PLATING OF LATERAL END CLAVICLE FRACTURES

Abstract

Assess the outcome of plating of lateral end clavicle fractures. Lateral end clavicle fractures can be treated both conservatively and surgically. Different surgical methods are available to stabilize lateral end clavicle fractures. We treated 15 lateral end clavicle fractures with plate fixations (4 AO ‘T’ plate and 11 ACUMED lateral clavicle plate) from September 2002 to December 2005. There were 12 males and 3 females and the mean age was 33.12 year (range 23–61). 3 were done for non-union and 13 for acute fractures. 2 non-unions were treated with AO ‘T’ plate and 1 with ACUMED lateral clavicle plate. 1 patient with non-union had bone grafting at the time of the procedure. Acute fractures were stabilized with in 3 weeks from the time of the injury. All fractures were Type 2 according to Neer classification of lateral end clavicle fractures. The cause of the injury was, simple fall (3), fall from pushbike (3), assault (3), sports/skate-board (3), and RTA (3). The senior author operated on all patients. The arm was immobilized in a sling for six weeks post operatively. The follow up ranged between 5 months to 36 months All but one fracture healed. 1 ‘T’ and 1 ACUMED plate was removed 7 months after the index procedure after fracture consolidation. There was no superficial or deep infection. Patients were assessed clinically with Constant and DASH scores; patient satisfaction with the procedure was also recorded and union assessed radiologically.. Lateral end clavicle fractures pose a challenge due to the small size of the distal fragment. In our experience plating of these fractures give satisfactory results. Oblique fracture patterns result in better fixation and union rates. The plate design and advantages of the ACUMED contoured distal clavicle plates are further discussed in the paper.
