To collate and present epidemiological data collected by Scottish National Brachial Injury Service over the past decade. The Brachial Plexus Injury Service is based at the Victoria Infirmary, Glasgow and has been a designated National Service since 2004. It provides an integrated multidisciplinary service for traumatic brachial plexus injury and plexus tumours. The Service maintains an active archive recording details of all clinical referrals and procedures conducted by the Service over the past decade. The data presented here was derived from analysis of this database and information contained in the National Brachial Plexus Injury Service Annual Report 2010/11 & 2011/12. Data shows that there has been a steady rate in the number of referrals to the Service, particularly since 2004, with an average of 50 cases referred per annum. Of these, approximately 25% required formal surgical exploration for traumatic injury and a further 10% required surgery for brachial plexus tumour removal. The vast majority of referred cases are treated non-operatively, with appropriate support from specialist physiotherapy and occupational therapy. Referrals to the Service appear well distributed from around Scotland. However, data from 2011 shows that Greater Glasgow & Clyde is the greatest individual source of referrals and subsequent hospital admissions for surgical treatment. The commonest mechanism of brachial plexus injury appears to be secondary to falls and motorcycle RTA. Using the Disabilities of the Arm, Shoulder and Hand (DASH) Score, improved functional outcomes have been demonstrated consistently in patients who have undergone surgery for brachial plexus injuries within the Service. Over the past decade, the Brachial Plexus Injury Service has had a steady patient referral record from across the Scotland, particularly Glasgow. Data indicates that there is an on-going clinical need for provision of the service with improved outcomes and reduced functional disability in patients treated by the service. It is envisaged that data from the Service will also act as a useful planning model for the provision of UK national services in the future

Abstract. Objective. There is no specific framework for the clinical management of sports related brachial plexus injuries. Necessarily, rehabilitation is based on injury presentation and clinical diagnostics but it is unclear what the underlying evidence base to inform rehabilitative management. Methods. A systematic review of the literature was undertaken in line with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. We applied the PEO criteria to inform our search strategy to find articles that reported the rehabilitative management of brachial plexus injuries sustained while playing contact sports. An electronic search of Medline, CINAHL, SPORTDiscus and Web of Science from inception to 3rd November 2022 was conducted. MESH terms and Boolean operators were employed. We applied an English language restriction but no other filters. Manual searches of Google Scholar and citation searching of included manuscripts were also completed. All study types were considered for inclusion provided they were published as peer-reviewed primary research articles and contained relevant information. Two investigators independently carried out the searches, screened by title, abstract and full text. Two researchers independently extracted the data from included articles. Data was cross-checked by a third researcher to ensure consistency. To assess internal validity and risk of bias, the Joanna Briggs Institute (JBI) critical appraisal tools were utilised. Results. The search generated 88 articles. Following removal of duplicates, 43 papers were evaluated against the eligibility criteria. Nine were eligible for full text review, with the majority of exclusions being expert opinion articles. Eight case reports were included. One article reported three individuals, resulting in data for ten athletes. The mean age was 19.8 years (±4.09). Injuries occurred in five American football players, two wrestlers, two rugby players, and a basketball player. No two studies applied the same diagnostic terminology and the severity of injury varied widely. Burning pain and altered sensation was the most commonly reported symptom, alongside motor weakness in the upper limb. Clinical presentation and management differed by injury pattern. Traction injuries caused biceps motor weakness and atrophy of the deltoid region, whereas compression injuries led to rotator cuff weakness. In all cases treatment was separated into acute and rehabilitative management phases, however the time frames related to these differed. Acute interventions varied but essentially entailed soft tissue inflammation management. Rehabilitation approaches variously included strengthening of shoulder complex and cervical musculature. Return-to-play criteria was opaque. The methodological quality of the case reports was acceptable. Four met all nine of the JBI evaluation criteria, and a further three met at least 75% of items. Conclusion(s). There is a distinct lack of evidence supporting rehabilitation management of sports related brachial plexus injury. Through systematic review we found only eight reports, representing ten individual case studies. No trials, cohort studies, or even retrospective registry-based studies are available to inform clinical management, which, necessarily, is driven by expert opinion and application of basic rehabilitation principles. Declaration of Interest. (b) declare that there is no conflict of interest that could be perceived as prejudicing the impartiality of the research reported:I declare that there is no conflict of interest that could be perceived as prejudicing the impartiality of the research project

Aims. Brachial plexus injury (BPI) is an often devastating injury that affects patients physically and emotionally. The vast majority of the published literature is based on surgeon-graded assessment of motor outcomes, but the patient experience after BPI is not well understood. Our aim was to better understand overall life satisfaction after BPI, with the goal of identifying areas that can be addressed in future delivery of care. Methods. We conducted semi-structured interviews with 15 BPI patients after initial nerve reconstruction. The interview guide was focused on the patient’s experience after BPI, beginning with the injury itself and extending beyond surgical reconstruction. Inductive and deductive thematic analysis was used according to standard qualitative methodology to better understand overall life satisfaction after BPI, contributors to life satisfaction, and opportunities for improvement. Results. Among the 15 patients interviewed, the following themes emerged: 1) happiness and life satisfaction were noted despite limitations in physical function; 2) quality of social support influences life satisfaction during recovery from BPI; and 3) social participation and having a sense of purpose impact life satisfaction during recovery from BPI. Conclusion. How patients perceive their BPI treatment and recovery varies widely, and is not directly linked to their self-reported functional outcome. Patients with stronger social circles and activities that give them a sense of fulfillment were more likely to be satisfied with their current status. Evaluating a patient’s social network, goals, and potential supportive adaptations early in the treatment timeline through coordinated multidisciplinary care may improve overall satisfaction during recovery from BPI.

Objectives. Traumatic brachial plexus injury causes severe functional impairment of the arm. Elbow flexion is often affected. Nerve surgery or tendon transfers provide the only means to obtain improved elbow flexion. Unfortunately, the functionality of the arm often remains insufficient. Stem cell therapy could potentially improve muscle strength and avoid muscle-tendon transfer. This pilot study assesses the safety and regenerative potential of autologous bone marrow-derived mononuclear cell injection in partially denervated biceps. Methods. Nine brachial plexus patients with insufficient elbow flexion (i.e., partial denervation) received intramuscular escalating doses of autologous bone marrow-derived mononuclear cells, combined with tendon transfers. Effect parameters included biceps biopsies, motor unit analysis on needle electromyography and computerised muscle tomography, before and after cell therapy. Results. No adverse effects in vital signs, bone marrow aspiration sites, injection sites, or surgical wound were seen. After cell therapy there was a 52% decrease in muscle fibrosis (p = 0.01), an 80% increase in myofibre diameter (p = 0.007), a 50% increase in satellite cells (p = 0.045) and an 83% increase in capillary-to-myofibre ratio (p < 0.001) was shown. CT analysis demonstrated a 48% decrease in mean muscle density (p = 0.009). Motor unit analysis showed a mean increase of 36% in motor unit amplitude (p = 0.045), 22% increase in duration (p = 0.005) and 29% increase in number of phases (p = 0.002). Conclusions. Mononuclear cell injection in partly denervated muscle of brachial plexus patients is safe. The results suggest enhanced muscle reinnervation and regeneration.

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 musculocutaneous nerve (n=7) and intercostal nerves transfer to musculocutaneous nerve (n=6). The children were underwent operation by microsurgical technique and 7–0 or 9–0 nylon were used for nerve suture.

Results: Thirty cases were followed-up 21 months postoperatively, the excellent and good rate is 76.7%(23/30). The results of the children under 6 months is better than that over 6 months .

Conclusions: We concluded that the microsurgical operation might be considered at 3 to 6 months of age in infants who have shown little or no improvement in elbow flexion . Patients undergoing neurolysis and nerve coaption had more favorable outcome than those undergoing neurotization. The appropriate procedure must be selected according to the findings of exploration.

Abstract

Current knowledge regarding upper limb myotomes is based on historic papers. Recent advances in magnetic resonance imaging (MRI) and surgical exploration with intraoperative nerve stimulation now allow accurate identification of nerve root injuries in the brachial plexus. The aim of this study is to identify the myotome values of the upper limb associated with defined supraclvicular brachial plexus injuries. 57 patients with partial supraclavicular brachial plexus injuries were identified from the Scottish brachial plexus database. The average age was 28 years and most injuries secondary to motor cycle accidents or stabbings. The operative and MRI findings for each patient were checked to establish the root injuries and the muscle powers of the upper limb documented. The main patterns of injuries identified involved (C5,6), (C5,6,7), (C5,6,7,8) and (C8, T1). C5, 6 injuries were associated with loss of shoulder abduction, external rotation and elbow flexion. In 30% of the 16 cases showed some biceps action from the C7 root. C5,6,7 injuries showed a similar pattern of weakness with the additional loss of flexor carpi radialis and weakness but not total paralysis of triceps in 85% of cases. C5,6,7,8 injuries were characterised by loss of pectoralis major, lattisimus dorsi, triceps, wrist extension, finger extension and as well as weakness of the ulnar intrinsic muscles. We identified weakness of the flexor digitorum profundus to the ulnar sided digits in 83% of cases. T1 has a major input to innervation of flexors of the radial digits and thumb, as well as intrinsics. This is the largest study of myotome values in patients with surgically or radiologically confirmed injuries in the literature and presents information for general orthopaedic surgeons dealing with trauma patients for the differentiation of different patterns of brachial plexus injuries. In addition we have identified new anatomical relationships not previously described in upper limb myotomes

Scapula fractures mostly occur following high energy trauma, however, the demographics are unknown in deployed soldiers. We analysed the incidence, aetiology, associated injuries, treatment and complications of these fractures in military personnel from Afghanistan and Iraq (2004–2014). Forty-four scapula fractures from 572 upper limb fractures (7.7%) were sustained. 85% were caused by blast or gunshot wounds and 54% were open blast fractures. Multiple injuries were noted including lung, head, vascular and nerve injuries. Injury Severity Scores were almost double compared to the average upper limb injury without a scapula fracture (21 vs. 11). Brachial plexus injuries (17%) have a favourable outcome following GSW compared to blast injuries. Glenoid fractures or floating shoulders were internally fixed (10%) and resulted from high velocity gunshot wounds or mounted blast ejections. There were no cases of deep soft tissue infection or osteomyelitis and all scapula fractures united. Scapula fractures have a 20 times higher incidence in military personnel compared to the civilian population. These fractures are often associated with multiple injuries, including brachial plexus injuries, where those sustained from blast have less favourable outcome. High rates of union following fixation and low rates of infection are expected despite significant contamination and soft tissue loss

Introduction and Objective. Postoperative pain control in shoulder surgery is challenging even in arthroscopic procedures. Acute postoperative pain can last up to 48hrs despite using multimodal analgesia. Different techniques have been used to control acute pain following shoulder surgery. The most common technique currently used in shoulder surgery at the elective orthopaedic centre in Leeds is a combination of general anaesthetic (GA) and interscalene block (ISB). ISB maybe very effective, however, carries many risks and potential side effects such as brachial plexus injury and paralysis of the vagus and laryngeal recurrent nerves as well as cervical sympathetic nerve and pneumothorax. ISB can also be associated with higher incidence of neurological deficit compared to other peripheral nerve blocks; up to 14% at 10 days in some cases. As such we decided to examine the use of ISB for achieving pain control in our elective unit. Materials and Methods. A prospective consecutive series of 217 patients undergoing shoulder surgery were studied. These were grouped into 10 groups. All procedures were arthroscopic apart from shoulder arthroplasty procedures such as hemiarthroplasty and total shoulder replacements (TSRs). The choice of regional anaesthesia was ISB with GA as standard practice. Visual analogue scores (VAS) at 0hrs, 1hr, 2hrs, 4hrs and 6hrs; and total opiates intake were recorded. A one-way single factor ANOVA was used as preferred statistical analytical method to determine whether there is a difference in VAS scores and total opiates intake amongst the groups. Postoperative analgesics were used for pain relief, although these were not standardised. Results. In total shoulder replacement group, although the RSR group used more morphine on average compared to the ASR group (Mean morphine intake 6.5mg vs 3mg), this was not statistically significant (F<Fcrit; p value= 0.19). When comparing all the arthroplasty groups, the difference in mean morphine intake was also statistically not significant (F<Fcrit; p value=0.24). However, when comparing all 10 groups’ morphine intake there was a statistically significant difference amongst these groups (F>F crit; p value=0.03). Interestingly, there was a statistically significant difference in VAS at 0hrs (F>Fcrit p value=0.01); 1hrs (F>Fcrit; p value=0.00), and at 6hrs (F>Fcrit; p value=0.02) when comparing all 10 groups. Conclusions. ISB is an effective technique in achieving pain control in shoulder surgery; however, there are still variations in analgesic needs amongst groups and the use of alternative techniques should be thus explored. A future prospective study looking at acute pain for a longer period of time after shoulder surgery would explore the effectiveness of ISB in achieving pain control consistent with rehabilitation requirements

Introduction and Aims: An important prognostic factor in neonatal brachial plexus injury is the timing of biceps recovery. Although the natural history is not clear, biceps recovery after three months has been used to predict universally poor long-term shoulder function. The absence of biceps function at three months has been adopted as an indication for early microsurgery, in an attempt to improve upper limb function. e. Method: Between 1980 and 1992, 170 patients with neonatal brachial plexus injury were entered into a prospective study, which recorded details of the birth and serial examinations. Patients were grouped according to the level of injury and timing of biceps return. Twenty-nine patients were observed to have absent biceps at three months. Twenty-eight of 29 patients were available for long-term review at an average of 11 years and one month (range 5yrs 7mths–16 years). At follow-up, patients answered a questionnaire, underwent muscle strength testing, sensory evaluation, and had their shoulder function graded according to Gilbert’s modification of the Mallet score. The level of injury and time of biceps return were compared to the final outcomes. Results: The level of injury was C5/6 in 13/28 (46%), C5/6/7 in 5/28 (18%) and pan-plexus in 10/28 (36%), with a Horner’s syndrome in four patients. Of the 28 patients with absent biceps function at three months, biceps contraction was observed in 20 patients (71%) by six months. 13/13 C-5,6 patients, 3/5 C-5,6,7 patients, and 4/9 pan-plexus patients (0/4 of those with a Horner’s syndrome) regained biceps by six months. Twenty-two patients did not have plexus surgery, nine of these had subsequent shoulder surgery. At follow-up, 27 of 28 patients had at least anti-gravity biceps function. Patients who regained biceps function between three and six month had better scores for abduction (p=0.04), hand to neck (p=0.05) and hand to back (p< 0.001) than patients who regained biceps after six months. Patients with C-5, 6 lesions had better scores for external rotation (p=0.04), hand to neck (p=0.05), hand to mouth (p< 0.01) and hand to back (p< 0.001) than patients with pan-plexus lesions. Twelve of the 22 (55%) patients who did not have plexus surgery had Mallet class IV shoulders (good function). Of the C-5, 6 patients who did not have plexus surgery, 8/12 had class IV shoulders. Conclusion: This study supports the associations between prolonged neurological recovery, more extensive level of injury and worse long-term shoulder function. In patients with C-5, 6 injuries and absent biceps function at three months, good shoulder function is common in the long-term without plexus surgery. This finding is important in considering the indications for and the results of early microsurgical intervention

Myotome values for the upper limb appear to have been established in the early twentieth century based on historical work. Supraclavicular brachial plexus injuries present with a pattern of neurological loss consistent to the nerve roots affected. Recent advances in radiological imaging and intraoperative nerve stimulation have allowed confirmation of the affected nerve roots. The records of 43 patients with partial injuries to the supraclavicular brachial plexus were reviewed. The injuries covered the full range of injury patterns including those affecting C5, C5-6, C5-7, C5-8, C7-T1 and C8-T1 roots. All cases with upper plexus injuries had surgical exploration of the brachial plexus with the injury pattern being classified on the basis of whether the roots were in continuity, ruptured, or avulsed, and, if seen in continuity, the presence or absence of a response to stimulation. For lower plexus injuries the classification relied on identification of avulsed roots on Magnetic Resonance Imaging. Muscle powers recorded on clinical examination using the MRC grading system. In upper plexus injuries paralysis of flexor carpi radialis indicated involvement of C7 in addition to C5-6, and paralysis of triceps and pectoralis major suggested loss of C8 function. A major input from T1 was confirmed for flexor digitorum superficialis, flexor digitorum profundus (FDP) to the radial digits, and extensor pollicis longus. C8 was the predominant innervation to the ulnar side of FDP and intrinsic muscles innervated by the ulnar nerve with some contribution from C7. A revised myotome chart for the upper limb is proposed

We conducted a prospective evaluation of patients with anterior dislocation of the shoulder associated with a fracture of the greater tuberosity. Thirty-four anterior dislocations of the shoulder with greater tuberosity fractures were reviewed with a minimum follow-up of one year from the time of injury. Eight required open reduction. The final outcome with regard to pain, range of movements, and function was assessed in 34 patients. In open reduction, there were five good results, one fair, one poor and one patient died. In the non-operative group, results were good in 11 patients, fair in eight, poor in one, not assessed in five and one patient died. Two patients have died in this series, one in the open reduction group. Associated injuries are: axillary nerve damage (three), brachial plexus injury (one), loose fragment under the acromion (one) and stiffness of the shoulder (three). Anterior dislocations of the shoulder with fracture of the greater tuberosity do not always lead to good results. Close observation after reduction is important to check for later displacement of the fractures

Background Adhesive capsulitis of the shoulder is a painful condition that results in gradual loss of joint movement. Numerous treatment modalities have been utilised with variable benefits. Because of the risk of brachial plexus injury and fracture, manipulation under anaesthesia is considered with caution. Aim To determine the rate of manipulation under anaesthesia (MUA) following primary distension arthrogram for adhesive capsulitis of the shoulder. Patients and Methods The case notes of 40 patients (42 shoulders) between 1998 to 2004 at Glenfield Hospital, Leicester under the care of one consultant with adhesive capsulitis of the shoulder treated with distension arthrogram by using intra-articular injection of local anaesthetic, corticosteroid, contrast media and air were reviewed. Results Capsular disruption into the subscapular bursa was demonstrated in all cases. 15 of 42 (36%) shoulders underwent MUA following distension arthrogram. The average period of pain prior to distension arthrogram for these patients was 42 weeks (range: 7–156). 35 of 40 (88%) patients were pain free following primary distension arthrogram. One patient experienced a vasovagal episode during the distension arthrogram. Conclusion Distension arthrogram can be used as a therapeutic procedure for achieving symptomatic pain relief in the early phase of adhesive capsulitis and decreasing the risk of MUA of the shoulder

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 musculocutaneous nerve, with the nerve being ruptured in 8 of 9. Five had humeral shaft fracture or elbow dislocation. There was variable involvement of the median and radial nerves, with the ulnar nerve being least affected. Most cases of infraclavicular brachial plexus injury associated with shoulder dislocation can be managed without operation. Early nerve exploration and repair should be considered for:. Axillary nerve palsy without recorded shoulder dislocation or in association with fracture of the scapula. Musculocutaneous nerve palsy with median and/or radial nerve palsy. Urgent operation is necessary for nerve injury resulting from fracture of the humeral neck to relieve ongoing pressure on the nerves

We analysed the functional outcome of 27 humeral shaft fractures treated non-operatively in our unit between 1999 and 2000. The mean age of the 20 men and seven women was 37.9 years (20 to 65). Ten fractures occurred in motor vehicle accidents, eight in falls and three in assaults. The remaining six were gunshot injuries. There were 18 closed fractures and nine grade-I compound fractures. Nine fractures were oblique, eight transverse, eight comminuted and two spiral. There was radial nerve palsy in 12 patients, and one poly-trauma patient had a concomitant brachial artery injury. All patients were treated initially by closed reduction and U-slab immobilisation. Radiological union was achieved in 12 patients (44.4%) at a mean of 11 weeks. Fixation by compression plating was necessary in 51.9%, treating delayed union in eight patients, radial nerve palsy in three, nonunion in one, a brachial plexus injury in one and polytrauma in one. One patient (3,7%) developed a pseudarthrosis and refused surgery. We assessed pain, range of movement of adjacent joints, ability to perform activities of daily living and work. In patients treated by U-slab immobilisation, the mean time to full functional recovery was 18 weeks. Those who underwent surgery achieved full functional recovery a mean of eight weeks later. Transverse and short oblique fractures are prone to delayed union and we recommend they be treated by primary internal fixation

In late cases of brachial plexus palsy or when nerve reconstruction was not that beneficial, pedicled or free neurotized muscles i.e. latissimus dorsi are used to restore or enhance important functions i.e. elbow flexion or extention. During the last three years, 43 patients with brachial plexus injuries were operated in our Clinic to reconstract the paralysed extremity. In nine of them, the ipsilateral latissimus dorsi was transferred as pedicled neurotized muscle to restore elbow flexion (seven patients) and elbow extension (two patients). Two patients had free latissimus dorsi transfer, which was neurotized directly via three intercostals. The neurovascular pedicle was dissected proximally up to the subclavian vessels and posterior cord, and the muscle was raised from its origin to its insertion and tailored to simulate the shape of biceps or triceps. Then it was passed via a subcutaneous tunnel on the anterior or posterior arm. The reattachment was done with Mitek anchors on the clavicle and the radial tuberosity (elbow flexion) or on the posterior edge of the acromion and the olecranon (elbow extension). The arm was immobilized in a prefabricated splint, which was removed after six to eight weeks. After the first three months all patients had a powerful elbow flexion or extension. One of the free muscle transfers started to have elbow flexion after eight months and he is still progressing. In one patient skin necrosis and infection occurred near the elbow. The patient after IV antibiotics needed another operation to restore the distal insertion, using fascia lata. Ipsilateral latissimus dorsi, if strong enough (at least M4), is an excellent transfer for elbow flexion or extension restoration or enhancement, in late cases of brachial plexus paralysis. Contralateral latissimus is an option when the ipsilateral is weak but it takes more time to function since there is a waiting period for reinnervation

Introduction: Various surgical methods have been described to manage the problem of recurrent anterior dislocation of the shoulder. Older procedures Putti-Platt’s, Magnuson-Stack’s or Bristow;’s and Boytchev’s repair are not used today due to a high percentage of failure of 7%–17% incidence of recurrence associated with limited ROM. However, in the last decade the goal of treatment has changed. It is directed now towards restoration of normal function with full ROM of the affected shoulder, based mainly on arthroscopic stabilization or on “open” Neer’s capsular shift procedures combined with Bankart’s repair. However, during the last few years there are more and more papers dealing with a surprising unexpected high number of patients with shoulder instability following arthroscopic repair. The purpose of this study is to review the long term results of “open” Neer’s capsular shift procedure. Materials & Methods: This is a presentation of 87 (78M; 9F) consecutive patients, 19 to 47 year old (mean 23 Y) with a length of follow-up of 4Y–15Y (mean 6Y). 45 of them with traumatic recurrent anterior dislocation of the shoulder had a capsular shift procedure according to Rockwood’s modification. In 42 other patients that had a multidirectional instability with proved dislocations of the affected shoulder a Protzman’s modified capsular shift procedure was used. Results: 82/87 patients had a stable shoulder without recurrent dislocation. 3 patients had an episode of traumatic shoulder dislocation within 2 months following operation. Two other patients of 42 with multidirectional instability had a recurrence of traumatic dislocation. One patient developed partial brachial plexus injury, most probably due to traction of the affected limb following operation. 78/87 had at follow-up normal shoulder function with full ROM, and the remaining 9 patients had only a slight limitation in shoulder abduction and in external rotation. Conclusions: Based on this study, it is suggested that capsular shift procedure is an excellent method for repair of recurrent anterior shoulder dislocation, preferable to the “older” procedures, and allows restoration of shoulder stability with better functional results. This is suitable mainly for patients with structural hyperlaxity and multidirectional instability, whereas arthroscopic stabilization might be used in patients with true traumatic instability

Background. Floating shoulder (FS) is, according to Goss et al, a double disruption of the superior shoulder suspensory complex which usually results from a glenoid neck fracture and a ipsilateral midclavicular fracture. However, the interruption can interest the whole scapular belt from acromion to sterno-clavicular joint. It occurs mostly after a violent traumatism with direct lateral impact on the shoulder. That leads to complex therapeutic issues with sometimes uncertain results. Material. Between 1984 and 2009, 35 patients (30 men, 5 women), mean age 35 years [16–72] with FS, were treated in our department. Most of them sustained road accident (31cases) with polytraumatism context in 12 cases. A CT scan was realized in the majority of cases to specify the scapular fracture and look for intra-thoracic immediate complications. Mostly, glenoid neck fracture associated with a clavicular fracture has been found out (15cases). Orthopaedic treatment has been realized in 18 cases. Surgical management has been decided for open reduction of sterno-clavicular joint in 2 cases, isolated fixation of the clavicle in 9 cases, of the scapula in 3 cases, and of both scapula and clavicle in 3 cases. Criteria for clinical evaluation were an algo-functional scale (Oxford Shoulder Score, OSS), a subjective Constant Shoulder Score, a functional incapacity scale (Shoulder Simple Test, SST), scales of life quality (DASH and SF12) and global indications (Single Assessment Numeric Evaluation, SANE). Results. we noted a single migration of material. A patient presented a secondary displacement after orthopaedic treatment, and had additional surgical fixation before 6 months. In the mean follow up of 135 months [9–312], three patients were deceased and seven were unreachable. Five complained about rare pains, three of an important stiffness and chronic pains, and only one of brachial plexus injury. Functional results were satisfactory: OSS 14,75/60 [12–28], Subjective Constant score 79 [60–100], SST 10,75/12 [4–12], DASH 13,75/100 [0–84], SF12 physical 49,4 [36,8–54,8], SF12 mental 59,7 [57,2–61,8] andSANE 79% [50–100]. Discussion/conclusion. FS presents an immediate gravity because of possible intrathoracic injuries which can delay surgical treatment. FS which allowed orthopaedic treatments or required isolated fixation of the clavicle have excellent results. Scapular fractures which required surgical repair because of a significant displacement andan articular extension have more pejorative results

Study Design: To examine the innervation of the lumbar spine from patients with lower back pain, and spinal nerve roots from patients with traumatic brachial plexus injuries. Objectives: To demonstrate the presence of nerve fibres in lumbar spine structures and spinal nerve roots, and determine whether they express the sensory neuronespecific sodium channels SNS/PN3 and NaN/SNS2. Summary of background data: The anatomical and molecular basis of low back pain and sciatica is poorly understood. Previous studies have demonstrated sensory nerves in facet joint capsule and prolapsed intervertebral disc, but not in ligamentum flavum. The voltagegated sodium channels SNS/PN3 and NaN/SNS2 are expressed by sensory neurones which mediate pain, but their presence in the lumbar spine is unknown. Methods: Tissue samples (ligamentum flavum n=32; facet joint capsule n=20; intervertebral disc n=15; spinal roots n=8) were immunostained with specific antibodies to protein gene product (PGP) 9.5, a pan-neuronal marker, SNS/PN3 and NaN/SNS2. Results: PGP 9.5-immunoreactive nerve fibres were detected in 72% of ligamentum flavum and 70% of facet joint capsule but only 20% of intervertebral disc specimens. SNS/PN3-and NaN/SNS2-positive fibres were detected in 28% and 3% of ligamentum flavum and 25% and 15% of facet joint capsule specimens respectively. Numerous SNS/PN3 and NaN/SNS2-positive fibres were found in the acutely injured spinal roots, and some were still present in dorsal roots in the chronic state. Conclusions: SNS/PN3 and NaN/SNS2-immunoreactivity is present in a subset of nerve fibres in lumbar spine structures, including ligamentum flavum and injured spinal roots. This is the first time that sensory nerve fibres have been demonstrated in the ligamentum flavum, and this raises the possibility that, contrary to the conclusions of previous studies, this unique ligament may be capable of nociception. Selective SNS/PN3 and NaN/ SNS2 blocking agents may provide new effective therapy for back pain and sciatica, with fewer side effects. Other novel ion channels are being studied in these tissues

Aim: To review treatment, results and complications of pelvic ring injuries. Materials & Methods: We reviewed 39 pelvic ring injuries, mean age 37 years, referred to a tertiary unit, with mean follow up 19 months (6 to 60). Data regarding type of fracture, associated injuries, treatment, injury surgery interval, complications and outcome was documented. Results: Vehicular accidents in 21 were the commonest mechanism of injury and 30 had vertical shear fractures. There were 4 associated head injuries, 5 chest, 4 maxillo-facial, 4 perineal/ vaginal tears, 7 urological, 1 anorectal, 2 each of abdominal and ophthalmic, and 1 each of vascular, spine and brachial plexus injuries. Also there were 15 skeletal fractures, 12 soft tissue injuries and 11 associated acetabular fractures of which 8 needed fixation, and 17 had lumbosacral plexus injuries. 6 compound pelvic fractures were treated with debridement, fixation and early life saving bowel diversion. 19 patients had anterior external fixators, 9 were applied elsewhere for resuscitation. Complications: There were 10 systemic complications, 4 ARDS, 2 wound infections and 1 colovesical fistula, 1 infected pubic plate, and 3 late inguinal hernias. 8 patients had pin track infections, and 5 iatrogenic problems including 2 nerve lesions, 2 vascular injuries and 1 bladder rupture, none of which left any residual problem. Results: 20 patients had no pain, 31 were fully mobile without aids, and 22 had returned to original level of activity. 6 complained of sexual dysfunction, and 1 had double incontinence. 6 patients were on disability allowance, and 10 had full recovery of lumbosacral plexus injury. Conclusion: Severe associated injuries and soft tissue trauma significantly affect outcome and complications, inspite of sound bony fixation and healing, and multi-disciplinary management is obligatory. Posterior ring lesions were often underestimated, and anterior external fixation alone can make them worse. Early colostomy is lifesaving in compound pelvic fractures. Early involvement of a specialist surgeon is desirable for optimal outcome, which can be achieved in most patients
