Surgical Techniques of Gastrocnemius Recession and Achilles Tendon Lengthening (Descriptive Review Article)

This paper aims to review the various surgical techniques for gastrocnemius–soleus recession and Achilles tendon lengthening, with a special focus on the treatment of clubfoot and cerebral palsy (CP) equinus contracture. This descriptive review article comprehensively explores different techniques for gastrocnemius recession, including the Hoke percutaneous triple hemisection, Baker’s method (Tongue-in-Groove Gastrocnemius–Soleus Recession), the Vulpius method, the Baumann procedure, and the Strayer procedure (Gastrocnemius Recession). The objective is to present a detailed analysis of these methods, covering their indications, procedural nuances, relevance in clinical practice, and outcomes.

Finite element method based parametric study of Gastrocnemius-soleus recession: implications to the treatment of midfoot-forefoot overload syndrome

Gastrocnemius-soleus recession has been used to treat midfoot-forefoot overload syndrome and plantar fasciitis induced by equinus of the ankle joint. A controlled and selective amount of recession is imperative to maintain muscle strength and stability. The objective of this study was to conduct a parametric study to quantify the relationship between the level of recession and plantar fascia stress. A finite element model of the foot-ankle-shank complex was reconstructed from magnetic resonance and computed tomography images of a 63-year-old normal female. The model was validated by comparing modeled stresses to the measured plantar pressure distribution of the model participant during balanced standing. The midstance and push-off instants of walking stance were simulated with different levels and combinations of gastrocnemius-soleus recession resembled by different amounts of muscle forces. Halving the muscle forces at midstance reduced the average plantar fascia stress by a quarter while reducing two-third of the muscle forces at push-off reduced the average fascia stress by 18.2%. While the first ray of the plantar fascia experienced the largest stress among the five fasciae, the stress was reduced by 77.8% and 16.9% when the load was halved and reduced by two-third at midstance and push-off instants, respectively. Reduction in fascia stress implicates a lower risk of plantar fasciitis and other midfoot-forefoot overload syndromes. The outcome of this study can aid physicians to determine the amount of gastrocnemius-soleus recession towards patients with vdifferent levels of plantar fascia overstress. A detailed three-dimensional modelling on the plantar fascia is warranted in future study.

Preliminary Results of Primary Gastrocnemius-Soleus Recession for Midfoot Charcot Arthropathy.

Background Treatment of Charcot arthopathy of the foot can be challenging. The goal of this investigation was to determine whether primary gastrocnemius-soleus recession could decrease rate of new ulcers, progression of deformity, and amputation in patients with Charcot arthropathy of the midfoot.Methods A retrospective chart review revealed 28 feet in 24 diabetic patients with radiographic evidence of Charcot arthropathy of the midfoot. They were treated with primary gastrocnemius-soleus recession. Eleven feet in 11 patients had concurrent plantar midfoot ulcers. Three feet in 3 patients were lost to follow-up. Twenty-five feet in 21 patients were followed for an average of 37 months postoperatively (range = 18-79).Results A favorable outcome was defined as healing of existing ulcers, no new ulcers, no obvious progression of deformity, and no amputation. Favorable outcomes were obtained in 22 of 25 feet (18 of 21 patients). Only one patient had a persistent ulcer after gastrocnemius-soleus recession. The other 10 patients with preexisting ulcers healed. Deformity of midfoot progressed in one patient, leading ultimately to transtibial amputation. Another patient developed a knee joint infection and had a transfemoral amputation at another institution.Discussion These preliminary data suggest that primary gastrocnemius-soleus recession is followed by a much lower rate of persistent, recurrent, and new ulceration than previously reported studies. Gastrocnemius-soleus recession seems to aid in the treatment of Charcot arthropathy of the midfoot. Level IV.

Achilles Tendon Pain Treated with Gastrocnemius-Soleus Recession

The improvement in Achilles tendon pain and lack of wound complications with gastrocnemius-soleus recession compares favorably with other surgical treatments.

Orthopaedic issues in the musculoskeletal care of adults with cerebral palsy

Orthopaedic care of adults with cerebral palsy (CP) has not been well documented in orthopaedic literature. This paper focuses on some of the common problems which present themselves when adults with CP seek orthopaedic intervention. In particular, we review the most common orthopaedic issues which present to the Penn Neuro-Orthopaedics Program. A formal review of consecutive surgeries performed by the senior author on adults with CP was previously conducted. This paper focuses on the health delivery care for the adult with orthopaedic problems related to cerebral palsy. Ninety-two percent of these patients required lower extremity surgery. Forty percent had procedures performed on the upper extremities. The majority of problems seen in the Penn Neuro-Orthopaedics Program are associated with the residuals of childhood issues, particularly deformities associated with contractures. Patients are also referred for treatment of acquired musculoskeletal problems such as degenerative arthritis of the hip or knee. A combination of problems contribute most frequently to foot deformities and pain with weight-bearing, shoewear or both, most often due to equinovarus. The surgical correction of this is most often facilitated through a split anterior tibial tendon transfer. Posterior tibial transfers are rarely indicated. Residual equinus deformities contribute to a pes planus deformity. The split anterior tibial tendon transfer is usually combined with gastrocnemius-soleus recession and plantar release. Transfer of the flexor digitorum longus to the os calcis is done to augment the plantar flexor power. Rigid pes planus deformity is treated with a triple arthrodesis. Resolution of deformity allows for a good base for standing, improved ability to tolerate shoewear, and/or braces. Other recurrent or unresolved issues involve hip and knee contractures. Issues of lever arm dysfunction create problems with mechanical inefficiency. Upper extremity intervention is principally to correct contractures. Internal rotation and adductor tightness at the shoulder makes for difficult underarm hygiene and predispose a patient to a spiral fracture of the humerus. A tight flexor, pronation pattern is frequently noted through the elbow and forearm with further flexion contractures through the wrist and fingers. Lengthenings are more frequently performed than tendon transfers in the upper extremity. Arthrodesis of the wrist or on rare occasions of the metacarpal-phalangeal joints supplement the lengthenings when needed. The Penn Neuro-Orthopaedics Program has successfully treated adults with both residual and acquired musculoskeletal deformities. These deformities become more critical when combined with degenerative changes, a relative increase in body mass, fatigue, and weakness associated with the aging process.

Midfoot Ulcers Treated with Gastrocnemius-Soleus Recession

Foot ulcers in patients with neuropathy are a common cause of hospital admission for infection sometimes resulting in amputation in patients with neuropathy. Tendon lengthening alone has been reported to be successful in treating neuropathic forefoot ulcers. Tendon lengthening has also been recommended as an adjunct to bony procedures (exostectomy or fusion) for treating midfoot ulcers. The author reports the results of gastrocnemius-soleus recession as the sole treatment of diabetic midfoot ulcers. This study evaluated the results of 11 patients with 11 neuropathic plantar midfoot ulcers who were treated primarily with gastrocnemius-soleus recession with an average followup of 39 months. Potentially risky bony procedures were done after tendon lengthening if ulcers did not heal or recurred. Ten of the ulcers healed but one patient was lost to followup after his ulcer healed. One ulcer did not heal and one ulcer recurred but healed again after midfoot fusion. One patient later had a transfemoral amputation due to gangrene. Two patients later died from medical problems unrelated to their surgery. There were no incision problems, or transfer ulcers. The author believes gastrocnemius-soleus recession as a primary treatment of diabetic midfoot ulcers is a low risk method of promoting ulcer resolution.

Tibial Lengthening: Extraarticular Calcaneotibial Screw to Prevent Ankle Equinus

Between 2003 and 2006, we used an extraarticular, cannulated, fully threaded posterior calcaneotibial screw to prevent equinus contracture in 10 patients (four male and six female patients, 14 limbs) undergoing tibial lengthening with the intramedullary skeletal kinetic distractor. Diagnoses were fibular hemimelia (two), mesomelic dwarfism (two), posteromedial bow (one), hemihypertrophy (one), poliomyelitis (one), achondroplasia (one), posttraumatic limb-length discrepancy (one), and hypochondroplasia (one). Average age was 24.5 years (range, 15-54 years). The screw (length, typically 125 mm; diameter, 7 mm) was inserted with the ankle in 10 degrees dorsiflexion. Gastrocnemius soleus recession was performed in two patients to achieve 10 degrees dorsiflexion. Average lengthening was 4.9 cm (range, 3-7 cm). Screws were removed after a mean 3.3 months (range, 2-6 months). Preoperative ankle range of motion was regained within 6 months of screw removal. No neurovascular complications were encountered, and no patients experienced equinus contracture. We also conducted a cadaveric study in which one surgeon inserted screws in eight cadaveric legs under image intensifier control. The flexor hallucis longus muscle belly was the closest anatomic structure noted during dissection. The screw should be inserted obliquely from upper lateral edge of the calcaneus and aimed lateral in the tibia to avoid the flexor hallucis longus muscle. Level IV, therapeutic study.

Video-assisted gastrocnemius–soleus and hamstring lengthening in cerebral palsy patients

The aim of the study was to present the results of video-assisted fractional lengthening of the triceps surae muscle and the hamstrings in children with spastic cerebral palsy. In the period from September 2003 to December 2004, triceps surae muscle contractures were treated in 35 lower extremities (22 patients) and hamstring lengthening was performed in 12 knees (eight patients). The patients were between 4 and 10 years of age. Lengthening of the gastrocnemius-soleus was sufficient for achieving 10 degrees dorsiflexion of the foot in 31 of the 35 extremities. The short-term follow-up, at least 1 year after operation, did not reveal any complications. The hamstring lengthening resulted in full correction in nine knees; one endoscopic procedure required conversion to open surgery owing to bleeding. In one case, incomplete sciatic nerve palsy developed. Video-assisted gastrocnemius-soleus recession as well as video-assisted lengthening of the hamstrings proved to be fully efficient in the group reported here.

Gastrocnemius Soleus Recession

Multiple surgical procedures have been described for the correction of equinus deformity. We present a review of the anatomy, biomechanics, and clinical assessment of equinus. In addition, we provide a detailed surgical technique for gastrocnemius soleus recession and introduce an anatomical guide for surgical treatment.

Ankle and knee coupling in patients with spastic diplegia: effects of gastrocnemius-soleus lengthening.

Empirical observations of subjects with an equinus gait have suggested that there is coupled motion between the ankle and knee such that, during single-limb stance, the ankle moves into equinus as the knee extends. Since the gastrocnemius-soleus muscle-tendon unit spans both joints, we hypothesized that this muscle-tendon unit may be responsible for the coupling and that lengthening of the gastrocnemius-soleus muscle alone would result in greater ankle dorsiflexion as well as greater knee extension in single-limb stance, effectively uncoupling these joints. The concept that gastrocnemius-soleus lengthening may promote knee extension is counter to the popular notion that crouch gait may result if the hamstrings are not lengthened concomitantly. A retrospective review identified thirty-four subjects with specific kinematic characteristics of equinus gait, and their gait was compared with that of normal children. Of the thirty-four subjects, eleven (twenty-two limbs) subsequently underwent isolated midcalf lengthening of the gastrocnemius and soleus muscles with use of a recession technique. Gait analysis including joint kinematics and joint kinetics, electromyography, and physical examination were performed to test the hypothesis. We found that, unlike the normal subjects, the patients with an equinus gait pattern had a positive correlation (r = 0.7) between ankle and knee motion during single-limb stance. As hypothesized, ankle plantar flexion occurred while the knee moved into extension during single-limb stance. Calculations of the lengths of the gastrocnemius-soleus muscle-tendon units showed them to be short throughout the gait cycle (p < 0.0001). After gastrocnemius-soleus recession, peak ankle dorsiflexion (p < 0.001) and peak ankle power (p < 0.001) shifted to occur later in stance than they did in the preoperative gait cycle. Furthermore, the magnitude of peak power increased (p < 0.001) in late stance despite the added length of the gastrocnemius-soleus muscle-tendon unit. The electromyographic amplitude of the gastrocnemius-soleus was reduced during loading (p < 0.02), and this finding, together with the kinetic changes, suggested that muscle tension was reduced. Changes at the knee were less pronounced but included greater knee extension at foot contact (p < 0.01). No increase in the knee flexion angle or extension moment occurred in midstance after the surgery. Patients with an equinus gait pattern function with a shortened gastrocnemius-soleus muscle-tendon unit, and this results in coupled motion between the ankle and knee during single-limb stance. Lengthening, with use of a recession technique, shifted ankle power generation and dorsiflexion to a later time in stance with no tendency to increase midstance knee flexion. Knee extension did increase at foot contact, but excessive midstance knee flexion persisted and was likely due to concomitant contracture of the hamstrings.
