Purpose: Tension band wiring is the most common surgical procedure for fixation of fractures of the Olecranon, but it is associated with high rate of metal work complications and implant failure leading to re-operation.

Method: We present a new fixation technique for olecranon fractures that avoids reoperation to remove hardware as compared with the standard fixation technique with Kirschner wires and tension band wiring as advocated by the AO technique. We describe fixation of displaced transverse and oblique olecranon fractures with anchor sutures, each of which has two pairs of suture strands. Prior to the insertion of the anchor sutures, the fracture is reduced through a standard open approach

Results: Twelve patients have been treated with this technique so far, with a mean follow-up of 6 months. The mean age of the patients was 46.7 years (range 14–75 yrs). We have followed all these patients till union of the fractures. No immediate complications have been noted. Radiographic results are good, with no loss of reduction.

Conclusion: This technique avoids the need for reop-eration for hardware removal without compromising the quality of reduction. It may be argued that anchor sutures may cost more than tension band wiring which is a very low cost procedure. At the same time, we should also consider the future cost involved because of reoperation rate and morbidity. Our newly described technique would be particularly useful in dealing with olecranon fractures in children where it is undesirable to cross the physeal plate by metal work. It would also be of great value in dealing with intra articular distal humeral fractures where fixation is planned initially but conversion to total elbow replacement becomes essential intra-operatively. In such cases an olecranon osteotomy can be fixed by this technique, even in presence of a total elbow replacement.

The aim of this study was two-fold; firstly, to investigate the construct validity of the Disability of the Arm, Shoulder and Hand (DASH) score in patients following injuries to the upper and lower limbs, and to confirm that DASH score does not measure disability solely attributed to the upper limb. Secondly, to create a modified DASH questionnaire (M2 DASH) with fewer questions that can discriminate clearly between disabilities due to problems at the upper limb, and is more specific to the upper limb.

Patients were asked to fill in the DASH questionnaire in a fracture clinic following ethical approval. This included upper limb injuries (79), lower limb injuries (61) and control subjects (52). The median DASH scores for the three groups were 57, 16 and one respectively. The DASH scores varied significantly between the three groups (Kruskal-Wallis: p< 0.001); the scores for the upper limb group were higher than the lower limb group, and the scores for the lower limb group was higher than the control group (Mann-Whitney: p< 0.001). The M2 DASH questionnaire was developed using questions specific to the upper limb and included questions 1–4, 6, 13–17, 21–23 and 26–30. The median M2 DASH scores for the three groups were 50, 7 and 0 respectively. The revised questionnaire score was then calculated for the upper limb group and a correlation study showed good correlation between the two questionnaires.

Our study shows that the original DASH questionnaire is not specific for the upper limb. This has important implications in measuring response in injuries and disease that involve both upper and lower limbs. We have devised a revised questionnaire that we suggest is referred to as M2 DASH questionnaire. The M2 DASH questionnaire has the advantage of being more specific for the upper limb than the DASH questionnaire.

Aim: Volar locking plates are increasingly used in the management of distal radius fractures. As with any new implant, understanding the rate and type of potential metalwork related complications is important. The aim of the study was to determine the type and rate of implant related complications that require further surgery when using volar locking plates in the management of distal radius fractures.

Methods: In this study, we reviewed 114 distal radius fractures treated with volar locking plating. Patient records were reviewed with regards to demographics, operative details and post-operative outcomes. Fractures were classified as intra-articular or extra-articular. They were further classified using the AO classification system

Results: In our series, 12 cases (10%) underwent further surgery for metal work related complications mainly for screw protrusion into the radiocarpal joint following fracture collapse. Intra-articular fractures had a significantly greater complication rate as compared to extra-articular ones (11 vs. 1, P=0.04). There was no significant difference between the three plating systems used in this series with regards to need of further surgery (P=0.43). There was no significant difference between the grade of the operating surgeon with regards to metal work complications (P=0.9). There was no difference in rate of complications between males and females (P=0.27). Similarly there was no difference in metal work complications between patients aged less than 60 as compared to those aged more than 60 years (P=0.58). Our study has shown that volar locking plates may be associated with up to 10% rate of metalwork complications requiring revision surgery. The most common (8 out of 12) cause of re-operation was to remove the screws protruding into the radio-carpal joint.

Discussion: Our results suggest that volar locking plates are associated with a high rate of metal work related complications requiring further surgery. In conclusion our study suggests that volar locking plates are associated with high reoperation rates for implant related complications. Intraoperative screening to ensure that there is no intrarticular penetration is also essential. We favour obtaining intra-operatively a lateral view with the forearm elevated 15–20 degrees to the horizontal plane to allow for the medial-lateral radial inclination and taking the posterior-anterior view at about 20 degrees to the horizontal plane to allow for the normal volar distal radial tilt.

We feel that for a common fracture such as distal radial fractures an ideal implant should be easily reproducible with a low complication rate.

Introduction: The Polarus nail is used in the treatment of displaced surgical neck of humerus fractures, but has been reported to have a high hardware complication rate. A recent change to 5.3 mm “non-toggling” proximal locking screws has been introduced in an attempt to minimise these complications.

The aims of this study were to determine union rates and hardware complications, and to assess whether the “non-toggle” proximal locking option prevented screw back-out.

Methods: We performed a retrospective review of case notes and radiographs of consecutive patients treated with the 150 mm length Polarus nail for acute displaced surgical neck of humerus fractures at our unit between 1st May 2002 and 29th February 2008. All patients were followed up until fracture union.

Results: Forty-nine patients were treated with the Polarus nail during the study period. Eleven patients were lost to follow-up before fracture union, so were excluded. Median age of the patients was 72 years (range: 31 to 94 years). Mean time to surgery was 10.7 days (range: two to 25 days).

Thirty-six fractures (95%) went on to unite following treatment with the Polarus nail. Of the two fractures that failed to unite one had an infective non-union and the other developed avascular necrosis with non-union of the surgical neck.

Twelve patients (32%) developed post-operative hardware complications. In nine (24%) there was backing out of the proximal locking screws, but only two patients had symptoms requiring screw removal. In five patients (13%) the nail was prominent proximally, causing impingement. In one patient (3%) the proximal screws penetrated the gleno-humeral joint, although this was asymptomatic.

There was backing-out in six of the 21 patients (29%) in which the standard 5.0 mm proximal locking screws were used. This compared with three out of 14 patients (21%) in which the 5.3 mm “non-toggling” screws were used. The difference in the rate of screw backing-out between the two groups was significant (P = 0.0474, Fisher’s Exact test). In three patients a mixture of 5.0 and 5.3 mm screws was used.

Discussion: The Polarus nail provides a stable fixation to union when used for the treatment of displaced surgical neck of humerus fractures. It is associated with a high hardware complication rate (32%), however, this is asymptomatic in the majority of cases (60%). The 5.3 mm “non-toggle” proximal locking option was found to reduce the rate of screw back-out compared with the standard 5.0 mm screw. We recommend the use of this “non-toggling” screw option for proximal locking.

We have conducted a prospective study to assess the mid-term clinical results following arthroscopic repair of the rotator cuff. Patients were evaluated using the Constant score, subjective satisfaction levels and post-operative ultrasound scans.

Of 115 consecutive patients who underwent arthroscopic repair of the rotator cuff at our institution, 102 were available for follow-up. The mean period of follow-up was for 35.8 months (24 to 73). The mean age of the patients was 57.3 years (23 to 78). There were 18 small (≤ 1 cm in diameter), 44 medium (1 cm to 3 cm in diameter), 34 large (3 cm to 5 cm in diameter) and six massive (> 5 cm in diameter) tears. There was a statistically significant increase in the size of the tear with increasing age (p = 0.0048).

The mean pre-operative Constant score was 41.4 points (95% confidence interval, 37.9 to 44.9), which improved to 84.5 (95% confidence interval, 82.2 to 86.9). A significant inverse association (p = 0.0074), was observed between the size of the tear and the post-operative Constant score, with patients having smaller tears attaining higher Constant scores after repair. Post-operatively, 80 patients (78.4%) were able to resume their occupations and 84 (82.4%) returned to their pre-injury leisure activities. Only eight (7.8%) of 102 patients were not satisfied with the outcome.

Recurrent tears were detected by ultrasound in 19 (18.6%) patients, and were generally smaller than the original ones. Patients with recurrent tears experienced a mean improvement of 31.6 points (95% confidence interval, 23.6 to 39.6) in their post-operative Constant scores. Those with intact repairs had significantly improved (p < 0.0001) Constant scores (mean improvement 46.3 points, 95% confidence interval, 41.9 to 50.6). Patient satisfaction was high in 94 cases (92%), irrespective of the outcome of the Constant score. Recurrent tears appear to be linked to age-related degeneration.

Arthroscopic repair of the rotator cuff leads to high rates of satisfaction (92%) and good functional results, albeit with a recurrence rate of 18.6% (19 of 102).

We report our experience of revision shoulder arthroplasty at Wrightington Hospital. Thirty-Nine patients had undergone revision surgery and followed up for a minimum of two years. Patients were scored using the Constant score and the ASES score pre-operatively and post operatively. All patients had X-ray evaluation for loosening and migration. Of the thirty-nine patients, 16 were failed humeral head replacement (HHR) and 16 were failed total shoulder replacement (TSR). All but two of the HHR were revised for glenoid erosion to a TSR, there was an equal proportion of patients with rheumatoid arthritis and osteoarthritis. Of the 16 patients undergoing revision surgery for failed TSR 6 were rheumatoid, 4 had osteoarthritis and 5 had posttraumatic arthritis. The main reasons for revision include glenoid loosening (7) instability (4) and peri-prosthetic fracture (2). The average constant scores post operatively for HHR and TSR were 35.5 (sd+/− 21.1) and 29.1 (sd+/− 12.1) respectively. The average ASES scores for HHR and TSR were 60.5(sd +/ 27.8) and 50.1(sd +/− 22.0) respectively. There was no statistical difference between the two groups in respect to the constant scores (p value 0.18) or ASES scores (p value 0.16). Overall, the pain relief was good post operatively following both HHR and TSR. The mean visual analogue score for pain following HHR was 3.2 and following TSR 3.5. Range of movement, function and strength was poor following both HHR and TSR.

HHR fail in a predictable way and can be revised with conversion to a TSR. TSR fail in a variety of ways and there revision surgery is demanding and complex. Both types of revision offer good pain relief but poor function.
