Seven-year clinical outcomes after collagenase injection in patients with Dupuytren's disease: A prospective study

Long-term assessment of collagenase treatment for Dupuytren's contracture: A 10-year follow-up study

BACKGROUND

Enzymatic fasciotomy with collagenase clostridium histolyticum (CCH) has revolutionized the treatment for Dupuytren's contracture (DC). Despite its benefits, the long-term outcomes remain unclear. This study presented a comprehensive 10-year follow-up assessment of the enduring effects of CCH on patients with DC.

AIM

To compare the short-term (12 wk) and long-term (10 years) outcomes on CCH treatment in patients with DC.

METHODS

A cohort of 45 patients was treated with CCH at the metacarpophalangeal (MCP) joint and the proximal interphalangeal (PIP) joint and underwent systematic re-evaluation. The study adhered to multicenter trial protocols, and assessments were conducted at 12 wk, 7 years, and 10 years post-surgery.

RESULTS

Thirty-seven patients completed the 10-year follow-up. At 10 years, patients treated at the PIP joint exhibited a 100% recurrence. However, patients treated at the MCP joint only showed a 50% recurrence. Patient satisfaction varied, with a lower satisfaction reported in PIP joint cases. Recurrence exceeding 20 degrees on the total passive extension deficit was observed, indicating a challenge for sustained efficacy. Significant differences were noted between outcomes at the 7-year and 10-year intervals.

CONCLUSION

CCH demonstrated sustained efficacy when applied to the MCP joint. However, caution is warranted for CCH treatment at the PIP joint due to a high level of recurrence and low patient satisfaction. Re-intervention is needed within a decade of treatment.

Comparing Complications and Patient Satisfaction Following Injectable Collagenase Versus Limited Fasciectomy for Dupuytren's Disease: A Systematic Review and Meta-Analysis

Dupuytren's disease (DD) is a fibroproliferative disorder that manifests as an abnormal growth of myofibroblasts, causing nodule formation and contractures and affecting digit function. If left untreated, these contractures can lead to a loss of mobility and potentially impact hand function. This systematic review critically compares and evaluates the existing literature on the complications and patient satisfaction following injectable collagenase Clostridium histolyticum (CCH) versus limited fasciectomy (LF) for DD. We performed a comprehensive search of the PubMed, Medical Literature Analysis and Retrieval System Online (MEDLINE), The Cochrane Library, and Excerpta Medica database (EMBASE) databases from 2006 to August 2023. This research targeted all clinical studies involving adults who underwent injectable collagenase and/or limited fasciectomy in the management of DD. Out of the 437 identified studies, only 53 were considered eligible for our analysis, and merely 14 met our inclusion criteria. These selected studies encompassed a total of 967 patients with 1,344 treated joints, with an average follow-up duration of 19.22 (ranging from one to 84.06) months. Within this cohort, 498 joints from 385 patients underwent LF, while 846 joints from 491 patients received CCH injections. Notably, among the 491 patients treated with CCH, 1,060 complications were reported, averaging 2.15 complications per patient, with the most common being contusion/bruising/hematoma/ecchymosis (22.54%), and edema/swelling (18.96%). In contrast, among the 385 patients treated with LF, only 97 complications were reported, translating to 0.25 complications per patient, with the most frequent being paraesthesia or numbness (23.7%), scar sequelae like skin laceration, tear, fissure, or hypertrophic scar (23.7%), and neuropraxia or nerve injury (22.6%). Our meta-analysis indicates that paraesthesia or numbness is more frequently observed in LF than CCH injections, although without statistical significance, with a risk ratio (RR) of 0.39 (95% confidence interval (CI) 0.13-1.18, p-value 0.1). However, scar sequelae (hypertrophic scar, skin laceration, tear, or fissure) show a contrasting pattern, being more commonly associated with CCH injections than LF, with an RR of 1.98 (95% CI 0.26-14.85, p-value 0.51), which, upon eliminating the source of heterogeneity, becomes statistically significant, with an RR of 4.98 (95% CI 1.40-17.72, p-value 0.01). Our data revealed a higher frequency of complications with CCH compared to LF, although more severe adverse effects were observed in the LF group, such as neuropraxia or nerve injury. Scar sequelae were more common with CCH injections. Despite both treatments showing increased patient satisfaction at the final follow-up, CCH injection resulted in earlier improvements in satisfaction.

Delayed vascular complication after collagenase injection for Dupuytren disease

BACKGROUND

Vascular adverse events after collagenase injection for Dupuytren disease are absent in large trials and systematic reviews. The aim of this study is to present a case series of delayed vascular complications after collagenase treatment.

METHODS

A prospective evaluation of 1181 consecutively treated patients at one orthopedic department identified three patients reporting symptoms of possible vascular complication. Baseline demographics and description of symptoms were collected, with a physical examination documenting extension deficit and neurovascular status. All patients completed the Cold Intolerance Symptom Severity (CISS) scale (range 4-100, lower is better) and underwent Doppler sonography examination of the digital arteries.

RESULTS

All patients were treated in the small finger and two had an isolated proximal interphalangeal joint contracture. All patients had a delayed presentation of a few months, with episodes of white discoloration of the treated finger relieved within 30 min and associated with variable pain, paresthesia, stiffness and weakness. Two of the patients reported cold exposure as an episode trigger and had a pathological CISS score (40 and 36, respectively). Doppler sonography identified a nonpatent ulnar digital artery in one patient.

CONCLUSIONS

Delayed vascular complication after collagenase treatment is rare, but surgeons and patients should be aware of the risk, especially when treating the small finger.

Does the Use of Gelled Platelet-Rich Plasma during Fixation of Subacute Proximal Pole Scaphoid Fractures Help? – A Single Centre Experience

Background: Subacute proximal pole scaphoid fractures (1 month to 6 months) have a higher risk of non-union. The aim of the present retrospective analysis is to evaluate the efficacy of gelled platelet-rich plasma (GPRP) as additional treatment to antegrade headless screw fixation of proximal pole scaphoid fractures.

Methods: Forty-one patients were divided into two groups based on surgical treatment received: screw fixation alone (group A) and screw fixation and GPRP application at the fracture site (group B). A short cast was maintained for 4 weeks after surgery. Outcome measures included time to union, need for additional procedures, time to return to work, disabilities of the arm, shoulder, and hand (DASH) questionnaire, Michigan Hand Questionnaire (MHQ) and Mayo wrist score (MWS).Time to union was determined by monthly radiographs and confirmed by a computerized tomographic (CT) scan done at 4 months.

Results: Union was achieved in 85.7% of patients in group A and in 100% of patients in group B. Patients in group B showed a faster time to healing (2.3 ± 0.4 months vs 3.1 ± 0.7 months, p = 0.0001) and earlier return to work (10.4 ± 2.2 vs 15.1 ± 2.9, p = 0.0001). There were no significant differences in patient-rated outcomes scores between the two groups at final follow-up.

Conclusions: Internal fixation alone is effective in treating subacute proximal pole scaphoid fractures. GPRP application improves bone healing and functional recovery.

Epidemiology and aetiology of male and female sexual dysfunctions related to pelvic ring injuries: a systematic review

Introduction

Pelvic ring injuries, frequently caused by high energy trauma, are associated with high rates of morbidity and mortality (5–33%), often due to significant blood loss and disruption of the lumbosacral plexus, genitourinary system, and gastrointestinal system. The aim of the present study is to perform a systematic literature review on male and female sexual dysfunctions related to traumatic lesions of the pelvic ring.

Methods

Scopus, Cochrane Library MEDLINE via PubMed, and Embase were searched using the keywords: “Pelvic fracture,” “Pelvic Ring Fracture,” “Pelvic Ring Trauma,” “Pelvic Ring injury,” “Sexual dysfunction,” “Erectile dysfunction,” “dyspareunia,” and their MeSH terms in any possible combination. The following questions were formulated according to the PICO (population (P), intervention (I), comparison (C), and outcome (O)) scheme: Do patients suffering from pelvic fracture (P) report worse clinical outcomes (C), in terms of sexual function (O), when urological injury occurs (I)? Is the sexual function (O) influenced by the type of fracture (I)?

Results

After screening 268 articles by title and abstract, 77 were considered eligible for the full-text analysis. Finally 17 studies that met inclusion criteria were included in the review. Overall, 1364 patients (902 males and 462 females, M/F ratio: 1.9) suffering from pelvic fractures were collected.

Discussion

Pelvic fractures represent challenging entities, often concomitant with systemic injuries and subsequent morbidity. Anatomical consideration, etiology, correlation between sexual dysfunction and genitourinary lesions, or pelvic fracture type were investigated.

Conclusion

There are evidences in the literature that the gravity and frequency of SD are related with the pelvic ring fracture type. In fact, patients with APC, VS (according Young-Burgess), or C (according Tile) fracture pattern reported higher incidence and gravity of SD. Only a week association could be found between GUI and incidence and gravity of SD, and relationship between surgical treatment and SD. Electrophysiological tests should be routinely used in patient suffering from SD after pelvic ring injuries.

External Screw-Threaded Traction Device Helps Optimize Finger Joint Mobility in Severe Stage III and IV Dupuytren Disease

Background

Treating advanced finger joint contractures from Dupuytren disease remains a challenge. We evaluated the effectiveness of a skeletal distraction device versus alternative treatment options.

Material/Methods

We analyzed the surgical treatment of contracted finger joints in stage III and stage IV Dupuytren’s disease over a 10-year period. Data were obtained from inpatient and outpatient medical records, including postoperative clinical examinations and extended Disabilities of the Arm, Shoulder, and Hand (DASH) questionnaire scores. Complications of infection, postoperative pain, and wound healing disorders were recorded.

Results

A total of 79 patients (83 hands) were assigned to 2 treatment groups. Patients in group 1 underwent an initial open transection of the main fibrous cord, Z-plasty, distraction with the Erlangen external distraction device, and fasciectomy. The distraction period was 13 to 81 days (mean 31 days). Group 2 underwent a conventional single-stage fasciectomy and arthrolysis. DASH scores and subjective patient satisfaction were lower in group 1 (20.7/33%) than in group 2 (10.3/50%). However, the staged approach of group 1 to treat proximal interphalangeal joint contractures in the long term (improvement >40%) was more effective than the approach of group 2 (>33%). Distraction device pin infections occurred in 20% of hands. Postoperative pain and complex regional pain syndrome type I occurred in 25% of hands in group 1 and 3% in group 2.

Conclusions

A screw thread driven external fixation device is useful in end-stage Dupuytren’s finger joint contractures. It is indicated when joint contractures are advanced and simple arthrolysis is insufficient.

Feasibility of Homodigital Flexor Digitorum Superficialis transposition, a new technique for A2-C1 pulleys reconstruction: A kinematic cadaver study

INTRODUCTION

Homodigital flexor digitorum superficialis transposition (HFT) is proposed as a new technique for A2-C1 pulley reconstruction. Flexor digitorum superficialis is transposed on the proximal phalanx and inserted on the pulley rims, crossing over flexor digitorum profundus and acting as a pulley.

MATERIALS AND METHODS

The kinematic feasibility was investigated in a cadaveric bowstring model (after A2 and C1 pulley removal) on 22 fingers (thumb excluded).

RESULTS

HFT was effective in restoring the correct flexion of proximal and distal interphalangeal joints, compared to bowstring model. No adverse events were registered.

CONCLUSION

HFT is a feasible technique. Clinical application is encouraged.
