Lacertus notch as a sign of lacertus syndrome.

OBJECTIVE: Many clinicians are unfamiliar with a diagnosis of lacertus syndrome (LS). We investigated the value of the lacertus notch sign in diagnosing LS. METHODS: We included 56 consecutive patients (112 upper extremities) who had neuropathic pain and neurological symptoms of the hand. The presence of LS and the lacertus notch sign in each upper extremity was assessed. RESULTS: Of the 83 upper extremities with LS, 54 (65.1%) had a lacertus notch sign, whereas 29 (34.9%) did not. Of the 29 upper extremities without LS, 9 (31.0%) and 20 (69.0%) had and did not have a lacertus notch sign, respectively. The rates of lacertus notch presence in upper extremities with and without LS were significantly different. Of the 63 upper extremities with a lacertus notch sign, 54 (85.7%) were diagnosed with LS, whereas 9 (14.3%) were not. Of the 49 upper extremities without a lacertus notch sign, 20 (40.8%) were diagnosed with LS, and 29 (59.2%) were not. We observed significant differences in the rates of LS in upper extremities with and without lacertus notch. CONCLUSIONS: The presence of the lacertus notch sign is useful for diagnosing LS. When patients with neuropathic pain and neurological symptoms present with a lacertus notch sign, clinicians should consider the possibility of LS.

Tips, Tricks, and Pearls for a Superior Patient and Surgeon Experience for Wide-awake Dupuytren Surgery.

Fasciectomy for Dupuytren disease is a common procedure traditionally performed with a tourniquet under general or regional anesthesia. Since the year 2001, the wide-awake local anesthesia no tourniquet (WALANT) approach has been applied successfully to Dupuytren surgery, with current excellent surgeon and patient satisfaction. However, using WALANT for Dupuytren surgery may be intimidating for hand surgeons who want to begin using this method. The purpose of this article is to offer a series of tips and tricks the authors have learned after having performed hundreds of WALANT fasciectomies, to make this technique easier for surgeons and a more pleasurable experience for patients.

Description of WALANT technique in open bone and ligament wrist surgery.

The gold-standard for bone, ligament and joint surgery in the wrist is locoregional anesthesia in most countries. Wide-Awake Local Anesthesia No Tourniquet (WALANT) is commonly used for simple soft-tissue hand surgery procedures such as carpal tunnel or trigger finger release, and can now also be safely used in procedures such as proximal row carpectomy, scapholunate ligament repair or partial wrist fusion, to name but a few. This article describes the use of WALANT for complex surgery in the wrist. WALANT surgery offers many known benefits, such as enhanced patient safety and comfort, simplified perioperative process and avoidance of anesthesia-related risks, and also allows the surgeon to perform intraoperative testing of the repaired structures. Thus, the surgeon can tailor the rehabilitation program and shorten recovery time. We describe detailed guidelines for performing WALANT procedures safely and effectively, making it a favorable option for complex surgeries in the wrist.

Flexor Tenosynovial Fistula as a Complication after Endoscopic Trigger Finger Release: A Case Report.

OBJECTIVE: We report a rare case of flexor tenosynovial fistula secondary to endoscopic release of the A1 pulley for treatment of trigger finger. CASE PRESENTATION: A 72-year-old woman underwent endoscopic release of the A1 pulleys of her left ring and right middle fingers. Nine days after surgery, the wound at the base of the proximal phalanx of the ring finger (distal portal) remained open and a clear liquid discharge was seen. The volume of discharge increased with active finger motion. However, there was no evidence of infection. The patient was diagnosed with tenosynovial fistula as a complication of endoscopic release of the A1 pulley. At day 30, the fistula and drainage persisted and the condition was managed by surgical excision of the fistula and primary closure. The wound then healed completely. CONCLUSION: Our report alerts hand surgeons to the potential development of flexor tenosynovial fistula as a very rare complication following endoscopic release of the A1 pulley for the treatment of trigger finger.

Multiple pilonidal sinuses of both hands in a dog groomer: A case report.

OBJECTIVE: Pilonidal sinus of the hand is an occupational hazard for barbers, cow milkers, sheep shearers and dog groomers. Here, we report on a dog groomer who had four pilonidal sinuses. CASE PRESENTATION: A 49-year-old woman working as a dog groomer complained of multiple non-erythematous and fluctuant nodules on both hands, associated with pain, which had been identified five years previously. On the skin of her right hand, three nodules were observed on the volar (diameter: 1.5 cm) and medial (diameter: 1.4 cm) sides of fifth metacarpophalangeal joint and the volar aspect of the distal phalanx of the small finger (diameter: 0.7 cm). On the left hand, a 2-cm diameter nodule was identified on the volar side of the fifth metacarpophalangeal joint region. The nodules were excised surgically. A 5-mm long hair was removed from one nodule. Histopathology confirmed pilonidal sinus, treated by excision. One month postoperatively, the wound had healed uneventfully. CONCLUSION: When nodules are found in dog groomers, clinicians should consider the possibility of pilonidal sinus disease.

Tremor Induced by Focal Peripheral Nerve Entrapment: A Case Series.

Little is known about tremors caused by peripheral nerve entrapment. We report two cases of tremors caused by peripheral nerve compressions. Two patients presented with intentional tremors combined with peripheral nerve compression symptoms on their affected hand. Based on the clinical findings and evaluations, the first patient was diagnosed with double-crush compression of the ulnar nerve at the cubital tunnel and Guyon canal, and the second patient was diagnosed with lacertus syndrome. The first patient underwent surgical release of the cubital tunnel and Guyon canal in two stages. The second patient underwent release of the lacertus fibrosus. At the 1-month follow-up after surgery, the tremors had completely resolved, and neurological symptoms improved. Peripheral nerve entrapment should be considered a potential cause of tremors in patients with tremors combined with symptoms of peripheral neuropathy. Surgical release can be curative.

The prevalence of double- and multiple crush syndromes in patients surgically treated for peripheral nerve compression in the upper limb.

OBJECTIVE: The double crush syndrome describes a condition characterized by multifocal entrapment of a nerve. In the upper limb, the high prevalence of carpal tunnel syndrome makes it a common diagnosis of assumption in the setting of median neuropathy. More proximal compressions may tend to be overlooked, under-diagnosed and under-treated in the population. This study aims to map the prevalence of peripheral upper limb nerve compressions among patients undergoing peripheral nerve decompression. METHODS: A prospective case series was conducted on 183 patients undergoing peripheral nerve decompression in a private hand surgery clinic. Level(s) of nerve compression in the median, ulnar and radial nerves were determined by history and physical examination. The prevalence of each nerve compression syndrome or combination of syndromes was analyzed. RESULTS: A total of 320 upper limbs in 183 patients were analyzed. A double crush of the median nerve at the levels of the lacertus fibrosus and carpal tunnel was identified in 78% of upper limbs with median neuropathy, whereas isolated lacertus syndrome and carpal tunnel syndrome were present in only 5% and 17% of affected limbs respectively. Cubital tunnel syndrome affected 12.5% of upper limbs, and 80% of these had concomitant lacertus and carpal tunnel syndromes, compared to only 7.5% with isolated cubital tunnel syndrome. CONCLUSION: A high prevalence should prompt clinicians towards more routine assessment for double crush syndrome to avoid misdiagnosis, inadequate treatment, recurrence, and revision surgeries.

Practical tips are presented, broken down into the preoperative, operative, and postoperative phases. Surgeons who commit to improving their patient experience will enjoy superior outcomes, patient loyalty, more fulfillment, and a rejuvenated sense of purpose.

Decreasing the pain of finger block injection: level II evidence.

BACKGROUND: There is level II evidence that volunteers prefer the single subcutaneous injection in the midline of the proximal phalanx with lidocaine and epinephrine (SIMPLE) finger block over the classic two dorsal injection block technique. The purpose of this study was to possibly further decrease the pain of digital block injection by examining the effect of the duration of injection on the pain felt by volunteers receiving the SIMPLE block at two different injection rates. METHODS: Forty healthy blinded volunteers were injected 2 mL of lidocaine 1 % and epinephrine 1/100,000 in the digital palmar crease of both long fingers, one at a time. Two different rates of injection were used: 8 and 60 s. Pain scores were measured using a visual analogue scale and the volunteers were asked which of injection techniques they preferred. RESULTS: The visual analogue scale results revealed less pain with the slow injection (p < 0.001). Thirty three out of 40 volunteers preferred the slow injection rate. No difference could be attributed to sex of participants or to the first hand injected. CONCLUSION: Blinded volunteers preferred digital blocks injected over 60 s to the more rapid 8 s. Decreasing the pain of injection only takes a minute of our valuable time for finger blocks.

Wound healing assessment: does the ideal methodology for a research setting exist?

INTRODUCTION: Studies on dressings frequently measure wound healing to demonstrate performance. Knowledge of existing methodologies available for wound healing assessment, including their advantages and limitations, is paramount when evaluating the literature on dressings. METHODOLOGY: Medline and Cochrane databases were searched for wound healing assessment methodologies used in research or in clinical practice. RESULTS: Twenty-nine methodologies were identified and classified into 8 categories: scales (n = 4), one-dimensional measurements (n = 2), area measurements (n = 4), volume measurements (n = 6), 3-dimensional wound reproduction systems (n = 5), methodologies based on wound physical characteristics (n = 3), rates and surrogates end point calculated from variation in wound dimensions (n = 4), and time to wound healing (n = 1). The main problems encountered during wound healing assessment include the following: boundary definition, assessor's contact with the wound, irregular wound shape, and difficulty in evaluating early healing. CONCLUSION: At this time, an ideal methodology does not exist. Research in this area is lacking and should be the focus in wound healing evaluation.

Recent Canadian plastic surgery graduates: are they prepared for the real world?

BACKGROUND: The purpose of this study was to evaluate the correlation between plastic surgery education received through residency in Canadian programs and perceived preparedness for independent clinical practice among recently graduated plastic surgeons. METHODS: All practicing plastic surgeons having graduated from a Canadian program between 1996 and 2006 were surveyed. An itemized Web-based questionnaire was designed and distributed by e-mail with the assistance of all program directors. RESULTS: Eighty (52 percent) of the 155 recent graduates from Canadian plastic surgery programs with valid contact information responded to the survey. The majority of respondents were satisfied with most aspects of their training. Only 22 percent of respondents had done part of their training in a foreign center, but all of them agreed that it was beneficial to their training. Clinical research was encouraged in 92 percent of the respondents' programs, but dedicated time was only allocated in 29 percent of these. At the beginning of their practice, the majority of respondents felt comfortable or very comfortable in all subspecialties with the exception of pediatric plastic surgery and ancillary procedures. CONCLUSIONS: The authors' results describe the tendencies in type and duration of the training that Canadian graduates had over the last 10 years. The majority of respondents were satisfied with most aspects of their residency programs and felt comfortable practicing different subspecialties early in their careers. Expectations during residency and the resources made available to meet these expectations are also revealed. This study will help improve residency programs by identifying existing gaps in the preparedness of surgeons.

Esophageal stricture and metaplasia following abdominoplasty.

Numerous complications have been reported following abdominoplasty. In this report, the case of a 48-year-old woman who developed an esophageal stricture, and subsequently Barrett's esophagus, secondary to increased intra-abdominal pressure following abdominoplasty is presented.

Prevention of surgical site infection and appropriateness of antibiotic prescribing habits in plastic surgery.

OBJECTIVES: The use of antimicrobial prophylaxis against surgical site infection (SSI) is widespread in plastic surgery, while results from prospective randomised controlled trials in guiding antibiotic use are lacking. The purpose of this study was to identify the incidence and risk factors for SSI in plastic surgery, and to evaluate the appropriateness of prophylactic antibiotic prescribing habits in a tertiary university centre. METHODS: A retrospective chart review was conducted over a 6-month period. Co-morbidities, types of procedure, prophylactic antimicrobial administration, SSI rates, and clinical outcomes were evaluated. RESULTS: The incidence of SSI was 9.3% for 335 procedures. The cumulative incidence of SSI for breast surgery (n=80) was 16.3%, with a 78.8% prescription rate. For head and neck procedures (n=68), the incidence of SSI was 10.3%, with 80.9% of patients receiving antibiotic prophylaxis. For hand and upper limb procedures (n=170), 70.6% of patients received antimicrobial prophylaxis, with a 4.7% SSI incidence. According to category A prophylaxis guidelines published in the plastic surgery literature, over prescribing was identified in 27.5% of breast, 61.8% of head and neck, and 19.4% of hand and upper limb procedures. CONCLUSIONS: This is the first study evaluating appropriateness of antimicrobial prophylaxis use by plastic surgeons. Despite widespread use of prophylactic antibiotics, significant SSI rates were still present and frequently responsible for re-hospitalisations and re-interventions. The appropriateness of administration and indications for perioperative prophylactic antibiotic use must be evaluated.

Heparin-induced thrombocytopenia syndrome as a cause of flap failure: a report of two cases.

BACKGROUND: Flap failure is a major complication in reconstructive plastic surgery. One of the most frequent etiologies of flap failure is venous thrombosis. However, infrequent causes also need to be explored, especially when faced with recurrent thrombosis. Heparin is frequently used in the prevention of venous thrombosis; however, the use of the medication itself may cause a serious thromboembolic state via an immune-related pathophysiological process. This adverse reaction to heparin may be life threatening. CASE PRESENTATION: We present two cases, one pedicled and one free flap, with venous congestion concomitant to heparin-induced thrombocytopenia syndrome, in conjunction with severe life-threatening sequelae. CONCLUSIONS: Heparin-induced thrombocytopenia syndrome can be the cause of postoperative venous congestion. It is necessary to be alert for this syndrome in the presence of recurrent unexplained venous thrombosis or thrombocytopenia in patients receiving anticoagulation therapy.

Outcomes in the management of sternal dehiscence by plastic surgery: a ten-year review in one university center.

PURPOSE: Infection rates following median sternotomy vary between 0.2% and 10%. These cases are associated with morbidity and mortality rates between 10% and 25% and 5% and 20%, respectively. The purpose of this study was to evaluate patient outcomes following plastic surgery correction of sternotomy dehiscence (SD). METHODS: All patients operated on for an SD following coronary artery bypass graft surgery (CABG), between 1995 and 2005, with 1 or more flaps, were included. RESULTS: Eighty cases were identified over a 10-year period. The mean age was 64 (+/-9.1) years. Two or more procedures were required in 17.5% of patients, and the mortality rate within 30 days was 12.5%. Significant variability was revealed between the cumulative mortality rates of plastic surgeons, from 0.0% to 50.0%. Multiple associations were identified for poor outcome, including chronic renal insufficiency and early mortality, and obesity with risk of reintervention. CONCLUSION: Although patients who undergo surgical correction of a deep sternal infection usually tolerate their intervention well, the mortality within 30 days remains high. This study has identified several factors explaining morbidity and mortality in this patient population.

Preliminary evaluation of infraclavicular catheters inserted using ultrasound guidance: through-the-catheter anesthesia is not inferior to through-the-needle blocks.

BACKGROUND AND OBJECTIVES: This prospective study compared the initial block quality and surgical anesthesia rates of ultrasound-guided infraclavicular blocks with local-anesthetic injected through a catheter versus through a needle. We hypothesized that positioning of the catheter immediately posterior to the axillary artery would produce through-the-catheter (TTC) anesthesia with rates of complete block not inferior to through-the-needle (TTN) injection. METHODS: Eighty patients undergoing hand or forearm surgery extensive enough to require regional anesthesia were randomized into 2 groups of 40. In group TTN, local anesthetic was deposited posterior, lateral, and medial to the axillary artery using as few injections as necessary. In group TTC, a 20-gauge, multiorifice catheter was positioned between the posterior wall of the axillary artery and the posterior cord of the brachial plexus. All blocks were performed by use of ultrasound visualization with a 6-MHz to 10-MHz 38-mm linear probe. Local-anesthetic solution consisted of 0.5 mL/kg lidocaine 2% with epinephrine. Sensory and motor blocks, as well as supplementation rates, were evaluated for the musculocutaneous, median, radial, and ulnar nerves. RESULTS: Complete sensory block of all nerve territories was achieved in 92% of patients in group TTN and 90% in group TTC (P = .51). In group TTN, 90% of patients had satisfactory anesthesia for surgery (no discomfort and no need for anesthetic supplementation of any type) compared with 92% in group TTC (P = .51). CONCLUSION: Ultrasound-guided TTC infraclavicular block produced perioperative anesthesia that was not inferior to a TTN technique.

Biomechanical evaluation of the ligamentous stabilizers of the scaphoid and lunate: part III.

PURPOSE: This study continued our previous investigations of the ligaments stabilizing the scaphoid and lunate in which we examined the scapholunate interosseous ligament, the radioscaphocapitate, and the scaphotrapezial ligament. In this current study, we examined the effects of sectioning the dorsal radiocarpal ligament, dorsal intercarpal ligament, scapholunate interosseous ligament, radioscaphocapitate, and scaphotrapezial ligaments. In the current study, the scapholunate interosseous ligament, radioscaphocapitate, and scaphotrapezial ligaments were sectioned in a different order than performed previously. METHODS: Three sets of 8 cadaver wrists were tested in a wrist joint motion simulator. In each set of wrists, only 3 of the 5 ligaments were cut in specific sequences. Each wrist was moved in continuous cycles of flexion-extension and radial-ulnar deviation. Kinematic data for the scaphoid and lunate were recorded for each wrist in the intact state, after the 3 ligaments were sectioned in various sequences and after the wrist was moved through 1,000 cycles of motion. RESULTS: Dividing the dorsal intercarpal or scaphotrapezial ligaments did not alter the motion of the scaphoid or lunate. Dividing the dorsal radiocarpal ligament alone caused a slight statistical increase in lunate radial deviation. Dividing the scapholunate interosseous ligament after first dividing the dorsal intercarpal, dorsal radiocarpal, or scaphotrapezial ligaments caused large increases in scaphoid flexion and lunate extension. CONCLUSIONS: Based on these findings, we concluded that the scapholunate interosseous ligament is the primary stabilizer and that the other ligaments are secondary stabilizers of the scapholunate articulation. Dividing the dorsal radiocarpal, dorsal intercarpal, or scaphotrapezial ligaments after cutting the scapholunate interosseous ligament produces further changes in scapholunate instability or results in changes in the kinematics for a larger portion of the wrist motion cycle.
