Influence of finger amputation on grip strength and objectively measured hand function
研究手指截肢的数量和水平对手功能和握力的影响，发现截肢会降低手功能（尤其是三指捏和指尖捏）和握力，其中拇指截肢影响最小，食指和III-V指截肢影响最大。
Finger amputations are common and hands are essential for functioning, but studies on factors influencing functioning after finger amputation are lacking. Therefore, we aimed to explore the influence of the number and level of amputated fingers on hand function and grip strength. A prospective descriptive cross-sectional study involving 69 patients with partial or complete amputation of one or more fingers of one hand was carried out. The function of both hands was assessed using the Southampton Hand Assessment Procedure test; grip strength was measured in 42 patients. We confirmed that finger amputation worsens hand function (especially tripod and tip pinch) and reduces grip strength, whereby the extent of the worsening depends on amputation type - it is the smallest after thumb amputation and the largest after amputation of the index finger and fingers III-V. However, because of the variety of amputation types, we recommend that future studies either involve very large samples or focus on specific amputations.
