Abstract. Nerve transfer has become a common and often effective reconstructive strategy for proximal and complex peripheral nerve injuries of the upper limb. This case-based discussion explores the principles and potential benefits of nerve transfer surgery and offers in-depth discussion of several established and valuable techniques including: motor transfer for elbow flexion after
Helical plates are preferably used for proximal humeral shaft fracture fixation and potentially avoid radial nerve irritation as compared to straight plates. Aims:(1) to investigate the safety of applying different long plate designs (straight, 45°-, 90°-helical and ALPS) in MIPO-technique to the humerus. (2) to assess and compare their distances to adjacent anatomical structures at risk. MIPO was performed in 16 human cadaveric humeri using either a straight plate (group1), a 45°-helical (group2), a 90°-helical (group3) or an ALPS (group4). Using CT-angiography, distances between brachial arteries and plates were evaluated. Following, all specimens were dissected, and distances to the axillary, radial and
The transfer of part of the ulnar nerve to the
The patterns of nerve and associated skeletal injury were reviewed in 84 patients referred to the brachial plexus service who had damage predominantly to the infraclavicular brachial plexus and its branches. Patients fell into four categories: 1. Anterior glenohumeral dislocation (46 cases); 2. ‘Occult’ shoulder dislocation or scapular fracture (17 cases); 3. Humeral neck fracture (11 cases); 4. Arm hyperextension (9 cases). The axillary (38/46) and ulnar (36/46) nerves were most commonly injured as a result of glenohumeral dislocation. The axillary nerve was ruptured in only 2 patients who had suffered high energy trauma. Ulnar nerve recovery was often incomplete. ‘Occult’ dislocation refers to patients who had no recorded shoulder dislocation but the history was suggestive that dislocation had occurred with spontaneous reduction. These patients and those with scapular fractures had a similar pattern of nerve involvement to those with known dislocation, but the axillary nerve was ruptured in 11 of 17 cases. In cases of humeral neck fracture, nerve injury resulted from medial displacement of the humeral shaft. Surgery was performed in 7 cases to reduce and fix the fracture. Arm hyperextension cases were characterised by injury to the
We compared the quantitative electromyographic activity of the elbow flexors during four exercises (forced inspiration, forced expiration, trunk flexion and attempted elbow flexion), following intercostal nerve transfer to the
Objective: Search for operation timing and methods for obstetrical brachial plexus injury(OBPI). Methods: Thirty-two children with upper OBPI were treated by microsurgical procedure from October 1997 through April 2001, The average time of operation is 10 months of age, ranged from 3 months to 24 months, of which 19 were below 6 months while 13 were over 6 months. Surgical procedure included neurolysis (n=11), coaption after resection of the neroma without function(n=6), phrenic nerve transfer to anterior cord of upper trunkor
The standard approach is through the deltopectoral interval. Among patients with prior incisions, one makes every effort to either utilise the old incision or to incorporate it into a longer incision that will allow one to approach the deltopectoral interval and retract the deltoid laterally. The deltopectoral interval is most easily developed just distal to the clavicle, where there is a natural infraclavicular triangle of fat that separates the deltoid and pectoralis major muscles even in very scarred or stiff shoulders. Typically, the deltoid is retracted laterally leaving the cephalic vein on the medial aspect of the exposure. The anterior border of the deltoid is mobilised from the clavicle to its insertion on the humerus. The anterior portion of the deltoid insertion together with the more distal periosteum of the humerus may be elevated slightly. The next step is to identify the plane between the conjoined tendon group and the subscapularis muscle. Dissection in this area must be done very carefully due to the close proximity of the neurovascular group, the axillary nerve, and the
Non-operative management has frequently been adopted for closed injuries of the infraclavicular brachial plexus and its branches in the belief that spontaneous recovery is likely to occur, and surgical exploration is performed only if recovery has not occurred in the expected time. This paper correlates the clinical and electrophysiological features with the operative findings in six patients with such injuries. The axillary nerve was ruptured in all six patients, the
Purpose:. We aimed to assess the short and medium term complications of patients who had undergone Latarjet procedures. We also compared this to a group of patients who over a similar period underwent an open Bankhart procedure to assess the complication profiles between the two groups. Method:. We retrospectively reviewed the notes and X-rays of all patients identified by surgical log books and or operation codes for instability. Eighty seven patients (88 shoulders) underwent Latarjet procedures between 2002 and 2010. Patients were phoned to obtain a telephonic Oxford shoulder score. There were 44 patients with 46 shoulders in the open Bankhart group. Results:. Complications were seen in 27 patients in the Latarjet group. These included: 5 nerve injuries (3 axillary nerves, 1
We studied the motor evoked potentials (MEP) in the biceps of 25 patients with traumatic brachial plexus palsy from root avulsion after cross-innervation by intercostal nerves. We used transcranial, transcervical and transthoracic magnetic stimulation at 8 to 235 months (mean 51) after transfer of intercostal nerves to the
Compared with general anaesthesia, brachial plexus (BP) anaesthesia improves patient satisfaction and accelerates hospital discharge after ambulatory hand surgery; however, variable success rates and typical onset times up to 30 minutes have limited its widespread use. Increasing availability of high-resolution portable ultrasound has renewed interest in more proximal approaches to the BP, previously thought to carry unacceptable risk. The aim of this study was to compare the onset times of ultrasound guided supraclavicular and infraclavicular BP block in patients undergoing ambulatory hand surgery. With ethics committee approval, patients presenting for hand surgery were prospectively randomised to either supraclavicular (trunks/divisions) or infraclavicular (cords) BP block. A single experienced operator (MF) placed all blocks using ultrasound only guidance. A blinded observer (AP, SY) assessed pinprick sensory and motor block on 3-point scale (normal=2, reduced=1, absent=0) in the median, ulnar, radial and
Aim: We prove the importance of the medial ligamentary system of the elbow for its stability and the usefulness of the ligamentoplasty by palmaris longus tendon as reconstructive technique. Methods and patients: 9 patients aged between 17 and 58 (17,18,28,32,35,38,40,56,58,), 6 male, 3 female suffered the following injuries:1)elbow luxation or sub-luxation with rupture of the medial collateral elbow ligament, associated with: 1)Forearm bone fractures, 2)Ulnar nerve pulsy, 3)fracture of the coronoidal process, 4)Fracture of the radius head, 5)fracture of the humerus with radial and
Rotator cuff pathology is the main cause of shoulder pain and dysfunction in older adults. When a rotator cuff tear involves the subscapularis tendon, the symptoms are usually more severe and the prognosis after surgery must be guarded. Isolated subscapularis tears represent 18% of all rotator cuff tears and arthroscopic repair is a good alternative primary treatment. However, when the tendon is deemed irreparable, tendon transfers are the only option for younger or high-functioning patients. The aim of this review is to describe the indications, biomechanical principles, and outcomes which have been reported for tendon transfers, which are available for the treatment of irreparable subscapularis tears. The best tendon to be transferred remains controversial. Pectoralis major transfer was described more than 30 years ago to treat patients with failed surgery for instability of the shoulder. It has subsequently been used extensively to manage irreparable subscapularis tendon tears in many clinical settings. Although pectoralis major reproduces the position and orientation of the subscapularis in the coronal plane, its position in the axial plane – anterior to the rib cage – is clearly different and does not allow it to function as an ideal transfer. Consistent relief of pain and moderate recovery of strength and function have been reported following the use of this transfer. In an attempt to improve on these results, latissimus dorsi tendon transfer was proposed as an alternative and the technique has evolved from an open to an arthroscopic procedure. Satisfactory relief of pain and improvements in functional shoulder scores have recently been reported following its use. Both pectoralis minor and upper trapezius transfers have also been used in these patients, but the outcomes that have been reported do not support their widespread use. Cite this article:
Aim: To study the functional outcome ofmusculocutaneous nerve neurotization in brachial plexus palsy patients. Methods: From 1998 to 2001, 51 adult patients (mean age 24,6 years) with posttraumatic brachial plexus palsy were operated. Exploration of the brachial plexus was performed in 39 patients with a mean denervation time of 6 months (1 to 14 months). Seven patients had an extended infraclavicular lesion, while from the 32 supraclavicular lesions, 21 had the element of avulsion (4 global, 10 four-root and 7 three-roots avulsions). Neurotization of the musculocutaneous was performed in 25 via nerve grafts from intraplexus donors (C5, C6, C7)and from extraplexus donors in 14. In 7 patients, the phrenic was used alone or with intraplexus donor (5), in 3 cases the accessory nerve, in one patient the accessory and cervical plexus motor branches and þnally in 3 patients 3 intercostal nerves were used. Results: All intraplexus neurotizations of the
Acute trauma and repetitive nicrotrauma connected with certain athletic activities are oftenmentioned when describing the etiology of nerve entrapment syndromes. According to the literature it is obvious that nerve entrapment syndromes in athletes are not as rare as they were once considered to be. Certain sports or physical activities have been mentioned that lead to specific nerve entrapment syndromes – for example, cyclist’s palsy and bowler’s thumb. Unlike nerve entrapment syndromes, vascular and neurovascular syndromes in athletes seem to be more common and have been described in greater detail, while nerve entrapment syndromes in athletes have been reported only recently. To support this contention, I present currently available information about nerve entrapment syndromes in athletes. For each syndrome possible cause of compression, clinical symptoms and signs, and the most effective treatment is presented. On the upper extremity are described: spinal accessory nerve, thoracic outlet syndrome, brachial plexus, long thoracic nerve, suprascapular nerve, axillary
Introduction and purpose: Different neurovascular structures may be damaged when making arthroscopic portals to the shoulder joint. The description of new portals poses new challenges. The goal of the present study is to provide an update on the anatomic vasculonervous responses of the current approaches to shoulder arthroscopy. Materials and methods: 16 fresh cadavers were systematically dissected. The most usual arthroscopic portals were marked and, then, the dissection started on a plane-to-plane basis. Relationships were identified and distances were measured to the most important neurovascular elements with a standard caliber (accuracy: 0.5mm). Results: The portals studied and the structures at risk were the following:. * Posterior portal: anterior branch of the axillary nerve and posterior circumflex artery 3.4 cm (range: 1.4 – 5); cutaneous branch of the axillary nerve 6.3 cm (range: 3.8 – 8.3), suprascapular nerve 2.8 cm (range: 2.1–3.3). * Anterosuperior portal: main branch of the
Purpose of the study: We compared the reinnervation capacities of two nerve transfers onto the common trunk of the
Introduction: Latarjete operation for anterior shoulder instability, first described by Latarjete in 1954 consists of transfer of the coracoid process through the sub-scapularis tendon to the neck of the scapula. Many modifications were described in the English literature as described by Mc Murray in 1958, by Bonin in 1969 or May in 1970. In 1985, Braly and Tullos emphasized that the Bankart lesion, when present, should be corrected. Rockwood transplants the entire coracoid process onto the neck by “laying it flat” onto the neck of the scapula using two screws instead of one, which gives a larger base for the coracoid transplant. The disadvantages of this procedure, as described in the English literature, are relative shortening of the sub-scapularis tendon, thereby decreasing internal rotation power, limited external rotation and the possibility to damage the
Vascular compromise due to arterial injury is a rare but serious complication of a proximal humeral fracture. The aims of this study were to report its incidence in a large urban population, and to identify clinical and radiological factors which are associated with this complication. We also evaluated the results of the use of our protocol for the management of these injuries. A total of 3,497 adult patients with a proximal humeral fracture were managed between January 2015 and December 2022 in a single tertiary trauma centre. Their mean age was 66.7 years (18 to 103) and 2,510 (72%) were female. We compared the demographic data, clinical features, and configuration of those whose fracture was complicated by vascular compromise with those of the remaining patients. The incidence of vascular compromise was calculated from national population data, and predictive factors for its occurrence were investigated using univariate analysis.Aims
