Poor vision as a contributory factor in diabetic neuro-arthropathy

Limited joint mobility and plantar fascia function in Charcot's neuroarthropathy

AIM

The aim of this study was to investigate the prevalence of limited joint mobility at the first metatarsophalangeal joint (MPJ) and dysfunction of the plantar fascia in people with diabetes mellitus and Charcot's neuroarthropathy and a control group.

METHODS

Fifteen subjects with a history of mid-foot Charcot's neuroarthropathy and 26 controls with sensory neuropathy but no Charcot's neuro arthropathy were recruited. Ranges of ankle and first MPJ dorsiflexion were measured for each participant. Plantar fascia function was assessed using Jack's test.

RESULTS

The range of dorsiflexion at the first MPJ was significantly reduced in the subject group compared with the control group (51.2 vs. 64.8; P < 0.001). Jack's test demonstrated the plantar fascia to be ruptured or dysfunctional in all feet in the subject group and to be functioning in all feet in the control group.

CONCLUSIONS

It is not possible to determine from this study if the limited joint mobility at the first MPJ and dysfunction of the plantar fascia preceded or followed the development of Charcot's neuroarthropathy; however, these results are a previously unreported finding in Charcot's neuroarthropathy.

The management of neurogenic arthropathy: a tale of two charcots

The pathogenesis and natural history of Charcot neuroarthropathy is often poorly understood. The diagnosis and treatment of Charcot feet can also prove difficult. Two case histories are used to illustrate the key points in the management of this potentially devastating condition.
