Decompression of the superficial peroneal nerve: clinical outcomes and anatomical study.

OBJECTIVE The authors of this study sought to determine the outcomes of patients undergoing superficial peroneal nerve (SPN) release to treat lower-extremity pain and describe consistent anatomical landmarks to direct surgical planning. METHODS This retrospective cohort study examined 54 patients with pain in the SPN distribution who were treated with decompression between 2011 and 2014. Patients rated pain and the effect of pain on quality of life (QOL) on the visual analog scale (VAS) from 0 to 10. Scores were then converted to percentages. Linear regression analysis was performed to assess the impact of the preoperative effect of pain on QOL, age, body mass index (BMI), and preoperative duration of pain on the postoperative effect of pain on QOL. Measurements were made intraoperatively in 13 patients to determine the landmarks for identifying the SPN. RESULTS A higher BMI was a negative predictor for improvement in the effect of pain on QOL. A decrease in pain compared with the initial level of pain suggested a nonlinear relationship between these variables. A minority of patients (7 of 16) with a preoperative pain VAS score ≤ 60 reported less pain after surgery. A large majority (30 of 36 patients) of those with a preoperative pain VAS score > 60 reported improvement. Intraoperative measurements demonstrated that the SPN was consistently found to be 5 ± 1.1, 5 ± 1.1, and 6 ± 1.2 cm lateral to the tibia at 10, 15, and 20 cm proximal to the lateral malleolus, respectively. CONCLUSIONS A majority of patients with a preoperative pain VAS score > 60 showed a decrease in postoperative pain. A higher BMI was associated with less improvement in the effect of pain on QOL. This information can be useful when counseling patients on treatment options. Based on the intraoperative data, the authors found that the SPN can be located at reliable points in reference to the tibia and lateral malleolus.

Unnecessary Emergency Transfers for Evaluation by a Plastic Surgeon: A Burden to Patients and the Health Care System.

BACKGROUND: Plastic surgeons are frequently consulted for hand and facial injuries, and patients are often transferred to trauma centers for evaluation of these problems. The authors sought to identify the frequency and impact of "unnecessary" transfers for emergency evaluation by a plastic surgeon at a Level I trauma center. METHODS: The authors reviewed more than 32,000 consecutive emergency department encounters at their institution between April of 2009 and April of 2013 and found 1181 patients transferred for evaluation by plastic surgery. Using a retrospective chart review, necessity of transfer was determined based on the intervention performed at the authors' institution and the availability of resources at the transferring site. RESULTS: Of all the patients referred for "emergency" evaluation, 860 (74.1 percent) were unnecessary. Transfers for hand-related issues were more likely to be coded as unnecessary compared with referrals for facial trauma and infection (76 percent versus 66 percent; p < 0.001). The average time from referral to discharge from the emergency department was 412 minutes. The expense for these unnecessary transfers exceeded $4.6 million. CONCLUSIONS: This is the first intervention-based study evaluating the impact of unnecessary transfer for evaluation of hand and facial emergencies. Using a framework based on objective outcomes, the authors found that fewer than one-third of patients required emergent transfer for evaluation by a plastic surgeon, and almost half did not receive an intervention following transfer. Based on patient time and financial expenses for these unnecessary evaluations, improvements could be made in both quality and cost of care by limiting inappropriate emergency department referrals.

Intraneural Median Nerve Anatomy and Implications for Treating Mixed Median Nerve Injury in the Hand.

Background: Nerve transfers have resulted in increased interest in the microanatomy of peripheral nerves. Herein, we expand our understanding of the internal anatomy of the digital nerve to the ulnar index and long fingers, the radial long and ring fingers, and the nerves to the second and third web spaces. Methods: The median nerve was dissected from the digital nerves to the antecubital fossa in 14 fresh upper extremities. The distance of proximal internal neurolysis of the fascicles to the second and third web space and proper digital nerves was measured relative to the radial styloid. Plexi encountered during proximal lysis were noted. Results: Digital nerves to the ulnar index and radial long fingers were lysed 2.4 ± 0.5 cm (mean ± SD), and digital nerves to the ulnar long and the radial ring fingers were lysed 3.0 ± 0.6 cm distal to the radial styloid. Fascicles to the third web space were lysed to the takeoff of the anterior interosseous nerve, 21.1 ± 1.4 cm. Plexus groupings were encountered at 4.5 ± 1.6 cm, 8.3 ± 1.2, cm and 16.1 ± 1.9 cm proximal to radial styloid. The fascicles to the second web space were lysed to 5.0 ± 1.2 cm proximal to radial styloid where a plexus grouping was encountered. Another plexus group was found at 3.3 ± 1.3 cm. Conclusions: We demonstrate that extended internal neurolysis of second web space, along with the digital nerves, is technically and clinically feasible. This technique can be used to treat mixed median nerve injury in the hand and wrist.

Evidence for safe tourniquet use in 500 consecutive upper extremity procedures.

BACKGROUND: Although pneumatic tourniquets are widely used in upper extremity surgery, further evidence is needed to support their safe use. Excessive pressure and prolonged ischemic time can cause soft-tissue injury. The purpose of this study was to determine the safety of tourniquet use in a yearlong, consecutive series of patients. METHODS: A retrospective review of all patients who underwent upper extremity surgery by two board-certified hand surgeons over a 1-year period was performed. Demographic variables, comorbidities, and complications were noted along with tourniquet parameters, including application site, ischemic pressure, and time. RESULTS: A total 505 patients were included in the study because a tourniquet was used during their operation. Patients ranged in age from 3 months to 90 years old (mean 40.1 years). More than half of the population was overweight (mean body mass index (BMI) 27.1), and 77.1 % of adults had at least one cardiac risk factor. No immediate or delayed tourniquet-related injuries were identified. The average operative time was 35.9 min, with an average tourniquet time of 33.1 min. Tourniquet inflation pressure of 250 or 225 mmHg was utilized in 78 and 21 % of adult patients, respectively; no patients had a pressure setting exceeding 275 mmHg. CONCLUSION: In this series of more than 500 operations, there were no immediate or delayed tourniquet-related events using parameters determined perioperatively by the attending surgeon. Tourniquet pressures of 250 mmHg or less in adult patients with less than 2 h of ischemic time appear to be safe, even in the elderly and patients with multiple medical comorbidities.

Finesse in forehead and brow rejuvenation: modern concepts, including endoscopic methods.

BACKGROUND: The brow and forehead are essential elements of the facial aesthetic architecture. Although frequently overlooked in youth, signs of facial aging are often most noticeable in the upper third of the face. Ptosis and loss of contour in the brows, along with temporal volume loss, sagging of periorbital tissue, and rhytides in the forehead, are common presenting complaints for aesthetic surgery. Although use of nonsurgical procedures (e.g., neuromodulators) has become very common practice, knowledge of surgical anatomy and interventions for brow and forehead rejuvenation are critical for a plastic surgeon. The earliest descriptions of brow-lift procedures are nearly a century old. Techniques have evolved significantly, to the point that patients may now return to work within 1 week of surgery, with minimal or no stigmata from an operation. METHODS: The literature and a series of cases from the senior surgeon (P.K.S.) were reviewed. RESULTS: A minimally invasive approach with an endoscope for dissection and repositioning of the brow was used in all patients. The authors have found that permanent suture fixation with cortical tunnels can produce an excellent, long-lasting aesthetic result for not only the forehead and brow but also the lateral periorbital and temporal regions. CONCLUSIONS: Although each operation is tailored to the patient's individual anatomy, the authors' approach to the endoscopic procedure is described in this article, along with a review of anatomical and surgical considerations. Finally, several patients provide demonstrative results from the senior surgeon's series of 546 patients.

Direct radial to ulnar nerve transfer to restore intrinsic muscle function in combined proximal median and ulnar nerve injury: case report and surgical technique.

A distal median to ulnar nerve transfer for timely restoration of critical intrinsic muscle function is possible in isolated ulnar nerve injuries but not for combined ulnar and median nerve injuries. We used a distal nerve transfer to restore ulnar intrinsic function in the case of a proximal combined median and ulnar nerve injury. Transfer of the nonessential radial nerve branches to the abductor pollicis longus, extensor pollicis brevis, and extensor indicis proprius to the motor branch of the ulnar nerve was performed in a direct end-to-end fashion via an interosseous tunnel. This method safely and effectively restored intrinsic function before terminal muscle degeneration.

Piezoelectric technology for pediatric autologous cranioplasty.

Objective : Pediatric patients with skull defects larger than available sources for splitting bicortical bone have limited options for autogenous cortical bone cranioplasty. Piezoelectric instruments allow donor bone to be chosen based on the best possible contour rather than the presence of bicortical bone. We present the use of piezoelectric technology to split thin unicortical calvarium for autogenous cranioplasty in a series of pediatric patients. Design : Retrospective review of a series of pediatric patients requiring reconstruction for skull defects. Patients/Intervention : Our series included a 2-year-old with a parietal skull tumor and resultant 3 × 3-cm defect after craniectomy, a 2-year-old with a 3 × 3-cm defect after excision of an occipital skull tumor, a 10-year-old with a 4 × 5-cm skull defect after excision of an occipital skull tumor, and a 13-year-old who suffered a gunshot to the forehead with a 12 × 7-cm frontal skull defect. We used a piezoelectric saw to precisely and safely split unicortical and bicortical cranium that ranged from 1 to 3 mm in thickness. The inner layer was used to reconstruct the donor site; whereas, the outer layer was used for the craniectomy defect. Conclusion : The piezoelectric saw allows unicortical bone to be split and used for cortical bone cranioplasty. This technology allows choice of donor site based on the best contour rather than the presence of bicortical bone. This technique expands the possibilities of autogenous cranioplasty and enables primary repair of cranial defects that would otherwise require secondary cranioplasty with remote donor sites, foreign materials, or unstable particulate cranioplasty.

Disparities in the provision of sexually transmitted disease and pregnancy testing and prophylaxis for sexually assaulted women in Rhode Island emergency departments.

OBJECTIVES: To determine how often sexually assaulted adult female emergency department (ED) patients are being offered testing and prophylaxis for sexually transmitted diseases (STDs) and pregnancy and identify factors associated with the offering of tests and prophylaxis. METHODS: This is a retrospective study of ED visits for adult female sexual assault in all Rhode Island EDs from January 1995 through June 2001. The percentage of patients offered testing and prophylaxis was calculated. Multivariable logistic regression was used to identify factors related to testing and prophylaxis use for women sustaining an anal/vaginal assault. RESULTS: Of the 780 patients, 78.2% sustained anal/vaginal penetration, 5.0% genital touching only, and 3.7% oral sex only, and 13.1% did not know what happened to them. Of those women anal/vaginally assaulted, 83.8% were offered chlamydia/gonorrhea testing, 69.4% syphilis testing, 82.9% pregnancy testing, 77.0% chlamydia/gonorrhea prophylaxis, 47.6% emergency contraception, and 19.2% HIV prophylaxis. In multivariable logistic regression models, patients evaluated at the state's women's hospital instead of academic or community hospitals and those who sustained anal/vaginal assault instead of other assaults had a greater odds of being offered testing and prophylaxis. In some cases, older women were offered testing and prophylaxis less often than younger women. CONCLUSIONS: Testing and prophylaxis for chlamydia/gonorrhea were used much more often than prophylaxis for emergency contraception and HIV, even for patients who were anal/vaginally assaulted. Disparities in testing and prophylaxis exist by type of hospital and, in some cases, by age. Educational campaigns should be instituted to ensure that all women receive adequate testing and prophylaxis commensurate with the exposure they sustained from a sexual assault.
