Clinical assessment of equinus in children before and after operation was made over a twenty-year period (1958-1978), and three groups were defined. Forty-three muscles (Group I) had abnormal shortening without spasticity and the deformity progressed steadily despite immediate improvement after operation; this was considered to be the result of a lack of muscle growth during bone growth. Forty-one muscles (Group II) had both shortening and spasticity with an imbalance which might be unchanged after operation, or reversed or improved. Fourteen muscles (Group III) had spasticity only and progression was unpredictable and could not be defined. Improvement in gait was regularly observed in Group I in the early years after operation. In Groups II and III the results were variable. These results did not depend on surgical technique but on differences in pathophysiology

1. A long-term follow-up of eighty-four patients with talipes equinovarus is reported. 2. A detailed examination was made to ascertain the nature of the residual deformity and assess the function of the deformed foot. 3. Radiographic technique in infants and adults is described. 4. Results showed that: 1) In many cases there was a dysplasia of the whole limb. 2) The dysplasia was no more marked in the patients treated in the early 1930's by multiple forceful under anaesthetic, than in the more recent patients treated by gentler means. 3) Nearly half the cases had only a false correction of the deformity in that the foot was "broken" at the talo-navicular level, leaving the heel in inversion, although the forefoot was plantigrade. 5. The posture of patients with laterally rotated hip joints is related to the fixed inverted heel. 6. Clinical assessment correlated with radiographic appearances shows clearly the near impossibility of a good foot resulting from a false correction

We report a randomised prospective trial of the early results of three types of treatment for displaced intracapsular hip fractures. We used a questionnaire sent to patients at about six months (Nottingham Health Profile, NHP) in addition to clinical assessments. There was a 67.4% usable response to the questionnaire, similar to that in other studies using the NHP. There were more responders from younger patients, those walking independently before injury and those with higher mental test scores on admission. In the younger group (65 to 79 years) we found a trend for better scores in most NHP indices after the use of a bipolar prosthesis rather than a unipolar prosthesis or internal fixation, particularly for social function, pain and physical mobility. Postal assessment using the NHP gave a satisfactory response rate even in the elderly, and can provide an extra assessment to complement or replace hospital follow-up in some circumstances

Aims

A retrospective longitudinal study was conducted to compare directly volumetric wear of retrieved polyethylene inserts to predicted volumetric wear modelled from individual gait mechanics of total knee arthroplasty (TKA) patients.

Since 1986, we have treated displaced intra-articular fractures of the calcaneum by open reduction through a lateral approach, stable internal fixation and bone grafting. We assessed the results at a mean follow-up of 2.92 years in 44 patients, comparing them with those for 19 patients treated non-operatively. Clinical assessment used the scoring system of Crosby and Fitzgibbons (1990) and radiological measurements were made from lateral, axial and internal oblique views. The articular congruity of the subtalar joint and any arthritic changes were also assessed. We found significantly better results in the operated group with respect to pain, activity, range of movement, return to work and swelling of the hind foot. Radiologically, the operated group showed significantly better scores for articular congruity and arthritic changes. We conclude that the operative treatment of displaced intra-articular fractures of the calcaneum gives better medium-term results than conservative management

The aim of this study was to define objectively gait function in children with treated congenital talipes equinovarus (CTEV) and a good clinical result. The study also attempted an analysis of movement within the foot during gait. We compared 20 children with treated CTEV with 15 control subjects. Clinical assessment demonstrated good results from treatment. Three-dimensional gait analysis provided kinematic and kinetic data describing movement and moments at the joints of the lower limb during gait. A new method was used to study movement within the foot during gait. The data on gait showed significantly increased internal rotation of the foot during walking which was partially compensated for by external rotation at the hip. A mild foot drop and reduced plantar flexor power were also observed. Dorsiflexion at the midfoot was significantly increased, which probably compensated for reduced mobility at the hindfoot. Patients treated for CTEV with a good clinical result should be expected to have nearly normal gait and dynamic foot movement, but there may be residual intoeing, mild foot drop, loss of plantar flexor power with compensatory increased midfoot dorsiflexion and external hip rotation

1. The end-results of conservative treatment of supraspinatus tears have been studied in a series of 109 patients graded on a clinical basis, and in a further series of twenty-seven patients assessed initially by procaine infiltration. 2. In 87 per cent. of patients with mild lesions, full function was regained in an average period of five and a half weeks. In more than 50 per cent. of patients with apparently severe lesions, there was full functional recovery in eleven to thirteen weeks. 3. Clinical assessment, other than as mild or apparently severe, is unreliable in the early stages. 4. Procaine infiltration of recent tears, by abolishing pain and spasm, allows more accurate assessment of supraspinatus function and gives a more clear indication as to the advisability of conservative or early operative treatment. If such infiltration of the torn segment of tendon fails to restore voluntary abduction power, early operative repair is indicated. 5. Six patients with negative procaine tests, in whom the shoulder cuff was subsequently explored, all showed extensive tears

The COVID-19 pandemic has disrupted all segments of daily life, with the healthcare sector being at the forefront of this upheaval. Unprecedented efforts have been taken worldwide to curb this ongoing global catastrophe that has already resulted in many fatalities. One of the areas that has received little attention amid this turmoil is the disruption to trainee education, particularly in specialties that involve acquisition of procedural skills. Hand surgery in Singapore is a standalone combined programme that relies heavily on dedicated cross-hospital rotations, an extensive didactic curriculum and supervised hands-on training of increasing complexity. All aspects of this training programme have been affected because of the cancellation of elective surgical procedures, suspension of cross-hospital rotations, redeployment of residents, and an unsustainable duty roster. There is a real concern that trainees will not be able to meet their training requirements and suffer serious issues like burnout and depression. The long-term impact of suspending training indefinitely is a severe disruption of essential medical services. This article examines the impact of a global pandemic on trainee education in a demanding surgical speciality. We have outlined strategies to maintain trainee competencies based on the following considerations: 1) the safety and wellbeing of trainees is paramount; 2) resource utilization must be thoroughly rationalized; 3) technology and innovative learning methods must supplant traditional teaching methods; and 4) the changes implemented must be sustainable. We hope that these lessons will be valuable to other training programs struggling to deliver quality education to their trainees, even as we work together to battle this global catastrophe.

Aims

The aim was to compare long-term patient-reported outcome measures (PROMs) after operative and nonoperative treatment of acute Achilles tendon rupture in the context of a randomized controlled trial.

We performed a prospective genotype-phenotype study using molecular screening and clinical assessment to compare the severity of disease and the risk of sarcoma in 172 individuals (78 families) with hereditary multiple exostoses. We calculated the severity of disease including stature, number of exostoses, number of surgical procedures that were necessary, deformity and functional parameters and used molecular techniques to identify the genetic mutations in affected individuals. Each arm of the genotype-phenotype study was blind to the outcome of the other. Mutations EXT1 and EXT2 were almost equally common, and were identified in 83% of individuals. Non-parametric statistical tests were used. There was a wide variation in the severity of disease. Children under ten years of age had fewer exostoses, consistent with the known age-related penetrance of this condition. The severity of the disease did not differ significantly with gender and was very variable within any given family. The sites of mutation affected the severity of disease with patients with EXT1 mutations having a significantly worse condition than those with EXT2 mutations in three of five parameters of severity (stature, deformity and functional parameters). A single sarcoma developed in an EXT2 mutation carrier, compared with seven in EXT1 mutation carriers. There was no evidence that sarcomas arose more commonly in families in whom the disease was more severe. The sarcoma risk in EXT1 carriers is similar to the risk of breast cancer in an older population subjected to breast-screening, suggesting that a role for regular screening in patients with hereditary multiple exostoses is justifiable

Autologous chondrocyte implantation (ACI) and mosaicplasty are both claimed to be successful for the repair of defects of the articular cartilage of the knee but there has been no comparative study of the two methods. A total of 100 patients with a mean age of 31.3 years (16 to 49) and with a symptomatic lesion of the articular cartilage in the knee which was suitable for cartilage repair was randomised to undergo either ACI or mosaicplasty; 58 patients had ACI and 42 mosaicplasty. Most lesions were post-traumatic and the mean size of the defect was 4.66 cm. 2. The mean duration of symptoms was 7.2 years and the mean number of previous operations, excluding arthroscopy, was 1.5. The mean follow-up was 19 months (12 to 26). Functional assessment using the modified Cincinatti and Stanmore scores and objective clinical assessment showed that 88% had excellent or good results after ACI compared with 69% after mosaicplasty. Arthroscopy at one year demonstrated excellent or good repairs in 82% after ACI and in 34% after mosaicplasty. All five patellar mosaicplasties failed. Our prospective, randomised, clinical trial has shown significant superiority of ACI over mosaicplasty for the repair of articular defects in the knee. The results for ACI are comparable with those in other studies, but those for mosaicplasty suggest that its continued use is of dubious value

Aims

To identify a suite of the key physical, emotional, and social outcomes to be employed in clinical practice and research concerning Perthes' disease in children.

Nerve injury is a rare complication of total hip replacement which may be related to the exposure used for the operation. The posterior approach is traditionally associated with injury to the sciatic nerve. We have compared the incidence of nerve injury after primary total hip replacement (THR) using either a posterior or a direct lateral approach. We studied 42 consecutive patients undergoing primary total hip replacement. The surgeons used a posterior (22 patients) or direct lateral (20 patients) approach in accordance with their normal practice. The obturator, femoral, posterior tibial and common peroneal nerves were assessed clinically and electrophysiologically by electromyography (EMG) and measurement of the velocity of nerve conduction before operation and at four weeks after. All patients were free from symptoms of nerve injury after operation but five lesions were identified in four patients by the electrophysiological studies; the obturator nerve was involved in two, the femoral in one, the common peroneal in one and the posterior tibial in one. All these injuries occurred using the lateral approach. Clinical assessment alone underestimates the incidence of nerve injury complicating THR. Our study does not confirm the association of nerve injury with the posterior approach which had been described previously

During a six-year period (January 1996 to January 2002 ), we re-explored 60 interspaces (49 patients, 49 feet) for recurrence or persistent symptoms after one or more previous procedures for excision of an interdigital neuroma. Ten patients underwent concomitant excision of a primary neuroma from an adjacent interspace, and 19 underwent concomitant forefoot surgery. The mean follow-up was 39.7 months (6 to 79). Evaluation included review of records and radiographs, clinical assessment, and a questionnaire regarding satisfaction, pain, restriction of footwear and activity. In total, 15 patients (30.7%) were completely satisfied, 13 (26.5%) were satisfied with minor reservations, ten (20.4%) were satisfied with major reservations and 11 (22.4%) were dissatisfied with the outcome. Of the 49 patients, 28 (57.2%) had no or mild pain, 29 (59.2%) had moderate or severe restriction of footwear and eight (16.3%) had moderate restriction of activity. Intra-operative findings, simultaneous surgery to adjacent interspaces, concomitant forefoot surgery and previous re-explorations did not significantly influence the outcome. Persistent or recurrent symptoms after transection of a nerve present a challenging problem for both the surgeon and patient. It is essential that there is a thorough pre-operative discussion with the patient, providing the rates of failure and the increased likelihood of restriction of footwear and activity after revision surgery

We reviewed the results of 13 adults of secondary reconstruction of malunited and ununited intraarticular distal humeral fractures. Their average age was 39.7 years, and preoperatively all had pain, loss of motion and functional disability; the average arc of motion was only 43 degrees and the average flexion contracture was 45 degrees. Nine patients had ulnar neuropathy. Elbow reconstruction, at an average of 13.4 months after the original injury, included osteotomy for malunion or debridement for nonunion, realignment with stable fixation and autogenous bone grafts, anterior and posterior capsulectomy and ulnar neurolysis. The elbows were mobilised 24 hours postoperatively. There were no early complications and all nonunions and intra-articular osteotomies healed. After a mean follow-up of 25 months, the average arc of motion was 97 degrees with no progressive radiographic degeneration. Ulnar nerve function improved in all cases and clinical assessment using the Morrey score showed two excellent, eight good and three fair results. Reconstruction of intra-articular malunion and nonunion of the distal humerus in young active adults is technically challenging, but can improve function by restoring the intrinsic anatomy of the elbow

We investigated the outcome of deep-vein thrombosis (DVT) in the calf after total knee arthroplasty (TKA) in 48 patients (45 women and three men) by clinical assessment and venographic study between three and four years after surgery. The mean age of the patients was 67.2 ± 7.7 years (52 to 85) and the mean follow-up was 42.6 ± 2.7 months (38 to 48). The diagnosis was osteoarthritis in 47 patients and rheumatoid arthritis in one patient. There were 44 calf thrombi, four popliteal thrombi but no thrombi in the femoral or iliac regions. Of the 48 patients, 24 were clinically symptomatic and 24 were asymptomatic. Clinical examination was carried out on 41 patients, of whom 37 underwent ascending venography. Seven were evaluated by telephone interview. No patient had the symptoms or signs of recurrent DVT, venous insufficiency in the affected leg, or a history of pulmonary embolism. No patient had been treated for complications of their DVT. Thirty-six of the 37 venographic studies were negative for either old or new DVT in the affected leg. One patient had residual thrombi in the muscular branches of the veins. Our study shows that deep-vein thromboses in the calf after TKA disappear spontaneously with time. No patient developed a recurrent DVT, proximal propagation or embolisation. Treatment of DVT in the calf after TKA should be based on the severity of the symptoms during the immediate postoperative period

1. Forty-five patients with monarthritis of at least six months duration have been reviewed. Arthrotomy and synovial biopsy were carried out in every case. The period of follow-up varied from two to eight years from the time of biopsy. A re-examination of the biopsy material was made at the time of clinical assessment. 2. Twelve patients (27 per cent) were diagnosed as having definite or probable rheumatoid arthritis. Four patients (9 per cent) had psoriatic arthropathy and six (13 per cent) had a persistent monarthritis of undetermined type. A further four patients (9 per cent) had polyarthritis of undetermined type, ten (22 per cent) were diagnosed as having osteoarthritis and seven (16 per cent) were completely normal (self-limiting joint disease). 3. There was a moderately good relationship between biopsy findings suggestive of rheumatoid arthritis and the eventual clinical outcome. 4. Monarthritis of the wrist was followed in every case by the development of significant disease, either rheumatoid arthritis or psoriatic arthropathy. 5. Rheumatoid arthritis may remain monarticular for many years. 6. It is concluded that thorough investigation of patients with monarthritis is of considerable help in diagnosis and prognosis

Aims

The aim of this study was to examine whether tourniquet use can improve perioperative blood loss, early function recovery, and pain after primary total knee arthroplasty (TKA) in the setting of multiple-dose intravenous tranexamic acid.
