Official Description

Open treatment of ulnar shaft fracture, includes internal fixation, when performed

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

Open treatment of an ulnar shaft fracture involves a surgical procedure where the fractured bone is directly accessed and realigned. The ulna is one of the two long bones in the forearm, located on the side opposite the thumb, and the shaft refers to the long, central portion of the bone. An ulnar shaft fracture, often termed a nightstick fracture, typically occurs due to a direct impact to the ulnar side of the forearm, commonly when an individual attempts to shield themselves from a blow. This procedure includes the process of open reduction, which means that the fracture is corrected through a surgical incision rather than through closed manipulation. During the surgery, an incision is made over the fracture site, allowing the surgeon to dissect through the fascia, which is the connective tissue surrounding the muscles. The incision is strategically placed between the extensor carpi ulnaris and the flexor carpi ulnaris muscles to provide optimal access to the fracture. Once the fracture site is exposed, the periosteum, a dense layer of vascular connective tissue enveloping the bone, is incised and elevated to clear the area of any debris. The fractured bone is then realigned to its proper anatomical position, and internal fixation is applied as necessary, which often involves the use of a plate and screw device to stabilize the fracture and promote healing.

1. Indications

The open treatment of an ulnar shaft fracture is indicated in specific clinical scenarios where surgical intervention is necessary to ensure proper healing and alignment of the bone. The following conditions warrant this procedure:

  • Ulnar Shaft Fracture This procedure is performed when there is a fracture in the shaft of the ulna, which may result from trauma or injury.
  • Displacement of Fracture If the fracture is displaced, meaning the bone fragments are not aligned properly, surgical intervention is required to realign the bone.
  • Inability to Heal with Conservative Treatment When non-surgical methods, such as casting or splinting, are insufficient for healing the fracture, open treatment becomes necessary.
  • Multiple Fractures In cases where there are multiple fractures or associated injuries to the forearm, surgical treatment may be indicated to restore function and stability.

2. Procedure

The procedure for the open treatment of an ulnar shaft fracture involves several critical steps to ensure successful realignment and stabilization of the bone. The following outlines the procedural steps:

  • Step 1: Anesthesia Administration The patient is positioned appropriately, and anesthesia is administered to ensure comfort and pain management during the procedure.
  • Step 2: Incision A surgical incision is made over the fracture site, allowing access to the underlying bone. This incision is carefully planned to minimize damage to surrounding tissues.
  • Step 3: Fascia Dissection The fascia, which is the connective tissue surrounding the muscles, is dissected to expose the underlying structures. This step is crucial for gaining access to the fracture site.
  • Step 4: Exposure of the Fracture An incision is made through the fascia between the extensor carpi ulnaris and the flexor carpi ulnaris muscles. The periosteum is then incised and elevated to expose the fracture site adequately.
  • Step 5: Fracture Reduction The fracture site is cleared of any debris, and the bone fragments are carefully manipulated back into their proper alignment, a process known as reduction.
  • Step 6: Internal Fixation Once the fracture is aligned, internal fixation is applied as needed. This typically involves the use of a plate and screw device to stabilize the fracture and facilitate healing.
  • Step 7: Closure After ensuring proper alignment and fixation, the incision is closed in layers, and sterile dressings are applied to the surgical site.

3. Post-Procedure

Following the open treatment of an ulnar shaft fracture, specific post-procedure care is essential for optimal recovery. Patients are typically monitored for any signs of complications, such as infection or improper healing. Pain management is provided as needed, and the patient may be advised to keep the affected arm elevated to reduce swelling. Rehabilitation may be initiated shortly after surgery, focusing on restoring range of motion and strength in the forearm. Follow-up appointments are crucial to assess the healing process through imaging studies, and any necessary adjustments to the treatment plan can be made based on the patient's progress.

RT Right side (used to identify procedures performed on the right side of the body)
22 Increased procedural services: when the work required to provide a service is substantially greater than typically required, it may be identified by adding modifier 22 to the usual procedure code. documentation must support the substantial additional work and the reason for the additional work (ie, increased intensity, time, technical difficulty of procedure, severity of patient's condition, physical and mental effort required). note: this modifier should not be appended to an e/m service.
50 Bilateral procedure: unless otherwise identified in the listings, bilateral procedures that are performed at the same session, should be identified by adding modifier 50 to the appropriate 5 digit code. note: this modifier should not be appended to designated "add-on" codes (see appendix d).
51 Multiple procedures: when multiple procedures, other than e/m services, physical medicine and rehabilitation services or provision of supplies (eg, vaccines), are performed at the same session by the same individual, the primary procedure or service may be reported as listed. the additional procedure(s) or service(s) may be identified by appending modifier 51 to the additional procedure or service code(s). note: this modifier should not be appended to designated "add-on" codes (see appendix d).
52 Reduced services: under certain circumstances a service or procedure is partially reduced or eliminated at the discretion of the physician or other qualified health care professional. under these circumstances the service provided can be identified by its usual procedure number and the addition of modifier 52, signifying that the service is reduced. this provides a means of reporting reduced services without disturbing the identification of the basic service. note: for hospital outpatient reporting of a previously scheduled procedure/service that is partially reduced or cancelled as a result of extenuating circumstances or those that threaten the well-being of the patient prior to or after administration of anesthesia, see modifiers 73 and 74 (see modifiers approved for asc hospital outpatient use).
58 Staged or related procedure or service by the same physician or other qualified health care professional during the postoperative period: it may be necessary to indicate that the performance of a procedure or service during the postoperative period was: (a) planned or anticipated (staged); (b) more extensive than the original procedure; or (c) for therapy following a surgical procedure. this circumstance may be reported by adding modifier 58 to the staged or related procedure. note: for treatment of a problem that requires a return to the operating/procedure room (eg, unanticipated clinical condition), see modifier 78.
59 Distinct procedural service: under certain circumstances, it may be necessary to indicate that a procedure or service was distinct or independent from other non-e/m services performed on the same day. modifier 59 is used to identify procedures/services, other than e/m services, that are not normally reported together, but are appropriate under the circumstances. documentation must support a different session, different procedure or surgery, different site or organ system, separate incision/excision, separate lesion, or separate injury (or area of injury in extensive injuries) not ordinarily encountered or performed on the same day by the same individual. however, when another already established modifier is appropriate it should be used rather than modifier 59. only if no more descriptive modifier is available, and the use of modifier 59 best explains the circumstances, should modifier 59 be used. note: modifier 59 should not be appended to an e/m service. to report a separate and distinct e/m service with a non-e/m service performed on the same date, see modifier 25.
78 Unplanned return to the operating/procedure room by the same physician or other qualified health care professional following initial procedure for a related procedure during the postoperative period: it may be necessary to indicate that another procedure was performed during the postoperative period of the initial procedure (unplanned procedure following initial procedure). when this procedure is related to the first, and requires the use of an operating/procedure room, it may be reported by adding modifier 78 to the related procedure. (for repeat procedures, see modifier 76.)
79 Unrelated procedure or service by the same physician or other qualified health care professional during the postoperative period: the individual may need to indicate that the performance of a procedure or service during the postoperative period was unrelated to the original procedure. this circumstance may be reported by using modifier 79. (for repeat procedures on the same day, see modifier 76.)
80 Assistant surgeon: surgical assistant services may be identified by adding modifier 80 to the usual procedure number(s).
81 Minimum assistant surgeon: minimum surgical assistant services are identified by adding modifier 81 to the usual procedure number.
82 Assistant surgeon (when qualified resident surgeon not available): the unavailability of a qualified resident surgeon is a prerequisite for use of modifier 82 appended to the usual procedure code number(s).
