radial nerve finger palsy

There are various causes of unilateral finger palsy. Its potential etiologies include peripheral neuropathy, carpal tunnel syndrome, and nerve root disorder due to myelopathy. In addition to them, similar paralysis has been reported in localized lesions of the cerebrum, classically referred to as pseudoperipheral palsy. In this report, we describe a case of an 80-year-old man who developed sudden clumsiness of the right fingers. Neurological examination showed muscle weakness mainly in the 1st and 2nd fingers (Medical Research Council grade 1-4) and normal reflexes in the extremities...

The association of radial nerve palsy and humeral shaft fracture is well known. Primary exploration and fracture fixation is recommended for open fractures and vascular injury while expectant management remains the standard of care for closed injuries. In the absence of nerve recovery, exploration and reconstruction is recommended 3 to 5 months following injury. When direct repair or nerve grafting is unlikely to achieve a suitable outcome, nerve and tendon transfers are potential options for the restoration of wrist and finger extension...

BACKGROUND: Irrecoverable radial nerve palsy (RNP) leads to the inability to extend the wrist and fingers and significant reduction in grip strength. The aim was to assess the outcomes of treating non-recovering motor RNP using the modified Merle d'Aubigné tendon transfer method. MATERIALS AND METHODS: A descriptive prospective study involved 33 patients between January 2017 and March 2019. RESULTS: Males constituted the majority (32/33 cases, 97%)...

BACKGROUND: The flexor pronator slide is an effective treatment option for ischemic contracture and contracture related to spastic cerebral palsy, but little is known about the use of the flexor pronator slide in other non-ischemic contractures. I propose a flexor pronator slide to simultaneously correct wrist and finger flexor contractures and preserve the muscle resting length. To avoid overcorrection of the deformity, I propose the use of a wide-awake local anesthesia with no tourniquet (WALANT) procedure, in which the patient is able to continually assist the surgeon in assessing the contracture release and improvement in finger movement...

RATIONALE: Radial nerve palsy in the newborn and congenital radial head dislocation (CRHD) are both rare disorders, and early diagnosis is challenging. We reported a case of an infant with concurrent presence of these 2 diseases and provide a comprehensive review of the relevant literature. The purpose of the study is to share diagnostic and treatment experiences and provide potentially valuable insights. PATIENT CONCERNS: A newborn has both radial nerve palsy and CRHD, characterized by limited wrist and fingers extension but normal flexion, normal shoulder and elbow movement on the affected side, characteristic skin lesions around the elbow, and an "audible click" at the radial head...

OBJECTIVE: This study aims to investigate the choice of intervention time and operation mode between nerve and tendon transfer for the treatment of radial nerve palsy (RNP). METHODS: 46 RNP patients underwent nerve transfer (n = 22) and tendon transfer (n = 24). The intraoperative blood loss, main incision length, operation duration, and length of hospital stay and follow-up period of patients in these two groups were recorded and compared. The range of motion (ROM) of the elbow, wrist, fingers, and thumb, the hand grip and pinch strength, the Disabilities of Arm, Shoulder, and Hand (DASH) and the 36-Item Short Form Health Survey (SF-36) scores were measured and compared preoperatively and postoperatively between the two groups...

INTRODUCTION AND IMPORTANCE: Posterior interosseous nerve syndrome secondary to compression by a synovial cyst at the elbow is a rare and often unrecognized pathology. Early management relies on complete neurolysis to achieve satisfactory functional recovery. Increasing awareness among the orthopedics will help in the early diagnosis of the disease and in the initiation of early and proper treatment. CASE PRESENTATION: In this article, we report the case of a 32-year-old patient with posterior interosseous nerve syndrome secondary to compression by a synovial cyst of the elbow...

BACKGROUND: There is no clear census as to which operative technique provides better recovery for radial nerve injuries. Therefore, in this systematic review, we examined the functional recovery, patient-reported outcomes, and complications of tendon transfer (TT) and nerve transfer (NT). METHODS: Five electronic databases were searched for studies (>10 cases per study) comparing NT and TT regardless of the study design (observational or experimental). Manual search was also conducted...

BACKGROUND: The authors describe a rare case of transient postoperative wrist and finger drop following a prone position minimally invasive surgery (MIS) lateral microdiscectomy. OBSERVATIONS: Hand and wrist drop is an unusual complication following spine surgery, especially in prone positioning. The authors' multidisciplinary team assessed a patient with this complication following MIS lateral microdiscectomy. The broad differential diagnosis included radial nerve palsy, C7 radiculopathy, stroke, and spinal cord injury...

BACKGROUND: Neuropathy may occur at some sites after catheterization for close examination of cardiac disease. Although the radial artery is considered a relatively uncom-plicated site for catheterization, the radial artery and median nerve are in relatively close proximity, with the risk of median nerve injury depending on the angle of puncture. The purpose of this study was to report the outcomes of surgery performed for conservative therapy-resistant median neuropathy following forearm catheterization...

Hourglass-like constriction (HLC) is an uncommon spontaneous mononeuropathy that is typically characterised by a sudden onset of pain followed by palsy, affecting branches of the radial (posterior interosseous nerve) and median nerves (anterior interosseous nerve). HLC of the radial nerve (RN) is rare, with only a few reported cases. Here, we report a case of a man who presented with acute wrist and finger drop due to the HLC of the RN. Surgery was recommended 5 months after clinical observation, when the lesion was resected and primarily repaired, resulting in satisfactory recovery...

INTRODUCTION: With an incidence of 2-16%, radial nerve palsy is one of the common forms of nerve injuries globally. Radial nerve palsy causes debilitating effects including loss of elbow extension, wrist drop and loss of finger extension. Reparative surgical pathways range from primary repair and neurolysis, to nerve grafting, nerve transfers, and tendon transfers. Due to ease of performance and acceptability and reproducibility of outcomes, tendon transfers are considered the gold standard of radial nerve palsy repair...

BACKGROUND: Biliary atresia (BA) is a rare cause of persistent jaundice in infants that can result in vitamin K malabsorption and vitamin K deficiency bleeding (VKDB). We present an infant with BA who developed a rapidly growing intramuscular hematoma in her upper arm after a vaccination which caused a radial nerve palsy. CASE PRESENTATION: An 82-day-old girl was referred to our hospital because of a rapidly growing left upper arm mass. She had received three doses of oral vitamin K before age 1 month...

BACKGROUND: Myofibromas are benign mesenchymal tumors, classically presenting in infants and young children in the head and neck region. Perineural involvement, especially in peripheral nerves within the upper extremity, is extremely rare in myofibromas. OBSERVATIONS: The authors present the case of a 16-year-old male with a 4-month history of an enlarging forearm mass and rapidly progressive dense motor weakness in wrist, finger, and thumb extension. Preoperative imaging and fine needle biopsy confirmed the diagnosis of a benign isolated myofibroma...

A peripheral nerve compression injury associated with surgical positioning is an important complication that might compromise quality of life. We report a rare case of posterior interosseous nerve (PIN) palsy after robotic rectal cancer surgery. A 79-year-old male with rectal cancer underwent robotic low anterior resection in a modified lithotomy position with both arms tucked at his sides with bed sheets. Following surgery, he felt difficulty moving his right wrist and fingers. A neurological examination revealed muscle weakness in the area innervated by the PIN alone without sensory disturbance, and he was diagnosed with PIN palsy...

INTRODUCTION: Supinator to posterior interosseous nerve (SPIN) transfer allows reconstruction of finger/thumb extension and thumb abduction for low radial nerve palsy, incomplete C6 tetraplegia, and brachial plexus injury affecting C7-T1. No study has compared dorsal versus volar approach to perform SPIN transfer. This comparison is studied in the present work, assessing supinator motor branch length and ability to achieve nerve transfer from either approach. METHODS: Ten fresh frozen cadavers were randomly allocated to receive either a dorsal or volar approach to PIN and supinator radial and ulnar branches (RB = radial, UB = ulnar)...

There are very few descriptions of tendon transfers designed specifically to address the reconstruction of posterior interosseous nerve palsy (PINP). Unlike a radial nerve palsy (RNP), a patient with a PINP is able to extend their wrist but in radial deviation, because of the preserved innervation of the extensor carpi radialis longus (ECRL). Tendon transfers to restore finger and thumb extension in PINP have been extrapolated from tendon transfers to restore these functions in RNP, specifically using flexor carpi radialis, not flexor carpi ulnaris, so as not to further exacerbate the distinctive radial deviation deformity of the wrist...

INTRODUCTION: The aim of this study was to find a convenient technique to evaluate the location of the radial nerve (RN) with reference to the deltoid tuberosity (DT). MATERIALS AND METHODS: Sixty-eight upper extremities, embalmed using a modified version of Thiel's method, were included in the study. The interval between the tip of the greater tubercle of the humerus and the distal tip of the lateral humeral epicondyle (LE) was defined as humeral length (HL). The most prominent point of the DT was used as the point of reference...

INTRODUCTION: Isolated radial nerve palsy is a debilitating injury that may potentially be reconstructed with either tendon transfers, nerve grafts, or nerve transfers. Currently, there is no consensus on the optimal technique for reconstruction. We performed a systematic review and analysis to determine which surgical intervention provides the best clinical outcomes. METHODS: A systematic review was conducted according to PRISMA guidelines. Twenty-nine papers met inclusion criteria...

Background: There are numerous options available for restoration of wrist and finger extension following radial nerve palsy. The aim of this study is to conduct a systematic review of the effectiveness of nerve transfer for radial nerve palsy. Methods: Electronic literature research of PubMed, Cochrane, Scopus and Lilacs database was conducted in June 2021 using the terms 'Distal nerve transfer' AND 'Radial nerve injury' 'Radial nerve palsy' OR 'Radial nerve paresis' OR 'Median nerve transfer' OR 'wrist extensor' OR 'finger extension' OR 'thumb extension' OR 'wrist motion'...
