In professional basketball, Jones fractures are among the most common cause of lower extremity stress injury. Despite its prevalence, there is a paucity of research on the impact of Jones fractures on athletic performance in the National Basketball Association (NBA).
To determine the impact of Jones fractures on return to play and performance among NBA players when compared with preinjury values and healthy matched controls.
Cohort study; Level of evidence, 3.
NBA injury reports were analyzed to identify 18 players who sustained a Jones fracture between 2011 and 2022. Reports were verified through public press releases, social media accounts, and player profiles. A publicly available database was used to collect player data including position, age, and years of NBA experience. Performance and advanced statistics were collected for seasons pre- and postinjury. Players were 1:1 matched with healthy controls based on age, player position, and career performance. Univariate and multivariable regression analyses were performed to compare advanced and per-game performance statistics between injured and healthy control players.
NBA players who sustained a Jones fracture had a mean age of 23.9 ± 2.31 years at the time of injury. The mean NBA experience was 3.00 ± 2.35 years and mean preinjury minutes played per game was 19.64 ± 11.24. All players (18/18) were able to return to NBA-level competition the year following the injury. There was no change in player efficiency rating (PER), value added, and estimated wins added metrics when comparing pre- and postinjury performances among injured players. Injured players missed more games ( < .001) postinjury compared with the matched controls. Multivariate analysis revealed that for players with a height of <2 m, every additional centimeter of height significantly decreased postinjury PER by 1.08 (95% CI, 0.35-1.80; < .01).
Despite its severity, most NBA players who sustain Jones fractures can return to preinjury performance and level of competition. There was no statistically significant decline in advanced statistics in the following season after injury, with a significant decrease in games played when comparing injured players with their healthy controls.
在职业篮球运动中，琼斯骨折是下肢应力性损伤最常见的原因之一。尽管其发病率很高，但关于琼斯骨折对美国职业篮球联赛（NBA）球员运动表现影响的研究却很少。
与伤前值和健康匹配对照组相比，确定琼斯骨折对NBA球员重返赛场及表现的影响。
队列研究；证据等级为3级。
分析NBA伤病报告，以确定2011年至2022年间发生琼斯骨折的18名球员。通过公开新闻稿、社交媒体账户和球员资料核实报告。使用一个公开可用的数据库收集球员数据，包括位置、年龄和NBA经验年限。收集伤前和伤后赛季的表现及高级统计数据。根据年龄、球员位置和职业表现，将球员与健康对照组进行1:1匹配。进行单变量和多变量回归分析，以比较受伤球员和健康对照球员之间的高级和每场比赛表现统计数据。
发生琼斯骨折的NBA球员受伤时的平均年龄为23.9±2.31岁。平均NBA经验为3.00±2.35年，伤前平均每场比赛上场时间为19.64±11.24分钟。所有球员（18/18）在受伤后的次年都能够重返NBA级别的比赛。在比较受伤球员伤前和伤后的表现时，球员效率值（PER）、增值和估计胜场增加指标没有变化。与匹配的对照组相比，受伤球员伤后缺席的比赛更多（P<0.001）。多变量分析显示，对于身高<2米的球员，身高每增加1厘米，伤后PER显著降低1.08（95%CI，0.35-1.80；P<0.01）。
尽管伤势严重，但大多数发生琼斯骨折的NBA球员能够恢复到伤前的表现和比赛水平。受伤后下一个赛季的高级统计数据没有统计学上的显著下降，但与健康对照组相比，受伤球员的比赛场次显著减少。
