Effect of ice on pain after corticosteroid injection in the hand and wrist: a randomized controlled trial.

This prospective, randomized controlled study was designed to determine if applying ice to the site of corticosteroid injections in the hand and wrist reduces post-injection pain. Patients receiving corticosteroid injections in the hand or wrist at a tertiary institution were enrolled. Subjects were randomized to apply ice to the injection site and take scheduled over-the-counter analgesics ( n = 36) or take scheduled over-the-counter analgesics alone ( n = 32). There were no significant differences in the mean pain score between the two groups at any time-point (pre-injection or 1-5 days post-injection). In regression modelling, the application of ice did not predict pain after injection. Visual analogue pain scores increased at least 2 points (0-10 scale) after injection in 17 out of 36 patients in the ice group versus ten out of 32 control patients. We conclude that the application of ice in addition to over-the-counter analgesics does not reduce post-injection pain after corticosteroid injection in the hand or wrist.

Synpolydactyly of the hand: a radiographic classification.

UNLABELLED: Synpolydactyly is an uncommon congenital anomaly characterized by polydactyly with syndactyly in the central hand. The purpose of this investigation was to develop and assess the reliability of a radiographic classification system for synpolydactyly. We identified 56 hands with central synpolydactyly and developed a radiographic classification system that categorizes by the location within the hand, the bony level of polydactyly, and the presence of a delta phalanx. Four paediatric hand surgeons independently reviewed each radiograph to establish reliability. There was exact agreement among raters in 40 cases (71%). The inter-rater reliability was 0.97 and intra-rater reliability was at least 0.87. Seven of 16 bilateral cases had symmetric deformity classification. The most common presentations were types 1A and 2A. We present a new, reliable radiographic classification system for synpolydactyly that will allow improved communication between clinicians and serve as a foundation for future investigations. LEVEL OF EVIDENCE: 2.

Fracture-dislocation about the finger joints.

Fracture-dislocations in the small joints of the fingers are challenging injuries. The surgeon must choose an appropriate treatment based on fracture pattern, joint stability, and injury chronicity. Fracture-dislocations of the proximal interphalangeal joint are notoriously unforgiving, with potential long-term sequelae of residual pain and stiffness. Similar injuries in the distal interphalangeal joint are more tolerant of fracture displacement and even joint subluxation. Dorsal dislocations of the metacarpophalangeal joint may be associated with shearing fractures of the metacarpal head but are most notable for the volar plate interposition that may block closed reduction.

Hemi-hamate arthroplasty provides functional reconstruction of acute and chronic proximal interphalangeal fracture-dislocations.

PURPOSE: Hemi-hamate resurfacing arthroplasty is a treatment alternative for the management of severe acute and chronic dorsal proximal interphalangeal (PIP) fracture-dislocations. This study was designed to determine whether this procedure would successfully restore function after such injuries. METHODS: Hemi-hamate reconstructions were performed on 33 patients (mean age, 34 years) who presented to 1 hand surgery practice with dorsal PIP fracture-dislocations. Eligible patients experienced unstable dislocations with comminuted metaphyseal fractures involving at least 50% of the volar middle phalangeal surface that was not amenable to open reduction and internal fixation. We evaluated 22 patients with 14 acute (<6 weeks) and 8 chronic (mean, 30 weeks) injuries at a mean of 4.5 years (range, 1-7 years). Functional outcomes were assessed by objective and subjective measures: joint alignment/motion/stability, grip strength, Disabilities of the Arm, Shoulder, and Hand (DASH) scores, and visual analog scales (VAS) of pain and function. RESULTS: After hemi-hamate reconstruction, active PIP motion averaged 70 degrees (acute 71 degrees , chronic 69 degrees ) with a mean flexion contracture of 19 degrees (range, 0 degrees to 80 degrees ). Active distal interphalangeal motion averaged 54 degrees (acute 56 degrees , chronic 51 degrees ). The mean VAS score for digit pain was 1.4 (acute 0.7, chronic 2.5). The mean DASH score of 5 (acute 2, chronic 9) and VAS functional score of 1.9 (acute 1.4, chronic 2.6) indicated little functional impairment (acute 2, chronic 9). Grip strength averaged 95% of the opposite hand. Mean coronal plane angulation at the PIP joint was 3 degrees . Ten patients reported aching with cold temperatures. One dissatisfied patient underwent revision surgery. Chronic reconstructions were associated with increased VAS pain ratings (p = .02) and higher DASH scores (p = .06). CONCLUSIONS: Hemi-hamate reconstruction represents a valuable surgical procedure to address severe PIP joint fracture-dislocations. Reconstruction of chronic injuries by this method restores PIP function, albeit with more modest outcome performance. TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic IV.

Methicillin-resistant Staphylococcus aureus in orthopaedic surgery.

Methicillin-resistant Staphylococcus aureus (MRSA) has become a ubiquitous bacterium in both the hospital and community setting. There are two major subclassifications of MRSA, community-acquired and healthcare-acquired, each with differing pathogenicity and management. MRSA is increasingly responsible for infections in otherwise healthy, active adults. Local outbreaks affect both professional and amateur athletes and there is increasing public awareness of the issue. Health-acquired MRSA has major cost and outcome implications for patients and hospitals. The increasing prevalence and severity of MRSA means that the orthopaedic community should have a basic knowledge of the bacterium, its presentation and options for treatment. This paper examines the evolution of MRSA, analyses the spectrum of diseases produced by this bacterium and presents current prevention and treatment strategies for orthopaedic infections from MRSA.

Neurolysis of the distal superficial radial nerve for dysaesthesia due to nerve tethering.

The subcutaneous course of the superficial radial nerve over the radial border of the wrist and hand renders it very susceptible to injury. Both traumatic and iatrogenic injury can produce tethering of this nerve, presenting as dysaesthesia. This study was designed to evaluate the efficacy of neurolysis of the distal superficial radial nerve for this condition. Twenty-five cases of tethered superficial radial nerves underwent neurolysis. At final follow-up (mean 3.5 years), fourteen cases reported symptomatic resolution while eleven continued to experience dysaesthesia. Intra-operatively, evidence of external abnormality, scarring, or compression was identified in only six cases, and its presence did not correlate with symptomatic outcome. Although the majority of patients were improved postoperatively, the success rate was lower than anticipated. Therefore, while neurolysis of the superficial radial nerve offers the opportunity for pain relief, it does not reliably produce success.
