To determine whether pre-operative cessation of anticoagulant or antiplatelet medication is necessary for patients undergoing total shoulder arthroplasty (TSA) or reverse total shoulder arthroplasty (RTSA).

A prospectively maintained database was used to identify 213 consecutive patients treated with TSA or RTSA performed by a single surgeon across 3 centres. This cohort included 24 patients on an anticoagulant agent (warfarin, apixaban, rivaroxaban, dabigatran), 52 patients on an antiplatelet agent (aspirin, clopidogrel), and a control group of 137 patients not on anticoagulant or antiplatelet medication. Patients on anticoagulant or antiplatelet medications continued these agents peri-operatively. Outcomes included haemoglobin drop, intra-operative blood loss, operative time, transfusion requirements and post-operative complications.

The mean age of the cohort was 74.3 years (range 47 – 93) and 75 (35.2%) of the patients were male. TSA was performed in 63 cases and RTSA in 150 cases. The mean haemoglobin drop in the control group was 17.3 g/L, compared to 19.3 g/L in the anticoagulant group (p = 0.20) and 15.6 g/L in the anti-platelet group (p = 0.14). The mean intra-operative blood loss in the control group was 107.8 mL, compared to 143.0 mL in the anticoagulant group (p = 0.03) and 134.3 mL in the anti-platelet group (0.02). The mean operative time in the control group was 49.3 minutes, compared to 47.1 minutes in the anticoagulant group (p = 0.56) and 50.3 minutes in the anti-platelet group (p = 0.78). Post-operatively no patients developed a wound infection or haematoma requiring intervention. Three patients not on anticoagulant or antiplatelet medication developed pulmonary embolism.

Continuing anticoagulant or antiplatelet medication was associated with higher intra-operative blood loss, but produced no statistically significant differences in haemoglobin drop, operative time, transfusion requirements or post-operative complications. We now do not routinely stop any anticoagulant or antiplatelet medication for patients undergoing total shoulder arthroplasty.

Midshaft clavicle fractures can be classified into simple or complex/comminuted. The hardest fracture to treat is the severely comminuted and displaced fracture. We retrospectively compared 286 consecutive operatively treated simple (2 and 3 part) fractures with the more complex comminuted (>=4 part) midshaft clavicle fractures, looking at outcome, complication rate and union rate.

Between 2008 and 2010 the senior author operated on 286 displaced midshaft clavicle fractures using a plate and screws. In this cohort there were 173 simple (2 and 3 part) fractures and 99 complex (>=4 part) fractures. The operation was performed through a limited incision technique and was standardized. All fractures were fixed with at least 3 screws on either side of the comminution. All patients were up until radiological and clinical union. A standardized questionnaire was used to assess patient satisfaction, return to work, sport and outcome at each postoperative visit. All complications were documented.

All fractures eventually went onto union. There were 242 males and 44 females with the average age being 33. The complex fractures had a larger scar, took longer to return to normal motion, work and sport, and took on average 10 weeks to unite compared to 6 weeks in the simple fractures. The infection rate in the simple fractures was 1% and in the complex fractures was 2%. The big difference was the incidence of non union in the complex fractures of 10% compared to 1%; the other main difference was postoperative shoulder stiffness of 3% at 3 months in the complex fractures compared to 1 % in the simple fractures. Plate elevation/irritation was also more prevalent in the complex fractures of 10% compared to 3%.

This study clearly shows there is a higher complication rate in complex fractures. Particular attention must be placed on surgical technique and anatomical reduction of these difficult fractures followed closely by postoperative rehabilitation. Future studies of clavicle fractures should specify the type of fracture being treated to give a better understanding of the potential outcome.

Introduction Unstable distal clavicle fractures have a high rate of non and delayed union, with many authors recommending surgical fixation. There are several techniques described in the literature reporting good results. We report the outcome of eighteen patients undergoing temporary fixation with a coracoclavicular screw, reinforced with Mersilene tape and Ethibond sutures.

Methods Eighteen patients were treated by a single surgeon between October 1999 and March 2003. All patients were male with an average age of 35 years. The indication for surgery was an unstable Type II fracture of the distal third clavicle. Fixation was achieved with a 6.5 mm cancellous screw through the clavicle into the coracoid process, reinforced by Mersilene tape and number 5 Ethibond sutures around the coracoid process. The arm was immobilized for two to four weeks after surgery. Each patient had the screw removed at about 11 weeks from surgery.

Results Eighteen patients achieved osseous union with painless range of motion. Union time ranged between six to 11 weeks. One patient developed a superficial skin infection, which settled with oral antibiotics, the scar required revision at time of screw removal. Two patients had screw breakage after union, which did not affect their outcome. There was no cases of screw penetration.

Conclusions This method of screw fixation is a relatively safe and easy technique of open reduction and internal fixation of the unstable distal third of clavicle. The outcome of this procedure is predictable with minimal complications.

Introduction Malunion of radial head fractures can lead to pain, stiffness and early development of osteoarthritis. While the operative management of acute displaced radial head fractures is well described there is only one published case study of treatment of radial head mal-union by an osteotomy.

Methods Four patients aged between 22 to 51 years with a displaced intra-articular radial head fracture were initially treated non-operatively in this series. They subsequently developed a malunion resulting in loss of motion and pain. Each of these cases were treated with an intra-articular osteotomy and internal fixation within two to six months of their injury. The procedure was performed via a Kochers approach, preserving the lateral ligament complex. An osteotomy was then performed through the site of malunion, with the depressed fragment being elevated, grafted and internally fixed using two compression screws to re-establish the original anatomy. In some cases a capsular release was also performed. They were followed-up for a period of six to 12 months to assess for union, range of motion and pain.

Results All patients reported a marked improvement in elbow movement with significantly reduced pain and better function. On average there was an increase of 40° of elbow flexion and 50° of forearm rotation. There was clinical and radiographic evidence of union in all cases. All four patients were satisfied with the result and were able to resume their pre-injury employment.

Conclusions Malunion of the radial head can be treated successfully by a radial head osteotomy and grafting technique as described in this paper. Each of these cases was performed within six months of the injury before arthritic change of the radiocapitellar joint was irreversible.

Introduction: Mid-shaft clavicular fractures that are displaced and shortened are often treated surgically. The standard technique in the past has been to use plate fixation. However, in the last five years intramedullary fixation has been popularised. To our knowledge no recent study has compared the outcomes of intramedullary pinning and plating of displaced mid-shaft clavicular fractures.

Method: We retrospectively evaluated 40 patients with mid-shaft clavicular fractures. Twenty patients had plate fixation and twenty patients had intramedullary fixation for exactly the same fracture pattern. Each patient filled out a standardised questionnaire particular to clavicular fractures and was assessed using the Shoulder Score Index of the American Shoulder and Elbow Surgeons and the Constant Score. A physical examination was performed and individual radiographs were assessed to determine the state of union.

Results: All fractures that were treated with intramedullary pin fixation went on to union within two to three months. There was one nonunion in the plate fixation group requiring revision surgery. The results revealed no significant difference in the functional outcome scores. There were however fewer complications, less scar related paraesthesia, shorter stay in hospital, and earlier mobilization in the group who underwent intramedullary pinning.

Conclusions: Our results suggested that both techniques of intramedullary pinning and plating resulted in good long-term functional outcomes for patients with acute mid-shaft clavicular fractures. Intramedullary pinning, however, resulted in fewer short-term complications. From this study the method of fixation for mid-shaft clavicle fractures should be determined by the surgeon’s preference and expertise.

Aim: To evaluate the usefulness of the apical oblique projection of the shoulder in determining radiographic signs of instability.

Methods: Radiographs from 50 consecutive patients who presented for surgery for treatment of symptomatic unilateral shoulder instability were evaluated. Standard radiographic views had been obtained (anteroposterior [AP], lateral and axillary view) pre-operatively along with an apical oblique. The apical oblique view is obtained by placing the patient in a 45 degrees posterior-oblique position and angling the beam 45 degrees caudad. The radiographs were reviewed independently by two radiologists. Each radiograph was evaluated for evidence of any Hill-Sachs or bony Bankart lesions that were accepted as radiographic signs of anterior instability. Comparison of the diagnostic yield of the standard views and the apical oblique were made.

Results: The radiographs of 32 males and 18 females with an average age of 27 years (range: 17 to 41 years) were included in the series. Pathology (Hill-Sachs, Bankart lesions or both) was seen on an apical oblique in 93% of cases compared with AP (48%), lateral(17%) and axillary(32%) views. Taken collectively the standard views showed pathology in only 72% of cases.

Conclusions: The apical oblique view is easy for the radiographer to obtain, can be performed using standard imaging equipment and can be obtained pain-free in the acute setting. The diagnostic yield was significantly higher than the standard trauma series. The apical oblique view should be added to these in cases of suspected shoulder instability.
