Treatment of chronic injuries of the ulnar collateral ligament of the thumb using a free tendon graft and bone suture anchors

We report the results of a simple technique, using bone suture anchors and free tendon graft, for the reconstruction of chronic injuries of the ulnar collateral ligament complex at the thumb metacarpophalangeal (MP) joint. Our series includes 20 patients, with a mean age of 29 years. The mean follow-up period was 42 months. Using the Glickel grading system, 14 patients had excellent results and six had good results. Seventeen patients had no pain and three complained of mild pain with weather changes. Fourteen patients regained full stability of the MP joint and six had mild laxity. The mean loss of pinch strength was 18% compared with the contralateral thumb. The mean loss of motion at the metacarpophalangeal joint was 21%.     

The ECRL bone-tendon ligamentoplasty for chronic ulnar instability of the metacarpophalangeal joint of the thumb

We report the results of a new bone-tendon ligamentoplasty for the reconstruction of chronic injuries of the ulnar collateral ligament at the metacarpophalangeal joint of the thumb. The mean follow-up period was 36 months. Using the Glickel grading system, seven patients had excellent results and one patient had good results. The mean loss of pinch strength was 10% compared with the contralateral thumb. The mean loss of motion at the MP joint was 8%. This technique successfully restores the desired long lasting stability while maintaining mobility of the thumb's metacarpophalangeal joint.     

Surgical repair of acute collateral ligament injuries in digits with the Mitek bone suture anchor

Eighteen acute grade III collateral ligament injuries were treated by using the Mitek bone suture anchor. Seven were thumb metacarpophalangeal joint injuries, and eleven were finger proximal interphalangeal joint injuries. Seventeen patients were followed more than 12 months after surgery. All patients were able to use the digits in daily living activities within 5 weeks after surgery, and return to their original work or sports activities within 12 weeks. Pain was completely relieved in 15 patients. Loss of joint motion averaged 7 degrees. In all joints the postoperative lateral stress angle was within 10 degrees of that of the contralateral digit.     

Results of surgical treatment of acute and chronic grade III [corrected] tears of the radial collateral ligament of the thumb metacarpophalangeal joint

PURPOSE: Radial collateral ligament (RCL) injuries of the thumb metacarpophalangeal (MCP) joint are much less common than ulnar collateral ligament injuries. Cast or splint immobilization is recommended for treating grade I and grade II tears; however, there is no consensus for treating grade III (complete) tears of the RCL. The purpose of this study was to assess the results of repair of acute grade III tears of the RCL and evaluate the efficacy of late reconstruction for chronic instability. METHODS: From 1986 to 2001 there were 26 patients (16 in the repair group, 10 in the reconstruction group) who were reviewed retrospectively and examined clinically after either repair or reconstruction of the RCL of the thumb. The repair group had surgery at a mean of 2.5 weeks after injury and was evaluated at a mean follow-up time of 4.6 years. The reconstruction group had surgery at a mean of 6.8 months after injury and was evaluated at a mean follow-up time of 5.0 years. RESULTS: At an average follow-up of 59 months, there were no statistically significant differences in MCP or interphalangeal joint motion, grip or pinch strength, or MCP joint stability between the 2 groups. Based on a newly developed grading system there were 12 excellent and 3 good results in the repair group and 8 excellent and 2 good results in the reconstruction group. Overall satisfaction was excellent for both groups. CONCLUSIONS: We recommend the repair of acute grade III RCL injuries and reconstruction of chronic grade III RCL tears of the thumb MCP joint to prevent the development of a painful unstable thumb and possibly to prevent the development of MCP joint arthritis. TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic, Level IV.     

Radial collateral ligament injury of the thumb with a Stener-like lesion

The original Stener lesion, described in 1962, refers to an ulnar collateral ligament tear of the thumb metacarpophalangeal joint with adductor aponeurosis interposition. The adductor aponeurosis serves as a mechanical block to healing by preventing apposition of the torn ends of the ulnar collateral ligament. This article presents a case of a 27-year-old woman with painful swelling of the thumb metacarpophalangeal joint following a car accident. Complete tear of the radial collateral ligament was diagnosed based on physical and radiographic examinations. Radial collateral ligament injuries are reported to be less common than ulnar collateral ligament injuries, and, in the past, radial collateral ligament tears were thought to be innocuous, requiring little intervention. More recently, the significance of these injuries has been well documented, and there is support for acute surgical management of complete radial collateral ligament tears. During surgical intervention in our case, we found an intrasubstance tear of the radial collateral ligament with the proximal portion of the ligament retracted and lying superficial to the abductor aponeurosis, thereby producing a Stener-like lesion on the radial side of the joint. The incidence of a Stener-like lesion to the radial collateral ligament is unknown, but it has only been reported once in the literature. Although a primary radial collateral ligament tear may heal by soft tissue apposition, we felt that conservative management in our patient would unlikely lead to healing due to interposition of the abductor aponeurosis. This case supports current recommendations for surgical intervention of complete radial collateral ligament injuries due to the possibility of a Stener-like lesion with soft tissue interposition recurring in the future.     

Gamekeepers thumb: a prospective study of functional bracing

Patients with acute thumb metacarpophalangeal joint injuries were assessed by stress radiography, arthrography, and clinical examination. Arthrograms served to assess tissue injury by the extent and location of dye leaks including the differentiation of displaced (Stener lesion) from undisplaced tears of the ulnar collateral ligament. Patients were treated for a minimum of 6 weeks by use of a removable custom-fit splint and daily range of motion exercises, and followed at a minimum of 1 year. In the 32 patients available for follow-up, mean relative instability improved from 17 degrees (after injury) to 2.3 degrees (follow-up) (p = 0.0001). Functional and subjective outcomes were good or satisfactory in more than 90% of patients; outcomes for all patients with Stener lesions were satisfactory, although joint stabilization was less than in the whole group. The three failures involved persistent symptoms, that defied subsequent surgery. These cases could not be predicted from the initial clinical tests. The treatment regimen was an economical, noninvasive, and effective method for a range of acute thumb metacarpophalangeal joint injuries.     

Chronic finger joint instability reconstructed with bone-ligament-bone graft from the iliac crest

Five patients with chronic instability of digital joints presented with instability and functional disability. Two patients had ulnar collateral ligament damage of the thumb metacarpophalangeal joint and another had chronic multidirectional instability due to radial collateral ligament, dorsal capsule and palmar plate laxity of the metacarpophalangeal joint of the thumb. The fourth patient had a lax radial collateral ligament and palmar plate of the proximal interphalangeal joint of the little finger and the fifth had chronic laxity of the ulnar collateral ligament of the interphalangeal joint of the thumb. All were reconstructed with bone-ligament-bone graft harvested from the iliac crest. The graft was fixed with screws and joint stability was achieved intra-operatively in all patients. All patients achieved a stable joint with improved functional performance at final follow-up.     

Ultrasonography may be misleading in the diagnosis of ruptured and dislocated ulnar collateral ligaments of the thumb.

To find out if a non-invasive technique (ultrasonography) was able to identify a dislocated ligament of a metacarpophalangeal joint of the thumb with instability of the ulnar collateral ligament, 14 consecutive patients with clinical rupture of the ulnar collateral ligament were examined with ultrasonography before the ligament was explored. At exploration all ligaments were ruptured, and only five out of the 14 were dislocated. Ultrasonography recognised only two of the dislocated ligaments, and in half of the 14 patients the ultrasound scan gave incorrect information about the position of the ligament. We conclude that ultrasonography is not adequate for identifying dislocated ulnar collateral ligaments of the metacarpophalangeal joint of the thumb, and exploration is indicated in those with clinical instability in which palpation either suggests a dislocated ligament or is inconclusive.     

The use of ultrasound in the diagnosis of injuries of the ulnar collateral ligament of the thumb

We describe the use of a specialist referral clinic and ultrasound assessment for all injuries to the ulnar collateral ligament of the metacarpophalangeal joint of the thumb presenting to an Accident and Emergency (A&E) department. Senior House Officers in the A&E department were able to correctly diagnose only 45% of the ruptures of the ulnar collateral ligament. The overall agreement between specialist clinic examination and ultrasound for injury to the ulnar collateral ligament was 85% (kappa 0.647). When compared with the operative finding ultrasound had a positive predictive value for rupture of 94%. An algorithm is presented for the assessment of injuries to the ulnar collateral ligament in A&E departments.
