Chemical burns to the lower extremity can be disabling and of serious consequence if not managed properly. The severity and rapid onset of the burns caused by hydrofluoric acid after initial contact make this a highly dangerous substance. The potential severity of injury and the following complications make it a chemical of which all physicians should have a basic understanding.

Review Case Reports
Lateral subtalar dislocation: review of the literature and case presentation.
Lateral subtalar joint dislocations are rare injuries which are usually the result of a violent eversional force, driving the talar head medially and displacing the rest of the foot laterally. Associated fractures and obstruction to closed reduction are more common with lateral than medial dislocations. Avascular necrosis of the talus and navicular as well as subtalar instability may result from these injuries. ⋯ A short period of immobilization limits loss of subtalar range of motion. Open reduction may be required, particularly with entrapment of the posterior tibial tendon or obstructing fracture fragments. A case of lateral subtalar joint dislocation is presented.

Transcutaneous electrical nerve stimulation is utilized for relieving pain in the diabetes peripheral neuropathy. Previous studies were short-term and did not document sustained beneficial effects. In this study, the authors evaluated long-term effectiveness of electrotherapy administered by proprietary equipment, an H-wave machine. ⋯ The overall improvement in pain was also significant on an analog scale of 10 (p < .01), and correlated well with the percent amelioration data (r2 = .65). These data suggest an effectiveness of electrotherapy in managing neuropathic pain as an adjunct to the analgesics. It appears to provide continued benefit as the responders have used this nonpharmacological treatment modality for an average period of 1.7 +/- 0.3 years.

Comparative Study
Comparison of tension band wire and cancellous bone screw fixation for medial malleolar fractures.
A comparison study of the relative strength of tension-band fixation versus cancellous bone screw fixation of medial malleolar ankle fractures was performed on ten fresh-frozen lower limbs from five cadavers. The mean force recorded at clinical failure using cancellous screws was 60.98 N (range 33.49 to 117.86 N) compared with 129.30 N using tension-band fixation (range 85.20 to 194.64 N). Therefore, cancellous screws exhibited only 47.16% the strength of tension-band wiring at clinical failure.
