Clavicle Osteotomy - Procedure, Recovery Guidelines, and Risks

Introduction

A clavicle fracture is common, often involving the middle part of the bone. Conservative treatment works for most cases, but displaced fractures may cause shortening and long-term issues like pain and weakness. Surgery is considered for severe cases or when nerves or blood vessels are affected. Corrective osteotomy is used for malunion cases, but it can lead to complications like broken hardware or infections. Different surgical techniques, like intramedullary fixation or plate fixation, have their pros and cons. Complications depend on factors like age, health conditions, and the severity of the fracture, so careful consideration is needed before opting for surgery.

Why Might Someone Need a Clavicle Osteotomy?

A surgical treatment called a clavicle osteotomy is used to treat shoulder problems like restricted joint movement or frequent dislocations. A curving incision is made in the collarbone to facilitate better access to the shoulder joint. This allows the surgeon to fix issues like soft tissue damage, misaligned joints, and fractured bones. Additionally, the process lessens the chance of surgical complications and minimizes muscle injury. A clavicle osteotomy may be necessary to improve shoulder function and alleviate pain or suffering associated with particular shoulder problems.

When Do Clavicle Fractures Need Surgery?

When a clavicle (collarbone) breaks, extra fragments may get lodged between the fragmented parts, or the pieces may shift around. Surgery might be required in certain situations to reassemble everything correctly. Additionally, surgery can be required if the fracture results in the collarbone becoming noticeably shorter or if the shoulder appears to droop. If surgery is the best option, or if other therapies would be more effective, an orthopedic physician with experience in shoulder injuries can check the collarbone and take X-rays.

What Are the Two Common Surgical Options for Treating a Fractured Clavicle?

There are two common options available when surgery is required for a broken collarbone:

1. Plate Fixation: To secure a metal plate to the outside of the bone, screws are used to fasten it.

2. Intramedullary Fixation: This stabilizes the bone by placing a lengthy pin into its middle.

How Is Clavicle Correction Done?

• Correction of the clavicle is done surgically using three-dimensional planning and custom guides.

• It takes three distinct orientations of the bone to realign the fractured clavicle.

• The patient can still experience pain and a malformed collarbone if it is not done correctly.

• It aids in understanding the patient's structure and deformities by specialists in three dimensions.

• It establishes the necessary amount of adjustment for a more precise surgery.

• Facilitates improved patient communication and has instructional applications.

• It requires large surgical exposure and removal of bone due to the guides being based on the shape of the bone.

• It requires using a healthy, unharmed clavicle on the opposing side, which might not always be possible.

• Extra expenses for creating and producing the guides.

• Using personalized guidelines and three-dimensional planning increases the precision of clavicle surgery.

What Are the Postoperative Recovery Guidelines?

• Since the bones are now properly aligned, pain alleviation happens quickly.

• Hospital stay is usually one night, but it varies based on the severity of the pain.

• The initial visit is one to two weeks post-surgery to evaluate the wound, remove the dressing, and track progress.

• X-rays and movement assessments will be scheduled in the 5th and 12th week following the procedure.

• Exams and X-rays are used to track the healing of the collarbone, which takes six weeks to six months of healing time.

• It typically takes one to six weeks, depending on the age, the fracture's severity, and the fixation's stability.

• If the patient wants to drive, they are usually feasible after two or three weeks.

• After surgery, patients can normally resume sports six to eight weeks later, depending on how rapidly their body heals.

• If an individual wants to return to work, physical labor could take six to eight weeks, and desk work could take a week.

• The plate can be removed only if it hurts, which is uncommon.

• Patients can gradually resume using their arms following surgery, not frequently but when in need.

• Based on plate size, scars are often kept small, ranging from 3 to 6 cm (1.2 to 2.4 inch).

What Are the Advantages and Disadvantages of the Procedures?

• Intermedullary Fixation: The incision needed for intramedullary fixation is typically smaller, and the surrounding tissues are not disturbed. But, to remove the hardware, another procedure might be required.

• Plate Fixation: The plate fixation hardware is usually left in place, although objects like backpack straps or seatbelts can occasionally irritate it. Women, in particular, make up between 10 to 15 percent of patients with plate fixation who prefer to have the hardware removed.

What Are the Risks and Complications During Clavicle Osteotomy?

• Sometimes metal plates or screws used to hold broken bones together can break or become loose.

• Infections can lead to complications and delayed healing.

• Nerve injury which leads to numbness, tingling or weakness.

• Damage to a vein or an artery that leads to bleeding or circulatory problems.

• Non-union of the bone, which requires additional treatment.

• Issues will be faced with bone healing due to factors like poor blood supply, smoking, or certain medical conditions.

• The degree of the fracture.

• Age-related factors, especially older individuals, experience slower healing and a high risk of complication.

• Malunion of the bone, which leads to deformity and dysfunction.

• Other health issues like diabetes or osteoporosis.

• Complications due to anesthesia.

• Lung injury due to factors such as prolonged immobilization or surgery.

• Bone malalignment can affect function and mobility.

• Smoking increases the risk by delaying healing.

Conclusion

Midshaft fractures make up the majority of prevalent clavicle fractures, making up around five percent of all adult fractures. Most fractures eventually end in malunion, which causes chronic discomfort, weakness, and dysfunction of the shoulder, even if nonoperative therapy works well for most of them. Since the deformity has a complex three-dimensional structure, optimal results may be difficult, even with osteotomy and other corrective surgery. Using the unaffected side of the clavicle as a reference point, recent developments in three-dimensional preoperative planning allow surgeons to visualize better and plan corrective surgeries, offering potential possibilities.
