (0-3; P<0.001) at the sixth month. When the VAS scores at the first and sixth months were compared, the difference was statistically significant. We concluded that percutaneous release of trigger thumbs is a cheap, safe and effective procedure with a low rate of complications.
