Intramuscular tenotomy of flexor digitorum superficialis in the distal forearm after surgical excision of dupuytren's disease

Botulinum toxin as an adjunct for severe Dupuytren's contracture treated with collagenase injections

Even with Dupuytren's proximal interphalangeal joint (PIPJ) contractures successfully released, volar flexor muscle memory can contribute to persistent contracture. We report using botulinum toxin (BoNTA) to the flexor digitorum superficialis muscle (FDS) to reduce flexor tone during recovery. Case Description. Two Collagenase clostridium histolyticum (CCH) injections were given to a patient with a -90° (PIPJ) contracture and a -35° degree distal interphalangeal joint (DIPJ) contracture. At the first CCH injection, 20 μ total of the Botulinum toxin was placed into the FDS muscle. Manipulation occurred at one week. A second injection of CCH followed by manipulation one week later occurred at two months, but no additional BoNTA was given. The final follow-up measurements at 53 months showed a PIPJ of -30° and a DIPJ of 0°. Total active motion improved from 140° to 240°. Outcomes of any treatment for severe Dupuytren's PIPJ contractures of the little finger are unpredictable and are often considered for staged external expansion or even salvage procedures. BoNTA injections weaken flexor tone in tendon repairs and for treating hypertonic muscles after strokes. Conclusion. We hypothesized that BoNTA injection could enhance the outcomes of DC treatment by inhibiting volar flexion forces during the recovery phase. The following case illustrates that using a BoNTA injection may have helped treat a severe PIPJ contracture. BoNTA injections need further research and controlled clinical trials to discover their proper role in Dupuytren's contractures treated via CCH injections, fasciotomies, and fasciectomies.

Angular correction related to excision of specific cords in fasciectomy for Dupuytren's disease

Named cords were excised sequentially at fasciectomy for Dupuytren's disease and the resultant correction in the joint angle was measured intra-operatively in 99 fingers. Eighty-two metacarpophalangeal and 59 proximal interphalangeal joints were affected. At the metacarpophalangeal joint, excision of the central cord resulted in 82% correction in 69 joints, and spiral/lateral cord excision resulted in an additional 12% correction in 10 joints. At the proximal interphalangeal joint, excision of the central cord resulted in 44% correction in 36 joints, spiral/lateral cord excision resulted in an additional 19% correction in 16 joints, and retrovascular cord excision resulted in a further 23% correction in 27 joints. Subsequent division of the accessory collateral ligament resulted in a further 14% correction in 14 joints. Larger pre-operative angles of the proximal interphalangeal joint were associated with a retrovascular cord, and larger combined angles were associated with an increasing number of pathological structures involved. The data explain the complexity of surgery at the proximal interphalangeal joint, where four structures are implicated in causing flexion deformity.

Correction of contracture and recurrence rates of Dupuytren contracture following invasive treatment: the importance of clear definitions

PURPOSE

To call attention to the wide variety of definitions for recurrence that have been employed in studies of different invasive procedures for the treatment of Dupuytren contracture and how this important limitation has contributed to the wide range of reported results.

METHODS

This study reviewed definitions and rates of contracture correction and recurrence in patients undergoing invasive treatment of Dupuytren contracture. A literature search was carried out in January 2011 using the terms "Dupuytren" AND ("fasciectomy" OR "fasciotomy" OR "dermofasciectomy" OR "aponeurotomy" OR "aponeurectomy") and limited to studies in English.

RESULTS

The search returned 218 studies, of which 21 had definitions, quantitative results for contracture correction and recurrence, and a sample size of at least 20 patients. Definitions for correction of contracture and recurrence varied greatly among articles and were almost always qualitative. Percentages of patients who achieved correction of contracture (ie, responder rate) when evaluated at various times after completion of surgery ranged from 15% to 96% for fasciectomy/aponeurectomy. Responder rates were not reported for fasciotomy/aponeurotomy. Recurrence rates ranged from 12% to 73% for patients treated with fasciectomy/aponeurectomy and from 33% to 100% for fasciotomy/aponeurotomy. Review of these reports underscored the difficulty involved in comparing correction of contracture and recurrence rates for different surgical interventions because of differences in definition and duration of follow-up.

CONCLUSIONS

Clearly defined objective definitions for correction of contracture and for recurrence are needed for more meaningful comparisons of results achieved with different surgical interventions.

CLINICAL RELEVANCE

Recurrence after surgical intervention for Dupuytren contracture is common. This study, which evaluated reported rates of recurrence following surgical treatment of Dupuytren contracture, provides clinicians with practical information regarding expected long-term outcomes of surgical treatment choices.
