Volkmann’s contracture of the forearm due to an insect bite: a case report and review of the literature

Compartment syndrome affecting the upper limb is reported rarely in the literature and is usually limited to single case reports. Upper limb compartment syndrome secondary to envenomation is rare, especially in the UK. Worldwide, it has been reported resulting from snake and insect bites, mostly from snakes from the Viperidae family, and from insects such as bees and wasps. Reports from the UK are limited to one case of an adder bite.We present a case of a previously fit and well adult who developed an ischaemic contracture of the forearm after an insect bite. Surgical exploration revealed segmental necrosis and contracture of the superficial and deep flexors of the fingers, requiring fasciotomy and tendon-lengthening procedures. This is the first report of a compartment syndrome, or a late ischaemic contracture from an insect bite in the UK. Owing to the rarity of compartment syndrome of the upper limb secondary to envenomation, a delay in diagnosis and treatment can lead to irreversible changes in the muscular compartments of the forearm.     

Clinical review: Volkmann’s ischaemic contracture

Introduction  

Volkmann’s ischaemic contracture is a devastating condition with serious motor and sensory functional implications for the affected limb. This clinical review outlines acute compartment syndrome and Volkmann’s ischaemic contracture, their presentation, evolution and current management.     

Volkmann’s contracture in high-voltage electrical injury

Burn injuries are a common form of trauma, it occurs in 1% of the population of Australasia each year. Of these injuries, the devastating effects of high-voltage electrical burns in deep-tissue injury causing compartment syndrome and subsequent Volkmann’s ischemic contracture are well documented. This report highlights the importance of early recognition of the severe electrical burn injury and its clinical consequences. Early identification through vigilant monitoring and diagnostic adjuncts, together with early intervention, whether conservative monitoring or operative management is of utmost importance in the prevention of ongoing complications and recovery from injury.     

Modified percutaneous needle aponeurotomy for the treatment of dupuytren’s contracture: early results and complications

Background

The purpose of our study was to identify postoperative results and complications using a percutaneous approach to treat Dupuytren''s contracture in a consecutive series of patients.

Methods

A review of all patients with Dupuytren''s contracture treated with percutaneous needle aponeurotomy (NA) from 2008 to 2010 was performed. Patient demographics, digits affected, and disease severity was recorded. Pre-operative total passive extension deficit (TPED) was calculated for each affected digit. TPED in the immediate postoperative period and at the time of most recent follow-up was measured. Treatment-related complications and incidence of disease recurrence were identified. Statistical analysis was performed using paired t-test. (Statistical significance p-value <0.05).

Results

525 digits in 193 hands were treated with NA. 140 patients were male, average age was 65 years. The average preoperative TPED was 41° and the average immediate postoperative TPED was 1° (98% correction) (P=0.0001). The average TPED at 4.5 month follow up was 11 o (73% correction). Complications included infection in 3 patients and one case each of triggering, delayed flexor tendon rupture, complex regional pain syndrome and persistent numbness. Recurrence was observed in 62 digits.

Conclusion

Percutaneous needle aponeurotomy is an effective technique in the treatment of Dupuytren''s contracture. Near complete correction of contracture was achieved and few complications were observed. Longer follow-up is needed to determine if these short-term results are maintained.     

Examining the efficacy and maintenance of contracture correction after collagenase clostridium histolyticum treatment for Dupuytren’s disease

Background

This study examined the efficacy, complications, and contracture recurrence in patients who received injectable collagenase clostridium histolyticum (CCH) for Dupuytren’s-induced metacarpophalangeal (MP) and proximal interphalangeal (PIP) joint contractures.

Methods

A retrospective chart review at one center compared the degree of MP and PIP joint contracture pre-injection, post-cord rupture, and at final follow-up after a minimum duration of 6 months. Recurrence was defined as a 20 ° or greater increase in contracture above the minimum value achieved.

Results

Of 102 eligible patients, 48 patients (47 %) (31 males, 17 females) were available for review. 53 digits and 64 joints (46 MP joints and 18 PIP joints) were studied. The mean patient age was 66 years (range, 48–87 years) and mean follow-up duration was 15 months (range, 6 to 25 months). The mean MP joint contracture was 51 ± 20 ° at baseline, 4 ± 8 ° post-cord rupture, and 9 ± 15 ° at latest follow-up. The mean PIP joint contracture was 39 ± 23 ° at baseline, 14 ± 14 ° at cord rupture, and 29 ± 20 ° at latest follow-up. Of the 46 MP joints and 18 PIP joints, 11 MP (24 %) and 7 (39 %) PIP joints met the recurrence criteria. Of 102 patients, 1 patient had a small finger flexor tendon rupture.

Conclusions

Despite the dramatic initial reduction in contracture, recurrence developed in a high proportion of patients over the study period. While initially effective, CCH may not provide durable contracture reduction. However, CCH remains a viable nonsurgical treatment for Dupuytren’s disease.     

Results of treatment of chronic osteomyelitis by “gutter procedure and muscle flap transposition operation”

Introduction

The aim of this study was to evaluate the outcomes of creation of a gutter and muscle flap transposition method for the treatment of long-bone chronic osteomyelitis.

Patients and methods

A total of thirty chronic osteomyelitis patients (thirty-one extremities), who had undergone the gutter creation and muscle flap transposition procedure between 2005 and 2009, were included in the study (19 male, 11 female; mean age 24.4 years; age range 2–75 years). Osteomyelitis of the long bones involved the femur in 13 patients, the tibia in 13, the humerus in 2, the fibula in 2 and the ulna in 1 patients, respectively. All the patients received post-operative antibiotic therapy of at least 6 weeks. The mean follow-up period was 28.7 months (6–53 months). At the end of this follow-up period, the patients were evaluated using clinical, laboratory and screening methods.

Results

Complete pain relief, disappearance of toxic symptoms, improvement in radiological findings, fistula closure and return of the blood parameters to normal ranges were accepted as successful treatment when all the afore-mentioned had been fulfilled. According to these criteria, 29 of the 30 patients had been cured.

Discussion

The gutter creation and muscle flap transposition method in the treatment of long-bone chronic osteomyelitis may be a successful mode of therapy when performed correctly and supported by long-term antibiotherapy.

Collagenase treatment of Dupuytren’s contracture using a modified injection method

Background and purpose — Treatment of Dupuytren’s contracture (DC) with collagenase Clostridium histolyticum (CCH) consists of injection followed by finger manipulation. We used a modified method, injecting a higher dose than recommended on the label into several parts of the cord, which allows treatment of multiple joint contractures in 1 session and may increase efficacy. We studied the occurrence of skin tears and short-term outcome with this procedure.

Patients and methods — We studied 164 consecutive hands with DC, palpable cord, and extension deficit of ≥ 20º in the metacarpophalangeal (MCP) and/or proximal interphalangeal (PIP) joint (mean patient age 70 years, 82% men). A hand surgeon injected all the content of 1 CCH vial (approximately 0.80 mg) into multiple spots in the cord and performed finger extension under local anesthesia after 1 or 2 days. A nurse recorded skin tears on a diagram and conducted a standard telephone follow-up within 4 weeks. A hand therapist measured joint contracture before injection and at a median of 23 (IQR: 7–34) days after finger extension.

Results — A skin tear occurred in 66 hands (40%). The largest diameter of the tear was ≤ 5 mm in 30 hands and > 10 mm in 14 hands. Hands with skin tear had greater mean pretreatment MCP extension deficit than those without tear: 59º (SD 26) as opposed to 32º (SD 23). Skin tear occurred in 21 of 24 hands with MCP contracture of ≥ 75º. All tears healed with open-wound treatment. No infections occurred. Mean improvement in total (MCP + PIP) extension deficit was 55º (SD 28).

Interpretation — Skin tears occurred in 40% of hands treated with collagenase injections, but only a fifth of them were larger than 1 cm. Tears were more likely in hands with severe MCP joint contracture. All tears healed without complications. Short-term contracture reduction was good.     

Results of total aponeurectomy for Dupuytren’s contracture in 61 patients: a retrospective clinical study

Introduction  Many surgical techniques have been advocated to treat Dupuytren’s contracture. Partial fasciectomy is often performed to treat the whole spectrum of Dupuytren’s disease. Method  We have reviewed the effectiveness of total aponeurectomy performed on 61 patients [10 women and 51 men (male:female ratio 5.1:1) with a mean age of 63.0 (range 42–79 years) and a mean follow-up of 3.45 years (range 1.03–6.39 years)]. 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 occurred 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 a recurrence and slightly increased risk for a nerve lesion.     

Clinical outcomes following collagenase injections compared to fasciectomy in the treatment of Dupuytren’s contracture

IntroductionThe aim of this study is to compare the efficacy of collagenase injections with that of fasciectomy in the treatment of Dupuytren’s contracture.MethodsThis is a case–control retrospective study. We reviewed the electronic medical records from January 2009 through January 2013, identifying 142 consecutive patients who underwent either fasciectomy or collagenase injection. Exclusion criteria for both groups were age <18 years, pregnant women, and arthroplasty or arthrodesis of the treated joint. Follow-up data beyond 1-year duration was available for 117 of the patients: 44 patients who had undergone fasciectomy, and 73 patients who had received collagenase injection. The primary outcome measure in this study was resolution of joint contracture to 0–5° deficit of full extension. Data was analyzed using two-sample t tests for continuous data and chi-square test for categorical data. A significant P value was set at <0.05.ResultsAt the latest follow-up, significantly more joints treated with fasciectomy met the primary outcome measure. Metacarpophalangeal (MP) joints responded better than the proximal interphalangeal (PIP) joints for both treatments. At the latest follow-up (14.2 months for collagenase, 16.3 months for fasciectomy), 46 % of MP joints treated with collagenase and 68 % of MP joints treated with fasciectomy maintained resolution of joint contracture. Sub-analysis of the affected joints based on the severity of initial contracture demonstrated that MP and PIP joints with contractures <45° responded better than more severely contracted joints (>45°).ConclusionsFasciectomy yields a greater mean magnitude of correction for digital contractures at the latest follow-up when compared to collagenase. Both treatments were more effective for treatment of MP joint contracture compared to PIP joint contracture.

Women’s experiences of doing long-term pelvic floor muscle exercises for the treatment of pelvic organ prolapse symptoms

Introduction and hypothesis

This study investigated women’s experiences of doing prescribed pelvic floor muscle exercise (PFME) after participation in the Pelvic Organ Prolapse Physiotherapy (POPPY) trial. The aim was to understand post-supervised treatment adherence to PFME and to inform future advice for women being treated for pelvic organ prolapse (POP).

Methods

Five women were purposively selected from the New Zealand branch of the multi-centre, multi-national POPPY trial and took part in a semi-structured interviews about their experiences of PFME. The interviews were subjected to an interpretative phenomenological analysis (IPA).

Results

Three core themes were identified in the analysis. The first theme, “Patterns of PFME behaviour”, described exercise characteristics and behaviours. The second theme, “Influences on PFME maintenance cycles”, captured the participants’ responses to and evaluations of their exercise practice and related PFME self-efficacy. The “cycle” referred to the changing influences on exercise behaviour. The third theme, “Family as priority”, was expressed in terms of either putting family first or successfully combining the priorities of family and self.

Conclusion

This study revealed the importance of family in influencing PFME patterns and behaviours in the treatment of POP. It is possible that identifying strategies to help women reach their PFME goals within the context of their families will promote more successful PFME adherence. The importance of family when prescribing exercise for women with other chronic health conditions is also worth exploring.     

Functional outcome of collagenase injections compared with fasciectomy in treatment of Dupuytren’s contracture

Background

This study was designed to provide comparative information on the safety and efficacy of injection with collagenase clostridium histolyticum (CCH) and fasciectomy for patients with Dupuytren’s contracture (DC).

Methods

A single-center, retrospective, observational, longitudinal chart review was conducted of 25 patients treated with CCH injections and 21 patients undergoing fasciectomy. Patients were assessed at 1 week, monthly for 3 months and then yearly for a minimum of 2 years after treatment for changes in contracture and range of motion, time to return to work/normal activities, patient satisfaction, and Disabilities of Arm, Shoulder and Hand (DASH) score.

Results

Post-procedure follow-up averaged 32 months for the injection group compared with 39 months for fasciectomy group. For the CCH group, the mean postinjection contracture was 3.6° for the metacarpophalangeal and 17.5° for the proximal interphalangeal joints compared with 3.7° and 8.1° in the fasciectomy group, respectively. Patients treated with injections returned to normal activities after a mean of 1.9 days compared with 37.4 days for fasciectomy patients (p < 0.0001). DASH scores for 13 CCH and 15 fasciectomy patients were obtained. The mean DASH score was significantly lower in the injection group in the first 3 months (p < 0.01). At the 2-year follow-up visit, patients were satisfied with their outcomes following either treatment (92 % and 96 % of CCH and fasciectomy patients, respectively).

Conclusion

CCH injections are safe and effective and may be a viable alternative to fasciectomy for treating DC. It also allows earlier return to work and daily activities.     

Use of platelet-rich plasma for the treatment of refractory jumper’s knee

The aim of this study was to evaluate the efficacy of multiple platelet-rich plasma (PRP) injections on the healing of chronic refractory patellar tendinopathy after previous classical treatments have failed. We treated 15 patients affected by chronic jumper’s knee, who had failed previous nonsurgical or surgical treatments, with multiple PRP injections and physiotherapy. We also compared the clinical outcome with a homogeneous group of 16 patients primarily treated exclusively with the physiotherapy approach. Multiple PRP injections were performed on three occasions two weeks apart into the site of patellar tendinopathy. Tegner, EQ VAS and pain level were used for clinical evaluation before, at the end of the treatment and at six months follow-up. Complications, functional recovery and patient satisfaction were also recorded. A statistically significant improvement in all scores was observed at the end of the PRP injections in patients with chronic refractory patellar tendinopathy and a further improvement was noted at six months, after physiotherapy was added. Moreover, comparable results were obtained with respect to the less severe cases in the EQ VAS score and pain level evaluation, as in time to recover and patient satisfaction, with an even higher improvement in the sport activity level achieved in the PRP group. The clinical results are encouraging, indicating that PRP injections have the potential to promote the achievement of a satisfactory clinical outcome, even in difficult cases with chronic refractory tendinopathy after previous classical treatments have failed.     

Importance of a multidisciplinary approach for the treatment of Barrett’s esophagus

Barrett's esophagus is a consequence of gastroesophageal reflux disease. Today, it is the most common cause of esophageal adenocarcinoma. Cancer is usually the end results of a cascade of events whereby metaplasia changes into low- and high-grade dysplasia and eventually cancer. Today, we have the unique opportunity to block this cascade and avoid the development of esophageal cancer. A multidisciplinary approach with a team composed of radiologists, gastroenterologists, pathologists, and surgeons allows individualization of care and the best results.     

Marjolin’s ulcer of the forearm from 30-year-neglection of external fixator

BackgroundMarjolin’s ulcers are a rare form of malignancy that present at regions exposed to chronic infection. They present with a clinical triad of nodularity, induration, and ulceration greater than 3 months.Case reportWe present herein, an extremely rare case of Marjolin’s ulcer of the forearm, secondary to osteomyelitis, resulting from a 30-year neglection of external fixator used to treat a war injury of the forearm.DiscussionMarjolin’s ulcers are classically encountered in lower extremities at sites of burns, trauma or complicated wounds. In the upper extremity however, they are seldom mentioned in literature. The presence of risk factors raise the suspicion of the disease.ConclusionMarjolin’s ulcer is rare sequelae of chronic wound infection. Patients often present after a latency period with exacerbated pain, discharge, and exophytic mass. This disease should be suspected in every case of chronic ulcer, where histological studies of the lesion must be conducted to exclude or confirm the diagnosis.     

Nonsurgical treatment of Dupuytren’s contracture: 1-year US post-marketing safety data for collagenase clostridium histolyticum

Background

Collagenase clostridium histolyticum (CCH) is a Food and Drug Administration-approved treatment for adult patients with Dupuytren’s contracture with a palpable cord that has been shown efficacious and safe in clinical trials.

Methods

This paper summarizes the most common post-marketing clinical adverse event (AE) reports received by the manufacturer of CCH and sponsor of the US Biologics License Application (Auxilium Pharmaceuticals, Malvern, PA, USA) during the first 12 months after drug approval and commercialization in the USA.

Results

Of the 115 AE reports describing 270 AEs voluntarily received from patients or health care providers after approximately 5,400 injections of CCH administered, the most common AEs involved local, nonserious reactions to treatment, including skin tears, peripheral edema, and contusion. There were few serious AEs observed (0.6% reporting rate per 1,000 injections), and two flexor tendon ruptures and one flexor pulley injury were reported.

Conclusions

Analysis of post-marketing AEs received for CCH in the first year post-approval supports the safety profile reported earlier during clinical development and did not reveal additional clinical risks or concerns about CCH.     

Robot-assisted whipple’s operation for solid pseudopapillary tumour of pancreas

Solid pseudopapillary tumor is a rare tumor of the pancreas. They are slow growing with low malignant potential. The prognosis is excellent after surgical resection. Here we report a case of solid pseudopapillary tumor of the pancreas at the uncinate process. There are increasing interests about minimal access surgery for pancreatic lesion. However conventional laparoscopic Whipple’s operation is technically difficult. With the benign characteristic of this tumor, as well as the advance in robotic surgery, robot assisted approach is an ideal alternative for this case. The operation was performed with a five-port approach with the use of da Vinci S Surgical System (Intuitive Surgical Inc., Sunnyvale, CA, USA). The operative time was 420 min and operative blood loss was 100 ml. The post operative course was uneventful and the patient was discharged on post operative day 10. This case demonstrates the feasibility of robot assisted Whipple’s operation, which has not been extensively reported in the literature.
