RESUMEN
BACKGROUND: Complex regional pain syndrome type I (CRPS-I), previously known as reflex sympathetic dystrophy, is common after conservatively or surgically treated wrist fractures. Several studies support the efficacy of vitamin C in preventing CRPS-I, although the data are somewhat conflicting. The primary objective of this systematic literature review and meta-analysis was to assess the efficacy of vitamin C therapy in preventing CRPS-I after a wrist fracture. METHODS: Randomised, placebo-controlled trials of vitamin C to prevent CRPS-I after wrist fractures were sought in the three main databases: PubMed (1980 to December 2015), CENTRAL (Central 2015, number 12), and Embase (1980 to December 2015). Two authors worked independently to select articles. Data from selected articles were collected independently. RESULTS: Three randomised placebo-controlled trials in a total of 875 patients were included. Treatment was non-operative in 758/890 (85.1%) fractures and operative in 132 (14.9%) fractures. Vitamin C supplementation was started on the day of the injury and continued for 50 days. In the group given 500mg of vitamin C daily, the risk ratio for CRPS-I was 0.54 (95%CI, 0.33-0.91; P=0.02). Thus, the risk of developing CRPS-I was significantly decreased by prophylactic treatment with 500mg of vitamin C per day. The heterogeneity rate was 65% (non-significant). CONCLUSION: Daily supplementation with 500mg of vitamin C per day for 50 days decreases the 1-year risk of CRPS-I after wrist fracture. LEVEL OF EVIDENCE: II, systematic review of level I and II studies.

An 8-year-old girl sustained closed fracture of the right ulna 10 weeks prior to presentation. She was taken to a traditional bone setter who applied a tight splint. The patient reported pain, but the splint was not removed. A week after application of the splint, a foul odor was detected and removal of the splint showed extensive exposure of the forearm bones. Above elbow amputation was rejected by the patient's parents when she was taken to hospital, where she was admitted for 8 weeks by a second traditional bone setter. A trained nurse applied herbal concoctions and dressed the wound daily in anticipation that the skin would cover the exposed bone fragments. She was brought to our hospital for wound dressing so that the skin would cover the exposed bones fragments. Examination revealed a grossly shortened right forearm--by 7 cm compared with her left--extensive exposure of both radius and ulna at the anterior aspect of the forearm, and loss of sensation and movement of the fingers. Radiographs showed sequestrated radius and ulna with involucrum around the olecranon process. Above elbow amputation was offered to the patient but the parents again declined. The forearm bones detached while scrubbing the wound for review and removal of the sequestrated bone. The wound healed within one and a half weeks of dressing, resulting in an acquired boneless forearm.

STUDY DESIGN: Case report. OBJECTIVES: Patients with peripheral nerve injury may demonstrate long-lasting impairments and functional limitations. In this case report, we describe the diagnosis of a patient with a peripheral nerve injury and a conventional plan of care, along with the novel intervention of neuromuscular electrical stimulation (NMES). We feel that the additional NMES intervention was instrumental in achieving more rapid functional improvements than the more traditional interventions that are reported in the literature. BACKGROUND: The patient was a 21-year-old male who sustained a forearm fracture that was complicated by injury to the anterior interosseous branch of the median nerve. He was unable to flex the interphalangeal (IP) joint of his thumb, had decreased strength of thenar eminence musculature, and was unable to perform fine motor activities with his hand. METHODS AND MEASURES: Electrophysiological tests revealed partial denervation of the flexor pollicis longus and pronator quadratus muscles. In the fifth physical therapy session, NMES to the flexor pollicis longus and thenar muscles was added to the patient's conventional plan of care. RESULTS: With a conventional ROM and strengthening plan of care, no improvement was seen in thumb IP joint flexion over a period of 2 weeks. After 3 sessions of NMES and conventional interventions, gains in active ROM were made in thumb IP joint flexion. After 9 sessions of NMES and conventional interventions, force of thumb IP flexion was registered on a pinch dynamometer. Twenty weeks after initial examination, strength and ROM measures had improved and the patient reported no functional deficits. CONCLUSIONS: The patient showed gains in strength of the thumb IP joint after a few NMES sessions, which suggests that NMES was a helpful adjunct to the plan of care, even though the precise mechanism underlying the functional gains are not known.

Coronoid fractures have been classified into three types. Elbow instability is a well-recognized complication of type III and less so in type II fractures. Type I fractures have generally been considered to heal uneventfully, with early range of motion. We present two cases of type I fractures in athletes that failed to improve with conservative management. One developed loose body formation and the other a fibrous nonunion with mechanical blockage of elbow flexion. Both patients responded to arthroscopic intervention and returned to full athletic activities. These cases illustrate potential complications with type I coronoid fractures in competitive athletes that should be recognized and treated early.

Electromagnetic AC-stimulation according to the method of KRAUS was applied in 9 infected ununited ulnar fractures in the beagle. New cortical bone formation, bridging of the bone defect and the number of blood vessels in bone and soft tissue was assessed. Electromagnetic stimulation had no significant influence on bone healing or on the number of vessels.
