Iatrogenic flexor tendon rupture caused by misdiagnosing sarcoidosis-related flexor tendon contracture as tenosynovitis: A case report.

Background: Sarcoidosis is a multisystem disease characterized by granuloma formation in various organs. Sarcoidosis-related flexor tendon contractures are uncommon in clinical settings. This contracture is similar to stenosing tenosynovitis and potentially leads to misdiagnosis and mistreatment.

Comparative study of radial head resection and prosthetic replacement in surgical release of stiff elbows.

Purpose: Elbow trauma can compromise the arc of elbow flexion and forearm rotation. This study aimed at comparing the outcomes of radial head resection and prosthetic replacement in the surgical release of post traumatic elbow stiffness and associated restriction in forearm rotation.

Methods: We retrospectively reviewed the data of patients who underwent open arthrolysis with radial head resection (n = 15; resection group) or radial head replacement (n = 19; replacement group).

Effect of cryotherapy after elbow arthrolysis: a prospective, single-blinded, randomized controlled study.

Objective: To investigate the effect of cryotherapy after elbow arthrolysis on elbow pain, blood loss, analgesic consumption, range of motion, and long-term elbow function.

Design: Prospective, single-blinded, randomized controlled study.

Setting: University hospital.

[Expression and significance of substance P, neurofilament-H in glomus tumors with chronic pain].

Objective: To observe the expression and distribution of substance P (SP), neurofilament-H (NFH) in glomus tumors with chronic pain, and to discuss the process of chronic pain and the relationship with pain degree.

Methods: Twenty-seven patients diagnosed as glomus tumor with chronic pain were enrolled as case group, and divided into light pain symptomatic group (LPSG) (n = 12) and severe pain symptomatic group (SPSG) (n = 15) according to clinical manifestations. Control group (CG) were enrolled by 30 patients with amputated extremities or hands after trauma.
