A total of 11 patients with combined traumatic injuries of the brachial plexus and spinal cord were reviewed retrospectively. Brachial plexus paralysis in such dual injuries tends to be diagnosed and treated late and the prognosis is usually poor. The associated injuries, which were all on the same side as the plexus lesion, were to the head (nine cases), shoulder girdle (five), thorax (nine) and upper limb (seven). These other injuries were responsible for the delayed diagnosis of brachial plexus paralysis and the poor prognosis was probably because of the delay in starting treatment and the severity of the associated injuries. When such injuries are detected in patients with spinal cord trauma, it is important to consider the possibility of involvement of the brachial plexus

We present our experience of managing patients with iatropathic brachial plexus injury after delayed fixation of a fracture of the clavicle. It is a retrospective cohort study of patients treated at our peripheral nerve injury unit and a single illustrative case report. We identified 21 patients in whom a brachial plexus injury occurred as a direct consequence of fixation of a fracture of the clavicle between September 2000 and September 2011. The predominant injury involved the C5/C6 nerves, upper trunk, lateral cord and the suprascapular nerve. In all patients, the injured nerve was found to be tethered to the under surface of the clavicle by scar tissue at the site of the fracture and was usually associated with pathognomonic neuropathic pain and paralysis. Delayed fixation of a fracture of the clavicle, especially between two and four weeks after injury, can result in iatropathic brachial plexus injury. The risk can be reduced by thorough release of the tissues from the inferior surface of the clavicle before mobilisation of the fracture fragments. If features of nerve damage appear post-operatively urgent specialist referral is recommended. Cite this article: Bone Joint J 2013;95-B:106–10

We studied a consecutive series of 58 patients with penetrating missile injuries of the brachial plexus to establish the indications for exploration and review the results of operation. At a mean of 17 weeks after the initial injury, 51 patients were operated on for known or suspected vascular injury (16), severe persistent pain (35) or complete loss of function in the distribution of one or more elements of the brachial plexus (51). Repair of the nerve and vascular lesions abolished, or significantly relieved, severe pain in 33 patients (94%). Of the 36 patients who underwent nerve graft of one or more elements of the plexus, good or useful results were obtained in 26 (72%). Poor results were observed after repairs of the medial cord and ulnar nerve, and in patients with associated injury of the spinal cord. Neurolysis of lesions in continuity produced good or useful results in 21 of 23 patients (91%). We consider that a vigorous approach is justified in the treatment of penetrating missile injury of the brachial plexus. Primary intervention is mandatory when there is evidence of a vascular lesion. Worthwhile results can be achieved with early secondary intervention in patients with debilitating pain, failure to progress and progression of the lesion while under observation. There is cause for optimism in nerve repair, particularly of the roots C5, C6 and C7 and of the lateral and posterior cords, but the prognosis for complete lesions of the plexus associated with damage to the cervical spinal cord is particularly poor

Clavicular fractures are occasionally responsible for lesions of the brachial plexus. The symptoms are usually delayed and due to compression by hypertrophic callus, nonunion or a subclavian pseudoaneurysm. We describe a patient in whom a displaced bone fragment was pressing on the retroclavicular part of the brachial plexus, leading to early symptoms of a lesion of the posterior cord. Internal fixation of the clavicle and external neurolysis of the brachial plexus gave an almost full recovery

Our unit has pursued a policy of using donor nerves from the same limb for grafting. Nerves which have already been affected by the primary injury are selected where possible, thus avoiding any new sensory deficit. 36 of the 41 brachial plexus repairs were available for outcome data collected prospectively over 2 years. Over a nine year period, donor nerves used for the 41 brachial plexus repairs included the lateral cutaneous nerve of the forearm, superficial radial, medial cutaneous of the forearm, ulnar and sural nerves. Patients were grouped into having injured nerve grafts only (A), injured and uninjured nerve grafts (B) and uninjured nerve grafts. The repaired brachial plexus nerves were assessed by measuring the MRC grading of the power of movement of the muscle innervated by that nerve (i.e. elbow flexion for musculocutaneous nerve). These were graded as good (MRC grading 3 or better), fair (MRC grade 1 or 2), or poor (MRC 0). The greatest success for nerve grafting was elbow flexion with good results in 22 out of 27 assessments. Using Mann-Whitney test, Group A had significantly better results (p=0.025) than group C. However, ignoring the poorer results of shoulder abduction there was no significant difference between all 3 groups of patients. We conclude that using injured nerve grafts taken distal to the lesion in the brachial plexus is as effective as using nerve material from an uninjured limb

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

Brachial plexus tumours (BPT) and peripheral nerve sheath tumours (PNST) are largely benign in nature, with malignant tumours being rare and presenting significant surgical challenges. Excision of benign tumours may relieve pain and other symptomology. This retrospective study analysed data from 138 PNST and 92 BPT patients managed by a single consultant orthopaedic or plastic surgeon experienced in nerve tumour surgery between January 1999 to December 2019. The most common benign tumours were schwannomas and neurofibromas, with sarcomas being the most common malignant tumour. In the PNST group 30 patients were managed by observation only. Twenty patients underwent trucut biopsy, 21 patients underwent biopsy and surgical excision and 56 patients underwent surgical excision only. There were nine complications, with two significant neurological deficits requiring further surgical intervention. No recurrence of tumours occurred in this group. In the BPT group 16 patients were managed by observation only. Seven patients underwent trucut biopsy, 16 patients biopsy and surgical excision and 44 BPT patients underwent surgical excision only. Sixteen patients had complications with two significant complications requiring urgent further surgical intervention. Seven patients had recurrence of tumours which presented as metastases, with three patients requiring further surgery to remove recurrence of tumours. BPT patients are more complex and present with both benign and malignant lesions and are therefore more prone to complications due to the complex nature of the surgery and higher recurrence rate of tumours than PNST. Benign tumours in both groups can be safely managed conservatively if patients’ symptomology is acceptable

Injuries to the limb are the most frequent cause of permanent disability following combat wounds. We reviewed the medical records of 450 soldiers to determine the type of upper limb nerve injuries sustained, the rate of remaining motor and sensory deficits at final follow-up, and the type of Army disability ratings granted. Of 189 soldiers with an injury of the upper limb, 70 had nerve-related trauma. There were 62 men and eight women with a mean age of 25 years (18 to 49). Disabilities due to nerve injuries were associated with loss of function, neuropathic pain or both. The mean nerve-related disability was 26% (0% to 70%), accounting for over one-half of this cohort’s cumulative disability. Patients injured in an explosion had higher disability ratings than those injured by gunshot. The ulnar nerve was most commonly injured, but most disability was associated with radial nerve trauma. In terms of the final outcome, at military discharge 59 subjects (84%) experienced persistent weakness, 48 (69%) had a persistent sensory deficit and 17 (24%) experienced chronic pain from scar-related or neuropathic pain. Nerve injury was the cause of frequent and substantial disability in our cohort of wounded soldiers.

Aims . To analyse the influence of upper extremity trauma on the long-term outcome of polytraumatised patients. . Patients and Methods. A total of 629 multiply injured patients were included in a follow-up study at least ten years after injury (mean age 26.5 years, standard deviation 12.4). The extent of the patients’ injury was classified using the Injury Severity Score. Outcome was measured using the Hannover Score for Polytrauma Outcome (HASPOC), Short Form (SF)-12, rehabilitation duration, and employment status. Outcomes for patients with and without a fracture of the upper extremity were compared and analysed with regard to specific fracture regions and any additional brachial plexus lesion. Results. In all, 307 multiply-injured patients with and 322 without upper extremity injuries were included in the study. The groups with and without upper limb injuries were similar with respect to demographic data and injury pattern, except for midface trauma. There were no significant differences in the long-term outcome. In patients with brachial plexus lesions there were significantly more who were unemployed, required greater retraining and a worse HASPOC. Conclusion. Injuries to the upper extremities seem to have limited effect on long-term outcome in patients with polytrauma, as long as no injury was caused to the brachial plexus.

We describe the results after open reduction and internal fixation of 22 consecutive displaced fractures of the glenoid with a mean follow-up of ten years. A posterior approach was used in 16 patients and an anterior in six, the approach being chosen according to the Ideberg classification of the fractures. The fixation failed in two patients, one of whom required a further operation. There were two cases of deep infection. At follow-up the median Constant score was 94% (mean 79%, range 17 to 100). The score was less than 50% in four patients, including the two who became infected. A further two had an associated complete palsy of the brachial plexus

We evaluated 242 consecutive fractures of the clavicle in adults which had been treated conservatively. Of these, 66 (27%) were originally in the middle third of the clavicle and had been completely displaced. We reviewed 52 of these patients at a mean of 38 months after injury. Eight of the 52 fractures (15%) had developed nonunion, and 16 patients (31%) reported unsatisfactory results. Thirteen patients had mild to moderate residual pain and 15 had some evidence of brachial plexus irritation. Of the 28 who had cosmetic complaints, only 11 considered accepting corrective surgery. No patient had significant impairment of range of movement or shoulder strength as a result of the injury. We found that initial shortening at the fracture of ≥20 mm had a highly significant association with nonunion (p < 0.0001) and the chance of an unsatisfactory result. Final shortening of 20 mm or more was associated with an unsatisfactory result, but not with nonunion. No other patient variable, treatment factor, or fracture characteristic had a significant effect on outcome. We now recommend open reduction and internal fixation of severely displaced fractures of the middle third of the clavicle in adult patients

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

Aims

The purpose was to compare operative treatment with a volar plate and nonoperative treatment of displaced distal radius fractures in patients aged 65 years and over in a cost-effectiveness analysis.

Aims

The primary aim of this study was to determine if delayed clavicular fixation results in a greater risk of operative complications and revision surgery.

The outcomes of 261 nerve injuries in 100 patients were graded good in 173 cases (66%), fair in 70 (26.8%) and poor in 18 (6.9%) at the final review (median 28.4 months (1.3 to 64.2)). The initial grades for the 42 sutures and graft were 11 good, 14 fair and 17 poor. After subsequent revision repairs in seven, neurolyses in 11 and free vascularised fasciocutaneous flaps in 11, the final grades were 15 good, 18 fair and nine poor. Pain was relieved in 30 of 36 patients by nerve repair, revision of repair or neurolysis, and flaps when indicated. The difference in outcome between penetrating missile wounds and those caused by explosions was not statistically significant; in the latter group the onset of recovery from focal conduction block was delayed (mean 4.7 months (2.5 to 10.2) vs 3.8 months (0.6 to 6); p = 0.0001). A total of 42 patients (47 lower limbs) presented with an insensate foot. By final review (mean 27.4 months (20 to 36)) plantar sensation was good in 26 limbs (55%), fair in 16 (34%) and poor in five (11%). Nine patients returned to full military duties, 18 to restricted duties, 30 to sedentary work, and 43 were discharged from military service. Effective rehabilitation must be early, integrated and vigorous. The responsible surgeons must be firmly embedded in the process, at times exerting leadership.

Gunshot injuries to the shoulder are rare and difficult to manage. We present a case series of seven patients who sustained a severe shoulder injury to the non-dominant side as a result of a self-inflicted gunshot wound. We describe the injury as ‘suicide shoulder’ caused by upward and outward movement of the gun barrel as the trigger is pulled. All patients were male, with a mean age of 32 years (21 to 48). All were treated at the time of injury with initial repeated debridement, and within four weeks either by hemiarthroplasty (four patients) or arthrodesis (three patients). The hemiarthroplasty failed in one patient after 20 years due to infection and an arthrodesis was attempted, which also failed due to infection. Overall follow-up was for a mean of 26 months (12 to 44). All four hemiarthroplasty implants were removed with no feasible reconstruction ultimately possible, resulting in a poor functional outcome and no return to work. In contrast, all three primary arthrodeses eventually united, with two patients requiring revision plating and grafting. These patients returned to work with a good functional outcome. We recommend arthrodesis rather than replacement as the treatment of choice for this challenging injury.

Both conservative and operative forms of treatment have been recommended for patients with a ‘floating shoulder’. We compared the results of conservative and operative treatment in 25 patients with this injury and investigated the use of the glenopolar angle (GPA) as an indicator of the functional outcome. A total of 13 patients (ten male and three female; mean age 32.5 years (24.7 to 40.4)) were treated conservatively and 12 patients (ten male and two female; mean age 33.67 years (24.6 to 42.7)) were treated operatively by fixation of the clavicular fracture alone. Outcome was assessed using the Herscovici score, which was also related to changes in the GPA at one year post-operatively.

The mean Herscovici score was significantly better three months and two years after the injury in the operative group (p < 0.001 and p = 0.003, respectively). There was a negative correlation between the change in GPA and the Herscovici score at two years follow-up in both the conservative and operative groups, but neither were statistically significant (r = -0.295 and r = -0.19, respectively). There was a significant difference between the pre- and post-operative GPA in the operative group (p = 0.017).

When compared with conservative treatment, fixation of the clavicle alone gives better results in the treatment of patients with a floating shoulder. The GPA changes significantly with fixation of clavicle alone but there is no significant correlation between the pre-injury GPA and the final clinical outcome in these patients.

We describe 261 peripheral nerve injuries sustained in war by 100 consecutive service men and women injured in Iraq and Afghanistan. Their mean age was 26.5 years (18.1 to 42.6), the median interval between injury and first review was 4.2 months (mean 8.4 months (0.36 to 48.49)) and median follow-up was 28.4 months (mean 20.5 months (1.3 to 64.2)). The nerve lesions were predominantly focal prolonged conduction block/neurapraxia in 116 (45%), axonotmesis in 92 (35%) and neurotmesis in 53 (20%) and were evenly distributed between the upper and the lower limbs. Explosions accounted for 164 (63%): 213 (82%) nerve injuries were associated with open wounds. Two or more main nerves were injured in 70 patients. The ulnar, common peroneal and tibial nerves were most commonly injured. In 69 patients there was a vascular injury, fracture, or both at the level of the nerve lesion. Major tissue loss was present in 50 patients: amputation of at least one limb was needed in 18. A total of 36 patients continued in severe neuropathic pain.

This paper outlines the methods used in the assessment of these injuries and provides information about the depth and distribution of the nerve lesions, their associated injuries and neuropathic pain syndromes.

Fractures and nonunions of the proximal humerus are increasingly treated by open reduction and internal fixation. The extended deltopectoral approach remains the most widely used for this purpose. However, it provides only limited exposure of the lateral and posterior aspects of the proximal humerus. We have previously described the alternative extended deltoid-splitting approach. In this paper we outline variations and extensions of this technique that we have developed in the management of further patients with these fractures.

The surgical treatment of three- and four-part fractures of the proximal humerus in osteoporotic bone is difficult and there is no consensus as to which technique leads to the best outcome in elderly patients. Between 1998 and 2004 we treated 76 patients aged over 70 years with three- or four-part fractures by percutaneous reduction and internal fixation using the Humerusblock.

A displacement of the tuberosity of > 5 mm and an angulation of > 30° of the head fragment were the indications for surgery.

Of the patients 50 (51 fractures) were available for follow-up after a mean of 33.8 months (5.8 to 81). The absolute, age-related and side-related Constant scores were recorded. Of the 51 fractures, 46 (90.2%) healed primarily. Re-displacement of fragments or migration of Kirschner wires was seen in five cases. Necrosis of the humeral head developed in four patients. In three patients a secondary arthroplasty had to be performed, in two because of re-displacement and in one for necrosis of the head. There was one case of deep infection which required a further operation and one of delayed healing.

The mean Constant score of the patients with a three-part fracture was 61.2 points (35 to 87) which was 84.9% of the score for the non-injured arm. In four-part fractures it was 49.5 points (18 to 87) or 68.5% of the score for the non-injured arm.

The Humerusblock technique can provide a comfortable and mobile shoulder in elderly patients and is a satisfactory alternative to replacement and traditional techniques of internal fixation.
