Investigation Reveals Hundreds of Patients Harmed in Cambridge Pediatric Surgery Scandal

Hundreds of orthopaedic patients, the vast majority of whom were children undergoing elective procedures, suffered harm while under the care of a major regional hospital, according to findings from an extensive internal investigation. The revelations have brought renewed scrutiny to long-standing oversight lapses and unheeded clinical warnings spanning more than a decade at Addenbrooke's Hospital in Cambridge.

The full scale of the surgical complications emerged inadvertently when an administrative update was mistakenly uploaded to the hospital trust’s public board papers before being abruptly taken down. The leaked document provided the public with its first comprehensive look at the severity of the clinical failures and the sheer volume of patients affected by substandard care.

According to the disclosed figures, reviewers had evaluated 924 individual cases, discovering that 209 patients had experienced direct harm as a result of their treatments. Among those affected, 47 incidents were categorized as severe, including one fatal case. Medical specialists noted that several of the injured children will never fully recover from the physical damage they sustained.

At the center of the controversy is consultant orthopaedic surgeon Kuldeep Stohr, who was formally suspended by hospital leadership in early 2025. Her suspension followed mounting internal evidence that numerous surgical procedures she performed over several years fell significantly below expected medical standards at the hospital, which functions as the primary major trauma center for the East of England.

Stohr was initially hired by Addenbrooke’s in 2012 to take up her first consultant post. Prior to her appointment at the Cambridge trust, she had completed specialized training fellowships at renowned healthcare institutions, including Great Ormond Street Hospital, the Royal National Orthopaedic Hospital, and a clinical center in New Zealand.

Despite her credentials, systemic issues regarding her surgical practice did not trigger formal operational action until 2024. During that year, Stohr took a leave of absence from her clinical duties for personal reasons, requiring other department doctors to take over the ongoing care of her surgical patients.

While reviewing her caseload, the covering clinicians identified a higher-than-expected rate of post-operative complications and raised the alarm. An initial internal review subsequently verified that at least nine pediatric procedures had been conducted well below standard operating benchmarks.

Among the early identified cases was that of Darcey, a young girl from Somersham in Cambridgeshire. In 2022, Darcey underwent surgery performed by Stohr to treat dislocating hips. Following the procedure, her parents observed that her leg would rotate inward by nearly 90 degrees whenever it lacked support, ultimately necessitating additional corrective surgery.

In the wake of these initial findings, healthcare authorities commissioned two independent investigations to examine the breakdown in care. The first inquiry, handled by the independent investigations firm Verita, examined governance failures and missed opportunities by hospital management, while a separate clinical audit was placed under the leadership of Andrew Kennedy KC.

Published in October 2025, the Verita investigation outlined a severe pattern of institutional neglect. The findings indicated that the trust's leadership had missed numerous opportunities, both major and minor, to intervene. Investigators noted that Stohr’s initial onboarding at the hospital was disorganized, leaving her with an immediate and excessive caseload paired with fragmented, remote supervision.

Verita concluded that Stohr had been systematically under-managed during her early years at the trust. The inquiry revealed that another consultant had raised formal concerns about her practice as early as 2015, citing fears that Stohr’s methods were producing poor surgical outcomes and endangering children. However, the trust failed to notify Stohr of any complaints until May 2016.

Following those early complaints, an external review was conducted in 2016 by independent expert Robert Hill, who outlined specific surgical shortcomings and recommended corrective actions. However, Hill later told the Verita inquiry that trust managers failed to draw the proper conclusions from his assessment, made no effort to consult him, and showed virtually no insight into the risks facing their patients.

Because the trust failed to act on the 2016 recommendations, deficiencies in Stohr’s technique persisted unchecked while her surgical caseload and the complexity of her patients continued to expand. Verita credited Stohr with attempting to improve her own practice based on Hill’s advice, but emphasized that she was forced to do so entirely without institutional help or supervision.

The ongoing clinical review led by Kennedy consists of ten senior consultants drawn from NHS trusts across the country. According to the mistakenly published update, the panel had conducted initial evaluations on 994 patients, with 93 percent of the case reviews fully completed ahead of the final report's expected release in November.

During a recent board meeting attended by affected families, Trust Chief Executive Nicola Ayton issued a direct apology to those impacted. Ayton apologized both for the surgical harm suffered by patients and for the distress caused by the premature public exposure of the preliminary data, promising that the completed findings will be shared directly with families before general publication.

Legal representatives working with the impacted families continue to demand accountability for the long-standing supervisory breakdown. Elizabeth Maliakal of Hudgell Solicitors, who represents several affected patients, stated that she expects the forthcoming clinical report to provide a damning assessment of the trust's governance and patient safety protocols.
