Accessory soleus muscle as a cause of resistance to correction in congenital club foot: a case report.

A 14-month-old female with bilateral clubfeet was initially treated by serial casting and percutaneous tenotomy of the Achilles tendon, bilaterally. Both clubfeet subsequently underwent surgical treatment with a posteromedial release through a Cincinnati incision. At surgery on one clubfoot, an accessory Soleus muscle was found anterior to the Achilles tendon with a distinct insertion on the upper surface of calcaneus, anterior and medial to the insertion of Achilles tendon. This accessory Soleus muscle may have been the cause of resistance to correction in this congenital clubfoot.

Posterior tibial tendon transfer and tendo-Achilles lengthening for equinovarus foot deformity due to severe crush injury.

Surgical correction was performed on nine patients who had equinovarus deformity caused by severe crush injury of the leg sustained in an earthquake. The operative procedure used involved the transfer of the posterior tibial tendon to the dorsum of the foot by passing it through the interosseous membrane using a modified procedure as published in 1978. This procedure was combined with percutaneous Achilles tendon lengthening and tenotomy of toe flexors when needed. The average follow-up time after the operation was 21 months. The treatment improved the heel-toe steppage gait in all patients and all were able to walk in standard shoes. There were no complications in the postoperative period. Recurrence of varus deformity was not seen in any of the patients. They had active dorsiflexion of the foot, with a median active dorsiflexion of 5 degrees (0 to 10 degrees) and median active plantarflexion of 16.1 degrees (10 to 25 degrees) compared to the median active dorsiflexion and plantarflexion on the uninvolved side. The total range-of-motion was 21.1 degrees (10 to 35 degrees).

Initial pull-out strength of tendon sutures: an in vitro study in sheep Achilles tendon.

Forty-eight fresh frozen sheep Achilles tendons were used to compare the pull-out strengths of Kessler, Bunnell and locking loop techniques which are the standard configurations described for Achilles tendon repair. A simulated Achilles tendon rupture was done with a tenotomy made 2 cm proximal to the calcaneal insertion. One of the configurations was placed at the distal end of the proximal portion of the tendon specimens using No. 5 Ticron. The distal ends of the suture materials were left free and were not used to connect the proximal and distal portions of the tendon. Using a servohydraulic materials testing machine, each tendon was tested to failure in tension at a displacement rate of 20 mm/min. All the specimens failed due to pull-out of the suture material. Since the cause of failure was suture material breakage in the previous studies reporting repair strength, they were unable to represent the effect of configuration on the strength. This study is the first to represent the effect of configuration on the initial strength since there is no failure due to suture material breakage.

Operative repair of fourth and fifth toe corns.

METHODS: We report a retrospective review of 57 consecutive patients (72 feet) over a period of 20 years who had been treated operatively for either a lateral fifth toe corn or an interdigital corn of the fourth interdigital space more than two years previously. Of these, 51 patients (62 feet) returned for a follow-up evaluation at a minimum of two years (average of over seven years) which included a review of the interval history since the surgery, a physical examination, a radiographic evaluation, and assessment of the patient's satisfaction with the alignment and results of surgery. Treatment of 31 lateral fifth toe corns involved either a lateral condylectomy and flexor tenotomy or a complete condylectomy. Treatment of 31 interdigital corns comprised either a single condylectomy, double condylectomy of adjacent corns, or a complete condylectomy (hammertoe repair) of a symptomatic corn. Treatment in each case was dependent upon the severity of the deformity. RESULTS: There was found to be no significant difference in comparison of the two major groups (interdigital corns and lateral fifth toe corns) with the measurement of the relative length of the fourth and fifth metatarsals, toe malalignment, angulation of the fourth and fifth toes (MTP-4, MTP-5 angles), and the phalangeal-5 angle. Pain was relieved in 58 of 62 feet (93%) and subjective acceptable alignment was achieved in 54 of 62 feet (87%). At final follow-up 53 feet were rated by patients as excellent, seven as good, one as fair, and one as poor. Complications included numbness of the involved digit (six feet). There were two superficial infections. There were two cases of joint instability due to excessive bone resection. Joint stiffness was commonly observed (34/62 feet, 55%), but was not associated with diminished satisfaction at final follow-up. Mild asymptomatic recurrence of a callosity was noted in 10 feet and moderate or severe recurrence was noted in two feet. Dissatisfaction was associated with moderate or severe recurrence. CONCLUSION: In this retrospective study at an average of more than seven years, we achieved a high level of patient satisfaction treating both lateral fifth toe corns and interdigital corns with a partial and/or complete condylectomy, the choice depending upon the magnitude of the deformity and the callus, and the fixed nature of the lesser toe deformity.

Arthrodesis compared to Mayo resection of the first metatarsophalangeal joint in total rheumatoid forefoot reconstruction.

BACKGROUND: Painful forefoot deformity from rheumatoid arthritis can be treated with resection of the lesser metatarsal heads combined with either resection or arthrodesis of the first metatarsophalangeal (MTP) joint. METHODS: In a prospective, randomized study we compared arthrodesis of first MTP joint with Mayo resection as part of total forefoot reconstruction in patients with painful forefoot deformity from rheumatoid arthritis. The lesser metatarsal heads were resected and extensor tenotomy was done in all patients. Thirty-one patients were randomized to either the arthrodesis or resection group. RESULTS: After a mean followup of 36 (26 to 52) months, the median subjective satisfaction score was 96 points out of 100 in the resection group and 92 points in the arthrodesis group. Significant improvements in pain, handicap, and activity according to Foot Function Index (FFI) were found in both groups (p <0.001 except for handicap in resection group and activity in fusion group were p=0.02). There were no statistically significant differences between the groups in these measures, nor in the patients' willingness to have the procedure again. There were no recurrences of prominences or tenderness under the forefoot in either group and no recurrence of severe hallux valgus in the resection group. The arthrodeses healed in 93%. There was no higher risk for clinically relevant IP joint symptoms after arthrodesis. The operating time was significantly longer in the arthrodesis group but this was not linked to a higher wound infection rate. CONCLUSION: These results indicate that Mayo resection may still be a good choice for the first MTP joint in total forefoot reconstruction in patients with rheumatoid arthritis.

Giannini prosthesis for flatfoot.

BACKGROUND: To determine the clinical and radiographic results of arthroereisis using the Giannini endo-orthotic implant for the treatment of pediatric flatfoot deformity, we retrospectively evaluated 37 patients (65 feet). METHODS: Twenty-two boys and 15 girls were followed for an average of 26.5 months. Their overall average age was 9.4 (range 5 to 14) years. Pain, function, participation in sports activity, and the changes in radiographic measurements taken at 3, 6, and 12 months and then at 1-year intervals were evaluated. RESULTS: Pain or discomfort decreased from 60% (22 patients) preoperatively to 6% (2 patients) postoperatively. The percentage of normal postoperative footprints was 59% (38 feet) with first-degree flatfoot present in 27 feet (41%). Sports activities were taken up by 19 patients (51%) after surgery. An 8-mm endo-orthotic implant was used in 43 (66%) feet and an Achilles tenotomy was done in 38 feet (59%). The radiographic angles with the greatest degree of correction when compared to preoperative angles were the talar-first metatarsal angle (99%) and the calcaneal-pitch (36%). After placement of the endo-orthotic implant, the talar angle influenced the rest of the radiographic measurements. There was no postoperative deterioration in any of the radiographic angles measured during the monitoring period. Complications occurred in 10.7% of the patients, with postoperative pain being the most frequently reported (6% of patients). There was no infection or local reaction to a foreign body. Removal of the endo-orthotic implant was not done on a routine basis. CONCLUSION: This operative technique respects the anatomical structure of the foot and produces good clinical and radiographic results.

Correction of neglected clubfoot using the Ilizarov external fixator.

BACKGROUND: This study was conducted to evaluate the corrective capability of the Ilizarov external fixator in the treatment of neglected clubfoot. METHODS: Thirty patients (38 feet) with a mean age of 19 (5 to 39) years with severe deformities and stiff feet associated with neglected clubfoot were studied. A limited soft-tissue dissection, Achilles tenotomy, and plantar fasciotomy were done. Progressive correction of the deformities was achieved through a standard setting of the Ilizarov external fixator. The device was used for 16 weeks, on average, and after removal a short-leg walking cast was used for an additional 6 weeks, followed by an ankle-foot orthosis (AFO) for 6 months. RESULTS: The final outcome was scored as good (complete correction and no pain); fair (partial correction with plantigrade foot and occasional pain); or poor (nonplantigrade foot and continuous pain during walking). After a mean followup of 58 (range 12 to 107) months, the results were good in 30 feet (78.9%); fair in three feet (7.9%); and poor in five feet (13.2%). Early complications were a distal tibial fracture in one foot, dislocation of the first metatarsophalangeal joint in one foot, and arterial damage that resulted in amputation of the toes in one foot. Recurrence of the deformity was found in 19 feet (50%): 11 minor, three mild, and five severe. Spontaneous ankylosis developed in 28 feet (73.7%). Nine feet (23.7%) required arthrodesis for symptomatic arthritis of the ankle or midfoot and deformity that could not be treated with orthoses. CONCLUSION: The Ilizarov external fixator allows simultaneous correction of all the severe foot deformities associated with neglected clubfoot with minimal surgery, reducing risks of cutaneous or neurovascular complications and avoiding excessive shortening of the foot. Even in those patients in whom final corrective arthrodesis is necessary, this may be carried out with minimal bone resection, since the severe deformities of the foot and ankle have been corrected.

Peg and dowel fusion of the proximal interphalangeal joint.

The clawtoe or hammertoe deformity if frequently encountered in office practice. The etiology of this condition remains obscure, although intrinsic atrophy or imbalance was suspected as early as 1863 by Duchenne. Arthrodesing the proximal interphalangeal joint converts the more powerful flexor tendon to a flexor of the metatarsophalangeal joint, thereby alleviating pressure on the metatarsal head and distributing the weight more evenly on the forefoot. Arthrodesing is accomplished by the peg and dowel method, with the fourth toe presenting the most technical difficulties. An extensor tenotomy or dorsal capsulotomy of the metatarsophalangeal joint is frequently necessary to realign the toe with the corresponding metatarsal ray. A collodion dressing is used to immobilize the toe for a period of 4 to 6 weeks, with a fusion rate of 97% in 73 toes. All patients were contacted, with 87% responding favorably and stating that they had relief of their pain and were able to resume wearing normal footwear.

Surgery of the forepart of the foot in rheumatoid arthritis.

The purpose of this paper is to introduce a surgical approach to treatment of severe forefoot deformities of rheumatoid arthritis. Briefly, the surgery consists of base of the first metatarsal osteotomy to correct metatarsus primus varus, and metatarsal head resection beginning with the fifth metatarsal and carried around in crescentic fashion through the necks of the other metatarsals, so that as an end result the great toe is the longest, the second next to the longest, etc. The short extensor tendons are dissected to their insertions and, since they have drifted laterally into the "valleys" pulling the toes into lateral drift with them, they are usually sacrificed. The long extensor tendons are appropriately lengthened to proper tension. All the toes are straightened by plantar capsulotomies, dermotomies, and long flexor tenotomies, and the toes held straight with C-.045 wire in shishkabob fashion. Then, under direct vision, each wire is drilled up into the metatarsal shaft, aligning the toes into parallel cosmetic fashion. In the early cases, a single stem silastic implant was utilized but for the past 5 years now the double stem silastic implant is employed for the first MTP joint and is inserted "upside down" in order to give its greater power towards the floor. A cast is not used, but the patient ambulates on a well-padded bandaged foot by the second or third day. Twenty patients (40 feet) were operated upon (17 females and 3 males, ages 28 to 72 years, average 47 years), with a follow-up of 3 to 5 years. Pain relief has been remarkable. Good great toe function has been obtained in all cases with excellent power to the floor and a satisfactory range of dorsiflexion ability. About 67% have developed some mild recurrence of hallux valgus, but none so severe that it has been disabling. All patients have been pleased with their final results.

Forefoot problems in cerebral palsy-diagnosis and management.

Forefoot deformities in cerebral palsy include cavus, metatarsus adductus, hallux valgus and bunion, dorsal bunion, and toe flexion contractures. Both prevention and correction of these deformities are surgical. Some can be prevented by lengthening or tenotomy of the spastic muscle that causes the dynamic deformity which eventually becomes the fixed skeletal deformity. Fixed deformities need osteotomies and arthrodesis of the bones in addition to removing the force of the deforming muscle. Some forefoot problems are related to the mid and hind foot, e.g., hallux valgus due to spastic pes valgus. Severe cavus can develop after overzealous Achilles tendon lengthening and failure to separate forefoot from hindfoot equinus.

A biomechanical in vitro comparison of open versus percutaneous repair of tendon Achilles.

A study was undertaken to compare the in vitro strengths of percutaneous Achilles tendon repair to open Achilles tendon repair. Ten fresh frozen cadaver below-the-knee specimens underwent Achilles tenotomy. The specimens were divided into two groups of five specimens each. Group I specimens underwent open Achilles repair using a Bunnell suture technique. Group II specimens underwent percutaneous repair. Each specimen was placed on an apparatus which produced progressive ankle dorsiflexion. Measurements of anastomotic gap were correlated with angle of dorsiflexion. Group I anastomoses were able to resist almost twice the amount of ankle dorsiflexion compared to Group II anastomoses (P less than .05). Entrapment of the sural nerve occurred in three out of five specimens in Group II. Percutaneous anastomoses were malaligned in four out of five specimens. Based on this study, percutaneous repair of Achilles tendon ruptures provides approximately 50% of the initial strength afforded by open repair. Percutaneous repair places the sural nerve at risk for injury.

Rupture of the flexor hallucis longus after hallux valgus surgery: case report and comments on technique for adductor release.

A case of flexor hallucis longus (FHL) rupture following hallux valgus surgery is reported here. The authors conjecture that the FHL rupture was caused by a partial laceration of the FHL at the time of the surgical hallux valgus correction. The authors treated the painful problem by surgically debriding the distal stump of the FHL from under the first metatarsophalangeal joint (MP) and tenodesing that the proximal stump to the flexor digitorum longus (FDL). The authors describe a technique that minimizes the complications of an adductor tenotomy associated with a distal chevron type of hallux valgus correction.

Avascular necrosis of the first metatarsal head: incidence in distal osteotomy combined with lateral soft tissue release.

The incidence of avascular necrosis of the metatarsal head following distal first metatarsal osteotomy combined with adductor tendon release has not been documented in a large series of patients. Of 82 consecutive procedures in 64 patients performed between 1986 and 1988, 42 patients (58 procedures) were available for clinical and radiographic examination. Average follow-up was 2.5 years (range 1.0-4.2 years). There were 35 L-shaped and 23 chevron osteotomies which were combined with a lateral soft tissue release that included adductor tenotomy. Preoperative hallux valgus angle averaged 25 degrees (range 15-40 degrees), and intermetatarsal angle averaged 12 degrees (range 5-24 degrees). Follow-up amount of correction averaged 13 degrees and 5 degrees, respectively. Eighty-four percent of patients were satisfied with their result. There was one case of avascular necrosis. The patient was asymptomatic at 4.2 years' follow-up, and the remaining patients included two with infections, one hallux varus, and no nonunions.

Volkmann's ischemic contracture of the foot and ankle: evaluation and treatment of established deformity.

Fibrotic contracture of skeletal muscle can follow weeks or months after the severe ischemic insult of compartment syndrome. Commonly known as Volkmann's ischemic contracture, the affected limb often becomes dysfunctional and painful, and may lose sensibility. The pathogenesis of the muscle contracture includes prolonged ischemia, myonecrosis, fibroblastic proliferation, contraction of the cicatrix, and myotendinous adhesion formation. Resultant shortening or overpull of involved muscles leads to stiffness and deformity. Simultaneously, nerve injury from initial ischemia or subsequent soft tissue fibrotic compression leads to muscle paresis or paralysis of the involved compartment and of those muscles more distally innervated. The resultant deformity is thus a combination of varying degrees of contracture and weakness depending on which muscles and nerves are affected. Deformity and functional impairment in the foot and ankle secondary to ischemia are determined by many factors, including: (1) which leg compartment, if any, has been affected and to what degree extrinsic flexor or extensor overpull is exhibited, (2) degree of nerve injury sustained causing weakness or paralysis of extrinsic or intrinsic foot and ankle muscles (3) which foot compartment, if any, has been affected and to what degree intrinsic overpull is exhibited, and (4) degree of sensory nerve injury leading to anesthesia, hypoesthesia, or hyperesthesia of the foot. Therefore, a variety of clinical presentations can be encountered following compartment syndrome of the leg and foot. Treatment is based on an appreciation of the pathoanatomy of the deformity. Nonoperative therapy is aimed at obtaining or preserving joint mobility, increasing strength, and providing corrective bracing and accommodative footwear. Operative management is usually reserved for treatment of residual nerve compression or severe and problematic deformities. Established surgical protocols are performed in a stepwise fashion, to include: (1) release of residual or secondary nerve compression, (2) release of fixed contractures, using infarct excision, myotendinous lengthening, muscle recession, or tenotomy, (3) tendon transfers or arthrodesis to increase function, and (4) ostectomy or amputation for severe, refractory deformities.

Bunion correction using proximal chevron osteotomy: a single-incision technique.

Proximal chevron first metatarsal osteotomy with lateral capsulotomy, adductor tenotomy, and binding of the first and second metatarsals was reviewed in 88 consecutive cases. Seventy-two cases in 55 patients are reported, with an average clinical follow-up of 41 months. The hallux valgus angle improved an average of 15 degrees , from 32.0 degrees preoperatively to an average of 17.0 degrees postoperatively. The intermetatarsal I-II angle improved an average of 5.5 degrees, from 15.3 degrees preoperatively to 9.0 degrees postoperatively. The lateral plantar first metatarsal angle did not change. First metatarsal length was decreased by 2.0 mm. Union occurred at an average of 2 months. Sesamoid position improved 49%, from a preoperative average subluxation of 80% to a postoperative average subluxation of 29%. Subjective foot score profiles improved from a preoperative average of 70.1/100 to a postoperative average of 94.4/100 with respect to pain, deformity, motion, disability, and cosmesis. There were 10 patients with complications, including three patients with delayed unions, two with second metatarsal stress fractures, one with hallux varus, two with hallux limitus, one with progressive arthritis, one with cellulitis, and one with hallux elevatus. Eighty-four percent of the patients stated that they would undergo the procedure again without reservation, 9% would proceed with reservation, and 7% would not proceed with surgery again if offered. This technique provides reliable successful long-term results for the treatment of moderate and severe symptomatic bunion, hallux valgus, and metatarsus primus varus.

Extramuscular myofascial force transmission for in situ rat medial gastrocnemius and plantaris muscles in progressive stages of dissection.

The aim of this study was to establish the extent of extramuscular myofascial force transmission for dissected rat medial gastrocnemius (GM) and plantaris (PL) muscles. Initially, this was done with GM still connected to extramuscular connective tissue (general fascia, neuro-vascular tract and compartmental fascia). Neighbouring muscles were also connected to these tissues. In a later stage, it was dissected progressively until finally a fully dissected in situ GM was obtained, for which the neuro-vascular tract (i.e. the nerves, blood vessels and the surrounding connective tissue) was the only extramuscular tissue left intact. Force of GM was measured not only at its distal tendon in progressive stages of dissection, but also at its dissected proximal tendon. In the stage where GM was still connected to extramuscular tissues, the experiments showed that up to 40.5+/-5.9% (mean +/- S.E.M.) of the force exerted by the neighbouring PL muscle was transmitted onto the calcaneal bone, even when the PL tendon was not connected to this bone. After distal PL-tenotomy, a difference between proximally and distally measured forces of GM constituted evidence for myofascial force transmission. In the fully dissected in situ GM muscle, no relevant myofascial force transmission occurred in the reference position (the position of the GM origin corresponding to a knee angle of 120 degrees). However, some myofascial force transmission occurred when the relative position of the origin of the fully dissected GM muscle was changed with respect to the neuro-vascular tract.

Louis Stromeyer (1804-76): German orthopaedic and military surgeon and his links with Britain.

Louis Stromeyer was a pioneer of orthopaedic surgery and military medicine in Germany. The 200th anniversary of his birth was celebrated on 6 March 2004. He was much admired in Britain, which he visited on three occasions and where he met many of the country's leading surgeons. He was a friend and colleague of the London surgeon W J Little (1810-94), whose clubfoot he corrected by the operation he developed, and which Little introduced to Britain: subcutaneous tenotomy. A bibliography of Stromeyer's publications is appended.

Soft-tissue release of the hips in children with juvenile chronic arthritis.

In juvenile chronic arthritis the hips are commonly affected and this becomes the most important reason for losing independence and mobility: the joint develops a painful flexion contracture with marked loss of movement. Soft-tissue release operations consisting of psoas and adductor tenotomies have proved a safe and effective method of relieving pain and improving function. We report 89 such operations in 52 patients. More extensive soft-tissue release operations or synovectomy of the hips offer no advantage and recovery is often more painful and prolonged.
