Displaced proximal Humeral fractures at Inverclyde Royal Hospital prior to 2008 were previously treated with the antegrade Acumed Polaris Proximal Humeral, predominantly in 2 part fractures. The Philos plate was introduced in 2008, initially being used to treat select non unions, and then expanded to acute fractures. The aim of this study was to assess time to union and complications in the lower volume District General setting comparing to published outcomes. From February 2008 – January 2011, 20 patients were identified. Age range 49–75 (mean 61.2) years, 8 male; 12 female. Left 9, Right 11 Neers 2 part 35%; 3 35%; 4 30%. 16 (80%) were performed in acute fractures with 4 for non-unions, 3 of which were previous polaris nail fixations. 2 patients were lost to follow up after 6/52 but were progressing well. Union was confirmed radiologically and clinically in all but 2 remaining patients (10%), one of whom suffered a significant complication of plate fracture, the second treated with revision for painful non union. 2 other significant complications were observed: transient axillary nerve palsy and deep infection. Both of these patients recovered with delayed union observed in the infection case (52 weeks). Time to union range was 8–52 weeks (mean 17.1). The literature shows a high failure rate of up to 45% with intramedullary nail fixation and limited predominantly to 2 part fractures with risk of damage to the rotator cuff. This study shows a satisfactory union rate using the Philos of 90% with only 3 (15%) requiring further surgery for non-union, plate fracture and infection. 3 and 4 part fractures composed 65% of case load. Early results indicate satisfactory outcomes compared to current published literature.
Intra-operative fluoroscopy in thumb metacarpophalangeal joint arthrodesis has been recommended as a means of achieving optimal alignment more consistently. This is not our current practice. A patient attending dissatisfied with an arthrodesis in excessive flexion performed outwith our unit highlighted the potential for problems, and we therefore elected to review our own outcomes. An evaluation of the alignment achieved in thumb metacarpophalangeal joint arthrodeses, to determine if current outcomes satisfactory or if fluoroscopic assistance should be considered. Radiological review of alignment of thumb metacarpophalangeal joint arthodeses carried out by two Consultant Surgeons with specialist interests in upper limb surgery in a District General hospital. Cases were predominantly identified retrospectively from sequential review of operating lists. The radiological images were, or had been taken, as part of routine follow-up and were not standardised. The alignment was also assessed independently by a junior doctor with no involvement in the patient's surgical treatment and no knowledge of the intended alignment. Recommended positions for arthrodesis have covered a range from 0 to 30 degrees, so for the purposes of analysis that range was considered acceptable. 14 cases had an average fusion position of 18 degrees flexion (range 6 to 30 degrees). 6 underwent concurrent ipsilaterel trapeziectomy. The series achieved satisfactory alignment radiologically without the routine use of intra-operative fluoroscopy.
