Aims

In the UK, fasciectomy for Dupuytren’s contracture is generally performed under general or regional anaesthetic, with an arm tourniquet and in a hospital setting. We have changed our practice to use local anaesthetic with adrenaline, no arm tourniquet, and perform the surgery in a community setting. We present the outcome of a consecutive series of 30 patients.

Aims

The aim of this study was to assess the quality and scope of the current cost-effectiveness analysis (CEA) literature in the field of hand and upper limb orthopaedic surgery.

Objectives

Injectable Bromelain Solution (IBS) is a modified investigational derivate of the medical grade bromelain-debriding pharmaceutical agent (NexoBrid) studied and approved for a rapid (four-hour single application), eschar-specific, deep burn debridement. We conducted an ex vivo study to determine the ability of IBS to dissolve-disrupt (enzymatic fasciotomy) Dupuytren’s cords.

In Canada, Dupuytren's contracture is managed with partial fasciectomy or percutaneous needle aponeurotomy (PNA). Injectable collagenase will soon be available. The optimal management of Dupuytren’s contracture is controversial and trade-offs exist between the different methods. Using a cost-utility analysis approach, our aim was to identify the most cost-effective form of treatment for managing Dupuytren’s contracture it and the threshold at which collagenase is cost-effective. We developed an expected-value decision analysis model for Dupuytren’s contracture affecting a single finger, comparing the cost-effectiveness of fasciectomy, aponeurotomy and collagenase from a societal perspective. Cost-effectiveness, one-way sensitivity and variability analyses were performed using standard thresholds for cost effective treatment ($50 000 to $100 000/QALY gained). Percutaneous needle aponeurotomy was the preferred strategy for managing contractures affecting a single finger. The cost-effectiveness of primary aponeurotomy improved when repeated to treat recurrence. Fasciectomy was not cost-effective. Collagenase was cost-effective relative to and preferred over aponeurotomy at $875 and $470 per course of treatment, respectively. . In summary, our model supports the trend towards non-surgical interventions for managing Dupuytren’s contracture affecting a single finger. Injectable collagenase will only be feasible in our publicly funded healthcare system if it costs significantly less than current United States pricing.

Dupuytrens disease is a fibrosing condition of the palmar aponeurosis and its extensions within the digits. Normal fascial fibres running longitudinally in the subcutaneous tissues of the palm become thickened and form the characteristic nodules and cords pathognomonic of Dupuytrens disease. A wide variety of surgical interventions exist, of these the partial fasciectomy remains the most conventional and widely used technique. Minimally invasive surgical treatments such as needle fasciotomy are, however, becoming increasingly popular. Dupuytrens disease remains a challenging condition to treat as recurrence is universally found with all surgical interventions. Although recurrence may be related to the severity of the disease, there are currently no research tools other than clinical examination to examine changes in the diseased tissue postoperatively and predict likelihood of long-term success. Magnetic Resonance Imaging (MRI) may be of value for the study of Dupuytren disease, at present its use has been greatly underexplored. We wished to carry out a pilot study in order to examine the possibility of using 3.0 Tesla MRI to study Dupuytren tissue and then furthermore to examine the potential changes post-operatively following percutaneous fasciotomy. Five patients set to undergo percutaneous needle fasciotomy were recruited and consented for the study. All patients underwent MRI scanning of the affected hand pre-operatively and at two weeks post-operatively. Scanning was carried out in the 3.0 Tesla research MRI scanner at Aberdeen Royal Infirmary. Patients were placed prone in the MRI scanner with the hand outstretched above the head in the so-called “Superman” position. A specially designed wrist and hand coil was used. Under the expertise of radiographers and physicists, image capture encompassed four novel scanning sequences in order to make a volumetric three-dimensional image sample of the affected hand. MIPAV software (Bethesda, Maryland) was used for image analysis. Scanning revealed well defined anatomy. The Dupuytren cord arose from the palmar aponeurosis tissue which is deep to the palmar skin and subcutaneous tissue. It was distinctly different to deep structures such as the flexor tendons and intrinsic hand muscles which appeared with a uniform low and high signal respectively. The Dupuytren tissue had a heterogeneous signal on both T1 and T2 images. On T1 the tissue signal appeared high to intermediate, similar to that of bone and muscle, but low areas of signal were observed diffusely in an irregular fashion throughout. On T2 the tissue had a low signal throughout with some focal areas of high signal. Dupuytren tissue was mapped using MIPAV software for pre- and post-operative comparisons. Signal intensity, surface area and volume of the cords and fasciotomy sites were explored. Our initial results suggest MRI can be used to study Dupuytren tissue. Such a research tool may be of use to study the natural history of Dupuytren disease and furthermore, the response to medical and surgical interventions

Objective. To assess the long term functional and objective outcomes for 2 stage Dupuytrens contracture correction. Methods. Patients with severe contracture were offered a 2 stage correction. This involved application of external fixator to distract the contracture over the course of 2 weeks and subsequent partial fasciectomy (in primary contractures) and dermofasciectomy with full thickness skin graft (in recurrent contractures). A series of 54 corrections in 47 patients were identified. Of these, 6 were lost to follow-up, 1 deceased. Pre-operative total range of active movement (TRAM), total flexion contracture and PIP flexion contracture, Tubiana grade and DASH/Michigan Hand Scores were recorded and compared to post-operative data. Results. Mean age was 61 (range 43–90), 44 male, 10 females. The average duration of follow-up was 32 months (range 6–96). The mean fixed flexion deformity (FFD) in the PIPJ improved from 84 degrees (range 50–110, SD-12) to 30 degrees (range −5–90, SD-27) (p< 0.0001). Mean total flexion contracture improved from 123 degrees(range 50–210, SD-34) to 46 degrees (range 0–195, SD-50) (p< 0.0001). The mean TRAM improved from 70 degrees (range 10–140, SD-33) to 148 degrees (range 25–135, SD-52) (p< 0.0001). DASH scores improved from 32.0 to 27.6. Michigan hand scores improved from 68 to 76. There was no statistical difference in pre- and post-op hand scores. Complications include CRPS (8%), infection (6%), stiffness (4%), graft failure (4%), neurovascular injury (2%), fracture (4%). Conclusions. Long term follow-up of this two stage technique shows that the correction, range of movement and function is maintained. We consider that the complications rate is acceptable for these very severe deformities where amputation, joint fusions and total collateral ligament and volar plate release are the only other comparable surgical alternatives

Introduction: Dupuytren’s contracture is a common disease in Northern Europe. Partial fasciectomy is often used to treat the whole spectrum of Dupyutren’s disease, although high recurrence rates have been reported. In our department, the majority of patients are treated by total aponeurectomy, which is defined as the complete removal of palmar tissue. It has been found out that apparently normal-looking aponeurosis can also contain an increased proportion of collagen, which may lead to recurrent disease. Consequently, the perceived advantage of total aponeurectomy over partial aponeurectomy is the potential for a lower recurrence rate as all diseased tissue is potentially removed. Against this background, we have reviewed the effectiveness of total aponeurectomy performed on 61 patients. Patients and Methods: The group of patients available for review consisted of 51 men and ten women with a mean age of 63.0 (range 42–79 years) and with a mean period of 3.45 years (range 1.03–6.39 years) between operation and review. No patient had follow-up of less than 1 year. At follow-up evaluation hands were examined for nodules, cords and retractions of the skin. The active mobility of the joints was determined with a goniometer and the Jamar hand dynamometer was used to measure grip strength in both hands. Sensitivity was examined by means of two-point-discrimination and the DASH-score was used for the analysis of rehabilitation. Patients were also asked about common risk factors for Dupuytren’s disease. Results: Post-operative complications including haematoma, seroma or necrosis were found in 13.8% of the patients. Recurrence of contracture occurred in 10.8% of the patients and 4.6% of the operated patients presented with a nerve lesion. Nerve irritation was found in 6.2% of the patients. The mean DASH-score was 3.85 (range 0–52.5). Family pre-disposition was an important risk factor for Dupuytren’s disease with 44.3% of patients having a positive family history. Conclusion: We suggest that total aponeurectomy is a promising alternative to partial fasciectomy with low risk for recurrent disease and slightly increased risk for a nerve lesion

Purpose of Study: To assess the efficacy of two-stage correction (skeletal traction followed by Partial Fasciec-tomy) in treating severe Dupuytren’s contractures. Material, Methods and Results: We retrospectively reviewed sixteen fingers in fifteen patients with severe Dupuytren’s contracture (Tubiana Grade III/IV), operated between April 2000 and July 2005. The mean age was 58 years (27 – 82 years). All patients underwent an initial application of Orthofix external fixator with pins in the proximal and middle phalanx. The patients were advised to gradually distract the device 3-4 times a day, for two weeks. They were then brought back for removal of fixator and partial fasciectomy with closure of skin by V-Y plasty. The results were assessed in thirteen patients, as two were lost to follow-up. The mean follow-up period was 30 months (6 – 64 months). The total mean preopera-tive extension deficit improved from 130 degrees to 38 degrees postop.; PIP joint deformity improved from a mean of 77 degrees to 33 degrees postop. and the mean TRAM (Total range of active movements) improved from 108 degrees to 165 degrees. Functional assessment was done using Michigan Hand Outcome Questionnaire. Overall improvement in hand function was from a preoperative 34% to a postoperative 89%.; aesthetic improvement from a preop. of 46% to a postop of 81% and pain improvement from a preop of 66% to a postop of 96%. One patient had recurrence, one had features of RSD (Reflex Sympathetic Dystrophy) and one had to undergo amputation due to poor tolerance and persistent infection. Conclusion: Severe Dupuytren’s contracture is a challenging deformity to deal. The two-stage correction may be considered as an alternative method of treatment in cooperative patients. Our study has shown promising results with good patient satisfaction

Introduction and Aims: Severe Dupuytren’s contracture of the proximal interphalangeal (PIP) joint is a difficult condition to treat; a two-stage technique has been advocated by some surgeons for such cases. The present study set out to determine the early results of this technique. Method: Thirteen patients (11 with primary and two with recurrent disease) with a severe Dupuytren’s contracture of the proximal interphalangeal (PIP) joint were treated by geometric correction (in line distraction followed by angular correction) using the OrthofixTM mini external fixator followed by its removal and partial fasciectomy (without collateral ligament or volar plate release). The mean duration of distraction was 14 days. Results: In the PIP joint the mean true fixed flexion deformity pre-operatively was 75 degrees (range 45–90). At a mean follow-up of 21 months, the mean residual flexion deformity was 35 degrees (range 10–90). The mean arc of motion increased from 26 (range 10–55) to 51 degrees (range 0–90). At follow-up, the mean arc of motion was 33 degrees (range 0–70) and 73 degrees (range 45–110) at the distal interphalangeal and meta-carpophalangeal joints respectively. There were no cases of reflex sympathetic dystrophy or neurovascular damage. One patient had a fracture of the proximal phalanx and a second patient had an early recurrence, which led to a poor clinical outcome. The rest had an excellent clinical outcome according to the Michigan Hand Questionnaire. Conclusion: Although the technique is challenging, the early results are promising and we recommend it for the management of this difficult problem

After having had a standard decompression for anterior compartment syndrome, five patients presented with persistent symptoms and pressure values above normal. A repeat procedure combined with fasciectomy relieved their pain; postoperative pressure values were normal.
