Trapeziectomy and Suture Suspensionplasty for Thumb Carpometacarpal Arthritis - Is In-Clinic Therapy Needed?

The Kapandji score is a widely used clinical metric for evaluating thumb opposition. It assesses the movement and functional reach of the thumb across into the palm and to the bases of the other fingers. The score ranges from 0 to 10, with each point representing the thumb's ability to touch distinct anatomical landmarks on the hand: from the radial side of the index finger base (score of 1) to the ulnar side of the little finger base (score of 10). This score helps in determining the functional impairment and potential recovery in cases involving thumb or hand injuries, often used in pre- and post-operative assessments.

Radial abduction refers to the movement of the thumb away from the hand's plane towards the radius, or the lateral side of the forearm. This motion is crucial for grasping larger objects and is an important aspect of hand function. It is commonly measured during hand and thumb functional assessments to evaluate the range of motion and strength, particularly after injury or surgery. Radial abduction is facilitated by several muscles, including the abductor pollicis longus, which plays a pivotal role in thumb movement and positioning.

Key pinch, also known as lateral pinch, involves the force applied between the thumb pad and the lateral side of the index finger. This specific type of pinch is crucial for activities that require precision, such as holding a key or grasping small objects. The key pinch is commonly assessed in occupational therapy and rehabilitation settings to evaluate hand function and grip strength, particularly after injury or in conditions affecting the nerves or muscles of the hand. Measurements are typically taken using a pinch gauge, which provides a quantitative value of pinch strength, helping in the assessment and monitoring of recovery progress.

Grip strength is the force applied by the hand to pull or suspend objects and is a key indicator of hand function and overall health. It's measured using a dynamometer, an instrument that the individual squeezes with maximum effort.

The PROMIS (Patient-Reported Outcomes Measurement Information System) Upper Extremity measure is a tool designed to assess self-reported upper extremity function. This measure evaluates the physical functioning and capability of the arms, shoulders, and hands based on the patient's perspective. Scores from this assessment are converted to a T-score metric, where 50 represents the mean of a relevant reference population, and each 10-point deviation represents one standard deviation from that mean. This standardization allows for the comparison of patient scores against population norms, which can be particularly useful in clinical trials, patient care, and research studies involving musculoskeletal health and rehabilitation.

The PROMIS-29 profile is a comprehensive tool that measures health across multiple domains using patient-reported outcomes. It evaluates seven key health domains along with pain intensity, offering a broad overview of a patient's health status. The domains include physical function, which assesses the ability to carry out physical activities; anxiety, evaluating feelings like fear and unease; depression, measuring feelings such as sadness and lack of interest; fatigue, assessing how often a patient feels tired; sleep disturbance, measuring perceptions of sleep quality; social roles and activities, evaluating the extent to which health limits participation in various activities; and pain interference, which assesses how pain hampers engagement in daily activities. Additionally, pain intensity is captured on a scale from 0 (no pain) to 10 (worst imaginable pain). Each domain consists of four questions, totaling 29 items. This tool is designed to be generic, suitable for a wide range of
