Fortunately, only a small proportion of patients with Baxter's nerve entrapment require surgery. Most people improve with an accurate diagnosis, appropriate rehabilitation, footwear modification, load management and, where indicated, treatments such as ultrasound-guided hydrodissection. Surgery is generally considered only when symptoms remain significant despite a comprehensive programme of evidence-based non-surgical care.
The most important factor before considering surgery is confidence in the diagnosis. Heel pain can arise from many different structures, and Baxter's nerve entrapment frequently exists alongside plantar fasciosis rather than occurring in isolation. If the diagnosis is uncertain, surgery should be delayed until the true source of the pain has been identified. Operating on the wrong structure is unlikely to provide a satisfactory outcome.
Before recommending surgery, I ensure that patients have undergone a thorough clinical assessment together with appropriate imaging. Diagnostic ultrasound provides valuable information about the plantar fascia and surrounding soft tissues, while MRI may be helpful when long-standing nerve compression, muscle atrophy or alternative pathology is suspected. In selected cases, a diagnostic ultrasound-guided local anaesthetic injection around Baxter's nerve may also help confirm that the nerve is the principal source of pain before considering surgery.
The goal of surgery is to decompress Baxter's nerve by relieving the structures that are compressing or tethering it. During the procedure, the surgeon carefully identifies the nerve and releases the surrounding tissues that are creating mechanical pressure. If coexisting pathology is present, such as severe plantar fascia thickening contributing to the compression, this may also need to be addressed. The exact procedure depends on the patient's anatomy and the underlying cause of the nerve irritation.
Unlike surgery for plantar fasciosis, the objective is not to release the plantar fascia simply because heel pain is present. Instead, the operation is directed specifically at relieving pressure on the nerve while preserving normal foot function as much as possible. This highlights the importance of establishing an accurate diagnosis before entering the operating theatre.
As with any surgical procedure, there are potential risks. These include infection, delayed wound healing, bleeding, scar sensitivity, persistent nerve pain, numbness, injury to nearby structures, complex regional pain syndrome and failure to achieve complete symptom relief. Although these complications are uncommon, patients should understand that surgery cannot guarantee complete resolution of symptoms.
Recovery following nerve decompression is gradual. Patients are usually encouraged to protect the surgical area during the initial healing phase before progressively increasing walking and activity. Rehabilitation remains an important part of recovery, helping restore normal movement, strength and foot function while minimising the risk of recurrent symptoms. Nerves often recover more slowly than other tissues, and improvement may continue for many months after surgery.
Published evidence regarding surgery for Baxter's nerve entrapment is encouraging but relatively limited. Most available studies are retrospective case series or observational reports rather than large randomised controlled trials. In carefully selected patients, many studies report meaningful improvements in pain and function following surgical decompression. However, the quality of the available evidence remains lower than for many other orthopaedic procedures, reinforcing the importance of careful patient selection.
One of the strongest predictors of a successful outcome is ensuring that surgery is performed for the correct reason. Patients who undergo surgery after a comprehensive assessment confirming Baxter's nerve entrapment are more likely to benefit than those who undergo surgery simply because chronic heel pain has persisted. This is another reason why persistent symptoms should always prompt a reassessment of the diagnosis rather than an automatic progression to surgery.
Surgery should therefore be viewed as the final stage in the treatment pathway rather than the first. For the majority of patients, non-surgical treatment remains effective. When surgery is required, it should form part of a carefully planned management programme based on an accurate diagnosis, realistic expectations and structured postoperative rehabilitation.
