This case involves the injury threshold in a no-fault action for noneconomic damages. Plaintiff appeals as of right the order granting defendant’s motion for summary disposition. We reverse the order granting summary disposition and remand for further proceedings.
Under the no-fault act, a plaintiff may recover noneconomic losses only if the plaintiff has suffered *515 “death, serious impairment of body function, or permanent serious disfigurement.” MCL 500.3135(1).
Pursuant to MCL 500.3135(2)(a), the issue whether an individual has suffered serious impairment of body function is a question of law for the trial court to decide if the court finds either of the following:
(i) There is no factual dispute concerning the nature and extent of the person’s injuries.
(ü) There is a factual dispute concerning the nature and extent of the person’s injuries, but the dispute is not material to the determination as to whether the person has suffered a serious impairment of body function or permanent serious disfigurement.
Issues of law, as well as rulings on motions for summary disposition, are reviewed by this Court de novo.
Armstrong v Ypsilanti Charter Twp,
We read MCL 500.3135(2) as requiring a trial court to determine, as a matter of law, whether a plaintiff has suffered serious impairment of body function where there is no factual dispute, or where the facts are in dispute, but the disputed facts are not outcome-determinative with respect to a proper resolution of determining serious impairment.
Kern v Blethen-Coluni,
*516 MCL 500.3135(7) provides: “As used in this section, ‘serious impairment of body function’ means an objectively manifested impairment of an important body function that affects the person’s general ability to lead his or her normal life.”
Questions regarding statutory interpretation are reviewed de novo.
In re MCI Telecommunications Complaint,
An anchoring rule of jurisprudence, and the foremost rule of statutory construction, is that courts are to effect the intent of the Legislature. People v Wager,460 Mich 118 , 123, n 7;594 NW2d 487 (1999). To do so, we begin with an examination of the language of the statute. Wickens v Oakwood Healthcare System,465 Mich 53 , 60;631 NW2d 686 (2001). If the statute’s language is clear and unambiguous, then we assume that the Legislature intended its plain meaning and the statute is enforced as written. People v Stone,463 Mich 558 , 562;621 NW2d 702 (2001). A necessary corollary of these principles is that a court may read nothing into an unambiguous statute that is not within the manifest intent of the Legislature as derived from the words of the statute itself. Omne Financial, Inc v Shacks, Inc,460 Mich 305 , 311;596 NW2d 591 (1999).
The statutory definition of serious impairment in MCL 500.3135(7) can be broken down into three requirements that must be established in order to find *517 a serious impairment of body function. First, there must be an objectively manifested impairment. Second, the impairment must be of an important body function. Third, the impairment must affect a person’s general ability to lead his or her normal life.
The facts not being contested for purposes of determining serious impairment of body function indicate that following the motor vehicle accident, plaintiff complained of lower back, right hip, and right leg pain. Objective medical tests of plaintiff’s back indicated that plaintiff had radiculopathy, or a malfunction, of the L4 nerve root, grade one to grade two spondylolysis (arthritic like changes) between the L5 and SI locations, degenerative disc disease, and facet degenerative changes. 2 Plaintiffs doctor also found, on examination, sciatic nerve irritation in plaintiff’s right leg. The doctor noted that plaintiff had tenderness and stiffness in the lumbar region. The doctor further indicated that the L4 radiculopathy could possibly heal, but the degeneration of plaintiff’s spine is permanent. 3 A number of treatments were attempted, but plaintiff did not respond to physical therapy, he did not respond to nerve block injections, and he did not respond to pain medication. Plaintiff’s doctor advised plaintiff to avoid lifting anything over fifteen pounds and to avoid unnecessary bending and twisting. Plaintiff had worked as a carpenter for about twelve years, doing “mostly remodeling, decks, a little bit of everything; roofing, siding stuff like that.”
*518 The trial court found that plaintiffs injuries were objectively manifested on the basis of the medical examinations and tests, and that the impairment involved an important body function, thereby satisfying the first two prongs of the statutory definition of serious impairment of body function. We agree with the trial court that plaintiff established an objectively manifested impairment of an important body function on the basis of the uncontested medical evidence presented by plaintiff. 4 However, the trial court ruled that as a matter of law the impairment was not “serious enough” to impinge on plaintiffs ability to lead a normal life. This was error. The third prong of the statutory definition explicitly requires only that the impairment “a£fect[] the person’s general ability to lead his or her normal life.” 5 MCL 500.3135(7) does not require any additional proof. It would be improper for us to read any more requirements, limitations, or language into the unambiguous statutory definition. Roberts, supra at 63.
The plaintiff’s deposition testimony indicated that, after the accident, he continued to work as a carpenter, which forced him to perform some tasks that were painful, and the pain limited his time to work on a project. Plaintiff stated that he could no longer work eight hours a day but rather is limited to six hours a day, that he can no longer do roofing work, *519 that he can only do ladder work for twenty minutes at a time, that he cannot lift more than eighty pounds, that he cannot walk more than one-half mile, and that he can no longer participate in certain types of recreational hunting.
If these facts were not in dispute, we would find that they satisfy the third prong of the statutory definition, and plaintiff would be entitled to summary disposition on the issue whether he suffered a serious impairment of body function pursuant to MCL 500.3135(2)(a)(i), contrary to the trial court’s ruling. 6
For purposes of clarity on remand, we provide the following direction to the trial court. The court shall determine whether there are material issues of fact regarding plaintiff’s claims relative to the effect of the injury on his ability to work. In doing so, the court shall consider the admissibility of the videotape offered by defendant. If the court determines that there are no material factual disputes regarding plaintiff’s claimed limitations, then the court shall grant summary disposition to plaintiff on the threshold issue of serious impairment of body function. If the court determines that there are factual disputes regarding plaintiff’s claimed limitations, then the matter shall be submitted to the jury.
Eeversed and remanded for proceedings consistent with this opinion. We do not retain jurisdiction.
Notes
The Kern panel stated that “[ajbsent an outcome-determinative genuine factual dispute, the issue of threshold injury is now a question of law for the court.” Kern, supra at 341. In Kern, id. at 343-344, this Court *516 rejected the defendant’s assertion that the trial court correctly submitted the threshold determination to the jury because issues of material fact existed. This Court did not simply dispose of the issue on the basis that MCL 500.3135 no longer allowed a jury to determine serious impairment of a body function, but it instead ruled that there was no genuine issue of fact to be decided. Kern, supra at 343-344. On the basis of Kern and the plain language of MCL 500.3135(2), we can only conclude that a jury will become involved in situations where there is a material factual dispute.
Plaintiffs doctor testified that one of the most common causes for degeneration in the discs is trauma, especially in young people because degeneration typically begins at age sixty or seventy. Plaintiff was thirty-four years old at the time of the accident.
Plaintiffs doctor stated that the IA radiculopathy can be permanent, or it can be repaired, “because we’re talking about irritation to a nerve and irritation could be caused from direct or a blunt trauma to the nerve root at the time of the accident.”
The movement of one’s back is an important body function.
Shaw v Martin,
The trial court also erred in determining that this factor is objective because the factor is clearly to be determined in subjective terms.
May v Sommerfield (After Remand),
Plaintiff’s normal life consisted of, in large part, working as a carpenter. Plaintiff’s employment was not an insignificant and occasional event in his life but was instead a part of Ms normal routine. If plaintiff’s testimony is true, the impairment “affected” Ms general ability to lead Ms normal life by limiting Ms activities as a carpenter. Plaintiff’s ability to work a full eight-hour day was reduced by twenty-five percent, and he testified he could no longer accept roofing jobs. Plaintiff was allegedly further limited in performing Ms job by weight and movement restrictions.
