Falanga: The clinical correlates of surgical outcomes as a result of foot whipping in a resource poor setting.

BACKGROUND

Falanga is a punishment that involves hitting the bare soles of a person's feet. The consequences of this punishment may be limb and life-threatening. Post-traumatic acute kidney injury (AKI) secondary to rhabdomyolysis is a well-documented complication. Patients often require prompt surgical intervention and renal replacement therapy (RRT). The clinical and biochemical presentation of these patients and subsequent outcomes are poorly understood.

AIMS

This prospective observational study describes the clinical presentation and effects of foot whipping on patient outcomes.

METHODOLOGY

Prospective data were collected over a one-year period for 135 patients presenting following blunt force assault admitted to a single centre. Presenting clinical characteristics and patient outcomes were recorded and correlations between presenting clinical characteristics and surgical and clinical outcomes were assessed.

RESULTS

Of 138 patients presenting following blunt force assault 96% were male with a mean age of 28.8 ± 8.01. Thirty-six out of the 138 patients presenting following blunt force assault had received foot-whipping only (falanga group, FG). Ten of these 36 patients in the FG group required surgical intervention, with one requiring a below knee amputation, compared with only two patients who required surgical intervention in the group who experienced blunt force trauma not restricted to foot whipping (Sjambok group). Average length of stay was 4 days (range 2-38) in FG group compared with 5 (range 1-21) in SG group, with no mortalities in either group. For patients in the FG, Hb was higher at presentation compared to patients in the SG group (135.2 33.7 vs 124.2 21.3, p = 0.03) and correlated positively with the need for surgical intervention (r = 0.6, p < 0.01). In this same group, the presenting characteristics of CK (4251.3 3087.4, p = 0.1 vs 7422.6 12347.7, p = 0.1) and urine output (0.95 0.4 vs 0.7 0.4) positively correlated with RRT [CK r = 0.6, p < 0.01, UO r = 0.46, p < 0.01].

CONCLUSION

Patients who present following falanga frequently require surgical intervention and the related healthcare utilisation and morbidity is high. Clinical indicators of a greater systemic injury at presentation may correlate with an increased likelihood of requiring surgical intervention or RRT.
