Purpose: The floating shoulder is a special entity in traumatology of the upper limb. Bioechanically, the floating shoulder corresponds, as defined by Goss, to a rupture of the suspensor complex. Management is not well defined but must target the proper balance between the need for anatomic restauration and quality functional results obtained in the majority of cases treated orthopaedically. This apparent paradoxical situation is probably related to the precision of indications. Material and methods: Forty-five patients managed between 1980 and 2001 were reviewed retrospectively. Thirty-five presented a scapulo-cleido-thoracic syndrome, ten a scapulocleidal syndrome. Mean age at the time of trauma was 39 years and mean follow-up was 2.4 years (1–16). The patients, 36 men and nine women were mainly (76%) traffic accident victims (58% motorcycle, 33% automobile, 9% pedestrians) and 76.8% had multiple injuries. Cleidal lesions were 18 mid-third fractures, 12 acromiocleidal dislocations, three sternocleidal dislocations, seven bifocal fracrturs, three lateral third fractures and two medial third fracturs. The scapular lesion involved the body of the bone in 19 patients, the neck in 14, the glenoid cavity in two, the coracoid process in one, and multifocal fractures in nine. Results: Thirty-two patients were treated orthopaedically and twelve patients surgically, four with cleidal osteosynthesis, eight with both. The postoperative x-rays were used to assess anatomic results and the Constant score to assess functional results. Complications included six deformed calluses, with four causing major functional impairment and one requiring revision. All resulted from orthopaedic treatments. Discussion: While most patients have an indication for orthopaedic treatment, analysis of the displacemens can lead to a surgical indication. We retained the following criteria for surgical treatment: scapular neck fracture causing more than 40° angulation, glenoid medialisation-ventralisation greater than 2 cm, and displaced articular fracture. Osteosynthesis of the clavicle for floating shoulders with a major displacement appears to be the minimum prerequisite if the multiple injuries prevent optimal management

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

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

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

We are presenting a prospective study of 25 patients with clavicle fracture treated with Rockwood Intramedullary pin fixation. Operative management is required for open fractures, neurovascular injury or compromise, displaced fractures with impending skin compromise and displaced middle third fractures with 20mm or more shortening. Plate osteosynthesis or intramedullary fixation devices are used for operative management. Patients and Methods: 25 patients with clavicle fractures underwent fixation of clavicle fractures with threaded intramedullary Rockwood pin. The indications for internal fixation were persistent wide separation of fracture with interposition of soft tissue in 12, symptomatic non-union in 3, associated multiple injuries in 3,one of them had a floating shoulder, impending open fracture with tented skin in 4 and associated acromioclavicular joint injury in 3 and one of whom had bilateral fracture clavicle.. All patients underwent open reduction through an incision centred over the fracture site along the Langer line. Intramedullary pin was inserted in a retrograde manner. Autologous bone grafting from iliac crest was done in all patients with nonunion. Radiographic and functional assessment conducted using DASH scores. Results: There were 21 male and 4 female patients with a mean age of 34 yrs (range 17 to 64 yrs). Mean follow up was 12 months (range 5 months to 30 months). Radiographic union occurred in all patients within 4 months. In our study the commonest indication for Rockwood pin fixation was displaced middle third clavicle fracture followed by impending open fractures. Commonest complication was skin irritation at the distal end of the pin with formation of a tender bursa occurring in 9 patients, 3 of whom had skin breakdown. Fracture union occurred in all these patients with no further intervention and wounds healed completely after removal of the pin. One patient developed non-union and was later treated with ORIF with DCP and bone-graft. There were no deep infections, pin breakage or migration or re-fractures after pin removal. At the time of last follow up the average DASH score was 25 with a range of 18 to 52. Conclusion: Open reduction and intramedullary fixation of clavicle fractures with Rockwood pin is a safe and effective method of treatment when surgical fixation of displaced or non-union of middle third clavicle fracture is indicated. This technique has an advantage of minimal soft tissue dissection, compression at the fracture site, less risk of migration and ease of removal, along with early return to daily and sports activities

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

Aims

The management of mid-shaft clavicle fractures (MSCFs) has evolved over the last three decades. Controversy exists over which specific fracture patterns to treat and when. This review aims to synthesize the literature in order to formulate an appropriate management algorithm for these injuries in both adolescents and adults.
