A detailed analysis of long-term outcomes following reconstruction for congenital thumb hypoplasia.

This retrospective study analyses long-term outcomes of reconstruction for congenital thumb hypoplasia Grades 2 and 3 A. In 22 thumbs (mean follow-up 9 years), instability of the metacarpophalangeal joint was found in 20 thumbs regardless of the method of reconstruction, double breasting of local tissue with or without adductor pollicis advancement or use of a slip of flexor digitorum superficialis to supplement local tissue. There was a trend towards a greater global strength, higher Kapandji score and better subjective function score when the abductor digiti minimi was used as an opposition transfer as compared with the flexor digitorum superficialis.

A Playtime and Handicap Analysis of 143 Regular Golfers After Total Knee Arthroplasty at Minimum 2-Year Follow-Up.

Background: Regular and competitive golfers are concerned by the ability to recover their previous activity golfing after total knee arthroplasty (TKA). The purpose of this study was to conduct targeted analysis of the effect of unilateral total knee replacement on the playtime and golf level in a population of experienced golfers, with a minimum follow-up of two years.

Methods: Questionnaires were distributed to the French Golf Federation's golfing members.

Views and Experiences of Travelers from US States to Zika-Affected Areas.

Travelers to areas with Zika virus transmission are at risk of infection and of transmitting the virus after returning home. While protective behaviors during and after travel can reduce these risks, information about traveler practices or underlying views is limited. We examined these issues using data from the first representative poll of travelers from US states to Zika-affected areas, including US territories and Miami, Florida, conducted December 1 to 23, 2016.

Upper limb surgery for severe spasticity after acquired brain injury improves ease of care.

For individuals with acquired brain injury and severe upper limb spasticity, personal care is often difficult, time-consuming and painful. Previous studies on outcomes after surgery for upper limb spasticity have focused on functional gain, pain, hygiene and appearance. We operated on 38 non-communicative patients (45 limbs, 535 procedures) with severe spasticity and a non-functional upper limb(s).

How did Ebola information spread on twitter: broadcasting or viral spreading?

Background: Information and emotions towards public health issues could spread widely through online social networks. Although aggregate metrics on the volume of information diffusion are available, we know little about how information spreads on online social networks. Health information could be transmitted from one to many (i.

The Effect of Extensor Tendon Adhesions on Finger Motion.

Purpose: To quantify the amount and pattern of finger range of motion loss at the metacarpophalangeal (MCP), proximal interphalangeal (PIP), and distal interphalangeal (DIP) joints with a simulated extensor tendon adhesion at the level of the proximal phalanx or metacarpal.

Methods: In 10 cadaveric specimens, traction sutures were placed in the forearm extensor digitorum communis and flexor digitorum profundus tendons of the middle and ring fingers. Active motion was simulated by suspending weights from the traction sutures via pulleys.

Cadaveric Dissection of the Axillary Nerve: An Investigation of Extra-Muscular and Intra-Muscular Branching Patterns.

Background: Variations in the axillary nerve branching patterns have been reported. The aim of the study is to investigate the extra- and intra-muscular course of the axillary nerve and quantify the regional innervation of the deltoid.

Methods: In fresh frozen specimens, the origin of the axillary nerve from the posterior cord of the brachial plexus and its extra- and intra-muscular course were identified.

Cost Comparison of Collagenase Clostridium Histolyticum and Fasciectomy for Treatment of Dupuytren's Contracture in the Australian Health System.

Background: Dupuytren's disease results in contracted cords in the hand that lead to deformity and disability. Current treatment options include fasciectomy and an injectable, collagenase clostridium histolyticum. No cost comparison studies have been published within the Australian health care environment.

A Conceptual Model for Evaluating Emergency Risk Communication in Public Health.

Public health threats, such as emerging infectious diseases, terrorism, environmental catastrophes, and natural disasters, all require effective communication. Emergency risk communication is a critical component of public health emergency planning and response. It is a complex process involving a variety of constructs that interact in dynamic ways over time.

Mechanics of Metacarpophalangeal Joint Extension.

Purpose: It is a common belief that extension of the metacarpophalangeal (MCP) joint of the finger is achieved via the sagittal bands acting as a sling or lasso to attach the extensor tendon to the base of the proximal phalanx. The aim of this study was to test the hypotheses that (1) division of the sagittal bands reduces extension force or torque of the MCP joint, and (2) division of the extensor tendon distal to the sagittal band will not affect the extension force or torque of the MCP joint.

Methods: Ten cadaver limbs were secured to a jig to allow for testing of the extension force of the MCP joints of the index, middle, and ring fingers.

Effects of Removal and Reinsertion of Headless Compression Screws.

Purpose: This study investigates the loss of compression when 3 commonly used headless compression screws are backed out (reversed), and assesses the ability to re-establish compression with screws of greater diameter.

Methods: Two investigators tested 3 screw designs (Acutrak 2, Synthes HCS, Medartis SpeedTip CCS) in 2 diameters and lengths. Each design had 10 test cycles in a polyurethane foam bone model with compression recorded using a washer load cell.

Neutrophilic Dermatosis of the Hands: A Review of 17 Cases.

Purpose: Neutrophilic dermatosis of the hands is an inflammatory skin condition related to Sweet syndrome that responds to corticosteroids. It commonly affects the dorsum of the hand and often mimics infection, with violaceous inflammatory papules and plaques that may ulcerate. The aim of this study was to review the clinical presentation of neutrophilic dermatosis of the hands.

RELIABILITY AND VALIDITY OF A BIOMECHANICALLY BASED ANALYSIS METHOD FOR THE TENNIS SERVE.

Background: An observational tennis serve analysis (OTSA) tool was developed using previously established body positions from three-dimensional kinematic motion analysis studies. These positions, defined as nodes, have been associated with efficient force production and minimal joint loading. However, the tool has yet to be examined scientifically.

ACUTE CHANGES IN PASSIVE GLENOHUMERAL ROTATION FOLLOWING TENNIS PLAY EXPOSURE IN ELITE FEMALE PLAYERS.

Background: Alterations in glenohumeral (GH) rotation especially internal rotation and total range of motion have been associated with altered GH kinematics and susceptibility to injury. Researchers have evaluated long-term change in baseball and tennis players, and short-term changes in baseball players. However, acute (short-term) changes in GH rotation have not been evaluated in tennis players.

An assessment of 2 objective measurements of web space position.

Purpose: To describe 2 simple objective clinical methods of measuring the web position between fingers and to determine their intra-observer and inter-observer reliabilities.

Methods: Two observers examined the second, third, and fourth web spaces on both hands of 30 adult healthy volunteers. The web index measured the web height as a relative ratio to constant anatomical landmarks on both fingers subtending the web.

A2 pulley integrity and the strength of flexor tendon repair: a biomechanical study in a chicken model.

Purpose: This study assesses the influence of A2 pulley integrity on the strength of the repair.

Method: Part 1- The flexor digitorum profundus (FDP) tendons of 72 Cobb chicken feet were severed and repaired in the region of the A2 pulley using a modified Kessler core suture and an epitendinous suture. The A2 pulley was either left intact, divided for 50% of its length, or divided in its entirety.

Mobile garbage bins and hand injuries in older people.

Objectives: To conduct a database search, chart and literature review of open extensor tendon and proximal interphalangeal joint injuries incurred while handling mobile garbage bins.
