RESUMEN

Macro-amputations are extremely serious traumas and represent one of the rare extreme emergencies in hand and upper limb surgery. Their rarity, especially in our developed countries, makes their treatment relatively unknown by surgical and anesthetic teams. However, the action plan to use during a macro-reimplantation, the decisive elements of pre- and post-operative management, and the key stages of the surgery, must be perfectly known, because they determine the success of a major reimplantation, for the limb survival and the future functional result. After a brief historical overview, the literature review proposed here provides an opportunity for an update on these formidable injuries and propose a treatment algorithm to guide the medical team in the management of these complex patients.

RESUMEN

Background. Performance-based outcome measures (PBOMs) are objective measures that assess physical capacity or performance in specific tasks or movements. Purpose. 1) to identify which PBOMs are most frequently reported to evaluate upper extremity (UE) function in pediatric rehabilitation 2) to determine the link between constructs of the ICF and meaningful concepts extracted from each identified PBOM. Methods. Pediatric UE PBOMs were searched in four databases. The selection of outcome measures included an initial title and abstract screening, followed by full-text review of the articles to be included based on identified selection criteria. Two reviewers were appointed to link the meaningful concepts identified in the outcome measures independently and a third reviewer was consulted in case of ambiguity to make a final decision. Findings. After the initial screening, 1786 full-text articles were reviewed, 1191 met the inclusion criteria, in which 77 outcome measures were identified and 32 were included in the linking process. From the included 32 outcome measures, 538 items were extracted and linked to the ICF. The most commonly cited measures included Assisting Hand Assessment, Jebsen-Taylor Hand Function Test, Melbourne Assessment of Unilateral Upper Limb. The Activity and Participation domain represented 364 codes followed by the Body Functions domain domain which represented 174 codes. Implications. A majority of the outcome measures identified were linked with the Mobility, Fine Hand Use of the ICF. Therefore, when selecting a PBOM, careful considerations need to be made regarding which concept of health is to be assessed.

RESUMEN

Deep burns sequelae involving the upper limb are challenging even for experienced surgeons, mainly because local reconstructive options and donor sites are often compromised. The use of free flaps for this type of reconstruction remains difficult due to the small recipient vessel diameter and tendency to vasospasm. Moreover, pediatric cases bring the challenge to another level. We present the case of a 13-year-old girl presenting major retractile sequelae of the upper left limb, including complete wrist immobilization combining wrist hyper-extension, ulnar deviation deformity, and a ulno-carpal dislocation. She was referred to our department where a two-stage reconstruction was performed using a pre-expanded free deep inferior epigastric artery perforator (DIEP) flap. The first surgery consisted of placing two kidney-shaped expanders in a subfascial plane in the hypogastric region. Four months later, after a bi-weekly expansion, an excision of the scar tissue, and the DIEP flap transfer were completed. At the 12-month follow-up evaluation, both aesthetic and functional results were satisfactory, with a good contour and regained mobility of the wrist.

RESUMEN

We designed a new method using hemi-longitudinal second metacarpal bone to reconstruct grade-3 hypoplastic thumbs. Seven patients were treated in two stages. In the first stage, the second metacarpal was split longitudinally and transferred to reconstruct the first metacarpal. In the second stage, opponensplasty was performed by transferring the FDS tendon. Bone union was achieved in all cases. All patients could oppose to their middle finger at least. They managed to do daily activities such as writing, eating, using smartphones and so on. This is a useful procedure to preserve a 5-digit hand with good function in treating grade-3 hypoplastic thumbs, with no harm to the foot and no need for vascular anastomosis. LEVEL OF EVIDENCE: IV.

RESUMEN

OBJECTIVES: There is growing evidence of cognitive impairment after traumatic peripheral lesions. The purpose of this study was to explore the association between cognitive function and traumatic upper-limb injury. We assessed difference in cognitive function between participants with and without upper-limb injury, and explored the association between cognitive function and certain variables in injured individuals: gender, age, body mass index (BMI), educational level, and occupation. We sought to identify the factors associated with cognitive function in injured subjects: time since injury, injury side, nerve injury, hand function, pain, and finger sensation. MATERIAL AND METHODS: A cross-sectional observational study was conducted, with 2 groups: observational group (with traumatic upper-limb injury) and control group (uninjured). The 2 groups were matched for age, gender, BMI, educational level and occupation. Short-term memory and executive functions were assessed using the Rey Auditory and Verbal Learning Test (RAVLT) and Stroop Color and Word Test (SCWT), respectively. RESULTS: 104 participants with traumatic upper-limb injury and 104 uninjured control subjects were included. There was a significant inter-group difference only in RAVLT (p < 0.01; Cohen d, of 0.38). Regression analysis demonstrated an association of pain on VAS (beta = -0.16, p < 0.01) and touch-test (beta = 1.09, p < 0.05) with total RAVLT score (short-term memory) in injured subjects (R2 = 0.19, F (2, 82) = 9.54, p < 0.001). CONCLUSION: Traumatic upper-limb injury can impact short-term memory, which should be kept in mind during rehabilitation.

RESUMEN

Although not as common as solitary lesions, multiple schwannomas do occur, even in single nerve lesions. We report a rare case of a 47-year-old female patient who presented with multiple schwannomas with inter-fascicular invasion in the ulnar nerve above the cubital tunnel. Preoperative MRI revealed a 10-cm multilobulated tubular mass along the ulnar nerve above the elbow joint. During excision under 4.5° loupe magnification, we separated three ovoid yellow-colored neurogenic tumors of different sizes, but there were still remaining lesions as it was difficult to completely separate lesions from the ulnar nerve due to the risk of iatrogenic nerve ulnar nerve injury. The operative wound was closed. Postoperative biopsy confirmed the diagnosis of the three schwannomas. During the follow-up, the patient recovered without neurological symptom or limitations in range of motion, and there were no neurological abnormalities. At 1year after surgery, small lesions remained in the most proximal part. However, the patient had no clinical symptoms and was satisfied with the surgical results. Although a long-term follow-up is necessary for this patient, we were able to obtain good clinical and radiological results.

RESUMEN

Upper limb spasticity following upper motor neuron lesion is a key cause of long-term disability in adults, causing functional loss, pain, and reduced quality of life. Surgical management is an under-utilized intervention, and little work has been performed to collate and evaluate the evidence for these interventions. We undertake the first, PRISMA-compliant systematic review synthesizing the evidence for surgical management of spasticity in adults. Three databases were searched using pre-specified search strings over a 20-year window (September 2001-2021). Only primary research papers featuring an entirely adult sample were included. Case reports were excluded. Quality assessment was performed using the Oxford Centre for Evidence-Based Medicine Scale and the Methodological Index for Non-Randomized Studies. We identified 19 eligible studies, all of which were poor quality. Significant benefit of surgery was identified in 15 of the 16 studies conducting significance testing. Detailed analysis of the surgical procedures used was prevented by poor reporting. Studies reported low rates of serious postoperative complication, and relatively high rates of postoperative deformity recurrence. Studies' approaches to patient assessment and management varied significantly, reflecting a lack of standardization in this field. This review suggests that higher-quality, more standardized evidence is required to demonstrate the safety and efficacy of these surgical procedures. Future work should focus on improved reporting of surgical procedures and development of consensus assessment tools focusing on assessment of patient functionality and quality of life.

RESUMEN

We compared the minute-by-minute muscle activity and oxygenation responses to a repetitive arm motion-induced fatiguing task between the sexes in order to address the literature gap on these time-dependent fatigue responses. Twenty-six (13 females) healthy adults performed a repetitive pointing task (RPT) with the arm moving forward/backward at shoulder height until reaching 8/10 (Borg CR10) for neck/shoulder perceived exertion (RPE). Neck/shoulder RPE, oxygenation and electromyography were recorded every minute and compared between first and second half of the task and between the sexes. Greater changes in oxygen supply and activation amplitude occurred during the second half of the task. Despite similar time to fatigue-terminal (p > 0.05), females showed greater anterior deltoid activation amplitude at all time points than males, and only the males showed increases in anterior and posterior deltoid activation amplitudes. In females, middle (ρ = -0.34, p = 0.04) and posterior (ρ = -0.44, p = 0.01) deltoid amplitudes were negatively correlated with perceived exertion during the first half of the task. Results suggest that reduced modulation of anterior deltoid activation amplitude in females may reflect a sub-optimal fatigue-mitigation mechanism compared with males and may help explain their greater susceptibility to neck/shoulder musculoskeletal disorders. Novelty: Despite similar fatigability and trapezius oxygenation, females showed greater deltoid activation throughout the task. Deltoid activation increased in males but not in females. The results support the important role of the deltoid in sex-specific neck/shoulder injury mechanisms.

RESUMEN

In addition to motor deficits, central nervous system disorders combine major alterations in the motor pattern with spasticity and over time, contractures. Their varied clinical presentation makes their assessment and the therapeutic strategy more complex. For these reasons, tendon transfers in this population will have more limited indications and above all, will have to be integrated into a complex surgical program combining other procedures such as tendon lengthening, selective neurotomies and joint stabilization. The surgical strategy is far from being obvious. When faced with clinical presentations having very different objectives-functional or comfort only-it is difficult at first sight to build a standardized surgical program. We therefore propose a method to evaluate these patients, thanks to a score (INOM) that integrates prognostic factors and parameters to be corrected surgically. Three components guide this program: a prognostic factor (proximal motor control of the shoulder and elbow), correction of abnormal limb postures and restoration of active elbow, wrist and finger extension. The surgical strategy can be constructed from the INOM score which establishes the priorities for care. Nerve blocks and botulinum toxin injections are essential tools for this analysis. They help distinguish between spasticity and contracture, and can unmask certain antagonistic muscles. A tendon transfer in this population will be just as effective by the function it restores as by the action it suppresses in a malpositioned limb. For each joint, we describe the indications for tendon transfers and their relative role among the techniques with which they must be combined.

RESUMEN

Neurogenic heterotopic ossifications (NHOs) are periarticular ectopic ossifications that frequently develop after a central nervous system injury, most often a traumatic one. They limit range of motion and cause pain, interfering with limb positioning and function, whether active or passive. Highly described in the lower limbs, NHOs can also develop in the upper limb, with specific characteristics depending on their location. This article provides a summary of the diagnostic and therapeutic management of NHOs in the upper limb, based on the current literature.

RESUMEN

This study aimed to analyze upper-extremity combat-related injuries (CRIs) and non-combat-related injuries (NCRIs) treated in the French Forward Surgical Team currently deployed in Gao, Mali. A retrospective study was conducted using the French Military Health Service OpEX surgical database from February 2013 to March 2020. All patients operated on for upper-extremity injury were included: 224 patients, with a mean age of 28.15 years, for 249 upper-extremity injuries. Seventy-six (33.9%) sustained CRIs and 148 (66.1%) NCRIs. Multiple upper-extremity injuries and associated injuries were significantly more common in the CRI group. The majority of NCRIs involved the hand. Debridement and wound care was the most common procedure in both groups. External fixation and fasciotomy were significantly more frequent in the CRI group, and internal fracture fixation in the NCRI group. The overall number of procedures was significantly higher in the CRI group. Due to the high frequency of upper-extremity injury in current theaters of operations, deployed orthopedic surgeons should be trained in basic hand surgery so as to optimally manage both CRIs and NCRIs.

RESUMEN

Wide-Awake Local Anesthesia No Tourniquet (WALANT) may be a satisfactory anesthesia alternative for the management of upper limb peripheral nerve palsy sequelae. The main advantages are the possibility of active patient cooperation through intraoperative active mobilization, comfort and cost reduction. The legislation about WALANT in France remains unclear; the modalities of lidocaine epinephrine injection should be redefined. For palliative upper limb surgery, WALANT allows the surgeon to adjust the tension on the tendon transfer intraoperatively. Level 1 studies are needed to evaluate the effectiveness of WALANT relative to standard anesthesia techniques (regional/general anesthesia).

RESUMEN

The aim of our study is to describe the assessment of the upper limb in tetraplegic patients to follow his (her) neurological progression and to define the medical or surgical treatment program. We selected upper limb assessment tools and scales for tetraplegic patients described in the medical literature through a PubMed search over the last four decades. For each method, we present the implementation rules and its metrological properties, including its validity in French. We selected five clinical scales for functional evaluation of grasping, as well as four scales for evaluating the overall function of these patients. Finally, we identified three complementary precision assessment tools. The AIS (ASIA Impairment Scale) classification describes the level and the severity of the spinal cord lesion. The Giens classification is more practical for describing the upper limb in middle and low tetraplegia. Impairments can be assessed with most common generic scales and nonspecific measurement devices: range of motion, strength, sensory loss, spasticity, joint pain. Measurement of pinch and grip strength is widely used and easy to perform. The Capabilities of Upper Extremity (CUE) and the Jebsen Taylor Test are the best validated and usable scales. At a general functional level, the Spinal Cord Independence Measure (SCIM) is the most relevant scale in these patients. Motor nerve blocks, electromyography, movement analysis and echography are promising additional methods. Assessment of the upper limb of tetraplegic patients relies both on generic and specific assessment tools and scales.

RESUMEN

Neuro-orthopedic complications of the upper limb affect all of its joints and lead to a multitude of clinical pictures. The clinical assessment, which should be multidisciplinary, will have to answer basic questions to define the goal(s) and the appropriate surgical strategy. What is the patient's and family's complaint? What is the possible utility of the deformities? What is the type of deformity? Is it reducible or not? What is the contribution of the upper limb deformities versus that of any associated injuries to the discomfort? Several difficulties exist in the clinical assessment: evaluation of the antagonists especially the wrist extensor muscles; the intrinsic deformity component, which can be masked by the extrinsic component when retracted, the muscles responsible for a wrist flexion contracture and the complex shoulder deformities. Many patients have multiple deformities, which creates a problem for the hierarchy of corrections depending on the objectives. The answer to these questions helps to define a clear objective that will be formalized in a contract with the patient and subsequently to define the surgical strategy. Surgery is based on a simple principle: relax the muscles on the side of the deformity, either by selective neurotomy if there is a simple hypertonia, or by a tendon procedure if the muscle is retracted; compensate for the antagonists if they are deficient, and potentially stabilize the joint. Conservative procedures are preferred to preserve the possibility of functional recovery in the future. The wide range of medical and surgical solutions allows the patient's care to be personalized. In the upper limb, the results are better for hygienic, positioning, and analgesic objectives. They remain more difficult to obtain for functional objectives, due to the biomechanical complexity of gripping.

RESUMEN

Prior to the 1950s, relatively few patients who suffered a transection of the cervical spinal cord survived their injury. Improved medical care and better coordination have resulted in greater numbers of patients surviving and leaving the hospital. The pioneering work of individual surgeons during the 1960s and 1970s stimulated interest in surgical restoration of upper limb function in tetraplegic patients. Since the publication of Moberg's monograph in 1978, surgical improvement of the upper limbs is regarded as one of the options that should be offered to tetraplegic individuals to improve their function. Patients are classified according to the level of spinal cord injury and the residual motor function (international classification: groups 1-9). Surgical procedures are adapted to the motor level for each group of patients. Indications for these procedures are well standardized, the techniques are well mastered, and predictable results can be expected. New nerve transfer techniques have been developed in recent years; they are currently being evaluated.

RESUMEN

The clinical assessment of a hypertonic upper limb in central neurological diseases should be analytical, systematic (shoulder, elbow, extrinsic and intrinsic hand) and focused on the patient or caregiver's wishes and on the expected objectives (esthetic, hygienic, functional). Nerve blocks can help to separate mixed contractures, show the existence of antagonist muscles or find a starter muscle in dystonia patterns. The etiology (especially the evolving nature of the disease), general health condition (especially in older adults), associated deficits (cerebellar, sensory and cognitive; hemineglect) are considered together to arrive at a contract with patients and/or caregivers.

RESUMEN

The aim of this study was to investigate the effect of hand deformity on upper-limb function and health-related quality of life (HRQOL) in children with hemiplegic cerebral palsy (CP). The study included 44 children with hemiplegic CP between the ages of 6 and 14 years (mean age, 10.04 years; SD, 3.1; 23 males, 21 females). The Manual Ability Classification System (MACS) and Gross Motor Function Classification System (GMFCS) were used, with the Zancolli classification to characterize hand deformities on the more affected side. Upper-limb function was assessed in terms of unilateral capacity (Quality of Upper Extremity Skills Test: QUEST) and bimanual performance (Children's Hand-use Experience Questionnaire: CHEQ), while HRQOL was evaluated on the KIDSCREEN-27 questionnaire. Comparison of bimanual performance and unilateral capacity in children with Zancolli level 1 and 2a hemiplegic CP found statistically significant differences (p < 0.01). There was also a significant difference on the HRQOL 'physical activities and health' subdomain, in favor of Zancolli level I deformity (p = 0.003), but not on the other HRQOL domains (p > 0.05). Upper-limb function and the HRQOL physical health domain were poorer with greater hand deformity in children with hemiplegic CP.

RESUMEN

Necrotizing fasciitis (NF) is both a limb-and life-threatening disease that affects skin, hypodermis as well as superficial fascia and deep fascia by rapidly progressive necrosis. Although this serious infection frequently occurs in the extremities, upper limb NF is a rare clinical presentation. The present study attempted to evaluate the clinical profiles, paraclinical findings, treatment modalities, outcomes and predictors of morbidity and mortality in patients with NF of the upper extremity. The validity of the Laboratory Risk Indicator for Necrotising Fasciitis (LRINEC) scoring system was also assessed. Nineteen patients who were treated between January 2010 and December 2019 for NF of the upper extremity were eligible for this study. Data including demographics, clinical signs, paraclinical findings, treatment and outcomes were collected retrospectively from our medical records. Fisher's exact test was used to analyze predictive factors for mortality and morbidity. The mean age was 62 years, with a male predominance. The most common comorbidity was diabetes mellitus (42%). Main clinical manifestations were pain (79%), tense edema (79%) and a large infiltrated swollen erythematous plaque (58%). Severe sepsis and septic shock were identified in 32% and 21% of patients, respectively. Thirteen of our 19 patients (68%) were identified as having a high or intermediate likelihood of NF based of the LRINEC scoring system, while the other 6 (32%) were classified as having low likelihood. All patients received systemic broad spectrum antibiotic therapy in addition to surgical debridement. Two patients (10%) died and one (5%) required amputation. Mortality was associated with septic shock (p = 0.006), delay in surgery >24 h (p = 0.018), creatininemia >141 mmol/l (p = 0.018) and LRINEC score ≥ 8 (p = 0.035). Otherwise, anemia (p = 0.021), hypercreatininemia (p = 0.001) and delayed surgical debridement (p = 0.001) were risk factors for morbidity and mortality. The surviving patients underwent reconstructive surgery (skin grafting after wound preparation by using vacuum therapy) with positive outcome. Early diagnosis coupled with emergent surgical debridement and broad-spectrum empiric antibiotic therapy are the keystones of a successful outcome. The LRINEC score was not strongly correlated to the true diagnosis of NF and was a prognostic tool rather than a diagnostic one.

RESUMEN

AIM OF THE STUDY: The purpose of our study was to review the population at risk of upper limb arterial injury, to determinate the rate of upper limb salvage and the predictive factors of limb loss. METHODS: This was a retrospective study, involving 128 patients with upper extremity arterial trauma operated between January first, 2006 and June 30, 2017. Exclusion criteria were arterial ligation, primary limb amputation and arterial iatrogenic injuries. End points were immediate technical success, primary patency and limb salvage rate. RESULTS: The average age was 27.7 years with a sex ratio M/F=41, causes of trauma were self-inflicted wounds (51%), assaults (23%), road traffic accidents (10%), work accidents (9%) and domestic accidents (7%). Injured arteries were brachial (66.5%) usually because of self-inflicted injuries; arteries of the forearm (31%) and axillery arteries (2.5%). The techniques of arterial repair were vein graft interposition in 52% of cases, end-to-end anastomosis in 23%, primary arterial repair in 21% and venous patch in 4%. Eight reconstructions occluded during the first week (6.25%). Four patients required secondary amputation and limb salvage rate was 96.8%. After a median follow-up time of 62 days, only 21% were followed at 3 months. Mechanism of injury, soft tissue loss and arterial reconstruction thromboses were selected as factors influencing the rate of limb salvage. One death occurred at day 14 secondary to multi-component poly-trauma. CONCLUSION: Prompt diagnosis, appropriate multidisciplinary management of the upper extremity arterial trauma and a readiness to revise the vascular repair early in the event of failure will maximize patient survival and upper extremity salvage. Associated soft tissue injury is a poor limb salvage factor.
