Frozen shoulder is a recognised complication following simple arthroscopic shoulder procedures, but its exact incidence has not been reported. Our aim was to analyse a single-surgeon series of patients undergoing arthroscopic subacromial decompression (ASD; group 1) or ASD in combination with arthroscopic acromioclavicular joint (ACJ) excision (group 2), to establish the incidence of frozen shoulder post-operatively. Our secondary aim was to identify associated risk factors and to compare this cohort with a group of patients with primary frozen shoulder.

We undertook a retrospective analysis of 200 consecutive procedures performed between August 2011 and November 2013. Group 1 included 96 procedures and group 2 104 procedures. Frozen shoulder was diagnosed post-operatively using the British Elbow and Shoulder Society criteria. A comparative group from the same institution involved 136 patients undergoing arthroscopic capsular release for primary idiopathic frozen shoulder.

The incidence of frozen shoulder was 5.21% in group 1 and 5.71% in group 2. Age between 46 and 60 years (p = 0.002) and a previous idiopathic contralateral frozen shoulder (p < 0.001) were statistically significant risk factors for the development of secondary frozen shoulder. Comparison of baseline characteristics against the comparator groups showed no statistically significant differences for age, gender, diabetes and previous contralateral frozen shoulder.

These results suggest that the risk of frozen shoulder following simple arthroscopic procedures is just over 5%, with no increased risk if the ACJ is also excised. Patients aged between 46 and 60 years and a previous history of frozen shoulder increase the relative risk of secondary frozen shoulder by 7.8 (95% confidence interval (CI) 2.1 to 28.3)and 18.5 (95% CI 7.4 to 46.3) respectively.

Achilles tendinopathy is characterised by chronic degeneration of the Achilles tendon, usually secondary to injury or overuse. Extracorporeal shockwave treatment (ESWT) is of potential benefit in refractory cases where conservative management with analgesia, physiotherapy and corticosteroid injection have been unsuccessful.

Patients with refractory Achilles tendinopathy enrolled between October 2010 and October 2011 received three sessions of ESWT over three weeks. Patients completed visual analogue scale (VAS) scores for pain at rest and on activity and the Victorian Institute of Sport Assessment-Achilles (VISA-A) questionnaire pre-treatment. These outcome measures and a six-point Likert satisfaction scale were reassessed at six and 16 weeks post treatment.

51 patients completed follow up. Mean age was 56 (34–80) years and mean length of symptoms 34 (4–252) months. Significant improvement (p<0.05) in VAS scores (rest and activity) and VISA-A scores was observed between baseline and 16 weeks. Mean Likert score was 3 (somewhat improved) at 16 weeks. Patients suffering Achilles tendinopathy for longer than 25 months had significantly less improvement than those affected for a shorter period.

This study suggests that ESWT improves subjective and objective outcomes in patients with refractory Achilles tendinopathy.

The treatment of nonunion is challenging providing the surgeon with a variety of different surgical options in order to encourage and achieve bone consolidation. Despite excellent results presented in 2008 of 99% union rates, Judet Osteo-Periosteal Decortication does not seem to be popular at present with bone grafting and distraction osteo-modelling being the favoured option.

Retrospective analysis was performed from December 2002 to December 2008 of 46 cases of osteoperiosteal decortication(Judet technique) for failure of fracture union.

Union was successfully achieved in 39 of the 45 patients(85%) after a mean delay of 10.7 months(range 3-39 months). Thirty patients(65%) achieved union following the decortication procedure without subsequent operations. The mean number of procedures following decortication was 0.6(range 0-4) mostly being performed for metalwork failure. Metal work failure occurred in 13 cases(28%) with the majority occurring in decortications of the femur(n=11,85%). The femur was the location of all persistent non unions in the series. The nonunion scoring system(0-100,Calori et al 2008) means were noticeably worse for the persistent nonunion group(41.67, range 34-46) compared to the union group(29, range 4-52).

Osteoperiosteal decortication remains a highly effective surgical technique in the management of failed fracture union.

Introduction: The PFNA device was developed to address problems of rotational instability in proximal femoral fractures whilst simultaneously employing a single femoral neck element.

Study Design: Prospective cohort.

Methods: All subtrochanteric fractures(AO31A3) admitted to the department were treated with the PFNA and specified data was recorded.

Results: From April 2006 to June 2007, 62 patients were included in the study.4 month follow up has been completed in 30 patients(77% of those available).11 are awaiting follow up and 12 died.The mean age was 79.9 years.

1 patient with a short PFNA nail sustained a fracture of the femur through the site of the distal locking bolt during the follow up period and required revision.

The mobility and social function scores were significantly reduced at follow up compared to pre-operative status(p=0.001).All domains of SF36 were low compared to normative data.

All 30 fractures united and there was no migration, lysis around or cut out of the helical blade.In total, 46 distal locking bolts were utilised.4 of these had migrated or become loose.

Conclusions: Subtrochanteric fractures in the elderly are a devastating injury. Patients do not return to pre-fracture function at 4 months post injury. Early results suggest that the PFNA appears to work well.
