Hematoma and distraction arthroplasty for thumb basal joint osteoarthritis: minimum 6.5-year follow-up evaluation.

PURPOSE: Although hematoma and distraction arthroplasty has been found to be successful in the treatment of thumb basal joint arthritis in the short term, questions about its efficacy in the long term have been raised. The goal of the present study was to evaluate the results of this procedure in patients at least 6.5 years after surgery. METHODS: Twenty-two thumbs from 22 patients from a single surgeon's practice were entered into a prospective single-arm study for surgical treatment of basal thumb arthritis. Treatment consisted of piecemeal excision of the entire trapezium and 5 weeks of K-wire immobilization of the thumb metacarpal in opposition and slight distraction. No ligament reconstruction or tendon interposition was used. Motion, strength, standardized dexterity tests, stress radiographs, and outcome questionnaires including the Arthritis Impact Measurement Scales 2 were evaluated before surgery and at 6, 24, and at least 79 months after surgery. RESULTS: At 6 months after surgery, 17 of 22 patients reported complete pain relief, and at the most recent follow-up evaluation (average, 88 months after surgery) 18 patients were entirely pain free. Range-of-motion evaluation at the most recent follow-up evaluation showed 21 of 22 thumbs adducted fully into the plane of the palm, and 21 of 22 opposed to the small finger metacarpal head. Comparisons between preoperative and the recent postoperative strength measurements showed an average of 21% increase in grip strength and tip pinch strength, and an 11% increase in key pinch strength over preoperative values. Although the radiographically determined scaphoid-thumb metacarpal distance decreased with time from surgery, no correlation with strength or functional outcome measurements was found. The Arthritis Impact Measurement Scales 2 data showed postoperative improvement in the hand and finger function and arthritis pain scales. CONCLUSIONS: After trapezial excision, K-wire immobilization in a slightly overcorrected position without formal interposition or ligament reconstruction allows for restoration and maintenance of a stable, pain-free thumb that has comparable strength and motion with published reports of more complicated interventions over comparable time periods. TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic, Level IV.

Trapeziectomy.

Primary osteoarthritis of the carpometacarpal joint of the thumb is common, especially in women aged 60 or older. Patients usually present with activity-related pain at the thumb base. First treatment may include activity modification, pain relieving medications, splinting, and possibly corticosteroid injections. When these measures fail to pre-serve or restore the patient's quality of life, surgical intervention may be appropriate. Many surgical alternatives are described for the treatment of thumb carpometacarpal joint arthritis, and most begin with at least partial trapeziectomy. Hematoma-distraction arthroplasty results in improved outcomes as compared with historical results following trapeziectomy alone. Temporary distraction allows the body's healing response to fill in the trapezial void with scar tissue, obviating the need for ligament reconstruction or tissue interposition.

The history of fracture fixation of the hand and wrist.

UNLABELLED: The treatment of fractures of the hand and wrist has evolved over the centuries from one of rest and immobilization to internal fixation and early motion. Although today's technology (anesthesia, antibiotics, metal implants) has allowed us more freedom in treating these injuries, a number of our patients continue to experience stiffness, nonunion, malunion, and chronic pain. We explore the techniques used to treat hand and wrist fractures throughout the centuries and determine what beneficial aspects of fracture care have been maintained and those that have changed as a result of new technology. We are now realizing that rigid immobilization of fractures at the expense of the soft tissues can be just as damaging as the ancient physician's techniques of prolonged immobilization with frequent dressing changes. New implants and lighter cast materials have allowed improved digital motion and early functional use of the extremity. This has become especially important in the treatment of the aging population, which demands improved function and a quicker return to activities. The optimal treatment of these fractures for each patient remains elusive, however, and there remains a tendency to rely on technology at the expense of sound clinical care. We must not loose sight of the goals of fracture treatment and should heed the lessons learned throughout centuries of treating these injuries. LEVEL OF EVIDENCE: Level V (expert opinion).

Flexor tenolysis.

Flexor tenolysis is a challenging procedure with valuable clinical usefulness in the restitution and enhancement of digital function in the appropriate patient. In the absence of complications, improvement in digital flexion can be expected. The requisites for success are a skilled surgeon, a motivated and well informed patient, and a closely monitored hand therapy program.

The historical importance of the hand in advancing the study of human anatomy.

Anatomy is often considered the foundation of medical science and is basic to the education of health professionals. This report will attempt to summarize the history of anatomy from antiquity to modern times. In addition it will highlight the historical importance of the upper extremity and its relationship to the development of human anatomy as a recognized medical science.

Proximal interphalangeal joint stiffness: measurement and analysis.

PURPOSE: The purpose of this study was to quantify the stiffness of the human finger proximal interphalangeal (PIP) joint and to study its relationship to different common clinical parameters. METHODS: Eighty-nine normal adult subjects had their PIP joints of the index, middle, and ring fingers evaluated using a computer-controlled moment-angle plotter. This device was used to measure stiffness and energy absorbed at the PIP joint during passive flexion and extension. RESULTS: The average overall stiffness was 0.05 N-cm/degree. There was a weak correlation between stiffness and energy absorbed and the size of the finger: they both increased with the size of the finger. The men's fingers were stiffer and absorbed more energy than the corresponding women's fingers. No significant associations were found between the time of day when the test took place, occupation, hobbies, or age with stiffness or absorbed energy. No significant differences were associated with hand dominance. The finger on the dominant hand had a larger circumference for both genders. Heavier individuals had more stiffness and absorbed more energy than lighter individuals. CONCLUSIONS: The PIP joint stiffness was defined quantitatively and measured over a wide cross-section of a normal population. This may allow future studies to record the outcome of different treatments for finger joint stiffness objectively. The stiffness was greater in men and in larger fingers.

Hematoma and distraction arthroplasty for basal thumb osteoarthritis.

Many surgeons have abandoned the simple trapeziectomy for the treatment of thumb basal joint arthritis secondary to reports of postoperative weakness. More recently, ligament reconstruction techniques have been the favored surgical procedure for the treatment of trapezial arthritis, but the necessity of such an extensive procedure that requires tendon harvest and rerouting has come into question. Simple trapeziectomy modified with distraction pinning, without interposition grafting, allows for a stable, pain-free thumb that has superior strength and motion when compared with the more complicated ligament reconstruction techniques.

Misrepresentation of research publications among orthopedic surgery fellowship applicants: a comparison with documented misrepresentations in other fields.

STUDY DESIGN: A retrospective study was used to review fellowship applications over 3 years. OBJECTIVES: To assess the prevalence of research misrepresentation in orthopedic fellowship applications, and to compare such activity between subspecialties (e.g., spine, sports, hand). SUMMARY OF BACKGROUND DATA: Competition for orthopedic surgery fellowships is intense. The applicant pool includes orthopedic, plastic, and general surgeons, as well as neurosurgeons. Residency and fellowship training programs in other disciplines have documented shocking levels of misrepresentation in the curriculum vitae of prospective applicants. However, no study has looked at orthopedic residents applying for subspecialty fellowship programs. METHODS: A retrospective analysis investigated 280 applications for fellowship positions in the department of orthopedic surgery at the authors' academic institution from 1996 to 1998 inclusively. To allow for press and publication delays, a minimum 24-month follow-up period was instituted. The listings of applicants' research publications were analyzed for evidence of misrepresentation through an exhaustive literature search. Only the most obvious confirmable discrepancies were labeled as misrepresentations. The results then were compared with those found in studies conducted in other fields: gastroenterology fellowship, emergency medicine residency, pediatric residency, dermatology residency, orthopedic residency, and medical faculty applications. RESULTS: Among 280 (54%) applicants for orthopedic surgery fellowships, 151 claimed journal publications. It was found that 16 (10.6%) of these 151 applicants had misrepresented their citations. This rate was highest in spine fellowship applicants (20%). However, considering the numbers available, this was not significantly different among the various subspecialty fellowship applicants (P > 0.1). In addition, various demographic data did not correlate with the rate of misrepresentation (P > 0.1). These results are comparable with those reported in other medical fields (P > 0.1). CONCLUSIONS: Misrepresentation occurs in orthopedic fellowship applications at a rate comparable with that observed in other fields. This rate is not different among the various subspecialties in orthopedics. Policies that may lessen the incidence of falsification on curriculum vitae should be instituted in an attempt to curb such activity.

Hematoma and distraction arthroplasty for thumb basal joint osteoarthritis: a prospective, single-surgeon study including outcomes measures.

PURPOSE: Many surgeons have abandoned the simple trapeziectomy as a surgical treatment option for thumb basal joint arthritis secondary to reports of postoperative weakness. The thumb metacarpal subsiding into the trapezial void has been proposed as the causative factor. The goal of the present study was to evaluate the results of trapeziectomy and postoperative K-wire immobilization of the thumb metacarpal in a distracted position without the use of ligament reconstruction or tendon interposition. METHODS: Twenty-six thumbs in 26 patients from a single surgeon's practice were entered into a prospective single-arm study for surgical treatment of peritrapezial arthritis. Treatment consisted of piecemeal excision of the entire trapezium and 5 weeks of K-wire immobilization of the first metacarpal in slight distraction and opposition. No ligament reconstruction or tendon interposition was used. Motion, strength, stress radiographs, standardized dexterity tests, and outcomes questionnaires including the Arthritis Impact Measurement Scales 2 (AIMS2) were evaluated before surgery and 6 and 24 months after surgery. RESULTS: At 6 months 19 of 26 patients (73%) reported complete relief of pain and at 24 months 92% were entirely pain free. Range of motion evaluation showed 24 of 26 thumbs adducted fully into the plane of the palm and 25 of 26 opposed to the fifth metacarpal head. Comparisons between preoperative and 24-month postoperative strength measurements showed an average 47% increase in grip strength, 33% increase in key pinch strength, and a 23% increase in tip pinch strength over preoperative values. AIMS2 data showed postoperative improvement in "hand and finger function" and "arthritis pain" scales. CONCLUSIONS: After trapezial excision K-wire immobilization in a slightly overcorrected position without tissue interposition or ligament reconstruction restores a stable, pain-free thumb that has superior strength and motion compared with published reports of the more complicated interventions.
