Wallace H. Cole

Wallace H. Cole, MD (1888–1973) was an eminent twentieth-century American orthopaedic surgeon, reconstructive innovator, and academic pioneer whose transformative contributions profoundly reshaped the surgical management of complex foot and ankle deformities, pediatric musculoskeletal disorders, and acute neuromuscular rehabilitation. Globally revered for conceiving the Cole midtarsal dorsal closing wedge osteotomy for rigid pes cavus (claw-foot), formulating physiological tendon transfers to restore dynamic foot balance, and serving as the courageous scientific champion and clinical sponsor who validated Sister Elizabeth Kenny’s active mobilization method during the devastating North American poliomyelitis epidemics, Cole integrated biological conservation with meticulous operative precision. Over more than a half-century of clinical service as the long-tenured Director of Orthopedic Surgery at the University of Minnesota, the inaugural Chief Surgeon of the Twin Cities Unit of the Shriners Hospital for Crippled Children, and chief surgical leader at Gillette State Hospital, he established the American Upper Midwest as an international epicenter of orthopaedic scholarship, compassionate pediatric care, and surgical excellence.

1. The Shoulders of Giants: Historical Context & Significance

During the first half of the twentieth century, orthopaedic surgery confronted two monumental clinical crises: the recurring, terrifying onslaught of epidemic poliomyelitis and the severe, crippling deformities of the paralyzed and neuropathic extremity. Polio epidemics tore through urban centers and rural heartlands with cruel unpredictability, disproportionately striking young children and leaving thousands with asymmetric paralysis, flail limbs, and collapsing skeletal structures. The prevailing orthopaedic dogma of the 1920s and 1930s dictated prolonged, unyielding immobilization. Patients in the acute phase of infantile paralysis were routinely encased in rigid plaster casts, heavy metal splints, or cumbersome Bradford frames for months under the theoretical doctrine that paralyzed anterior horn motor cells required absolute “physiological rest.” This orthodox practice proved tragic: healthy and denervated muscle groups alike underwent rapid disuse atrophy, soft tissues contracted into unyielding fibrous bands, joint capsules underwent fibrofatty ankylosis, and young patients endured severe circulatory compromise, cutaneous ulcerations, and profound emotional terror.

“If I have seen further, it is by standing on the shoulders of giants.”

Sir Isaac Newton (1675) / Bernard of Chartres

Concurrently, the surgical management of rigid cavus foot (pes cavus or “claw-foot”)—whether precipitated by poliomyelitis, Charcot-Marie-Tooth disease, spinal dysraphism, or idiopathic neuromuscular imbalance—represented one of the most frustrating challenges in reconstructive surgery. The classical surgical answer to a rigid, high-arched foot was radical and unforgiving. Surgeons routinely performed aggressive triple arthrodeses, sacrificing the subtalar, talonavicular, and calcaneocuboid joints into a single fused osseous block. While triple arthrodesis corrected gross alignment, it completely obliterated hindfoot inversion and eversion, eliminating the foot’s vital shock-absorbing capacity and multi-axial accommodation on uneven terrain. This transformed the human foot into a rigid, jarring lever arm that accelerated painful degenerative osteoarthritis in the adjacent ankle joint. Alternatively, superficial soft tissue releases alone failed to reduce fixed skeletal contractures, condemning patients to severe metatarsalgia, intractable plantar callosities beneath depressed metatarsal heads, ulceration, and debilitating gait impairment.

Wallace H. Cole altered this historic trajectory through a rare combination of scientific humility, intellectual independence, and biomechanical ingenuity. Where entrenched academic orthodoxy saw heresy, Cole saw therapeutic truth. When an uncredentialed Australian bush nurse, Sister Elizabeth Kenny, arrived in Minneapolis in 1940 after being dismissed by eastern medical establishments, Cole refused to reject her out of hand. Opening his clinical wards at Minneapolis General Hospital and University of Minnesota Hospitals, he subjected her unconventional regimen of active mobilization, hot moist packs, and neuromuscular re-education to rigorous clinical trial, co-authoring the watershed 1941 JAMA report that dismantled the century-old dogma of rigid casting and catalyzed the birth of modern rehabilitation medicine. In the operating theater, Cole recognized that anterior pes cavus was fundamentally an apex-specific midtarsal deformity. Rather than sacrificing mobile subtalar joints, he engineered the midtarsal dorsal closing wedge osteotomy through the naviculocuneiform and cuboid bones, dropping the forefoot into a plantigrade stance while preserving essential hindfoot motion. Modern foot and ankle reconstructive surgeons, pediatric orthopaedists, and neuromuscular rehabilitation specialists stand squarely upon Wallace H. Cole’s shoulders.

2. Early Life, Formative Education & Career Milestones

Education and Formative Surgical Training

Wallace H. Cole was born in 1888 at Fort Custer, an active United States military outpost in southeastern Montana, where his father was stationed as an Army medical officer. Growing up amidst the rugged frontier garrison life instilled in him personal discipline, quiet resilience, and an early reverence for the healing arts. Relocating to Minnesota for his higher education, he matriculated at the University of Minnesota, completing his undergraduate studies before entering the University of Minnesota Medical School. He distinguished himself through exceptional anatomical precision and surgical aptitude, earning his Doctor of Medicine (MD) degree in 1910.

Committed to mastering the emerging specialty of orthopaedic surgery, Cole embarked upon an elite postgraduate training trajectory. He traveled east to Baltimore, absorbing the clinical pathology and meticulous surgical principles taught at the Johns Hopkins medical community. He then journeyed to Boston to train under Dr. Joel E. Goldthwait, one of the foundational figures of American orthopaedic surgery. Under Goldthwait’s mentorship at the Carney Hospital and Massachusetts General Hospital, Cole absorbed revolutionary concepts regarding bodily posture, spinal mechanics, pelvic stability, and tendon transposition.

Recognizing that European centers possessed the deepest traditions in bone and joint pathology, Cole undertook a trans-Atlantic fellowship to Liverpool, England, to study directly under Sir Robert Jones, the nephew of Hugh Owen Thomas and the undisputed titan of early twentieth-century British and global orthopaedic surgery. At Jones’s famed Sunday clinics at Nelson Street and the Royal Southern Hospital, Cole immersed himself in Jones’s incomparable methods of fracture reduction, joint mobilization, tendon transplantation, and functional limb alignment. Following his intensive apprenticeship in Liverpool, Cole broadened his horizons with clinical study in France and Germany, observing continental advances in aseptic operative technique, bone grafting, and orthopaedic pathology before returning to establish his surgical career in Minnesota.

Academic Appointments and Clinical Leadership

Cole’s early career was shaped by military service and wartime surgical leadership. In 1916, he served as a medical officer with the Minnesota National Guard along the Mexican border during the Pancho Villa Expedition. In May 1917, following the United States’ entry into World War I, Joel Goldthwait was commissioned by the US Surgeon General to organize an elite corps of twenty young, masterfully trained American orthopaedic surgeons to assist Sir Robert Jones in coping with the catastrophic volume of battlefield casualties in Britain. Cole was selected as one of the twenty surgeons of this storied “Goldthwait Unit.” Sailing for England, Cole worked directly alongside Jones in British military orthopaedic hospitals, treating massive compound fractures, destructive joint wounds, and peripheral nerve lacerations. He subsequently deployed to France with the American Expeditionary Forces, directing frontline orthopaedic reconstructive units and mastering surgical salvage amidst the horrors of trench warfare.

Two decades later, during the dark opening years of World War II, Cole once again answered the humanitarian call. From 1940 to 1941, prior to the official entry of the United States into the war, Dr. Cole served as the Director and Surgeon-in-Chief of the American Hospital in Britain, established at Churchill Hospital in Headington, Oxford. There, under blackout conditions and German air raids, he led surgical teams caring for severe trauma sustained by British combatants and civilian victims of the London Blitz, earning international acclaim for his clinical leadership and surgical composure.

Domestically, Cole became the preeminent orthopaedic leader of the Upper Midwest. He dedicated more than fifty years of continuous, selfless clinical service to the Gillette State Hospital for Crippled Children in St. Paul (later Gillette Children’s Specialty Healthcare), the pioneering public institution founded in 1897 by Arthur Gillette. Concurrently, when the Shriners of North America opened the Twin Cities Unit of the Shriners Hospital for Crippled Children in Minneapolis in 1923, Dr. Cole was appointed its very first Chief Surgeon. He guided the design of its clinical facilities and led its reconstructive programs for thousands of indigent children afflicted with congenital clubfoot, developmental dysplasia of the hip, tuberculosis of the spine, and post-polio paralysis.

In 1929, Dr. Cole was appointed Professor and Director of the Division of Orthopedic Surgery at the University of Minnesota Medical School, an academic chair he held with immense distinction for twenty-seven years until his retirement in 1956. Under his visionary direction, the University of Minnesota emerged as a premier center for orthopaedic education and research, fostering landmark advances in pediatric reconstruction, spinal deformity, and biomechanics.

3. Core Orthopaedic Breakthroughs, Eponymous Signs & Innovations

Wallace H. Cole’s scientific and operative legacy is defined by an enduring commitment to biological conservation and functional reconstruction. Rather than resorting to radical joint fusions or rigid immobilization, his innovations aimed to preserve native joint motion, rebalance dynamic muscle vectors, and restore physiological kinematics across complex musculoskeletal systems.

Hallmark Anatomical, Diagnostic and Operative Contributions

• The Cole Midtarsal Wedge Osteotomy (1940): In his classic 1940 treatise published in The Journal of Bone and Joint Surgery, Cole introduced a revolutionary surgical procedure for rigid anterior pes cavus. Prior to Cole’s technique, correcting a severe high-arched foot required extensive triple arthrodesis, which fused the subtalar and transverse tarsal joints and permanently abolished hindfoot motion. Cole recognized that in anterior cavus, the apex of deformity lies at the midtarsus, between the hindfoot and metatarsal bases. He devised a transverse, dorsally based wedge osteotomy through the naviculocuneiform joints medially and the cuboid bone laterally. The proximal osteotomy cut traverses the body of the navicular and the cuboid, while the distal cut traverses the three cuneiforms and the cuboid. The bone wedge is excised with a dorsal base and a plantar apex, carefully tapering to an intact or minimally disrupted plantar cortical and ligamentous hinge. When the wedge is closed, the forefoot is dorsiflexed on the hindfoot, lowering the sagittal arch and establishing a plantigrade foot. Crucially, the osteotomy spares the subtalar and calcaneocuboid/talonavicular joints, preserving essential hindfoot inversion and eversion for normal ambulation on uneven terrain.
• Tendon Transfers for Dynamic Claw-Foot (Pes Cavus) Deformity: Cole recognized that claw-foot deformities often originate from dynamic neuromuscular imbalances, such as those seen in Charcot-Marie-Tooth disease, poliomyelitis, and Friedreich’s ataxia. In these conditions, paralysis of the intrinsic foot musculature (lumbricals and interossei) allows the long toe extensors (extensor hallucis longus and extensor digitorum longus) to overpull, hyperextending the metatarsophalangeal joints and acutely depressing the metatarsal heads. Cole developed comprehensive reconstructive protocols combining radical plantar fascia release (Steindler stripping) with precise tendon transfers. By transferring the extensor hallucis longus tendon into the first metatarsal neck (Jones procedure) and transposing the long extensor tendons to the midfoot or metatarsal necks, active dorsiflexion was restored to the forefoot without clawing the toes, establishing long-term functional balance.
• Scientific Champion of the Sister Elizabeth Kenny Method (1940–1941): In 1940, Sister Elizabeth Kenny, a nurse from the Australian bush, arrived in the United States advocating an unorthodox therapy for acute poliomyelitis: abandoning rigid plaster splints, applying hot moist woolen packs to relieve muscle spasm, and initiating early passive and active-assisted range of motion. Having been rejected by medical establishments elsewhere, Kenny found an open-minded scientific champion in Wallace H. Cole. Cole, alongside Dr. Miland E. Knapp, granted her clinical facilities at Minneapolis General Hospital and University of Minnesota Hospitals. Observing her patients with rigorous scientific objectivity, Cole confirmed that early heat and mobilization dramatically decreased contractures, eliminated muscle alienation, and produced vastly superior functional recoveries. In June 1941, Cole and Knapp co-authored their landmark JAMA report, “The Kenny Treatment of Infantile Paralysis,” providing the definitive medical endorsement that transformed polio management worldwide and helped birth modern physical therapy.
• Patellar Realignment and Neoplasm Surgery (1931–1934): In his 1934 JAMA publication, “Chronic Recurrent Dislocation of the Patella,” Cole analyzed the dynamic and static stabilizers of the patellofemoral joint. He described an anatomic reconstructive approach combining extensive lateral retinacular release, medial capsular reefing, and medial transposition of the patellar tendon insertion to normalize the extensor mechanism vector (Q-angle) and prevent recurrent patellar subluxation. Furthermore, in 1931, Cole published seminal clinical series on benign bone cysts and giant cell lesions of the patella, demonstrating that thorough intra-lesional curettage and autologous bone grafting could successfully eradicate benign patellar tumors while preserving the patella and extensor mechanism continuity, preventing unnecessary patellectomy.

Biomechanical Principles: Midtarsal Kinematics, Sagittal Apex Lowering, and Joint-Sparing Reconstruction

The biomechanical foundation of Cole’s reconstructive surgery rests upon the functional anatomy of the longitudinal foot arches and the distinction between anterior and posterior cavus deformities. The longitudinal arch of the human foot comprises two interdependent columns: a flexible medial column (calcaneus, talus, navicular, medial, intermediate, and lateral cuneiforms, and the first three metatarsals) and a rigid lateral column (calcaneus, cuboid, and the fourth and fifth metatarsals). During normal gait, these columns undergo controlled reciprocal rotation around the subtalar and transverse tarsal joints to absorb impact at heel-strike and convert into a rigid lever for push-off.

In anterior pes cavus, the deformity is primarily a fixed sagittal plane equinus (plantarflexion) of the forefoot upon a normally aligned hindfoot. The sagittal apex of the deformity—the highest point of the exaggerated arch—resides at the midtarsus, specifically at the naviculocuneiform and cuboid levels. On a weight-bearing lateral radiograph, Meary’s angle (the angle between the long axis of the talus and the first metatarsal, normally 0° ± 5°) reveals a sharp dorsal apex angulation exceeding 15° to 30°, while calcaneal pitch remains normal or mildly elevated. Furthermore, the acute plantarflexion of the first metatarsal head creates a rigid tripod effect: upon weight-bearing, the first ray strikes the ground prematurely, exerting a pronatory torque across the forefoot that forces the subtalar joint into compensatory inversion, driving the calcaneus into secondary varus.

Prior to Cole’s osteotomy, surgeons addressed this deformity by performing a triple arthrodesis, excising wedges of bone from the subtalar, talonavicular, and calcaneocuboid joints. While this reduced the arch, it carried a severe biomechanical penalty: permanently destroying the 20° to 30° of normal subtalar inversion and eversion. Deprived of hindfoot motion, the foot cannot accommodate uneven surfaces, forcing the ankle joint mortise to absorb destructive shear and rotational forces, which rapidly accelerates debilitating ankle osteoarthritis.

The Cole osteotomy resolves this dilemma by executing a dorsal closing wedge osteotomy precisely at the apex of the deformity, within the midtarsus. By excising a wedge with a dorsal base and a plantar apex through the naviculocuneiform and cuboid bones, the distal forefoot rotates dorsally in the sagittal plane relative to the hindfoot. Because the osteotomy is placed distal to the talonavicular and calcaneocuboid articulations, the subtalar joint remains completely unfused and fully mobile. Closing the wedge normalizes Meary’s angle, lowers the sagittal arch, relieves excessive plantar pressure on the metatarsal heads, and eliminates the tripod torque that drives secondary heel varus. Compared to the Japas V-osteotomy (1968)—which does not excise bone but relies on depressing the midfoot fragment, often creating dorsal step-offs and risking incomplete reduction—Cole’s wedge allows precise, calibrated volumetric bone removal. By shaping the wedge asymmetrically (wider medially than laterally), the surgeon can simultaneously correct associated metatarsus adductus and frontal plane supination within a single unified procedure.

4. Master Class Pro-Tip

The successful execution of the Cole midtarsal osteotomy demands rigorous preoperative clinical assessment, meticulous wedge geometry, and strict preservation of hindfoot articular mobility.

Prior to surgery, confirm on weight-bearing lateral radiographs that the apex of cavus deformity is truly midtarsal (naviculocuneiform and cuboid level) with an abnormal Meary angle, rather than a calcaneocavus deformity driven by a high calcaneal pitch. Perform a Coleman block test to verify that hindfoot varus is flexible and driven entirely by forefoot plantarflexion; if the heel corrects to neutral on the lateral block, midfoot apex correction alone will restore a plantigrade foot without requiring a calcaneal osteotomy.

Intraoperatively, always precede the osseous cuts with a comprehensive plantar fascia release (percutaneous or open Steindler stripping) to eliminate the plantar tension band; attempting to close a dorsal midtarsal wedge against an intact, contracted plantar aponeurosis risks incomplete reduction, excessive joint compression, or fixation failure. Utilize dual dorsal incisions—medial over the naviculocuneiform joint and lateral over the cuboid—leaving a wide skin bridge of at least 4 to 5 cm. Meticulously identify and protect the dorsalis pedis artery and deep peroneal nerve in the medial interval.

Direct the proximal osteotomy cut through the navicular and cuboid, and the distal cut through the three cuneiforms and cuboid, ensuring that both cuts taper precisely to an intact or minimally breached plantar cortical and ligamentous hinge. This plantar hinge provides essential intrinsic stability and serves as a biological fulcrum during closure. Shape the dorsal wedge trapezoidally: make it 3 to 5 mm wider medially across the medial cuneiform than laterally across the cuboid to simultaneously correct associated metatarsus adductus and restore transverse tarsal collinearity, while guarding against excessive medial column shortening. Confirm plantigrade foot alignment under intraoperative fluoroscopy before achieving rigid compression with crossed cancellous screws or low-profile locking plates. Finally, inspect the toes; if extensor overdrive produces hyperextension at the metatarsophalangeal joints upon lowering the arch, perform concurrent extensor hallucis longus or extensor digitorum longus tendon transfers to prevent secondary claw toe deformities.
