The authors present a retrospective study of 35 consecutive patients (60 feet) treated with the Maxwell-Brancheau Arthroereisis (MBA) implant. The mean age of the cohort at the time of surgery was 14.3 (range 5 to 46) years, and 22 (62.86%) men and 13 (37.14%) women were included. Preoperative and postoperative anteroposterior and lateral foot radiographs were compared at a mean of 36 (range 18 to 48) months postoperatively, and the following mean changes were reported: talocalcaneal angle 24.15° ± 7.97° to 18.53° ± 8.23°, calcaneocuboid angle 18.67° ± 8.72° to 11.76° ± 8.49°, first to second intermetatarsal angle 9.42° ± 2.67° to 7.61° ± 2.69°, calcaneal inclination angle 11.93° ± 6° to 14.93° ± 5.85°, and talar declination angle 34.0° ± 8.59° to 28.02° ± 6.85°; all of these differences were statistically significant (p < .0001). A subgroup of 24 (68.57%) patients also answered a subjective questionnaire at a mean of 33 (range 12 to 55) months postoperatively. The presenting chief complaints were resolved in 23 patients (95.83%) of the subgroup, and 21 patients (87.5%) returned postoperatively to either the same or a greater activity level in sports. Twenty-three (95.83% of the subgroup) patients said they were 75% to 100% satisfied with their surgical outcome, and that they would recommend the surgery to a friend or family member with the same condition, whereas 1 (4.17%) claimed 0% satisfaction after placement of inappropriately sized implants (which were later replaced to the patient's clinical satisfaction) in both feet.
作者对连续35例接受Maxwell-Brancheau关节阻滞术（MBA）植入治疗的患者（60足）进行了一项回顾性研究。该队列患者手术时的平均年龄为14.3岁（范围5至46岁），其中男性22例（62.86%），女性13例（37.14%）。术后平均36个月（范围18至48个月）时对比术前和术后足部正侧位X线片，并报告了以下平均变化：距跟角从24.15°±7.97°变为18.53°±8.23°，跟骰角从18.67°±8.72°变为11.76°±8.49°，第一与第二跖骨间角从9.42°±2.67°变为7.61°±2.69°，跟骨倾斜角从11.93°±6°变为14.93°±5.85°，距骨偏斜角从34.0°±8.59°变为28.02°±6.85°；所有这些差异均具有统计学意义（p < .0001）。24例（68.57%）患者的亚组在术后平均33个月（范围12至55个月）时还回答了一份主观问卷。该亚组中23例患者（95.83%）的主要就诊主诉得到解决，21例患者（87.5%）术后恢复到相同或更高的运动活动水平。23例患者（该亚组的95.83%）表示对手术结果满意程度为75%至100%，并表示会向患有相同病症的朋友或家人推荐该手术，而1例患者（4.17%）在双足植入尺寸不合适的植入物（后来更换至患者临床满意）后表示满意度为0%。
