Carpal Tunnel Syndrome and Work

The incidence, age at presentation, disability and outcome after surgery were investigated in 327 consecutive women of working age presenting to a hand unit with carpal tunnel syndrome. Two hundred and seventeen were working, 55 of these in repetitive occupations. One hundred and ten were not in employment. All three groups had similar mean ages (around 46 years). On a population basis more women in non-repetitive occupations presented with carpal tunnel syndrome (220/100,000/year) than those in repetitive work (122/100,000/year) or those not working (129/100,000/year), and more were offered surgery (82% versus 67% for those in repetitive work and 58% for those not working). However, symptoms and disability; as assessed with the Michigan Hand Questionnaire and the SF-12, were less severe in working women. This study suggests that working in repetitive or non-repetitive occupations does not cause, aggravate or accelerate carpal tunnel syndrome. Working women may struggle to accommodate their symptoms compared to women who are not in employment causing more to seek help.

Providing Care for Hand Disorders a Re-Appraisal of Need

An audit of hand surgery activity in Derby during the period 1989–1990 produced manpower and resource recommendations for the speciality per 100,000 of population per year for the United Kingdom. The decade that followed the audit has seen major changes in health care provision, including reduced service activity by trainee doctors through restricted hours of work and less unsupervised surgery. A further audit of hand surgery activity was performed during 2000–2001 to assess the effects of these and other changes. This showed that there has been a 2% rise in trauma attendances, though trauma bed utilization had reduced by 12% and surgery time by 38%. Trauma out-patient visits had also reduced by 11%. Day-case trauma surgery rates were virtually unchanged at 63%. Women attend more frequently with traumatic hand injuries than they did 10 years ago and there is arising incidence of hand injuries in the home, with a falling incidence at work. Elective referrals have risen by 36% and operations by 34%. The top ten diagnoses relate to the same conditions although their rankings have changed. Elective day-case surgery rates have risen from 64% to 94% over the decade. The 34% increase in elective operations has been absorbed within a 5% reduction in elective bed use and a 23% reduction in surgery time. Elective out-patient visits have also dropped 14% overall. This audit indicates that in 2000–2001 one whole time equivalent hand surgeon can service a population of 125,000. The national requirement for a 56 million population would be 448 whole time equivalent hand surgeons.

Carpal Tunnel Syndrome in Association with Hand–Arm Vibration Syndrome: A Review of Claimants Seeking Compensation in the Mining Industry

Twenty six thousand eight hundred and forty-two miners seeking compensation were clinically assessed for vascular and neurosensory impairment arising from exposure to occupational hand–arm vibration (Hand–Arm Vibration Syndrome). They were also assessed clinically for Carpal Tunnel Syndrome which, if present, would result in additional compensation.

Fifteen per cent were assessed as having both HAVS and CTS. Thirty-eight per cent of claimants had nocturnal wakening, 1.3% wasting of abductor pollicis brevis, 15% had a positive Tinel’s test and 20% had a positive Phalen’s test. The 15% prevalence reported is lower than the rates cited previously in several small population studies of workers exposed to vibration.

This paper reports the results of the assessment process and discusses the difficulty of discriminating Carpal Tunnel Syndrome from diffuse neurosensory impairment arising from HAVS.

A Prospective Assessment of Carpal Tunnel Surgery with Respect to Age

Six hundred and thirty five carpal tunnel decompressions in 490 patients were studied prospectively in two hand surgery centres to assess the effect of increasing age on the outcome after surgery. The outcome was assessed using the Levine–Katz carpal tunnel questionnaire, Tinel’s sign, Phalen’s test, Semmes–Weinstein monofilaments and pinch and grip strengths. Assessments were made pre-operatively, at 2 weeks and 6 months postoperatively. Information was also sought concerning co-morbid conditions. Cases were divided into four groups (less than 40 years of age, 40 to 60, 61 to 80, and over 80 years of age). Patients improved significantly in all age groups after carpal tunnel surgery. Despite a relatively high number of co-morbidities, older patients had an acceptable complication rate and their improvement was comparable to all other age groups.

Wound healing with medications for rheumatoid arthritis in hand surgery

Introduction. Medications used to treat rheumatoid arthritis, such as corticosteroids, disease-modifying agents (DMARDs), and injectable biological agents (anti-TNFα), may have widespread effects on wound healing. In hand surgery, it is important to balance the risks of poor wound healing from continuing a medication against the risks of a flare of rheumatoid arthritis if a drug is temporarily discontinued. Materials and Methods. A United Kingdom (UK) group of 28 patients had metacarpophalangeal joint replacement surgery in 35 hands (140 wounds). All medication for rheumatoid arthritis was continued perioperatively, except for the injectable biological agents. Results. There were no instances of wound dehiscence or deep infection and only one episode of minor superficial infection. Conclusions. We conclude that provided care is taken to identify and treat any problems promptly, it is appropriate to continue most antirheumatoid medications in the perioperative period during hand surgery to reduce the risk of destabilising the patients' overall rheumatoid disease control.

WRIST DENERVATION IN ISOLATION: A PROSPECTIVE OUTCOME STUDY WITH PATIENT SELECTION BY WRIST BLOCKADE

Surgical wrist denervation involves division of the anterior and posterior interosseous nerves and articular branches of the superficial radial nerve. In this outcome study, 37 patients were individually assessed and deemed suitable for denervation surgery due to appreciable symptom resolution following a local anesthetic wrist block. At a mean of 18 months following denervation surgery, median activity pain scores had decreased by 60% (p < 0.001) from initial assessment levels, and more than three quarters (30/37) of patients reported continued improvement in their activity pain (p < 0.001). More than two thirds of patients had a satisfaction VAS of greater than 50, with less postoperative resting pain and a greater reduction in postoperative activity pain as the important predictors of patient satisfaction. Thirty-one out of the 37 patients had not represented to our department for revision wrist surgery by a mean of 10.3 years follow-up. We have found this procedure useful in ameliorating symptoms for some patients who would conventionally have required partial or total wrist fusions with greater residual functional limitation.

Rheumatoid hand surgery: differing perceptions amongst surgeons, rheumatologists and therapists in the UK

Rheumatoid arthritis is a systemic disease that requires coordinated management by rheumatologists, surgical specialists and therapists working in a multidisciplinary team. Differences of opinion within the team may adversely affect patient care. Our aim was to assess differences in perception about rheumatoid hand surgery between rheumatologists, hand surgeons and hand therapists in the UK. We used a postal questionnaire to assess commonly performed rheumatoid hand operations. For each procedure, respondents rated the most important indication for surgery and scored effectiveness at reducing pain, improving function and aesthetics, and preventing deformity. Statistically significant differences were found between all three groups with regards to expected outcome and main indications for surgery. We concluded that significant differences do exist in the perceptions of rheumatologists, surgeons and therapists. Rheumatoid hand operations require more detailed study, clarifying indications and outcome to allow consistent advice to patients from all members of the multidisciplinary team.

A 6-year outcome of patients who cancelled carpal tunnel surgery

The long-term outcomes of patients with carpal tunnel syndrome who were scheduled for release but did not proceed to surgery were compared to patients who underwent surgery, matched on preoperative symptom scores. Both groups completed the Levine-Katz questionnaire 6 years after enrolment to our multicentre carpal tunnel syndrome outcomes database. Symptom and function scores improved for the surgical (n = 24) and non-surgical (n = 36) groups (p < 0.001). Improvement in symptom scores was greater in surgical patients compared to non-surgical patients (n = 24 matched pairs; p = 0.007) but improvement in function scores between groups was not significantly different (p = 0.13). For surgical patients, function and symptom scores improved by 6 months and were unchanged at 6 years. Patients planning surgical release can expect symptomatic and functional benefits within 6 months. Overall improvement was experienced by both groups, with a superior outcome achieved with surgery. The symptoms of carpal tunnel syndrome may improve without surgery, but further studies are needed to understand the natural history of the disorder.

Geoffrey Fisk and a hitherto unknown contribution to the treatment of carpal instability

We describe two films made by Geoffrey Fisk in 1973 that record midcarpal instability and its surgical treatment.

The use of the mini C-arm in the outpatient setting: evolving practice

The mini C-arm image intensifier (mini C-arm) has now become an established diagnostic tool in the hand surgery outpatient department. This study reviews the use of the mini C-arm and formal radiographs (X-rays) in the outpatient hand surgery setting. X-rays provide a standard image whereas the mini C-arm can obtain non-standard images to aid diagnosis and treatment. The mini C-arm enables the clinician to obtain dynamic images and perform interventions such as manipulations or injections. The mini C-arm results in a significantly lower radiation exposure for the patients than a formal X-ray. Use of the mini C-arm may be cheaper, and can lead to a shorter outpatient visit with less travel between hospital departments.

The benefit of radiologically-guided steroid injections for trapeziometacarpal osteoarthritis

INTRODUCTION

Osteoarthritis of the trapeziometacarpal joint (TMJ) is a common condition causing significant disability. Conservative treatments include intra-articular steroid injections.

PATIENTS AND METHODS

This clinical, observational study prospectively reviewed the longevity of benefit of steroid injections into the TMJ. Eighty-three patients were recruited with a median age of 62 years and injected with steroid and local anaesthetic under radioscopic guidance. They were followed up until the analgesic effects ceased with a questionnaire including visual analogue scores.

RESULTS

Two-thirds of patients were improved at 2 months, with nearly half having a 3-month improvement. One in six patients had a 6-month benefit, with some patients still improved 2 years after injection. Previously injected patients had a reduced duration of benefit compared to their previous injection. Severity of osteoarthritis did not affect the injection efficacy.

CONCLUSIONS

Based on this study, we recommend steroid injections in all degrees of TMJ osteoarthritis.

The clinical significance of malunion of fractures of the neck and shaft of the little finger metacarpal

The outcomes of 218 little finger metacarpal shaft and neck fractures that had been treated non-operatively, with no attempt at fracture reduction, were compared with those of 44 that had been treated operatively with fracture reduction and fixation (plates or K-wires). Outcome measures included the grip strength of the little finger and the DASH score. Fracture malunion was assessed by clinical measurement of little finger ray shortening and measurement of palmar angulation on the initial radiographs. The severity of palmar angular deformity did not affect the outcome of the 105 metacarpal neck or 113 metacarpal shaft fractures that had been treated non-operatively. There were no differences between the outcomes of the 18 metacarpal neck fractures treated operatively and the 105 treated non-operatively. The DASH score (P = 0.001) and aesthetic outcome (P = 0.013) were significantly better for the 113 metacarpal shaft fractures treated non-operatively than for the 26 treated operatively.

Long-term outcome after carpal tunnel decompression - a prospective randomised study of the Indiana Tome and a standard limited palmar incision

This randomised trial compared the results of carpal tunnel decompression using the TM Indiana Tome (Biomet, Warsaw, Indiana, USA) and a standard limited palmar open incision. Two hundred patients were randomly selected to have a carpal tunnel decompression with either the Indiana Tome or a limited palmar technique. They were assessed clinically for 3 months and using the Levine-Katz self-assessment evaluation for 7 years. After 7 years, there were 62 returned questionnaires from the open group and 53 from the Tome group. There were no significant differences in functional scores, pain, scar tenderness, pinch and grip strength at 3 months. There were two complications in the open group and nine in the Tome group, including one median nerve injury. There was both a higher rate of immediate complications, and more recurrences and persisting symptoms at 7 years in the Indiana Tome group.

Study to assess differences in outcome following open carpal tunnel decompressions performed by surgeons of differing grade

INTRODUCTION

Carpal tunnel decompression is the most commonly performed surgical procedure within a hand unit. Although very effective, the complications following the procedure can be significant. In an attempt to identify the causes of such complications, we assessed whether seniority of the surgeon impacts on outcome for open carpal tunnel decompression.

PATIENTS AND METHODS

Data were jointly and prospectively gathered from two units from either side of the Atlantic - the Pulvertaft Hand Center, UK and the Curtis Hand Center, USA. The aim of the study was to assess outcome following carpal tunnel decompression. Completed data were gathered following open carpal tunnel decompression on 352 hands. Surgeons of a consultant grade had performed 123 of these procedures whilst surgical trainees had performed 229 of the procedures. Assessment was by Levine Katz questionnaire results, Semmes-Weinstein testing, grip strength and pinch grip strength testing performed both pre-operatively and 6 months' postoperatively. Complications following the procedure were also recorded.

RESULTS

Mean results were found to be better in those patients where the surgeon was of a consultant grade. However, this was only found to be of statistical significance on Semmes-Weinstein testing. Complications following the procedure were also noted to be higher in the group of patients operated on by trainee grades.

CONCLUSIONS

Our results show the carpal tunnel decompression performed by a surgeon of consultant grade offers slightly better results in objective neurological testing when compared with those performed by a more junior grade.

Fractures of the tubular bones of the hand

Age related differences in demographics, morphology, treatment and outcome were investigated in 701 fractures of the metacarpals or phalanges, including fracture-dislocations, in 655 patients. Fractures mainly due to sport occurred in 184 children, usually after 10 years of age. The base of the proximal phalanx was especially vulnerable. Thirty-seven percent of 256 young adults fractured their fifth metacarpal. The thumb was rarely involved. Half of these two groups fractured the fifth ray. Older adults had more fractures of the distal phalanx and displaced extraarticular fractures requiring stabilisation. Women predominated in the patients over 65. Forty percent of this group sustained their fracture on the road and more fractures involved the thumb, were oblique, intraarticular or multiple than in other groups. Detailed analysis of 423 X-rays demonstrated that only 10% of 70 intraarticular fractures and 19% of 363 extraarticular fractures were completely undisplaced. Patient response to postal questionnaire based outcome assessment using SF-12, MHQ was very poor.

An audit of the safe use of the mini c-arm image intensifier in the out-patient setting

Mini C-arm image intensifiers are used commonly in surgery of the upper limb. With relatively low doses of emitted ionising radiation, portability and superior quality of image, they are a useful aid to the operating surgeon. However, these benefits are not so often used outside the theatre setting. This paper examines the use of a mini C-arm image intensifier in the out-patient clinic and presents an audit of 100 consecutive out-patients. We reviewed the potential benefits and effects on their care pathway. We also look at the specific radiation protection issues of the mini C-arm image intensifier in the out-patients clinic. We believe use of the mini C-arm image intensifier in the out-patient setting may speed treatment and reduce the cost of treatment.

An assessment of the effects of exposure to vibration, smoking, alcohol and diabetes on the prevalence of Dupuytren's disease in 97,537 miners

A consecutive sample of 97,537 miners seeking compensation for Hand-Arm Vibration Syndrome were examined in a medical assessment process which included documentation of age, hand dominance, Dupuytren's disease, years of vibration exposure, history of diabetes, smoking habits and units of alcohol consumption per week. The prime determinant of prevalence of Dupuytren's disease was age, and all other factors investigated were corrected for age. There was no statistically significant correlation between years of exposure to vibration and the prevalence of Dupuytren's disease. There was a statistically significant association with smoking, alcohol consumption and diabetes mellitus, with the heaviest smokers having an odds ratio (OR) of 1.31 (95% CI, 1.17, 1.47), the heaviest drinkers (in excess of 22 units a week) having an OR of 1.59 (95% CI, 1.47, 1.72) and diabetes mellitus patients having an increase in the odds of having Dupuytren's disease of 1.52 (95% CI 1.30, 1.77).

Social deprivation and hand injury

This study investigated the relationship between socioeconomic deprivation and the incidence, patterns of injury, process of care and outcome of hand trauma using data collected prospectively on 1234 injuries presented during six months. The Index of Multiple Deprivation 2004 was derived from census data and postcodes. Socioeconomic deprivation is significantly associated with hand trauma. The odds ratio for suffering hand injuries in the most deprived quintile is 1.6 (SE 0.09 95% CI 1.45, 1.83) compared to the least deprived quintile. This is most marked among older children and adults. Fractures, sprains and ligament injuries showed the strongest association with the degree of deprivation. Injuries related to sport were not associated with deprivation. Surgical time utilised is greater in more deprived patients and their self reported physical outcome is worse. Hand surgery units working in areas of high socioeconomic deprivation will have higher trauma workloads and unit costs. Social deprivation may also influence physical outcomes.

A technique to facilitate symmetrical and atraumatic placement of the core suture during flexor tendon repair

We present a technique aiding symmetrical accurate and atraumatic placement of the core suture during tendon repair. This technique facilitates a neat repair and avoids unnecessary contact with the tendon during the insertion of the core suture.

Study to outline the efficacy and illustrate techniques for steroid injection for trigger finger and thumb

AIM

To outline the efficacy of a steroid injection in treating trigger finger. Our study defines the anatomy of the A1 pulley, and suggests methods for simple and safe flexor sheath injection for trigger finger and thumb.

METHOD

Systematic review of published literature on trigger finger and thumb and its treatment, particularly steroid injection. The use of the knowledge of the superficial landmarks of the A1 pulley with the techniques described were combined to provide a comprehensive guide to injecting steroids in patients with trigger finger and thumb.

RESULTS

Several studies are outlined, which provided evidence to suggest that a steroid injection into the flexor sheath of the affected digit is successful in treating most of the patients. Methods of identifying the superficial landmarks of the A1 pulley and of approaching the pulley without injury to surrounding structures are also outlined in the literature. Two different techniques used to infiltrate the flexor sheath were described.

CONCLUSION

Steroid injection in the flexor sheath at the level of the A1 pulley is an effective method of treating patients with trigger finger and should be considered as the preferred treatment. Specific anatomical landmarks and methods allow the procedure to be carried out without fear of inadvertent damage to surrounding structures.

Lesiones por inyección de alta presión

En este artículo presentamos una visión histórica, fisiopatologica y terapéutica de las lesiones por inyección de alta presión a nivel de la mano.

Son lesiones que muy a menudo son tratadas de forma poco agresiva y radical debido en parte a un desconocimiento de la severidad que conllevan. Pretendemos con este articulo describir tanto el diagnostico, tratamiento y pronostico a partir tanto de la bibliografía existente como de nuestra propia experiencia en este campo. El diagnóstico precoz y el desbridamiento urgente son claves para reducir la tasa de amputación.

Primary care management of carpal tunnel syndrome

Carpal tunnel syndrome of mild to moderate severity can often be effectively treated in a primary care environment. Workplace task modification and wrist splints can reduce or defer referral to hospital for surgical decompression. Nerve and tendon gliding exercises may also be of benefit. Steroid injections to the mouth of the carpal tunnel are particularly useful for symptomatic women in the third trimester of pregnancy. However inadvertent neural injection may cause disabling chronic pain. Referral to a minority of practitioners trained in the technique would ensure sufficient patient numbers to maintain skill levels.

Assessing outcome after hand surgery: the current state

An overview of the current state of outcome measurement after hand surgery is presented. The paper focuses on the development, application and strengths and weaknesses of it also reviews the existing questionnaires and suggests recommendations for use in research or clinical practice.

The functional results of ray amputation

Twenty patients (14 males, six females) were assessed at an average of 32 months (ten to 156 months) after ray amputation using the disability shoulder, arm, hand (DASH) questionnaire, physical examination and functional testing. There were 14 border (eight index, six little) and six central ray (five middle, one ring) amputations. Our results showed on average 27% less grip and 22% three-point pinch strength in the operated hands. Peak power output was 22% and average work output 14% less on the operated side than the contralateral hand. The DASH function score was 29.2 (range 3.3-74.2). Nine patients returned to their previous occupation, two had to change jobs and two did not return to work. Six patients were not working, one was of school age. The ensuing disability remained within limits reflected by our measurements and the acceptance of the patients.

Primary care referral protocol for wrist ganglia

The paper summarises current knowledge on ganglia of the wrist including the views of patients and doctors. The efficacy of available treatment options are discussed. Summary points are derived from the available knowledge with a referral protocol from primary care.

Wrist function after excision of the pisiform

The pisiform bone may provide mechanical stability to the ulnar column of the wrist by preventing triquetral subluxation. Thus, surgical excision of the pisiform might cause loss of function to the wrist. We performed a functional evaluation of 20 hands in 20 patients who had undergone pisiformectomy for pisotriquetral joint dysfunction. At a mean follow-up of 65 months, 15 patients had complete relief of symptoms and five continued with mild discomfort. Compared with the unaffected wrist, there were no significant differences in grip strength and wrist movement, static strength and dynamic power. We conclude that pisiformectomy for pisotriquetral joint dysfunction can be safely recommended because restoration of function with a painless wrist is the normal outcome.

Primary care referral protocol for carpal tunnel syndrome

Carpal tunnel syndrome is an extremely common upper limb nerve compression syndrome, widely distributed in the community. There are a variety of treatment options which may be applied to the syndrome, depending on the severity of symptoms. Some options are available in a primary care setting, others require secondary referral. This paper is a detailed review of the available literature and provides a protocol that could be used to assist in the referral of patients from primary care.

Finger sucking digital deformities

We report our experience with severe digital deformities caused by prolonged finger sucking. Our analysis of nine patients demonstrated that the deformity was mainly located in the proximal and middle phalanges of the affected digit(s). We have reviewed the literature, enumerated the common patterns of "finger sucking" and explained the resulting deformities. Corrective osteotomy, preferably at the metacarpal base level, is required in severe deformities.

Functional outcome of high-pressure injection injuries of the hand

BACKGROUND

High-pressure injection (HPI) injury of the hand is a serious injury that can be potentially devastating. There have been a number of publications on the results of its treatment, but we are not aware of a report on the functional outcome of these hands.

METHODS

We assessed the functional outcome of 15 patients with HPI injuries. All patients were treated operatively, with a mean delay of 11.7 hours. The patients were examined by a doctor and an occupational therapist using a work simulator.

RESULTS

Our study revealed a significant reduction of static and dynamic muscle testing parameters compared with the uninjured hand. Six patients lost a digit and four patients had to change their occupation after the injury.

CONCLUSION

Deterioration of hand function is a predictable outcome of HPI injury. This information should be shared with the patient at the outset so as to avoid subsequent disappointment.

Carpal tunnel syndrome: reconciling "demand management" with clinical need

Purchasers of surgical services are seeking justification for operative interventions with increasing frequency. This paper seeks to identify all relevant data currently available for carpal tunnel decompression; one of the commonest operative interventions in hand surgery. Such data, as is available, would suggest carpal tunnel decompression rates in the United Kingdom are relatively low, with fairly prolonged preoperative duration of symptoms.

Open and closed arthrodesis of the rheumatoid wrist using a modified (Stanley) Steinmann pin

In a series of 21 patients (22 wrists) with rheumatoid arthritis, arthrodesis of the wrist was done using a modified Steinmann pin (Stanley) either by an open or closed technique. The open technique, which included fragmenting the carpal bones (12 cases), was mainly used when additional procedures were needed simultaneously. The closed technique simply required insertion of the Stanley pin under fluoroscan control through a small incision over the metacarpal head. Nine out of 12 wrists treated with the open technique and nine out of ten of those treated by the closed technique were successfully fused. Complications were few. A single patient was dissatisfied due to continuing pain. Two out of the four pins that migrated (both involving the open technique) have been removed.

The Ununited Scaphoid:Prognostic Factors in Delayed and Nonunions of the Scaphoid

This study attempts to classify scaphoid nonunions, identify the prognostic indicators of scaphoid nonunions and report the clinical, functional and radiographic results of scaphoid nonunions treated by Herbert screw and bone grafting. The patient population included 51 scaphoid nonunions in 50 patients treated by Herbert screw with or without bone graft. Group I was patients with delayed union; Group II was stable nonunions, Group IIIA consisted of unstable nonunions without DISI; Group IIIB included unstable nonunions with DISI deformity. Although the overall union rate was 84%, 87% stable nonunions (Groups I and II) united compared to only 60% unstable (Groups IIIA and B). This was statistically significant using the Chi-square test at p < 0.05. Thus, delayed unions and stable nonunions unite readily but unstable and displaced nonunions have significantly lower rates of union even after Herbert screw and bone grafting.

Recurrent anterior interosseous nerve palsies related to pregnancy

A rare association of anterior interosseous nerve palsy with pregnancy has been reported previously (Sood and Burke, 1997). We report further on this patient who has now experienced three separate anterior interosseous nerve palsies associated with pregnancies.

Trapeziectomy alone, with tendon interposition or with ligament reconstruction?

This randomized prospective study compared the results of trapeziectomy alone, or combined with tendon interposition or ligament reconstruction in 76 women with basal thumb osteoarthritis. At 3 month and 1 year follow-up the results of the three procedures were indistinguishable in terms of pain relief, hand function and thumb strength. In the short term at least, tendon interposition and ligament reconstruction do not improve the results of trapeziectomy.

Anterior interosseous nerve palsy. A review of 16 cases

Sixteen patients with paralysis of the anterior interosseous nerve (AIN) in 19 limbs who were treated in a single unit were reviewed at a mean of 6.4 years (range 2-14 years) following onset of the paralysis. There was a high incidence of incomplete lesions (seven limbs) and of associated neurological lesions (six limbs) in the same or opposite upper extremity. Patients treated conservatively and with surgical exploration showed no difference in the time of onset of recovery, the time taken to achieve complete recovery or the extent of recovery. Those with incomplete lesions recovered well irrespective of the type of treatment. A distinct cause of compression of the AIN or visible changes in the AIN were seen in just three of the eight limbs that were explored. Surgery is indicated in complete lesions with no evidence of recovery for at least 6 months; incomplete lesions and other neurological signs are indications for conservative management in the first instance.

Melorheostosis of the hand

We report a case of melorheostosis of the hand which showed a sclerotomal pattern of involvement, with swelling and pain. Surgical debulking resulted in correction of the deformity and relief of pain.

Rhabdomyosarcoma of the hand. Two case reports and a review of the literature

Two cases of rhabdomyosarcoma (RMS) of the hand are reported.

Psychosocial consequences of upper limb injury

Upper limb surgeons have little in the way of training in the identification or management of the psychological aspects of limb injury. Surgeons in training tend to see their specialty in technical terms, only slowly appreciating that the psychological state of the patient profoundly affects outcome in many cases. The case report that follows charts the psychological progress of a patient following severe upper limb injury. Surgeons usually view rehabilitation in physical terms. This report emphasizes the psychological aspects of a major limb injury to a policeman (MP) who subsequently studied psychology at PhD level.

Outcomes of hand surgery. British Society for Surgery of the Hand

The findings are presented of a conference on Outcomes of Hand Surgery organized by the audit committee of British Society for Surgery of the Hand in 1993. Measures of outcome in terms of movement, power, sensibility, pain, activities of daily living, complications and patient satisfaction are considered, and an example of a patient evaluation measure given as an appendix.

Veterinary high pressure injection injuries with inoculations for larger animals

Equipment used in the mass vaccination of farm stock is a source of high pressure injection injury. We present four cases due to chicken vaccine, and one due to pig vaccine. Unlike injuries caused by paint or oil guns the vaccination delivers a fixed volume. Although the vaccine is in a mineral oil carrier it appears to elicit little inflammatory reaction in a small dose. The outcome is related to the volume injected. In chicken vaccine the dose is small enough to allow conservative or minimally invasive management. The large volume in pig vaccine requires treatment as for conventional high pressure injection injuries.

Aneurysmal bone cysts in the hand treated by free non-vascular transfer of metatarsal or proximal phalanx from the foot

Two cases of aneurysmal bone cyst in the hand are reported. In one case the entire first metacarpal was resected and grafted using the fourth metatarsal. In the second case diaphysectomy of the middle phalanx of the index digit was performed, and the proximal phalanx of the second toe was used as graft. Satisfactory length and function were maintained, the grafts remained viable and there was no donor site morbidity. Transplant of a metatarsal or toe phalanx to the hand, as a free non-vascularized graft, is a relatively straight forward operation, requires minimal refashioning of the graft, provides articular surfaces for joint reconstruction and leaves little donor site morbidity.
