Analysis of functional outcome of complex forearm injuries

Background Complex forearm injuries are often associated with contamination, crushing, loss of tissues and patient arrives at odd hours when specialists are not available. These injuries can lead to complications like infective non-union, stiffness, disabilities and secondary amputations.

Methods 23 patients having complex forearm injuries treated primarily at tertiary care center by single surgeon were included in the study. Pinch strength, grip strength, residual deformity and DASH score was assessed at final follow-up. In 23 patients treated, 16 patients underwent primary internal fixation of both bone, primary external fixator was done in 4 patient, delayed fixations in 6patients, primary bone grafting in 3 patients and in 1 patient delayed bone grafting was done Skin grafting was performed in 6 cases, and flaps in 13 patients. Vascular repair was done in four patients.

Results All 23 patients came for follow-up. An average number of surgery performed per patient was 3.81 and mean hospital stay of 28.2 days. The mean duration of follow up was 47.2 months. The average DASH score was 10.24 with average key and tip pinch and grip strength of 62.24%, 58.48% and 54.75% respectively. 3 patients had superficial infection and two patient deep infections. Superficial infections were managed with IV antibiotics. The patients with nerve and vascular injuries had higher DASH score.

Conclusions Early wound coverage can improve functional outcomes. Training in plastic coverage of wounds using pedicle flaps and skin grafting, microsurgical nerve and vessel repairs for orthopedic surgeon can be of great help for the patients.
