Abstract
Imaging of the wrist with MR imaging can be difficult because of the small size of this joint, its complex anatomy, and its sometimes poorly understood pathologic lesions. A recent study by Hobby and coworkers of 98 patients revealed that MR imaging of the wrist influences clinicians' diagnoses and management plans in most patients. This article summarizes the current diagnostic criteria that can be useful in interpreting abnormalities of the wrist ligaments and triangular fibrocartilage complex (TFCC) of the wrist in this difficult topic in joint MR imaging.

Abstract
Open repair technique of the ulnar disruption of the triangular fibrocartilage complex is described. This technique is indicated for a fresh or a relatively fresh (less than 1 year after the initial injury) ulnar foveal detachment tear, horizontal tear, and proximal slit tear of the triangular fibrocartilage complex, all of which are accompanied by severe dorsal, palmar, or multidirectional instability of the distal radioulnar joint. A chronic tear greater than 1 year from initial injury and a fresh triangular fibrocartilage complex tear without distal radioulnar joint instability, such as central slit tear, are excluded from our indications. A dorsal C-shaped skin incision, a longitudinal incision of the radial edge of the extensor carpi ulnaris subsheath and the dorsal distal radioulnar joint capsule, exposes the distal radioulnar joint. A small, 5-mm longitudinal incision at the origin of the radioulnar ligament exposes its fovea detachment and/or the proximal slit tear of the triangular fibrocartilage complex. The disrupted radioulnar ligament is sutured in a pullout fashion to the ulna with a 3-dimensional double mattress technique through 2 bone tunnels that is precisely made at the central portion of the fovea with 1.2-mm K-wire. An additional horizontal mattress suture is used for closure of the small incision made at the radioulnar ligament, then the extensor carpi ulnaris is repaired. This open-repair technique is complex and requires precise technical skills; however, early results have been more rewarding than the conservative treatment.

Abstract
Lesions of the TFCC are currently a diagnostic and therapeutic challenge. Disc-injuries are often not identified and, therefore, acute ruptures are unfortunately not always immediately repaired. Moreover, therapeutic measures are still sparse and informative trial results are lacking. An anatomical, pathological, diagnostic and therapeutic comparison with the meniscus of the knee is possible.

Abstract
PURPOSE Treatment of ulnocarpal abutment (UAS) syndrome involves decompression of the pressure and impingement, or abutment of the ulnocarpal articulation. Debridement of triangular fibrocartilage complex (TFCC) tears alone in the patient with UAS may have a failure rate of as much as 25% to 30%. Ulnar shortening osteotomy (USO) can be an effective treatment of failed TFCC debridement. Good results have been reported with combined arthroscopic TFCC debridement and mechanical arthroscopic distal ulnar resection. Similar results have been reported with both ulnar shortening osteotomy and open wafer distal ulnar resections in the UAS patient. Because all of these treatment choices appear to yield similar relief of symptoms, determination of the optimal treatment protocol remains a point of debate. The purpose of this study was to evaluate 2 different surgical treatments for UAS. TYPE OF STUDY Retrospective review. METHODS Eleven combined arthroscopic TFCC debridement and arthroscopic distal ulna resections (arthroscopic wafer procedures; AWP) were compared with 16 arthroscopic TFCC debridement and USOs. All patients had diagnostic wrist arthroscopy and arthroscopic TFCC debridement. All patients presented with ulnar wrist pain or neutral or positive ulnar variance, and all experienced at least 3 months of failed conservative management. RESULTS At mean follow-up times of 21 and 15 months, respectively, 9 of 11 patients showed good to excellent results after arthroscopic TFCC debridement and AWP compared with 11 of 16 after arthroscopic TFCC debridement and USO. A statistically significant difference (P <.05) in the complication rates was identified, including secondary procedures and tendonitis. One secondary procedure and 2 cases of tendonitis were seen in the arthroscopic wafer group. CONCLUSIONS Combined arthroscopic TFCC debridement and arthroscopic wafer procedure provides similar pain relief and restoration of function with fewer secondary procedures and tendonitis when compared with arthroscopic TFCC debridement and USO, for the treatment of UAS. LEVEL OF EVIDENCE Level III.

Abstract
PURPOSE This study reviews the results of acute repair of peripheral ulnar-sided triangular fibrocartilage complex (TFCC) detachment associated with intra-articular distal radius fractures. TYPE OF STUDY Two-year follow-up of patients who had undergone acute TFCC repair. METHODS Fifty-six patients underwent arthroscopically assisted treatment of intra-articular distal radius fractures using external fixation and adjunctive percutaneous pinning between 1994 and 1998. Thirteen patients with an acute, complete tear of the ulnar attachment of the TFCC were treated using arthroscopic repair of the TFCC in addition to stabilization of the radius fracture. All patients were evaluated at a mean of 24 months (range, 17 to 35 months) with a physical examination, wrist radiographs, and a Disability of Arm, Shoulder, and Hand (DASH) module outcome assessment questionnaire. RESULTS Average wrist flexion, extension, pronation, and supination were 67.3, 61.8, 79.1, and 86.8, respectively. The average grip strength was 78% of the uninjured side. The results of the Gartland and Werley grading system were good to excellent in 12 patients and fair in 1 patient. The DASH outcome scores revealed a mean functional score of 13 and a mean athletic score of 12. None of the patients reported ulnar-sided pain at follow-up. CONCLUSIONS Arthroscopically assisted TFCC repair in conjunction with distal radius fixation resulted in a high degree of patient satisfaction and good to excellent clinical outcomes.

Abstract
Post-traumatic abnormality of the distal radioulnar joint (DRUJ) still presents a therapeutic challenge to orthopaedic surgeons. The most common difficulty is a failure to diagnose these injuries early, resulting in chronic post-traumatic disorders of the DRUJ. The main aim of therapy is to avoid adverse sequelae. This is of particular importance in malunion of the distal radius, the most common cause for post-traumatic disorders of the DRUJ. Distal radial malunion can be avoided by early appropriate treatment and the need for subsequent ulnar procedures reduced. Ulnar procedures for post-traumatic disorders of the DRUJ are intended to improve function and to decrease pain. Many methods to improve post-traumatic DRUJ function have been described. This article reviews the current state of the art in dealing with post-traumatic disorders of the distal radioulnar joint and presents algorithms to help in decision making.

Abstract
The purpose of this study is to evaluate arthroscopic ulnar shortening with the holmium:yttrium-aluminum-garnet (Ho:YAG) laser for the treatment of ulnocarpal abutment syndrome (UAS). This is a retrospective review of the experience of a single surgeon using this technique between 1994 and 2000. Unloading the ulnocarpal joint is the recognized treatment of UAS. Ulnar shortening via a diaphyseal osteotomy and plating (USO) has been used with good results; however, nearly 50% of patients will require hardware removal. Researchers have reported similar results between open distal ulnar resection (the wafer procedure) and USO for the treatment of UAS. Researchers have also reported similar results with mechanical arthroscopic distal ulnar resections (arthroscopic wafer distal ulnar resection [AWP]) for UAS. Eleven patients who underwent Ho:YAG laser-assisted arthroscopic distal ulnar resection were retrospectively evaluated. The average follow-up time was 31 months, with a range of 7 to 61 months. Evaluation using Darrow' s criteria revealed 64% excellent (7 of 11), 18% good (2 of 11), 9% fair (1 of 11), and 9% poor (1 of 11) results. The average return to work time was 4.7 months, with a range of 1.5 to 16 months. Complications included 1 repeat surgery for ulnocarpal scar formation, 2 cases of transient tendonitis, and 1 portal site erythema without drainage that was treated with antibiotics. One patient (the one with a poor result) has not returned to work for unrelated reasons. chi- square analysis (P <.05) was unable to identify a statistical difference between the reported results of arthroscopic wafer procedures, USOs, and open wafer procedures. We concluded that Ho:YAG laser-assisted arthroscopic ulna shortening procedures show similar results to those reported for arthroscopic wafer procedures, open wafer procedures, and USOs. Return to work times are similar to those reported by other researchers, as is the return to preoperative occupation rate. There is no need for late removal of hardware, as is sometimes associated with USO. Our experience has been that the Ho:YAG laser removes hyaline cartilage and subchondral bone rapidly and with little debris, and thus facilitates the ulna shortening procedure.

Abstract
Neutral rotation radiographs of the wrist are recommended to standardize the measurement of ulnar variance because it is known that changes in forearm rotation result in changes of this measurement. The purpose of this study was to examine whether there are clinically measurable differences in ulnar variance between radiographs in various degrees of forearm rotation in human subjects. Forty-five wrist radiographs of 15 normal adults were obtained in 3 positions: maximum forearm pronation, neutral rotation, and maximum supination. The ulnar variance on each view was measured by 3 independent observers using a standard millimeter ruler. The average absolute difference in ulnar variance was 0.4 mm between pronation, 0.6 mm between pronation and supination, and 0.2 mm between neutral and supination. Although we found a statistically significant difference in ulnar variance between the pronated and neutral positions, this difference may not be clinically significant and may not justify concerns of forearm position during the radiographic evaluation of ulnar variance.

Abstract
Because a certain percentage of patients with positive ulnar variance experience incomplete pain relief after triangular fibrocartilage complex (TFCC) debridement alone, we prospectively evaluated the feasibility and efficacy of combining arthroscopic TFCC debridement with arthroscopic wafer resection in such wrists as part of the same surgical procedure. We enrolled 12 patients between July 1998 and July 2000 and performed both subjective and objective assessment at follow-up with a minimum of 6 months and an average of 14 months. Seven posttraumatic and 5 degenerative tears were identified. Preoperative ulnar variance with a pronated grip x-ray averaged 2 mm and ranged between 1 and 4 mm. At final review 8 patients experienced complete pain relief and 4 experienced only minimal symptoms. The ulnocarpal stress test failed to elicit pain in any wrist. Nine patients were very satisfied, and 3 were satisfied. Grip strength improved 8 kg (36%). This procedure should be considered in the treatment of ulnar wrist pain when TFCC tears and positive ulnar variance coexist.

Abstract
Ulnar shortening osteotomy was performed in 11 wrists with ulnar abutment syndrome, after failed arthroscopic surgery on the TFCC (ten debridements, one repair). A delayed union was present in three, a non-union occurred in two, of whom one needed a revision and grafting procedure. According to the Mayo wrist score, only four had an acceptable outcome. Patient's satisfaction was higher: seven were satisfied, four were not. The postoperative wrist pain score was good in ten patients. Overall outcome was not very successful. Problems related to the procedure could be avoided by adapting the technique (oblique osteotomy, palmar placement of the plate, and compression devices). The key statement remains however to us; ulnar sided wrist pain thought to be caused by an ulnar abutment is not necessarily resolved by decompressing the ulnocarpal joint.

Abstract
Ulna-shortening osteotomy has become a standard procedure for various ulnar-sided wrist disorders. A precise osteotomy, good coaptation of the osteotomy surfaces, and rigid internal fixation are mandatory to achieve good results from ulna-shortening osteotomy. Various techniques and devices have been introduced to assist in this difficult procedure. We developed a device that enables a precise ulna-shortening osteotomy and fixation with a 3.5-mm AO dynamic compression plate. Twenty-four ulnas were shortened with the aid of this device. The average follow-up period was 36 months. Radiologic union occurred at an average of 8.1 weeks after surgery. There were no nonunions or delayed unions. This study shows that an ulna-shortening procedure with this device enables precise shortening and predictable union of the ulna.

Abstract
The gripping rotatory impaction test (GRIT) is performed with a standard grip dynamometer and provides a quantitative measure for identifying ulnar impaction. The purpose of this study was to determine whether patients with unilateral ulnar impaction syndrome (UIS) have a GRIT ratio on the involved side greater than 1.0 while the GRIT ratio on the uninvolved side is no different from 1.0. Twenty-four patients with unilateral UIS were tested with the GRIT on both the symptomatic, involved side and the asymptomatic, uninvolved side. The GRIT was performed with a standard grip dynamometer, and testing alternated between each patient's involved and uninvolved sides, with the wrist in the neutral, supinated, and pronated positions, in that order. The GRIT ratio on the involved side, at 1.37, was significantly greater than 1.0, while the GRIT ratio on the uninvolved side, at 1.03, was not significantly different from 1.0. The GRIT ratio is a quantitative measure that identifies UIS and can be used as an adjunct to imaging studies and qualitative clinical tests for UIS. The GRIT may also be helpful in determining which patients with UIS might benefit from surgical ulnar shortening.

Abstract
The treatment of triangular fibrocartilage tears in the athlete presents more of a rehabilitation challenge than a surgical technique challenge. The rehabilitation regimen is a function of the sport. Although injuries to the shoulder and knee can be career ending, injuries to the TFCC usually, but not always, can be treated successfully.

Abstract
Although dynamic increases in ulnar variance may accompany functional activity, radiographic assessment of ulnar variance traditionally has used a neutral rotation x-ray of the wrist that provides an image of the radioulnar length with the wrist unloaded. Such a view may underestimate variance in wrists in which power grip and pronation result in significant proximal migration of the radius. This study investigates the effect of a maximum grip effort in combination with forearm pronation on ulnar variance in 22 patients who presented with ulnar wrist pain. The pronated grip x-ray view resulted in statistically significant increases in ulnar variance. Preoperative ulnar variance should be measured using both neutral rotation and pronated grip x-rays before selecting treatment for causes of ulnar wrist pain that are affected by radioulnar length so that dynamic increases in ulnar variance are considered when operative treatment is necessary.

Abstract
Thirteen wrists with ulnar neutral or negative variance were treated by open distal ulna excision (the wafer procedure). The mean follow-up was 25 months (range, 12-38). At final follow-up grip strength had increased a mean of 14 kgf and 12 of the 13 patients were very satisfied with the functional outcome and pain relief. In treatment of the ulnar impaction syndrome, the wafer procedure provides excellent pain relief and functional restoration particularly in patients with ulnar neutral or negative wrists in whom triangular fibrocartilage tears have not yet developed.
