What is a Distal Bicep

The distal bicep refers to the lower portion of the upper arm, specifically the region where the proximal biceps tendon attaches your biceps muscle to the bone, a crucial element in tendon to the bone connection. This tendon plays a crucial role in facilitating the movement of the forearm, as it connects the muscle to the top of the biceps, allowing for the transmission of forces from the muscle to the bone. The distal bicep is an essential component in the intricate system of tendons and muscles that enables the flexion and extension of the elbow joint.

Overview of Distal Biceps Tendon Ruptures

Distal biceps tendon ruptures are a relatively uncommon type of injury, accounting for approximately 3% of all biceps tendon injuries. These ruptures occur in about 1.2 individuals per 100,000 people each year. The majority of cases involve men between the ages of 40 and 50.

The injury typically happens when there is a forceful extension of the elbow while the biceps muscle is flexed. This can occur during activities such as lifting heavy objects or participating in sports that involve repetitive or sudden movements of the arm.

While non-surgical treatment may be appropriate for elderly individuals or those with a sedentary lifestyle, most patients with distal biceps tendon ruptures require surgical repair to regain full function and strength. Surgical intervention aims to reattach the torn tendon to the radial tuberosity, allowing for proper muscle function and stability.

By opting for surgical treatment for distal biceps ruptures, individuals can expect improved outcomes, enhanced muscle strength, and restored range of motion.

Surgical Approach for Distal Biceps Tendon Repair

When it comes to distal biceps tendon repair , surgeons have two primary surgical approaches to choose from: single-incision exposure or double-incision exposure. Each approach offers its own advantages and considerations.

In a single-incision approach, the surgeon performs an anterior approach through the antecubital fossa. This technique allows for direct visualization and retrieval of the biceps tendon. The single-incision exposure minimizes the potential for additional incisions and decreases the risk of complications associated with multiple incisions. This approach is particularly suitable for less complex distal biceps tears.

On the other hand, the double-incision repair involves two incisions: one in the elbow crease to retrieve the tendon and another in the dorsal region for reattachment to the radial tuberosity. This technique offers improved visualization and access to the radial tuberosity, allowing for a more secure and reliable repair. The double-incision exposure is often preferred for complex or revision cases, where additional exposure may be necessary to adequately address the injury.

During the surgical procedure, various fixation techniques can be used to secure the distal biceps tendon. Suture anchors, bone tunnels, intraosseous screw fixation, and suspensory cortical buttons are among the options available to surgeons. The choice of fixation method depends on the specific characteristics of the tendon injury and the surgeon’s preference and expertise.

Suture Anchor Placement for Distal Biceps Tendon Repair

Suture anchor placement is a crucial step in the surgical repair of distal biceps tendon ruptures. This technique involves removing a small section of periosteum over the radial tuberosity and creating pilot holes using a drill guide placed medially. The pilot holes serve as entry points for the suture anchors.

Once the pilot holes are prepared, sutures from the suture anchors are whipstitched through the distal biceps tendon. This method ensures a secure and strong fixation of the tendon to the radial tuberosity. To assess the tension of the repair, gentle pulling on the sutures is performed.

Suture anchor placement offers several advantages in distal biceps tendon repair. It allows for stable fixation, reducing the risk of failed repairs or re-ruptures. The use of suture anchors also avoids the need for drilling across the ulna or radius, which can result in cortical damage and potential complications.

To better understand the suture anchor placement technique in distal biceps tendon repair, refer to the diagram below:

Recovery and Rehabilitation After Distal Biceps Repair

Postoperative care plays a crucial role in the successful recovery and rehabilitation after distal biceps repair. Following the surgical procedure, patients will be advised to wear a posterior splint for the first week to prevent any bruising. This splint helps to immobilize the elbow and promote initial healing of the repaired tendon.

After the first week, patients will transition to a hinged elbow brace locked at 90°. This brace provides additional support and stability to the healing tendon, allowing controlled movement without putting excessive strain on the repair site.

During the initial recovery period, passive range of motion exercises will be gradually introduced. These exercises help to maintain joint mobility and prevent stiffness in the elbow. Full flexion and extension of the elbow will typically be allowed after a few weeks, under the guidance of a surgeon or physical therapist.

As the healing progresses, strengthening exercises can be initiated around the 6-week mark. These exercises aim to restore muscle strength and function in the biceps and surrounding muscles. Patients will work with a rehabilitation specialist to develop a customized exercise program that gradually increases in intensity and difficulty.

The overall recovery timeline may vary from patient to patient. While some individuals may achieve complete recovery within 3 months, others may require up to 6 months to resume normal activities. It is important for patients to follow their surgeon’s instructions and actively participate in their rehabilitation program to optimize outcomes.
