THE DEMAND OF PHALANGEAL INJURIES ON PROVISION OF A TERTIARY LEVEL HAND INJURY SERVICE AND AN OBSERVATION OF INJURY PATTERNS

Abstract

We conducted a prospective review of patients treated specifically for phalangeal fractures over a period of 6 months. Data was sourced from patient records, Emergency Dept records and theatre records. X-rays were reviewed by the senior authors using the AGFA IMPAX Web1000 v5.1 System.

A total of 654 patients presented to our hospital during the study. Of these, 257 (39%) patients were referred to the plastics and hand surgical team on-call. Remaining 397 (61%) patients were seen and treated at the local accident and emergency. Our review identified a patient group of 75 out of 654 (11.5%) patients who required operation.

• Mechanism of injury: Direct impact: n=60 (80%), Hyperextension n=11 (15%), Hyper-flexion injury n=4 (5%).

• Mode of injury: sports related, commonly rugby or football: 23 (31%) patients, crush injury 13 (17%), road traffic accident 10 (13%), punching either wall or a fellow human being in 10 (13%), fall 8 (11%), circular saw related injury in 8 (11%)

The average patient age for a phalangeal fracture was 37.3 years. 47 (63%) patients were in the age group 20–40 years. The mean age for a phalangeal fracture in males was 35.9 (16–75) years and 42.2 (23–70) years in females. The gender distribution of these patients reveals that 58/75 (77%) patients were males. This indicates that males were at an increased relative risk of 3.4 for sustaining a hand fractures than females.

The fractures were studied with respect to their complexity, digit(s) involved, phalanx and the site on the phalanx, pattern of fracture and finally the involvement of the MCP or the IP joints.

Our study revealed that fifty-two (69%) of the fractures were closed while twenty-three (31%) were open. Injuries to the distal phalanges accounted for the most of the open fractures (15/23, 67%). The little finger and the ring finger were the common fingers to be involved.

The fractures were treated with various standard techniques of operative fixation. Postoperatively patients were mobilised as soon as possible and fitted with a removable thermoplastic splint to allow daily active and passive exercises. Hand therapists followed unit protocol including at least one visit per week, with follow up for four to six weeks. Final review was undertaken by a clinician in a dedicated Hand clinic six weeks post fixation.

Our work provides data on incidence and demographic distribution of phalangeal injuries presenting acutely to an NHS Trust covering a population area of 500,000. In our trust it is standard protocol for all such injuries to be reviewed by the Hand team to institute optimal hand therapy for patients. The study enabled us to develop a patient care pathway which will improve both patient and resource management
