The use of robots in orthopaedic surgery is an emerging field that is gaining momentum. It has the potential for significant improvements in surgical planning, accuracy of component implantation and patient safety. Advocates of robot-assisted systems describe better patient outcomes through improved pre-operative planning and enhanced execution of surgery. However, costs, limited availability, a lack of evidence regarding the efficiency and safety of such systems and an absence of long-term high-impact studies have restricted the widespread implementation of these systems. We have reviewed the literature on the efficacy, safety and current understanding of the use of robotics in orthopaedics.

29 cases of complex elbow injuries were reviewed at a mean period of 15 months. Outcome measures included MEPS and DASH score. Patients who had defined early surgery were significantly better than those in whom surgery was delayed. We concluded that Management of complex elbow injuries can be improved by early definitive surgery. The magnitude and type of soft tissue injuries should be identified. MRI scans should be liberally used for this purpose. We believe that early, adequate and appropriate management of soft tissue injuries including use of articulated external fixator for early mobilisation improves the outcome of complex elbow injuries.

Contoured locking plates are commonly used to fix the proximal humerus fractures. Their long-term results are unknown. We present long-term radiological and functional outcome of three and four part fractures of the proximal humerus treated with PHILOS plate.

We prospectively analysed 53 consecutive three and four part proximal humerus fractures treated with PHILOS plate between 2002 and 2007. Patients were assessed using Oxford Shoulder Score and DASH score. 44 fractures (21 three part and 23 four part) were available at the final follow up.

At a mean follow-up of 8.5 years (6.4 years–10.8 years) the average Oxford Shoulder Score was 43.9 (range 23–48) and the average DASH score was 7.7 (range 0–36.7). 30% of patients required re-operation (five for hemiarthroplasty, three for impingement syndrome, five for removal of implant). Avascular necrosis (AVN) developed in 10 patients, of which only three required hemiarthroplasty. All except one patient were satisfied with the result of their operation.

Our study supports the use of locking plates for the treatment of three and four part proximal humeral fractures. In spite of some patients requiring secondary surgical intervention in the first few years, the function of the shoulder continues to improve and in the long term patients were satisfied with the outcome. An important finding of our study is that the post-traumatic AVN of humeral head does not necessarily need major surgical intervention. We believe that the possibility of avascular necrosis should not be a major determinant in the choice of surgical treatment of proximal humeral fractures.

Introduction

The purpose of this study was to assess the rate of revision subacromial decompression and identify different pathologies.

Materials/Methods

We analysed the patients who underwent Revision Arthroscopic Subacromial decompression from our prospective database of shoulder patients. Between April 2003 and Dec 2010, 797 patients underwent arthroscopic subacromial decompression. Patients who underwent any other procedure i.e. biceps tenotomy, capsular release, cuff repair were excluded from the study. Of these, 37 underwent a revision subacromial decompression (Revision rate 4.6%). The indication for revision procedure was persistent pain or restricted movements not responding to physiotherapy and injections.

Hypothesis

Recurrent shoulder dislocation is associated with bony defect of the glenoid rim, commonly seen along with bankart tear - a soft tissue injury of glenoid labrum. This cadaveric study compares the bone block effect of coracoid transfer using using two common techniques, Classical Latarjet technique and the Congruent-Arc Latarjet. We hypothesized that the force needed to dislocate the shoulder would be greater in Congruent Arc technique than the Classical Latarjet, because of increased contact surface area as a result of greater linear dimensions.

Material and methods

We dissected 14 cadaveric shoulders. A bony Bankart lesion was created in form of an inverted pear glenoid. The humeral head was attached to a pulley system that was sequentially loaded until the shoulder dislocated anteriorly. The force needed to dislocate was noted. This was repeated after coracoid transfer with two common techniques, Classical Latarjet technique and the Congruent-Arc Latarjet.
