Clavicle Fracture Repair: Operative Fixation and Postoperative Management

Surgical Decision-Making

For displaced mid-shaft clavicle fractures in adults, surgical fixation is strongly recommended as it achieves higher union rates and better early functional outcomes compared to conservative management, though both approaches yield similar long-term results 1. The key advantage of surgery is faster return to work and earlier functional recovery, which is particularly relevant for active adults 1.

When to Operate

  • Displacement with >15-20mm shortening is the primary surgical indication 2, 3
  • Fracture comminution
  • Impending skin penetration
  • Patient desire for faster recovery and return to work

Important caveat: In adolescents ≤18 years, surgery offers no benefit over conservative treatment and carries substantial revision surgery rates for implant removal 1.

Operative Fixation Technique

Choice of Implant

Either single plate fixation or intramedullary nailing produces equivalent long-term outcomes with similar complication rates 1. However:

  • Plate fixation is preferred when fracture comminution is present 1
  • Intramedullary nailing offers minimally invasive approach with smaller incisions (mean 13.9mm) 4

Plate Positioning

Anterior-inferior plating may reduce implant removal rates compared to superior plating 1, though this is based on limited evidence.

Pre-contoured anatomic clavicle plates are recommended as they demonstrate lower rates of implant removal or deformation compared to non-contoured plates 1 and provide stable fixation with mean union time of 12.8 weeks 5.

Postoperative Management

Immobilization

A simple sling is preferred over figure-of-eight bracing for immobilization 1. This is consensus-based given the absence of high-quality evidence, but slings are more comfortable and equally effective.

Duration: Typically 4 weeks of sling immobilization 4

Rehabilitation Protocol

  • Weeks 0-4: Sling immobilization with pendulum exercises
  • After 4 weeks: Progressive physiotherapy with active range of motion
  • Expected timeline: Radiographic union by 8.5-12.8 weeks 5, 3
  • Functional recovery: Significant improvement by 3 months, with excellent outcomes (Constant-Murley Score >90 or DASH score <20) by 12 months 4, 5

Antibiotic Prophylaxis

While the AAOS guidelines do not specifically address antibiotic prophylaxis for clavicle fracture fixation, standard orthopedic practice dictates:

  • Preoperative: Single dose of first-generation cephalosporin (e.g., cefazolin 2g IV) within 60 minutes of incision
  • Redosing: Every 4 hours intraoperatively if procedure exceeds this duration
  • Postoperative: Discontinue within 24 hours for clean cases

Analgesic Regimen

The guidelines do not provide specific pain management protocols. Standard practice includes:

  • Immediate postoperative: Multimodal analgesia with acetaminophen + NSAIDs (if not contraindicated)
  • Breakthrough pain: Short-acting opioids for 3-7 days as needed
  • Transition: Early transition to non-opioid regimen by 1-2 weeks

Risk Modification

Smoking cessation is critical as tobacco use increases nonunion rates and leads to inferior clinical outcomes 1. Counsel patients to stop smoking before and after surgery.

Do not use low-intensity pulsed ultrasonography (LIPUS) for acute mid-shaft clavicle fractures—it does not accelerate healing or reduce nonunion rates 1 (Moderate recommendation).

Expected Outcomes

  • Union rate: Nearly 100% with surgical fixation 4, 5, 3
  • Functional scores: 80% achieve excellent shoulder function (Constant-Murley Score >90) 5
  • Complications: Superficial infection (6.7-10%), implant irritation requiring removal (variable), no implant failure or neurovascular injury in recent series 4, 5
  • Patient satisfaction: 96% satisfaction rate with surgical treatment 3

Common Pitfalls

  • Avoid surgery in adolescents unless compelling indications exist—high revision rates for implant removal negate benefits 1
  • Consider comminution when choosing between plate and nail—plates provide better stability in comminuted fractures 1
  • Obtain upright radiographs to accurately assess displacement, as supine films may underestimate deformity 1
