Fractures of the clavicle in the neonate are usually diagnosed by clinical examination and confirmed by plain radiography. Exposure of newborn infants to irradiation should be avoided if possible. Following the clinical examination of 2978 neonates, 15 had suspected fractures of the clavicle. All were confirmed by ultrasound. In combination with clinical examination, ultrasound is a satisfactory alternative to radiological assessment for the diagnosis of fractures of the clavicle in newborn children

Five children with atlanto-axial rotatory fixation (AARF) in association with fractures of the clavicle are described. It is postulated that the rotary fixation is a direct result of the trauma which produces the fracture. The importance of early diagnosis is stressed, since delayed diagnosis may lead to chronic deformity. Early diagnosis depends on awareness of the possibility of AARF, and either fluoroscoping the patient in order to take appropriate spot films or imaging the atlanto-axial joint by CT. A simple classification of AARF is proposed based on distinct radiological features which differentiate subluxation from dislocation

Purpose: Injury to the clavicle is a rare cause of outlet syndrome. We report eight cases to determine the diagnostic and therapeutic features and report outcomes. Material and methods: This series of eight patients (five women and three men), mean age 48 years (11)70) sufferred from pain irradiating to the upper limb with paraesthesia in the ulnar teritorry of the hand together with diminished muscle force. The diagnosis was established 23.1 months (mean, range 1–10 years) after the initial comminutive mid-third fracture. The displaced bone which was treated orthopaedically. Standard x-rays revealed: four deformed calluses, two atrophic nonunions, one fracture with a vertical fragment (rapid osteosynthesis performed to avoid acute plexus compression) and finally one resection of the mid third (secondary to osteitis). The electromyogram confirmed the diagnosis, generally with compression of a secondary anteromedial trunk. 3D reconstruction scans (measurement of the costo-cleidal space) were obtained. Results: Pain disappeared the day after surgery as did the paraesthesia in seven out of eight patients. The clavicle healed in 13 to 18 months. Discussion: Different mechanisms can cause compression of the brachial plexus after displaced comminutive fracture of the clavicle. Different therapeutic modalities have been proposed. The outlet syndrome should be considered following displaced fractures of the mid third of the clavicle in patients presenting pain irradiating to the upper limb. The diagnosis is confirmed by electromyography. Proper analysis of the clavicle is obtained with 3D CT scan allowing adapted surgical treatment

Introduction: Pathological fracture of the clavicle is not such a rare condition. By definition the fracture occurs either without or with minimal trauma. We present a case of pathological fracture where there was a definite history of trauma; clouding the true malignant diagnosis. Case Report: A 73 year old man first presented to the Accident & Emergency Dept. of our hospital with a history of having fallen on to his left shoulder after throwing a piece of concrete, and to have developed swelling and pain around the shoulder immediately following the fall. On examination the main findings were swelling and bony tenderness over the proximal clavicle and inability to use his left shoulder due to pain. X-ray showed a fracture at the junction between the proximal 1/3 and distal 2/3 of the left clavicle, and he was given a broad arm sling for support and a one week appointment for review in the fracture clinic. Two clinic appointments later he was still complaining of pain. X-rays taken at that time showed what appeared to be some evidence of callus formation at the fracture site. Six weeks later he had clinical and radiological signs of what appeared to be “huge callus formation”. He was given a 3 month appointment for what was expected to be a final review. Before his next fracture clinic appointment, however, he became jaundiced and complained about this to his GP who felt it was obstructive jaundice and referred him to the physicians who admitted him to the hospital, and began to investigate him as to the cause of the jaundice. These investigations included an Ultrasound Scan of the abdomen which showed a bulky head of pancreas with biliary and pancreatic ductal dilatation; and a CT scan of the upper abdomen which showed the presence of a cystic mass within the caudate lobe of the liver. Soft tissue vascular encasement around the portal vein and hepatic artery were reported as in keeping with malignant infiltration. Extensive tumour was present within the retroperitoneum involving local vascular structures. He came down to the fracture clinic for his next clinic appointment from the ward. At this point he was very ill, deeply jaundiced and frail. The swelling of the clavicle was the size of a large orange, firm to touch with dilated veins. X-ray at this point showed complete radiological destruction of the medial 1/3 of the left clavicle. At this point palliative care was the mainstay of his management. A week later the chest x-ray report came back as showing collapse of the left upper lobe with whiteout appearance and bulky hilum indicating an underlying bronchogenic carcinoma. Three days later, almost 5 months after initial presentation following a fall, this patient finally succumbed to his disease. Conclusion: This patient presented with a simple fracture and was given the standard treatment for the condition. However because his treatment was compartmentalized, i.e., orthopaedics treating the orthopaedic condition, radiology doing x-rays, and physicians managing the jaundice; it took some months before the different pieces of the jig-saw puzzle were put together and the malignant diagnosis arrived at

Aims. Tobacco, in addition to being one of the greatest public health threats facing our world, is believed to have deleterious effects on bone metabolism and especially on bone healing. It has been described in the literature that patients who smoke are approximately twice as likely to develop a nonunion following a non-specific bone fracture. For clavicle fractures, this risk is unclear, as is the impact that such a complication might have on the initial management of these fractures. Methods. A systematic review and meta-analysis were performed for conservatively treated displaced midshaft clavicle fractures. Embase, PubMed, and Cochrane Central Register of Controlled Trials (via Cochrane Library) were searched from inception to 12 May 2022, with supplementary searches in Open Grey, ClinicalTrials.gov, ProQuest Dissertations & Theses, and Google Scholar. The searches were performed without limits for publication date or languages. Results. The meta-analysis included eight studies, 2,285 observations, and 304 events (nonunion). The random effects model predicted a pooled risk ratio (RR) of 3.68 (95% confidence interval 1.87 to 7.23), which can be considered significant (p = 0.003). It indicates that smoking more than triples the risk of nonunion when a fracture is treated conservatively. Conclusion. Smoking confers a RR of 3.68 for developing a nonunion in patients with a displaced middle third clavicle fracture treated conservatively. We know that most patients with pseudarthrosis will have pain and a poor functional outcome. Therefore, patients should be informed of the significantly higher risks of nonunion and offered smoking cessation efforts and counselling. Moreover, surgery should be considered for any patient who smokes with this type of fracture. Cite this article: Bone Joint J 2023;105-B(7):801–807

In an osteological collection of 3100 specimens, 70 were found with unilateral clavicular fractures which were matched with 70 randomly selected normal specimens. This formed the basis of a study of the incidence of arthritis of the acromioclavicular joint and the effect of clavicular fracture on the development of arthritis in the ipsilateral acromioclavicular joint. This was graded visually on a severity scale of 0 to 3. The incidence of moderate to severe arthritis of the acromioclavicular joint in normal specimens was 77% (100 specimens). In those with a clavicular fracture, 66 of 70 (94%) had arthritis of the acromioclavicular joint, compared to 63 of 70 (90%) on the non-injured contralateral side (p = 0.35).

Clavicles with shortening of 15 mm or less had no difference in the incidence of arthritis compared to those with shortening greater than 15 mm (p = 0.25). The location of the fracture had no effect on the development of arthritis.

The December 2023 Shoulder & Elbow Roundup. 360. looks at: Clavicle fractures: is the evidence changing practice?; Humeral shaft fractures, and another meta-analysis…let’s wait for the trials now!; Hemiarthroplasty or total elbow arthroplasty for distal humeral fractures…what does the registry say?; What to do with a first-time shoulder dislocation?; Deprivation indices and minimal clinically important difference for patient-reported outcomes after arthroscopic rotator cuff repair; Prospective randomized clinical trial of arthroscopic repair versus debridement for partial subscapularis tears; Long-term follow-up following closed reduction and early movement for simple dislocation of the elbow; Sternoclavicular joint reconstruction for traumatic acute and chronic anterior and posterior instability

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.

Introduction. Sternoclavicular dislocations are well-known adult injuries. The same traumatism causes growth-plate fracture of the medial clavicle in children and young adults. At this location, the emergence of the secondary ossification center and its bony fusion are late. We report the results of 20 cases hospitalized in the Toulouse University Hospital Center that were treated surgically. Materials & Methods. 20 patients were treated between 1993 and 2007, 17 boys and 3 girls, 16 years old (6–20). The traumatism was always violent (rugby 75%). Two physeal fractures were anteriorly displaced, and 18 posteriorly. The follow-up is 64 month (8–174). Clinical, radiographic and therapeutic characteristics were assessed. The long-term results were analysed with: an algo-functional scale (Oxford shoulder score), the subjective Constant score, a functional disability scale (Shoulder simple test), a quality of life scale (DASH), and global indicators (SANE and global satisfaction). Results. all the patients were symptomatic before surgery: pains, oedema and partial functional impotence. Only 2 dysphagia, 1 dyspnea and 1 venous circulation alteration were observed. The first clinical and radiological examination, before CT scan, didn't diagnose the injury in 8 cases. The CT scan were realized for all the patients: it diagnosed the physeal fracture and showed 4 cases of vascular or respiratory compressions. There were 5 attempts of closed reduction, without success: all the patients were surgically-treated. The open reduction were completed by pinning (12 cases) or cerclage with absorbable suture (3 cases). Per-operatory findings lead to realize costo-clavicular repair plasties with the sub-clavicular muscle (3 cases) and/or capsular-ligamentous-perosteal selective plasties (13 cases). Two cases of broken Kirschner wires were noticed, without migration. Functional outcomes are largely good or excellent: STT 11,74/12 (10–12)–OSS 12,95/60 (12–19)–DASH 2,07/100 (0–17,6)–SANE 93,16% (60–100). Discussion and Conclusion. we present the largest case series in the literature. CT scanner is the essential element of the diagnostic process and may allow the distinction between true sterno-clavicular dislocation and displaced physeal fractures. This distinction is difficult at younger ages and is facilitated by the progression of ossification. Very good results were obtained, but classical pitfalls of treatment were found: instability after closed reduction, broken K-wires, recurrent anterior instability, inesthetic scars

Retrosternal displacement of the medial aspect of the clavicle after physeal fracture is rare. We treated six patients with this injury between 1995 and 1998, all as an emergency in order to avoid complications associated with compression of adjacent mediastinal structures. Attempted closed reduction was undertaken, but all required open reduction and internal fixation using a wire suture. There were no associated complications. Five were reviewed clinically and radiologically at a minimum of one year after operation. All had regained full use of the affected arm without pain and had resumed their preinjury level of activity including sports. Follow-up radiographs showed union in the anatomical position in all patients. We recommend attempted closed reduction in the operating room, followed, if necessary, by open reduction. Internal fixation after open reduction gives stable fixation with minimal morbidity

Five consecutive unstable fractures of the distal third of the clavicle were treated by indirect open reduction and internal fixation using a temporary Bosworth-type screw. Coracoclavicular fixation provided and maintained reduction of the fracture. Healing occurred uneventfully within nine weeks in all cases. The screw was removed under local anaesthesia after healing of the fracture and there were no surgical complications. Shoulder function was restored to the pre-injury level. Temporary coracoclavicular screw fixation appears to be a valuable alternative for the treatment of type II fractures of the distal third of the clavicle.

Purpose. Plating remains the most widely employed method for the fixation of displaced diaphyseal clavicle fractures. The purpose of this study was to assess the efficacy and outcomes of diaphyseal clavicle fractures treated with intramedullary fixation using the Rockwood clavicle pin. Methods. We conducted a retrospective analysis of all diaphyseal clavicle fractures treated with intramedullary fixation using the Rockwood pin between February 2004 and March 2010. Sixty-eight procedures were carried out on 67 patients. Functional outcome was assessed using the Disability of the Arm, Shoulder and Hand (DASH) questionnaire and an overall patient satisfaction questionnaire. Results. There were 52 (77.6%) male and 15 (22.4%) female patients with an average age of 35.8 years. In 35 (51.5%) cases the injury was located on the dominant side. Fractures were classified according to the Edinburgh system with the commonest configuration being the Type 2B1 (47, 69.1%). The indications for fixation were; acute management of displaced fractures (56, 82.4%), delayed union (2, 2.9%), nonunion (8, 11.8%) and malunion (2, 2.9%). The average time to pin removal was 3.7 months and the average follow-up prior to discharge was 6.9 months. Sixty-six (97.1%) fractures united without consequence. Two (2.9%) cases of non-union were treated with repeat fixation using a contoured plate and bone graft. The most common problem encountered postoperatively was discomfort due to subcutaneous pin prominence posteriorly (12, 17.6%) which resolved following removal of the metalwork. The average DASH score was 6.04 (0–60) and 96.4% of patients rated their satisfaction with the procedure as good to excellent. Conclusion. Due to its minimally invasive technique, cosmetically favourable scar, preservation of periosteal tissue, avoidance of stress risers associated with screw removal and good clinical outcomes, the use of this device is the preferred method of treatment for displaced diaphyseal clavicle fractures in our hospital

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

Fracture of the clavicle is common and comprise 4% of all adult fractures. The incidence appears to be increasing owing to several factors, including the occurrence of many more high velocity vehicular injuries and an increase in popularity of contact sports. The most common side site for occurrence of fracture in clavicle is the middle third and the medial fractures are rare. We did our retrospective study during 2003–2005. We review 13 patients with fracture of the clavicle. There were 10 males and 3 females and 11 were left side and 2 were right side. Patients ages ranged between 15–49 years (average 29.6). The majority of fractures were caused by motorbike and quads bike accidents. 10 were classified as Neer type 1 (midshaft) and 3 were Neer type 1 (distal third). All these patients were treated with an Acumed congruent anatomical plate. The patients were followed up for 6 months to 1 years. Post-operatively patients were treated for 3 weeks in a sling, and then had physiotherapy for the next 3 weeks. All fractures were united by 7 weeks. Our complications were 1 superficial wound infection, 1 delayed union at 9 weeks, and 1 non union at 12 weeks. All patients had a full range of movement of the shoulder by the end of the 6. th. week. In the past fractures of the clavicle were treated conservatively. Currently patients want to mobilise their limbs early, and get back to work. The clinical results of the congruent anatomical plate appear to be good in terms of fracture union and early return to function in young patients. The principal advantage of this method of treatment is an anatomical reduction of the fracture and early rehabilitation with return to normal function

Fractures of the clavicle remain common in clinical practice. The main changes that have occurred in the last five years are in the indications for surgical intervention. The traditional indications remain. For example, complex cases such as compound fractures, those in which the skin is threatened, fractures of the clavicle associated with a floating shoulder, fractures of the clavicle associated with vascular injury and unstable lateral clavicle fractures. Fractures of the middle 1/3 of the clavicle with displacement of greater than 2 cm have been identified as having a poorer outcome based on patient related factors. In adults these fractures are now recommended for surgical stabilisation. A number of surgical techniques have been described including internal fixation with plates and intramedullary pins. It is the author's preference to use plate fixation as it provides stable fixation of the clavicle including rotational control. Although there are some authors that do recommend pin fixation, insertion of these pins can be technically demanding and there is a risk of displacement of undisplaced fragments. The intramedullary pins do not provide rotational control of the fracture. When performing internal fixation of clavicle fractures it is important to be aware of the risk of major neurovascular compromise. In the second quarter (from the medial edge of the clavicle) the major neurovascular structures are at risk and care is required to ensure that drills and screws do not penetrate the inferior cortex of the clavicle and violate these neurovascular structures. Adolescents with fractures of the clavicle are often managed without surgical intervention even if there is significant displacement. However, further work is required to identify the natural history of this group. Non-union of the clavicle is a relatively uncommon event. For those patients who have a persistent symptomatic non-union, surgical stabilisation and bone grafting is recommended

The December 2012 Shoulder & Elbow Roundup. 360. looks at: whether allograft is biomechanically superior in large Hill-Sachs defects; glenoid bone loss in shoulder dislocators; repairing irreparable cuff tears; acromioclavicular joint injuries; whether more radiographs equals more surgery; whether reverse TSR is cheaper than hemiarthroplasty; autologous chondrocyte implantation in the shoulder; and fracture of the clavicle

Introduction: Distal third fractures of the clavicle account for approximately 10–15% of clavicle fractures. Non union rates following conservative management can be as high as 30%. Many techniques have been described, including external fixation, k-wire fixation, and most recently, hook plate fixation. Non-absorbable sutures, and slings have also been utilised. All of these techniques are associated with complications. In addition, Hook plates require a second operation to remove the plate. This study reports the results of a simple technique using a PDS loop in the fixation of Neer type 2 fractures of the clavicle, performed in our institution. Methods: Twelve patients with Neer type 2 fractures operated by a single surgeon over three years were included in the study. The mean age was 45 (14 to 63). There were 7 male and 5 female patients. Standard postoperative protocols were followed in all patients. A 1.5 PDS cord looped around the coracoid was used to hold the reduced medial clavicular shaft fragment. Patients were followed up postoperatively at two, six and twelve weeks. Final outcomes were assessed using radiographs and the Oxford and DASH scoring systems at twelve months. Results: Ten fractures united within twelve weeks. All of these patients returned to their pre-injury activity level. There were two non unions, both in non compliant patients. One of these non unions remained asymptomatic and one patient was lost to follow up. The mean Oxford score at 12 months was 14.25 (range 12 to 16) and the mean DASH score was 5 (4–7). Conclusion: We conclude that this technique is safe, simple and cost effective. It achieves high rates of union without the need for implant removal. As with other techniques, proper patient selection is essential. We recommend this technique as an excellent treatment option when dealing with these notoriously difficult fractures

Introduction: The combined fractures of the clavicle (or A-C dislocation) and the scapular neck are complex injuries related to high energy trauma. Their management varies depending on the degree of instability and the presence of neurovascular complications. We evaluated the results of the treatment given to this rare injury. Material and Method: During a five year period (1997–2001) we treated 12 patients with floating shoulder. The injury was in all cases the result of severe road traffic accident. Nine patients were males and three females with age ranging from 20 to 51 years. Seven patients had injured the right shoulder, the remaining five having injured the left one. Eight patients had additional injuries (chest in four, head in two, fracture of the T4 with complete paraplegia in one, chest and abdominal in one). Three patients had neurovascular complications and were operated upon. Two of them with vascular injury were operated ungently and had arterial graft and stabilization of the clavicle or the A-C joint with tension band. The third patient with only neurological injury (axillary and suprascapular nerves) had similar stabilization of his clavicle. The remaining nine patients with minor displacement of the fractures and stable shoulder girdle were managed conservatively. Results: We reexamined eleven patients. The mean follow-up period was 19 months (8–56 months). In nine patients-including the three operated-the fractures had healed in satisfactory position. In the remaining two the fracture of the scapular neck was malunited, resulting in loss of shoulder normal configuration and restriction of shoulder elevation. In two of the operated patients the coexistence of neurological injury resulted in poor functional outcome. The third one-with the axillary and suprascapular nerve injury-improved in relation to the axillary nerve within six months from the injury and had a fairly useful upper extremity. In the Constant-Murley scale the score ranged from 28–89 points (average 67 points). Conclusion: In conclusion, fractures of the clavicle (or A-C dislocations) and the scapular neck are injuries of high energy and are usually encountered in multiplez injured patients. Severe displacement is usually related to instability of the shoulder girdle and neurovascular injuries; urgent operation is then necessary and the final result is often poor. In cases of severe displacement the stabilization of only the clavicle is not sufficient and open reduction and internal fixation of the scapular neck is recommended
