RESUMEN

Purpose: Understanding the variables that influence success in digital replant surgery is essential to guide clinical decision-making and to counsel patients. The purpose of this study was to determine the replant success rate and identify predictors of success at our tertiary care centre. Methods: This was a single centre, retrospective cohort study of consecutive patients who underwent digital replantation from January 2000 to September 2018. Adult patients with flexor zone I to III amputations were included. Patient demographics, comorbidities, injury pattern, operative data, and post-operative care were reviewed. The primary outcome was survival of the replanted digit at discharge. Results: A total of 146 patients met inclusion criteria. Of these, 100 had single-digit replants and 46 underwent multi-digit replants for a total of 220 digits. The success rate was 71%. Predictors of success included sharp mechanism of injury (P < .01), incomplete amputation (P < .01), amputation proximal to zone I flexor level (P = .02), post-operative acetylsalicylic acid use (P < .01), absence of leech use (P = .05), and absence of operative re-exploration (P < .01). Daytime replants had similar outcome compared to nighttime replants despite having increased ischemia time (7.9 ± 3.9 hours vs 6.8 ± 2.6 hours, P = .02). However, daytime operative time (7.8 ± 3.7 hours) was significantly shorter than nighttime replant time (9.6 ± 5.9 hours, P = .01). Conclusion: Sharp amputation, intact venous drainage, proximal amputation, and acetylsalicylic acid use were associated with replant survival and are factors to consider when managing patients for digital replantation. Leech therapy and operative re-exploration were associated with poor outcome. Nighttime replants required significantly longer operative time than daytime replants despite similar survival outcome.

Objectif: Il est essentiel de comprendre les variables qui influent sur la réussite de la réimplantation digitale par voie chirurgicale pour orienter les décisions et conseiller les patients. La présente étude visait à déterminer le taux de réussite des réimplantations et à déterminer les prédicteurs de réussite au centre de soins tertiaires des chercheurs. Méthodologie: Cette étude de cohorte monocentrique et rétrospective portait sur des patients consécutifs qui avaient subi une réimplantation chirurgicale entre janvier 2000 et septembre 2018. Les patients adultes ayant subi des amputations des zones I à III des fléchisseurs ont été retenus. Les chercheurs ont évalué les caractéristiques démographiques des patients, leurs maladies associées, leur type de blessures, les données opératoires et leurs soins postopératoires. La survie du doigt réimplanté au congé était le résultat primaire. Résultats: Au total, 146 patients ont respecté les critères d'inclusion. De ce nombre, 100 avaient fait réimplanter un seul doigt et 46, plusieurs doigts, pour un total de 220 doigts. Le taux de réussite s'élevait à 71%. Les prédicteurs de réussite incluaient un mécanisme franc de blessure (p<0,01), une amputation incomplète (p<0,01), une amputation proximale au fléchisseur de la zone I (p=0,02), la prise d'acide acétylsalicylique après l'opération (p<0,01), la non-utilisation de sangsues (p=0,05) et l'absence de réexploration opératoire (p<0,01). Les réimplantations effectuées le jour donnaient des résultats semblables à celles qui étaient effectuées la nuit, malgré une durée d'ischémie plus longue (7,9±3,9 h par rapport à 6,8±2,6 h, p=0,02). Cependant, les opérations exécutées le jour (7,8±3,7 h) était beaucoup plus courtes que celles effectuées la nuit (9,6±5,9 h, p=0,01). Conclusion: Une amputation franche, un drainage veineux intact, une amputation proximale et la prise d'acide acétylsalicylique étaient liés à la survie de la réimplantation et représentent des facteurs à considérer dans la prise en charge des patients qui doivent subir une réimplantation digitale. La thérapie par les sangsues et la réexploration opératoire étaient associées à un mauvais pronostic clinique. Les réimplantations opératoires effectuées la nuit étaient beaucoup plus longues que celles effectuées le jour, malgré un taux de survie semblable.

RESUMEN

SUMMARY: Brachial plexopathy after conservative therapy or surgical treatment of clavicular fractures is an uncommon, yet serious complication that is associated with compression of the brachial plexus or the subclavian artery and vein because they traverse through the thoracic outlet. Surgical decompression of the brachial plexus is the recommended treatment if this condition is to occur. Although there are multiple reports of these cases in the literature, at present, there are no clear guidelines for their management. We are highlighting an institutional management algorithm, illustrated by a small retrospective case series, that uses a multidisciplinary approach in an effort to minimize complications associated with the management of clavicle nonunion.

RESUMEN

OBJECTIVE: The purpose of this systematic review and meta-analysis was to determine the effect of nerve transfer surgery for brachial plexus injury (BPI) on patient-reported outcomes. LITERATURE SURVEY: MEDLINE, EMBASE, and CINAHL were searched and screened in duplicate for relevant studies on September 25, 2019 and repeated June 24, 2020. METHODOLOGY: The patient population included male and female patients who received nerve transfer surgery for BPI. Further inclusion criteria were: (1) all levels of evidence; (2) published in English; (3) conducted in humans; and (4) report of patient-reported outcome. Two reviewers independently abstracted data regarding injury type, surgical technique, surgical timing, follow-up duration, strength, and patient-reported outcome measures. Quality was assessed in duplicate using the Methodological Index for Non-Randomized Studies criteria. SYNTHESIS: Twenty-one studies involving 464 participants were included in analyses. The mean age ± SD was 32.4 ± 1.8 (range: 5-77) and 89.2% of included participants were male. The mean time to surgery was 5.6 ± 0.6 months and the mean follow-up time was 48.1 ± 8.4 months. The most used patient-reported outcome was the Disabilities of Arm, Shoulder and Hand (DASH), where scores variably improved postoperatively, although the degree of disability remained high. Return to work was reported in five studies, with 66.0% of participants returning to work. Patient satisfaction was assessed in four studies with an overall satisfaction proportion of 64.0%. Pain was assessed in 12 studies using various measures. In studies reporting pain intensity postoperatively, 29.3% of patients were "pain-free" or had "no pain." CONCLUSIONS: Patient-reported outcomes following nerve transfer for BPI are infrequently reported in the literature. Although patient-reported outcomes demonstrate variable postoperative improvement, there is evidence of ongoing limitations and postoperative DASH scores report a high degree of ongoing disability. Future studies with greater reporting as well as validation of patient-reported outcomes within BPI are warranted.

RESUMEN

OBJECTIVE: To investigate which tests of hand sensibility correlate with functional outcomes in patients with upper limb traumatic nerve injuries and to assess if composite scales of sensibility correlate with functions. DATA SOURCES: MEDLINE, Embase, and Cochrane Central Register of Controlled Trials were searched in May 2020, with a supplementary search in July 2020. Reference lists of the included publications were hand searched. STUDY SELECTION: Database search found 2437 records. Eligible studies reported on inferential association between sensibility tests and functions pertaining to adults after upper limb nerve repair. Two reviewers independently assessed eligibility. Fifteen publications were included. DATA EXTRACTION: Extracted data contain patient characteristics, surgical procedure, follow-up duration, sensibility tests, and functional assessments. Two reviewers independently assessed data quality. DATA SYNTHESIS: Fifteen publications involving 849 patients were reviewed. All publications reported on median and/or ulnar nerve injuries. Monofilament tests correlated with Short-Form Health Survey (r=0.548, P<.05), pick-up test (r=0.45, P<.05), and function domain of Patient-Rated Wrist and Hand Evaluation Questionnaire (PRWHE) (r=0.58, P<.05). The 8 studies of static and moving 2-point discrimination provided conflicting correlations with activities of daily living (ADL) and/or the pick-up test. Data for area localization and object/shape identification were equivocal as well. No data were found for Ten test and vibration tests. Rosén score sensory domain correlated with ADL (r=0.59; 95% confidence interval [CI], 0.41-0.72) and PRWHE function domain (r=-0.56, P<.05). Medical Research Council sensory scale was related to pick-up test; return to work status; and Disabilities of the Arm, Shoulder, and Hand questionnaire. CONCLUSIONS: Monofilament tests allow practitioners to gather sensibility data meaningful to patients' overall recovery of functions after upper limb nerve trauma. For 2-point discrimination and other sensibility tests, practitioners should be aware that improvement in test performance does not necessarily translate to improved hand function. Findings from the composite scales indicate that hand sensibility, in general, is related to functions. Future research on other common sensibility tests is recommended to explore how the test relates to patients' functions.

RESUMEN

Nerve transfer surgery for patients with nerve and spinal cord injuries can result in dramatic functional improvements. As a result, interdisciplinary complex nerve injury programs (CNIPs) have been established in many Canadian centers, providing electrodiagnostic and surgical consultations in a single encounter. We sought to determine which allied health care services are included in Canadian CNIPs, at the 3rd Annual Canadian Peripheral Nerve Symposium. Twenty CNIPs responded to a brief survey and reported access as follows: occupational therapy = 60%, physiotherapy = 40%, social work = 20%, and mental health = 10%. Access to allied health services is variable in CNIPs across Canada, possibly resulting in heterogeneity in patient care.

RESUMEN

"Ten Test" (TT) is a bedside measure of discriminative sensation, whereby the magnitude of abnormal sensation to moving light touch is normalized to an area of normal sensation on an 11-point Likert scale (0-10). The purposes of this study were to determine reliability parameters of the TT in a cohort of patients presenting to a hand trauma clinic with subjectively altered sensation post-injury and to compare the reliability of TT to that of the Weinstein Enhanced Sensory Test (WEST). Study participants (n = 29, mean age = 37 ± 12) comprised patients presenting to an outpatient hand trauma clinic with recent hand trauma and self reported abnormal sensation. Participants underwent TT and WEST by two separate raters on the same day. Interrater reliability, response stability and responsiveness of each test were determined by the intraclass correlation coefficient (ICC: 2, 1), standard error of measurement (SEM) with 95% confidence intervals (CI) and minimal detectable difference score, with 95% CI (MDD95), respectively. The TT displayed excellent interrater reliability (ICC = 0.95, 95% CI 0.89-0.97) compared to good reliability for WEST (ICC = 0.78, 95% CI 0.58-0.89). The range of true scores expected with 95% confidence based on the SEM (i.e. response stability), was ±1.1 for TT and ±1.1 for WEST. MDD95 scores reflecting test responsiveness were 1.5 and 1.6 for TT and WEST, respectively. The TT displayed excellent reliability parameters in this patient population. Reliability parameters were stronger for TT compared to WEST. These results provide support for the use of TT as a component of the sensory exam in hand trauma.

RESUMEN

In cases of median nerve injury alongside an unsalvageable ulnar nerve, a vascularized ulnar nerve graft to reconstruct the median nerve is a viable option. While restoration of median nerve sensation is consistently reported, recovery of significant motor function is less frequently observed. The authors report a case involving a previously healthy man who sustained upper arm segmental median and ulnar nerve injuries and, after failure of sural nerve grafts, was treated with a pedicled vascularized ulnar nerve graft to restore median nerve function. Long-term follow-up showed near full fist, with 12 kg of grip strength, key pinch with 1.5 kg of strength and protective sensation in the median nerve distribution. The present case demonstrates that pedicled ulnar vascularized nerve grafts can provide significant improvements to median nerve sensory and motor function in a heavily scarred environment.

Une greffe du nerf cubital vascularisé pour reconduire le nerf médian est une solution viable lorsque le nerf cubital ne peut pas être récupéré. La sensation du nerf médian est presque toujours rétablie, mais la fonction motrice significative l'est moins. Les auteurs présentent le cas d'un homme auparavant en santé qui a subi des traumatismes des nerfs médian et cubital du bras et, après le rejet des greffes du nerf saphène externe, a subi une greffe du nerf cubital pédiculé vascularisé pour rétablir la fonction du nerf médian. Au suivi à long terme, le poing était presque complet, la prise de force atteignait 12 kg, la pince sub-termino-latérale s'associait à une force de 1,5 kg et la distribution du nerf médian était liée à une sensation protectrice. Le présent cas démontre que des greffes du nerf cubital pédiculé vascularisé peuvent améliorer considérablement la fonction sensorielle et motrice du nerf médian très cicatrisé.

RESUMEN

Various techniques have been described for securing the nail plate back in its anatomic position after trauma or for reconstructive exposure. The figure-of-eight suture technique uses the paronychial folds and notches in the distal aspect of the nail plate to create both ventral and proximal forces to secure the nail plate under the eponychial fold. The transverse figure-of-eight suture prevents the nail from moving distally or dorsally. It is simple, secure, and easily taught to non-hand surgeons. This technique can also be used when the eponychium is damaged. It is a useful adjunct to the armamentarium of anyone treating finger-tip injuries.

RESUMEN

Due to concerns for increased complications, there is reluctance to use the ipsilateral pedicled TRAM for breast reconstruction in the presence of previous chest wall irradiation. This study will assess whether the ipsilateral pedicled TRAM is a safe and effective option when the pedicle is part of the irradiation field. Consecutive cases of ipsilateral pedicled TRAM flap procedures from 1997-2003 were reviewed. Patients with and without previous irradiation were compared on several vascular indicators. There were 123 and 124 patients in the irradiated and nonirradiated groups, respectively. These groups were demographically similar, except the nonirradiated group was significantly older. The irradiated group had a significantly higher rate of minor wound problems related to mastectomy flap healing (8.9% versus 1.6%). All other flap vascular complications were equivalent. The ipsilateral pedicled TRAM flap is a safe and effective option for breast reconstruction in an irradiated field in terms of the pedicle to the flap.
